Gas cylinder type pressure-stabilizing dual-mode oxygen supply device

Abstract

The invention discloses a gas cylinder type pressure-stabilizing dual-mode oxygen supply device. The gas cylinder type pressure-stabilizing dual-mode oxygen supply device comprises a gas cylinder, a nasal oxygen tube and an integrated valve mounted on the gas cylinder, wherein a nasal suction joint on the nasal oxygen tube is inserted into a nasal cavity of a user; a gas outlet outer joint and a gas suction outer joint of the integrated valve are connected with a gas inlet of the nasal oxygen tube; the integrated valve comprises a valve body, a valve cover, a filling module, a flow regulatingmodule and a pulse oxygen supply module, wherein the filling module, the flow regulating module and the pulse oxygen supply module are mounted on the valve body and the valve cover; oxygen in the gascylinder passes through the filling module and the flow regulating module and then is output by the pulse oxygen supply module; the pulse oxygen supply module comprises a gas inlet unit, a gas outletunit and a gas suction unit; and the gas inlet unit comprises a sixth gas channel and a seventh gas channel which are used for feeding gas through the same gas inlet source. According to the gas cylinder type pressure-stabilizing dual-mode oxygen supply device, all mechanical parts are adopted to realize continuous and pulse dual-mode oxygen supply, and a pressure stabilizing module and the filling module are integrated inside, so that the device structure and gas guide tube connection are simplified, and therefore, use of the user is convenient.

Description

Technical field [0001] The invention belongs to the technical field of equipment manufacturing, and relates to an oxygen supply device, in particular to a gas cylinder type stabilized dual-mode oxygen supply device. Background technique [0002] In the production of oxygen supply equipment for plateau oxygen supply, underwater oxygen supply and hospitals for people with breathing difficulties, oxygen cylinders are often used to supply oxygen to users through gas control valves. During use, high-pressure oxygen needs to be filled into the cylinders, and then Leave the gas cylinder to supply oxygen to the user. Existing gas cylinders have a complicated oxygen supply structure, including independent decompression, flow adjustment and output modules. There are many conduits and leads. The gas supply method adopted is to supply air at a fixed flow rate without interruption. During the exhalation and exhalation process, the output oxygen flow rate of the oxygen supply device is consta...

AI Technical Summary

Problems solved by technology

In use, the breathing valve has poor sensitivity to the air outlet of the human body. The user will only supply oxygen in pulses when he is in a state of exercise or inhaling hard. When the human body is in a static state, sleeping state or the valve body is in a horizontal position, it often occurs that there is no air. Or the failure of pulse outlet; in addition, the pulse valve lacks decompression, pressure stabilization and self-sealing filling functions, which limits its popularization and application in many occasions
