Abstract

The invention discloses a breathing module oxygen mixing device for a portable universal life support system, which comprises an oxygen mixing chamber and a main controller. The oxygen mixing chamber is provided with an oxygen inlet, an air inlet and a mixed gas outlet, and an The proportional valve of the oxygen flow, the outlet of the mixed gas is provided with a turbine, and the controlled ends of the turbine and the proportional valve are respectively connected to the output end of the main controller; the oxygen inlet is close to the mixed gas outlet, and the air inlet is away from the mixed gas outlet; the The interior of the oxygen mixing chamber is provided with a labyrinth structure. The labyrinth structure provided inside the oxygen mixing chamber of the present invention can temporarily store oxygen when adjusting the flow rate extracted by the turbine, so that all the gas extracted by the turbine can be oxygen, and the breathing module outputs gas with 100% oxygen concentration.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a breathing module oxygen mixing device for a portable general life support system. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] The breathing module of the portable universal life support system adapted to the field environment can provide patients with gases of different oxygen concentrations. The oxygen comes from the oxygen source, and the flow...
