Technical Field
The invention relates to a hyperbaric oxygen treatment device, in particular to a carbon dioxide and oxygen mixed hyperbaric oxygen treatment device.
Background
The lack of blood supply to human tissues can lead to the lack of nutrients and oxygen, thereby causing chronic ischemic-hypoxic diseases such as cell metabolism disorder and the like. The diseases are treated clinically by adopting measures of promoting blood circulation to remove blood stasis, expanding blood vessels, reducing blood viscosity and the like, the treatment process really exerts a certain degree of curative effect, and if a correct hyperbaric oxygen treatment method is combined, the clinical curative effect is more prominent. At present, hyperbaric oxygen therapy is sometimes adopted clinically for chronic ischemia and hypoxia diseases, but pure oxygen is taken as a basis, and the blood flow of a human body is reduced by using pure oxygen. Practice can also prove that the curative effect of treating chronic ischemia and hypoxia diseases by pure oxygen is difficult to be exerted or the clinical treatment aim is difficult to be achieved. Because, even if enough oxygen is available to the cells of human tissue, if the supply of nutrients in the blood is affected or deficient, cellular metabolism may not proceed properly and may even produce too many oxygen radicals to damage the tissue cells.
Most of the existing oxygen pressurized oxygen chambers are pressurized by pure oxygen to the treatment pressure specified by high-pressure oxygen treatment, and are ventilated by oxygen to ensure that the oxygen concentration in the chamber is improved as much as possible. Although this method can achieve the high oxygen partial pressure conditions required for oxygen pressurized oxygen chamber therapy, it is difficult to achieve the desired therapeutic effect.
In the dry oxygen environment in the cabin, static accumulation can be generated due to difficulty in dredging, and electrostatic sparks can be generated due to excessive static accumulation, so that the oxygen pressurizing cabin is easy to cause fire accidents, and therefore, the safety potential hazard is high.

The cabin body pressure increasing valve 2 and the cabin body pressure reducing valve 9 are respectively connected with the controller 6, and the controller 6 controls the working state and the opening degree of the cabin body pressure increasing valve 2 and the cabin body pressure reducing valve 9. The pneumatic film regulating valve is provided with an electric converter, and the electric converter is matched with the cabin body pressurizing valve 2 and the cabin body pressure reducing valve 9 for use, so that the pneumatic film regulating valve can accurately control the pressurization and the pressure reduction of the cabin body.
The carbon dioxide mixed oxygen treatment device and the use method are characterized by comprising the following steps:
before use, the cabin body is connected with an oxygen source 1 through a cabin body pressure valve 2, and the oxygen source 1 can be any one of medical molecular sieve oxygen generation equipment, liquid oxygen or bottled oxygen.
a. The human body enters the compression chamber body in a lying position and a single-person mode. The cabin body is sealed through a sealing door.
b. Detecting carbon dioxide concentration in the cabin by using a carbon dioxide concentration sensor and detecting by using a pressure sensor
The pressure in the cabin is converted into a carbon dioxide partial pressure value through a controller; the water content in the oxygen is converted by the controller by utilizing the temperature in the cabin detected by the temperature sensor and the humidity in the cabin detected by the humidity sensor.
c. The carbon dioxide concentration in the cabin body is detected by a carbon dioxide concentration sensor and is transmitted to a controller,
when the concentration of the dioxide in the cabin reaches 1.2-2.2% (preferably 2.0%), opening the pressurizing valve of the cabin body, pressurizing the cabin body by using oxygen of an oxygen source, and closing the pressurizing valve of the cabin body when the internal pressure of the cabin body reaches a set value of treatment pressure (preferably the gauge pressure is 0.1 MPa); on the basis of the ambient temperature detected by the temperature sensor in the cabin, the ambient humidity in the cabin reaches more than 60% at a set temperature (22-26 ℃).
d. When human body stays under the treatment pressure and the carbon dioxide partial pressure value reaches the set value of 15-40mmHg (preferably 23 mmHg), the cabin body pressurization valve and the cabin body decompression valve are opened for ventilation and air exchange by oxygen, the carbon dioxide partial pressure value is always maintained in the specified set value range under the condition that the pressure in the cabin body is kept unchanged, and the humidity in the cabin is maintained in the normal range by oxygen ventilation and air exchange control.
e. When the staying time of the human body in the cabin reaches a treatment set value, a pressure reducing valve of the cabin body is opened to reduce the pressure, the pressure reducing valve is opened in the pressure reducing process, and the ventilation and the air exchange are continuously carried out by oxygen source and oxygen under the control of a computer controller, so that the carbon dioxide partial pressure value and the humidity in the cabin are maintained within a specified range under the state of a specified pressure reducing rate.

The specific process is as follows: when the pressure of the cabin body is kept unchanged in the staying process of a human body in the cabin, the larger the oxygen supply amount of the cabin body or the opening angle of the pressure valve is, the smaller the carbon dioxide partial pressure value and the humidity in the cabin are, and the smaller the oxygen supply amount of the cabin body or the opening angle of the pressure valve is, the larger the carbon dioxide partial pressure value and the humidity in the cabin are; similarly, the larger the exhaust volume or opening angle of the pressure reducing valve of the cabin body is, the more gas is exhausted to the outside of the cabin, and the smaller the partial pressure value and humidity of carbon dioxide in the cabin are. The control of the partial pressure value and the humidity of the carbon dioxide in the cabin is realized by controlling the cabin pressure adding valve and the cabin pressure reducing valve through the computer controller.
Generally, the therapeutic pressure setting value of the cabin is 0.1MPa gauge pressure (absolute pressure = normal pressure + gauge pressure =2 ATA), and the clinical setting can be adjusted according to different disease conditions, and the adjustment range should meet the relevant regulations of the hyperbaric oxygen treatment scheme; the carbon dioxide partial pressure value in the cabin is usually 15-40mmHg, and is also adjusted according to the clinical treatment requirement or disease condition.

The invention can be used for the human body to directly breathe the gas in the environment in the cabin and directly disperse the gas exhaled by the human body in the cabin, wherein the gas exhaled by the human body mainly contains oxygen, moisture and carbon dioxide. Oxygen can improve the blood oxygen tension of the human body, proper carbon dioxide gas can improve the blood circulation of the human body, and water vapor can humidify the oxygen. Part of carbon dioxide in the exhaled air of the human body is used as a gas source of carbon dioxide mixed oxygen; the moisture in the human body breathing gas is used as a water source for humidifying oxygen, and related supporting equipment does not need to be separately arranged for the links.
