DETAILED DESCRIPTION

(10) Referring to FIG. 1, a patient support apparatus 10 is illustratively embodied as a hospital bed 10. The hospital bed 10 includes a frame 12, a mattress 14 supported on the frame 12, and a detection and notification system 16. An example of a suitable frame 12 and mattress 14 is shown and described in U.S. Patent Pub. No. 2018/0184984 which is expressly incorporated by reference herein for the purpose of describing the frame 12 and mattress 14 along with associated functions and capabilities of the frame 12 and mattress 14. The detection and notification system 16 is configured to determine an incontinence state of a patient resting on the mattress 14 and display selectively notifications that indicate various statuses of the detection and notification system 16.

(11) The detection and notification system includes a condition-responsive sensor 18, a controller 20 coupled to the sensor 18, and an external alarm system 22 as shown diagrammatically in FIG. 1. The sensor 18 is configured to sense the presence of moisture on the patient and/or the mattress 14 and output signals indicative thereof. The controller 20 receives the signals from the sensor 18 and issues commands to the external alarm system 22 to provide a notification based on user inputs and/or user preferences stored in the controller 20. The external alarm system 22 provides one or more notifications that match the stored inputs or preferences.

(12) In the illustrative embodiment, the sensor 18 is integrated into an incontinence detection pad 24 that is supported on the mattress 14 and the frame 12 as suggested in FIG. 1. The incontinence detection pad 24 is positioned on the hospital bed 10 for surveillance for unwanted incontinence fluids or other biofluids that may be produced by a patient. The incontinence detection pad 24 absorbs and retains the fluids therein and the incontinence detection pad 24 may be removed and replaced without replacing the entire mattress 14. An example of a suitable incontinence detection pad 24 is shown and described in U.S. Patent Pub. No. 2019/0060137 which is expressly incorporated by reference herein for the purpose of describing a suitable incontinence detection pad.

(13) The condition-responsive sensor 18 includes a sensor circuit with a plurality of electrically conductive traces printed on a substrate of the incontinence detection pad 24 that produce the sensor signals when moisture is present on the incontinence detection pad 24. Examples of a suitable sensor with a sensor circuit integrated into an incontinence detection pad is shown and described in U.S. Patent Pub. Nos. 2017/0065464 and 2018/0021184, each of which is expressly incorporated herein for the purpose of showing and describing a suitable sensor for an incontinence detection pad and means for powering the sensor and transmitting the signals produced by the sensor. In some embodiments, the sensor 18 communicated wirelessly with controller 20. In other embodiments, a wired connection is provided between sensor 18 and controller 20.

(14) The controller 20 includes a processor 26 and a memory device 28 storing instructions that, when executed, cause the external alarm system 22 to display selectively the notifications according to the user inputs. The controller 20 includes all of the functionality needed to operate the external alarm system 22 and is coupled with a graphical user interface 30 mounted on or near the hospital bed 10 as shown in FIG. 1. The user inputs are entered by a caregiver with the graphical user interface 30 and are stored in memory device 28 to program the controller 20 to operate the external alarm system 22 according to the caregiver's and/or patient's preferences.

(15) The external alarm system 22 displays notifications that represent statuses of the sensor 18 based on the user inputs that have been entered into the user interface 30 and stored in the memory device 28 of the controller 20. In one embodiment, the status of the sensor 18 is whether or not moisture is present on the incontinence detection pad 24. In another embodiment, the status of the sensor 18 is whether or not the hospital bed 10 is provided with an incontinence fluid sensing capability (i.e. the incontinence detection pad 24 with the integrated sensor 18).

(16) The external alarm system 22 includes a first indicator 32 located in a proximate location to the hospital bed 10 and a second indicator 34 located in a remote location out of view from the hospital bed 10. The proximate location may be in the same room as the hospital bed 10 while the remote location is outside of the room with the hospital bed 10. The controller 20 may be coupled with the external alarm system 22 through a suitable connection, such as a universal asynchronous receiver/transmitter (UART) connection 36, or through a wireless connection 38 that includes one or more antennas 40 and/or transceivers 42. The first indicator 32 displays iconic representations on or near the hospital bed 10. Depending on the user inputs entered into the user interface 30, the first indicator 32 may display an iconic representation indicative of whether or not moisture is present on incontinence detection pad 24, or an iconic representation indicative of whether or not the patient's hospital bed 10 is currently provided with an incontinence detection pad 24. The second indicator 34 may display the same representations at the remote location or different representations depending on the user inputs entered into the user interface 30. In the illustrative embodiment, the second indicator 34 is located at a master nurse call station.

