Abstract
Systems and methods for monitoring the location of a patient using an integrated belt and sensor for alarm for patient furniture. The belt may include at least one strap and a slider configured to be releasably attached to one another and an alarm system that is triggered when the slider is disengaged from the other strap or straps. By doing so, the amount of time it takes to remove the belt can be increased, which provides medical personnel additional time to reach a patient. Additionally, the system may include additional components to allow a patient to move side-to-side relative to the furniture or device. For instance, where the furniture is a bed, side-to-side movement is desired for added comfort. The system may include a slider enabling the belt to be adjustable for patients of any number of different sizes.

However, it is not intended that the invention be limited to the specific terms so selected and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose. For example, the words “connected”, “attached”, or terms similar thereto are often used. They are not limited to direct connection but include connection through other elements where such connection is recognized as being equivalent by those skilled in the art.
DESCRIPTION OF PREFERRED EMBODIMENTS
[0077] The present invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments described in detail in the following description.
1. System Overview
[0078] The current invention relates to a belt with multiple straps portions which is connected to an alarm system, preferably an audible reminder, that can be secured around an occupant of a chair, bed, or other supporting device to monitor patient movement non-invasively. When a first releasable strap portion is disengaged by pulling in a first direction, an alarm will sound. For instance, the invention allows an audible reminder to be sounded before a patient is able to leave the chair, bed, or other supporting device, for instance, for a period of time such as 5-7 seconds after an event occurs. This is beneficial for multiple reasons. First, this delay helps to give a caregiver time to check in on the patient before he or she is able to stand up. Also, this audible reminder helps to remind the patient that he or she should wait for a caregiver to help him or her up from the chair, bed, or other furniture, or that the patient should ask for assistance. When a first releasable strap portion is disengaged by pulling in a first direction, an audible reminder will sound. The second releasable strap portion can then be disengaged by pulling in a second direction, which is opposite to the first direction. This gives an early warning to the medical personnel before the occupant attempts to exit the chair or bed. As a result, the necessary staff has time to intervene to assist the occupant who may be a fall risk. The belt could either be disposable or reusable based on the materials used. By offering both disposable and reusable belts, cost efficiency can be optimized depending on the specific context in which the belt is used. This invention is superior to previous sensor pads or alarms that typically only sound once the occupant has already exited the chair, bed, or other supporting device. The invention provides the earliest possible warning that a patient is at immediate risk of falling when exiting the bed, while also being non-invasive.
[0079] Additionally, the current invention may also include features that allow for increased range of motion when a patient is secured to a device, such as a piece of furniture including a bed. These features can easily be incorporated with various disposable alarmed belts, some of which have two release points that provides a health care provider with an early warning that a patient is trying to leave the furniture. This early warning can provide the provider with additional time to intervene prior to a potential fall. The invention may be made of various low-profile, soft materials to avoid potential pressure injuries. The invention may also be made of hydrophobic material and flat surfaces to simplify cleaning. Further still, the invention may be compatible with a variety of different devices and furniture. Preferably, the invention is of a simple design with minimal components to support the ease of use by end users.
[0080] The current invention may also include further features to optimize use. For instance, the belt may be made of multiple different materials attached to one another having different characteristics. For instance, the outer side of the belt may be made of a slippery material, whereas the interior of the belt may be made of a high-friction or less slipper material. This may allow the outside of the belt, and thus the belt and the user, to easily move relative to the bed or other furniture, for instance when a user moves or rolls from side to side on a bed. At the same time, the less slippery inner material may help to ensure the belt remains in place relative to the patient. Further still, the slippery outer material may easily be wiped down to remove materials that may fall onto the belt. Also, the belt may be made of soft wicking material and include foam material therein for patient comfort. The belt may also be substantially water resistant or waterproof, hydrophobic, and wipeable.
[0081] Additionally, the belt may include a slider. The slider may be used to enable adjustability of the length of the belt depending on the size of a patient. In fact, the slider may be configured to allow for adjustability of the belt even once it is installed to the bed, frame, furniture, or other device. The slider may be configured to slide relative to the belt, such that it can initially be located on top of or next to certain components of the belt, after which it can be slid to expose those certain components. For instance, the slider may be slid to expose a second release handle. The slider may be any number of different dimensions, for instance, at least 2 inches in width, at least 4 inches in width, at least 5 inches in width, and over six inches in width, as desired. The slider may make it difficult for a user to access a second release handle located therebeneath. Additionally, the specific dimensions of the slider may vary to help improve ease with which the slider can move relative to the belt. Furthermore, a first release handle associated with the slider may be specifically configured to help optimize the amount of force applied to the handle that is transferred to the underlying strap. For instance, the release handle may terminate directly adjacent to the edge of the underlying strap. This first release handle may be horizontally oriented, parallel with the length of the belt, whereas the second release handle may be vertical oriented, perpendicular with the length of the belt.
