Description

Experimental rat tail vein injection device

Technical field

This utility model relates to a kind of intravenous injection device, is specifically related to a kind of experimental rat tail vein injection device, belongs to the medical teaching instrument field.

Background technology

Mus is a laboratory animal the most frequently used in the medical experiment; relate to the operation of caudal vein drug administration by injection and blood sample collection in a lot of subject experimentatioies through regular meeting, can these two operations determine experiment obtain ideal results smoothly to a great extent.Mus is under normal physiology position, obviously as seen the afterbody blood vessel has four, is respectively: a radicular arteries is respectively arranged on the dorsal ventral side, and respectively there is a radicular vein two sides of back of the body abdomen, the about 1.4mL of the total amount of blood circulation, the tail vein is very tiny, and average diameter is less than (0.6 ± 0.5) mm, therefore, when the Mus tail is carried out intravenous injection, hold and can not finely fix, it is big to cause injecting difficulty, and success rate is low.

The utility model content

The purpose of this utility model is in order to solve when the Mus tail is carried out intravenous injection, to hold and can not finely fix, and it is big to cause injecting difficulty, the problem that success rate is low, and then a kind of experimental rat tail vein injection device is provided.

The technical solution of the utility model is: experimental rat tail vein injection device comprises the Mus box, the afterbody gripper shoe, sponge, the afterbody fixation clamp, lid and a plurality of set bolt, stern notch is offered in the side of Mus box, a plurality of through holes are offered in the front of Mus box, offer a finger on the afterbody gripper shoe and stretch into mouth, one end of afterbody gripper shoe is fixedly mounted on the stern notch place of Mus box, the other end of afterbody gripper shoe is provided with the afterbody fixation clamp, sponge is arranged in the Mus box, the lid lid is contained on the Mus box, wear a set bolt in each through hole, the quantity of through hole is consistent with the quantity of set bolt.

This utility model compared with prior art has following effect: 1. the inside of this utility model Mus box covers lid after putting into sponge, has effectively simulated the sensation of holding, and has prevented the injury to experimental mouse.2. this utility model is offered stern notch 1-1 in the side of Mus box, makes the Mus tail expose, and is convenient to the operation to the Mus tail.3. afterbody fixation clamp of the present utility model and finger stretch into mouth, guaranteed to test and finished by one man operation, need not assistant experiment person helps, saved personnel, every injection about 2min of deadline effectively raises success rate and efficient that caudal vein is injected, the firm health of having fixed Mus, both avoided the experimenter to be hindered, and saved to wear and add muffler, be beneficial to normally carrying out of experiment again by damaged by rats.4. this utility model is simple in structure, and cost is low, and perfect in shape and function is easy to realize.
