Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection restraint technology, and in particular to a small animal intravenous injection restraint device. Background Technology
[0002] Small animal intravenous injection restraint refers to maintaining the animal in a stable state during intravenous injection through physical fixation or drug sedation to ensure the safety and accuracy of the injection operation. Different animals require different restraint methods based on their size and habits. For example, small animals are often restrained by fixing their body and tail.
[0003] Currently, some experimental small animals are restrained by compression plates during intravenous injection. However, when the animal's limbs are extended, the compression plate presses directly on them, causing crush injuries to the limbs during injection due to the pressure exerted by the plate. To address this issue, we propose a restraint device for intravenous injection in small animals. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where, during intravenous injection of small experimental animals, some animals are restrained by a clamping plate. However, when the animal's limbs are extended, the clamping plate presses directly onto the limbs, causing pressure injuries to the limbs during injection due to the clamping plate's compressive force. Therefore, this invention proposes a restraint device for intravenous injection of small animals.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A restraint device for intravenous injection in small animals includes a locking plate, a squeezing base plate fixedly connected to the lower end of the locking plate, a through groove on the upper end face of the locking plate, an installation mechanism installed above the squeezing base plate, and a buffer mechanism connected inside the installation mechanism.
[0006] Preferably, the installation mechanism includes mounting bolts, and an installation plate is mounted on the top of the extrusion base plate via the mounting bolts, with fixing frames fixedly connected to both ends of the installation plate.
[0007] Preferably, the cross-section of the mounting plate is arc-shaped, and multiple mounting bolts are installed at equal intervals within the mounting plate.
[0008] Preferably, the buffer mechanism includes a buffer spring, the inner wall of the fixed frame is welded to one end of the buffer spring, and the other end of the buffer spring is welded to the top of the connecting plate. A pressure plate is fixedly connected to the bottom of the connecting plate by a connecting column.
[0009] Preferably, a cushioning pad is glued to the underside of the pressing plate, and the pressing plate and the cushioning pad have the same surface dimensions.
[0010] Preferably, the surface dimensions of the connecting plate are adapted to the inner wall dimensions of the fixed frame, and multiple buffer springs are provided between the connecting plate and the fixed frame.
[0011] Preferably, the connecting column is cylindrical, and the extrusion base plate has grooves on both sides that are adapted to the connecting column.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device allows for the convenient subcutaneous intravenous injection of small animals by placing them into the clamping plate and pulling out the upper skin of the small animals through the through groove. At the same time, when the clamping plate is engaged, the clamping plate can drive the buffer pad to press against the limbs of the small animals. The elasticity of the buffer spring itself can play a buffering and protective role, avoiding direct hard pressure from the squeezing base plate, which could cause damage to the limbs.
[0013] 2. The device moves along the surface of the fixed frame via the connecting plate, which can limit and guide the connecting column and the pressing plate. At the same time, the mounting bolts pass through the mounting plate and are threaded to the extrusion base plate, which can facilitate the assembly and disassembly of the mounting plate and the fixed frame. The grooves on both sides of the extrusion base plate can facilitate the engagement and connection of the connecting column. Attached Figure Description

[0016] 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.
[0017] Reference Figure 1-4 A small animal intravenous injection restraint device includes a locking plate 1, a compression base plate 2 fixedly connected to the lower end of the locking plate 1, a through groove 3 opened on the upper end surface of the locking plate 1, an installation mechanism 4 installed above the compression base plate 2, and a buffer mechanism 5 connected inside the installation mechanism 4, so that the function of the buffer mechanism 5 can be conveniently installed through the installation mechanism 4.
[0018] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the installation mechanism 4 includes installation bolts 41. An installation plate 42 is installed on the top of the extrusion base plate 2 by the installation bolts 41, and a fixing frame 43 is fixedly connected to both ends of the installation plate 42. The installation bolts 41 pass through the installation plate 42 and are threadedly connected to the extrusion base plate 2, which makes it easy to disassemble and assemble the fixing frame 43.
[0019] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the cross-section of the mounting plate 42 is set to be arc-shaped, and multiple mounting bolts 41 are installed at equal intervals within the mounting plate 42. The arc-shaped cross-section of the mounting plate 42 facilitates its installation above the extrusion base plate 2, and the multiple mounting bolts 41 increase the installation stability of the mounting plate 42.
[0020] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the buffer mechanism 5 includes a buffer spring 51. The inner wall of the fixed frame 43 is welded to one end of the buffer spring 51, and the other end of the buffer spring 51 is welded to the top of the connecting plate 52. The buffer spring 51 can play a buffering role through its own elasticity. The connecting plate 52 is fixedly connected to the bottom of the connecting plate 52 by the connecting column 53. The connecting column 53 drives the pressing plate 54 to press onto the limbs, which can play a buffering and protection role.
[0021] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a buffer pad 55 is glued to the bottom of the pressing plate 54. The surface dimensions of the pressing plate 54 and the buffer pad 55 are the same. The buffer pad 55 glued to the bottom of the pressing plate 54 can play a protective role.
[0022] Furthermore, refer to Figure 3 and Figure 4It can be seen that the surface dimensions of the connecting plate 52 are adapted to the inner wall dimensions of the fixed frame 43. The connecting plate 52 can conveniently limit and guide the function of the connecting plate 52 and the connecting column 53. Multiple buffer springs 51 are provided between the connecting plate 52 and the fixed frame 43. The multiple buffer springs 51 can increase the buffering force.
[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the connecting post 53 is cylindrical, and the extrusion base plate 2 has grooves on both sides that are adapted to the connecting post 53. By extruding the grooves on both sides of the base plate 2, the connecting post 53 can be inserted into the grooves.
[0024] Working principle: When this utility model is in use, the locking plate 1, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 By threading the mounting bolt 41 through the mounting plate 42 and connecting it to the extrusion base plate 2, the fixing frame 43 can be easily installed on the top of the extrusion base plate 2. At the same time, the connecting column 53 can be engaged in the groove opened on the side of the extrusion base plate 2. When the small animal is engaged in the engaging pressure plate 1, the pressure plate 54 can drive the buffer pad 55 to press against the limbs of the small animal. The elasticity of the multiple buffer springs 51 and the buffer pad 55 can play a buffering and protective role. At this time, the skin of the small animal can be pulled out through the through groove 3, which is convenient for subcutaneous intravenous injection. The above is the complete working principle of this utility model.
