Cabin washing device of pure oxygen cabin

Abstract

A cabin-cleaning device of a pure oxygen cabin comprises an oxygen cabin shell; an oxygen inlet device arranged at any ends inside the oxygen cabin shell; an oxygen exhauster arranged at the other end inside the oxygen cabin shell with respect to the oxygen inlet device. The cabin-cleaning device is characterized in that the oxygen inlet device comprises at least two oxygen inlet ports. Comparingwith the prior art, cabin-cleaning device adopts two or more oxygen inlet ports, so as to effectively improve cabin cleaning effect and effectively prevent dead angle in certain spaces inside the cabin generated because of not being sprayed by oxygen due to the straight-line layout of one oxygen inlet port and one oxygen outlet port, thereby remarkably increasing initial oxygen concentration inside the cabin and making the foundation for improving the therapeutic effect of the pure oxygen cabin.

Description

technical field [0001] The invention relates to an oxygen chamber equipment for medical care, in particular to a pure oxygen chamber cleaning device. Background technique [0002] The pure oxygen chamber (also known as oxygen pressurized medical oxygen chamber) with significant curative effect is to place the patient in a closed environment filled with high oxygen concentration and high pressure. The purpose of curing diseases. Therefore, the oxygen concentration of the patient's breathing gas is a key factor in determining the efficacy of the oxygen chamber. Generally, in order to increase the oxygen concentration during treatment, the method of first increasing the initial oxygen concentration in the cabin is usually adopted. Because the oxygen chamber accounts for 79% of the nitrogen in the chamber before it is put into work, in order to increase the oxygen concentration at this time and achieve a high oxygen partial pressure environment, clinically, it is generally ado...

AI Technical Summary

Problems solved by technology

Practice has proved that the gas replacement in the cabin will be affected in the area deviated from the diagonal line, and the gas replacement in the cabin will become impossible in the area away from the diagonal line. This dead angle where oxygen cannot be replaced will eventually affect the cleaning effect

In addition, some oxygen chambers currently use an air inlet and an air outlet, and arrange them in a straight line on the same side in the chamber. At this time, the gas replacement in the chamber is likely to be short-circuited. The tank cleaning effect of the oxygen tank is not good

[0004] To sum up, for the current tank washing device that only uses a single air inlet and a single exhaust port, no matter what arrangement is adopted, there are problems such as long tank washing time, high oxygen consumption, and low initial oxygen concentration. To meet the requirements of the drawbacks, thus affecting the clinical treatment effect, needs further improvement
