Abstract

The dispensing needle, relating to a medical appliance, to be specific, relating to an injection and transfusion needle. The purpose of the utility model is to change the shape of the injection and transfusion needle. The technical proposal to be realized is that the existing tube shape needle body with a needle is reserved, the improvement is that the needle tip is made in a hollow conoid shape, a plurality of medical fluid holes are arranged on the transitional part from the conoid lower part and the conoid to the tube shape needle body, and the hole shape has two types-a seam type and a circular type. The needle can enable the medical fluid to pervade to human muscles and blood vessels of larger area, and the fluid is not injected out from the needle tip, thereby reducing the impact to human muscles and blood vessels and reducing human injury and pain. Glass chippings larger than the medical fluid hole can't enter the human body.

Description

Disperse pin

Technical field: this utility model relates to a kind of medical apparatus and instruments, relates in particular to the pin of a kind of injection and transfusion usefulness.

Background technology: the injection used of our hospital that sees at present and the pin of transfusion usefulness are by a hollow metal tube, gos into the inclined-plane pointedly from cutting with the acutangulate angle of its axis inclined-plane, and the inclined-plane is very sharp on every side.When injection and transfusion, beveled tip is thrust human body, and human body has been subjected to the cutting on inclined-plane, causes needle track place skin, muscle, blood vessel to be cut brokenly, taking out pin later on can not be closed well, therefore produce hemorrhage many, local hematoma, the pinprick medicinal liquid that exosmoses, in addition, when pushing away medicinal liquid, be that a straight hole enters, increased the pressure of local organization, tissue obviously easily takes place and hardens and abscess in the pain reflection.Also have, less than the chips of glass of pin internal diameter have enter human body may, work the mischief.

Summary of the invention: the purpose of this utility model is to change injection and the type shape of the syringe needle of the pin of the usefulness of infusing, to overcome existing above-mentioned technical deficiency.Realize that the technical solution of the utility model is the tubulose needle body that keeps existing syringe needle, improved is that needle point is made hollow taper shape, is that curve and the sewing needle commonly used now that seamlessly transits has same profile in conical lower section and tubulose needle body coupling part.To the part of tubulose needle body transition a plurality of medicinal liquids hole is arranged in conical lower part and taper shape, the shape in hole has two kinds, and the one, the seam type, the 2nd, circular.

This utility model beneficial effect is: in injection and when transfusion,, what thrust human body is conical needle point, and taking out can be closed well after the pin, has reduced hemorrhage, local hematoma, the pinprick medicinal liquid that exosmoses.This pin can make pharmaceutical liquid be penetrated into people's muscle and blood vessel from bigger area, and liquid is not penetrated from needle point, reduces the impact of liquid to people's muscle and blood vessel, reduces injury and misery that the people is subjected to.Chips of glass greater than medicine administered by injection liquid hole can not enter human body.

Description of drawings:

Fig. 1 is needlepoint form figure of the present utility model, and the medicinal liquid hole is a seam shape 3.

The enlarged drawing in the medicinal liquid hole 3 of the seam shape that Fig. 2 is, two ends are semicircle 4.

Fig. 3 is needlepoint form figure of the present utility model.

Fig. 4 is the enlarged drawing in Fig. 3 medicinal liquid hole 5, and medicinal liquid hole 5 is circular.

The specific embodiment:

Embodiment one: see Fig. 1, design hollow taper shape 1 and make syringe needle that get a plurality of medicinal liquids hole 3 in conical lower part and taper shape to the part of tubulose needle body 2 transition, the shape in hole is a seam shape 3, the slit-like hole that present embodiment is beaten is 10.

Embodiment two: see Fig. 3, design hollow taper shape and make syringe needle that get a plurality of medicinal liquids hole 5 in conical lower part and taper shape to the part of tubulose needle body transition, the shape in hole is circular, the circular hole that present embodiment is beaten is 14.

Claims

1 disperses pin, is made up of needle stand, needle tubing and needle point, it is characterized in that needle point is hollow taper shape (1), and conical (1) and needle tubing (2) coupling part are the curves that seamlessly transits and have the medicinal liquid hole.

2 according to the described dispersion pin of claim 1, and the shape that it is characterized in that the medicinal liquid hole is a seam shape (3), and the two ends of seam shape (3) are semicircle (4).

3 according to the described dispersion pin of claim 1, and the shape that it is characterized in that the medicinal liquid hole is circular (5).
