Abstract
The utility model relates to a disposable aseptic injector which is composed of a needle, a needle rubber piston, and a piston rod. A projecting portion according to the sizes of internal diameters of needle tube nipples is arranged at the front end of the rubber piston, no medicine liquid is left in the nipple during the injection, the curative effect of the medicine is ensured, and the medicine liquid wasting is avoided. The utility model is an obvious improvement of existing injectors, and is suitable for the medical departments.
Description
This utility model belongs to medical instruments field, is specifically related to a kind of modified model disposable sterilized injector.
Syringe is the requisite medical apparatus of medical department, clinically injectable drugs that are used for more, medical department adopts commercially available disposable sterilized injector at present, and is simple in structure, easy to use, have wide range of applications and consumption very big.But Clinical Practice shows: when using the injector to inject medicine, because the nipple interior (outside is with that part of of syringe needle) of needle tubing front end is not stretched in the rubber piston front portion, so there is medicinal liquid residual.This part residual liquor is about 0.05 milliliter, as diluting 800,000 unit penicillins by 2 milliliters of solvents, then has 20,000 unit penicillins not inject in the patient body approximately, thereby influences curative effect of medication, and the child is because of injecting dose according to the weight, and then influence more very.And cause drug waste.
The purpose of this utility model provides a kind of disposable sterilized injector that does not stay residual liquid, medicine was injected fully guaranteed curative effect in patient's body, avoids waste again.
The purpose of this utility model is to realize like this, press needle tubing front end nipple internal diameter size in the rubber piston front portion of syringe and increase by a projection, during injectable drug, piston rod is pushed ahead this projection is stretched in the nipple of needle tubing front end, make it not interspace, medicine is injected in patient's body fully.
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1: be this utility model disposable sterilized injector sketch map.
Syringe needle 1 is enclosed within on the front end nipple 2 of needle tubing 3 among Fig. 1, and when syringe was inhaled medicinal liquid, piston rod 5 drove piston 4 and pulls out the suction medicinal liquid, holds up push piston bar 5 to discharge gas needle tubing.During injection syringe needle 1 is penetrated in patient's body, push piston bar 5 stretches in the front end nipple 2 of needle tubing 3 projection of rubber piston 4, thereby reaches in the needle tubing the not purpose of residual liquor.
Dosage was accurate when this utility model made injectable drug, avoided liquid waste, guaranteed curative effect of medication, and simple in structure, easy to use, was suitable for generally using at medical department.
