Animal Venipuncture Precise Quantification Device

Abstract

The invention provides an accurate quantification device for animal vein puncture dosing. The device comprises a syringe needle part, a three-fork connector part and two injectors with scales. The syringe needle part comprises a syringe needle, a syringe needle protection sleeve, a needle handle and a syringe needle hose. A three-fork connector part body is a three-fork hose provided with three end openings, wherein the first end opening is connected with a first hose of the three-fork hose, the second end opening is connected with a second hose of the three-fork hose, and the third end opening is connected with a third hose of the three-fork hose. The first end opening is used for being connected with the syringe needle hose of the syringe needle part, the second end opening and the third end opening are used for being connected with the injectors, and the second hose and the third hose are provided with flow control pulleys. The injectors are used for injecting fluid.

Description

technical field [0001] The invention relates to a precise quantitative device for venipuncture of animals. Background technique [0002] When conducting animal experiments or treating animals, venipuncture or blood collection techniques are often used, usually using disposable syringes (see appendix figure 1 ) directly administer or draw blood. For relatively small animals, such as rats, mice tail veins, rabbit ear veins, etc., due to the small blood vessels, it is difficult to directly use a syringe for venipuncture, which often causes blood vessels to be pierced or the injection needle does not enter. If there is no symptom in this situation, the following consequences will be caused when the medicine is continued: 1. The drug solution leaks (does not enter the blood vessel), which changes the route of administration; 2. The dosage is wrong, causing experimental errors; 3. Waste of precious drugs; 4. Some special drugs will cause experimental animals to be scrapped (such...

Problems solved by technology

For relatively small animals, such as rats, mice tail veins, rabbit ear veins, etc., due to the small blood vessels, it is difficult to directly use a syringe for venipuncture, which often causes blood vessels to be pierced or the injection needle does not enter. If there is no symptom in this situation, the following consequences will be caused when the medicine is continued: 1. The drug solution leaks (does not enter the blood vessel), which changes the route of administration; 2. The dosage is wrong, causing experimental errors; 3. Waste of precious drugs; 4. Some special drugs will cause experimental animals to be scrapped (such as rat tail margin intravenous injection of doxorubicin for kidney disease model modeling, if the drug does not directly enter the blood vessel and leakage occurs, it will cause The tail of the rat falls off, and it is impossible to inject other drugs through the tail margin vein again, which affects the follow-up experiment) and even affects the parallelism of the entire experiment, resulting in the waste of the entire batch of animal data. It is necessary to re-purchase the entire batch of animals for experiments, which is a serious waste of time and money.

In addition, this method is not easy to fix the injection needle, and it is easy to fall off. The toxic agent will pollute the test bench and affect the safety of the operator.
