(23) The platform 25 has a top side, a bottom side forming a four-sided rectangular shape with a dimension that has approximately 36″ longer sides, 12″ shorter sides, and a central cut out 34 having two long sides of approximately 32 inches and two short sides of approximately 8 inches. The platform 25 is positioned parallel above the base 51 and between the two 24″ side walls 52, having one end of two chains 26 attached to each of the 12″ shorter sides through a chain hook and loop 30 on the corners and the other end of the two chains 26 attached to each interior sides of the walls 52 near the top side through another set of chain hook and loops 30. The platform 25 is lined with additional mini-alternating air mattresses 27 all connected to the main alternating air mattress 1, the platform 25 having a plurality of fabric loops such as Velcro™ loops located on the bottom side.

(24) An electronic pulley system 29 comprises a wheel on an axle that supports movement of a cable or belt 28 along its circumference. First end of the cable 28 is attached to the midpoint of each 12″ shorter side of the platform 25 the second end of the cable 28 is attached to electronically controlled gears that rotate and counter-rotate to pull or release the cable 28 and in turn pull on or release the platform 25, the electronic pulley system 29 having programmed circuitry to determine how much force to apply and can be programmed as to how often to turn the patient. Said chains on both sides of the platform may be repositioned manually by chain hook and loops after the patient has been rotated to a new position to secure the patient. The chains are a security measure to prevent accidental falls and are not to be taut, so as to allow for automatic/programmed turning.

(25) The pulley system can also be a non-electronic pulley system that is moved by a crankshaft known in the arts.

(26) FIGS. 3 and 4 are a top view and a side view of the mattress 1 with a recessed area 2 for receiving the frame 50 and the platform 25. FIG. 5 is a side view of the platform 25, frame 50 and plastic bag 31 for waste elimination placed in the mattress's recess 2.

(27) FIG. 6 discloses a top view of the mattress with a Rotation/Waste Elimination System 100 with the frame 50 and the platform 25 placed into the recess 2 of the mattress 1. When the frame 50 and platform 25 are placed within the recessed area 2, there is a continuous surface from the mattress 1 to the mini mattresses 27 on the platform.

(28) In one embodiment, the mattress 1 is an alternating pressure mattress known in the art. An alternating pressure mattress comprising a plurality of inflatable side formations, located on both sides of the mattress, which can be inflated and deflated cyclically in a predetermined sequence. In a second embodiment, the mattress is a regular mattress with a recess area with the mini-mattresses made of similar material or foam.

(29) In the first and second embodiment, the electronic lift system or electronic pulley system rotates the lower half of the patient; the upper body may or may not have to be moved manually as determined by the degree of rotation. This allows for a more cost effective/economically feasible rotation/waste disposal system for lower-income nursing homes and caretakers in-home.

(30) In a third embodiment the mattress is a lateral rotation therapy mattress with a hole around the patient's pelvic area for waste disposal. The lateral rotation therapy mattress is known in the art. (See U.S. Pat. No. 5,375,273, “Lateral rotation therapy mattress system and method”, publication date Dec. 27, 1994, the disclosure of which is incorporated herein by reference). The lateral rotation therapy mattress includes: a plurality of side-by-side longitudinal air cells; and apparatus to supply pressurized air to the air cells to control the levels of pressure in individual ones of and/or groups of the air cells. The lateral rotation therapy mattress may have air cells divided into four groups: 1) left outer, 2) left inner, 3) right inner, and 4) right outer. Each air cell may be constructed of any suitable material such as compliant vinyl or urethane infused Nylon material. As an example, a patient may be laterally rotated about 30-45 degrees to the right by reducing the pressure in the right inner cells and increasing the pressure in the left inner cells. When it is desired to rotate the patient back to a supine position, the pressure in the right inner air cells are increased while the pressure in the left inner air cells are decreased until the pressure of both the right inner air cells and the left inner air cells are the same. When it is desired to rotate the patient to the left, the pressure in the right inner air cells are increased while the pressure in the left inner air cells are decreased. The rate of rotation is very slow and gentle so as not to wake the patient. The pressure control system for air support structure includes an air blower which supplies pressurized air to a main manifold which, in turn, provides air to air cells through a pressure regulator.

(31) With reference to FIG. 7, there is shown the bottom view of the platform 25 showing fabric loops 33 attached to each of the bottom 4 sides and the cut-out portion of the platform 34, in which the waste collecting plastic bag 31 will be placed.

