[0049] The laboratory mouse anesthesia equipment of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0050] like Figure 1-Figure 12As shown, the laboratory mouse anesthesia equipment includes: a surgical fixing plate 1 for fixing mice during experimental surgery; an anesthesia shell 2 for anesthetizing mice before and during surgery; in order to facilitate the adjustment of the position of the anesthesia shell 2 relative to the surgical fixing plate 1, so that mice of different body sizes can use the same anesthesia equipment, the surgical fixing plate 1 is slidably connected to the anesthesia shell 2, and the position of the anesthesia equipment relative to the surgical fixing plate 1 is adjusted according to the body size of different mice, so as to ensure the amount of anesthetic inhaled by the mouse during the mouse surgery. Similarly, it can also conveniently meet the needs of the surgeon to adjust the distance of the anesthesia shell 2 according to the state of the mouse during the operation, and then adjust the dosage of the anesthetic ingested by the mouse, so as to ensure the smooth progress of the experimental surgery.

[0051] In order to ensure the release of the anesthetic inside the anesthesia shell 2, an air outlet 21 is provided at one end of the anesthesia shell 2, and a fixing rod 3 (the fixing rod 3 can be a threaded rod, which is threadedly connected to the surgical fixing plate 1) is fixedly connected to the upper side of the surgical fixing plate 1 outside the air outlet 21. After the mouse is anesthetized, one side of the mouse's nostril is placed close to the air outlet 21, so that the mouse can be guaranteed to take in a certain amount of anesthetic for a long time during the mouse surgery.

[0052] In order to extend the extension distance of the air outlet 21, and at the same time, when the mouse has an abnormal collision, the position of the air outlet 21 can be somewhat extended to ensure that the air outlet position of the air outlet 21 is close to the mouse, thereby improving the anesthesia effect. The air outlet 21 is fixedly connected with an anesthesia cylinder assembly 4.

[0053] In order to realize the telescopic rebound effect of the part of the anesthesia tube assembly 4 extending out of the air outlet 21, the anesthesia tube assembly 4 includes: an extension tube 41 extending out of the air outlet 21, a limiting sleeve 42 limiting the inner wall of the anesthesia shell 2, an extension sleeve 43 supporting the compression spring 44 outside the anesthesia shell 2, and a compression spring 44 supporting the extension sleeve 43. The extension tube 41 extends into the air outlet 21, and the limiting sleeve 42 is fixedly connected to the outer wall of the end extending into the air outlet 21 (preferably, the limiting sleeve 42 is threadedly connected to the outer wall of the extension tube 41), and the other end of the extension tube 41 is fixedly connected to the extension sleeve 43, and a compression spring 44 is arranged between the extension sleeve 43 and the outer wall of the anesthesia shell 2. The compression spring 44 supports the extension sleeve 43 to extend a certain distance, and the compression spring 44 is in a compressed state, supporting the extension sleeve 43 to be in an extended position.

[0054] When the mouse shakes abnormally, or the experimenter touches the extension sleeve 43 during the operation, the entire anesthesia cylinder assembly 4 can compress the compression spring 44 and shrink, and can recover naturally, ensuring that the relative distance between the anesthesia cylinder assembly 4 and the mouse remains unchanged, thereby ensuring the anesthetic effect of the mouse.

[0055] In order to cover the compression spring 44 and reduce the exposed size of the compression spring 44, it also includes: a protective sleeve 45, one end of which is fixedly connected to the end of the extension sleeve 43, and the protective sleeve 45 is sleeved on the outer wall of the compression spring 44. At the same time, in order to prevent the protective sleeve 45 from affecting the telescopic size of the extension tube 41, the length of the protective sleeve 45 is smaller than the length of the extension tube 41.

