Description

The dispenser in needle tubing skew back hole

Technical field

This utility model relates to a kind of dispenser of needle tubing skew back hole of having improved, and belongs to technical field of medical instruments.

Background technology

The employed dispenser of units such as present domestic hospital roughly has two kinds, and a kind of needle tubing is the inclined-plane pin; Another kind of needle tubing is the side opening pin.Its shortcoming is: 1, pin bottle stopper microgranule in piercing process in inclined-plane falls into medicinal liquid easily; 2, the side opening pin has certain distance because of side opening and needle point, causes medicinal liquid residual when making up a prescription.

Summary of the invention

At the deficiency that present domestic employed disposable use dispenser exists, the purpose of this utility model provide a kind of when neither having puncture the bottle stopper powder come off, can reduce the dispenser in the residual needle tubing skew back hole of medicinal liquid again.

For realizing above purpose, take following technical proposal, needle tubing one end of the dispenser in needle tubing skew back hole is made cone, needle point is sharp, and the medicinal liquid manhole appendix is opened at needle tubing nose-circle cone inclined-plane and needle tubing cylinder intersection, blunt mouthful of its edge.

Owing to adopt technique scheme, when puncture, do not pollute medicinal liquid, and reduced the medicinal liquid residual quantity because the blunt mouth in the edge in hole can not make bottle stopper produce exfoliation.
