A hyperbaric oxygen chamber negative pressure system

Abstract

The invention discloses a negative pressure system of a high pressure oxygen cabin. The negative pressure system of the high pressure oxygen cabin comprises the high pressure oxygen cabin; a digital display electrically-connected pressure gauge is connected outside the high pressure oxygen cabin; the digital display electrically-connected pressure gauge is connected with a control center; a continuous negative pressure system is connected outside the high pressure oxygen cabin; the continuous negative pressure system is connected with the control center; after the negative pressure system is used, when the pressure in the high pressure oxygen cabin is less than 0.13MPa, equipment in the cabin with an absorption terminal is communicated with the negative pressure system of a medical center; the negative pressure value is the sum of the pressure in the cabin and the negative pressure of the negative pressure system of the medical center, so that the equipment in the cabin with the negative pressure absorption terminal is ensured to have enough negative pressure absorption capability in the stage, sputum is effectively absorbed; and when the pressure in the cabin is more than or equal to 0.13MPa, the negative pressure absorption system in the high pressure oxygen cabin is separated from the negative pressure system of the medical center through a solenoid valve, and the negative pressure of the negative pressure absorption terminal in the high pressure oxygen cabin comes from pressure difference of the interior and the exterior of the cabin.

Description

technical field [0001] The invention relates to the field of medical equipment and facilities, and more specifically relates to the technical field of a medical hyperbaric oxygen chamber negative pressure control system. technical background [0002] At present, the source of negative pressure in domestic multi-person air pressurized oxygen chambers is mainly the pressure difference between the inside and outside of the chamber when the oxygen chamber is pressurized. At 0.13MPa, the negative pressure of the multi-person air pressurized oxygen chamber is less than 30KPa, and the sputum suction operation cannot be effectively implemented, which will cause the patient to face the risk of suffocation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hyperbaric oxygen chamber negative pressure system capable of ensuring that the pressure in the chamber is not lower than 0.13MPa during the initial stage of pressurizat...
