Description

Technical Field

[0001] The utility model relates to the technical field of mouse tail vein injection, in particular to a mouse tail vein syringe. Background Art

[0002] When conducting medical experiments, such as syringe use practice, white mice are commonly used as experimental materials. There are 2 arteries and 3 veins in the tail of a mouse, which is a suitable injection site. The current method is to fix the mouse using a fixing device such as a cage or a mouse trap, pull out the tail through the hole of the cage or mouse trap, hold the mouse tail by hand, and then perform the injection. There are 2 arteries and 3 veins in the tail of a mouse, and a suitable vein can be selected for injection. Before injection, the hair along the tail vein needs to be plucked, and after disinfection, the injection is carried out.

[0003] In the use process of the existing mouse tail vein syringe, only the fixing sleeve is used to clamp and fix the body of the mouse, while the tail of the mouse needs to be manually straightened and then pressed to prevent it from shaking. However, during the manual fixing process, since the mouse tail is relatively thin, it is not convenient to apply an external force to it, resulting in the tail being easily detached from the hand. This not only causes inconvenience to the staff but also leads to poor use effect of the device. Therefore, there is an urgent need for a mouse tail vein syringe to solve the above problems.

[0013] The beneficial technical effects of the present utility model:

[0014] The present utility model designs a carding assembly composed of a guiding groove, a guiding block, a carding block, a pressing plate, a pressing rod, a bearing seat, a roller and a spring. During the carding process of the mouse's tail, the tail is passed through the carding groove, and then an external force is applied to the pressing plate, so that the roller is driven by the pressing plate to move downward to press the tail. At the same time, under the action of the guiding block and the guiding groove, the carding block is pushed to move along the injection plate, so that the tail can be carded while being pressed, straightened, and continuously pressed after carding. This method is convenient for the staff to apply external force, thereby improving the pressing effect on the tail, ensuring the smooth progress of injection, and improving the use effect of the device.

[0021] To make the technical solutions of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation modes of the present utility model are not limited thereto.

[0022] As Figures 1-4 shown, a mouse tail vein syringe provided in this embodiment includes a base 1. A slantingly arranged bearing plate 2 is fixed to the upper end of the base 1. A fixed sleeve 3 is arranged at the upper end of the bearing plate 2. The bottom end of the fixed sleeve 3 is connected to an injection plate 5. A combing assembly 6 is arranged on the injection plate 5. The combing assembly 6 is composed of a guide groove 601, a guide block 602, a combing block 603, a combing groove 604 in an eight-shaped structure, a bearing seat 605 in a U-shaped structure, a roller 606, a pressure rod 607, a pressure plate 608, a guide rod 609 in a T-shaped structure, and a spring 610.

[0023] The bearing plate 2 is welded to the upper end of the base 1. The fixed sleeve 3 is welded to the bearing plate 2. A through cavity is formed in the middle of the bottom end of the fixed sleeve 3. The fixed sleeve 3 can provide a placement space for the mouse.

[0024] Two groups of locking screws 4 are symmetrically installed on both side walls of the fixed sleeve 3 through threads. An arc-shaped locking plate 7 is rotatably installed at one end of the locking screw 4. By rotating the locking screw 4 to push the locking plate 7 to move under the action of the thread, the body of the mouse can be locked and fixed.

[0025] The injection plate 5 is welded to the bottom wall of the fixed sleeve 3. The guide groove 601 is formed on the injection plate 5. The guide block 602 is slidably connected to the guide groove 601. The tail of the mouse is on the injection plate 5 through the through cavity at the bottom end of the fixed sleeve 3. The combination of the guide block 602 and the guide groove 601 can make the combing block 603 slide.

[0026] The combing block 603 is connected to the guide block 602 through a bracket. The combing groove 604 is formed on the combing block 603. The combing block 603 is slidably connected to the injection plate 5. The tail of the mouse is passed through the combing groove 604. The tail of the mouse can be combed during the movement of the combing block 603.

[0027] The roller 606 is rotatably installed in the bearing seat 605. The pressing rod 607 penetrates through the carding block 603 and is connected to the top end of the bearing seat 605 by screws. The pressing plate 608 is welded to the top end of the pressing plate 608. During the carding process, the pressing plate 608 drives the pressing rod 607 and the roller 606 to move downward to press and fix the tail of the mouse.

[0028] The guide rod 609 is welded to the carding block 603. The pressing plate 608 is slidably connected to the guide rod 609. The spring 610 is welded between the pressing plate 608 and the carding block 603. The spring 610 wraps the guide rod 609. The guide rod 609 guides the movement of the pressing plate 608. The spring 610 can automatically reset the pressing plate 608 after the external force is released.

[0029] The working principle of this device: First, place the mouse in the fixing sleeve 3 and make its tail pass through the through cavity and the carding groove 604 on the carding block 603. Then rotate the locking bolt, and under the action of the thread, drive the locking plate 7 to move to lock and fix the body of the mouse. Then card the tail of the mouse. During the carding process, apply an external force to the pressing plate 608, so that it drives the roller 606 to move downward to press the tail through the pressing plate 608. At the same time, under the action of the guide block 602 and the guide groove 601, push the carding block 603 to move along the injection plate 5, so that the tail can be carded while being pressed, straightened, and continuously pressed after carding. This method is convenient for the staff to apply external force, thereby improving the pressing effect on the tail and ensuring the smooth progress of the injection. After the injection is completed, release the external force, and the pressing plate 608 resets under the action of the spring 610.
