[0022] Example 1, by Figure 1-5 A portable mouse nebulization anesthesia device is provided, comprising a base 1 and a nebulizer 6. A displacement structure 2 is fixedly installed on the top of the base 1, a telescopic frame 3 is installed on the top of the displacement structure 2, a connecting rod 4 is fixed on the top of the telescopic frame 3, and a mounting frame 5 is fixed at the front end of the connecting rod 4. The nebulizer 6 is embedded in the mounting frame 5, and a medicine cup 61 is detachably installed on the top of the nebulizer 6. A mouse mask 62 is fixed at the position of the nebulization nozzle of the medicine cup 61.

[0023] In practical use, the device is placed on a table near the experimental table. First, the medicine cup 61 of the nebulizer 6 is removed, and the anesthetic is injected into the medicine cup 61. Then, the medicine cup 61 is installed on the nebulizer 6, and the mouse mask 62 is embedded and installed into the nebulizing nozzle of the medicine cup 61. The mouse mask 62 has a sloping cup bottom groove design to accommodate mice of different sizes. Then, the nebulizer 6 is installed on the mounting frame 5. The experimenter holds the mouse and places it on the experimental table, puts the mouse's head into the mouse mask 62, and then starts the nebulizer 6 to atomize the anesthetic and spray it out through the mouse's mouth and nose for rapid anesthesia.

[0024] The base 1 has a friction pad fixed to its bottom. The friction pad is made of silicone or rubber, which provides greater friction when placed on a table and makes it less likely to tip over.

[0025] In this embodiment, the telescopic frame 3 includes a telescopic cylinder 31 that moves on the movable block 23. The top of the telescopic cylinder 31 is provided with a telescopic groove. A telescopic rod 33 is inserted into the telescopic groove and fixedly connected to the connecting rod 4. An adjusting bolt 32 is threadedly connected to the outer side of the top of the telescopic cylinder 31. The adjusting bolt 32 is threaded through the telescopic cylinder 31 and contacts and limits the telescopic rod 33.

[0026] Specifically, the height is adjusted by the telescopic frame 3, the adjusting bolt 32 is loosened, the telescopic rod 33 is pulled out from the telescopic cylinder 31 to adjust the height, and then the adjusting bolt 32 is tightened to the limit so that the mouse mask 62 on the nebulizer 6 is level with the mouse's head on the experimental table.

[0027] In this embodiment, the mounting bracket 5 includes a mounting plate 51 that is vertically fixed to the connecting rod 4. The mounting plate 51 is slidably connected to two elastic telescopic limiting structures 52 on both sides. A lower U-shaped plate 53 is fixed to the bottom of the mounting plate 51. The atomizer 6 is embedded between the two elastic telescopic limiting structures 52 and the lower U-shaped plate 53 for limitation. The elastic telescopic limiting structures 52 on both sides of the mounting plate 51 are pulled apart so that the distance between them is greater than the width of the atomizer 6. The atomizer 6 is placed on the lower U-shaped plate 53 and contacts the mounting plate 51. Then the two elastic telescopic limiting structures 52 are released, and the two elastic telescopic limiting structures 52 clamp and fix the atomizer 6.

[0028] In this embodiment, the elastic telescopic limiting structure 52 includes a spring groove 522 formed inside the mounting plate 51. A displacement rod 523 is provided inside the spring groove 522. One end of the displacement rod 523 movably passes through the mounting plate 51 and is fixed with a side limiting plate 521. The other end of the displacement rod 523 is fixed with a blocking plate 5231. A limiting spring 524 is sleeved on the outside of the displacement rod 523 and contacts the blocking plate 5231 and the inside of the spring groove 522.

[0029] In Example 2, based on Example 1, the displacement structure 2 includes a movable seat 21 fixed on the base 1. The top of the movable seat 21 is provided with a movable groove 22. A movable block 23 is slidably connected in the movable groove 22. The movable groove 22 has a convex cross-section, and the movable block 23 has an I-shaped cross-section. A load-bearing block is installed in the rear of the base 1.

[0030] Specifically, if the mouse is fixed on the experimental table and there is a distance between the mouse mask 62 and the mouse's head, the telescopic frame 3 can be grabbed and pushed forward to move the moving block 23 in the moving groove 22, so that the mouse mask 62 covers the mouse's head. The nebulizer 6 is then activated to spray the anesthetic, and the mouse inhales the nebulized anesthetic through its mouth and nose for rapid anesthesia.

[0031] In this embodiment, a nebulizer 6 of model UN101 is used. Its principle is as follows: compressed air is used to create a high-speed airflow through a narrow tube. This airflow generates negative pressure at the tube outlet, causing the liquid to be sprayed onto an obstruction (such as a baffle). Under high-speed impact, the liquid splashes outwards, forming a mist of microparticles that are then expelled from the outlet tube. These microparticles are subsequently inhaled into the patient's respiratory tract, providing a therapeutic effect. This nebulizer is an existing product, and its working principle is well-known to those skilled in the art and is common knowledge, requiring no further explanation.

[0032] Working principle:

[0033] When using the device, place it on a table near the experimental table. First, remove the medicine cup 61 from the nebulizer 6, inject the anesthetic into the medicine cup 61, then install the medicine cup 61 onto the nebulizer 6, and embed the mouse mask 62 into the nebulizer nozzle of the medicine cup 61. The mouse mask 62 has a sloping cup bottom groove design to meet the needs of mice of different sizes.

[0034] Then, install the atomizer 6 onto the mounting bracket 5, pull open the elastic telescopic limiting structures 52 on both sides of the mounting plate 51, that is, grasp the side limiting plate 521 and pull the displacement rod 523 out of the spring groove 522. The displacement rod 523 drives the blocking plate 5231 to move and compress the limiting spring 524 to store force. After the two side limiting plates 521 are pulled out, the distance between them is greater than the width of the atomizer 6. Place the atomizer 6 on the lower U-shaped plate 53 and make contact with the mounting plate 51. Then release the two side limiting plates 521. The limiting spring 524 rebounds and drives the displacement rod 523 back to its original position, so that the two side limiting plates 521 clamp and fix the atomizer 6.

[0035] Next, adjust the height by using the telescopic frame 3, loosen the adjusting bolt 32, pull the telescopic rod 33 out of the telescopic cylinder 31 to adjust the height, and then tighten the adjusting bolt 32 to limit the position so that the mouse mask 62 on the nebulizer 6 is level with the mouse's head on the experimental table.

[0036] The experimenters placed the mouse on the experimental table, put the mouse's head into the mouse mask 62, and then activated the nebulizer 6 to spray the anesthetic into the mouse's mouth and nose for rapid anesthesia.

[0037] If the mouse is fixed on the experimental table and there is a distance between the mouse mask 62 and the mouse's head, the telescopic frame 3 can be grabbed and pushed forward to move the moving block 23 in the moving groove 22 so that the mouse mask 62 covers the mouse's head. The nebulizer 6 is then activated to atomize and spray the anesthetic, and the mouse inhales the atomized anesthetic through its mouth and nose for rapid anesthesia.

[0038] In summary, this device consists of a support frame and an atomizer 6. The overall structure is relatively small and easy to carry. The support frame can hold atomizers 6 of different sizes, and the height can be adjusted via the telescopic frame 3 to suit different scenarios and height requirements. The atomizer 6 can atomize anesthetic drugs, allowing mice to inhale the anesthetic through their mouth and nose without intraperitoneal injection. This allows for anesthesia during the experiment, ensuring a constant level of anesthesia throughout the experiment. After the experiment, the animals can quickly recover and move freely.
