Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a track type connecting structure of high pressure oxygen cabin automatic closing door. BACKGROUND

[0002] The high pressure oxygen cabin makes the oxygen partial pressure in the human body alveolus improve obviously by increasing the oxygen pressure in the environment.

[0003] For example, in the treatment of carbon monoxide poisoning, the affinity of carbon monoxide to hemoglobin is 200-300 times higher than that of oxygen, which will cause hemoglobin to lose the ability to carry oxygen. High pressure oxygen treatment can quickly replace the carbon monoxide combined with hemoglobin, while increasing the blood oxygen content, reducing the damage of poisoning to the brain, heart and other important organs. The door frame is a basic frame for installing the cabin door and is usually tightly connected with the cabin body to provide an installation position and support for the cabin door.

[0004] The existing high pressure oxygen cabin door is divided into two types: manual closing and automatic closing. The manual closing inside opening door is rotated to close the high pressure oxygen cabin door after the user enters the high pressure oxygen cabin, and the door needs to be manually pressed against the door after the cabin is pressurized. The automatic closing sliding door usually uses two groups of motors to realize the translation and front sealing operation of the door, and the operation is two steps, which is relatively complicated, has low reliability, and has high cost of fault replacement and repair.
