This utility model discloses a micro hyperbaric oxygen chamber and its highly integrated micro hyperbaric oxygen chamber main unit, relating to the field of micro hyperbaric oxygen chamber technology. The highly integrated micro hyperbaric oxygen chamber main unit includes: a shell; an oxygen generation and pressurization device, which includes an air compressor for pressurizing air to a set pressure and a molecular sieve for oxygen generation, the air compressor being connected to the chamber body via an air supply pipe; a pressure regulating and filtration device, which is used to regulate the concentration and pressure of oxygen, the molecular sieve being connected to the pressure regulating and filtration device, the pressure regulating and filtration device being connected to the chamber body via an oxygen supply pipe; a water treatment device, which includes a collection tank and a water processor located in the collection tank, the shell having a guide pipe for guiding the condensate generated by the chamber's air conditioning system and the pressure regulating and filtration device into the collection tank, the water processor being used to vaporize the condensate in the collection tank; and a control device. This device can effectively treat the chamber's air conditioning water and the main unit's condensate, integrating oxygen generation, pressurization, and condensate treatment functions into one unit.

The present application relates to the technical field of interventional medical instruments, in particular to a pressure-controllable super-high-oxygen myocardial perfusion device and a pressure control method. The device comprises a normal-pressure oxygenation cavity, a heat exchange cavity and a high-pressure oxygenation cavity connected in sequence, and a main circulation loop and a static high-pressure oxygenation bypass; the inlet and outlet of the high-pressure oxygenation cavity are both provided with a blockage type peristaltic pump with pumping and sealing functions, the peristaltic pump is internally provided with an oxygenation membrane, and is configured with a pressurizing mechanism for simultaneously pressurizing liquid sides and oxygen sides on both sides of the oxygenation membrane, and a heat exchange mechanism for cooling the perfusion liquid to about 14 DEG C. The present application can prepare super-high-oxygen myocardial protective liquid with oxygen partial pressure higher than 700 mmHg through static, low-temperature and high-pressure oxygenation while maintaining extracorporeal circulation continuous perfusion, significantly improve the myocardial protection effect, and has the advantages of compact structure, precise control and safe operation.
