Hyperbaric oxygen chamber oxygen supply and exhaust system

Abstract

The invention provides a hyperbaric oxygen chamber oxygen supply and exhaust system. According to the system, oxygen is supplied sufficiently, the oxygen supply quality is good, and flow measurement is accurate. The system comprises an oxygen pressure reducer, a buffer tank, multiple humidifying tanks, an oxygen inhalation device and multiple oxygen-water separators. An oxygen supply pipe is connected with an inlet of the oxygen pressure reducer, an outlet of the oxygen pressure reducer is connected with the oxygen inlet end of the buffer tank through an oxygen pipeline, the oxygen outlet end of the buffer tank is connected with one end of a main pipeline, the other end of the main pipeline is connected with one end of each oxygen supply branch pipe simultaneously, the other end of each oxygen supply branch pipe is connected with an inlet of the corresponding humidifying tank, an outlet of each humidifying tank is communicated with the inhalation end of the oxygen inhalation device through the oxygen supply pipe, the expiration end of the oxygen inhalation device is connected with the inlet ends of the oxygen-water separators, and the outlet ends of the oxygen-water separators are connected with an oxygen exhaust pipe through a main oxygen exhaust pipe. An oxygen supply flow meter is arranged on the oxygen supply pipe and an oxygen exhaust flow meter is arranged on the oxygen exhaust pipe.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to an oxygen supply and exhaust system for a hyperbaric oxygen chamber. Background technique [0002] The oxygen supply and exhaust system in the old-fashioned hyperbaric oxygen chamber has no oxygen buffer and humidification device. The oxygen cylinder is directly connected to the oxygen inhalation equipment in the oxygen chamber. Insufficient, affecting the quality of oxygen inhalation of patients. And the oxygen has not been humidified, because the oxygen in the oxygen cylinder has very little water content, only 70mg / m3 at 15°C and 0.1MPa(A), which is only equivalent to 5% relative humidity, breathing this dry gas for a long time, A person may feel discomfort in the throat. The old-fashioned oxygen chamber is not designed with a gas-water separation device. The water vapor generated in the oxygen inhalation hood or mask can easily enter the emergency oxygen discharge flowmeter...

AI Technical Summary

Problems solved by technology

The old-fashioned oxygen chamber is not designed with a gas-water separation device. The water vapor generated in the oxygen inhalation hood or mask is easy to enter the emergency oxygen flow meter, which is easy to make the floating beads stick, moldy and black, and affect the flow measurement.

The above three problems have not been well resolved for many years