(32) FIG. 8 shows the one-time use waste collecting plastic bag having dimensions which should be an exact fit to the interior cut out 34 portion of the platform 25, with each corner cut down approximately 4″ (or more) at the crease to separate the sides, fabric hooks 32 are located on the top 2″ of the outside of each side of the plastic bag 31, the plastic bag 31 is inserted into the interior cut out 34 portion of the platform 25 with the plastic bag 31 sides folded over the mini air mattresses 27 and then having the top 2″ of the outside of each side of the plastic bag 31 folded underneath so the fabric hooks 32 on the plastic bag 31 can engage with the fabric loops 33 located on the bottom of the platform 25. The one-time use waste collecting plastic bag 31 is inexpensive to manufacture and cost effective. The waste collecting plastic bag 31 can be easily removed and disposed by detaching its fabric hook from the fabric loop located on the bottom of the platform. In an alternative design, the bag 31 may be provided with both fabric hooks 32 and fabric loop elements 32′. Fabric hook elements 32 are positioned along the end of flaps or flanges 36, while fabric loop elements 32′ are positioned at spaced locations on the outside center of the bag 31.

(33) The attaching of the bag 31 to a pelvic support member includes folding flanges or flaps 36 over and around a portion of the pelvic support member so that terminal portions of the flanges or flaps are located below the pelvic support member and so that the fabric hook elements 32 are aligned with and overlap the fabric loop elements 32′. The attaching of the bag 31 to the pelvic support member further includes coupling hook and loop fasteners 32 and 32′ to one another. Bag 31 is removed from the pelvic support member upon a deposition of human waste into the receptacle portion of the bag, the removing of the bag including uncoupling hook and loop fasteners 32 and 32′ from one another and unfolding the flanges or flaps 36 from the portion of the pelvic support member.

(34) FIG. 9 shows the platform and patient tilted between 30 degrees to 40 degrees. A method for ease of rotation and waste disposal for bedridden patients to prevent and treat bedsores comprises steps of: (a) providing a mattress with a rotation/waste elimination system around the pelvic area of a patient. The mattress mentioned here is the mattress described earlier; (b) an electronic lift system supported by two pairs of sliding posts which raise one end and simultaneously lowers the opposite end of the platform to the right (or left) and turns the patient's body towards the left (or right); (c) if chains are used, manually repositioning the chain hook and loop to ensure the patient is secure, but confirming they are not taut to allow for automatic programmed turning; and (d) if necessary, manually turning the patient's upper body towards the left (or right).

(35) FIG. 10 shows the platform and patient tilted between 30 degrees to 40 degrees. A method for ease of rotation and waste disposal for bedridden patients to prevent and treat bedsores comprises steps of: (a) providing a mattress with a rotation/waste elimination system around the pelvic area of a patient.

(36) The mattress mentioned here is the mattress described earlier; (b) an electronic pulley system to pull the right cable (or left cable), in turn pulling the right (or left) side of the platform up to the right (or left) and turning the patient's body towards the left (or right); (c) manually repositioning the chains' hooks and loops to ensure the patient is secure, but confirming the chains are not taut to allow for automatic programmed turning; and (d) if necessary, manually turning the patient's upper body towards the left (or right).

(37) As depicted in FIG. 11, a personal support member or specifically a pelvic support member 102 in the form of a flexible sling utilizable in substitution for platform 25 described above comprises a flexible frame 104 including flexible two longitudinal edge elements 106a and 106b extending parallel to a long axis 108 of the sling and defining long edges thereof. Frame 104 further includes two flexible transverse edge elements 110a and 110b extending transversely to the long axis 108 of the sling and defining short edges thereof, each of the longitudinal edge elements 106a and 106b being connected to each of the transverse edge elements 110a and 110b. Plural flexible longitudinal inside elements 112 are provided each slidably connected at opposite ends to the transverse edge elements 110a and 100b, while multiple flexible transverse inside elements 114 are additionally included each slidably connected at opposite ends to the longitudinal edge elements 106a and 106b. More particularly, longitudinal inside elements 112 are provided with terminal loops 116 and 118 that extend around transverse edge elements 110a and 110b. Transverse inside elements 114 are similarly formed with terminal loops 120 and 122 that extend around longitudinal edge elements 106a and 106b. Transverse edge elements 110a and 110b traverse loops 116 and 118, while longitudinal edge elements 106a and 106b traverse loops 120 and 122. Owing to the slidable fastening of longitudinal inside elements 112 to transverse edge elements 110a and 110b, indicated by double-headed arrows 150, the longitudinal inside elements are spaced at variable distances from each other. Likewise, owing to the slidable fastening of transverse inside elements 114 to longitudinal edge elements 106a and 106b, indicated by double-headed arrows 152, the transverse inside elements are spaced at variable distances from each other.

(38) Longitudinal edge elements 106a and 106b, transverse edge elements 110a and 110b, as well as longitudinal inside elements 112 and transverse inside elements 114, are all preferably made of a fabric material. Terminal loops 116, 118, 120, 122 are formed by folding back end portions of longitudinal inside elements 112 and transverse inside elements 114 and stitching the folded-over ends to the respective inside elements.

