Description

Technical Field

[0001] This utility model relates to the field of animal medical auxiliary equipment technology, specifically to an anesthesia nasal mask suitable for oral operations on mice. Background Technology

[0002] Animal experiments are an important research tool in basic research on various diseases. Anesthesia of laboratory animals is a fundamental and crucial part of ensuring the smooth conduct of experiments. With increasing attention to the welfare and ethics of laboratory animals, many traditional anesthesia methods and drugs are gradually being phased out. In research on oral, pharyngeal, and tracheal diseases, existing mouse anesthesia masks cannot meet the needs of delicate oral and pharyngeal manipulations. Currently, there is a lack of a dedicated and safe anesthesia mask that can be used for both oral and pharyngeal manipulations.

[0003] Intraperitoneal injection of anesthetic drugs cannot precisely control the dosage, depth of anesthesia, and duration of anesthesia, affecting the accuracy and reliability of experimental data. The drugs used are highly toxic, causing significant damage to the liver and kidneys of experimental animals, potentially leading to unnecessary suffering or even death. It also hinders the operator's ability to monitor various physiological indicators. While the cone-shaped mouse anesthesia mask commonly used in gas anesthesia allows for controllable concentration and duration of anesthetic gas, its design, which completely covers the mouse's mouth and nose, impedes oral procedures such as gingival injection, laryngeal administration, implantation in the upper and lower jaws, and endotracheal intubation. Furthermore, mice recover quickly after brief removal of the mask, resulting in insufficient time for manipulation, and existing anesthesia masks cannot address the problem of excess anesthetic gas recovery, posing a potential threat to the health of experimental personnel. Utility Model Content

[0004] The purpose of this invention is to provide an anesthesia nasal mask suitable for oral manipulation in mice, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anesthesia nasal mask suitable for oral operations in mice, comprising a sleeve and a transparent nasal mask. A screw channel is provided at the axis of the sleeve, and a fixed screw is movably connected to the inner side of the screw channel. A screw hole is provided at one right end of the fixed screw, and a stainless steel wire ring is fixedly connected to the screw hole through the screw. A rotating screw is movably connected to the other side of the fixed screw, and the rotating screw passes through the sleeve and is movably connected to the fixed screw. An air supply tube is fixedly connected to the lower outer side of the sleeve, and the air supply tube is fixedly connected to the transparent nasal mask.

[0006] Preferably, the transparent nose mask has an opening on the right side, and the bottom of the transparent nose mask has outward protrusions arranged longitudinally. The top protrusion matches the muzzle of the experimental mouse, and the bottom protrusion matches the face of the experimental mouse. The muzzle of the top protrusion includes the area from the nose to the incisors, and the facial area of ​​the bottom protrusion includes the area from the nose to the parietal bone.

[0007] Preferably, the transparent nasal mask has an exhaust chamber inside, and an exhaust pipe is fixedly connected to the lower side of the transparent nasal mask, with the exhaust chamber connected to the exhaust pipe.

[0008] Preferably, a one-way exhaust valve is installed on the lower end face of the exhaust chamber, and a filter screen is fixedly connected to one side of the one-way exhaust valve.

[0009] Preferably, a malleable silicone ring pad is provided inside the right opening of the transparent nose mask.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a transparent nasal mask to cover the muzzle and face of a mouse. After loosening the screw, the fixing screw is pushed forward to place a stainless steel wire ring over the mouse's incisors. Pulling the fixing screw backward and tightening the screw secures the transparent nasal mask in place. Anesthetizing gas is delivered into the nasal mask through the gas inlet tube, allowing for precise control of the gas concentration. Under anesthesia, surgical procedures can be performed by opening the incisors at the lower jaw. The flexible silicone ring pad of the nasal mask ensures internal airtightness. Excess anesthetic gas is discharged through a one-way exhaust valve to the exhaust chamber and then collected in an anesthetic gas collection bottle via the exhaust pipe. This invention features a simple structure. During use, the stainless steel wire ring stably covers the mouse's incisors, and the transparent nasal mask provides a sealed interior, allowing for continuous anesthesia and preventing excessive anesthetic dosage from affecting the mouse's health. It facilitates procedures performed by researchers in the mouth, throat, and trachea, preventing rapid mouse awakening. Excess gas can be recovered, protecting the health of researchers.
