One side of the bottle mouth is communicated with an anesthesia machine port, and the other side is communicated with a threaded pipe port. A partition is fixedly installed between the bottle body and the bottle mouth. One end of the top of the partition is fixedly connected to the top inner wall of the bottle mouth, and the bottom end is suspended in the inner cavity of the bottle body. The inner cavity between the bottle body and the bottle mouth is divided into a U-shaped gas flow channel by the partition; a microporous filter membrane is inserted and installed in the inner cavity of the threaded pipe port; an adsorbent is filled in the inner cavity of the bottle body.

[0003] The above artificial nose has the function of heat and humidity exchange, is simple and convenient to use. This filter is for single person and single can, and is replaced after use, which can avoid the possibility of cross-infection caused by repeated and long-term use by multiple patients. At the same time, it can reduce the workload of medical staff, improve the clinical work efficiency, and also increase the filtering function, which can filter viruses and bacteria.

[0032] The following will describe in detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0033] Please refer to Figures 1 to 8 As shown, the embodiment of the present utility model provides a disposable respiratory anesthesia filter, including a bottle body 1. The top of the bottle body 1 has a bottle mouth 101. One side of the bottle mouth 101 is communicated with an anesthesia machine port 103, and the other side is communicated with a threaded tube port 104. Sealing covers 111 are detachably installed on both the anesthesia machine port 103 and the threaded tube port 104. A partition board 102 is fixedly installed between the bottle body 1 and the bottle mouth 101. One end of the top of the partition board 102 is fixedly connected to the top inner wall of the bottle mouth 101, and the bottom end is suspended in the inner cavity of the bottle body 1. The inner cavity between the bottle body 1 and the bottle mouth 101 is divided into a U-shaped gas flow channel by the partition board 102. A filter membrane 112 is inserted and installed in the inner cavity of the threaded tube port 104. The inner cavity of the bottle body 1 is filled with an adsorbent 105. In this embodiment, the adsorbent 105 adopts spiked spherical calcium lime particles. The surface area of the spiked spherical particles is larger than that of the traditional columnar calcium lime particles. The diameter of the spherical particles is 3-4 mm. Compared with the columnar particles, the size is more uniform and the gap is more uniform, ensuring that the air flow passes smoothly and evenly, and contacting with carbon dioxide more fully. The hardness of the spherical particles reaches about 10 N, which is twice the hardness of the columnar particles, and there is less dust during transportation and use, effectively protecting the anesthesia machine and patients.

[0034] Upper water-absorbing sponges 106 and lower water-absorbing sponges 107 are respectively laid on the top and bottom of the adsorbent 105. The operation principle of the artificial nose of the present application is the same as that of the disposable respiratory anesthesia filter disclosed in the Chinese patent with the publication number CN220938730U, and will not be elaborated here.

[0035] In this embodiment, the bottom of the bottle body 1 is open, and a bottom plate 2 is detachably installed at the bottom of the bottle body 1. Among them, an internal thread 110 is provided on the inner wall of the lower end of the bottle body 1, a boss 204 is fixedly connected to the top of the bottom plate 2, a sealing plate 203 is fixedly connected to the top of the boss 204, an external thread is provided on the side of the sealing plate 203, and the sealing plate 203 is threadedly and fixedly installed inside the bottle body 1. The top of the bottom plate 2 abuts against the bottom of the bottle body 1. By adopting a threaded installation form, the sealing plate 203 is fixed inside the bottle body 1. When it is necessary to pour out the adsorbent 105 inside the bottle body 1, only need to screw out the sealing plate 203 from the bottle body 1, then the bottle body 1 can be separated from the adsorbent 105, thereby realizing the function of medical waste classification and recycling.

[0036] In this embodiment, the thickness of the sealing plate 203 is 2 mm - 5 mm, the thickness of the boss 204 is 1 mm - 3 mm, and the thickness of the bottom plate 2 is 3 mm - 6 mm. Under the condition of ensuring that the bottom of the bottle body 1 can be sealed, the height of the entire artificial nose is effectively reduced. In order to prevent the sealing plate 203 from being easily screwed out of the bottle body 1, a loosening prevention component is provided on the boss 204. The loosening prevention component includes an elastic plastic pawl 205. A stepped groove 109 is provided at the bottom of the bottle body 1, and a plurality of ratchet teeth 108 are fixedly connected to the inner wall of the stepped groove 109. One end of the elastic plastic pawl 205 is fixed on the boss 204, and the movable end of the elastic plastic pawl 205 can abut against the ratchet teeth 108 when the bottom plate 2 rotates counterclockwise. Among them, no less than two groups of elastic plastic pawls 205 are provided.

[0037] Specifically, a breaking notch 2051 is provided at one end of the elastic plastic pawl 205 close to the boss 204. By providing the breaking notch 2051, when it is necessary to screw out the sealing plate 203 from the bottle body 1, only need to rotate the bottom plate 2 counterclockwise with force. The breaking notch 2051 of this elastic plastic pawl 205 is squeezed, resulting in the elastic plastic pawl 205 breaking at the breaking notch 2051, so that the elastic plastic pawl 205 releases the limit on the ratchet teeth 108, and then the sealing plate 203 can be smoothly screwed out of the bottle body 1.

[0038] Specifically, in order to facilitate the rotation of the bottom plate 2, anti-slip lines 201 are provided on the side of the bottom plate 2.

[0039] Specifically, a pointing mark 202 is provided at the bottom of the bottom plate 2. By providing the pointing mark 202, it is convenient for the operator to intuitively know in which direction to rotate to screw out or tighten the sealing plate 203.

[0040] Specifically, in order to facilitate observing the color change of the adsorbent 105 inside the bottle body 1 during use, the bottle body 1 is a transparent plastic bottle body.

[0041] The above description shows and describes several preferred embodiments of the present utility model. However, as previously mentioned, it should be understood that the present utility model is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in the relevant field. And any alterations and changes made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