[0056] In order to satisfy the function of the surgical fixing plate 1 to fix the mouse during the operation and to limit and adjust the anesthesia shell 2, the surgical fixing plate 1 includes: a fixing plate body 11 for fixing the mouse and two guide plates 12 for adjusting the position of the anesthesia shell 2. One side of the fixing plate body 11 is fixedly connected to the guide plate 12, and the two guide plates 12 are connected to the anesthesia shell 2 by limiting the guide connection. The fixing rod 3 is fixedly connected to the upper side of the fixing plate body 11. In order to satisfy the sliding of the anesthesia shell 2, it can also be ensured that the anesthesia shell 2 will not separate from the guide plate 12. A guide protrusion 13 is provided on the side of the guide plate 12 close to the anesthesia shell 2, and guide grooves 22 are provided on both sides of the bottom of the anesthesia shell 2, and the guide protrusion 13 is slidably connected inside the guide groove 22.

[0057] In order to ensure that the position of the anesthesia shell 2 can be limited during the sliding process, that is, when the anesthesia shell 2 slides to the set position, it can be relatively fixed. A limiting component 5 is provided on the side of the guide plate 12 close to the anesthesia shell 2, and a limiting groove 23 is provided on the outer wall of the anesthesia shell 2. The limiting component 5 extends into the limiting groove 23 to limit the position of the anesthesia shell 2. The limiting component 5 and the limiting groove 23 are structurally adapted to ensure the limiting effect.

[0058] In order to facilitate the installation of the limit assembly 5 and to facilitate its extension, the experimenter can manually push the limit assembly 5 to slide. The guide plate 12 is provided with a limit cavity 24 on one side close to the anesthesia shell 2, and the limit assembly 5 is limit-connected inside the limit cavity 24.

[0059] The limiting assembly 5 includes: a guiding rod 51 for guiding, a positioning plate 52 for limiting the entire limiting assembly 5 in the limiting cavity 24, a limiting protrusion 53 for cooperating with the anesthesia shell 2 for limiting, and a pushing spring 54 for pushing the entire limiting assembly 5 out of the limiting cavity 24. One end of the guide rod 51 is fixedly connected to the limiting protrusion 53, and one end of the guide rod 51 close to the limiting protrusion 53 is threadedly connected to the positioning plate 52, and the pushing spring 54 is sleeved on the outer wall of the guide rod 51. The positioning plate 52 is pushed by the pushing spring 54, and the limiting protrusion 53 is extended along the limiting cavity 24 to limit the anesthesia shell 2.

[0060] The guide rod 51 extends into the bottom of the limiting cavity 24, and an installation slot 25 is provided on the lower side of the limiting cavity 24 through the positioning plate 52. The width of the installation slot 25 is greater than the thickness of the positioning plate 52, so that the positioning plate 52 can be installed inside the limiting cavity 24 along the installation slot 25, and the positioning plate 52 can slide inside the installation slot 25 (the positioning plate 52 can move along the length direction of the limiting cavity 24); the specific installation process is: the positioning plate 52 extends into the limiting cavity 24 along the installation slot 25, the guide rod 51 and the limiting protrusion 53 extend along the limiting cavity 24, the guide rod 51 passes through the threaded hole opened in the center of the positioning plate 52, and when the guide rod 51 is close to the external thread and threaded hole at one end of the limiting protrusion 53, the guide rod 51 is rotated and the limiting protrusion 53 is threadedly connected to ensure that the larger positioning plate 52 is smoothly installed.

[0061] In order to ensure that the positioning plate 52 does not rotate, the guide rod 51 can be threadedly connected to the positioning plate 52. The positioning plate 52 is a square plate, and the upper side of the installation slot 25 is a square structure, so that the installation slot 25 limits the rotation of the positioning plate 52.

[0062] In order to facilitate mice to enter the anesthesia shell 2, a mouse entrance hole 26 is provided at one end of the anesthesia shell 2 away from the air outlet 21, and a mouse door 6 is hinged inside the mouse entrance hole 26. The mouse is locked inside the anesthesia shell 2 by closing the mouse door 6.

[0063] The mouse after anesthesia can be conveniently taken out, and a cover plate 7 is hinged on the upper side of the anesthesia shell 2. The anesthesia shell 2 is opened through the cover plate 7, and the mouse anesthetized inside the anesthesia shell 2 is taken out, and the surgery is fixed by inserting the fixing rod 3.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
