Abstract
The utility model provides a self-destructible vaccine syringe. The self-destructible vaccine syringe comprises a syringe needle, an outer sleeve, a piston, a core rod and a lock catch. The lock catch is secured at the outer sleeve via a positioning ring and a positioning groove. A circular ring is arranged on the core rod. The length L2 from the circular ring to the bottom of the piston is smaller than the length L1 from ratchets of the lock latch to the bottom end of the outer sleeve. The self-destructible vaccine syringe is characterized in that the lock latch is provided with the elastic ratchets; the length L4 from a hand-laying portion of the core rod to the bottom of the piston is smaller than the length L3 from an opening of the outer sleeve to the bottom end of the outer sleeve; an external diameter of the hand-laying portion of the core rod is smaller than the internal diameter of an opening of the outer sleeve; a double self-locking function come into forces after medical liquid is injected; and a self- destructible function is exerted because the syringe cannot be used any longer. The self-destructible vaccine syringe has following beneficial effects: the self-destructible vaccine syringe is advantaged by being simple in structure, reliable in connection, convenient in application, production and assembly and good in stability and safety; the self-destructible vaccine syringe is self-destructible after one-time injection; and automated production is achieved.
Description
Technical field
This utility model relates to medical instruments field, particularly a kind of vaccine syringe.
Background technology
Vaccine syringe is a kind of conventional medical apparatus, and it comprises entry needle, overcoat, piston, core bar etc.In order to prevent cross infection, disposable use is more and more subject to people's attention.Conventionally after vaccine syringe uses, without self-desttruction equipment, medical worker may reuse due to carelessness, leaves hidden danger to cross infection, and propagation tends to produce the disease of.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of self-destruction type vaccine injector is provided, and this utility model simple structure connects reliably, and easy to use, stable, production and assembly are convenient, can realize automated production, avoid reusing.
The purpose of this utility model realizes in the following manner:
A kind of self-destruction type vaccine injector, comprises entry needle, overcoat, piston, core bar, snap close; Described snap close is provided with elastic pawl, and snap close is fixing on the coat by locating ring and locating slot; Core bar is provided with annulus, and annulus to the length L 2 of the bottom of piston is less than ratchet on the snap close length L 1 to the bottom of overcoat; On core bar, be less than the length L 3 of overcoat opening part to the bottom of overcoat by hand portion to the length L 4 of the bottom of piston; On core bar, be less than the internal diameter of overcoat opening part by the external diameter of hand portion.
Described core bar and annulus are made up of plastics one-shot forming.
Describedly be provided with hemispherical projections by hand portion.
Described snap close is provided with at least two elastic pawls.
Described snap close is provided with four elastic pawls.
With respect to prior art, this utility model can block annulus by ratchet after the complete medicinal liquid of injector to inject, simultaneously core bar also all enter the inside of overcoat by hand portion, now double self locking comes into force, syringe can not be used again, and realizes self-destroying function.

Reference numeral: entry needle 1, overcoat 2, piston 3, core bar 4, snap close 5, locating slot 21, annulus 41, by hand portion 42, hemispherical projections 43, locating ring 51, elastic pawl 52.
Detailed description of the invention
As shown in Figure 1, this utility model adopts a kind of core bar and embeds the self-destruction type vaccine injector of overcoat inner structure by hand portion, comprising: entry needle 1, overcoat 2, piston 3, core bar 4, snap close 5.As shown in Figures 2 to 5, the suitable location of core bar 4 is provided with one and prevents the annulus 41 that core bar exits, and is provided with hemispherical projections 43 by hand portion 42.Snap close 5 is provided with four elastic pawls 52, is fixed on overcoat 2 by locating ring 51 and locating slot 21.Annulus 41 to the length L 2 of piston 3 bottoms is less than ratchet 52 on snap close 5 length L 1 to the bottom of overcoat 2, on core bar 4, is less than the length L 3 of overcoat 2 opening parts to the bottom of overcoat 2 by hand portion 42 to the length L 4 of piston 3 bottoms.On core bar 4, be less than the internal diameter of overcoat 2 opening parts by the external diameter of hand portion 42.
Syringe is before liquid medicine injection shoots away, and the annulus 41 on core bar 4 can not enter four elastic pawl 52 belows of snap close 5, extracts medicinal liquid, air-discharging identical with ordinary syringe with action of injection.When core bar 4 is pushed into behind overcoat 2 bottoms completely, injecting liquid drug completes, annulus 41 struts four elastic pawls 52 on snap close 5, enter the below of four elastic pawls 52 of snap close 5, four elastic pawls 52 return to original position, block annulus 41, simultaneously core bar 4 also all enter the inside of overcoat 2 by hand portion 42, now double self locking comes into force, and causes core bar again to extract use, realizes self-destroying function.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under this utility model general idea prerequisite; can also make some changes and improvements; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that this utility model is implemented.