[0082] Further still, the belt may have opposing securement straps that secure the belt to either side of the bed or other piece of furniture. For instance, the edges of each of the opposing securement straps may be wrapped outside of a frame associated with the bed, under the frame, and then upwardly such that the edge of the strap secures to the base of the strap. This may occur between the frame and the bed, such that it is difficult to disengage the strap from on top of a bed. This would make it difficult for an individual located on top of the bed and within the belt to remove the securement straps. Instead, it would be easier for an individual who is not secured within the belt to disengage the securement straps. Furthermore, this makes the straps harder to see, which also helps to minimize risk that a user will try to disengage the securement straps from atop of the bed or other furniture.
[0083] Additionally, the belt may be delivery in a use-based configuration that helps to simplify use directly out of the package. For instance, multiple fasteners or other locators may be installed onto the belt. More specifically, at least two hook and loop fasteners may be secured to the bottom side of the belt that help to ensure proper placement of securement straps. Additionally, these hook and loop fasteners help a user to return the belt into the use-based configuration after a user has used the belt. As such, these fasteners serve as strap guides that can easily be broken to ensure patient comfort.
[0084] Further still, the belt may come equipped with a cord that is hidden within a substantial portion of the belt. This allows the length of the cord to extend from the end of the belt to ensure there is appropriate clearance to reach an alarm or audible device.
[0085] Also, the various hook and loops fasteners may come in different strengths based on the materials of the hook and loop fasteners, the size and shape of the hook and loop fasteners, and the like. In this way, certain fasteners may be easier or more difficult to disengage by a user depending on the function they serve. Additionally, compatible hook and loop fasteners may come color coded to help a user quickly and easily identify which hook fasteners align with which loop fasteners.
[0086] Additional features and benefits of the present invention may include: [0087] Both sides of bed attachment straps may be of the blue lower friction, hydrophobic materials [0088] Labels added to bed attachment straps that say “This side facing out” to help with product application to the bed [0089] Yellow handles may be: [0090] Shortened handles to center handles on the belt, makes it easier for patients to reach the handles. [0091] Rotated the inner handle so it cannot be accessed without removing the slider [0092] Adjusted sewing on the first handle to better apply the force in a “peel” manner [0093] Bed attachment straps white Hook &Loop—may be changed to Velcro “Onewrap”, this product is both the hook and the loop. Less likely to drag on the bedsheets, fewer parts for manufacturing. [0094] Two-sided product label—one side has the standard info, one side has the warning. [0095] Slider loop update [0096] May be 2″ wide with blue fabric touching the patient. [0097] May also be 5″ wide and now only orthowick touches the patient [0098] Early indication of unassisted bed exit [0099] Patient can self-release, so this is not a restraint [0100] Dual release sensor: Sensor activates alarm at first release. Patient can exit after second release. This provides earlier notification to caregivers (an additional 5-7 seconds) [0101] Notification enabled by connection/integration to existing Posey Alarms and Nurse Call system, if applicable. [0102] Release points include bright yellow handles—easy to see/grab from any angle [0103] Belt allows patient to roll and turn in bed, (to minimize disruptions to sleep, support patient comfort) [0104] Strap design [0105] Belt moves with patient, allowing patient to roll, but not to roll out of bed when used with side rails (per facility protocol) [0106] High performance materials to facilitate patient comfort [0107] 5″ wide [0108] Orthowick™ material (inner, patient facing) [0109] Breathable [0110] Moisture wicking properties [0111] Smooth/soft against skin, [0112] Low friction material (outer) [0113] Reduce shear forces by allowing belt to move with patient within bed (vs. patient moving within belt) [0114] wipeable, spot-cleanable (single patient use for 30 days) [0115] Belt is easy to adjust to a variety of sizes [0116] Simple sliding handle [0117] One embodiment is configured for 24-42″ waist size [0118] Another embodiment is configured for 38-56″ waist size [0119] Secure, easily adjusted Bed attachment straps [0120] Secured by high strength hook and loop [0121] Intuitive—labels on straps [0122] Reduces tampering—H&L not accessible to patients [0123] Adjustable for a variety of different beds, for instance, 34″ to 40″ wide
