Description
Technical field
This utility model relates to a kind of disposable use self-destroyed syringe, belongs to medical syringe.
Background technology
At present, widely used disposable sterilized syringe in the domestic and foreign hospitals is because its structural reason is said and incomplete disposable characteristics from serviceability.Only needing syringe is adjusted a little just can be from new use.In addition, still owing to its structural reason, the drawing liquid amount of syringe does not have clear and definite restriction, and the medicinal liquid of suction greatly more than the syringe nominal capacity, causes unnecessary waste sometimes, and particularly more valuable medicinal liquid needs strict its drawing liquid amount of control.In a word, the structure of existing injector for medical purpose needs further improvement.
Summary of the invention
The purpose of this utility model is to provide a kind of drawing liquid of limiting the quantity of, and the disposable use self-destroyed syringe that promptly damages after using, to remedy the deficiencies in the prior art.
The purpose of this utility model is to realize like this, it comprises syringe (1), core bar (2), piston (3) and needle tubing (4), it is characterized in that: core bar (2) is provided with lock (6), weak area (7) and liquid-limiting device (8), is provided with locking folder (5) and liquid-limiting clip (9) in the syringe (1).This utility model compared with prior art, its uses reliable convenient, can control the drawing liquid amount, cost is low, self destruction after once use.

Among the figure: 1, syringe, 2, core bar, 3, piston, 4, needle tubing, 5, the locking folder, 6, lock, 7, weak area, 8, liquid-limiting device, 9, liquid-limiting clip, 10, subtract residual plug, 11, needle stand, 12, adhesive.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified:
Referring to accompanying drawing, it comprises syringe 1, core bar 2, piston 3 and needle tubing 4 this utility model, and it is to be provided with lock 6, weak area 7 and liquid-limiting device 8 on core bar 2, is provided with locking folder 5 and liquid-limiting clip 9 in syringe 1.Utilize the spacing purpose that reaches the drawing liquid of to limit the quantity of of 9 pairs of liquid-limiting devices 8 of liquid-limiting clip, utilize locking folder 5 and lock 6 to reach disposable purpose, utilize 7 patient pulling force of weak area to be significantly smaller than the coupling mechanism force of locking folder 5 and lock 6, make core bar 2 easily break, having played disposable use to be the purpose of self-destruction.
In the present embodiment, needle tubing 4 uses adhesive 12 to be bonded in the upper end of syringe 1, and this form structure is simple, and residual quantity is extremely low, and production cost is low.
Another kind of version of the present utility model is seen accompanying drawing 8, it adopts the general entry needle of general band needle stand 11, and its advantage is to change the entry needle of different size, and its shortcoming is to have increased residual quantity, be sort this problem out, in the front end of syringe 1 and needle stand 11, installed one additional and subtracted residual plug 10.
