Abstract

A medical gas alarm system for use in a healthcare facility having a medical gas system and having a network of computer devices is provided. The alarm system includes at least one area alarm controller adapted to receive a first signal indicative of a condition of a first portion of the medical gas system. The area alarm controller is adapted to communicate with the network. The alarm system also includes at least one master alarm controller adapted to receive a second signal indicative of a condition of a second portion of the medical gas system. The master alarm controller is adapted to communicate with the network. The area alarm controller is adapted to communicate with the master alarm controller through the network.

Claims

1. A medical gas alarm system for use in a healthcare facility having a medical gas system and having a network of computer devices, the medical gas alarm system comprising:

at least one area alarm controller adapted to receive a first signal indicative of a condition of a first portion of the medical gas system and adapted to communicate with the network; and

at least one master alarm controller adapted to receive a second signal indicative of a condition of a second portion of the medical gas system and adapted to communicate with the network, the at least one area alarm controller being adapted to communicate with the at least one master alarm controller through the network, and

wherein self-diagnostic tests may be run by the medical gas alarm system.

2. A medical gas alarm system according to claim 1, further comprising a plurality of sensor modules configured to sense gas pressures in respective gas pipes of the medical gas system,

wherein the area alarm controller includes a plurality of display modules, each display module being associated with a respective sensor module, and each display module being configured to display the gas pressure sensed by the respective sensor module.

3. A medical gas alarm system according to claim 2, wherein the self-diagnostic tests may be run for each of the plurality of display modules of the area alarm controller.

4. A medical gas alarm system according to claim 1, wherein the self-diagnostic tests may be run by the master alarm controller.

5. A medical gas alarm system according to claim 1, wherein the area alarm controller is adapted to couple to a first network hub of the network.

6. A medical gas alarm system according to claim 5, wherein the master alarm controller is adapted to couple to a second network hub of the network.

7. A medical gas alarm system according to claim 6, wherein the master alarm controller communicates with a server of the network through the second network hub.

8. A medical gas alarm system according to claim 6, wherein the alarm controller communicates with a server of the network through the first network hub.

9. A medical gas alarm system according to claim 6, wherein the area alarm controller communicates with the master alarm controller through the first and second network hubs.

10. A medical gas alarm system for use in a healthcare facility having a medical gas system which delivers a plurality of medical gases to a plurality of locations in the healthcare facility including source equipment through a number of lines that are routed from the source equipment to outlets located throughout the healthcare facility, and a plurality of sensor modules, the medical gas alarm system comprising:

a master alarm controller adapted to receive a plurality of alarm signals, each alarm signal being indicative of a respective alarm condition in the source equipment; and

an alarm controller adapted to receive an input signal indicative of a condition of the medical gas system, the alarm controller being adapted to couple to the network,

wherein the master alarm controller including a display screen that displays text messages identifying any alarm conditions that occur, and

wherein the plurality of sensors monitors medical gas levels of the plurality of medical gases such that when the medical gas level falls below a predetermined level of a main supply the medical gas alarm system switches to a back-up supply and contacts supplier of the medical gas.

11. A medical gas alarm system according to claim 10, wherein the master alarm controller includes buttons that are operable to program the text messages that appear on the display screen for each of the alarm conditions.

12. A medical gas alarm system according to claim 11, wherein the master alarm controller is configured to host a website that is used to program the master alarm controller with the text messages that appear on the display screen for each of the alarm conditions.

13. A medical gas alarm system according to claim 12, wherein each web page of the website is identified by a respective network address.

14. A medical gas alarm system according to claim 10, wherein the alarm controller is programmed to send an e-mail to at least one designated e-mail address to provide notification of any alarm conditions that occur.

15. A medical gas alarm system according to claim 14, wherein the alarm controller is programmed to send an e-mail to the supplier of the medical gas when the medical gas alarm system switches over to the back-up supply of medical gas.
