CN2301215Y - Improved syringe needle - Google Patents

Abstract

The utility model discloses an improved syringe needle. A hollow needle body is fixed on a needle handle, the top end of the needle body is a solid needle tip, and a plurality of through holes which are uniform distributed are drilled on the tube wall of the front end. Thereby, the situation that the broken blocks of medicine bottle stoppers (rubber sticks) are always carried in infusion medicine when the usually used needles of oblique end surfaces prepare infusion medicine is avoided, and the phenomenon that the infusion reaction of patients, which is caused by the broken blocks of the medicine bottle stoppers is fundamentally prevented from occurring.

Description

A kind of improved syringe needle

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

At present, the syringe needle that hospital clinical uses is the facial needle point of splay end, particularly the syringe needle of 20ml syringe mostly is to use for the preparation infusion medicine, the facial needle point of splay end often cuts into the little bottle plug of powder charge product the fragment (glue rod) of aperture size and brings in the drip liquid in process for preparation, antibiotic transfusion for heavy dose is prepared along with the antibiotic bottle number increases, and probability and quantity that the glue rod enters in the infusion medicine just increase.As the aseptic requirement of venous transfusion strictness, this phenomenon is unallowed, really finds also that through clinical observation the patient infusion reaction occurs and sneaks into relevant case with the glue rod.

The purpose of this utility model will provide a kind of improved syringe needle exactly, makes it when joining transfusion, and syringe needle can not be brought fragment under the bottle stopper cutting in the transfusion into.

For achieving the above object, form this utility model by needle handle, needle body, needle point etc., wherein the needle body of hollow is fixed on the needle handle, and solid needle point is made on the top of needle body, and the some through holes of its front end wall uniform distribution flow smoothly for medicinal liquid.

Adopt this utility model, when the preparation infusion medicine, bottle stopper just can not cut into fragment (glue rod) by needle point and bring in the transfusion, has reduced the probability of secondary pollution.Stopped to sneak into patient's infusion reaction situation that transfusion occurs because of the glue rod.Because a plurality of holes are beaten in needle body front end side, total circulation is greater than the facial pin hole flow of splay end, speeds up so infusion makes up a prescription.

Fig. 1 is this utility model structure principle chart.

Further narrate this utility model below in conjunction with accompanying drawing:

With reference to Fig. 1, this utility model is made of needle handle 1, needle body 2, needle point 3 etc., and wherein 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 injected plastics material, by glue it is bonded together.

Claims (1)

1. improved syringe needle, by needle handle (1), needle body (2), needle point formations such as (3), needle body (2) is fixed on the needle handle (1) for hollow pipe, it is characterized in that; Solid needle point (3) is made on the top of needle body (2), and if the front end tube wall of needle body (2) is drilled with in through hole (4) and be all and distribute.