[0124] Additional modifications may include: [0125] Same dual-release concept [0126] Wider [0127] Different material (covered above) [0128] Sliding handle so adjustability is on belt/in front of patient, vs chair, where it is in the back
[0129] Further additional modifications may include: [0130] This has a sensor that connects to Posey Alarms, activates at first release to provide caregiver notice and extra time [0131] Still self-release, so not a restraint [0132] This Velcro is easier to release for a patient [0133] Patient can still turn/roll in bed [0134] Belt is made with softer, gentler material
2. Detailed Description of Preferred Embodiments
[0135] The inventive double-release alarm belt 30 is generally shown in the figures. The double-release alarm belt 30 is used to monitor the position of a patient 34 or other individual who is resting on a support device 32; for instance, a chair, a bed, a wheelchair, a cardiac chair, a recliner, or other furniture. The double-release alarm belt 30 has a first elongated strap 36, a second elongated strap 64, and an alarm system 80. The double-release alarm belt 30 may also include a shortened strap 52. The first elongated strap 36, the second elongated strap 64, and the shortened strap 52 may be releasably affixed to one another about a first portion 112 and a second portion 114, as will be further described below. When the first elongated strap 36 and the second elongated strap 64 are disengaged about the first portion 112, the alarm system 80 may create an audible alarm. In this way, the double-release alarm belt 30 provides medical personnel with an advanced warning before the patient 34 is able to disengage the second elongated strap 64 from the shortened strap 52 about the second portion 114 to get up from the device 32.
[0136] Initially, the first elongated strap 36 will be described. The first elongated strap 36 can be seen, for instance, in
[0137] Moving on, the shortened strap 52 also has a first end 54 and a second end 56 opposite the first end 54, as well as an upper side 58 and an underside 60. The shortened strap 52 is best seen in
[0138] Next, the second elongated strap 64 will be described, which again is best seen in
[0139] In an alternative embodiment, see
[0140] Next, the slider 1038 will be described, see
[0141] Next, the first elongated strap 1036 will be described, see
[0142] The first end 1048 may be releasably secured to the second end 1050. More specifically, the first end 1048 may have a first fastener 1060 located on the underside 1058 of the belt, and the second end 1050 may have a second fastener 1062 located on the upper side 1056 of the belt 1030. For instance, these fasteners 1060, 1062 may be of a compatible hook and loop fastener material, which would allow the first end 1048 and the second end 1050 to be releasably secured to one another. The illustrated second fastener 1062 may be elongate and extend along a substantial portion of the strap 1036. See
[0143] Additionally, as seen in
[0144] Also, the first elongated strap 1036 may include additional fasteners located on the upper side 1056 that can help to appropriately locate the securement straps 1082, 1084 in place. More specifically, as shown in
[0145] While a number of fasteners are described above as hook and loop fasteners, other types of fasteners could similarly be used, such as snaps, adhesive, ties, and the like. Additionally, as shown and mentioned above, any of the compatible fasteners can be color-coded to simplify the assembly or re-assembly process. For instance, the first fastener 50 and the fourth fastener 78 are made of white hook and loop fasteners. Similarly, the second fastener 62 and the third fastener 76 are made of blue hook and loop fasteners. In this way, medical personnel can easily re-assemble the double-release audible reminder belt 30 without risk of engaging the wrong fasteners with one another. This is especially helpful where the double-release alarm belt 30 is reusable. Also, the handles 64, 74 can be a different color from the rest of the double-release audible reminder belt 30, so that they can more easily be seen and distinguished from the other parts of the belt 30. For instance, the handles 86, 88 may be a fluorescent yellow. Further still, depending on the functionality of the fasteners, hook and loop fasteners having a varying level and securement to one another may be used. For instance, where the fasteners should be easily separated, the bond between the hook and loop fasteners will be less strong than the bond between hook and loop fasteners associated with components that need to be more securely fastened to one another.
