Portable medical gas delivery system
View Patent ↗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 the 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.
1. An apparatus for dispensing medical grade gas, said apparatus comprising:
a portable compressed gas unit including:
a housing including a cylinder cartridge puncture valve,
at least one container of a compressed medical grade gas secured to said cylinder cartridge puncture valve, said container having a capacity from 16 grams to 45 grams,
a solenoid communicably connected to said container, said solenoid including an inlet and an outlet,
a pressure adjustable gas regulator separate and distinct from said solenoid and communicably interconnected between said container and said inlet of the said solenoid for selectively adjusting the pressure of the gas provided from said container to said solenoid, said gas regulator including a regulator adjustment knob to provide a selected level of pressure,
a pressure gauge connected between said gas regulator and said solenoid,
a source of electrical power connected to the solenoid, and
a pressure activated electric switch connected to the power source and being engaged to selectively open said solenoid; and
a conduit communicably attached to said outlet of said solenoid for transmitting said gas to a destination for storage or use in a medical application when said solenoid is opened by operation of said pressure activated switch.
2. The apparatus of claim 1 wherein said compressed gas includes at least one of carbon dioxide, atmospheric air, helium and oxygen.
3. The apparatus of claim 1 wherein said compressed gas is contained within a replaceable compressed gas cartridge.
4. The apparatus of claim 1 wherein said power source includes a single battery that is mounted directly on said solenoid by a battery holder.
5. The apparatus of claim 1 in which said pressure activated switch includes an electronic push button device.
6. The apparatus of claim 1 in which said switch opens said solenoid in response to being engaged by voluntary fingertip pressure.
7. An apparatus for dispensing quantities of medical grade CO 2 in any reservoir of a physician's choice, said apparatus comprising;
a portable compressed CO 2 unit including,
housing including a cylinder cartridge puncture valve,
a cylinder containing compressed medical grade CO 2 , said container having a capacity from 16 grams to 45 grams,
a solenoid communicably connected to said cylinder secured to said cylinder cartridge puncture valve, said solenoid including an inlet and an outlet,
a pressure adjustable CO 2 regulator separate and distinct from said solenoid and communicably interconnected between said cylinder and said inlet of said solenoid for selectively adjusting the pressure of CO 2 provided from said cylinder to said solenoid, said gas regulator including a regulator adjustment knob to provide a selected level of pressure,
a pressure gauge connected between said gas regulator and said solenoid,
a source of electrical power connected to said solenoid and
a pressure activated electric switch connected to said source of electrical power and being engaged to open said solenoid; and
a conduit attached to said outlet of said solenoid for transmitting said CO 2 to a destination for storage or use in a medical application when said solenoid is opened by operation of said pressure activated switch.
8. The apparatus of claim 7 wherein said power source includes a single battery that is mounted directly on said solenoid by a battery holder.
9. The apparatus of claim 7 in which said pressure activated switch includes an electronic push button device.
10. The apparatus of claim 7 in which said switch opens said solenoid in response to being engaged by voluntary fingertip pressure.
