Description

Medicine administered by injection integral type vaccination disposable syringe

Technical field

This utility model relates to a kind of vaccine syringe, the vaccination of medicine administered by injection integral type specifically disposable syringe.Be applicable to all kinds of vaccinoprophylaxis.

Background technology

The existing employed disposable syringe of vaccination is the medicine administered by injection divergence type, and different models such as 1ml, 2ml, 5ml are arranged, the shortcoming of this vaccine syringe is: the one, and medicine administered by injection separates, when the vaccine aerofluxus is extracted in each inoculation, all can cause the loss of vaccine, the vaccine utilization rate is low; The 2nd, after the vaccination, syringe easily is recovered utilization, causes iatrogenic pollution; The 3rd, the many usefulness of an easy pin are promptly reused; The 4th, repeat to extract vaccine easily, cause mistake and accident.

Summary of the invention

Technical problem to be solved in the utility model is: the medicine administered by injection one, one people, one pin, disposable use, no vaccine loss, and can not reclaim again and utilize, avoid iatrogenic pollution, prevent the mistake and accident reusing, repeat to extract, reach the medicine administered by injection integral type vaccination disposable syringe of a people one medicine one pin.

For solving above technical problem, the technical scheme that this utility model adopted is: this medicine administered by injection integral type vaccination disposable syringe, by puncture needle, the pin medicated cap, needle stand, syringe, piston, piston handle constitutes, syringe and needle stand once are injected into a whole, the front end of syringe inner chamber is storage vaccine chamber, establishes envelope medicine mouth on the wall in storage vaccine chamber, behind the disposable injection medicine, mouth is shut, set up defences from the push-and-pull back-up ring between cylinder seat and the piston handle seat, make that piston handle can not push away when not injecting, can not draw, the needle stand center is a cone cavity, the point of cone cavity is established stop-return slot, and establish and the corresponding to cone of cone cavity at the center on the piston nose face, and the elasticity stopper is established at the cone tip, make injected after, piston and needle stand are fixed, and piston can not be pulled out again, and syringe needle can not be pulled up, reach whole pin one, can not be recycled.This utility model is also implemented by following measure: storage antetheca vaccine medicine liquid outlet place, vaccine chamber establishes the envelope film, in case vaccine enters in the needle stand in advance, also seal simultaneously, storage vaccine intracavity storage vaccine dose is the dosage according to used vaccine regulation injection one people, different vaccines has different dosage, as for bacillus calmette-guerin vaccine, the storage dose is 0.1ml; Anti-consistent with the cylinder seat profile from push-and-pull back-up ring profile, be generally ellipse, the center is a circular hole, Circularhole diameter is consistent with the syringe internal diameter, symmetricly in circular hole establish two lance tooths, on push-and-pull back-up ring front, also establish barb anti-, on piston handle, establish draw-in groove, establish the barb hanging hole on cylinder seat, when not injecting, anti-lance tooth on the push-and-pull back-up ring is stuck in the draw-in groove of piston handle, barb hangs in the barb hanging hole on the syringe handle, at this moment, piston handle can not promote forward, can not outwards pull out; When the length of the cone on the piston nose face was shifted the end onto with piston, when promptly having injected, the elasticity stopper at cone tip can snap in the stop-return slot at cone cavity tip and be advisable, stopper is an elasticity, when passing the cone cavity front aperture, collapsible, can stretch out after entering stop-return slot; On the syringe outer wall, can indicate vaccine title, dosage, be suitable for the age.When using this utility model, pull up the pin medicated cap, rotate anti-from the push-and-pull back-up ring, make anti-after the push-and-pull back-up ring can slide along piston handle, can directly inoculate, after the vaccine medicinal liquid had pushed away, the cone of piston nose snapped in the cone cavity of needle stand, this moment, the vaccine medicinal liquid all pushed away, the elasticity stopper snaps in the stop-return slot after shifting the end onto, and at this moment, syringe needle, syringe, piston handle all are fixed as an integral body, each parts is all torn open not opened, thus reached this entry needle can only a people, a medicine, a pin, disposable application.

The beneficial effects of the utility model are: compare with the vaccine injection pin of present application, reach a people, a pin, a medicine, disposable application, improved inoculation efficient, stopped the vaccine waste, prevented iatrogenic pollution, avoided repeating extracting, the generation of reusable mistake and accident.
