Abstract
Needle stand formula safe self-breaking syringe of windowing of the present utility model, including syringe, the core bar that is slidably mounted in syringe, the piston being arranged on core bar, it is arranged on the needle stand of its upper end, the needle tubing being fixed on needle stand, it is characterized in that, needle stand is provided with window, and core bar upper end is provided with the dop can being stuck at window.The beneficial effects of the utility model are, simple in construction, esy to use, safe and reliable, and this self-destroyed syringe connects structure owing to have employed needle stand of windowing, and has reliable during pumpback, it is to avoid dop slips with needle stand, it is impossible to pumpback, causes the risk that self-destroying function is failed；The shoulder that struts on core bar also ensure that needle stand and the smooth pumpback of needle tubing, and after pumpback, the groove in needle tubing blocks the snap ring on core bar, after weak section breaks disconnected core bar, core bar is effectively ensured can not be pushed up, needle tubing can not run up, and needle tubing can only be hidden in syringe, prevents from stabbing medical personnel.
Description
Technical field
This utility model belongs to syringe art, relates to one and windows needle stand formula safe self-breaking syringe.
Background technology
1. CN101342398 Ou Te medical treatment (Chinese) company limited, safe self-breaking syringe, by plug by needle stand needle tubing
Hale motor process unreliable, have needle stand can not pumpback, the risk that the motion of plug and needle stand slips.
2.CN104857603A Kangbao Medical Equipment Co., Ltd., Jiangsu, disposable safety self-breaking injector, the knot of product
Structure design: needle stand can not pumpback, after having injected, needle tubing can not be effectively protected, it is impossible to is truly realized anti-acupuncture, makes
The most exposed outside with rear needle point, medical personnel and patient can be stabbed.
3.CN2629727 Wuxi Yushou Medical Equipment Co., Ltd, single use self-destroyed syringe, needle stand can not
Pumpback, needle tubing can not be effectively protected, it is impossible to is truly realized anti-acupuncture.
Summary of the invention
This utility model is in order to make up the deficiencies in the prior art, it is provided that a kind of simple in construction, esy to use, safe and reliable
Needle stand formula safe self-breaking syringe of windowing.
This utility model is achieved by the following technical solution:
Needle stand formula safe self-breaking syringe of windowing of the present utility model, including syringe, the core bar that is slidably mounted in syringe,
The piston being arranged on core bar, is arranged on the needle stand of its upper end, the needle tubing being fixed on needle stand, it is characterised in that on needle stand
Being provided with window, core bar upper end is provided with the dop can being stuck at window.
Syringe lining is accompanied between syringe and needle stand.
Being provided with the support column preventing needle stand from gliding inside syringe, core bar is provided with and struts support column and make what needle stand glided to strut
Shoulder.
Core bar middle and upper part is provided with a circle snap ring, and syringe lower inside is provided with the twice draw-in groove for blocking snap ring.
The protected cap of needle tubing outer cover；Protective cap is arranged on syringe lining.
Core bar is provided with the weak section being easy to fracture.
The beneficial effects of the utility model are, simple in construction, esy to use, safe and reliable, and this self-destroyed syringe is owing to adopting
Connect structure with needle stand of windowing, have reliable during pumpback, it is to avoid dop slips with needle stand, it is impossible to pumpback, causes self-destruction merit
The risk that energy is failed；The shoulder that struts on core bar also ensure that needle stand and the smooth pumpback of needle tubing, the groove card in needle tubing after pumpback
Living the snap ring on core bar, after weak section breaks disconnected core bar, core bar is effectively ensured can not be pushed up, and needle tubing can not run up, pin
Pipe can only be hidden in syringe, prevents from stabbing medical personnel.Each parts of this safe self-breaking syringe are the most easily processed, and assemble the most very
Easily realizing automated production, mass production, therefore this syringe has reliable, easily processes, the spy that production efficiency is high
Point.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Fig. 1 is overall diagram, and Fig. 2 is partial enlarged drawing, and Fig. 3 is needle stand sectional view, and Fig. 4 is needle stand axonometric chart, and Fig. 5 is syringe
Outline drawing, Fig. 6 is syringe sectional view.
In figure, 1 protective cap, 2 needle tubings, 3 needle stands, 4 syringe linings, 5 syringes, 6 core bars, 7 pistons, 8 windows, 9 dops,
10 support columns, 11 strut shoulder, 12 snap rings, 13 draw-in grooves.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.
Needle stand formula safe self-breaking syringe of windowing of the present utility model, including syringe 5, the core bar that is slidably mounted in syringe
6, the piston 7 being arranged on core bar, it is arranged on the needle stand 3 of its upper end, the needle tubing 2 being fixed on needle stand, needle stand is provided with window
Mouth 8, core bar upper end is provided with the dop 9 can being stuck at window.
Syringe lining 4 is accompanied between syringe and needle stand.
Being provided with the support column 10 preventing needle stand from gliding inside syringe, core bar is provided with and struts the support that support column makes needle stand glide
Open shoulder 11.
Core bar middle and upper part is provided with a circle snap ring 12, and syringe lower inside is provided with the draw-in groove 13 for blocking snap ring.
The outside protected cap of needle tubing, protective cap 1 is arranged on syringe lining.
Core bar is provided with the weak section being easy to fracture.
When not using, needle tubing is fixed on and windows in needle stand, and needle stand of windowing is enclosed within syringe lining, and syringe lining is tight with syringe
Close fit, as shown in Figure 1, is cased with protective cap on syringe lining；Core bar is assemblied in syringe with the assembly of piston, does not starts to make
The dop of used time core bar and and needle stand between leave a certain distance
When beginning to use, take out the protective cap outside needle tubing, in the needle tubing of self-destroyed syringe is reached medicinal liquid bottle, extract medicine
Liquid, core bar is moved rearwards by together with plug, and medicinal liquid enters in syringe, when piston movement to predetermined graduation mark, core bar with
Piston stop motion.
Self-destruction, when an injection is needed, promotes core bar piston advances forward, until medicinal liquid has all been injected, and core bar and piston
When moving to syringe head, the dop of core bar is inserted into windows in needle stand, and the dop of core bar cylinder below (i.e. struts shoulder simultaneously
Portion) can strut prevent on syringe injection time window needle stand retreat two support columns (holder), from injection after having injected
Syringe is exited at position, then draws and on the other hand catches syringe, another pull dynamic core bar by hand position rearward movement, at this moment core bar
Dop will drive needle stand needle tubing to move in syringe, and final needle tubing is retracted and is fixed in syringe, the snap ring quilt of core bar front end
Being fixed in the draw-in groove at syringe rear portion, core bar is immovable.
Fracture core bar, and core bar is thoroughly fixed from activity, and needle tubing is also limited in syringe, reaches the mesh of anti-acupuncture
's.
The effect of each parts:
Protective cap: be fixed on syringe lining, protects needle tubing；
Needle tubing: be fixed on needle stand, plays puncture, the effect of transmission medicinal liquid；
Window needle stand: fixing connect needle tubing, and be linked in needle tubing lining；
Needle tubing lining: with window needle stand and protective cap coordinates fixing；
Syringe: core bar piston is assemblied in its cylinder, syringe lining is fixed on its end, and moves in its cylinder；
Core bar: after assembling with piston, assembly reassembles in syringe；
Piston: move in syringe after assembling with core bar, seals liquid and measures the capacity of liquid.