[0146] Each of the components above, including the first elongated strap 36, the shortened strap 52, the second elongated strap 64, and the slider 1038 may be disposable. Additionally, the cord 110, which can be disengaged from the audible reminder system 80, can also be disposable. For instance, the disposable version of the belt 30 could be made of a silver conductive fabric, as well as a nylon or foam laminate. These materials are typically less expensive in comparison to the materials needed to manufacture previous reusable belts. Additionally, the disposable version could have hook and loop fasteners as opposed to buckles, which can be expensive. For instance, the disposable materials may be 25-75% less expensive than those associate with traditional belts, and more preferably 40-50% less expensive than traditional belts. Such a configuration would be especially appealing in situations where the double-release audible reminder belt 30 is used in hospital settings or other environments where sterility must be maintained. By having an affordable disposable alarm belt 30, the belt 30 can simply be thrown away after use without the need to sterilize a previously-used belt, which can be time-consuming and costly. Alternatively, in situations where sterility is not a concern, the double-release audible reminder belt 30 could be reusable. For instance, such a configuration could include materials such as nylon webbing, seat belt buckles, biothan webbing, and silver conductive fabric. Alternatively, any aspect of the belt 30 could be made of any other number of materials, including non-woven materials, such as plastic or paper. Regardless of the material, the belt 30 is preferably configured to be able to withhold forces of over 100 pounds before failure.
[0147] Possible dimensions of the first elongated strap 36, the shortened strap 52, and the second elongated strap 64 will now be described. However, it should be noted that straps of various dimensions may be used to accommodate different uses. Additionally, it should be noted that larger straps could be used for patients with larger waist sizes or for use with larger chairs, beds, cardiac chairs, recliners, and the like.
[0148] For instance, the length of the double-release alarm belt 30 could be approximately 60-100 inches in length and, more preferably, approximately 78 inches, as shown in
[0149] An alternative double-release alarm belt 30 could be much longer. For instance, the length of the double-release alarm belt could be approximately 70-110 inches in length and, more preferably, approximately 92 inches as shown in
[0150] Functionality of the cord 110 and audible reminder system 80 will now be described. The cord 110 is embedded within the first or second elongated strap 36, 64 and one of the securement straps 82, 84 and monitors the locations of the fasteners 78, 80. More specifically, when the fourth fastener 78 is pulled away from the first fastener 50, the cord 110 transmits this information to the audible reminder system 80, and the audible reminder system 1040 generates an audible reminder. For instance, an electrical circuit can be completed where the fasteners 50, 78 are connected to one another. When these fasteners 50, 78 are pulled apart from one another, the electrical circuit can be interrupted. Once the circuit is interrupted, the audible reminder can be triggered. Alternatively, a cord need not be included with the system, but instead, a wireless or Bluetooth system could be used to wirelessly trigger the audible reminder system 80 to generate the audible reminder when the fasteners 78, 80 are separated. The double-release audible reminder belt 30 can be used with any number of various fall-prevention audible reminder systems, as known to those of skill in the art. For instance, the belt 30 can be used with various POSEY® fall audible reminders, including POSEY KEEPSAFE, POSEY KEEPSAFE DELUXE, POSEY KEEPSAFE SCOUT, and POSEY SITTER ELITE fall audible reminders.
[0151] To assemble the double-release alarm belt 1030, the first fastener 1050 is releasably engaged with the fourth fastener 1078 and the second fastener 1062 is releasably engaged with the third fastener 1076. Once the double-release alarm belt 1030 has been assembled, it can be installed about the patient 1034. Initially the strap 1082 is secured relative to the device 1032 as seen in
[0152] To assemble the double-release audible reminder belt 30, the first and second fasteners 60, 62 are releasably engaged with one another. The location where these fasteners 60, 62 can be determined based on the size the patient 34, the specific device 32 being used, etc. Thereafter, the slider 1038 is moved relative to the first elongated strap 36 to a desired location, after which the top fastener 80 and bottom fastener 78 are engaged with one another. The securement straps 82, 84 may be installed relative to the device 32 before the various fasteners 60, 62, 78, 80 are engaged, or thereafter. Because of the configuration of the various fasteners 60, 62, 78, 80 and the slider 1038, the size of the belt 30 may be varied depending on the size of the patient 34 even after the securement straps 82, 84 have been installed. Previous embodiments would require the securement straps 82, 84 to be reconfigured to accommodate differently sized patients. Finally, once the belt 30 has been appropriately installed, the audible reminder cord 39 is connected to the audible reminder system 1040 by inserting a jack (not shown) into a port (not shown) of the audible reminder system 1040. Thereafter, the audible reminder system 1040 is turned on.
