Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory mouse artery clip technology, specifically an artery clip for laboratory mice used in apoptosis research. Background Technology
[0002] In experimental studies of apoptosis, mice are required. During these studies, blood needs to be drawn or the mice dissected. Arterial clamps are used to stop the bleeding. Existing arterial clamps often have a fixed opening mechanism, resulting in a small clamping portion and a large opening portion, which is structurally unoptimized. Furthermore, due to their large size and numerous rings and protrusions, the clamps are prone to detachment during rat struggles, hindering the experiment. Therefore, we propose an arterial clamp for mice used in apoptosis research to address these issues. Utility Model Content
[0003] The purpose of this invention is to provide an arterial clamp for laboratory mice used in apoptosis research, in order to solve the problems mentioned in the background art, such as the lack of optimization of the existing arterial clamp mechanism and the presence of many rings and protrusions, which make the arterial clamp prone to detachment during rat struggle.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an arterial clamp for laboratory mice used in apoptosis research, comprising a U-shaped clamping ring.
[0005] A clamping block is provided on the U-shaped clamping ring, and the clamping block is located at the end of the U-shaped clamping ring;
[0006] The opening mechanism is movably disposed on one side of the U-shaped clamping ring and is used to open the U-shaped clamping ring.

The upper clamping block is provided with an array of anti-slip grooves, and the lower clamping block is provided with an array of anti-slip blocks. The anti-slip grooves and anti-slip blocks are positioned opposite each other.
[0009] Preferably, the opening mechanism includes an opening ring, which is disposed on the upper and lower sides of the U-shaped clamping ring. A first rotating rod and a second rotating rod are disposed on one side of the U-shaped clamping ring. The first rotating rod and the second rotating rod are hinged to each other and each end is fixedly installed with an insertion block. The insertion block is inserted into the opening ring.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 One embodiment of this utility model is an arterial clamp for laboratory mice used in apoptosis research, comprising a U-shaped clamping ring 1.
[0022] A clamping block 2 is provided on the U-shaped clamping ring 1, and the clamping block 2 is located at the end of the U-shaped clamping ring 1;
[0023] The opening mechanism is movably set on one side of the U-shaped clamping ring 1 and is used to open the U-shaped clamping ring 1.
[0024] The locking mechanism is installed on the opening mechanism. The locking mechanism is used to lock the opening mechanism onto the opening mechanism. The separate opening mechanism makes the structure of the equipment more optimized, smaller in size, and simpler in structure, which increases the stability of the equipment during use. The opening mechanism can also rebound to make the opening mechanism easier to use.
[0025] Furthermore, there are two sets of clamping blocks 2, respectively located on the upper and lower sides of the end of the U-shaped clamping ring 1. The upper clamping block 2 has an array of anti-slip grooves 3, and the lower clamping block 2 has an array of anti-slip blocks 4. The anti-slip grooves 3 and the anti-slip blocks 4 are positioned opposite each other. Figure 2 As shown, this structure makes the U-shaped clamping ring 1 simple and provides stable clamping, increasing the stability of the equipment during use.
[0026] Furthermore, the opening mechanism includes an opening ring 5, which is disposed on the upper and lower sides of the U-shaped clamping ring 1. A first rotating rod 6 and a second rotating rod 7 are disposed on one side of the U-shaped clamping ring 1. The first rotating rod 6 and the second rotating rod 7 are hinged together, and each end is fixedly fitted with an insertion block 8. The insertion block 8 is inserted into the opening ring 5, such as... Figure 1 As shown, this structure allows the opening mechanism to completely detach from the U-shaped clamping ring 1, optimizing the structure of the device and making the clamping of the device more stable and less likely to be detached.
[0027] Furthermore, the engaging mechanism includes an insertion block 8, the thickness of which is less than the height inside the opening ring 5. A limiting block 9 is fixedly installed at one end of the insertion block 8, the height of which is less than the height inside the opening ring 5. The right edge of the opening ring 5 is arc-shaped. Figure 2 and Figure 3 As shown, this structure allows the opening mechanism to open the U-shaped clamping ring 1 conveniently and stably, increasing the stability of the equipment during use.
[0028] Furthermore, anti-slip pads 10 are provided on both the upper and lower sides of the insertion block 8, and flexible pads 11 are provided at the ends of the second rotating rod 7 and the first rotating rod 6, such as... Figure 3 As shown, this structure makes the locking mechanism more stable and also makes the use of the first rotating rod 6 and the second rotating rod 7 more comfortable.
[0029] Furthermore, both the first rotating rod 6 and the second rotating rod 7 are provided with mounting blocks 12. A rotating shaft 13 is fixedly mounted on the mounting block 12 on the first rotating rod 6. A rotating groove 14 is formed on the mounting block 12 on the second rotating rod 7. The rotating shaft 13 is rotatably mounted within the rotating groove 14, and a torsion spring 15 is sleeved on the rotating shaft 13. Figure 4 As shown, this structure allows the first rotating rod 6 and the second rotating rod 7 to spring back without manual return, reducing the need for a circular handle and increasing the adaptability of the equipment during use.
[0030] Working principle: When in use, insert the insertion block 8 into the opening ring 5, then place your finger on the flexible pad 11 and press the ends of the first rotating rod 6 and the second rotating rod 7. At this time, the first rotating rod 6 and the second rotating rod 7 rotate relative to each other, causing the insertion block 8 to press against the opening ring 5. At this time, the limiting block 9 locks the edge of the opening ring 5, and the U-shaped clamping ring 1 is opened. Then, place the part to be clamped between the clamping blocks 2 and release the first rotating rod 6 and the second rotating rod 7. At this time, the torsion spring 15 rebounds, and then the insertion block 8 can be pulled out of the opening ring 5. The same principle applies to disassembling the U-shaped clamping ring 1. The above is the complete working principle of this utility model.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
