Abstract

The utility model relates to a syringe needle. A hollow needle body is fixed on a needle handle, and the top end of the needle body is a solid needle tip. A front-end pipe wall is drilled with a plurality of through holes which are distributed evenly, so that the condition that the fragments of a medicine bottle stopper are often brought into an infusion medicine when a usual needle with an inclined end-face is in infusion medicine preparing is avoided, and the phenomenon of infusion reaction of a patient caused by the fragments of the bottle stopper is basically eliminated.

Description

A kind of syringe needle

Technical field this utility model relates to a kind of syringe needle, belongs to technical field of medical instruments.

The syringe needle majority that background technology is used at present is the facial needle point of splay end, the facial needle point of splay end cuts into the fragment of aperture size with the little bottle plug of powder charge product easily and brings in the injection in configuration infusion medicine process, aseptic requirement as the venous transfusion strictness, this phenomenon never allows, and also truly has the bottle stopper fragment to bring the case that infusion reaction takes place in the transfusion into through clinical observation.

The summary of the invention the purpose of this utility model provides a kind of syringe needle, makes it when the preparation transfusion, and syringe needle can not be brought fragment under the bottle stopper cutting in the transfusion into.This purpose realizes in the following manner: this syringe needle is made of needle handle 1, needle body 2, needle point 3 etc., the needle body of hollow is fixed on the needle handle, solid needle point is made on the top of needle body, and the front end tube wall of needle body is drilled with some through holes 4 and is evenly distributed, and medicinal liquid is flowed smoothly.

Adopt this utility model, when the preparation infusion medicine, bottle stopper has reduced the probability of secondary pollution with regard to not cut into fragment by needle point and bringing in the transfusion.Because there are a plurality of holes needle body front end side, total through-current capacity is greater than the facial pin hole flow of splay end, and infusion speeds up.

The specific embodiment

A kind of syringe needle is made of needle handle 1, needle body 2, needle point 3 etc., and needle body 2 is fixed on the needle handle 1 for hollow pipe, and solid needle point 3 is made on the top of needle body 2, and its front end tube wall is drilled with some through holes 4 and is evenly distributed.In implementation process, needle body, needle point are that stainless steel pipe is made, and needle handle can be an injected plastics material, by glue it is bonded together.

Claims (1)

1. syringe needle, by needle handle (1), needle body (2), needle point formations such as (3), needle body (2) is characterized in that for hollow pipe is fixed on the needle handle (1): solid needle point (3) is made on the top of needle body (2), and the front end tube wall of needle body (2) is drilled with some through holes (4) and is evenly distributed.
