Abstract

The utility model relates to a medical syringe needle. A plurality of pores are arranged near the horseshoe-shaped needle orifice of an ordinary needle, the pores are respectively arranged at different cross-sections and are relatively concentrated at the needle part, the injected medicine liquid is jetted, is injected into muscle through different pores at different directions, the single positional pressure and the chemical stimulation are decreased, the pains are decreased, and the absorption is promoted. The utility model is convenient for the clinical required washing disinfection, and can make the body fluid sampling by puncturing more accurate and rapid, and thus the multiple hole and way type syringe needle can be easily accepted and used by patients and medical members.

Description

Multiple hole and way type syringe needle

This utility model relates to a kind of syringe needle of injector for medical purpose.

Syringe needle all is that one " shape of a hoof " pin mouth is arranged at its needle point place at present, human body is difficult to absorb during this syringe intramuscular injection, easily form enclosed mass, produce pain, this is because the medicine of syringe single direction pushes, cause the pressure of injection site to increase suddenly and single direction, the medicinal liquid stimulation of high concentration causes, and this class syringe needle extracts hydrothorax in puncture, ascites, pericardial effusion, cerebrospinal fluid, during bone marrow etc., its " shape of a hoof " pin mouth institute soothing the liver place may not be exactly the hydrops place, often want rotation direction to move needle position, puncture several times can be successful continuously, and success rate is low, bring misery to the patient, bring operational difficulty to medical personnel.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and a kind of porous multi-orientation type injection needle is provided.

Technical solution of the present utility model is to have some apertures on the front end side wall of syringe needle, they communicate with " shape of a hoof " pin hole at needle tip place, some apertures concentrate in 1/3 section of the front end of needle point relatively, some apertures of syringe needle front end all insert human muscular tissue during with the assurance injection, on the syringe needle front end side wall position of some apertures in vertical direction each aperture certain interval (as Fig. 1, among Fig. 1 this utility model to open three apertures with the syringe needle front end be example) is arranged.So both can not weaken the intensity of syringe needle, the liquid level that can make medicinal liquid be injected into different muscle levels again or make the some apertures of syringe needle leading portion contact different levels is convenient to draw, on the syringe needle front end side wall position of some apertures in the horizontal direction in twos the angle α between the aperture and the syringe needle longitudinal axis be not less than 30 ° (as Fig. 2, among Fig. 2 this utility model still to open three apertures with the syringe needle front end be example), thereby realize the polytropism of the some apertures of syringe needle front end.

This utility model is because porous, multidirectional, multi-level, thereby makes liquid medicine injection be spurting to inject intramuscular from different aperture different directions.The pressure and the medicinal liquid that reduce single position stimulate, and reduce pain, promote to absorb; When the puncture extracting bodily fluid, this utility model has increased the chance that contacts with liquid level greatly, make puncture fast, accurately, reduce the patient suffering, when anesthesia, can make the level of anesthesia and scope more extensive, when doing local block therapy, can significantly reduce puncture time, make the operator be more prone to grasp, this utility model also is convenient to clinical desired irrigation and disinfection.

1 is syringe needle among the figure, the 2nd, and aperture, the 3rd, the shape of a hoof " pin hole.

Claims

1, a kind of porous multi-orientation type injection needle is characterized in that having some apertures 2 on the front end side wall of syringe needle 1, they communicate with " shape of a hoof " pin hole 3 of needle tip.

2, by the described porous multi-orientation type of claim 1 injection needle, the some apertures 2 that it is characterized in that syringe needle 1 front end concentrate in 1/3 section of the front end of syringe needle 1 relatively.

3, by claim 1,2 described porous multi-orientation type injection needles, there is certain interval the position that it is characterized in that some apertures 2 on syringe needle 1 front end side wall each aperture in vertical direction, and the angle α between the longitudinal axis of aperture and syringe needle 1 is not less than 30 ° in twos in the horizontal direction.
