Medical oxygen production equipment

Abstract

The invention discloses medical oxygen production equipment which comprises a primary oxygen production box, a cooling dehumidification box, a secondary oxygen production box and an oxygen storage box, the oxygen storage box is communicated with a first oxygen outlet pipeline through a mixing pipeline, an adjusting valve is fixedly arranged in the end, close to the first oxygen outlet pipeline, ofthe mixing pipeline, a cooling elastic plate is fixedly connected to the interior of the cooling dehumidification box, a porous elastic film is movably arranged in the through hole, a pull rope is fixedly connected to the end, extending out of the open groove, of the extension rod, and the end, away from the extension rod, of the pull rope is fixedly connected to the porous elastic film. In use,the oxygen-rich membrane and the molecular sieve are cooperatively used so that the working strength of the molecular sieve is reduced, meanwhile, the cleanliness of the molecular sieve is guaranteed,oxygen with different concentrations is obtained through the mixing pipeline and the adjusting valve, the tensile deformation degree of the cooling elastic plate and the porous elastic film is increased through the oxygen inlet pipe, the screw rod, the toothed plate, the pull rope and other structures, and the cooling and dehumidifying effects are improved.

Description

technical field [0001] The invention relates to the technical field of medical oxygen-generating equipment, in particular to a medical oxygen-generating equipment. Background technique [0002] Modern commonly used oxygen production methods mainly include cryogenic method, molecular sieve pressure swing adsorption method, membrane separation method and magnetic separation method. At present, the molecular sieve pressure swing adsorption method and membrane separation method are mainly used on a large scale. The membrane separation method has the advantages of small volume and low power consumption, but the oxygen concentration obtained by the membrane separation method is generally 30%, which can be used for oxygen therapy. Health care, but the first aid required in severe hypoxia can only use medical high-concentration oxygen. The molecular sieve pressure swing adsorption method can produce oxygen with a concentration of more than 90%, which meets the needs of high-concent...

Problems solved by technology

[0004] However, there are still many deficiencies in the prior art, such as: 1. The oxygen concentration obtained by the above-mentioned technology is high-concentration oxygen, which has few applicable fields and single function; During the preparation process, air dust, bacteria and other impurities are not adsorbed by molecular sieves, but enter the oxygen storage tank together with oxygen, which will reduce the quality of oxygen
