Abstract
The utility model relates to a painless needle comprises a needle tail (1), a hollow needle tube (2) and a tip (5). The painless needle is characterized in that a drug opening (4) is arranged at the joint of the cylindrical needle tube (2) and the conical tip (5). For the painless needle maintains an entire tip, the muscle damage can be reduced during injecting; meanwhile, a plurality of drug outlets are arranged to spread the pressure of drug liquid on muscle or blood vessels to lighten the filling of pain, thereby achieving the purpose of reducing the filling of pain.
Description
Technical field:
This utility model relates to a kind of injection tool, relates in particular to a kind of injection Painless syringe needle.
Background technology:
As everyone knows, present widely used injection needle can be divided into stitch, hollow needle tube, needle point three parts from structure, needle point all adopts the cylinder bevel to form, its medicine outlet goes to part back for the cylinder bevel and forms ellipse, but this needle point exists certain damage to the muscle of human body, cause the pain on the human nerve, simultaneously because folk prescription, also exists the defectives such as distending pain sense to human vein or muscle generation pressure inequality to the output medicinal liquid.
The utility model content:
The purpose of this utility model is to provide a kind of Painless syringe needle that reduces the human muscle damages and the output medicinal liquid is evenly distributed.Concrete technical scheme is: Painless syringe needle comprises backshank, hollow needle tube, needle point composition, and cylindrical needle tubing and conical syringe needle joint portion are provided with medicine outlet.
Medicinal liquid is to muscle or venous pressure when injecting for uniform distribution, and the joint portion of needle tubing and needle point can be designed to a plurality of medicine outlets along annular.
Medicine outlet is circular.
Medicine outlet also can be designed to ellipse.
When using Painless syringe needle of the present utility model, backshank is put syringe or is installed on the transfusion device and can normally use.
From the technical solution of the utility model as can be seen, because Painless syringe needle has kept complete tip portion, damage to muscle during injection can be reduced, simultaneously because the setting of a plurality of medicine outlets makes medicinal liquid be dispersed to the muscle of human body or the pressure of blood vessel, alleviate the distending pain sensation, reached the purpose that reduces pain.
Description of drawings:
Fig. 1 is the cutaway view of this utility model Painless syringe needle.
The specific embodiment:
Embodiment 1: design a hollow shape cylinder needle tubing 2, the one end is a backshank 1, and the other end is a cone tip 5, in needle tubing 2 and needle point 5 transition joint portion annular spread medicine outlet 4 is arranged, and present embodiment medicine outlet 4 is selected 2 for use, and medicine outlet 4 communicates with loading hole 3.
Embodiment 2: design a hollow shape cylinder needle tubing 2, the one end is a backshank 1, and the other end is a cone tip 5, is medicine outlet 4 at needle tubing 2 with needle point 5 transition joint portion annular spread, and present embodiment medicine outlet number is selected 3 for use, and medicine outlet 4 communicates with loading hole 3.
