A closable oxygen exhaust interface device for hyperbaric chambers

Abstract

The utility model provides a kind of closable oxygen exhaust interface device for hyperbaric oxygen chamber, it is related to high pressure oxygen cabin equipment technical field, including front end and main part, main part is movably sleeved in front end, several movable diaphragms are provided in front end, the one end of main part is provided with several fixed diaphragms, movable diaphragm is matched with fixed diaphragm, and compression member is installed on main part, the other end of compression member is installed in front end, and compression member is used to make movable diaphragm and fixed diaphragm adhere to each other.The utility model is through the cooperation of movable diaphragm and fixed diaphragm, and compression member makes both adhere to each other, when rotating, the size of oxygen exhaust of front end can be adjusted, gas source gas consumption is saved, consumption is reduced, efficient use of resources is realized, cabin air is not discharged when there is no patient oxygen inhalation, the interference to the oxygen exhaust speed and oxygen exhaust volume of other patients is avoided, the normal breathing of other patients is guaranteed, the respiratory comfort is improved, the probability of waste oxygen leakage is greatly reduced, which helps to stabilize the oxygen concentration in the cabin.
