AI Technical Summary
In existing techniques, injection into the common carotid artery of mice is difficult because the blood vessel wall is thin and easily punctured, and the blood flow is fast, making it easy for blood to seep out at the injection site.
Design a vascular pad for common carotid artery injection, including a pad body and a handle. The pad body has a V-shaped groove for fixing the blood vessel and supporting the injection needle, and the handle is used to adjust the angle.
The procedure for injecting into the common carotid artery of mice is simple and reliable, avoiding vascular puncture and bleeding.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field, concretely is a blood vessel gasket for carotid artery injection. BACKGROUND
[0002] At present, when the carotid artery of experimental mouse is injected, generally, the carotid artery is injected manually after stripping, but because the carotid artery of experimental mouse is located at the deep muscle concave of neck, the blood vessel is thin, the blood vessel wall is thin, is easily punctured, the blood flow velocity is fast, and the needle eye is easy to bleed, which leads to the difficulty of carotid artery injection of mouse. CONTENT OF THE UTILITY MODEL
[0003] The utility model discloses a blood vessel gasket for carotid artery injection, which makes the operation of carotid artery injection of mouse simple and reliable.
[0004] In order to achieve the above-mentioned purpose, the utility model discloses the following technical scheme:
[0005] A blood vessel gasket for carotid artery injection, comprising a gasket body, a handle is arranged at the rear end of the gasket body, a plurality of V-shaped grooves are arranged in sequence from front to back at the top of the gasket body, and the length of the V-shaped groove is the same as the length of the gasket body.
[0006] Preferably, a round corner is arranged between the two adjacent V-shaped grooves and at the bottom of the V-shaped groove.
[0007] Preferably, an anti-skid line is arranged on the handle.
[0008] Preferably, the gasket body comprises a front rectangular plate and a rear trapezoidal plate.
[0009] Compared with the prior art, the utility model has the beneficial effects that:
[0010] The V-shaped groove of the utility model can fix the blood vessel of mouse and support the injection needle, the two end edges of the V-shaped groove can block the blood flow at the front and rear ends of the needle eye, the handle can be adjusted at any angle during the whole process, which is convenient to operate and can solve the problem of difficulty in carotid artery injection of mouse in the prior art, and the operation of carotid artery injection of mouse becomes simple and reliable. DRAWING DESCRIPTION
[0011] Fig. 1 It is the three-dimensional structure schematic diagram of the utility model;
[0012] Fig. 2 It is the plan view of the utility model.
[0013] Reference numerals in the drawing: 1, gasket body; 2, handle; 3, V-shaped groove. DETAILED DESCRIPTION
[0014] The utility model is further explained below in combination with specific embodiments. It should be understood that these embodiments are only used for illustrating the utility model and are not used for limiting the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms are also within the scope defined by the present application.
[0015] Embodiment: as attached Figs. 1-2 The utility model discloses a carotid artery injection blood vessel gasket can adopt the plastic material, including gasket body 1, gasket body 1's rear end is equipped with handle 2, gasket body 1 with handle 2 can adopt integral structure, integral forming, gasket body 1 is board -shaped, gasket body 1's top is equipped with a plurality of V -groove 3 from front to back in proper order, and V -groove 3's length is same with gasket body 1's length, V -groove 3 is arranged two at least.
[0016] Preferably, the adjacent two V-grooves 3 and the bottom of the V-groove 3 are provided with a fillet.
[0017] Preferably, the handle 2 is provided with anti-skid lines.
[0018] Preferably, the gasket body 1 includes a front rectangular plate and a rear trapezoidal plate, the front rectangular plate and the rear trapezoidal plate are integrally formed, the long side of the rear trapezoidal plate is the same as the length of the front rectangular plate, the short side of the rear trapezoidal plate is the same as the width of the handle 2, the lengths of the V-grooves 3 on the front rectangular plate are the same, and the lengths of the V-grooves 3 on the rear trapezoidal plate gradually decrease from front to back, which can be suitable for different use requirements.
[0019] The V-grooves 3 on the gasket body 1 can fix the blood vessels and support the injection needle. When the carotid artery of the mouse is injected, the carotid artery of the mouse is placed in one of the V-grooves 3, the needle tip enters the blood vessel along the V-groove 3, and the blood vessel is prevented from being pierced due to hand shaking. The gasket body 1 is lifted, the carotid artery is bent at the gasket body 1, the edges at both ends of the V-groove 3 can block the blood flow at the front and rear ends of the needle hole, and bleeding at the needle hole is temporarily avoided. The handle 2 can adjust the angle of the gasket body 1 during the carotid artery injection, which is convenient to operate.
