Abstract
The utility model discloses a self-destroyed injector which comprises a pipe body, a pipe mouth, a rubber plunger and a plunger rod, wherein the front part of the plunger rod is provided with a push block of the plunger, the rubber plunger is hollow, the upper end surface of the rubber plunger is provided with a sleeve hole of which the hole diameter is slightly smaller than the diameter of the push block, the push block of the plunger penetrates through the sleeve hole and is sheathed on the plunger; the bottom of the inner surface of the pipe body is fixed with a simple body of which the upper end of is provided with a sharp knife edge; a push block at the bottom of the plunger rod is hollow, and the side wall of the plunger rod at the outer part of the plunger is provided with a hole which is communicated with the hollow push block to form an air guiding pipe. The utility model has the advantages that the simple body with the knife edge is arranged at the bottom of the inner surface of the pipe body, and the air guiding pipe is arranged on the plunger rod so that the syringe is immediately destroyed after the syringe is used once. The utility model has the advantages of simple structure, convenient operation, easy machining and low cost.
Description
Technical field
This utility model relates to a kind of syringe, particularly relates to a kind of self-destruction syringe.
Background technology
Existing self-destruction syringe mainly comprises an end and has the syringe of pin pass and the plunger of having plunger rod, this plunger rod has a release unit that links to each other with plunger or plunger rod, this release unit just takes off after syringe uses first and splits, to guarantee that syringe can not be used again, described release unit comprises and has at least one with the cam that extends obliquely with respect to the syringe axial line on another member or the member of the cooperative cam-follower of chute, cam or chute link to each other at the axially extended groove of one end with an end opening that faces toward this member, and cam or chute face the block that is provided with a pin with an end of described groove junction.Such structural manufacturing process more complicated is not easy to processing.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of simple in structure, easy self-destruction syringe of production and processing is provided.
The purpose of this utility model is achieved by the following technical programs.
A kind of self-destruction syringe, it comprises body, ozzle, rubber plunger and plunger rod, described plunger rod front portion is the plunger jacking block, rubber plunger hollow, the trepanning that an aperture is slightly less than the jacking block diameter is opened in its upper surface, the plunger jacking block passes trepanning and is enclosed within on the plunger, it is characterized in that: a cylindrical shell is fixed in described body inner face bottom, the upper end of cylindrical shell is sharp blade, described plunger rod bottom jacking block hollow and perforate on the plunger rod sidewall of plunger outside, perforate on the plunger rod sidewall is connected with the jacking block of hollow, to form air conduit.When plunger rod promoted plunger to the body bottom, the blade on the cylindrical shell can be cut plunger and wear, and air conduit is communicated with the body of plunger bottom, thereby make syringe can not realize aspiration medicinal liquid, was about to syringe and damaged, and can not reuse.
Described blade is the V-arrangement blade, so that rubber plunger is easier to be cut open.
Described blade is a serrated edge.
Described cylindrical shell and ozzle over against, cylindrical shell and body joining part leave the slit, so that plunger comes downwards to body when bottom, even the plunger rubber that downcuts has stopped up cylindrical shell, also the intravital medicinal liquid of pipe all can have been injected.
Described cylindrical shell is positioned at the central authorities of body inner face bottom.
Described cylindrical shell height is greater than the thickness of rubber plunger bottom.
This utility model with prior art advantage mutually is: establishes the cylindrical shell of a band blade in body inner face bottom, and on plunger rod, establishes an air conduit, and just can syringe is promptly destroyed after once using, it is simple in structure, easy to operate, handling ease is at the bottom of the cost.

The specific embodiment
Below in conjunction with specific embodiment this utility model is further described.
Embodiment one
As Fig. 1, Fig. 2, structure shown in Figure 5, the self-destruction syringe of present embodiment comprises body 1, ozzle 2, rubber plunger 3 and plunger rod 4, described plunger rod 4 front portions are plunger jacking block 41, rubber plunger 3 hollows, the trepanning 31 that an aperture is slightly less than plunger jacking block 41 diameters is opened in its upper surface, plunger jacking block 41 passes trepanning 31 and is enclosed within on the plunger 3, the cylindrical shell 5 of a height a little more than the rubber plunger bottom thickness fixed in described body 1 inner face bottom on the position of ozzle 2, cylindrical shell 5 leaves slit 6 with body 1 joining part, the upper end of cylindrical shell 5 is sharp V-arrangement blade 51, described plunger jacking block 41 hollows and perforate 42 on plunger rod 4 sidewalls of plunger 3 outsides, perforate 42 on the plunger rod sidewall is connected with the plunger jacking block 41 of hollow, forms air conduit 43.When plunger rod 4 promoted plunger 3 to the body bottom, the blade on the cylindrical shell 5 can be cut plunger and wear, and air conduit 43 is communicated with the body of plunger 3 bottoms, thereby make syringe can not realize aspiration medicinal liquid, was about to syringe and damaged, and can not reuse.
Embodiment two
As Fig. 3～structure shown in Figure 5, the difference of the self-destruction syringe of present embodiment and embodiment one is: described ozzle 2 is positioned at the edge of body 1 bottom, and described cylindrical shell 5 is positioned at the central authorities of body 1 inner face bottom, and the blade 51 on it is a serrated edge.
The mode that this utility model is not limited to enumerate in the foregoing description is so long as the disclosed scheme of utility model content part all can be implemented in this description.
