Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical oxygen generators, in particular to a molecular sieve oxygen making mechanism. Background Art
[0002] Most hospitals now use medical molecular sieve oxygen generators to produce oxygen to meet the requirements of patients. Molecular sieve oxygen production refers to the use of the adsorption characteristics of molecular sieves at room temperature to separate and produce oxygen from the air. Its working principle is to use zeolite molecular sieves and pressure swing adsorption technology (PSA) to separate oxygen and nitrogen in the air, and filter out harmful substances in the air, thereby obtaining high-purity oxygen that meets medical oxygen standards. The current common molecular sieve oxygen production mechanism includes molecular sieves, compressors for conveying air to molecular sieves, oxygen tanks, air valves and other structures. When this type of molecular sieve oxygen production mechanism is in use, the nasal tube for external oxygen delivery is usually connected to the oxygen tube of the oxygen concentrator. When the nasal tube is subjected to external force, or when the oxygen concentrator is subjected to external force, the nasal tube may fall off from the oxygen tube of the oxygen concentrator, affecting the user experience. For this reason, we propose a molecular sieve oxygen production mechanism to solve the above problems. Utility Model Content
