Description
Technical field
It is a kind of tail vein injection haemostatic clamp specifically the present invention relates to technical field of medical instruments.
Background technology
Mouse is the animal pattern commonly used in a kind of medical research, can be divided into rat, mouse, nude mice according to requirement of experiment difference
Deng polytype.After mouse modeling, tail vein injection is the most frequently used intervention path.Caudal vein thickness is uneven, injects difficulty or ease journey
Degree differs, and the success or not of tail vein injection directly determines the success rate of model.At present, experienced laboratory technician carries out small
Tail vein injection success rate does not reach 80%.This means the model mouse for having significant proportion can not be tested effectively, make
Into huge waste, experimental cost is improved.
During tail vein injection, first have to carry out Pressur hemostatic in rat-tail heel, expand caudal vein, then carry out tail vein
Puncture, fix.But, during path is set up in caudal vein puncture, there is Railway Project and deficiency：
First, usually required in the prior art without the Pressur hemostatic apparatus for being exclusively used in tail vein injection in practice operation
Assistant's hand or rubber band clamping rat-tail root complete Pressur hemostatic, when caudal vein is thinner, can not cause pressurization dynamics not enough or not
Uniformly, cause the effect of tail vein ligation, hemostasis, expansion undesirable.
Secondly, complete tail vein to puncture, assistant's decompression is needed before being injected, loosens ligation band.Depressurize, loosen ligation band
During be easy to swing rat-tail, injection needle, which punctures tail vein, causes operation failure, finally successfully loses vertical.
Further, when carrying out model mouse experiment, tail vein injection frequency of use is higher, and per injection is required for outfit to help
Hand.Do not require nothing more than assistant so and operator's tacit agreement degree is high, and add human cost again.Therefore, if a kind of real
Test animal apparatus fast and accurate pressurization can be carried out to different caudal vein and ligature, and can be convenient, stable decompression,
The equipment for completing tail vein Path Setup, can be greatly improved tail vein injection success rate, reduction experiment consumptive material, save manpower into
This.
