The rat tail intravenous injection technology is a common administration mode in animal experiments, and the technology needs long-term training to be mastered, and often brings trouble to researchers just related to the technology. When the medicine is pushed out of the tail vein of the mouse, the traditional injector in the prior art is often used for shaking hands, so that the needle is removed from the tail vein of the mouse, and the injection fails.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model provides a novel anti-shake syringe.

In order to achieve the above object, the utility model adopts the following technical scheme:

a novel anti-shake tail vein injector comprises a needle cylinder, a needle head connected with the top of the needle cylinder, a push button positioned on the outer side of the needle cylinder and a piston positioned on the inner side of the needle cylinder; the push button and the piston are connected to each other.

The utility model discloses following beneficial effect has: the use is located the syringe outside and pushes away the button and control the inside piston of syringe and inhale or push out liquid, and unique design makes the user can utilize whole palm to hold the syringe when the injection, greatly increased stability, has avoided shaking the injection failure condition that leads to the syringe needle to remove mouse tail vein because of the hand.

Preferably, the outer surface of the push button is in a insection shape.

This preferred solution has the following beneficial effects: the outer surface of the push button is designed into a insection shape to play a role in skid resistance, so that the problem that the injection of a user fails due to the fact that the push button is too slippery in the process of rat tail intravenous injection can be prevented.

Preferably, the piston is made of rubber materials and is tightly attached to the inner wall of the needle cylinder.

This preferred solution has the following beneficial effects: the close fit of the piston and the inner wall of the syringe ensures that a user can effectively suck liquid into the syringe or push the liquid out of the syringe to enter the rat tail vein in the injection process, and the high elasticity of the rubber material ensures that the piston can still freely move along the inner wall of the syringe while being tightly fitted with the inner wall of the syringe.

Preferably, the push button and the piston are connected to each other by a U-shaped connecting rod, one end of which is located outside the cylinder and connected to the push button, and the other end of which extends from the bottom of the cylinder into the interior of the cylinder and is connected to the piston.

This preferred solution has the following beneficial effects: the push button positioned on the outer side of the needle cylinder is connected with the piston positioned on the inner side of the needle cylinder in a U-shaped connecting rod mode, the structure is simple, the realization is easy, and the production and the processing are convenient.

Preferably, the syringe surface is marked with an internal liquid volume scale.

This preferred solution has the following beneficial effects: the volume scales are arranged on the surface of the syringe, so that the dosage of the injection liquid is more accurate when a user carries out the tail vein injection process.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1, the utility model provides a novel anti-shake tail vein injector, which comprises a syringe 4, a needle head 1 connected with the top of the syringe 4, a push button 2 positioned at the outer side of the syringe 4 and a piston 5 positioned at the inner side of the syringe 4; the push button 2 and the piston 5 are connected to each other.

The utility model designs a unique use is located the structure that inside piston 4 was controlled to push away button 2 in the 4 outsides of syringe cylinder, and this kind of structure can make the user can use whole palm to grip cylinder 4 when carrying out the injection operation, has increased the stability when injecting.

In the embodiment of the utility model, the outer surface of the push button 2 is in the shape of insection.

The insection design may increase the friction between the surface of the push button 2 and the user's thumb, preventing the user from slipping off the surface of the push button 2 during pushing with the thumb, which may result in an injection failure.

In the embodiment of the utility model, the piston 5 is made of rubber material and closely attached to the inner wall of the needle cylinder 4.

In the embodiment of the utility model, push button 2 and piston 5 interconnect through U type connecting rod 3, and connecting rod 3 one end is located cylinder 4 outside and is connected with push button 2, and the other end stretches into inside cylinder 4 and be connected with piston 5 from cylinder 4 bottom.

In the embodiment, the push button 2 and the piston 5 are connected by adopting the mode of the U-shaped connecting rod 3, the push button 2 and the piston 5 can be connected by adopting the design under the condition of not changing the structure of the traditional syringe, and the structure is simple and easy to produce.

In the embodiment of the utility model, the surface of the needle cylinder 4 is marked with the internal liquid volume scale.

In actual medical experiments, the dosage of the injection liquid injected into the tail vein of the mouse by a user is always strictly regulated, and the liquid volume scale is arranged on the surface of the syringe 4 so that the user can conveniently control the dosage of the injection liquid.

Referring to fig. 2, the specific usage of the embodiment of the present invention is to hold the syringe 4 with the right hand, put the thumb on the push button 2, and push the push button 2 to slide up and down on the outer wall of the syringe 4 to control the piston 5 to move up and down inside the syringe 4, so as to achieve the purpose of sucking or pushing out the liquid.

To sum up, the utility model provides a tail vein injection ware that can use whole palm to grip at tail vein injection in-process has promoted the stability of tail vein injection process, has effectively avoided taking place because of the injection failure condition that the hand trembled and lead to.

It will be appreciated by those of ordinary skill in the art that the embodiments described herein are intended to assist the reader in understanding the principles of the invention, and it is to be understood that the scope of the invention is not limited to such specific statements and embodiments.
