Study on the design of the experimental rat fixtures and the method of rat tail vein injection / 中国基层医药

ABSTRACT

Objective To provide a fixtures and feasible injection method for rat tail vein injection.Methods SD rats were randomly divided into A group and B group,thirty rats in each group.Rats in group A fixed by a simple and practical experimental rats fixtures.And rats in group B fixed by common plastic drink bottles.Then the tail vein injection experiment was conducted respectively.Results It took one people 31.2 seconds in group A and 33.1 seconds in group B to finish the experiment from capture to fix rats,and took one people 68.4 seconds in group A to finish the experiment from capture to finish the injection,while it couldn't finish in group B.It took two people 25.4 seconds in group A and 25.8 seconds in group B to finish the experiment from capture to fix rats,and took 63.7 seconds in group A and 85.6 seconds in group B to finish the experiment from capture to finish the injection.Conclusion The experimental rats fixtures can increase the success rate of rats tail vein injection,and shorten the injection time.It is a safe and effective method.
