Description
Technical field
The invention belongs to manufacture technology field of medical appliance, is related to a kind of syringe, it is related specifically to a kind of with draw-in groove
Insertion self-destruction type syringe.
Background technology
Either in developed country still in less developed country, syringe obtains pole as a kind of basic medical treatment equipment
It is widely applied.Syringe is made up of the foraminate syringe of front end band and matching piston core bar, is extracted in core bar
When liquid or gas suck from syringe front end aperture, liquid or gas are extruded when core bar is pushed.
Conventional syringe, can be with Reusability for feature, but the syringe needle (3) of syringe needs to pierce through human body skin
Skin simultaneously contacts blood, must change when injecting again every time；The medicinal liquid that simultaneously caused due to use inside syringe 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 is some self-destructive syringes, but generally complex structure, cost is very high.
Therefore, it is necessary to improved technical scheme is provided, to overcome technical problem present in prior art.
Content of the invention
It is an object of the invention to provide the low self-destructive syringe of a kind of simple structure, cost.
In order to achieve the above object, the invention provides a kind of with draw-in groove insertion self-destruction type syringe, including one
Syringe body, the syringe body include empty cylinder, piston body and syringe needle；The empty cylinder includes that inside includes medicinal liquid cavity
Cylindrical peripheral wall, is closed with cover plate, the other end positioned at described cylindrical peripheral wall one end and offers be connected with the medicinal liquid cavity logical
Hole, the empty cylinder also include a nipple, the nipple be fixedly installed on the cover plate away from the medicinal liquid cavity side；It is located at
Liquid outlet is provided with the cover plate, the nipple is arranged at the liquid outlet；The piston body includes being connected with each other successively
Piston pressing plate, piston shaft and piston handle, it is empty that the piston pressing plate inserts the medicinal liquid with the piston shaft by the through hole
Intracavity portion, the sliding fit inside of the perisporium of piston pressing plate and the cylindrical peripheral wall；The syringe needle includes pintle, pin stalk and pin
Point, the pintle are socketed on the nipple；Medicinal liquid cavity side is provided with a thimble positioned at the cover plate, positioned at described
Hook is provided with back on thimble, and the thimble position is provided with draw-in groove positioned at the piston pressing plate.
During preparation, insert the needle in the middle of medicinal liquid, lift piston will medicinal liquid suction sky cylinder medicinal liquid cavity in, then need into
It is about to the action that gas is discharged from medicinal liquid cavity, by syringe towards vertically, promotion piston makes air just be completely exhausted out medicine
Liquid air chamber.
During injection, to one lateral movement of cover plate, with continuing deeper into for piston pressing plate, thimble is pierced into piston pressing plate to piston pressing plate
On draw-in groove in, due to being provided with back hook, cause thimble extract from draw-in groove, so as to reach the purpose of self-destruction.
Preferably, the thimble is arranged at the cover plate central, and the draw-in groove is arranged on the center of the piston pressing plate
Place.As piston can be rotated around own central axis, if thimble and draw-in groove are designed in off-centered position, it is likely that cause
The situation of misalignment occurs, and causes when operator is injected using syringe, and thimble contacts its that have draw-in groove at cover plate
His position, and cause piston continue deeper into, so as to interrupting action of injection；When using such scheme, no matter piston is such as
What rotates, and can make to be on same line of motion all the time between thimble and draw-in groove, the piercing action of thimble is smoothly entered
OK.
Preferably, the liquid outlet includes that liquid outlet, medicine liquid channel and liquid inlet, the medicine liquid channel are located at the cover plate
Inside, the liquid inlet are arranged on around the thimble, and the liquid inlet is connected with the liquid outlet by medicine liquid channel.Push away
During piston, the medicinal liquid in medicinal liquid cavity can pass sequentially through liquid inlet, medicine liquid channel and liquid outlet and reach nipple, and then from syringe needle
Outside exhaustjet device.It is highly preferred that the liquid inlet includes that 2 ~ 8 enter liquid circular hole.Can will enter liquid circular hole to be designed around
Thimble arrangement, makes more regular in structure, reduction manufacture difficulty.
Preferably, the liquid outlet is arranged on the centre of the cover plate.It is also preferable that the liquid outlet is arranged on
The off-center position of the cover plate.The design attitude of liquid outlet directly determines the position of nipple.When such as sky cylinder internal diameter is less, will
Nipple is arranged on cover plate central position and is conducive to production and manufacture, and when empty cylinder internal diameter is larger, nipple is arranged on cover plate inclined
Contribute to injection from center to use.
Preferably, the piston pressing plate and piston shaft, and piston shaft and piston handle, are fixed by binding agent.Equally
Preferably, the piston pressing plate, piston shaft and piston handle are integrally formed.
It is preferably located on the draw-in groove and is provided with waterproof epiphragma.Be so designed that, it is ensured that thimble be pierced into draw-in groove it
Before, enter inside draw-in groove without medicinal liquid.
Compared with prior art, the beneficial effects of the present invention is：Simple structure, cheap, self-destruction effect is good, can have
Effect prevents recycling for syringe.
