Description

A kind of syringe

This utility model belongs to a kind of medication injections apparatus.

At present, the medical syringe of selling and using clinically all is when patient need inject on the market, just will give patient injection behind medicine or the medicinal liquid suction syringe.Like this when running into the emergency case patient, as: adrenaline tartrate is the most frequently used in the shock treatment, one of the most urgently needed first-aid medicine, and the irritated patient's shock symptom of medicines such as penicillin breaks with tremendous force, and the critical disease rescue of other cardiac arrests need be injected epinephrine immediately, so routine has an epinephrine and one pair of syringe in the treatment dish of lesion nursing group, when operating, the operator must get ampoule and syringe, break ampule sealing off with the fingers and thumb, take out medicine, then injection, operation link is many like this, waste time, this is very disadvantageous for the emergency case patient that time is life, moreover when breaking ampule sealing off with the fingers and thumb, if make mistakes in anxious, broken accidentally, that makes the matter worse especially, delays rescue.Simultaneously, owing to ampoule usually rolls in dials, rubs, after a period of time, printed words such as " label " printed on the ampoule, " shelf-life " are smudgy, do not know the label and the date of production, the medicine in the ampoule just can not continue to use and have to discard, and causes waste.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and a kind of syringe that directly has medicine in syringe is provided.

The technical solution of the utility model is finished like this: the afterbody of the needle tubing of this syringe protrudes into the cavity central authorities of hollow in the patch plug, it is pointed that the needle tubing afterbody is hollow, the outer garden of the interior garden of hollow and the syringe medicated cap on syringe elasticity interference fit in the patch plug, the front end of syringe has a boss, and boss is interior empty taper, and a syringe medicated cap is arranged on the boss, needle cap also is taper, boss and needle cap resilient engagement have certain spacing between needle handle front end and syringe bottom, inject medicine in the spacing.

The utlity model has following advantage: simple and efficient to handle, can improve rescue service efficient greatly; Disposable combination is convenient to store, is carried, safe, aseptic, is applicable to the treatment in multiple places such as inside and outside and family of institute, saves oneself for clear-headed also available its of patient still; The medicine value preserving phase in the syringe matched with the medicine shelf-life in the ampoule, and explanatory notes such as the date of production, shelf-life directly beat on injector package, and difficult generation rolling friction is difficult for causing that the handwriting is blurred; Medicine in the ampoule directly is infused in the syringe, saves material and expense, and cracky not.

Now further describe embodiment in conjunction with drawing: the afterbody of the needle tubing of this syringe protrudes into the cavity central authorities of hollow in the patch plug, it is pointed that the needle tubing afterbody is hollow, the outer garden of the interior garden of hollow and the syringe medicated cap on syringe elasticity interference fit in the patch plug, the front end of syringe has a boss, and boss is interior empty taper, and a syringe medicated cap is arranged on the boss, needle cap also is taper, boss and needle cap resilient engagement have certain spacing between needle handle front end and syringe bottom, inject medicine in the spacing.Owing on the boss of syringe a syringe medicated cap is arranged, therefore, the medicine in the syringe can not leak outside.

The pointed cone tip shape that can be of this needle tubing afterbody hollow also can be inclined point shape.

When using this syringe, as long as the patch plug on the needle tubing is inserted on the syringe medicated cap, because the needle tubing afterbody protrudes into the cavity central authorities of hollow in the patch plug, and afterbody is that hollow is pointed, therefore just having pierced through syringe medicated cap elasticity interference fit when inserting is fixed on the boss of syringe, can inject as long as then pull up the needle tubing cover, convenient, fast.

Claims (3)

1. syringe, comprise syringe, needle handle, needle tubing, it is characterized in that the afterbody of needle tubing protrudes into the cavity central authorities of hollow in the patch plug, it is pointed that the needle tubing afterbody is hollow, the outer garden of the interior garden of hollow and the syringe medicated cap on syringe elasticity interference fit in the patch plug, the front end of syringe has a boss, and boss is interior empty taper, and a syringe medicated cap is arranged on the boss, needle cap also is taper, boss and needle cap resilient engagement have certain spacing between needle handle front end and syringe bottom, inject medicine in the spacing.
