Technical Field

[0001] The present invention relates to the technical field of education and training models, and specifically to a mouse tail vein injection model. Background Art

[0002] In medical teaching, it is necessary to perform tail vein injection on the tail of a mouse. Due to the impact of the epidemic, teaching is usually carried out online. Since it involves ethical live animals, it is difficult to appear in the live broadcast, which affects the teaching quality. Therefore, it is necessary to design a mouse model for online teaching.

[0003] There are four blood vessels on the mouse's tail, one on each of the upper, lower, left, and right sides. The one below is the artery, and the other three are veins. All three veins can be injected. However, in the current mouse model, there is only one venous blood vessel, which affects actual teaching and it is inconvenient to judge whether the syringe needle is inserted into the venous blood vessel. Therefore, we propose a mouse tail vein injection model to facilitate solving the problems raised above. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 ,the present invention provides a technical solution: a mouse tail vein injection model, comprising: a mouse model 1, a cavity 2, a drain hole 3, a sealing plug 4, an installation chamber 5, a water flow alarm 6, a swivel joint 7, a water inlet pipe 8, a sealing piece 9, a water outlet pipe 10, a connector 11, a guide piece 12, a groove 13, a drainage groove 14, and a blood vessel simulation tube 15.

[0023] The mouse model 1 has a cavity 2 opened in its abdomen, and a drain hole 3 is opened at the bottom of the front end of the cavity 2, and a sealing plug 4 is arranged inside the drain hole 3. An installation chamber 5 is opened above the rear side of the cavity 2, and a water flow alarm 6 is installed inside the installation chamber 5;

[0024] The water flow alarm 6 is arranged at the front end of the tail of the mouse model 1, and a water outlet pipe 10 is connected to the front end of the water flow alarm 6. A water inlet pipe 8 is connected to the rear end of the water flow alarm 6, and a sealing piece 9 is arranged at the connection between the water inlet pipe 8 and the water flow alarm 6. A connector 11 is connected to the rear end of the water inlet pipe 8, and a guide piece 12 is arranged outside the connector 11;

[0025] The groove 13 is opened on the outer side of the tail of the mouse model 1, and a drainage groove 14 is opened at the bottom of the groove 13. A blood vessel simulation tube 15 is arranged inside the groove 13, and the blood vessel simulation tube 15 is connected to the connector 11.

[0026] Such as Figure 1 、 Figure 3 and Figure 4 The inside of the cavity 2 is inclined, and the drain hole 3 is located at the bottommost end of the cavity 2, which is convenient for draining the water in the cavity 2. The sensor of the water flow alarm 6 is located inside the front end of the water outlet pipe 10, which is convenient for detecting the water flow. The water inlet pipe 8 is arranged on the left, right, top and bottom of the swivel joint 7, which is convenient for connecting multiple blood vessel simulation tubes 15 to the swivel joint �. The sealing piece 9 is of an elastic structure, and the sealing piece 9 seals the connection between the water inlet pipe 8 and the swivel joint 7, which is convenient for sealing the connection between the water inlet pipe 8 and the swivel joint 7.

[0027] Such as Figure 1 、 Figure 2 and Figure 4 The guide piece 12 is of an elastic structure, and the guide piece 12 is arranged in a conical structure, and the guide piece 12 and the connector 11 form a sliding structure, which is convenient for replacing the blood vessel simulation tube 15. The groove 13 is arranged on the left, right, top and bottom of the tail of the mouse model 1, and the drainage grooves 14 are equally spaced at the bottom of the groove 13, which is convenient for draining the water leaked from the blood vessel simulation tube 15.

[0028] Working principle: When using this mouse tail vein injection model, such as Figure 3As shown, first connect one end of the blood vessel simulation tube 15 to the guide piece 12. The guide piece 12 has a conical structure, which facilitates the installation of the blood vessel simulation tube 15 on the guide piece 12. By sliding the guide piece 12, the guide piece 12 moves on the connector 11. The guide piece 12 has an elastic structure, which facilitates the sliding of the guide piece 12 on the connector 11. As Figure 4 shown, during the sliding process of the guide piece 12, connect the blood vessel simulation tube 15 to the connector 11, and then install the blood vessel simulation tube 15 in the drainage groove 14;

[0029] During injection, as Figure 4 shown, insert the needle into the blood vessel simulation tube 15, and visually observe whether the blood vessel simulation tube 15 leaks liquid to determine whether the needle is inserted into the blood vessel simulation tube 15. When there is liquid leakage, the drainage groove 14 facilitates the discharge of the leaked liquid. When the needle is inserted into the blood vessel simulation tube 15, by squeezing the syringe, as Figure 1 shown, make the water flow into the adapter 7 through the water inlet pipe 8. The sealing piece 9 at the connection between the water inlet pipe 8 and the adapter 7 facilitates the one-way sealing of the port of the water inlet pipe 8, avoiding liquid leakage from other blood vessel simulation tubes 15 into the adapter 7 during injection. The liquid entering the adapter 7 is then discharged into the cavity 2 through the water outlet pipe 10 for storage. When there is liquid in the water outlet pipe 10, it is detected by the water flow alarm 6 and an alarm is sent to remind that the injection is completed. After use, by pulling out the sealing plug 4, it is convenient for the water in the cavity 2 to drain out through the drainage hole 3. This is the entire working process of the mouse tail vein injection model. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
