Description
Technical Field
The invention relates to the field of medical care equipment, in particular to a single high-pressure oxygen treatment device.
Background
Hyperbaric oxygen therapy refers to a treatment method in which pure oxygen or high concentrations of oxygen are breathed under hyperbaric conditions to treat hypoxic conditions and related conditions. The hyperbaric oxygen therapy has good curative effect on all diseases such as hypoxia and ischemia, or a series of diseases caused by hypoxia and ischemia, and certain infectious diseases and autoimmune diseases.
Hyperbaric treatments need to be performed at pressures above ambient and therefore require a device capable of providing hyperbaric pressures, referred to as a hyperbaric chamber. The existing hyperbaric oxygen chambers are mainly divided into two types,
one is an air compression chamber, namely, air is injected into a chamber body to increase the pressure in the chamber body, and a patient breathes oxygen through an oxygen mask. Because the pressure is increased by air, the hyperbaric oxygen chamber is safe, has larger volume, can contain a plurality of patients for treatment at one time, and has loose environment of the whole chamber body.
However, such hyperbaric chambers are inconvenient to transport and expensive because of their large volume. Moreover, such hyperbaric oxygen chambers are prone to fire because of the high pressure, and because multiple persons are in the same space, the air pressure in the space cannot be adjusted for each person, and cross-contamination between patients is likely to occur.
The other type is a pure oxygen cabin, wherein pure oxygen is directly injected into a cabin body to increase air pressure, and after the pressure is stable, a patient directly breathes oxygen in a breathing cabin. The pure oxygen chamber has small volume, low price and easy transportation. However, since the pressurized medium is oxygen, fire is likely to occur under high pressure and at an extremely high oxygen concentration, and thus, domestic and foreign oxygen chamber combustion accidents frequently occur in such chamber types. Since such oxygen chambers can accommodate only one person, claustrophobia may occur in some patients.
In addition, the large hyperbaric oxygen chamber has larger volume and larger entrance and exit, so that the patient can easily enter and exit the hyperbaric oxygen chamber. However, the pure oxygen chamber has a small volume and a small entrance and exit, and can only be entered by people lying down, which is inconvenient for people to enter.
As the hyperbaric oxygen chamber has large volume, wide occupied area, complex structure and difficult maintenance, the hyperbaric oxygen chamber can not be equipped in part of the third hospitals in large cities, and patients can not be treated by hyperbaric oxygen. Therefore, a small, low-cost hyperbaric oxygen chamber is necessary.