[0153] Once the belt 30 has been installed, the position of the patient 34 about the device 32 can be monitored. In the event the patient 34 begins to disengage the double-release audible reminder belt 30, the medical personnel will be notified. This first occurs when the fasteners 78, 80 are pulled apart with a first force 102, such that the bond 98 between these fasteners 50, 78 is interrupted. Preferably, due to the locations of the fasteners 50, 78 relative to the first elongated strap 36 and the second elongated strap 64 and/or slider 1038, the separation of these fasteners 78, 80 occurs by pulling the second end 56 of the first elongated strap 36 and/or the release handle 74 in a first direction. As described above, once these fasteners 78, 80 are pulled apart, the audible reminder will sound to notify medical personnel that the patient 34 is trying to get out of the device 32. Next, the fasteners 60, 62 are pulled apart with a second force 104, such that the bond 100 between these fasteners 62, 76 is interrupted. In some embodiments, the first force 102 required to disengage the first fastener 50 and the fourth fasteners 78 is less than the second force 104 required to disengage fasteners 60, 62. Due to the locations of the fasteners 62, 76 relative to the first elongated strap 36 and the second elongated strap 64 and/or slider 1038, the separation of the fasteners 60, 62 occurs by pulling the first end 66 of the second elongated strap and/or release handle 64 in a second direction. Preferably, the first direction 82 is in the opposite direction as the second direction 84. This results in increased time and difficulty for the patient 34 to remove the double-release audible reminder belt 30 than if the patient 34 simply had to repeatedly pull two separate belts in the same direction. Furthermore, as described above, the slider 1038 may initially be covering the second release handle 64. As a result, the user would first need to disengage fasteners 78, 80 using the first release handle 74, after which the slider 1038 would need to be slid away from the second release handle 64 to expose it, after which the second release handle 64 can be grasped to separate fasteners 60, 62.
[0154] Furthermore, the bond 98 between fasteners 78, 80 can be weaker than the bond 100 between fasteners 60, 62. In this way, the patient 34 can more easily disengage the fasteners 78, 80, at which time the audible reminder will be sounded. Thereafter, due to the stronger bond 100 between the fasteners 60, 62, it will be more difficult for the patient 34 to disengage these fasteners 62, 76. This makes it more difficult for the second bond 100 to be broken, which increases the amount of time that medical staff has to approach the patient 34 after the initial alarm has been sounded. In this way, potential falls of the patient can be minimized.
[0155] A method of using the double-release alarm belt 30 will now be described. Initially, the double-release alarm belt 30 is wrapped around the patient 34 as well as the device 32. Next, the first end 38 is engaged with the second end 68 to secure the ends 38, 68 to one another. Additionally, an alarm system 80 is connected to the double-release alarm belt 30, for instance, by a cord 110. Next, the first elongated strap 36 can be disengaged from the second elongated strap 64 about a first portion 112. This can occur when the first handle 86 is pulled to disengage the first elongated strap 36 from the second elongated strap 64 about the first portion 112. Once the straps 36, 64 are disengaged about the first portion 112, the alarm system 80 creates an audible alarm. For instance, this may occur where an electrical circuit is interrupted. Alternatively, various sensors can be used to detect when the straps 36, 64 are disengaged about the first portion 112. Of course, the alarm may be sounded using any other ways known to those of ordinary skill in the art to detect when the two straps 36, 64 are disengaged from one another. Thereafter, the first elongated strap 36 can be disengaged from the second elongated strap 64 about a second portion 114. This can occur when the second handle 88 is pulled to disengage the first elongated strap 36 from the second elongated strap 64 about the second portion 114. Thereafter, the patient 34 is released such that he or she can move away from the device 32. Additional steps may include threading the second end 68 of the double-release alarm belt 30 through the first ring 94 and the second ring 96 associated with the first end 38 of the belt 30 until the double-release alarm belt 30 is snug about the patient 34. Also, the second end 68 of the double-release alarm belt 30 may be held in place using a hook and loop fastener 90.
[0156] Another embodiment of the double-release alarm belt 230 is shown in
[0157] The first elongated strap 236 and the second elongated strap 264 may be releasably affixed to one another about a first portion 312, and the third elongated strap 320 and the fourth elongated strap 322 may be releasably affixed to one another about a second portion 314, as will be further described below. When the first elongated strap 236 and the second elongated strap 264 are disengaged about the first portion 312, the alarm system 80 may create an audible alarm. In this way, the double-release alarm belt 230 provides medical personnel with an advanced warning before the patient 234 is able to disengage the third elongated strap 320 from the fourth elongated strap 322 about the second portion 314 to get up from the device 232.
