Patient support apparatus including a user module generating state indicators corresponding to monitored conditions and changes thereof
A patient support apparatus comprises a support structure, a user module, and a controller. The user module comprises a display and indicator panel that has a plurality of indicia, each associated with a monitored condition. First light emitters are arranged to project light to illuminate the indicia and second light emitters are arranged to project light off a reflective surface. The controller is coupled to the display and the light emitters, and is configured to, in response to a change in a state of one of the monitored conditions, generate on the display a state indicator corresponding to the change in the state and activate the light emitters such that a color of the light projected by the light emitters matches a color of the state indicator.
1. A patient support apparatus comprising:
a support structure having a patient support surface;
a user module operatively attached to the support structure and including a user interface having a display supported for viewing by a user when adjacent to the support structure;
a reflective surface coupled to the support structure and spaced from the user module;
one or more surface light emitters arranged to project light against the reflective surface to illuminate the reflective surface in a reflected color so that the reflected color is viewable by a user remote from the support structure; and
a controller coupled to the user interface and the one or more surface light emitters, the controller being configured to, in response to a change in a state of one or more monitored conditions, generate on the display a state indicator corresponding to the change in the state and activate the one or more surface light emitters to indicate the change in the state.
2. The patient support apparatus of claim 1 , further comprising at least one of a footboard and a side rail coupled to the support structure, the at least one of the footboard and the side rail having the reflective surface.
3. The patient support apparatus of claim 1 , further comprising:
an indicator panel having a plurality of indicia; and
one or more indicia light emitters supported by the user module and arranged to project light to illuminate the indicia.
4. The patient support apparatus of claim 3 , wherein the controller is further configured to, in response to the change in a state of one of the monitored conditions, activate the one or more indicia light emitters such that a color of the light projected by the one or more indicia light emitters matches a color of the light projected by the one or more surface light emitters and a color of the state indicator.
5. The patient support apparatus of claim 4 , wherein the controller is configured to, in response to the change in the state of the one of the monitored conditions, delay generating the state indicator on the display, delay activating the one or more surface light emitters, and delay activating the one or more indicia light emitters, until a predetermined period of time has elapsed after the change in the state.
6. The patient support apparatus of claim 4 , wherein the controller is configured to, in response to the change in the state of the one of the monitored conditions, intermittently generate the state indicator on the display, intermittently activate the one or more surface light emitters, and intermittently activate the one or more indicia light emitters, such that the state indicator, the light projected by the one or more surface light emitters, and the light projected by the one or more indicia light emitters are coordinated to flash at a predetermined frequency.
7. The patient support apparatus of claim 3 , wherein the indicator panel is integral with the user interface.
8. The patient support apparatus of claim 7 , further comprising a second user module coupled to the support structure, spaced from the user module, to indicate the change in the state of the one of the monitored conditions.
9. The patient support apparatus of claim 3 , wherein the indicia comprise graphical symbols associated with the monitored conditions.
10. The patient support apparatus of claim 1 , further comprising a sensor system coupled to the controller to determine current states of the monitored conditions.
11. The patient support apparatus of claim 10 , wherein the sensor system comprises one or more sensors.
12. The patient support apparatus of claim 10 , wherein the one of the monitored conditions is associated with occupancy of the patient support apparatus by a patient.
13. The patient support apparatus of claim 10 , further comprising one or more side rails coupled to the support structure; and
wherein the one of the monitored conditions is associated with a side rail position of the one or more side rails.
14. The patient support apparatus of claim 10 , wherein the support structure includes a support frame and a patient support deck having a back section capable of articulating relative to the support frame; and
wherein the one of the monitored conditions is associated with an angle of the back section relative to the support frame.
15. The patient support apparatus of claim 10 , further comprising a lift system coupled to the support structure to raise and lower the patient support surface; and
wherein the one of the monitored conditions is associated with a height of the patient support surface.
16. The patient support apparatus of claim 10 , further comprising an AC power plug configured to plug into an external power source; and
wherein the one of the monitored conditions is associated with the AC power plug.
17. The patient support apparatus of claim 10 , further comprising wheels coupled to the support structure and one or more brakes associated with the wheels; and
wherein the one of the monitored conditions is associated with the one or more brakes.
18. The patient support apparatus of claim 1 , wherein the controller is further configured to, in response to the change in a state of one of the monitored conditions, activate the one or more surface light emitters such that a color of the light projected by the one or more surface light emitters matches a color of the state indicator.
19. The patient support apparatus of claim 18 , wherein the controller is configured to, in response to the change in the state of the one of the monitored conditions, delay generating the state indicator on the display, and delay activating the one or more surface light emitters, until a predetermined period of time has elapsed after the change in the state.
20. The patient support apparatus of claim 18 , wherein the controller is configured to, in response to the change in the state of the one of the monitored conditions, intermittently generate the state indicator on the display, and intermittently activate the one or more surface light emitters, such that the state indicator and the light projected by the one or more surface light emitters are coordinated to flash at a predetermined frequency.
