Description
Technical field
The invention belongs to manufacture technology field of medical appliance, be related to a kind of syringe, be related specifically to one kind puncture formula insert
Enter the syringe of self-destruction type.
Background technology
Either in developed country still in less developed country, syringe, as a kind of basic medical treatment equipment, all obtains pole
It is widely applied.Syringe is made up of the foraminate syringe of front end band and matching piston core bar, extracts in core bar
When liquid or gas suck from syringe front end aperture, when core bar pushes, liquid or gas are extruded.
Conventional syringe, can be with Reusability for feature, but the injection needle of syringe needs to pierce through human body skin
Skin simultaneously contacts blood, must change when again injecting every time；Simultaneously inside syringe due to using and the medicinal liquid that causes and thin
Bacterium pollutes, and can make syringe each time using being front required to carry out thoroughly cleaning and sterilization.
According to investigation, the infection of some diseases, there is direct sexual intercourse with the Reusability of syringe.
In the middle of prior art, there are some self-destructive syringes, but usual complex structure, cost is very high.
Therefore, it is necessary to provide improved technical scheme, to overcome technical problem present in prior art.
Content of the invention
It is an object of the invention to provide the self-destructive syringe that a kind of structure is simple, cost is low.
In order to achieve the above object, the invention provides a kind of puncture the syringe that formula inserts self-destruction type, carry including one
The liquid medicine injection shooting cylinder of nipple, pusher body and injection needle；Described liquid medicine injection shooting cylinder includes cylindrical peripheral wall and is sealed on described cylinder week
The top cover of wall one end, described top cover includes medial surface towards described cylindrical peripheral wall side and dorsad described cylindrical peripheral wall side
Lateral surface, described nipple is arranged on described lateral surface, is provided with puncture needle body on described medial surface；Described pusher body
Including one carry fragile penetration push liquid sheet, be fixed in described push liquid sheet with described cylindrical peripheral wall inwall gap cooperation
Fluid push rod and be fixed on and push away liquid handle on described fluid push rod, described push liquid sheet with described push away that liquid handle is fixed on described fluid push rod two
End；Described fragile penetration is corresponding with described puncture needle body position；Described injection needle includes pintle, pin stalk and needle point, described pin
Bolt is socketed on described nipple.
Injection needle and nipple constitute the outside passage with liquid medicine injection shooting cylinder inner space, liquid medicine injection shooting cylinder inner space master
To be made up of cylindrical peripheral wall and top cover, to form the staving of an approximate upper end open, the bottom of staving is top cover, punctures needle body
Effect is to puncture the fragile penetration in push liquid sheet.During use, first injection needle is goed deep in the middle of medicinal liquid, lift push rod
Body, now due to air pressure, medicinal liquid is drawn into the inner space of liquid medicine injection shooting cylinder, then proceeds by action of injection, when promotion pushes away
During the body of rod, push away the handgrip part that liquid handle is operator, push away the top cover motion in the same direction of liquid handle, fluid push rod and push liquid sheet one, and with
Motion, medicinal liquid is from nipple is through injection needle gradually exhaustjet device.With the continuation campaign of push liquid sheet, three kinds of shapes can be formed
State, the first state be push liquid sheet away from top cover and gradually close to it, second state be push liquid sheet just with puncture needle body
Joint, the third state is punctured needle body for push liquid sheet and pierces through, and its pierced position is in fragile penetration.With above-mentioned three
The conversion of kind of state, final push liquid sheet is touched with top cover, medicinal liquid by whole exhaustjet devices outside, complete action of injection.When being in
During the third state, fragile penetration through part is punctured needle body and just blocks, and medicinal liquid will not be from the internal warp of liquid medicine injection shooting cylinder
Through part spills, and therefore first time injection can be normally carried out, but when being intended to carry out second injection, with pulling pusher body, pushes away
Liquid plate departs from puncturing needle body, and the medicinal liquid being extracted in liquid medicine injection shooting cylinder can spill outside syringe with running through position.
The fragile penetration quantity being preferably located at setting in described push liquid sheet is multiple, and rounded arrangement.More preferably
Ground, the multiple fragile penetration of described rounded arrangement is evenly arranged.Even more preferably, the quantity of described fragile penetration
For 2 ~ 8.It is so designed that, operator can be made to be directed at fragile penetration easily and puncture needle body.
Preferably, described nipple is located at the centre in outside of top cover face.When the diameter of liquid medicine injection shooting cylinder is less, nipple
It is arranged on the centre in outside of top cover face, structural integrity can be effectively improved, reduce manufacture difficulty, easy operation.Equally
Preferably, described nipple is located at the off-center position in outside of top cover face.When liquid medicine injection shooting cylinder is when being relatively large in diameter, nipple is arranged
At the off-center position in outside of top cover face, can conveniently inject, make injection needle easily parallel with human vas.
Preferably, described push liquid sheet and fluid push rod, and fluid push rod with push away liquid handle, all fixed by binding agent.Equally excellent
Selection of land, described push liquid sheet, fluid push rod and push away liquid handle and be integrally formed.
Compared with prior art, the beneficial effects of the present invention is：Structure is simple, and cheap, self-destruction effect is good, can have
Effect prevents recycling of syringe.
