Abstract

The invention relates to an intensive care unit center oxygen supply breathing kit which comprises a shell, an oxygen connector and a negative pressure connector, an oxygen inlet pipe and a negative pressure inlet pipe are arranged in the shell, a gas mixing cavity is formed in the shell, a thickening branch pipe and a dilution branch pipe are arranged above the gas mixing cavity, and an output electromagnetic valve is arranged on an oxygen output pipe; a thickening electromagnetic valve and a diluting electromagnetic valve are respectively arranged on the thickening branch pipe and the diluting branch pipe; an electromagnetic valve driving module and an MCU processor are arranged on the inner side of the shell, a control panel is arranged on the outer side of the shell, and an oxygen concentration sensor and a pressure sensor are arranged in the gas mixing cavity. The intensive care unit central oxygen supply breathing kit is arranged in a gas mixing chamber to monitor the concentration and pressure of output oxygen in real time, and the oxygen output concentration is adjusted and set according to feedback signals; thus, a closed-loop feedback control loop is formed, and the oxygen concentration can be automatically controlled within a set threshold value, and a flow manual control function is realized; besides, additional functions such as a power socket and call talkback are provided.

Description

technical field [0001] The invention relates to the technical field of intensive care unit equipment, in particular to a central oxygen supply breathing suit for the intensive care unit. Background technique [0002] With the advancement of medical technology, the design and construction of intensive care units are equipped with oxygen supply and negative pressure supply pipelines to enter the room, while the indoor supporting facilities of intensive care units are mostly relatively simple in structure and installed on the wall. On the interface board directly connected to the above-mentioned inlet pipeline, the interface is usually blocked with a hole plug. Since the oxygen supply equipment and valve body are installed in the central oxygen station, when there is a need for oxygen inhalation, the oxygen concentration and flow must be controlled through the oxygen station. , the operating flexibility and feedback efficiency of output oxygen regulation are not ideal. Conten...
