Abstract

A patient support apparatus includes a sensor capable of detecting vital signs, setting acceptable limits for the vital signs, and includes structures for monitoring the vital signs and providing local and/or remote indications to caregivers if the vital signs fall outside of acceptable limits.

First claim

The invention claimed is:

1. A detection and notification system for a patient support apparatus comprising:
a sensor detecting a vital sign of a patient without contacting the patient, the sensor positioned on and secured to a movable deck section of the patient support apparatus by a mechanical isolation structure preventing mechanical vibrations in the patient support apparatus from being transferred to the sensor;
a controller operable to receive a signal from the sensor indicative of the vital sign of the patient, the controller operable to compare the vital sign to pre-established limits to determine whether the vital sign is within an acceptable range; and
a first notification system operable to respond to commands from the controller to provide an indication as to whether the vital sign is within the acceptable range or an alarm condition exists,
wherein the alarm condition indicating that the vital sign is outside of the acceptable range, provide a visual indication of a deviation from the acceptable range by illuminating a first iconic representation of the vital sign in a first manner, and
if the vital sign does not deviate from the acceptable range for the vital sign, provide the visual indication by illuminating the first iconic representation in a second manner.

2. The detection and notification system of claim 1 , wherein the sensor simultaneously detects a first vital sign and a second vital sign.

3. The detection and notification system of claim 1 , wherein the detection and notification system includes a plurality of sensors simultaneously detecting the vital sign of the patient.

4. The detection and notification system of claim 3 , wherein each of the plurality of sensors detects both a first vital sign and a second vital sign.

5. The detection and notification system of claim 4 , wherein the controller is operable to receive a first signal indicative of a position of the patient supported on the patient support apparatus, the controller operable to utilize the position of the patient to determine whether to disregard an information of the vital sign from one of the plurality of sensors.

6. The detection and notification system of claim 5 , wherein the controller is operable to prompt a user to suspend operation of the first notification system based on the position of the patient.

7. The detection and notification system of claim 1 , wherein the controller is operable to receive a first signal indicative of a position of the patient supported on the patient support apparatus, and further operable to prompt a user to suspend operation of the first notification system based on the position of the patient.

8. The detection and notification system of claim 7 , wherein the controller is operable to receive a second signal indicative of a position of a component of the patient support apparatus and to determine the acceptable range of the vital sign based, at least in part, on the position of the component of the patient support apparatus.

9. The detection and notification system of claim 8 , wherein the controller is operable to communicate with an electronic medical record system to receive information from the electronic medical record system indicative of a medical history of the patient supported on the patient support apparatus and to determine the acceptable range of the vital sign based, at least in part, on the medical history of the patient.

10. The detection and notification system of claim 9 , wherein the controller is operable to utilize the medical history of the patient supported on the patient support apparatus to perform an algorithm that analyzes the vital sign to determine that the patient is to experience an adverse event and to provide a notification discernible by a user that the adverse event has reached a threshold.

11. A patient support apparatus comprising:
at least one sensor, the at least one sensor positioned on and secured to a frame member of the patient support apparatus by a mechanical isolation structure preventing mechanical vibrations in the patient support apparatus from being transferred to the at least one sensor, the at least one sensor operable to provide a signal indicative of a vital sign of a patient supported on the patient support apparatus without contacting the patient, and
a notification system coupled to the at least one sensor, the notification system operable to process the signal from the at least one sensor which provide an indication of the vital sign to determine the vital sign, compare the vital sign determined by the notification system by processing the signal from the at least one sensor to a predefined acceptable limit, and, if the vital sign determined by the notification system by processing the signal from the at least one sensor deviates from the predefined acceptable limit, provide a visual indication of the deviation by illuminating a first iconic representation of the vital sign in a first manner, and if the vital sign does not deviate from the predefined acceptable limit for the vital sign, provide the visual indication by illuminating the first iconic representation of the vital sign in a second manner.

12. The patient support apparatus of claim 11 , wherein the notification system is operable to project the first iconic representation to a surface spaced apart from the patient support apparatus.

13. The patient support apparatus of claim 12 , wherein the first iconic representation is simultaneously illuminated on a first surface of the patient support apparatus and projected onto the surface spaced apart from the patient support apparatus.

14. The patient support apparatus of claim 13 , wherein the first iconic representation is projected to the surface spaced apart from the patient support apparatus by a projector located on the patient support apparatus.

15. The patient support apparatus of claim 14 , wherein said illuminating the first iconic representation in the first manner comprises illuminating the first iconic representation in a first color and said illuminating the first iconic representation in the second manner comprises illuminating the first iconic representation in a second color.

16. The patient support apparatus of claim 15 , wherein said providing the visual indication of the deviation includes simultaneously illuminating the first iconic representation on the first surface of the patient support apparatus in the first color and projecting the first iconic representation on the surface spaced apart from the patient support apparatus in the first color.

17. The patient support apparatus of claim 16 , wherein said providing the visual indication that the vital sign determined by the notification system by processing the signal from the at least one sensor does not deviate from the predefined acceptable limit for the vital sign determined by the notification system by processing the signal from the at least one sensor includes simultaneously illuminating the first iconic representation on the first surface of the patient support apparatus in the second color and projecting the first iconic representation on the surface spaced apart from the patient support apparatus in the second color.

18. The patient support apparatus of claim 11 , wherein said providing the visual indication of the deviation includes simultaneously illuminating the first iconic representation on a first surface of the patient support apparatus in a first color and projecting the first iconic representation on a surface spaced apart from the patient support apparatus in the first color.
