Abstract

A room monitor having a second display includes a controller, a first display and a second display. The first display is preferably a touch screen monitor, which allows the entry of data into the controller without the need for a keyboard. However, the controller may be programmed through a keyboard. The controller includes a plurality of inputs and outputs for monitoring and/or controlling such room environmental factors as pressure, temperature, humidity and lighting. The inputs are used to read sensors. The outputs are used to actuate control devices. The first display includes a plurality of menus for controlling at least one environmental factor. The second display shows information the condition of a critical environment room. There is at least one message displayed on the second display. A second embodiment of the room monitor includes a controller and the first display. The first display must be a touch screen monitor.

Claims

1. A room monitor comprising:

a controller having at least one input and at least one output, said controller having the functions of monitoring and controlling at least one room environmental factor of pressure inside a room;

a first display being connected to said controller, said first display providing information for the at least one room environmental factor of pressure inside a room;

at least one second display being connected to said controller, said at least one second display providing at least one message concerning the condition of the room being one of infectious room, room being cleared and room cleared; and

entering a command into said controller through said first display to change the pressure inside the room, results of said command being reflected on said at least one second display through a message concerning the condition of the room, said at least one display being located adjacent said first display.

2. The room monitor of claim 1 wherein:

said at least one input being connected to at least one sensor.

3. The room monitor of claim 1 wherein:

said at least one output being connected to at least one control device for actuation thereof, said at least one control device changing the at least one room environmental factor.

4. The room monitor of claim 1 wherein:

said first display providing status on a mode of isolation, said mode being one of positive isolation, negative isolation or no isolation.

5. The room monitor of claim 1 wherein:

said first display being a touch screen monitor, said first display providing access to said controller.

6. The room monitor of claim 1, further comprising:

one of a keyboard and a keypad, one of said keyboard and keypad providing access to said controller.

7. The room monitor of claim 1 wherein:

at least one of said at least one message on said second display being active for a programmable period of time.

8. The room monitor of claim 1 wherein:

said controller being accessed to set limits for the at least one room environmental factor, if one of the limits is exceeded, an alarm is activated.

9. The room monitor of claim 1 wherein:

at least one of said at least one message having an associated color.

10. A room monitor comprising:

a controller having at least one input and at least one output, said at least one input being connected to at least one sensor, said at least one output being connected to at least one control device for actuation thereof, said at least one control device changing the at least one room environmental factor, said controller having the functions of monitoring and controlling said at least one room environmental factor of pressure inside a room;

a first display being connected to said controller, said first display providing information for the at least one room environmental factor of pressure inside a room;

at least one second display being connected to said controller, said at least one second display providing at least one message concerning the condition of the room being one of infectious room, room being cleared and room cleared; and

entering a command into said controller through said first display to change the pressure inside the room, results of said command being reflected on said at least one second display through a message concerning the condition of the room, said at least one display being located adjacent said first display.

11. The room monitor of claim 10 wherein:

at least one of said at least one message on said second display being active for a programmable period of time.

12. The room monitor of claim 10 wherein:

said controller being accessed to set limits for the at least one room environmental factor, if one of the limits is exceeded, an alarm is activated.

13. The room monitor of claim 10 wherein:

at least one of said at least one message having an associated color.

14. The room monitor of claim 10 wherein:

said first display providing status on a mode of isolation, said status being one of positive isolation, negative isolation or no isolation.
