Specific embodiment
The utility model is described in further detail presently in connection with drawings and examples, these attached drawings are simplified
Schematic diagram only illustrates the basic structure of the utility model in a schematic way, therefore it only shows structure related with the utility model
At.
As Figure 1-Figure 4, the fixed device of a kind of tail vein injection, including pedestal 10, is arranged in consolidating on pedestal 10
Safety barrel 12 and fixed mechanism, fixed mechanism is including the first limit assembly, the second limit assembly and is located at the second limit group
Two third limit assemblies of part two sides, the first limit assembly include limit plate 14, the door shape bar 16 being fixed on limit plate 14
And it is provided with the first limiting slot 18 on limit plate 14, the second limit assembly includes limiting net 20, one end with limit net 20
Fixed sliding block 22, the other end and the door shape bar 16 for limiting net 20 are fixed, and each third limit assembly includes limit base 24, opens up
The both sides of the second limiting slot 26 on limit base 24, limit net 20 are respectively implanted in two the second limiting slots 26.Rat-tail is put
It sets in the first limiting slot 18, the lower part and side of rat-tail are limited by the first limiting slot 18, and the top of rat-tail is limited net 20
It limits, limit net 20 is limited by the second limiting slot 26, and such rat-tail is limited by comprehensive, and rat-tail is restricted area
Greatly, good fixing effect convenient for intravenous injection, and avoids causing to damage to rat-tail.
The bottom end of the preferred sliding block 22 of the utility model is fixed with elastic projection 28, is realized by elastic projection 28 by rat-tail
Blood in preceding part rushes to the rear part of rat-tail, makes caudal vein blood vessel dilatation, while can also push down rat-tail, convenient for syringe needle into
Enter, improves injection accuracy.
In order to avoid the damage to rat-tail, the preferred elastic projection 28 of the utility model is made of rubber or silica gel material.
The utility model preferably the first limiting slot 18 is arc-shaped, further increase with rat-tail contact area, improve to mouse
The fixed stability of tail.
The utility model preferably limits net 20 and includes limit net ontology 30, is separately fixed at limit 30 both sides of net ontology
Two struts 32, two struts 32 are respectively implanted in two the second limiting slots 26.In order to further limit strut 32, avoid limiting
The displacement of net 20, improves fixed effect, and the preferred strut 32 of the utility model and 26 shape of the second limiting slot cooperate.Further preferably branch
Bar 32 is hard elastic strut, can be bent, be provided simultaneously with certain intensity, convenient for limit in the second limiting slot 26.