(17) When a status of the sensor 18 changes, the first and the second indicators may display a new iconic representation to alert the caregiver of the change and indicate that appropriate action may be needed such as, for example, changing a wet or soiled incontinence detection pad 24. In some instances, changing a wet or soiled incontinence detection pad is not an action that requires urgent completion and medical personnel made be delayed in responding to the action if they are busy with other patients. Still, the sensor 18 within the incontinence detection pad 24 is configured to provide the signals as soon as moisture is detected on the incontinence detection pad 24. Upon receiving the signals from the sensor 18, the controller 20 may cause the first indicator 32 to display the new iconic representation proximate to the hospital bed 10 as soon as the sensor 18 detects the moisture. Non-medical personnel within the room may see the new iconic representation and expect urgent action to remedy the situation even though urgent action may not be needed and/or possible at that time. Accordingly, the non-medical personnel may become irritated or upset that the patient's incontinence detection pad 24 has not been changed. The external alarm system 22 in the illustrative embodiment may be programmed selectively through the user inputs into the user interface 30 to either: 1) turn off the first indicator 32 such that only the second indicator 34 is used; 2) display an iconic representation with the first indicator 32 that indicates only that the hospital bed 10 is currently provided with an incontinence detection pad 24; or 3) change selectively what types of indications are provided by the first indicator 32.

(18) In the illustrative embodiment, the first indicator 32 is mounted to a foot end 44 of the hospital bed 10 and includes an indicator panel 46 and a projector 48 as shown in FIG. 1. The indicator panel 46 displays a plurality of iconic representations 50 associated with different features of the hospital bed 10 and/or information related to the patient. The projector 48 illuminates iconic representations 52 on a surface 54 that is spaced apart from the hospital bed 10. The iconic representations 52 illuminated by the projector 48 are substantially similar to the iconic representations 50 displayed by the indicator panel 46; however, in other embodiments, they may be different. In the illustrative embodiment, the surface 54 is the floor near the foot end 44 of the hospital bed 10; however, the surface 54 may be a wall or another surface located proximate to the hospital bed 10. An example of a suitable indicator panel and projector is described in U.S. Patent Pub. No. 2018/0184984, which is already incorporated by reference herein and may also be used for the purpose of describing a suitable indicator panel capable of displaying the iconic representations and a suitable projector capable of illuminating the iconic representations.

(19) In the illustrative embodiment, one such iconic representation displayed by the indicator panel 46 and illuminated by the projector 48 is a water droplet 56 as shown in FIG. 1. The water droplet 56 is associated with the sensor 18 in the incontinence detection pad 24. The controller 20 displays the water droplet 56 on the indicator panel 46 and/or illuminates the water droplet using the projector depending on the user inputs entered into the user interface 30. In one embodiment, the controller 20 causes the water droplet 56 to change colors as the status of the sensor 18 in the incontinence detection pad 24 changes. In the illustrative embodiment, the controller 20 causes first indicator to display and/or illuminate the water droplet 56 with a white color when the hospital bed 10 is not provided with an incontinence detection pad 24. The controller 20 causes the first indicator 32 to display and/or illuminate the water droplet 56 with a green color when an incontinence detection pad 24 is provided in the hospital bed 10. In other embodiments, other colors may be used to indicate the presence or lack of an incontinence detection pad 24 on the hospital bed 10.

(20) In one embodiment, the green color indicates a lack of moisture on the incontinence detection pad 24 as determined by the sensor 18. Once the sensor 18 detects moisture on the incontinence detection pad 24, a signal is output to the controller 20 and the controller 20, upon receipt of the signal, causes the first indicator 32 to display and/or illuminate the water droplet 56 with an amber color to notify a caregiver that action is needed. In other embodiments, any suitable color may be used to indicate the presence of moisture on the incontinence detection pad 24 and that action is needed. The controller 20 also causes the second indicator 34 to notify the caregiver at the remote location that action is needed. The second indicator 34 may display and/or illuminate a similar iconic representation to the water droplet 56 in a similar manner to first indicator 32; however, any suitable method of notifying a caregiver at the remote location may be used.

