Description

Oxygen-supply type oxygen-inhaling pipeline one-way valve according to demand

Technical Field

The utility model belongs to the technical field of oxygen tube technique and specifically relates to an oxygen uptake pipeline check valve of oxygen supply type as required.

Background

Oxygen is a gas necessary for human life, is a necessary substance for producing energy required by human functional activities, and is an indispensable vital element of human body. Oxygen "code-plus" inhalation (oxygen therapy) is one of the advantages of humans in treating diseases and even combating epidemics. At present, common oxygen inhalation devices comprise nasal catheter oxygen inhalation, mask oxygen inhalation, nasal high-flow oxygen therapy, positive pressure oxygen supply of a breathing machine, high-pressure oxygen therapy and the like. Except that the high-pressure oxygen therapy is limited to be applied in a high-pressure oxygen chamber of large special equipment, and the common problem of adopting other common oxygen inhalation devices is that no matter a patient inhales or exhales, oxygen is continuously supplied, but only the oxygen is utilized when the human body inhales, and all the oxygen at other times enters the air to cause waste. Taking transnasal high-flow oxygen therapy as an example, the principle is that high-flow oxygen is supplied at 30-70 liters/minute to ensure the most sufficient oxygen inhalation of a patient, the flow of 50 liters/minute is generally adopted, and the actual oxygen consumption per minute is about 50 liters; normal human breathing tidal volumes are about 500 ml and the actual inhaled gas volume is about 7.5 liters per minute, so a significant amount of oxygen is effectively wasted indefinitely. If the mask is matched with the oxygen inhalation device of the oxygen supply type oxygen inhalation pipeline one-way valve according to needs to inhale oxygen, the patient can supply the oxygen according to needs, the actual oxygen consumption of the patient per minute is about 7.5-9 liters per minute, and compared with the prior art, the oxygen can be saved by about 41 liters per minute. In addition, if nasal high-flow oxygen therapy or mask oxygen inhalation is adopted, if a plurality of people inhale oxygen at high flow in one treatment space at the same time, the potential safety hazard of fire caused by the fact that the air oxygen concentration in a small environment greatly exceeds the standard can be caused, and the shortage of oxygen resources due to short-time extrusion can be caused, so that the development and implementation of group treatment are influenced. The method has prominent influence on the treatment of serious disasters and serious infection epidemic situations in plateau anoxic areas.
