Description

A device for recovering and discharging anesthesia ether waste gas

technical field

The invention relates to the technical field of medical devices, in particular to a device for recovering and discharging anesthesia ether waste gas.

Background technique

Anesthetic drug delivery systems in surgical settings (medical, dental, and veterinary) generate large amounts of waste anesthetic gas. Exhaled air from patients is currently collected by dedicated or shared vacuum systems. Healthcare facilities typically employ one or more central vacuum pumps to collect exhaust air from individual anesthesia locations. These vacuum pumps are generally oversized, so they are designed to collect exhaled anesthetic gases over a wide range of flow rates. Because these pumps run continuously, the waste anesthetic gas aspiration system also draws large amounts of ambient room air from the anesthesia site, diluting the waste anesthetic gas significantly. In central vacuum pumps, the airflow is often mixed with other room air to further dilute it before being exhausted from the unit. This diluted spent anesthetic gas/gas mixture is typically pumped outside of the surgical equipment to be vented into the open atmosphere.

With the continuous development of medicine, various new anesthetics have come out one after another and the inhalation-type general anesthesia operation has gradually increased. The problem of anesthesia exhaust gas in the operating room has attracted more and more attention. Personnel have certain injuries, especially anesthesia staff and operating room staff, whose incidence rates of abortion, bone resistance and malignant tumors are much higher than those of non-operating room staff.

Further, the first filter layer is provided with ozone gas; the second filter layer is provided with activated carbon; the pores adopt a super-hydrophobic film with a pore size of 50 nanometers; ozone destroys microorganisms with the oxidation of oxygen atoms Membrane structure to achieve bactericidal effect. The inactivation reaction of the ozone gas in the first filter layer to the bacteria is always very fast. The difference from other fungicides is that the ozone can react with the double bonds of the lipids of the bacterial cell wall, penetrate into the inside of the bacteria, and act on the protein. and lipopolysaccharide, altering the permeability of cells, leading to bacterial death. Ozone also acts on nuclear substances in cells, such as purines and pyrimidines in nucleic acids to damage DNA. Ozone first acts on the cell membrane, causing damage to the membrane components, resulting in metabolic disorders. Ozone continues to permeate through the membrane, destroying the lipoproteins and lipopolysaccharides in the membrane, changing the permeability of cells, leading to cell lysis and death, which is harmful to anesthesia. After the exhaust gas is sterilized first, the activated carbon in the second filter layer deodorizes the anesthesia exhaust gas that has passed through the first filter layer through the physical characteristics of activated carbon; the pores use a super-hydrophobic film with a pore size of 50 nanometers to ensure that the anesthesia molecules can Enter the heating room through the air holes, and the liquid water in the heating room cannot flow out through the air holes.

This product can be arbitrarily mixed with ethanol, chloroform, benzene, petroleum ether, fatty oil or volatile oil, and can be dissolved in water. The boiling point is 33.5-35.5°C, and the water liquid in the heated room can effectively absorb the anesthetic ether in the anesthetic waste gas.

Further, the composition of the collection box is: polypropylene, polyethylene and ionomer resin, the mass ratio of which is 1:1:1; the above-mentioned materials do not contain Lewis acid that can promote the decomposition of inhaled and released anesthetic agents, and can Better resistance to vapors entering and leaving the container, while the container's resistance to breakage is enhanced compared to glass containers.

Further, both the first filter layer and the second filter layer adopt a V-shaped structure; because the general anesthesia waste gas purification device of the present invention is provided with a multi-layer filter screen, it can fully filter the general anesthesia waste gas, so that the filter The harmful substance contained in the air is very low; at the same time, the total anesthesia exhaust gas entering the present invention can fully contact with the purification material, thereby further reducing the harmful substance contained therein.
