Description

Technical Field

[0001] The utility model relates to the field of life sciences, in particular to an integrated injection device. Background Art

[0002] In pharmacological and toxicological studies, in order to achieve precise control of the dosage, intravenous injection is a commonly used method of drug administration in animal experiments, and it is also an essential skill for getting started with scientific animal experiments. After intravenous injection, the drug can quickly enter the blood circulation and quickly exert its drug effect. Compared with traditional oral administration, intravenous injection can reduce the first-pass effect of drugs in the intestines and liver, allowing more drugs to reach the target tissues, while effectively avoiding the discomfort caused by taking the medicine. As a milder alternative method, animal tail vascular injection can weaken the animal's pain and stress response, and facilitate experimental applications of frequent or regular drug administration. As a routine technique, it helps to standardize experimental operations and increase the repeatability and comparability of experimental results.

[0003] The vascular injection device has developed from a simple tool to a modern, convenient and accurate complete set of injection instruments. The existing simple vascular injection device mainly includes an animal fixation device, which includes directly buckling the animal in a beaker or cage. The use of this device can restrict the movement of small animals and only expose the injection position at the tail. However, due to the lack of the assistance of the tail light, the operator's skill proficiency is required to be high when performing vascular injection.

[0004] In order to improve the success rate of tail vein injection, some relatively mature vascular injection instruments have been gradually developed. The existing complete set of vascular injection devices includes fixing devices, tail irradiation lamps and other accessories. The tail irradiation lamp is generally connected to the power supply through an external connection line. However, in actual use, when the animal is restrained or injected, the pain and stress response are aggravated, resulting in more excrement. The instrument is repeatedly used and disinfected with disinfectant, which makes the connection line easily damaged, and then causes the tail irradiation lamp to malfunction, which reduces the service life of the instrument and affects the experimental process.

[0005] Therefore, there is an urgent need for an integrated injection device that can meet the basic needs of injection, is easy to operate, and prevents disinfectant and animal excrement from corroding the connecting line. Utility Model Content