[0158] Initially, the first elongated strap 236 will be described. The first elongated strap 236 can be seen, for instance, in
[0159] Still looking to
[0160] Moving on, the third elongated strap 320 will be described. The third elongated strap 320 has a first end 324, a second end 326 opposite the first end 324, and a midportion 328 located between the first end 324 and the second end 326. Additionally, the third elongated strap 320 may have an upper side 330 and an underside 332. Further, a third fastener 334 may be associated with the third elongated strap 320. As shown, the third fastener 334 extends along the underside 332 of the third elongated strap 320. Further still, the third elongated strap 320 may have a second handle 288 that is mounted to the upper side 330 of the third elongated strap 320.
[0161] Moving on, the fourth elongated strap 322 will be described. The fourth elongated strap 322 has a first end 336, a second end 338 opposite the first end 336, and a midportion 340 located between the first end 336 and the second end 338. Additionally, the fourth elongated strap 322 may have an upper side 342 and an underside 344. Also, a fourth fastener 346 may be associated with the fourth elongated strap 322. As shown, the fourth fastener 346 extends along the upper side 342 of the fourth elongated strap 322.
[0162] Installation of the belt will now be described. First, the first and second ends of the base are secured to the device 232 as shown in
[0163] As described above, once the third fastener 334 and the fourth fastener 346 are pulled apart by a first force 302, the alarm will sound to notify medical personnel that the patient 234 is trying to get out of the device 232 as described above. Next, the first fastener 250 and the second fastener 262 are pulled apart with a second force 304, such that the bond 300 between these fasteners 250, 262 is interrupted. The first force 302 required to disengage the third fastener 334 and the fourth fastener 346 is less than the second force 304 required to disengage the first fastener 250 and the second fastener 262. Preferably, the separation of the third and fourth fasteners 334, 346 occurs by pulling the second handle 288 in a first direction 282 and the separation of the first and second fasteners 250, 256 occurs by pulling the first handle 286 in a second direction 284 opposite the first direction 282. This results in increased time and difficulty for the patient 234 to remove the double-release alarm belt 30 than if the patient 34 simply had to repeatedly pull two separate belts in the same direction.
[0164] Furthermore, the bond (not shown) between the third fastener 334 and the fourth fastener 346 can be weaker than the bond (not shown) between the first fastener 250 and the second fastener 262. In this way, the patient 34 can more easily disengage the third fastener 334 and the fourth fastener 346, at which time the alarm will be sounded. Thereafter, due to the stronger bond between the first fastener 250 and the second fastener 262, it will be more difficult for the patient 234 to disengage these fasteners 250, 262. This makes it more difficult for the second bond to be broken, which increases the amount of time that medical staff has to approach the patient 234 after the initial audible reminder has been sounded. In this way, potential falls of the patient can be minimized.
[0165]
[0166] Additionally, as shown, the at least one strap also includes a second shortened strap 416. In the illustrated embodiment, the second shortened strap 416 is slidable relative to the first elongated strap 406. More specifically, the second shortened strap 416 is slidable relative to the second end 410 of the first elongated strap 406. In light of this slidable configuration, the second shortened strap 416 can be moved to alter the dimensions of the system 110. This allows a single system 110 to be used with a variety of different patients. For instance, if the patient 404 is smaller, the second shortened strap 416 can be slid away from the second end 410 such that the width of the system is smaller. To the contrary, where the patient 404 is larger, the second shortened strap 416 can be slid until it is directly next to the second end 410. Furthermore, the system 110 may be configured such that at least a portion of the second shortened strap 416 may be slid past the second end 410. In this way, the system 110 can quickly and easily be adjusted such that it is compatible with a wide variety of patients.
