Guinea pig fixer

Abstract

The utility model discloses a guinea pig fixing device which comprises a bottom plate and further comprises side plates symmetrically fixed to the bottom plate. The baffles are arranged at the two ends of the two side plates; the semi-circular grooves are formed in the lower end of the baffle plate; the vertical grooves are symmetrically formed in the two ends of the side plates. The guinea pigs with different sizes can be fixed by selecting the proper vertical grooves; and the baffle plates with the semicircular grooves in different sizes can be selected for fixing according to heart blood sampling or intragastric administration of the guinea pig. Meanwhile, when the fixing device is used, the upper portion of the guinea pig is completely exposed, heat can be effectively dissipated, and heat syncope of the guinea pig is prevented. And the fixing device can be conveniently cleaned through the excrement and urine discharge hole after the experiment is finished. The device can effectively improve the experimental operability of guinea pig heart blood sampling and gavage, and the application rate of the fixator is effectively improved through the semicircular grooves of multiple sizes and the multiple pairs of vertical grooves. The fixer is convenient to use and effective to operate, and is a more ideal fixer for blood sampling and gavage of the guinea pig heart in medical and pharmaceutical animal experiments.

Description

Technical Field

[0001] The utility model relates to the technical field of animal experimental equipment, in particular to a guinea pig fixer. Background Art

[0002] In medical and pharmaceutical animal research, guinea pigs serve as animal models and play a vital role in multidisciplinary scientific research, including immunology, pharmacology, and nutrition. Guinea pigs are docile and naturally timid. During experiments, such as oral administration or cardiac blood sampling, they may struggle violently. This not only increases the difficulty of the experiment but also causes stress in the guinea pigs, affecting the accuracy of the results, violating the ethical standards of laboratory animal welfare, and even causing harm to the experimenters. Therefore, for the smooth conduct of the experiment and the safety of the experimenters, guinea pigs must be restrained.

[0003] In existing technologies, guinea pig holders can secure guinea pigs, thus protecting the safety of both the guinea pigs and the experimenters. However, 1. Some holders are not conducive to experimental operations. For example, when drawing blood from the heart of a guinea pig, the heart cannot be exposed, making it inconvenient for the experimenter to perform the blood collection operation. For example, when administering medication through the stomach, the mouth cannot be exposed, or the fixed position makes gavage inconvenient and may even cause the guinea pig to suffocate and die. 2. The holders are fixed in size and inflexible. Because guinea pigs vary in size, if the guinea pig is too large, the space is too small and the restraint is too tight, which does not meet the requirements of animal welfare ethics and may even cause death. If the guinea pig is too small, the space is too large, and the loose fixation causes the guinea pig to struggle violently, affecting the accuracy of the experimental results and even causing injury to the experimenter. Utility Model Content

[0004] In view of the above defects or improvement needs of the prior art, the present invention provides a guinea pig fixator, the purpose of which is to flexibly fix the guinea pig so as to better perform cardiac blood sampling or intragastric drug administration operations.

[0005] To achieve the above-mentioned purpose, the technical solution adopted is: a guinea pig fixer includes: a bottom plate; and side plates symmetrically fixed on the bottom plate; a baffle arranged between the two side plates, with a semicircular groove opened at the lower end of the baffle; and vertical grooves symmetrically opened at both ends of the side plates.

[0006] In order to facilitate the fixation of different parts of the guinea pig, the baffle is divided into semicircular grooves of various sizes.

[0007] In order to facilitate the fixing of guinea pigs of different sizes, the side panels are provided with a plurality of vertical slots arranged at equal distances (with a spacing of 2 cm).

[0008] In order to facilitate the discharge of guinea pig excrement and the cleaning of the guinea pig holder, the bottom plate is provided with a feces discharge hole.

[0009] The length of the guinea pig fixer is greater than 25 cm. The body length of an adult guinea pig is approximately 15 to 25 cm. The length of the guinea pig fixer is greater than 25 cm, which can meet the fixation requirements of guinea pigs of different sizes. The semicircular groove at the lower end of the baffle has a radius of 2, 3, and 4 cm for the front baffle (3) and a radius of 5, 6, and 7 cm for the rear baffle (6). This can meet the fixation requirements of guinea pigs of different sizes and different parts.

[0010] The beneficial effects of the above solution are as follows: The guinea pig holder is first placed on the base plate. Depending on the size of the guinea pig, a baffle is placed into a matching slot to secure the upper armpit area. Another baffle is placed into a matching vertical slot to effectively secure the abdomen and lower armpit area, preventing the guinea pig from struggling. The holder fully exposes the guinea pig's chest, facilitating palpation of the strongest heartbeat.

[0011] The guinea pig holder is designed to first place the guinea pig on a base plate. Depending on the size of the guinea pig, a baffle is placed into a matching vertical slot to secure the neck and head. Another baffle is placed into a matching vertical slot to secure the abdomen, lower limbs, and armpits, preventing the guinea pig from struggling. The holder effectively secures the head. Once the holder is erected, gavage can be performed. One person can perform the gavage operation, allowing constant monitoring of the guinea pig's chewing and swallowing movements to prevent suffocation during gavage.

[0012] The fixator can fix guinea pigs of different sizes, effectively improving the application rate of the fixator, improving the comfort of the guinea pigs, and preventing the guinea pigs' stress reaction from affecting the accuracy of the experimental results. BRIEF DESCRIPTION OF THE DRAWINGS
