[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-3 As shown, a conveniently fixed pet indwelling needle comprises

[0021] A pet indwelling needle tube body 1 and a flip sheet 4 are arranged at the side position of the pet indwelling needle tube body 1; a plug-in connection hole 5 is arranged on the flip sheet 4; a left silicone sheet 7 and a right silicone sheet 10 are arranged at the side position of the flip sheet 4, and a plug-in fixing buckle 9 is arranged at the side position connecting the left silicone sheet 7 and the right silicone sheet 10, and an inserting inner cylinder 14 is arranged at the middle position of the inserting fixing buckle 9, and a pressing ring 11 is arranged at the outer position of the inserting inner cylinder 14, and a snap-in connecting column 13 is arranged inside the pressing ring 11. The end of the snap-in connecting column 13 is a slope structure. Pressing the pressing ring 11 will cause the inserting inner cylinder 14 to squeeze the snap-in connecting column 13 to move outward, and the extended snap-in connecting column 13 will snap and prevent the plug-in fixing buckle 9 from moving downward, thereby facilitating restricted fixation, thereby effectively improving the practicality of the pet indwelling needle.

[0022] like Figure 3 As shown, a limiting column groove 15 is provided at the side position of the snap-fit ​​connecting column 13, and the snap-fit ​​connecting column 13 is limited in movement on the pressing ring 11 by the limiting column groove 15. The setting of the limiting column groove 15 can effectively prevent the snap-fit ​​connecting column 13 from detaching from the pressing ring 11 and falling off and being lost.

[0023] like Figure 3As shown, a limiting column groove 16 is provided at the side position of the plug-in inner cylinder 14. The limiting column groove 16 can limit the relative movement distance of the plug-in inner cylinder 14 and the pressing ring 11. The setting of the limiting column groove 16 can limit the movement distance of the pressing ring 11 in the plug-in inner cylinder 14 to prevent it from detaching from the plug-in inner cylinder 14.

[0024] like Figure 1 As shown, an elastic band groove layer 8 is provided at the position between the left silicone sheet 7 and the right silicone sheet 10. The elastic band groove layer 8 is made of materials such as rubber, polyester, glue, and elastic fiber. The left silicone sheet 7 and the right silicone sheet 10 are elastically connected through the elastic band groove layer 8. The composition of the elastic band groove layer 8 makes it have a certain degree of elasticity, so that it can be adjusted according to the thickness of different pets, thereby improving its adaptability.

[0025] like Figure 1 As shown, a pet indwelling needle needle 2 is arranged at the upper end of the pet indwelling needle tube body 1. The pet indwelling needle needle 2 is made of stainless steel, and the top of the pet indwelling needle needle 2 is a sloped tip structure. The sloped tip of the pet indwelling needle needle 2 can reduce the force area of ​​the pet indwelling needle and increase the pressure, so that it is easier to pierce the pet's fur and enter the vein.

[0026] like Figure 1 As shown, a retention needle textured tube 3 is provided near the bottom of the pet retention needle tube body 1. The retention needle textured tube 3 is composed of multiple layers of rings with an outer diameter larger than the pet retention needle tube body 1. The retention needle textured tube 3 can increase the friction between the user's hand, thereby making it more convenient for the user to perform the needle operation.

[0027] like Figure 1 As shown, a heparin cap 6 is provided at the bottom of the indwelling needle pattern tube 3. The heparin cap 6 is installed and connected to the pet indwelling needle tube body 1 by plugging. The heparin cap 6 is a matching connector device containing heparin components, which is mostly used for intravenous indwelling needles, central venous catheterization and other operations. It can effectively reduce repeated skin punctures, prolong the use time of intravenous indwelling needles, reduce patients' medical expenses, and improve clinical work efficiency.

[0028] During operation, the pet indwelling needle needle 2 is inserted into the pet's body vein, and then fixedly buckled by connecting the left silicone sheet 7, the right silicone sheet 10 and the plug-in fixing buckle 9. When the infusion is completed, the needle tube is pulled out from the end of the pet indwelling needle tube body 1, and then the indwelling needle heparin cap 6 is inserted. When infusion is needed later, the indwelling needle heparin cap 6 can be replaced with an infusion tube.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
