Portable medical gas delivery system

Abstract

An apparatus for producing gas for use in medical applications. The apparatus includes a compressed gas unit having at least one container of compressed gas and a solenoid valve. An adjustable pressure regulator communicably connected to the gas container, separate and distinct from the solenoid valve, is adjusted to control the pressure of the gas provided from the container to tire solenoid valve An electrical power source Is connected to the solenoid valve. A pressure activated electronic switch connected to the power source is responsive to a selected amount of voluntary fingertip, pressure for opening the solenoid valve to transmit the gas therethrough to a conduit, which further transmits the gas to a destination for use or storage.

         17 . An apparatus for dispensing medical grade gas, said apparatus comprising:
 a portable compressed gas unit including:
 a housing including a cylinder cartridge puncture valve adapted for attachment to a source of compressed gas, 
 a solenoid communicably connected to the source of compressed gas, the solenoid including an inlet and an outlet, 
 a pressure adjustable gas regulator separate and distinct from the solenoid and communicably interconnected between the source of compressed gas and the inlet of the solenoid for selectively adjusting the pressure of the gas provided from the source of compressed gas to the solenoid, the gas regulator including a regulator adjustment knob to provide a selected level of pressure, 
 a pressure gauge connected between the gas regulator and the solenoid, and 
 a pressure activated electric switch engaged to selectively open the solenoid; and 
   a conduit communicably attached to the outlet of the solenoid for transmitting gas to a destination for storage or use in a medical application when the solenoid is opened by operation of the pressure activated electric switch.   
     
     
         18 . The apparatus of  claim 17  wherein the compressed gas includes at least one of carbon dioxide, atmospheric air, helium and oxygen. 
     
     
         19 . The apparatus of  claim 17  wherein the compressed gas is contained within a replaceable compressed gas cartridge. 
     
     
         20 . The apparatus of  claim 17  in which the pressure activated electric switch includes an electronic push button device.
