Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a multifunctional waste gas adsorber. Background Technology

[0002] In the medical field, especially during surgery and anesthesia, maintaining the cleanliness and safety of respiratory gases is crucial. After anesthesia, it is necessary to absorb and filter the anesthetic gases in the patient's body as soon as possible to accelerate the patient's awakening and recovery process. The carbon dioxide absorption canister plays an important role in the breathing circuit of the anesthesia machine, acting as a "purifier" for the lungs. If the purification function malfunctions and carbon dioxide cannot be filtered properly, it will lead to insufficient effective alveolar ventilation, hindering the smooth expulsion of carbon dioxide metabolized by the body and creating a risk of carbon dioxide retention.

[0003] The above scenarios all involve the absorption and filtration of various waste gases during medical or surgical procedures. Traditional medical filters typically only adsorb and filter a single gas, such as carbon dioxide or anesthetic gases. Patients need to change filters when inhaling carbon dioxide and then anesthetic gases, which not only increases the number of steps but also increases the risk of cross-infection. Therefore, developing a waste gas adsorber that can adsorb and filter both carbon dioxide and anesthetic gases using the same device and has a convenient switching function has significant practical application value. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing medical filters can only filter a single gas, and the replacement operation is relatively complicated and has high safety risks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multifunctional waste gas adsorber includes a tank and a pipe joint disposed above the tank. The tank includes a core cavity and a filter cavity disposed outside the core cavity.

[0007] The pipe joint includes an air inlet and an air outlet; the air inlet and air outlet within the pipe joint are not interconnected.

[0008] The filter cavity includes two pairs of carbon dioxide absorption chambers and anesthetic gas absorption chambers arranged circumferentially. The carbon dioxide absorption chambers and anesthetic gas absorption chambers are arranged adjacent to each other. Carbon dioxide absorption material is provided in the carbon dioxide absorption chambers, and anesthetic gas absorption material is provided in the anesthetic gas absorption chambers.

[0009] The core cavity is equipped with a switching mechanism that can be rotated to connect the pipeline connector and the carbon dioxide absorption chamber or the pipeline connector and the anesthetic gas absorption chamber respectively.

[0010] The switching mechanism includes a rotating drum disposed inside the core cavity, and the top of the rotating drum is fixedly connected to the bottom of the pipeline connector via a rotating plate disposed on the top surface of the tank.

[0011] A base plate is provided at the bottom of the core cavity, and a through hole is provided on the base plate; a base is provided at the bottom of the rotating drum, and a connecting seat is provided at the corresponding position of the through hole on the base; a loading and unloading component for rotating and disassembling switching mechanism is provided at the connecting seat at the bottom of the tank body.

[0012] The top surface of the tank has distinguishing markings in the corresponding areas of the carbon dioxide absorption chamber and the anesthetic gas absorption chamber, and the rotating plate has marking windows for exposing the distinguishing markings when the plate rotates.

[0013] As a further improvement to the above solution, the switching mechanism includes a pair of vents on the rotating plate and respectively connected to the air inlet and air outlet. The rotating cylinder is located below the rotating plate. The rotating cylinder includes an upper air passage chamber, a lower air passage chamber, and a partition plate three disposed between the upper and lower air passage chambers. A pair of upper air passage ports for connecting the filter chamber are symmetrically arranged on the side of the upper air passage chamber, and a pair of lower air passage ports for connecting the filter chamber are symmetrically arranged on the side of the lower air passage chamber. A partition plate two is disposed between the two upper air passage ports in the upper air passage chamber, and the two lower air passage ports in the lower air passage chamber are interconnected.

[0014] As a further improvement to the above solution, the upper part of the filter cavity is provided with an upper air passage that matches the upper air passage of the rotating cylinder, and the lower part of the filter cavity is provided with a lower air passage that matches the lower air passage of the rotating cylinder; the outer side of the rotating cylinder is provided with a protrusion at the upper air passage of the rotating cylinder that matches the upper air passage of the filter cavity, and the edge of the protrusion is provided with a smooth edge.

[0015] As a further improvement to the above solution, a sponge block is provided inside the upper air passage chamber; a pad is provided at the bottom of the filter chamber; and a sealing cap is provided on the outside of both the air inlet and air outlet.

[0016] As a further improvement to the above solution, the loading and unloading component includes a stud with one end threaded to the connecting seat, the other end of the stud passing through a through hole and having an end plate at the bottom of the tank, and a torsion handle on the outside of the end plate.

[0017] As a further improvement to the above solution, the upper and lower air inlets of the rotating drum are breathable meshes with filter holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By setting up a switching structure, corresponding filter media, and independent gas absorption chambers, a single tank can be used for multiple purposes. At the same time, the switching mechanism is convenient and reliable to operate, significantly improving the utilization efficiency and safety performance of the filter.

[0020] 2. The circumferentially symmetrical and spaced filter chambers allow operators to complete the switching with just a quarter turn; at the same time, the raised design ensures a more secure and sealed rotation of the switching mechanism to the corresponding position.

[0021] 3. The distinguishing labels and label windows help staff quickly identify the current filter type; the loading and unloading mechanism securely connects the bottom of the rotating drum to the tank; it also allows for easy disassembly and replacement; and even when the studs are fully tightened in the connecting seat, the handle can still be used to rotate the drum.

The rotating plate 31 has a marking window 32 for exposing the distinguishing mark 16 when the rotating plate 31 is rotated.

[0038] like Figures 1-7 As shown, in a preferred embodiment of the above, the switching mechanism 3 includes a pair of vents 311 opened on the rotating plate 31 and respectively connected to the air inlet 41 and the air outlet 42. The rotating cylinder 33 is disposed below the rotating plate 31. The rotating cylinder 33 includes an upper air passage chamber 34, a lower air passage chamber 35, and a partition 331 disposed between the upper air passage chamber 34 and the lower air passage chamber 35.

At this time, the gas supplied from the outside first passes through the inlet port to the corresponding air inlet on one side of the inlet port, and then sequentially passes through the air inlet on the rotating cylinder and the air inlet on the filter chamber. The gas enters the lower gas chamber through the inlet, carbon dioxide absorbent material, lower air inlet of the filter chamber, and lower air inlet of the rotating cylinder. Then, it sequentially passes through the lower air inlet of the rotating cylinder, the lower air inlet of the filter chamber, the carbon dioxide absorbent material, the upper air inlet of the filter chamber, and the upper air inlet of the rotating cylinder on the other side of the lower gas chamber, and finally exits through the vent and outlet ports, completing the entire filtration and absorption process. When it is necessary to switch to the anesthetic gas absorption function, it is only necessary to rotate the switching mechanism one-quarter turn, and the upper air inlet and lower air inlet of the rotating cylinder will switch to the positions corresponding to the upper air inlet and lower air inlet of the filter chamber in the anesthetic gas absorption chamber.