(39) Longitudinal inside elements 112 and transverse inside elements 114 collectively define a typically irregular rectangular array of rectangular openings 124 that may be individually enlarged, by the sliding of transverse inside elements 114 along longitudinal edge elements 106a and 106b and by the sliding of longitudinal inside elements 112 along transverse edge elements 110a and 110b, to generate openings at selected locations of sufficient size to accommodate bedsores of a bedridden person, so that the bedsores are free of engagement with the supporting elements 112 and 114 and thereby are free of compressive pressure, thereby allowing adequate blood circulation and air contact for drying and healing.

(40) Where transverse inside elements 114 are primary transverse inside elements all having a first common length L1, the sling 102 may further comprise a plurality of secondary transverse inside elements 126 and 128 having a second common length L2 shorter than the length L1 of the primary transverse elements 114. Each of the secondary transverse inside elements 126, 128 is connected at one end to one of the longitudinal edge elements 106a or 106b and at an opposite end to one of the longitudinal inside elements 112, thereby providing an aperture 130 in the sling member.

(41) Optionally, longitudinal inside elements 112 are primary longitudinal inside elements all having a third common length L3, while the sling further comprises a plurality of secondary longitudinal inside elements 132 and 134 having a fourth common length L4 shorter than length L3. Each secondary longitudinal inside element 132 and 134 is connected at one end to one of the transverse edge elements 110a or 110b and at an opposite end to one of the transverse inside elements 114 at the aperture 130 in the sling member. Preferably, however, the secondary longitudinal inside elements are omitted to enable a sideways adjustment in the location of the waste-elimination aperture.

(42) Sling 102 may further comprise a receptacle 136, e.g., plastic bag, removably attachable to the sling and disposable in part below the aperture for receiving eliminated waste of the user. The removal attachment of receptacle 136 to sling 102 at aperture 130 may be implemented as discussed hereinabove with reference to bag 31 and hook and loop fasteners 32. The receptacle or bag 136 may include a plurality of tongues or flaps 137 provided with hook and loop fasteners (not shown) for removably attaching the bag to inside elements 112 and 114 defining aperture 130, as depicted in FIG. 11.

(43) Sling 102 further comprises a pair of end bars or rods or PVC pipe sections 138 and 140 made of rigid material such as metal or hard polymer. Bars or rods 138 and 140 are connected to transverse edge elements 110a and 110b via straps, loops, hooks, rivets, or other fasteners 142, 144. Each bar or rod 138 and 140 is provided with coupling members 146 such as hooks, ties, chains, cables, etc., for suspending the sling 102 from frame 50 or other uprights or posts placed alongside a bed. Bars or rods 140 serve in part to maintain the extension or spread of sling 102, preventing collapse or bunching thereof.

(44) In another embodiment, the transverse edge elements are extended by casings made of fabric and connected to transverse edge elements 110a and 110b via straps, loops, hooks, rivets, or other fasteners. The casings provide sleeves for placement of hollow plastic PVC pipes which are removable when washing the net. The PVC pipes keep the net flat and provide openings for a hammock strap to be inserted on each side to connect the sling to the tilting mechanism.

(45) It is contemplated that the tilting is effectuated periodically. The user may be tilted to one side for a fixed period of time, say, fifteen minutes, and then the tilting mechanism elevates a low side and lowers a high side of the pelvic support to tilt the user in the opposite direction. The tilting mechanism can take any form suitable for the task, including electric linear servos, electric linear actuators, electric motors with rack-and-pinion or gear-and-pulley transmission trains, hydraulic or pneumatic lifts, etc. A controller (not shown) includes an automatic timer which is possibly programmable to enable the institution of multiple tilt angles for respective time periods. In addition, the program may allow for a periodic rocking from side to side.

(46) It is to be noted that sling 102 may be used to support other parts of a user's body, for instance, the shoulder region, where bedsores are apt to arise. The main use, however, is in the pelvic region.

(47) FIG. 12 shows a patient support system including personal support member or sling 102. Support of sling 102 is suspended at opposite ends from two posts 154 and 156 which incorporate a tilting mechanism (such as electric linear servos or electric linear actuators) which is operatively connected to the sling and configured to shift the sling so as to rotate or tilt the pelvic region of a user USR. The two posts 154 and 156 are positioned on the floor on each long side of a mattress or bed 164 near a recessed portion (not shown) of the mattress. The pelvic support member or sling 102 is suspended between the two posts 154 and 156 so as to be aligned with the mattress and the user USR for support of the user's pelvic region. Each post includes a lower portion or base 158 and a top portion 160, where the top portion is slightly larger than lower portion 158 to allow the top portion to slide down over the base (as indicated by dual-headed arrow 162) for transporting a patient off bed or mattress 164. As discussed above, receptacle 136 (FIG. 11) is removably attachable to the sling 102 and disposable in part below aperture 130 (FIG. 11) for receiving eliminated waste of the user USR.

(48) Set forth below is a table that shows a feature name or descriptive label and a related reference designation or number and indicates within which figures the feature appears. FIGS. 11 and 12 and their related reference numerals are omitted from the table.
