Flexible constraint rack for small animal mouth and nose exposing

Abstract

The invention provides a flexible constraint rack for small animal mouth and nose exposing, which comprises a bottom bracket, an external fixation connector and a flexible screen frame, wherein the front end of the bottom bracket is connected with the external fixation connector of an internal air inlet pipe to provide suction gas to a small animal, a mouth-and-nose exposing air chamber with a circle of expiration air holes is arranged inside the external fixation connector, the interior of the external fixation connector can accommodate the head of the small animal under a breathing trial, fixing bolts at the edge of the two sides of the bottom bracket can be used for fixing a fixed tank and firmly mounting the flexible screen frame well, the small animal is fixed between the bottom bracket and the flexible screen frame, the flexible constraint net on the flexible screen frame can constrain the body of the small animal, a neck fixing hoop is used for fixing the neck of the small animal into a neck fixing and clamping hole, the tail of the small animal can go through the tail fixing and clamping hole, and excreta can be discharged into an excrement collection box from the excretory opening of the bottom bracket. The flexible constraint rack for small animal mouth and nose exposing has the benefits as follows: the small animal can be quickly fixed, gas leakage is avoided, the small animal is enabled to be comfortable and have no bad consequences of dyspnoea, struggling and the like, and the flexible constraint rack can be widely used in scientific researches to respiratory disease pathology and medicine development.

Description

technical field [0001] The invention provides a flexible restraining frame for small animals with mouth and nose exposed. Background technique [0002] In recent years, the use of some small animals such as rats, mice, and guinea pigs for respiratory experiments to study the effects of respiratory drugs and air pollutants on humans has been vigorously developed. At present, most of these small animal respiratory experiments are only The small animal can be tied up with a hose or rope and simply put the breathing mask on its nose and connected to the nebulizer through a hose. There is no good way to fix the small animal, and sometimes the tightness of the tie affects the small animal's breathing and normal physiological limits. , Sometimes if the binding is not tight, it will cause escape in the middle. The leakage and laxness of the breathing mask will cause the inaccuracy of the breathing test and pollute the environment. Most of the small animal holders used are made of r...

[0002] In recent years, the use of some small animals such as rats, mice, and guinea pigs for respiratory experiments to study the effects of respiratory drugs and air pollutants on humans has been vigorously developed. At present, most of these small animal respiratory experiments are only The small animal can be tied up with a hose or rope and simply put the breathing mask on its nose and connected to the nebulizer through a hose. There is no good way to fix the small animal, and sometimes the tightness of the tie affects the small animal's breathing and normal physiological limits. , Sometimes if the binding is not tight, it will cause escape in the middle. The leakage and laxness of the breathing mask will cause the inaccuracy of the breathing test and pollute the environment. Most of the small animal holders used are made of rigid materials such as all-plastic materials or plexiglass. Although it is convenient for animal fixation and breathing experiments, the holders made of such rigid materials may not be easy to push when fixing small animals. Strictly cause gas leakage in the head, or small animals cannot move after being pushed, resulting in dyspnea. If the restraint time is longer, the small animals struggle with discomfort, causing endocrine disorders such as blood pressure, heart rate, and body temperature rise, and some may even die during the experiment. The insurmountable shortcoming of adopting rigid restraints for small animals seriously interferes with the results of breathing experiments, affects the development of such scientific research, and has become a major technical problem at present. Any gas leakage from its head can allow the small animal to move its body properly and change its posture during the experiment, so as to facilitate the expansion of the lungs and breathe comfortably without temperature accumulation, so that the blood pressure and heart rate will not be caused by the small animal's difficulty in breathing and struggling. There is an urgent need for a special small animal mouth and nose exposure flexible restraint frame for endocrine disorders such as body temperature rise and adverse consequences of death during the experiment
