Oxygen uptake instrument

Abstract

The invention discloses an oxygen uptake instrument which comprises a sealing mask assembly, an air pipeline, an oxygen branch pipeline, an air flowmeter and a control device, wherein the sealing mask assembly is provided with an expiration hole and an admission hole; an expiration one-way valve which is communicated with the atmosphere is arranged at the expiration hole of the sealing mask assembly; an admission one-way valve is arranged at the admission hole; the air pipeline is provided with a first end and a second end; the first end of the air pipeline is communicated with the expiration hole of the sealing mask assembly in an airtight manner; an air inlet one-way valve which is communicated with the atmosphere is arranged at the second end of the air pipeline; the oxygen branch pipeline is communicated with the air pipeline in an airtight manner; the oxygen branch pipeline can be connected with an oxygen supply source through a solenoid valve; the air flowmeter is arranged in the air pipeline; the control device is connected with the air flowmeter and the solenoid valve and is used for controlling the oxygen flow inside the oxygen branch pipeline according to individual air expiration amount detected by the air flowmeter, of an oxygen taker. By adopting the oxygen uptake instrument disclosed by the invention, not only is the taken oxygen concentration automatically and accurately controlled and monitored, but also a great deal of oxygen is saved, and the comfort in oxygen taking is improved.

Description

Technical field [0001] The invention relates to an oxygen inhaler, in particular to an oxygen inhaler that automatically controls oxygen concentration. Background technique [0002] At present, the traditional oxygen inhalation method under autonomous breathing at home and abroad is to inhale oxygen through a face mask or an open nasal cannula, which can only control the oxygen flow rate and cannot accurately control the inhaled oxygen concentration. The effects and side effects of oxygen therapy mainly depend on the oxygen concentration. When traditional masks or nasal catheters are used to inhale oxygen, a large amount of oxygen is wasted into the air. The actual increase in the concentration of inhaled oxygen is limited. Some people who need to inhale a higher concentration of oxygen cannot achieve the desired effect. In addition, traditional oxygen inhalation methods waste a lot of oxygen. It will cause frequent replacement of oxygen bags or tanks when inhaling oxygen at hom...
