Then anesthetic gas can be introduced through the air inlet pipe and directly enters the oral cavity of the rat through the air inlet pipe, the fixing ring, the communicating pipe, the ventilating ball and the ventilating hole, and the problem that the anesthetic effect is affected due to anesthetic gas leakage is solved.

Description

Technical Field

[0001] This utility model relates to the field of animal anesthesia mask technology, specifically to a novel rat anesthesia mask. Background Technology

[0002] With the development of medical research, more and more medical research institutions need to use animals for related studies. Rat animal experiments are increasingly used in practice. However, due to the cone-shaped structure of rodent faces, anesthesia masks cannot fit the mouths or heads of different animals, and are often not securely fixed. Furthermore, existing animal masks, due to their rigid structure, are particularly difficult to fit snugly when the animal is fixed in a neck-flexed position on a stereotaxic apparatus due to limited space below, leading to anesthetic gas leakage and affecting the anesthesia effect. Therefore, this application proposes a novel rat anesthesia mask to solve the above problems. Utility Model Content

[0003] This invention provides a novel rat anesthesia mask to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A novel rat anesthesia mask includes an air inlet tube, one end of which is fixedly connected to a fixing ring. A connecting tube is fixedly connected to the outside of the fixing ring, and one end of the connecting tube is fixedly connected to a venting balloon. Multiple ventilation holes are formed on the outer surface of the venting balloon. The venting balloon is placed inside the rat's mouth. A soft mask is fitted over the fixing ring and the venting balloon. The air inlet tube, fixing ring, connecting tube, and venting balloon are internally connected. Anesthetic gas is introduced through the air inlet tube and flows out through the ventilation holes into the rat's mouth.

[0006] A further improvement of this utility model is that the fixing ring is circular, and a notch for engaging the rat's lower incisors is provided in the middle of the fixing ring.

[0007] A further improvement of this utility model is that a rigid mask is fixedly connected to the outer surface of the air intake pipe, one side of the rigid mask is fixedly connected to a soft mask, the soft mask covers the fixing ring and the air inlet, and one side of the soft mask has a sleeve opening.

[0008] A further improvement of this utility model is that the soft face mask is made of a soft, transparent material.

[0009] A further improvement of this utility model is that the hard mask has multiple air vents.

[0010] A further improvement of this utility model is that: multiple straps are fixedly connected to the soft face mask near the opening.

[0011] A further improvement of this utility model is that two matching Velcro straps are provided on the two straps.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] This invention provides a novel rat anesthesia mask. When anesthetizing a rat, the rat's head is first passed through the opening into the soft mask. Then, a venting balloon is placed inside the rat's mouth, and the rat's lower incisors are locked in the slot in the middle of the fixing ring. With the help of the straps, the soft mask is fixed to the rat. Then, anesthetic gas can be introduced through the air inlet tube. The anesthetic gas enters the rat's mouth directly through the air inlet tube, fixing ring, connecting tube, venting balloon, and vent hole, avoiding the problem of anesthetic gas leakage that would affect the anesthetic effect.

[0019] The present invention will be further described in detail below with reference to embodiments:

[0020] Example:

[0021] like Figure 1-4As shown, this utility model provides a novel rat anesthesia mask, including an air inlet tube 1. One end of the air inlet tube 1 is fixedly connected to a fixing ring 7, which is used to fix the rat's lower incisors. A connecting tube 11 is fixedly connected to the outside of the fixing ring 7. One end of the connecting tube 11 is fixedly connected to a venting balloon 8. Multiple ventilation holes 9 are opened on the outer surface of the venting balloon 8. The venting balloon 8 is placed in the rat's oral cavity. A soft mask 4 is fitted over the fixing ring 7 and the venting balloon 8. The air inlet tube 1, the fixing ring 7, the connecting tube 11 and the venting balloon 8 are internally connected. Anesthetic gas is introduced through the air inlet tube 1 and flows out through the ventilation holes 9 into the rat's oral cavity.

[0022] When anesthetizing rats, first place the rat's head inside the soft mask 4, then place the balloon 8 into the rat's mouth, and secure the rat's lower incisors to the fixing ring 7. This allows the anesthetic gas to be injected directly into the rat's mouth, avoiding leakage of anesthetic gas due to an unsecured anesthesia mask, which could affect the anesthetic effect.

[0023] Furthermore, the fixing ring 7 is circular, and a notch 10 for engaging the rat's lower incisors is provided in the middle of the fixing ring 7. The rat's lower incisors are engaged in the notch 10, and the balloon 8 is placed in the rat's mouth, which can directly inject anesthetic gas into the rat's mouth, reducing the possibility of leakage.

[0024] Furthermore, a rigid mask 2 is fixedly connected to the outer surface of the air inlet pipe 1. One side of the rigid mask 2 is fixedly connected to a soft mask 4. The soft mask 4 covers the fixing ring 7 and the balloon 8. A sleeve 6 is opened on one side of the soft mask 4. The rat's head passes through the sleeve 6 and is placed inside the soft mask 4. The balloon 8 is placed inside the rat's mouth. Through the ability of the soft mask 4 to be arbitrarily shaped and bent, a regional seal is formed on the rat's head, reducing the leakage of anesthetic gas.

[0025] Furthermore, the soft mask 4 is made of soft, transparent material, which makes it easy for the soft mask 4 to fit the rat's head and form a local seal.

[0026] Furthermore, the rigid mask 2 has multiple air vents 3 to ensure the rat's normal breathing.

[0027] Furthermore, multiple straps 5 are fixedly connected to the side of the soft mask 4 near the opening 6 to facilitate the fixation of the soft mask 4 to the rat.

[0028] Furthermore, the two straps 5 are provided with two matching Velcro straps, and the straps 5 can be fixed by Velcro straps, buckles or other methods.

[0029] The working principle of this novel rat anesthesia mask is explained in detail below.

[0030] like Figure 1-4As shown, when anesthetizing rats, the rat's head is first passed through the opening 6 and into the soft mask 4. Then, the air inlet 8 is placed inside the rat's mouth, and the rat's lower incisors are locked in the slot 10 in the middle of the fixing ring 7. With the help of the strap 5, the soft mask 4 is fixed to the rat. Then, anesthetic gas can be introduced through the air inlet tube 1. The anesthetic gas enters the rat's mouth directly through the air inlet tube 1, fixing ring 7, connecting tube 11, air inlet 8, and air vent 9, avoiding leakage of anesthetic gas and affecting the anesthetic effect.
