Description

A continuous purification and sterilizer under the working state of the ventilator pipeline

technical field

The utility model relates to a purifying and degerming device, in particular to a continuous purifying and degerming device under the working state of the ventilator pipeline, which is an external connection between the medical ventilator and the patient's artificial airway pipeline, or used in the working state of mechanical ventilation. A ventilator accessory that continuously purifies and sterilizes the gas passing through the pipeline.

Background technique

In medical equipment, as a tool to help patients breathe, ventilators play an important role in first aid and medical procedures. Generally, ventilators provide patients with clean and sterile air, but sometimes, they cannot efficiently remove bacteria and harmful substances in the air. Harmful substances such as pathogens are transmitted to patients through the ventilator-pipe, which is easy to cause The patient is sick or infected.

Nowadays, ventilators filter air through filter layers, namely pre-filters, formaldehyde filters, activated carbon filters, HEPA filters and other filters. The filter layer is complex and the cost of filtration is high. The harmful substances in the filter are selective, and the filtering effect is general.

Photocatalyst is one of the most effective means of air purification in the world today. Under the irradiation of light of specific wavelength, photocatalyst will produce a series of energy conversion process similar to the photosynthesis of chlorophyll in plants, transforming light energy into chemical energy and endowing the surface of photocatalyst with great Strong oxidizing ability, can oxidize and decompose various organic compounds and mineralize some inorganic substances, and has antibacterial effect. Under the irradiation of light, the photocatalyst can absorb the light energy below the band gap energy, and excite the surface to generate electrons (e-) and holes (h+). These electrons and holes have strong reducing and oxidizing abilities, and can react with water or contained oxygen to produce hydroxide radicals and super anion ions. The oxidation energy of these holes and hydroxyl radicals is greater than 120kcal/mol, and has a strong oxidation ability, which can cut and decompose almost all chemical bonds that constitute organic molecules. Therefore, various harmful chemicals and malodorous substances can be decomposed or harmlessly treated to achieve the functions of air purification, anti-pollution and deodorization. The application of photocatalysts is limited to air purification, such as air purification through photocatalysts during decoration, air purification with LED photocatalysts, etc. Photocatalyst technology is rarely applied to ventilators.

Utility model content
