Technical Field

[0001] This utility model relates to the field of animal experimental equipment technology, specifically to a mouse restraint device to prevent bites. Background Technology

[0002] Mice are commonly used to observe the effects of drugs, test the toxicity, pharmacokinetics and efficacy of new drugs, screen potential therapeutic drugs, and evaluate their performance in vivo. In animal experiments for medical research on mice, drugs are usually injected into mice intravenously. Before the injection, the mice need to be restrained to prevent them from struggling. During the restraint process, there is a risk of mice biting the experimenters.

[0003] Existing mouse restraint devices mostly involve fixing the mouse by binding its limbs to the experimental table. In essence, this means that the experimenter holds the mouse's paws with their bare hands and binds them one by one. Throughout this process, there is still the risk of being scratched or bitten by the mouse, increasing the risk of injury to the experimenter. Utility Model Content

[0004] The purpose of this invention is to overcome the problems in the prior art and provide an anti-bite auxiliary mouse fixation device that can quickly fix laboratory mice and prevent them from scratching or biting laboratory personnel, thus ensuring the safety of laboratory personnel.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. Words such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “inner,” “outer,” “upper,” “lower,” “far,” “near,” “front,” and “back” are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] The accompanying drawings in this invention are not strictly drawn to scale; the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in this invention are merely structural schematic diagrams.

[0019] The anti-bite auxiliary mouse restraint device provided by this utility model is as follows: Figure 1-4 and Figure 11-12 The device includes a placement platform 1, a restraint net 2 laid on the surface of the placement platform 1, which can be rolled into a net tube for wrapping up laboratory mice; a felt layer 3 fixedly disposed on the upper surface of the restraint net 2 to provide a point of leverage for the laboratory mice's paws; and an end cap 4 for fitting onto the end of the net tube, and the end cap 4 has a perforation 5 in the middle for the laboratory mice's tail to pass through.

[0020] The binding net 2 has a width of 10cm-15cm, a length of 8cm-15cm, and a thickness of 1mm-3mm. The diameter of the mesh openings in the binding net 2 is 3mm-5mm. The felt layer 3 can be made of suede or cloth.

[0021] Holding the mouse by the tail, place it on the restraint net 2 and drag the tail backward. Due to its natural instincts, the mouse's paws will grip the felt layer 3. At this point, wrap the mouse around the restraint net 2 from one side at least once, so that the mouse is inside the net tube. The experimenter then injects the mouse through the mesh of the restraint net 2.

[0022] This anti-bite auxiliary mouse restraint device can quickly restrain laboratory mice and prevent them from scratching or biting laboratory personnel, ensuring the safety of laboratory personnel. It is especially suitable for operators who are restraining laboratory mice for the first time, and facilitates the restraint of laboratory mice without anesthesia, so as to carry out experiments such as intraperitoneal injection, anesthesia, and gavage.

[0023] In this embodiment, as Figure 1 and Figure 7 The binding net 2 has adhesive-backed soft magnetic strips 6 on both ends of its opposite surfaces to prevent the net cylinder from unraveling. The length of the adhesive-backed soft magnetic strips 6 surrounds the circumference of the net cylinder.

[0024] The adhesive-backed soft magnetic strip 6 has a length of 8cm-15cm, a width of 0.8cm-3cm, and a thickness of 2mm. When the binding net 2 is rolled up, the adhesive-backed soft magnetic strip 6 wraps around the net once. The overlapping parts of the adhesive-backed soft magnetic strip 6 attract each other, which can prevent the net from unraveling and prevent the experimental mice from escaping.

[0025] In this embodiment, as Figure 1-2 , Figure 6 and Figure 10 Limiting rings 7 are fixedly provided at both ends of the upper surface of the binding net 2, and the ring surface of the limiting rings 7 is parallel to the end face of the net cylinder.

[0026] The limiting ring 7 is used to limit the minimum diameter of the binding net 2 when it is rolled into a cylinder. The inner diameter of the limiting ring 7 is 2cm-3cm. It also prevents the ends of the cylinder from collapsing, thus keeping the cylinder in a cylindrical shape. In this embodiment, as Figure 1 The two limiting rings 7 are divided into a head limiting ring and a tail limiting ring. The head limiting ring is located on the side of the felt layer 3 away from the tail limiting ring. The tail limiting ring has a notch 8 to facilitate the passage of the experimental mouse's tail.

[0027] The experimental mouse is placed between the head restraint ring and the felt layer 3, and the tail of the experimental mouse is dragged toward the tail restraint ring. The tail of the experimental mouse is then inserted into the tail restraint ring through the notch 8.

[0028] In this embodiment, as Figure 5 and Figure 8 A plug body is slidably fitted inside the mesh cylinder, and a push rod 9 is fixedly connected to the end face of the plug body.

[0029] The inner diameter of the plug is 2cm-3cm. By pushing the push rod 9, the plug can pass through the limiting ring 7, which allows the plug to push the experimental mouse in the net tube and adjust the position of the experimental mouse in the net tube.

[0030] In this embodiment, as Figure 4 Both sides of the end cap 4 are provided with Velcro 12 for attaching the end cap 4 to the mesh cylinder.

[0031] To facilitate fixing the end cap 4 to the end of the mesh tube, the Velcro 12 can also be replaced with tape.

[0032] In this embodiment, as Figure 1-2 and Figure 9 On the opposite vertical surfaces of the placement platform 1, there are multiple protrusions 10 for supporting the binding net 2, and on the platform surface of the placement platform 1, there are also baffles 11 for blocking the binding net 2.

[0033] The protrusion 10 is used to support the restraint net 2 on the side, so that there is a gap between the hanging restraint net 2 and the side of the placement table 1, making it easy for the experimenter to pick up the edge of the restraint net 2. At the same time, the stop bar 11 is located on the edge of the table surface of the placement table 1, which is used to quickly position the restraint net 2 and also prevents the restraint net 2 from slipping off the placement table 1 during the dragging of the experimental mouse.

[0034] The method of using the anti-bite auxiliary mouse restraint device of this utility model is as follows: First, lay the restraint net 2 flat on the surface of the placement platform 1; Then, the experimenters lifted the mouse by the tail, placed the mouse between the head restraint ring and the felt layer 3, and dragged the mouse's tail toward the tail restraint ring, and inserted the mouse's tail through the notch 8 into the tail restraint ring. Next, roll up the restraint net 2 so that the experimental mouse is inside the net tube, and pass the experimental mouse's tail through the perforation 5. Use Velcro 12 to attach the end cap 4 to the roll tube. Finally, the plug is placed into the mesh tube through the head restraint ring, the position of the experimental mouse in the mesh tube is adjusted, and the experimental mouse is tested, such as by intraperitoneal injection or intravenous injection.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
