Description

mouse ear sampler

technical field

The utility model relates to the technical field of test instruments, in particular to a mouse ear slice sampler.

Background technique

Mouse auricle swelling test is one of the commonly used methods to study whether drugs have anti-acute inflammation. It has the characteristics of simple test operation, stable model, low cost and intuitive indicators. Ear sampling is one of the key steps in the test, which is directly related to the accuracy of the test. At present, commonly used ear piece collection tools include rubber plug puncher, manual ear puncher, and electric ear puncher. The rubber plug punch is the most widely used. The method is to use the rubber plug punch to punch 6-9mm circular ear pieces in the same part of the two ears, and then weigh and calculate to evaluate the anti-inflammatory effect of the drug. It often happens that the left and right lugs are of different sizes, uneven edges, and the relative positions of the two lugs are not the same. The pierced lugs still need to be pulled out from the punch with the help of tweezers and other tools, which is time-consuming and laborious, and the accuracy of the results is poor. . When using the manual ear inflator, you need to pull it up through the handle first, which is laborious, and the ear pieces are prone to slipping. The left and right ear pieces are different in position, so that the test cannot correctly reflect the effect of the drug. Although the electric ear swelling ear-beater is easy to operate, its cost is relatively high, which is unfavorable for popularization.
