Abstract

A system for pressure ulcer prophylaxis and treatment includes an annunciator which is attached to the outer face of the door or to the doorway of a patient'"'"'s room and a bedside patient position sequence indicator. The annunciator includes a timing device with settable cycle duration and provides both visual and audible signals to indicate that a prescribed patient turning regimen cycle now requires repositioning of the patient. The annunciator generates a first signal when the cycle duration enters an expiry window and generates a different, intensified signal after the cycle has ended without being reset by a caregiver. The patient position sequence indicator includes a visual display which advises a caregiver of the position in which the patient was last placed and the next sequential position to which the patient is to be moved.

Claims

1. A system for pressure ulcer prophylaxis and treatment of a bedridden patient within a room, the system comprising an annunciator, the annunciator including a patient repositioning cycle timer, the cycle timer being resettable by a caregiver, the annunciator further including a caregiver attention directing device operatively coupled to the cycle timer, the caregiver attention directing device notifying the caregiver that the patient'"'"'s position should be changed in response to a signal received from the cycle timer, the cycle timer generating the signal after a predetermined time interval relative to resetting the cycle timer, the annunciator being positioned externally of the room adjacent a doorway to the room, the system further including a patient position sequence indicator within the room and adjacent the patient, the patient position sequence indicator being preprogrammed with prescribed sequential patient turning positions, the patient position sequence indicator including a visual display of patient positions, the patient position sequence indicator being accessed by the caregiver to indicate the next sequential position to which the patient is to be placed by the caregiver after the caregiver receives notification from the attention directing device.

2. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the caregiver attention directing device comprises a visual indicator.

3. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the caregiver attention directing device comprises a sound generator.

4. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the cycle enters an expiry window after the predetermined time interval relative to resetting the cycle timer.

5. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the predetermined time interval relative to resetting the cycle timer comprises expiration of the cycle.

6. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein a plurality of caregiver attention directing devices are provided and the cycle timer generates a plurality of signals at different predetermined time intervals relative to resetting the cycle timer, each attention directing device being operatively coupled to the cycle timer and being actuated responsive to a dedicated one of the plurality of signals.

7. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1, the annunciator further including programming means for establishing the duration of a cycle, the programming means being operatively coupled to the cycle timer.

8. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the cycle timer comprises a pulse generator operatively coupled to a counter, the counter generating the signal received by the attention directing device.

9. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the cycle timer comprises a processor.

10. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the cycle timer is resettable by the caregiver only after the predetermined time interval has passed.

11. A system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 1 wherein the annunciator is self-contained within a single housing.

12. In a healthcare environment wherein a bedridden patient is situate in a room having a doorway, the improvement comprising an annunciator positioned exteriorly of the room adjacent or at the doorway in an area frequented by a patient caregiver, the annunciator being self-contained within a housing, the annunciator including a cycle timer, a caregiver actuated switch being operatively coupled to the cycle timer, the cycle timer being resettable by the caregiver actuated switch, the annunciator further including a caregiver attention directing device operatively coupled to the cycle timer, the cycle timer generating a signal after a predetermined time interval relative to resetting the cycle timer, the caregiver attention directing device receiving the cycle timer signal and in response thereto, generating an attention directing signal which notifies the caregiver to administer to the patient a prescribed treatment, the cycle timer being unresponsive to the caregiver actuated switch prior to completion of the predetermined time interval.

13. The improvement as constructed in accordance with claim 12 further including visual indicia within the room and adjacent the patient'"'"'s bed, the visual indicia being representative of the treatment to be provided by the caregiver in response to the attention directing signal.

14. An annunciator as constructed in accordance with claim 12 wherein the cycle timer is unresponsive to the caregiver actuated switch unless the switch remains continuously actuated for a predetermined period.

15. An annunciator as constructed in accordance with claim 12 wherein the cycle tinier comprises a pulse generating circuit operatively connected to a counter circuit, the counter circuit generating the cycle timer signal.

16. In a healthcare environment wherein a bedridden patient is situate in a room having a doorway, the improvement comprising a system for pressure ulcer prophylaxis and treatment, the system including an annunciator positioned adjacent or at a doorway in an area frequented by a patient caregiver, the annunciator including a cycle timer, a caregiver actuated switch and a caregiver attention directing device, the caregiver actuated switch and the attention directing device being operatively coupled to the cycle timer, the system further including a patient position sequence indicator within the room and in proximity to the patient, the patient position sequence indicator including a visual display of sequential patient positions, the patient position sequence indicator being preprogrammed with an order of patient positions to be sequentially displayed, the patient position sequence indicator further including a caregiver actuated switch, the patient position sequence indicator sequentially advancing the visual display of patient positions to the next preprogrammed patient position in response to the actuation of the caregiver actuated switch.

17. The system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 16 wherein the patient position sequence indicator advances the display of patient positions only when the caregiver actuated switch remains continuously actuated for a predetermined period.

18. The system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 17 wherein the patient position sequence indicator displays the current patient position in response to the actuation of the caregiver actuated switch for a duration less than the predetermined period.

19. The system for pressure ulcer prophylaxis and treatment as constructed in accordance with claim 16 wherein the patient position sequence indicator advances the display of patient positions in response to actuation of the caregiver actuated switch only after a predetermined time interval relative to the preceding advancement of the displayed patient position.
