Description
Technical Field
The invention relates to the technical field of hyperbaric oxygen chambers, in particular to a high-pressure oxygen chamber based CO 2 And O 2 High-pressure oxygen bin system and device for mixed gas.
Background
Currently, hyperbaric oxygen chambers are classified into pure oxygen chambers and air pressure chambers. The air pressurizing cabin which can be used by multiple people is commonly used in all hospitals at present. The air pressurizing oxygen cabin mainly comprises an air pressurizing and pressurizing system, an oxygen supplying and exhausting system, an air conditioning system, an electrical system, a control system, a fire fighting system and the like. The pressurizing medium is air, and the highest working pressure of air pressurization is not more than 0.3MPa. The air pressurization is divided into a single oxygen cabin and a multi-oxygen cabin according to the number of people treated in the cabin. Whether the device itself is acceptable is one cause of explosion. Pure oxygen chambers, a method of treating certain diseases by placing a patient in a higher than one atmosphere through a hyperbaric oxygen chamber to absorb pure oxygen is called hyperbaric oxygen therapy. The oxygen absorption concentration is 85% -99%, the oxygen content is tens times than that of oxygen absorption under normal pressure, the oxygen tension can be effectively improved, the oxygen content can be increased, and the oxygen absorption device has special curative effect on treating certain acute and chronic anoxic diseases.
Currently, the oxygen supply mode is commonly used:
1. full cabin oxygen supply method: i.e. a method for use in a single person pure oxygen cabin. The pure oxygen is utilized for washing the cabin and then is pressurized, so that a patient does not need to wear an oxygen supply mask in the cabin to directly breathe the high-concentration oxygen in the oxygen cabin.
2. Mask oxygen delivery method: namely a method for pressurizing the oxygen inhalation device in the cabin by using air. After reaching the treatment pressure, the patient wears the oxygen supply device to breathe pure oxygen. There are two methods currently available:
(1) Air bag type mask oxygen supply method (first-stage oxygen supply method): the oxygen supply switch is connected with a rubber air bag, and then is connected with an oxygen supply device to directly supply oxygen; the patient is more labor-saving when inhaling oxygen.
(2) Oxygen supply method (secondary oxygen supply method) of automatic air supply regulator: the cabin is internally provided with a secondary respiratory regulator which is connected with an oxygen supply mask, and a patient can inhale primary oxygen without inhaling or supplying oxygen.
However, the whole-bin oxygen supply method can generate an oxygen poisoning phenomenon due to the adoption of pure oxygen; and the mask type oxygen supply mode is adopted to limit the movement of the patient.
