Description

Technical Field

[0001] This utility model relates to the field of laboratory mouse handling technology, and in particular to a portable and safe laboratory tool for handling mice. Background Technology

[0002] Mice are frequently used laboratory animals in teaching and research. Proper and standardized handling of mice is an essential skill for conducting successful animal experiments and a fundamental requirement of animal ethics. For securing mice, the common practice is to lift the mouse by its tail with your right hand and place it on the cage lid or other rough surface. As the mouse struggles and crawls forward, use your left thumb and forefinger to pinch the skin around its neck, placing the mouse in the palm of your left hand, with your ring and little fingers gripping its back and tail. This will completely immobilize the mouse.

[0003] However, different strains of mice often exhibit different behaviors. For example, mice with C57BL / 6 or ICR backgrounds are prone to aggression and jumping. Even experienced lab technicians using traditional bare-handed handling methods are at risk of being bitten by the mouse's neck, endangering their safety and affecting subsequent experimental progress. For beginners, even relatively docile strains present the same problem, making subsequent experiments impossible. Currently, one solution is to wear cotton or latex gloves, but commercially available mouse-handling gloves are generally quite thick, making it difficult for lab technicians to control the position when grasping the mouse's neck along its back and flexibly changing the mouse's position. Therefore, a portable and safe experimental tool for handling mice is needed to meet this requirement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing mouse-catching gloves, which make it difficult to control the position of the mouse and flexibly change its body position when worn. This invention proposes a portable and safe experimental tool for catching mice.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a portable and safe experimental apparatus for handling mice, including a glove. An auxiliary grasping mechanism is fixed to the thumb and index finger of the glove. The auxiliary grasping mechanism includes two magnetic strips and an Elizabethan collar. The two magnetic strips are fixed to the thumb and index finger of the glove, respectively. Two iron plates are fixed to the Elizabethan collar. The two iron plates are magnetically attracted to the two magnetic strips. Velcro A and Velcro B are fixed to the Elizabethan collar.

[0007] Preferably, the glove is a rubber glove, and the thumb and index finger of the glove are inlaid with fleece fabric, and the two magnetic strips are respectively fixed on the two pieces of fleece fabric.

[0008] Preferably, the Elizabethan collar is fixed with a protective mechanism.

[0009] Preferably, the protective mechanism includes two first fabric covers, both of which are fixed to the Elizabethan collar.

[0010] Preferably, the gloves are equipped with an anti-slip mechanism.

[0011] Preferably, the anti-slip mechanism includes a sleeve, which is fixed to the glove, and a second cloth cover is fixed to the sleeve, with an elastic ring fixed in the second cloth cover.

[0012] The present invention provides a portable and safe experimental tool for handling mice, which has the following advantages: When using this portable and safe experimental tool for handling mice, it is convenient to handle mice with different phenotypes, thereby ensuring the consistency and controllability of the mice's condition, improving the efficiency and safety of experimental operations, and increasing the accuracy of experimental data.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3A portable and safe experimental apparatus for handling mice includes a glove 1. An auxiliary grasping mechanism is fixed to the thumb and index finger of the glove 1. The auxiliary grasping mechanism includes two magnetic strips 6 and an Elizabethan collar 2. The two magnetic strips 6 are fixed to the thumb and index finger of the glove 1 respectively. The glove 1 is a rubber glove, and the thumb and index finger are both inlaid with fleece 7. The two magnetic strips 6 are fixed to the two fleece 7 pieces respectively. The glove 1 is 32cm long and 8cm wide. The thumb and index finger of the glove are made of fleece 7 that fits the hand and is 0.5mm thick, ensuring operational flexibility and allowing the Elizabethan collar 2 to be fixed in the desired position. The 1.5cm thick rubber glove 1 ensures that the mouse will not bite the experimenter if it jumps. Furthermore, the glove 1 has good fit and protection, eliminating the need for an inner powder-free latex glove, ensuring cleanliness and hygiene. After the experiment, it only needs to be rinsed and dried to achieve the purpose of cleaning, and it is reusable.

[0019] Two iron plates 5 are fixed to the Elizabethan collar 2, and the two iron plates 5 are magnetically attracted to two magnetic strips 6 respectively. Hook and loop fastener A 3 and hook and loop fastener B 4 are fixed to the Elizabethan collar 2. Through the magnetic attraction of the two iron plates 5 and the two magnetic strips 6, the Elizabethan collar 2 is fixed to the thumb and index finger of the glove 1. The opening direction of the Elizabethan collar 2 can be adjusted according to the needs of the experiment. The Elizabethan collar 2 is fixed into a circle by the mutual adhesion of hook and loop fastener A 3 and hook and loop fastener B 4. The length of the circle is between 1.0cm and 3.5cm to ensure that it is suitable for mice of different strains and different ages.

[0020] The Elizabethan collar 2 is equipped with a protective mechanism, which includes two first cloth covers 8. Both first cloth covers 8 are fixed to the Elizabethan collar 2. The arrangement of the two first cloth covers 8 ensures that the edge of the Elizabethan collar 2 is covered by the first cloth covers 8 when the Elizabethan collar 2 is placed around the neck of the mouse, thus preventing harm to the mouse's body. Furthermore, since the position of the Elizabethan collar 2 on the glove 1 is adjustable, the Elizabethan collar 2 can be used in two ways: with the opening facing forward and with the opening facing backward. The opening facing forward is suitable for intraperitoneal injection, tail vein injection, and other situations, while the opening facing backward is suitable for in vivo light recording, blood collection from the orbital venous plexus, and other situations, providing ample experimental operating space.

[0021] In use, the Elizabethan collar 2 is secured to the thumb and forefinger of glove 1 with the assistance of two iron plates 5 and two magnet strips 6, ensuring that the collar 2 can be manipulated through glove 1. The glove 1 is used to gently encircle the mouse's neck, and then the forefinger and forefinger, using Velcro A 3 and Velcro B 4, secure the collar 2 around the mouse's neck, ensuring it is firmly in place. After securing the mouse's head, the mouse can be grasped. The left thumb and forefinger pinch the mouse's ears and neck skin, placing the mouse in the palm of the left hand, and the ring and little fingers pinching the back skin and tail to completely immobilize the mouse. Because the mouse's neck is restricted, it will not bite the experimenter. The opening direction of the Elizabethan collar 2 can be adjusted according to the experimenter's experimental purpose. Various experimental procedures can then be performed, such as blood collection from the orbital venous plexus, drug administration via tail vein injection, and in vivo light recording. After the experiment, the Elizabethan collar 2 is removed, and the mouse is returned to its cage.

[0022] In addition, this portable and safe mouse-handling experimental tool can be used while the mouse is moving in the cage, which reduces the frequency of stress that occurs in traditional mouse-handling processes, reduces the probability of high-level paraplegia caused by directly grasping the mouse's neck, improves experimental efficiency, and increases the accuracy of experimental data.

[0023] Example 2: In Example 1, glove 1 is shorter and not as secure when worn, making it easy to fall off. (Refer to...) Figure 1 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the glove 1 is fixed with an anti-slip mechanism, which includes a sleeve 9, the sleeve 9 is fixed to the glove 1, and a second cloth cover 10 is fixed to the sleeve 9. An elastic band 11 is fixed in the second cloth cover 10. When the glove 1 is in use, the sleeve 9 is put on the arm and fixed to the arm by the elastic band 11, thereby ensuring the effectiveness of the glove 1 in use and preventing it from falling off.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
