Abstract
A medical syringe needle head having double holes of the utility model relates to the field of medical apparatus and instruments. The utility model is used for injections of human body muscles, internal organs, and blood vessels, or a physic confecting needle head. The utility model is provided with a subuliform needle point, and the inside is a hollow shape; both sides of the hollow are provided with two needle point holes, and needle point is downwards connected with a needle head neck, a needle head bar, and a needle head handle in turn; the needle point neck is thinner than the outer diameter of the needle head bar and narrower than the inner diameter of the needle head bar, and a ratio of the inner diameter of a needle head neck tube to the inner diameter of a needle head bar tube is 7/10 to 9/10. The utility model has the following advantages: a patient has light ache when a doctor uses the utility model to puncture; the physic liquor can disperse fast when the doctor proceeds muscle injection to the patient; the utility model has few injuries to the vein blood vessel wall during proceeding vein drop, and the liquid can be avoided to leak; the bottle stopper can not be cut into pieces by the needle point and carried in the physic liquor during confecting the physic liquor.
Description
Technical field
This utility model relates to medical instruments field, the injection needle of a kind of usefulness that punctures of more specifically saying so.
Background technology
The injection of the current human muscle of being used for, arteriovenous, internal organs or make up a prescription syringe needle and needle point all are eccentric tooth shape needle tip mostly, and during puncture, because needle tip is roomy, patient's pain is serious.To the intramuscular injection medicine time, medicinal liquid is confined to the needle point front portion, and is little with the human body contact area, disperse is slow.To venous transfusion the time,, cause liquid leakage because needle tip off-centre easily causes the damage to the venous blood tube wall.When preparating liquid, needle point penetrates bottle stopper, and bottle stopper is cut into fragment by needle point and brings in the medicinal liquid, causes secondary pollution.
Summary of the invention
The purpose of this utility model provides a kind of injection needle that is used for human body, and it is had the following advantages: the injection needle needle point is sharp keen, and it is not eccentric to be taper, pain is light when the puncture patient, in the inserting needle process, do not produce the direction skew, can reduce damage to tissue.One small gap is arranged between needle point and the wall of vein when intravenous drip, under the impact of liquid, can strengthen the distance between needle point and the vein tube wall, reduce damage, prevent fluid seepage the vein tube wall.When preparating liquid, needle point penetrates bottle stopper, and bottle stopper can not cut into fragment by needle point and bring in the medicinal liquid, avoids secondary pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail for the contrast accompanying drawing below.
1 is needle point among the figure, needle point be taper, in be hollow, there are two needle point holes 5 both sides, link to each other with syringe needle neck 2, needle shaft 3, pinhead handle 4 one by one downwards, syringe needle neck tube 6 is narrower than syringe needle rod tube 7, its internal diameter ratio is 7/10 to 9/10.Flow velocity is accelerated when liquid passes through syringe needle neck tube 6, produces eddy current at the needle point hollow position, then by needle point hole 5 disperse around needle point.
Claims (2)
1. two syringe needle that portals, constitute by needle point (1), syringe needle neck (2), needle shaft (3), pinhead handle (4), it is characterized in that: needle point (1) be taper, in be hollow, both sides are provided with two needle point holes (5), and needle point hole (5) communicate with syringe needle neck tube (6), syringe needle rod tube (7), pinhead handle (4) one by one by needle point is hollow.
2. two syringe needle that portals according to claim 1, it is characterized in that: syringe needle neck tube (6) is narrow than syringe needle rod tube (7) internal diameter, and syringe needle neck tube (6) is 7/10 to 9/10 with syringe needle rod tube (7) internal diameter ratio.
