Embodiment
It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
As Figure 1-5.A kind of one-shot injector, including cylinder 1, the lower end of cylinder 1 is provided with needle stand 2, in cylinder 1
The push rod 3 of setting, the lower end of the push rod 3 are provided with contiguous block 4, and the lower end of contiguous block 4 is provided with head 5, and piston 6 passes through company
Connect block 4 to be connected with push rod 3, piston 6 can move with push rod 3 in cylinder 1, be provided with the outer cylinder of the lower end of head 5
Annular groove 7, is provided with elastic card claw 1 on the inwall of needle stand 2, and elastic card claw 1 is connected to the annular groove in head 5
7 realize self-destruction, and sheath 9 is provided with outside the needle stand 5 of the lower end of cylinder 1, and the sheath 9 and cylinder 1 are integral type structure, in sheath
The lower end of 9 inwall is provided with elastic card claw 2 10, and elastic card claw 2 10 is circumferentially uniform along the inwall of sheath 9.Purl set 11 it is upper
End is provided with annular convex edge 12, and purl set 11 is stretched into sheath 9 from the lower end of elastic card claw 2 10, and elastic card claw 2 10 is fastened on
The locking to syringe needle is realized on the baseplane of annular convex edge 12.
The present invention can also not only lock, greatly improve to being locked between push rod and cylinder 1 to syringe needle
The effect of self-destruction.
The self-destruction that the present invention is carried out to all parts of syringe, the possibility reused prevented completely, avoid because
Reuse one-shot injector and cause the generation of viral cross transmission and infection.
Circumferentially be evenly equipped with order to thoroughly carry out self-destruction to syringe, on the baseplane of piston 6 of the present invention two with
On self-destruction groove 13, relevant position is provided with the one-to-one self-destruction pricker 14 of quantity on cylinder 1, during self-destruction, self-destruction pricker 14
It is plugged in self-destruction groove 13.After piston 6 is moved to bottom, self-destruction pricker 14 is located in self-destruction groove 13, destroys the close of piston 6
Feng Xing, realize self-destruction.
In order that self-destruction groove 13 can be corresponding exactly with the position of self-destruction pricker 14, the section of described push rod 3 is in cross
Shape, the axially disposed position line for having one or more in the side wall of cylinder 1, one of side and position line on push rod 3
Alignment just can realize the positioning of self-destruction groove 13, self-destruction pricker 14.
It is described in order to avoid lines excessively influence the normal use of syringe due to being provided with graduation mark on cylinder 1 itself
Position line sets one, and the position line is the graduation mark on syringe.Specifically, it is that root is axial along syringe on graduation mark
The line of setting.
Because the present invention is provided with multiple self-distruction structures, in order to prevent that self-destruction occurs in assembling process, cause product
