Medical oxygen producing equipment and its control method

Abstract

The medical oxygen production equipment includes air compressor, air storage tank, freeze drying machine, oxygen producing machine, oxygen storage tank, solenoid valves, etc. connected successively. The oxygen producing machine includes absorbing tower, multi-way rotary distributing valve, control solenoid valve, oxygen producing valve, exhaust valve, oxygen determining valve, cylinder and oxygen buffer tank. There are separator and water-separating air filter in the air path between the freeze drying machine and the oxygen producing machine. There is also a controller connected electrically to the constituent parts. The medical oxygen producing equipment of the present invention is small, intelligently controlled and high in efficiency and may be used widely in hospital and in field.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to medical oxygen-generating equipment and a control method. Background technique [0002] Medical oxygen generating equipment occupies an indispensable and important position in medical rescue, especially field rescue. Most of the medical oxygen production technology is to treat the atmosphere, and use electrochemical technology or pressure swing adsorption technology to produce oxygen. Among them, the pressure swing adsorption oxygen production technology generally includes several steps: 1. The air enters the storage tank through the air compressor (membrane pump or electromagnetic pump) for storage; 2. The stored air is dried or ice-dried; 3. The dry gas is separated, etc. Pretreatment (including dust removal, water separation, and secondary dehumidification); 4. The pretreatment gas is treated with several stages of molecular sieves; 5. Oxygen buffer storage; 6. Storage after ...

AI Technical Summary

Problems solved by technology

So, what kind of failure is the multi-way rotary distribution valve? Existing products do not have the ability to detect and sense

Furthermore, the current adsorption tower is not only divided into three-layer structure as a whole, the middle section is connected by a flange, and the lower section is provided with a desiccant. The structure is more messy, the volume is larger and heavier, the towers are not easy to connect with each other, the equipment as a whole is not easy to install and place, and the pipes outside the tower are prone to damage and other failures

[0003] Therefore, with regard to the above-mentioned shortcomings, coupled with the instability of manual control, the existing technology has serious deficiencies in terms of oxygen recovery rate, labor intensity of operators, smooth operation, safety, reliability, etc.
