Multifunctional mouse tail intravenous injection auxiliary assembly

Abstract

The invention relates to a multifunctional mouse tail intravenous injection auxiliary assembly. The multifunctional mouse tail intravenous injection auxiliary assembly comprises an injection platform and a fixing structure used for fixing a mouse. The injection platform comprises a supporting plate and a rotating plate, and the first end of the rotating plate and the first end of the supporting plate are rotationally connected through a connecting structure; the fixing structure comprises a mouse body fixing structure located on the upper surface of the rotating plate and a mouse tail fixing structure located at the first end of the rotating plate. Bulges and recesses are arranged on the upper surface of the rotating plate at equal intervals, and the mouse body fixing structure is arranged to be an adapter matched with the bulges and the recesses for use; a sleeve for fixing a mouse is arranged in the adapter; the rat tail fixing structure is a fixing clamp arranged at the first end of the rotating plate, a round hole is reserved in the middle of the fixing clamp, and the upper end and the lower end of the fixing clamp are provided with pits or protrusions corresponding to the protrusions or the pits in the rotating plate. The connection between the adapter and the rotating plate is ensured through the protrusions and the recesses arranged on the adapter and the rotating plate, the mouse is fixed in the adapter, and the mouse tail is fixed through the sleeve and the fixing clamp.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional rat tail vein injection auxiliary component. Background technique [0002] Rats are commonly used experimental animals in medical research. They can be divided into rats, mice, nude mice, etc. They are widely used in experiments in pharmacology, pathology, and pathobiology. [0003] During the experiment, the establishment of rat tail vein access is the only way for experimental research, which involves multiple links such as anesthesia of model mice, blood sample extraction, and drug intervention. Therefore, the success of rat tail vein puncture directly affects the experimental process. When performing mouse tail vein puncture injection, it is the first choice. The experimenter needs to grasp carefully, and the injection position is appropriate to prevent being bitten by it, so as to ensure the safety of scientific research experiments; Ho...

Therefore, the success of rat tail vein puncture directly affects the experimental process. When performing mouse tail vein puncture injection, it is the first choice. The experimenter needs to grasp carefully, and the injection position is appropriate to prevent being bitten by it, so as to ensure the safety of scientific research experiments; However, because the mice are struggling violently, the experimenters are not easy to fix the mice, and it is inconvenient to adjust the angle height of the platform used to fix the mice, and it is impossible to accurately grasp the injection position, resulting in too deep puncture or deviation of the puncture angle, resulting in the death of the mice; At present, the success rate of tail vein puncture in rats is 80%, and the success rate of tail vein puncture in mice is only 60%. If there are many mice, there will be a problem of long dosing intervals, which cannot meet the operational requirements of the experimenters, and the cost of purchasing multiple devices at the same time is too high; in addition, when the existing tail vein injection device fixes the mice, the tail is fixed. The distance between the fixed platform and the mouse body is too long, and there is a defect that 1 / 3 of the length of the mouse tail cannot be injected
