Abstract

The claim over prior art is for an approach to an electronically controlled or electronically monitored breathing system that represents an improvement in electrical reliability, manufacturing cost and efficiency, user maintenance, system reliability, user cost and maintenance. These improvements are accomplished by placing the major electronic, mechanical and electromechanical control elements and sensor components in a single replaceable module.

Claims

1. A modular, self-contained, removable control subsystem for a breathing device comprising a microcontroller, measurement electronics, input/output cabling, connectors, gas control solenoids, gas connections, and software for the purpose of controlling gas addition to the breathing device.

2. The modular control system of claim 1 comprising a low pressure Oxygen measurement subsystem.

3. The modular control system of claim 1 comprising a mid (intra-stage) pressure Oxygen measurement subsystem.

4. The modular control system of claim 1 comprising a high pressure gas measurement subsystem.

5. The modular control system of claim 1 comprising a system power supply.

6. The modular control system of claim 1 comprising a Barometric sensor(s) and a pressure sensing measurement subsystem.

7. The modular control system of claim 1 comprising wireless transceiver(s) to communicate data to and from the breathing system measurement devices.

8. The modular control system of claim 1 comprising a wireless transceiver(s) to communicate data between the module and display/input devices.

9. The modular control system of claim 1 comprising a Personal Alert Safety System (PASS) subsystem.
