Problems solved by technology

At present, in animal experiments, ordinary needles or scalp needles are used for ear vein injection, which can only meet one administration. Conventional adhesive tape is used to fix it, and it will not stick when there is a little water. The fixation effect is not good, and the ear vein will soon become unobstructed, or the needle will be pulled out due to poor fixation. Sometimes it is difficult to carry out the experiment smoothly, especially in the When students experiment

Embodiment Construction

[0010] As shown in the accompanying drawings, the multifunctional needle of the present invention mainly includes an infusion tube 3, a three-way regulating valve 4 and a needle tube 5. One end of the infusion tube 3 has a needle 1, and a fixing clip 2 is arranged on the needle 1. A three-way regulating valve 4 is installed in the infusion tube 3, and the three channels of the three-way regulating valve 4 are respectively connected with the front section of the infusion tube 3, the rear section of the infusion tube 3 and the needle tube 5, and the front section of the infusion tube 3 is provided with a needle 1 . The fixing clip 2 can be used with a handle when injecting, and can be clamped on the animal's ear to play the role of fixing the needle.

[0011] When it is necessary to infuse the animal, adjust the three-way regulating valve 4 so that the two passages connected to the front section and the rear section of the infusion tube 3 in the three-way regulating valve 4 comm...

Abstract

The invention provides a multifunctional needle for experimental animal ear margin intravenous injection dosing transfusion and fixing. The needle comprises a transfusion pipe, a three-way adjusting valve and a needle tube. One end of the transfusion pipe is provided with a syringe, a fixing clip is arranged on the syringe, the three-way adjusting valve is installed in the transfusion pipe, and three channels of the three-way adjusting valve are connected with the front section and the rear section of the transfusion pipe and the needle tube respectively. The multifunctional needle can achieve ear margin intravenous injection dosing, anesthesia, transfusion and fixing of experimental animals, achieves firm fixing, can conduct injection dosing, anesthesia and transfusion simultaneously without pulling and inserting the syringe for multiple times, enables an experiment to go on wheels and ensures experiment effects.

Description

technical field [0001] The invention relates to an injection needle used for intravenous administration and transfusion to the ear edge of experimental animals, and belongs to the technical field of injection needles. Background technique [0002] In the teaching and scientific research of biological science and medicine, it is often necessary to use animals to replicate various disease models and perform experimental operations. Many experiments require simultaneous injection, anesthesia, and infusion from the ear veins of animals. operate. At present, in animal experiments, ordinary needles or scalp needles are used for ear vein injection, which can only meet one administration. Conventional adhesive tape is used to fix it, and it will not stick when there is a little water. The fixation effect is not good, and the ear vein will soon become unobstructed, or the needle will be pulled out due to poor fixation. Sometimes it is difficult to carry out the experiment smoothly, ...
