Abstract

A method and apparatus that provides a continuous source of medical grade air. A substantially tubular housing includes a first end, an aperture extending through the housing, and a second end, opposite the first end. A valve extends from the first end of the housing for dispensing medical grade air to a patient.

Claims (55)

1. An apparatus that provides a continuous source of medical grade air comprising:

a substantially tubular and rigid housing including

a first end;

at least one aperture extending through the housing and positioned a predetermined distance from the first end;

a second end, opposite the first end; and

a tubular section between said first end and said second end;

a valve extending from the first end of the housing for dispensing medical grade air to a patient;

a medical grade air compressor that provides medical grade air for output by the valve, the medical grade air compressor being positioned within the housing on a side of the at least one aperture opposite the valve;

an air flow generator positioned between the second end of the housing and the medical grade air compressor, the air flow generator draws air into the housing through the at least one aperture, the air passing over and around the medical grade air compressor to reduce a temperature of the medical grade air compressor and to the medical grade air compressor for generating medical grade air; and

a reservoir fluidly coupled between said medical grade air compressor and said valve for receiving the medical grade air generated by the compressor, storing the medical grade air received from the compressor and providing the medical grade air received from the compressor to the valve for dispensing to the patient,

wherein the at least one aperture includes a plurality of apertures positioned around a circumference of the housing.

2. The apparatus as recited in claim 1 , wherein

the air flow generator is at least one of (a) a fan; (b) a pump; and (c) a vacuum.

3. An apparatus that provides a continuous source of medical grade air comprising:

a substantially tubular and rigid housing including

a first end;

at least one aperture extending through the housing and positioned a predetermined distance from the first end;

a second end, opposite the first end; and

a tubular section between said first end and said second end;

a valve extending from the first end of the housing for dispensing medical grade air to a patient;

a medical grade air compressor that provides medical grade air for output by the valve, the medical grade air compressor being positioned within the housing on a side of the at least one aperture opposite the valve;

an air flow generator positioned between the second end of the housing and the medical grade air compressor, the air flow generator draws air into the housing through the at least one aperture, the air passing over and around the medical grade air compressor to reduce a temperature of the medical grade air compressor and to the medical grade air compressor for generating medical grade air; and

a reservoir fluidly coupled between said medical grade air compressor and said valve for receiving the medical grade air generated by the compressor, storing the medical grade air received from the compressor and providing the medical grade air received from the compressor to the valve for dispensing to the patient,

wherein the medical grade air compressor includes

an air compressor that compresses air to a predetermined pressure;

a first filter connected at an input of the air compressor, the first filter filters ambient particles having a size greater than a threshold size from the air;

a second filter coupled to an output of the air compressor that filters oil and water and removes moisture from the compressed air; and

a cooler assembly coupled to the second filter that receives the compressed air therethrough and dissipates heat from the compressed air.

4. The apparatus as recited in claim 3 , wherein the cooler assembly includes a plurality of copper coils and the air drawn into the housing flows over and around the plurality of copper coils.

5. The apparatus as recited in claim 3 , further comprising

at least one of (a) a medical gas conditioning system; (b) a carbon dioxide filter and (c) a carbon monoxide detector.

6. An apparatus that provides a continuous source of medical grade air comprising:

a substantially tubular and rigid housing including

a first end;

at least one aperture extending through the housing and positioned a predetermined distance from the first end;

a second end, opposite the first end; and

a tubular section between said first end and said second end;

a valve extending from the first end of the housing for dispensing medical grade air to a patient;

a medical grade air compressor that provides medical grade air for output by the valve, the medical grade air compressor being positioned within the housing on a side of the at least one aperture opposite the valve;

an air flow generator positioned between the second end of the housing and the medical grade air compressor, the air flow generator draws air into the housing through the at least one aperture, the air passing over and around the medical grade air compressor to reduce a temperature of the medical grade air compressor and to the medical grade air compressor for generating medical grade air; and

a reservoir fluidly coupled between said medical grade air compressor and said valve for receiving the medical grade air generated by the compressor, storing the medical grade air received from the compressor and providing the medical grade air received from the compressor to the valve for dispensing to the patient,

further comprising

at least one of a thermistor, a temperature sensor and a thermocouple coupled to the medical grade air compressor and the air flow generator, the at least one of thermistor, temperature sensor and thermocouple moveable between a first closed position and a second open position in response in detecting that a temperature of the medical grade air compressor has reached a threshold value.

7. An apparatus that provides a continuous source of medical grade air comprising:

a substantially tubular and rigid housing including

a first end;

at least one aperture extending through the housing and positioned a predetermined distance from the first end;

a second end, opposite the first end; and

a tubular section between said first end and said second end;

a valve extending from the first end of the housing for dispensing medical grade air to a patient;

a medical grade air compressor that provides medical grade air for output by the valve, the medical grade air compressor being positioned within the housing on a side of the at least one aperture opposite the valve;

an air flow generator positioned between the second end of the housing and the medical grade air compressor, the air flow generator draws air into the housing through the at least one aperture, the air passing over and around the medical grade air compressor to reduce a temperature of the medical grade air compressor and to the medical grade air compressor for generating medical grade air; and

a reservoir fluidly coupled between said medical grade air compressor and said valve for receiving the medical grade air generated by the compressor, storing the medical grade air received from the compressor and providing the medical grade air received from the compressor to the valve for dispensing to the patient,

further comprising

one of a temperature sensor and a thermocouple coupled to the medical grade air compressor and the air flow generator, the one of a temperature sensor and a thermocouple moveable between a first closed position and a second open position in response to detecting that a temperature of the medical grade air compressor has reached a threshold value.
