Abstract

The utility model is medical syringe needle with two holes, which is injection or dispensing pinhead used for human body muscle, internal organs, blood vessel. The utility model comprises a pinhead seat, a pinhead stick, a needle tip, the needle tip shows metuliform, the inside is hollow, the cones of the two sides of the needle tip are provided with a pin hole respectively, both of the two pin holes are communicated with the pinhead stick cavity. The utility model has following advantages: when the model punctures patient, pain is little. Physic liquor disperses quickly in intramuscular injection process. the model has little damage for venous vessel wall in the intravenous drip process, avoids liquid leakaging. When prepare physic liquor, the bung can not be cut into shivers that can be carried into physic liquor.

Description

The diplopore syringe needle

Technical field

This utility model relates to medical instruments field, a kind of injection needle 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.

This utility model is achieved in that the diplopore syringe needle, constitute by needle point, needle shaft, needle stand, needle point be taper, in be hollow, respectively be provided with a pin hole on the conical surface of both sides, pin hole communicates with the needle shaft inner chamber one by one by needle point is hollow.

The beneficial effects of the utility model are: its puncture during patient pain light, during intramuscular injection the medicinal liquid disperse fast, during intravenous drip, damage to the venous blood tube wall is few, avoid fluid seepage, when preparating liquid, bottle stopper can not cut into fragment by needle point and bring in the medicinal liquid.

Description of drawings

Fig. 1 be this utility model embodiment partly cut open front view.

Fig. 2 is the local right view that amplifies in A district among Fig. 1.

Among the figure, 1. needle stand, 2. needle shaft, 3. needle point, 4. pin hole, 5. needle shaft inner chamber.

The specific embodiment

The utility model is described in further detail for the contrast accompanying drawing below.

The diplopore syringe needle is made of needle point (3), needle shaft (2), needle stand (1), needle point (3) be taper, in be hollow, respectively be provided with a pin hole (4) on the conical surface of both sides, pin hole (4) communicates with needle shaft inner chamber (5) one by one by needle point is hollow.During injection, transfusion arrives the needle point place by needle shaft inner chamber (5) and produces eddy current, flows out the intravasation chamber by the pin hole on the conical surface of needle point both sides.

The injection needle needle point is sharp keen, and it is not eccentric to be taper, and pain is light when the puncture patient, in the inserting needle process, does not produce the direction skew, can reduce the 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.

Claims

1. the diplopore syringe needle is made of needle point, needle shaft, needle stand, it is characterized in that: needle point be taper, in be hollow, respectively be provided with a pin hole on the conical surface of both sides, pin hole communicates with the needle shaft inner chamber one by one by needle point is hollow.
