Abstract

A person-support structure includes a control system, an input configured to communicate a first input signal to the control system, and a sensor configured to sense a physiological characteristic of a person supported on the person-support structure. The sensor communicates a second input signal corresponding to the physiological characteristic to the control system. The control system calculates a condition score as a function of the first input signal and the physiological characteristic of the person and compares the condition score to a predetermined threshold. The control system scales at least one of the physiological characteristic of the person and the predetermined threshold as a function of the first input signal.

Claims

1. A person-support structure comprising

a control system,

an input configured to communicate a first input signal to the control system,

a sensor configured to sense a physiological characteristic of a person supported on the person-support structure and communicate a second input signal corresponding to the physiological characteristic to the control system,

the control system configured to calculate a condition score as a function of the first input signal and the physiological characteristic of the person and compare the condition score to a predetermined threshold, the control system further configured to cause an alert signal to be output when the condition score is greater than the predetermined threshold, wherein the control system scales at least one of the physiological characteristic of the person and the predetermined threshold as a function of the first input signal, wherein the person-support structure includes a bed frame having an upper frame movably supported above a lower frame and the input includes a second sensor coupled to the bed frame and configured to sense a status of the bed frame, the first input signal including information corresponding to the status of the bed frame.

2. The person-support structure of claim 1, wherein the input further comprises a user interface configured to receive a user input, the first input signal including information relating to the user input.

3. The person-support structure of claim 1, wherein the person-support structure includes a person-support surface and the input includes a third sensor coupled to the person-support surface and configured to sense a status of the person-support surface, the first input signal including person-support surface status information.

4. The person-support structure of claim 3, wherein the status of the person-support surface includes at least one of a pressure in a fluid bladder of the person-support surface, a status of a surface therapy, a status of a low-air loss therapy, a status of a percussion vibration therapy, a status of a lateral rotation therapy, a status of an alternating pressure therapy, a status of a surface zone, a status of a surface function, a status of a surface length extension function, a status of a surface length reduction function, a status of a surface width extension function, a status of a surface width reduction function, a status of a turn assist function, a position of a person on the person-support surface, and a morphology of a person on the person-support surface.

5. The person-support structure of claim 1, wherein the first input signal includes information corresponding to the history of a person.

6. The person-support structure of claim 5, wherein the history of the person includes at least one of a preference of a person, a tendency of a person, an electronic medical record (EMR) of a person, a pressure ulcer risk assessment of a person, a medical history of a person, an allergy of a person, a medical condition of a person, a diagnosis of a person, a medication chart for a person, a caregiver assignment history for a person, and a habit of a person.

7. The person-support structure of claim 1, wherein the status of the bed frame includes at least one of a height of the upper frame, an angle at which a section of a deck movably coupled to the upper frame is with respect to the upper frame, a position of a siderail, at least one of a Trendelenburg position and reverse Trendelenburg position, a CPR function status, a center of gravity of a person on the bed frame, a position of the person on the bed frame, and a status of a person-support alarm.

8. The patient-support structure of claim 1, wherein the control system is configured to communicate with a remote system.

9. The patient-support structure of claim 8, wherein the remote system comprises a nurse call system.

10. A person-support structure comprising

a control system,

an input configured to communicate a first input signal to the control system,

a sensor configured to sense a physiological characteristic of a person supported on the person-support structure and communicate a second input signal corresponding to the physiological characteristic to the control system,

the control system configured to calculate a condition score as a function of the first input signal and the physiological characteristic of the person and compare the condition score to a predetermined threshold, the control system further configured to cause an alert signal to be output when the condition score is greater than the predetermined threshold, wherein the control system scales at least one of the physiological characteristic of the person and the predetermined threshold as a function of the first input signal, wherein the first input signal includes information corresponding to a characteristic of a care facility.

11. The person-support structure of claim 10, wherein the characteristic of the care facility includes at least one of a staffing level of the care facility, at least one of a date and a time of day, an amount of people in the care facility, a size of the care facility, a location of a caregiver within the care facility, a progress of a caregiver on their rounds, and an acuity of people in the care facility.

12. The person-support structure of claim 10, wherein the person-support structure includes a bed frame having an upper frame movably supported above a lower frame and the input includes a second sensor coupled to the bed frame and configured to sense a status of the bed frame, the first input signal including information corresponding to the status of the bed frame.

13. The person-support structure of claim 12, wherein the status of the bed frame includes at least one of a height of the upper frame, an angle at which a section of a deck movably coupled to the upper frame is with respect to the upper frame, a position of a siderail, at least one of a Trendelenburg position and reverse Trendelenburg position, a CPR function status, a center of gravity of a person on the bed frame, a position of the person on the bed frame, and a status of a person-support alarm.

14. The person-support structure of claim 10, wherein the input further comprises a user interface configured to receive a user input, the first input signal including information relating to the user input.

15. The person-support structure of claim 10, wherein the person-support structure includes a person-support surface and the input includes a second sensor coupled to the person-support surface and configured to sense a status of the person-support surface, the first input signal including person-support surface status information.