(21) In accordance with the present disclosure, the user interface 30 receives user inputs that selectively change an appearance of the iconic representations 50, 52 at the proximate location than the appearance typically displayed and/or illuminate when the sensor 18 detects moisture on the incontinence detection pad 24. In one embodiment, the user inputs program the controller 20 to cause the first indicator 32 to continue to display and/or illuminate the water droplet 56 with the green color even when moisture is present on the incontinence detection pad 24. In this instance, the green color indicates only that the hospital bed 10 has been provided with an incontinence detection pad 24. In another embodiment, the indicator panel 46 and/or the projector 48 of the first indicator 32 may be turned off such that only the second indicator 34 notifies a caregiver at the remote location when moisture is detected on the incontinence detection pad 24 by the sensor 18.

(22) Referring now to FIGS. 2-7, the graphical user interface 30 displays a touchscreen 60 that includes a number of icons which may be selected by a user to control various functions of the hospital bed 10. The functionality of the touchscreen 60 is disclosed in the PCT application WO2016/196403, filed May 29, 2016, and incorporated by reference herein for the disclosure of a touch screen menu structure of the hospital bed 10. The touchscreen 60 displays a home screen 62 that includes an alarm status section 64, an information bar 66, a function panel 68, a home key 70, and a scrolling menu 72. The scrolling menu 72 includes a settings button icon 74 which, when touched by a user, activates a settings screen 76 shown in FIG. 3.

(23) The settings screen 76 is displayed on the graphical user interface 30 when the settings button icon 74 is touched as shown in FIG. 3. The settings screen 76 includes a bed function panel 78 and a bed information panel 80. The bed function panel 78 includes a bed features button icon 82 which, when touched by the user, activates a bed features screen 84 as shown in FIG. 4.

(24) The bed features screen 84 includes a display function panel 86 as shown in FIG. 4. The display function panel 86 includes a selection button icon 88 which, when touched by the user, activates an indicator settings screen 90 as shown in FIG. 5. The selection button icon 88 depicts SAFEVIEW™, which is a proprietary term that is used to represent various functions associated with the detection and notification system 16.

(25) The indicator settings screen 90 includes an indicator button icon 92 and a projector button icon 94 that, when selected by a user, activate an incontinence indicator screen 96, as shown in FIG. 6, and a projection screen 98, as shown in FIG. 7. The indicator button icon 92 depicts WATCHCARE™, which is a proprietary term that is used to represent various functions associated with the detection and notification system 16.

(26) With the incontinence indicator screen 96 activated, the user may make a selection to alter the appearance of the first indicator 32. The incontinence indicator screen 96 includes a first indicator button icon 100, a second indicator button icon 102, and a third indicator button icon 104. The first button icon 100, when selected, programs the controller 20 to cause the first indicator 32 to display and illuminate the water droplet 56 using both the indicator panel 46 and the projector 48. The second button icon 102, when selected, programs the controller 20 to cause the first indicator to display the water droplet 56 using only the indicator panel 46. The third button icon 104, when selected, programs the controller 20 to cause the first indicator 32 to be turned off completely. Once the user is finished making a selection, an accept button icon 106 may be selected to activate the desired appearance of the first indicator 32. In the illustrative embodiment, the second indicator 34 continues to notify the caregiver regardless of the button icon selection made on the incontinence indicator screen 96; however, in other embodiments, the appearance of the notification provided at the second location by the second indicator may also be altered.

(27) With the projection screen 98 activated, the user may make additional selections to alter the appearance of the illuminated iconic representations 52 from the projector 48 as shown in FIG. 7. The projection screen 98 includes a first projector button icon 108 that, when selected, turns the floor projections on and a second projector button icon 110 that, when selected, turns the floor projections off. Once the user is finished making a selection, an accept button icon 112 may be selected to activate the desired appearance of the illuminated iconic representations 52 from the projector 48.

(28) Although certain illustrative embodiments have been described in detail above, variations and modifications exist within the scope and spirit of this disclosure as described and as defined in the following clauses and claims.
