Description

Technical Field

[0001] The utility model relates to the technical field of anesthesia machines, in particular to a filtering device for anesthesia machines. Background Art

[0002] The anesthesia machine delivers anesthetics into the patient's alveoli through a mechanical circuit, forming a partial pressure of anesthetic gas. After diffusing into the blood, it directly inhibits the central nervous system, thereby producing the effect of general anesthesia. When the anesthesia machine is in use, the gas inhaled by the patient is generally simply filtered through a filtering device so that the number of gas particles reaches the standard requirement to ensure the patient's breathing.

[0003] In a Chinese patent with publication number CN220110225U, a filter for an anesthesia machine is disclosed. Through the cooperation of a guide section and a guide groove, the gap between the upper shell and the lower shell is reduced, so that the upper shell and the lower shell can compress the sealing ring to improve the sealing effect, and the positioning pin passes through the first positioning hole and the second positioning hole to achieve locking. It is difficult for the two to move relative to each other, and the connection is convenient and reliable. However, when the above-mentioned filter for anesthesia machine is actually used, the upper and lower shells are generally pre-installed and then locked and fixed. However, when the filter is installed, the installation steps are relatively cumbersome, and it is difficult to quickly install the filter, which makes the filter more time-consuming and labor-intensive during installation, resulting in low installation efficiency of the filter device and affecting the rapid use of the filter device.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-Figure 4 A filtering device for an anesthesia machine shown includes:

[0027] The filter assembly 1 is used for filtering gas in an anesthesia machine. The filter assembly 1 includes an air inlet pipe 11 and an air outlet pipe 12, and the air inlet pipe 11 and the air outlet pipe 12 are combined to form a filter pipe; the structure and principle of the air inlet pipe 11 and the air outlet pipe 12 are both prior art, and specific reference can be made to the comparative document (publication number CN220110225U, patent name is a filter for an anesthesia machine), which will not be repeated here;

[0028] The disassembly assembly 2 is used for quickly disassembling the air inlet pipe 11 and the air outlet pipe 12. The disassembly assembly 2 comprises a threaded pipe 21 fixed to one end of the air inlet pipe 11 and an internal thread 22 provided in the air outlet pipe 12. The internal thread 22 is screwed and fixed to the threaded pipe 21. A storage cavity for placing filter cotton is formed between the threaded pipe 21 and the air inlet pipe 11. A mounting assembly for connecting the threaded pipe 21 to the threaded pipe 21 is provided in the air outlet pipe 12.

[0029] The installation component includes a sealing gasket 23 fixed in the air outlet pipe 12 and a guide cavity 27 opened at one end of the threaded tube 21, one end of the sealing gasket 23 is fixed with an annular frame 24 corresponding to the guide cavity 27, and the annular frame 24 and the guide cavity 27 are plugged and fixed, and a sealing component for closing it and the guide cavity 27 is provided on the annular frame 24; the sealing component includes an arc plate 26 slidably installed in the guide cavity 27 and an anti-stripping ring 25 fixed on the outside of the annular frame 24, and one end of the anti-stripping ring 25 extends into the guide cavity 27 and is fixedly connected to one end of the arc plate 26.

[0030] As can be seen from the above, when in use, the threaded tube 21 is screwed in along the internal thread 22. As the air inlet pipe 11 rotates, the end portion of the threaded tube 21 will squeeze the outside of the arc plate 26. At this time, the arc plate 26 is inserted into the guide cavity 27. Then, as the guide cavity 27 slides along the outside of the arc plate 26, the guide cavity 27 moves toward the anti-stripping ring 25, and the anti-stripping ring 25 and the guide cavity 27 are squeezed and deformed, so that the outside of the anti-stripping ring 25 is tightly against the inside of the guide cavity 27, and the threaded tube 21 is tightly fitted with the sealing gasket 23, thereby realizing the rapid installation of the air inlet pipe 11 and the air outlet pipe 12, and at the same time having a good seal with each other, thereby solving the problem that the installation steps of the existing filter are complicated and it is difficult to install the filter quickly, thereby improving the installation efficiency of the filter device and facilitating the rapid use of the filter device.

[0031] In addition, refer to Figure 1-Figure 5As shown, an ejection assembly 3 is provided in the storage chamber, and the ejection assembly 3 is used to resist the filter cotton. The ejection assembly 3 includes a movable ring 31 installed in the storage chamber and a sleeve 33 fixed at one end of the intake pipe 11, and the sleeve 33 is located in the storage chamber, and a connecting column 32 is fixed at one end of the movable ring 31, and the connecting column 32 is plugged into the sleeve 33, and an elastic assembly is provided in the sleeve 33 to support it and the connecting column 32; the elastic assembly includes a slide groove opened in the sleeve 33 and a spring 34 installed between the slide groove and the connecting column 32, and the connecting column 32 is located in the slide groove; an annular gasket 35 is also fixed at one end of the connecting column 32, and the annular gasket 35 is slidably connected to the slide groove, and the annular gasket 35 is fixed on the spring 34 relative to one end of the connecting column 32; a positioning groove corresponding to the connecting column 32 is also opened at one end of the movable ring 31, and the positioning groove and the connecting column 32 are fixedly connected.

[0032] Through the above technical solution:

[0033] When in use, by rotating the air inlet pipe 11, the threaded tube 21 is screwed together along the internal thread 22. At this time, the air inlet pipe 11 and the air outlet pipe 12 are disengaged, but the spring 34 is tightened and reset, thereby pushing the annular gasket 35 toward the side of the connecting column 32, and moving the annular gasket 35 along the slide groove. As the annular gasket 35 moves, it pushes the connecting column 32 to move synchronously along the slide groove, and then the length between the connecting column 32 and the sleeve 33 is extended. Subsequently, the moving ring 31 is pushed by the connecting column 32 to push the filter cotton in the access cavity outward, so that the filter cotton can be quickly taken out of the storage cavity, which can make it easier for medical staff to thoroughly clean and disinfect the filter device, thereby reducing the risk of cross infection, ensuring the normal operation of the anesthesia machine, and facilitating the patient's breathing.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
