초록 ▼

A patient ventilator system provides a controllable flow and volume of a mixed inhalation gas to a patient, and receives exhaled gas from the patient. The ventilator system includes gas flow controllers that mix air and oxygen, and provide the mixture to the patient with a controllable inhalation cycle. The ventilator system monitors the resulting patient pressures and volume of gas exhaled by the patient, as necessary. Compressed air is provided to the gas controller in the event of an absence of an external gas supply by a compressor. A controller permits the user of the ventilator system to control ventilation mode, gas pressure, composition, and flow rate of the mixed gas with a single control knob.

대표청구항 ▼

CM,1. A ventilator system for use in assisting a patient to breathe, comprising: gas control means for mixing and regulating the gas that is to flow to a patient and receiving the gas that flows from the patient, the gas control means including flow control means for mixing together controllable amounts of two gases to form a mixed gas that flows to the patient, the flow control means including a separate, independently controllable custom-calibrated rotary flow control valve for each of the two gases; and controller means for independently controlling the two rotary flow control valves, wherein the controller means includes a calibration table for each of the rotary flow control valves, the calibration table including a correlation of gas flow rate as a function of rotary flow control valve position relative to a rotary flow control valve zero flow position, and means for automatically and periodically determining the rotary flow control valve zero flow position corresponding to a zero flow of each of the rotary flow control valves.
