Abstract
The utility model discloses an auto disable syringe, comprising a syringe needle, an outer tube, a rubber plug and a core bar; the syringe needle comprises a needle sleeve, a syringe tube and a needle base; the auto disable syringe is characterized in that the front part of the needle base is a combining part matched with the needle sleeve; the outer wall of the middle part is provided with an outer ear; the rear part of the outer ear is provided with a cylindrical or conical combining part; the rear part thereof is provided with an injector capable of piercing the rubber plug; the front part of the outer tube is provided with a neck or threaded groove and a tapered internally-concave round surface matched with the needle base; the rear part thereof is provided with a roll rim; the head of the core bar is provided with an internally-concave groove or locking part matched with the injector of the needle base and a sleeve part of the rubber plug; the rear part of the core bar is provided with a baffle; and a limiting card is installed at the upper part of a button. For the auto disable syringe, the injector at the rear part of the syringe needle base pierces the rubber plug after medicine liquid is injected and then the rubber plug of the syringe is air-leaked; when used again, since the medicine liquid cannot be pumped due to air leakage of rubber plug, the syringe cannot be used again so as to be auto disable; therefore, the syringe has the characteristics of convenient operation and use, disposable performance and auto disable function after used.
Description
Technical field
This utility model relates to a kind of syringe, it is a kind of after it is injecting medicinal liquid, the Spina jujubae at injecting needle base rear portion makes syringe rubber plug gas leakage after puncturing plug, when reusing once more, because of plug gas leakage can't be aspirated medicinal liquid, thereby syringe can't be reused, reach the self-destruction syringe of self-destruction.
Technical background
Along with promoting the popularization use of disposable use medical supplies, disposable sterilized syringe particularly, in its use and processing procedure subsequently, owing to need artificially it to be carried out conscious processing, be repeatedly used thereby can exist inevitably, can't really realize disposable purpose.In order to overcome the above problems, applied in the self-destruction syringe of patent at present, having adopt to increase metal spring sheet or other auxiliary accessories, can only can not adopt automatization's assembling by artificial assembling, thereby speed of production is slow, and because of increasing auxiliary accessories, production cost is also just high, therefore, should make the syringe damage, can large-scale production reduction manufacturing cost become a great problem again simultaneously.
The utility model content
The purpose of this utility model just is to provide a kind of syringe, it is after injection finishes, the Spina jujubae at injecting needle base rear portion makes syringe rubber plug gas leakage after puncturing plug, when reusing once more, because of plug gas leakage can't be aspirated medicinal liquid, thereby syringe can't be reused, really accomplish disposable use, and easy to operate self-destruction syringe.
This utility model is made up of entry needle, urceolus, plug and core bar, and entry needle is made up of needle shield, needle tubing, needle stand; The anterior joint portion of needle stand for matching with needle shield, the middle part outer wall is provided with an external ear, the external ear rear portion is provided with a cylindrical or conical joint portion, its rear portion is provided with a Spina jujubae that can puncture plug, the front portion of urceolus is provided with a draw-in groove or thread groove, and the taper indent disc that cooperates with needle stand, there is a crimping at the rear portion, the head of core bar is provided with an inner groovy that matches with the needle stand Spina jujubae, the inner outer wall in position of wrapping up in cover at plug is provided with the boss that prevents the plug slippage, simultaneously on its boss, be provided with disappointing groove, be provided with a baffle plate thereafter, be provided with a spacing card on top by hands.When injecting needle base is installed to urceolus, cylindrical or the conical joint portion at needle stand external ear rear portion and the taper indent disc of urceolus front interior cavity closely cooperate, external ear because of the needle stand middle part is stuck in the draw-in groove or thread groove of urceolus simultaneously, entry needle can not be moved forward and backward, thereby guarantee that entry needle and urceolus reach sealing property, can prevent from simultaneously to make plug be punctured loosening simultaneously entry needle at the pushing core bar.
Description of drawings
Fig. 1, Fig. 2 are respectively the structural representation of two kinds of self-destruction syringe embodiment
The specific embodiment
Below in conjunction with embodiment 1 and contrast accompanying drawing this utility model is described in further detail.
Embodiment 1: self-destruction syringe
This utility model is made up of entry needle 1, urceolus 2, plug 3 and push rod 4, and entry needle 1 is made up of needle shield 1-1, needle tubing 1-2, needle stand 1-3; The front portion of needle stand is the joint portion 1-6 with needle shield, the middle part outer wall is provided with an external ear 1-7, external ear can be made as circle or for square angle or be half arc or for spline, the rear portion of needle stand is provided with a batter post 1-4, be provided with a Spina jujubae 1-5 behind the batter post, needle stand inner chamber front portion is the joint portion with needle tubing and bonding agent.Front inner wall at urceolus 2 is provided with the draw-in groove 2-1 that matches with needle stand external ear 1-7; Be provided with in draw-in groove 2-1 rear end one with the taper indent disc 2-2 of needle stand 1 back taper post 1-4 driving fit, can be provided with one at the inner chamber of the end of urceolus and prevent that annular protrusion 2-3 and urceolus 2 rear portions that core bar is pulled out are provided with a crimping 2-4; Be provided with an inner groovy 4-1 who matches with the needle stand Spina jujubae in push rod 4 front portions, be provided with a protruding 4-4 who prevents the rubber piston slippage at the inner outer wall in the position of cover plug 3, at protruding 4-4 rear portion one baffle plate 4-5 is arranged, be provided with by hands 4-3 at the rear portion of push rod 4 and be provided with a spacing card 4-2 in front portion by hands; During assembling, entry needle 1 is inserted urceolus 2 the external ear 1-7 of entry needle is snapped in the draw-in groove 2-2 of urceolus 2, plug 3 cover fruits on core bar 4 forward protruding 4-4, will be inserted in the urceolus 2 with the push rod 4 of plug 3 subsequently.
Before injection, syringe carries out aspiration medicinal liquid, deaeration routinely, subsequently the banking stop 4-2 on the core bar 4 is pressed into to the internal core rod center, can inject.In injection process, only injecting liquid drug need be finished gets final product.After having injected medicinal liquid, because the Spina jujubae 1-5 at needle stand 1-3 rear portion has punctured plug 3, cause gas leakage between plug 3 and the core bar 4, when wanting once more to use this syringe to pull back core bar 4 drawing liquids,, gas leakage can't reuse because of making syringe not take out medicinal liquid.
Embodiment 2: self-destruction syringe
This utility model is made up of entry needle 1, urceolus 2, plug 3 push rods 4 and sealing ring 5, sealing ring 5 is installed in the rear portion of entry needle external ear, play and prevent because of closely not leaking between needle stand 1-3 and the urceolus 2, present embodiment 2 is equally installed the entry needle 1 that installs sealing ring 5 with embodiment 1 with embodiment 1 different being, can equally use with embodiment 1.
