Description

Technical Field

[0001] This utility model relates to the field of animal medical technology, specifically to a vascular injection device for animal medical experiments. Background Technology

[0002] Animal medicine mainly involves disciplines such as basic veterinary medicine, preventive veterinary medicine, clinical veterinary medicine, veterinary pharmacy, and veterinary hygiene. It requires basic theories, knowledge, and skills in small animal disease prevention and control, ranch medicine, veterinary public health, and veterinary medicine. In the process of animal medicine experiments, intravenous injection is required.

[0003] Existing technologies, such as CN211485077U, describe a vascular injection device for animal medical experiments. This invention features an outer cylinder that is movable outside the inner cylinder. When the capacity of the inner cylinder is insufficient, the outer cylinder can be pulled out from the outside of the inner cylinder to increase the overall capacity of the injection device, making it more flexible and widely applicable.

[0004] However, this device still has some shortcomings in its use:

[0005] 1. When using this device for intravenous injection, the push tube and piston must be pushed with the help of the fixing sleeve in order to discharge the drug solution in the inner cylinder. However, this process is somewhat inconvenient. When the operator operates with only one hand, it is easy to slip or have stability problems, which reduces the convenience of operation.

[0006] 2. Due to the combination of the inner and outer tubes, it is difficult for staff to accurately determine the amount of medication in the syringe, and the connection between the needle and the inner tube is exposed to the external environment, which reduces the safety of use. Utility Model Content

[0007] The purpose of this invention is to provide a vascular injection device for animal medical experiments, to solve the problem mentioned in the background art that when using this device for vascular injection, a fixed sleeve must be used to push the push tube and piston to discharge the drug solution in the inner cylinder. However, this process is inconvenient. When the operator operates with only one hand, it is easy to slip or cause instability problems, which reduces the convenience of operation. With the combination of the inner and outer cylinders, it is difficult for the operator to control the specific amount of drug solution in the injection tube, and the connection between the needle and the inner cylinder is exposed to the external environment, which reduces the safety of use.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0012] As a preferred embodiment of this utility model, the end of the injection tube is fixedly connected to an installation head, and an injection needle is snapped into the installation head. The injection tube, the installation head, and the injection needle are connected to each other.

[0013] As a preferred embodiment of this utility model, both the fixed plate and the movable plate are made of stainless steel, and anti-slip grooves are provided on the outer surfaces of both the fixed plate and the movable plate.

[0014] As a preferred embodiment of this utility model, the end of the push plate is arc-shaped, and the material of the push plate is the same as that of the movable plate.

[0016] As a preferred embodiment of this utility model, two connecting plates are provided, and the two connecting plates are positioned opposite each other.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1.

[0028] Since the movable plate 2 and the fixed plate 1 are hinged together, and the movable plate 2 is also hinged to the push plate 3, the end of the push plate 3 abuts against the push groove 11, thereby improving convenience and stability.

[0029] According to this embodiment Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a connecting plate 13 is fixedly connected to the side of the injection tube 4. The connecting plate 13 extends into the snap-fit ​​hole 9 and snaps into the snap-fit ​​hole 9. An installation hole 14 is opened on the outer surface of the injection tube 4. A liquid level gauge 15 is fixedly connected in the installation hole 14. The outer surface of the liquid level gauge 15 is set with a value. An push head 12 is fixedly connected to the end of the push rod 5. The push head 12 abuts against the inner wall of the injection tube 4. The push head 12 is made of rubber. The push rod 5 is made of resin. The fixed plate 1 and the movable plate 2 are both made of stainless steel.

[0031] The working process of this utility model is as follows: When using the vascular injection device for animal medical experiments designed in this scheme, first check whether the device is working properly. Draw the required drug solution into the injection tube 4. When it is necessary to inject the animal, the operator only needs to squeeze the fixed plate 1 and the movable plate 2 with one hand to slide the push rod 5 and the push head 12, thereby discharging the drug solution in the injection tube 4 through the injection needle 7. Since the movable plate 2 and the fixed plate 1 are hinged, and the movable plate 2 is also hinged to the push plate 3, the end of the push plate 3 abuts against the push groove 11, thereby improving convenience and stability. At the same time, an anti-slip pad 10 is also provided in the mounting groove 8, thereby improving the stability of the injection tube 4. A liquid level gauge 15 is provided in the mounting hole 14, which makes it easy for the operator to know the amount of drug solution in the injection tube 4.