[0167] The first elongated strap 406 and the second shortened strap 416 may have various fasteners that allow for temporary, but removable connection between the straps. More specifically, the first elongated strap 406 may have a first fastener 418 located on an upper side 420 for the first end 408. The second shortened strap 416 may have a second fastener 422 mounted to an underside 424. Additionally, the second shortened strap 416 may also include a first handle 423. In such an embodiment, where the second shortened strap 416 is pulled away from the first end 408, for instance using the first handle 423, the connection between the first fastener 418 and the second fastener 422 can be broken. When this occurs, the alarm 414 can be sounded. As described above with regard to the other embodiments, the system 110 may also feature additional fasteners to enable the double-release alarm belt. For instance, additional fasteners (not shown), may be used to connect an underside of the first end 408 to the upper side of the second end 410. This would require a user to first disengage the second shortened strap 416 from the first elongated strap 406, after which the first end 408 and the second end 410 can be disengaged from one another. Because the alarm 414 is sounded based on the initial separation of the second shortened strap 416 from the first elongated strap 406, a caregiver will have time to check on the patient 404 while the second disengagement is occurring. The first elongated strap 406 may include a second handle 419 that can be used to more easily separate the first end 408 from the second end 410.
[0168] Additionally, the system 110 may have multiple securement straps configured to secure the system 110 to the device 402. Still looking to
[0169] As a result of the slidable relationship of the hoops 444, 446 relative to the tracks 434, 440, a patient roll concept is achieved that allows a patient 404 to have greater movement while being safely secured and having two releasing points. This allows a patient 404 to easily and comfortably move side-to-side relative to the device 402. This helps to ensure comfort of the patient 404 while they are in the device 402 and can help to reduce bed sores that can occur where the patient 404 remains in the same position on the device 402 for extended periods of time. The system 110 may even allow a patient 404 to comfortably sit up without disengaging the straps.

[0173] Turning next to
[0174] All of the systems described above can be used in similar ways to enable health care professionals to monitor a patient's location relative to the device, and more importantly, to sound an audible reminder when a patient begins to disengage the system before he or she can get up from the device. Steps associated with a method of using the system will now be described. Of course, the specific order in which the following steps occur may be varied. Initially, at least one securement strap is secured to the device. For instance, first and second securement straps can be used to secure the belt to either side of the device; for instance, a bed or a frame associated there with. Thereafter, a patient may be placed on the belt. Once this occurs, the first and second fasteners associated with the first elongated strap can be engaged with one another at a location that is dependent on the size of the patient. Thereafter, the slider may be slid relative to the elongated strap to an appropriate location. Once this occurs, the bottom and top fasteners are engaged with one another. After this, an audible reminder system may be connected to the alarm system using a cord. From here, at least one securement strap that extends from the patient strap can be secured to a side of the device. The relationship of the patient strap and the securement strap allows the patient to move side-to-side relative to the device for added comfort.
[0175] The method may also include use of additional components to enable this side-to-side movement. For instance, the system may include a track or tracks and hooks that can slide along the track. As such, the system may include a first track on a first side of the patient strap and a second track on a second side of the patient strap. In such an embodiment, hooks travel along the length of the track, and securement straps extend from the hooks to enable side-to-side movement. Alternatively, the system may include at least one adjustable slider that has a securement strap extending therefrom to also enable side-to-side movement. Further still, the system may include a loop with a securement strap that extends therethrough.
[0176] In any of these embodiments, the system may also include multiple releases. For instance, the system may include a first release mechanism and a second release mechanism. When the first release mechanism is released, an audible reminder can be sounded. At this time, the patient is still seated or lying on the device. It is not until the second release mechanism is released that the patient can get up and exit the device.
[0177] All the disclosed embodiments are useful in conjunction with patient monitoring. There are virtually innumerable uses for the present invention, all of which need not be detailed here. All the disclosed embodiments can be practiced without undue experimentation.
[0178] Although the best mode contemplated by the inventors of carrying out the present invention is disclosed above, practice of the present invention is not limited thereto. It will be manifest that various additions, modifications, and rearrangements of the features of the present invention may be made without deviating from the spirit and scope of the underlying inventive concept.
[0179] For example, additional elongated straps, shortened straps, and sliders could be used in conjunction with the straps described above. Similarly, additional fasteners could also be used to increase the amount of time between when the patient begins to remove the belt and when the patient is able to get up from the device. Also, the fasteners need not be in the exact locations described but could be located anywhere about the various straps. In addition, the individual components need not be fabricated from the disclosed materials but could be fabricated from virtually any suitable materials.
[0180] Moreover, the individual components need not be formed in the disclosed shapes, or assembled in the disclosed configuration, but could be provided in virtually any shape and assembled in virtually any configuration. Furthermore, all the disclosed features of each disclosed embodiment can be combined with, or substituted for, the disclosed features of every other disclosed embodiment except where such features are mutually exclusive.
