Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical devices, and specifically relates to a disposable anesthetic mixed gas adsorption and bacteria inhibition device. BACKGROUND

[0002] Anesthetic gas adsorption and bacteria inhibition technology is mainly used in the medical field, especially in operating rooms, ICUs, recovery rooms, and anesthesiology research laboratories. It is used to treat anesthetic waste gas exhaled by patients. These waste gases usually contain volatile anesthetics and other harmful gases, which not only pollute the medical staff and the surrounding environment, but also may cause health problems such as chronic fluoride poisoning, genetic effects (mutagenic, teratogenic, and carcinogenic). In order to solve this problem, anesthetic gas adsorption and bacteria inhibition devices have emerged. These devices usually use activated carbon or molecular sieve adsorbent to remove harmful substances in waste gas through adsorption. Some advanced devices are also equipped with a filtration system to further remove particulate matter and microorganisms in waste gas, improving the purification effect.

[0003] According to the Chinese patent with the patent number CN220193764U, an absorption and filtration type anesthetic adsorber is disclosed, which includes a tank body, a base, a filter cotton pad I, a filter cotton pad II, a ventilation support sheet I, a ventilation support sheet II, a carbon dioxide absorbent, and an air outlet pipe. The anesthetic gas is evenly dispersed in the interlayer region between the ventilation support sheet I and the top surface of the tank body, allowing the anesthetic gas to penetrate through the entire filter cotton pad I. After the impurities in the anesthetic gas are filtered by the filter cotton pad I, the gas enters the carbon dioxide absorbent area inside the tank body. The gas that has absorbed the carbon dioxide flows downward. The filter cotton pad II filters the calcium lime dust in the gas, and the pure anesthetic gas enters the area below the base through the ventilation support sheet II. The anesthetic gas is then discharged through the air outlet pipe and the air outlet interface on the upper part of the air outlet pipe.

[0004] However, in the existing anesthetic mixed gas adsorption and bacteria inhibition device, when the user adjusts the device to the awakening state, the anesthetic mixed gas flows into the adsorption cavity containing activated carbon. Traditional adsorption cavities are straight cylinders, and due to the small size of the disposable anesthetic mixed gas adsorption and bacteria inhibition device, a small amount of anesthetic mixed gas may not come into contact with the activated carbon, resulting in incomplete adsorption of the anesthetic mixed gas.

[0012] As a preferred technical scheme of the utility model, the docking pipeline is opened with limiting track, the insertion pipeline is fixed with limiting ring on the outside, and the limiting ring is rotatably connected in the limiting track.
