Medicinal oxygen supply device

Abstract

The invention discloses a medical oxygen supply device. The medical oxygen supply device comprises a main oxygen source oxygen-supply loop, a standby oxygen source oxygen-supply loop and a controller, wherein the main oxygen source oxygen-supply loop comprises an oxygen generator, a first solenoid valve and a one-way valve; the oxygen generator, the first solenoid valve and the one-way valve are sequentially connected through gas pipelines; a gas concentration sensor is arranged on a gas pipeline between the first solenoid valve and the one-way valve; an output end of the one-way valve is connected with oxygen consumption equipment; the standby oxygen supply loop comprises bottled oxygen, decompression equipment and a second solenoid valve; the bottled oxygen, the decompression equipment and the second solenoid valve are sequentially connected through gas pipelines; the output end of the second solenoid valve is connected with the oxygen consumption equipment; and the controller is separately in signal connection with the first solenoid valve, the gas concentration sensor and the second solenoid valve. According to the medical oxygen supply device disclosed by the invention, the controller acquires data of the gas concentration sensor on an oxygen gas loop and the pressure sensor, so that oxygen source switching is realized for the solenoid valves and the one-way valves on the main oxygen source loop and the standby oxygen source loop.

Description

technical field [0001] The invention relates to the field of medical oxygen supply, in particular to a medical oxygen supply device. Background technique [0002] At present, the oxygen supply devices in hospitals all use the combination of the main oxygen source and the backup oxygen source to supply oxygen. Intermittent oxygen supply. Existing oxygen source switching is mainly done manually, and is supervised by a special person. It is necessary to grasp the timing of oxygen source switching, require certain professional knowledge and experience, and the labor cost is relatively high. [0003] In view of the above problems, the Chinese invention with the application number 201220647491.5 discloses a medical oxygen supply device with the function of automatically switching oxygen sources, mainly installing a pressure regulating device on the supply circuit of the main oxygen source and the backup oxygen source, and setting a pressure valve value, when the main oxygen sour...
