Device for managing oxygen concentration and air quality in an air pressurized chamber and method of use thereof

Abstract

The invention relates to the technical field of medical equipment, in particular to a management device for oxygen concentration and air quality in an air pressurization bin. The device comprises the air pressurization bin, a molecular sieve oxygen and nitrogen separation system, an oxygen recycling system, a nitrogen recycling system, an air quality freshening system and an intelligent micro-electronic control system. The air pressurization bin is communicated with an oxygen source, a buffer gas tank and a gas storage tank; the molecular sieve oxygen and nitrogen separation system is communicated with the air pressurization bin; one end of the oxygen recycling system is communicated with the molecular sieve oxygen and nitrogen separation system, and the other end of the oxygen recycling system is communicated with the oxygen source; one end of the nitrogen recycling system is communicated with the molecular sieve oxygen and nitrogen separation system, and the other end of the nitrogen recycling system is communicated with the air pressurization bin through the buffer gas tank; one end of the air quality freshening system is communicated with air, and the other end of the air quality freshening system is communicated with the gas storage tank; the intelligent micro-electronic control system is connected with the air pressurization bin, the molecular sieve oxygen and nitrogen separation system, the oxygen recycling system, the nitrogen recycling system and the air quality freshening system. The invention further provides a using method of the management device. The using method includes the steps S1-S6. The management device can rapidly reduce oxygen concentration in the air pressurization bin and improve air quality in the bin.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for managing oxygen concentration and air quality in an air pressurized cabin and an application method thereof. Background technique [0002] There are two types of hyperbaric oxygen therapy: one uses hyperbaric oxygen therapy in an oxygen pressurized cabin, and only one person can be accommodated in the cabin, and pure oxygen is used for pressurization. The safety risk (easy to catch fire) is relatively large, and it is rarely used in hospitals across the country; the other uses hyperbaric oxygen therapy in an air pressurized cabin, which can accommodate multiple people for treatment at the same time, using compressed air to pressurize, and the patient wears a mask to inhale oxygen , This method of hyperbaric oxygen therapy is commonly used in hospitals across the country. The process of hyperbaric oxygen therapy is divided into three stages: pressurization,...

AI Technical Summary

Problems solved by technology

At present, when the oxygen concentration in the cabin rises, the treatment method is to strengthen the ventilation of the cabin with compressed air. Oxygen concentration drops very little

[0006] 1. At present, there are more and more patients with coma, tracheotomy, and restlessness in hyperbaric oxygen therapy. They can only use the first-level oxygen supply mode, and their corresponding oxygen inhalation masks are not sealed or have no corresponding masks (tracheotomy, tracheotomy, child patients, etc.), or the mask must be removed in the middle (need to suck sputum, cough, etc.), etc., causing too much oxygen to flow into the cabin

[0007] 2. When the patient exhales, there is a positive pressure inside the mask, and the mask is easy to leak, causing the exhaled gas to be discharged into the cabin, and the oxygen concentration in the exhaled gas can also be as high as 50% or more

[0011] Of course, as the oxygen concentration in the cabin increases, the potential safety hazards also increase.

In response to this phenomenon, hyperbaric oxygen in various hospitals currently adopts measures such as increasing ventilation, reducing treatment of patients or critically ill patients, and reducing oxygen flow input, etc., but these cannot achieve a good effect of reducing the oxygen concentration in the cabin, and do not Facilitate the treatment of patients and the clinical application of hyperbaric oxygen

[0012] (2) The air in the air pressurized cabin is turbid, prone to hospital infection
