Embodiment 1

[0028] Such as figure 1 As shown, the mouse liquid feeding auxiliary device includes a handle 3 and a handle 2 4, and the rear ends of the two handles are fixedly connected to the same claw torsion spring 1, that is, the rear ends of the handle 3 and the handle 2 4 are fixedly connected Two claws of the same claw torsion spring 1; a limiting plate 2 is set between the rear end of the handle and the claw torsion spring 1, and two waist holes are arranged on the limiting plate 2, and the two claws of the claw torsion spring 1 The claws pass through the corresponding waist holes respectively and are connected to the handles. Notches 11 are respectively provided on the inner surfaces of the two handles, and the notches 11 extend backward from the front end of the handle axially. The diameter of the large diameter of the accommodation cavity is not less than the waist circumference of the mouse 20, and the diameter of the small diameter of the accommodation cavity is not greater t...

Embodiment 2

[0036] The method for carrying out liquid feeding to mice using the device in Example 1, the steps include:

[0037] Step 1: grab the mouse 20 that meets the experimental requirements, and hold the handle of the aforementioned mouse liquid feeding auxiliary device in an unlocked state;

[0038] Step 2: Put the mouse 20 from the neck to the tail into the gap 11 between the handle 1 3 and the handle 2 4, the head of the mouse 20 is exposed, and press the handle with the right hand to make the handle 1 3 and the handle 2 4 Move towards the right position, stop applying force with the right hand, and place the handle flat on the operating table;

[0039] Step 3: Hold the hand-pinch inflator 5 and repeatedly and continuously perform the "pinch-release" operation, and control the time of each "pinch-release" operation to 2-3 seconds, and observe the temperature display terminal 6 at the same time , when a certain temperature display terminal 6 displays 35-38°C, stop pressing the ha...

Abstract

The invention provides an auxiliary device for liquid feeding of mice and a feeding method. The device includes two handles, the rear ends of the two handles are fixedly connected to the same claw torsion spring, and gaps are respectively arranged on the inner surfaces of the two handles. , the notch extends backward from the front end of the handle axially. When the two handles move toward each other to a suitable position, the notches on the two handles together form a cavity for accommodating the neck to the tail of the mouse, and the diameter of the large diameter part of the cavity is not less than The waist circumference of the mouse, the diameter of the small diameter part of the accommodation chamber is not greater than the diameter of the head of the mouse, and not smaller than the diameter of the neck of the mouse. The step of the feeding method includes using the aforementioned device to fix the mice and then feeding them. The present invention completely eliminates the strength error factor caused by artificially pinching the mouse, and solves the problem that the mouse suffers great stress when the mouse is fixed during the feeding process, and the stress difference of the mouse during different times of feeding is large. It is helpful to improve the accuracy of the experimental results.

Description

technical field [0001] The invention relates to a mouse experiment appliance, in particular to an auxiliary device for feeding mice with liquid and a method for feeding them. Background technique [0002] Mice have been used in experiments by humans as early as the 17th century, and have become one of the most widely used and most thoroughly studied mammalian experimental animals. In the research with mice as the experimental object, the feeding of liquid feed or medicine is mainly done by manually capturing and fixing the mice, and then feeding the related liquid feed or medicine, such as the operator pinches the mouse with his left hand and holds the feed with his right hand. A tube was inserted into the stomach of the mouse for gavage. However, there are many problems in feeding the mice after pinching and immobilizing them manually, including: the mice are not firmly fixed and often bite the operator; the feeding liquid is easy to overflow, which leads to inaccurate exp...
