Abstract
A simple type safe injector comprises a needle, a pintle and an injection syringe; the injector is characterized in that the internal side of the lower end of the injection syringe is provided with a micro-bulge and the upper end of the injection syringe is provided with a syringe carotid, inside which a needle seat is positioned. An inner cam ring that presses against the needle seat is positioned at the upper mouth of the syringe carotid, the upper end of which is provided with the needle, and the internal side of which is provided with a micro-flute; a sealing ring is positioned inside the micro-flute, sealing the internal side of the syringe carotid and the external side of the needle seat; the upper end of the pintle is provided with a piston, the external side of which is provided with two piston flutes; a sealing snare is positioned inside the piston flute, doubly sealing the external side of the piston and the internal side of the injection syringe; a barb body is arranged at the middle of the piston. The product has the advantages of simple structure, convenient manufacture, safety and reliability, little investment, quick effectiveness and easy popularization and use.
Description
Technical field:
This utility model relates to a kind of disposable syringe, relates more specifically to a kind of simple type medical safe syringe that can make the needle retractable damage.
Background technology:
Use more disposable syringe at present, behind the contact sick body, outside contaminated syringe needle is exposed to, medical worker or cleaning employee do not note slightly, very easily infected by needle sting, according to present disclosed this technical scheme, its shortcoming is: product structure complexity, processing request height, operate inconvenience, easily leakage and error take place, therefore be difficult to promote the use of.
Summary of the invention:
This utility model provides a kind of simple type safety injector, for having overcome above-mentioned shortcoming, guaranteed that from easy structural design this syringe can only disposablely use, can reach the purpose of thorough damage syringe reliably easily with needle retractable again after finishing using.The technical solution of the utility model is: a kind of simple type safety injector comprises: syringe needle, pintle, syringe; It is characterized in that: establish a micro-bulge on the inboard of syringe lower end, a neck is put on the top of syringe, needle holder places in the neck, the convex circle that offsets with needle holder that is provided with suitable for reading of tube neck, a syringe needle is put on the top of tube neck, establish a micro groove on its inboard, the built-in sealing ring of micro groove, make between the outside of the inboard of a neck and needle holder and seal, a piston is established on the top of pintle, and its outside is provided with two pistion recess, the built-in sealing snare of pistion recess, make double-layer seal between the inboard of the outside of piston and syringe, a barbed body is established in the centre of piston.This utility model is simple in structure, easy to make, safe and reliable, and small investment, instant effect are promoted the use of easily.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a collapse state sketch map of the present utility model.
Wherein: 5 necks of 1 syringe needle, 2 pintle 3 syringes, 4 micro-bulges, 6 needle holder, 7 convex circles, 8 micro grooves, 9 sealing rings, 10 pistons, 11 pistion recess, 12 sealing snares, 13 barbed bodies, 14 oblique arms
The specific embodiment:
As shown in Figure 1: this utility model comprises: syringe needle 1, pintle 2, syringe 3; Establish a micro-bulge 4 on the inboard of syringe 3 lower ends, a neck 5 is put on the top of syringe 3, needle holder 6 places in the neck 5, the convex circle 7 that offsets with needle holder 6 that is provided with suitable for reading of tube neck 5, a syringe needle 1 is put on the top of tube neck 5, establish a micro groove 8 on its inboard, micro groove 8 built-in sealing rings 9, make between the outside of the inboard of a neck 5 and needle holder 6 and seal, a piston 10 is established on the top of pintle 2, and its outside is provided with two pistion recess 11, pistion recess 11 built-in sealing snares 12, make double-layer seal between the inboard of the outside of piston 10 and syringe 3, a barbed body 13 is established in the centre of piston 10.
As shown in Figure 2: oblique arm 14 length of barbed body 13 of the present utility model enter in the neck 5 barbed body 13 greater than the internal diameter of needle holder 6, and the two ends of its oblique arm 14 tiltedly are worn on the inwall of a neck 5, can not come off.
As Fig. 1, shown in Figure 2: during this utility model work, as long as pintle 2 is firmly pushed ahead, medicinal liquid in the syringe 3 is discharged from syringe needle 1, when pintle 2 vertical pistons 10 arrive at the tube neck 5 of syringe 3, medicinal liquid in the syringe 3 drains, piston 10 intermediary barbed bodies 13 enter in the needle holder 6, as long as pintle 2 is pulled back, oblique arm 14 two ends of barbed body 13 tiltedly are worn on the inwall of needle holder 6, drive needle holder 6, make in its syringe needle 1 income syringe 3, and needle point swings to the side in the syringe 3, and push ahead pintle 2 this moment again, with syringe needle 1 bending, thereby reached damage syringe needle 1, the purpose of disabling syringe.
