Description

Technical Field

[0001] This utility model relates to the field of anesthetic gas technology, specifically a novel anesthetic gas recovery and filtration device. Background Technology

[0002] Volatile inhaled anesthetics are halides closely linked to ozone-depleting chlorofluorocarbons (CFCs), making them a major component of ozone layer depletion. Prolonged exposure to anesthetic gases in operating rooms is harmful, especially in the absence of a gas removal system, where exposure to exhaust gases has a greater impact on occupational health. Potential health effects of occupational exposure include fatigue, irritability, headaches, abnormal liver, kidney, and hematopoietic system function, and behavioral changes. Exposure to anesthetic exhaust gases, particularly nitric oxide, can increase the risk of miscarriage, infertility, and birth defects.

[0003] During surgical anesthesia, hospital anesthesiology departments inevitably release anesthetic waste gases to some extent. If these gases are released directly without filtration and purification, they will pollute the air environment of the operating room. If inhaled by medical staff, they can cause dizziness, weakness, and lethargy within a short period of time, affecting their work performance. They will also affect the odor of the surrounding air. Therefore, it is necessary to provide a new type of anesthetic gas recovery and filtration device to solve the above-mentioned technical problems. Utility Model Content

In use, the disinfection tank is filled with sufficient disinfectant, the recovered gas is introduced into the air inlet pipe, enters the ring pipe through the air inlet pipe, then enters each of the vertical pipes, and finally exits through the nozzles, allowing the gas to fully contact the disinfectant solution inside the disinfection tank, so that the gas dissolves in both the disinfectant solution and the water. Finally, the disinfected and filtered gas exits from the exhaust pipe and enters the filter cylinder, where it is adsorbed and filtered by an activated carbon layer, purifying any odors in the gas before finally being discharged, preventing odor emissions from affecting the breathing quality of surrounding people.

[0006] Preferably, the annular tube is fitted inside the disinfection barrel, the disinfection barrel is filled with sufficient disinfectant, and the contact surfaces between the top cover and the disinfection barrel are provided with sealing rings, which can improve the sealing effect between the top cover and the disinfection barrel.

[0008] Preferably, the other end of the air inlet pipe is fixedly connected to a telescopic tube, which can be easily connected to the end where the anesthetic gas is emitted.

[0009] Preferably, a measuring cylinder is fixedly connected to the top of the top cover, a switch is provided on the outside of the measuring cylinder, and disinfectant can be stored inside the measuring cylinder. By closing the switch, the disinfectant inside the measuring cylinder can enter the interior of the disinfection bucket.

[0010] Preferably, a rubber pad is fixedly connected to the bottom of the disinfection tank, and a one-way valve is fixedly connected inside the air inlet pipe. The rubber pad can improve friction and prevent slipping.

[0011] Preferably, two filter cottons are fixedly connected inside the filter cartridge. The two filter cottons are located on both sides of the activated carbon layer. The filter cottons can filter the gas, allowing fine particles to be filtered out, thereby improving the filtration and purification effect.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. When using this utility model, the inside of the disinfection tank is filled with sufficient disinfectant water, the recovered gas is connected to the air inlet pipe, enters the inside of the ring pipe through the air inlet pipe, and then enters the inside of each vertical pipe. Finally, it is sprayed out from the nozzle, so that the gas comes into full contact with the disinfectant inside the disinfection tank, so that the gas dissolves in the disinfectant and water at the same time.

[0014] Second, in this utility model, the gas after final disinfection and filtration is discharged from the exhaust pipe and enters the interior of the filter cartridge. After being adsorbed and filtered by the activated carbon layer, the odor in the gas can be purified and finally discharged, avoiding the odor emission from affecting the breathing quality of the surrounding people.
