Abstract

The utility model discloses an automatic-disabling syringe which comprises a needle cylinder and a pushing rod body placed in the needle cylinder. The automatic-disabling syringe is characterized in that a break-off point is arranged on the pushing rod body, and a ring of groove is formed in the position, close to the end portion of the pushing rod body, of the pushing rod body so as to enable the end portion of the pushing rod body to form a convex cap. The automatic-disabling syringe can be broken off from the break-off point by the fact that the pushing rod body is drawn out with strength through the convex cap fixed on the end portion of the pushing rod body, the use is convenient, the automatic disabling is thorough, and the practicability is high.

Description

Self-destruction syringe

Technical field

This utility model relates to a kind of syringe, is specifically related to self-destruction syringe, belongs to IPC classification A61M5 technical field.

Background technology

Self-destruction syringe is can prevent reusable disposable syringe product after using, kind is various, after injection is complete, rely on craft or mechanical forces, push rod can not be extracted out in syringe, reach self-locking, or the sealing property of piston is destroyed, perhaps the push rod of syringe can be pushed off, and finally reaches and prevents the purpose that reuses.

Having at present a kind of self-destruction syringe to establish snap point by push rod realizes, this syringe is when self-destruction, state in the time of push rod need to being withdrawn into to the full injection of syringe absorption, then fracture the bar core of push rod, makes like this bar head of push rod there is no the push-and-pull of bar core and reach the self-destruction purpose, but, injection during syringe also has residually in this case, or the bar core fractures and can detach syringe by connecting-rod cap during self-destruction, and self-destruction is convenient not, practicality is not good, defectiveness.

Summary of the invention

The purpose of this utility model exactly the self-destruction syringe self-destruction be provided with snap point is convenient not, not good, the defective problem of practicality in order to solve.

The technical scheme that this utility model will be dealt with problems is as follows:

Self-destruction syringe, comprise syringe, be positioned over the push rod body of rod in syringe, and it is characterized in that: the described push rod body of rod is provided with snap point, near on the push rod body of rod of push rod end of body, being provided with a circle groove, makes the push rod end of body form a protruding cap.

Described protruding cap is exposed to outside syringe when the push rod body of rod and syringe coupling.

Between the tabular cauda of described snap point by the fork-shaped core print of the bar core segment that forms the push rod body of rod and club head portion, by some burs or projection, be formed by connecting.

Described syringe end can be overlapped adapter sleeve is arranged, and in described adapter sleeve, establishes screw thread.

By the described syringe of screwed screw type adapter sleeve, can be fixedly connected with fluid delivery apparatus, play steady fixation.

The beneficial effects of the utility model are as follows:

Compared with prior art, adopt the self-destruction type needle cylinder of this utility model structure, by the fixing protruding cap of push rod end of body, firmly the push rod body of rod is pulled out and can be fractureed from snap point, easy to use, self-destruction is thorough, and is practical.

The accompanying drawing explanation:

Fig. 1 is generalized section of the present utility model.

Fig. 2 is this utility model push rod body structure schematic diagram.

The specific embodiment:

Below in conjunction with accompanying drawing, this utility model is done to further detailed elaboration.

Consult Fig. 1, Fig. 2, self-destruction syringe, comprise syringe (1), be positioned over the push rod body of rod (2) in syringe (1), the described push rod body of rod (2) is provided with snap point (3), on the push rod body of rod (2) near the push rod body of rod (2) end, is provided with a circle groove (4) and makes the push rod body of rod (2) end form a protruding cap (5).

By fixing protruding cap (5), snap point (3) disconnects, and can complete easily self-destruction, and self-destruction is thorough, and is practical.

Described protruding cap (5) is exposed to outside syringe (1) when the push rod body of rod (2) mates with syringe (1).

Like this, having sprayed medicament, be the push rod body of rod (2) while being pushed into the least significant end of syringe (1), by external device, can well fix protruding cap.

Described snap point (3) is by between the tabular cauda (9) of the fork-shaped core print (7) of the bar core segment (6) that forms the push rod body of rod (2) and club head portion (8), by some burs (10) or projection (figure is mark), being formed by connecting.

Described syringe (1) end can be overlapped adapter sleeve (11), and described adapter sleeve is established screw thread in (11).By the described syringe of screwed screw type adapter sleeve (11) (1), can be fixedly connected with fluid delivery apparatus, play steady fixation, with respect to the adapter sleeve of existing straight mouthful, more reasonable in design, and desirable lower joint sleeve (11) while not needing to stablize.

Operation principle of the present utility model is as follows:

During use, after the adapter sleeve (11) that is nested with by syringe (1) end and outside equipment connection, syringe normally uses, after use is over, structure by external connection grasps protruding cap, with pulling the push rod body of rod (2), because the push rod body of rod (2) is comprised of bar core segment (6) and club head portion (8), between the two snap point is at the active force of external force for this reason, bur (10) is easy to just disconnect, thereby bar core segment (6) is separated with club head portion (8), reached the purpose of syringe self-destruction.

It is only below better embodiment of the present utility model; should be understood that; on the basis that does not break away from this utility model ultimate principle; for those skilled in the art; these improvements and modifications can also be improved appropriately and retouch, within all should drop on the claimed scope of this utility model.

Claims
