Abstract

A novel vein transfusion needle comprises a transfusion tube, a joint and a needle tube. A conical needle tip is arranged at the front end of the needle tube; a block section is arranged in the front of the needle tip; and a plurality of liquid outlet holes are evenly distributed in the rear of the block section of the needle tip. The novel vein transfusion needle has the advantages of more smooth transfusion, and avoidance of transfusing liquid into muscles when patients carelessly move and puncture a blood vessel wall by the needle tip.

Description

A kind of novel venoclysis needle

Technical field

This utility model relates to medical apparatus and instruments, particularly venoclysis needle.

Background technology

Transfusion needle is to be used for medical apparatus and instruments commonly used such as venous transfusion and blood sampling.Existing venoclysis needle is by tube for transfusion, needle stand (being equivalent to joint), and syringe needle constitutes.When doing venous transfusion or blood sampling, after skin degerming was handled, the medical worker penetrated syringe needle in the vein, and the wrapping of reuse adhesive plaster is fixing.Yet; existing needle point profile is an oblique plane, with horizontal direction (being the axial angle of the needle body＜30 degree), in the middle of usual transfusion; because transfusion time is long; in infusion process, the patient unavoidably can be movable, Just because of this; regular meeting is because infusion needle piercing blood vessel wall; cause liquid input muscle, and acupuncture treatment again can increase more misery to patient.Secondly, owing to have only a liquid outlet on the existing needle point, easily obstruction, not smooth causes infusing.Increase workload to the medical worker like this, also increased some conflict between doctors and patients.

The utility model content

The purpose of this utility model provides the more unobstructed a kind of novel venoclysis needle of a kind of transfusion, and avoids syringe needle to penetrate blood vessel and cause liquid input muscle.

This novel purpose is achieved in that a kind of novel venoclysis needle, comprises tube for transfusion, joint, needle tubing, and the needle point of needle tubing front end is a cone tip, and there is a block section needle point front portion, and the rear portion, block section is evenly equipped with a plurality of liquid outlets on the needle point.

The liquid outlet at rear portion, above-mentioned needle point block section is provided with two row along needle point axis direction circumference, whenever shows three, and two row liquid outlets shift to install.

The length of block section is 2～10mm on the above-mentioned needle point.

The beneficial effects of the utility model are:

1, when transfusion, uniform two row on the syringe needle, totally 6 liquid outlets certainly, also can design 8 according to syringe needle size, liquid outlet, and therefore the probability of stopping up reduces, transfusion is more unobstructed.

2, with the front end shutoff of syringe needle, change wire tip profile and be conical (being sharp cone distal), in long-time infusion process, syringe needle produces the part and moves displacement, even the needle pierces blood vessel wall can not cause the liquid mistake to import the problem of muscle yet.

3, this novel pin is improved the transfusion needle that uses for a long time, has the good characteristics of novel, simple in structure, clinical result of use.This is novel will be accepted and welcome by doctor and patient.

Description of drawings

Fig. 1 is this novel structure chart;

Fig. 2, Fig. 3 are respectively the profile of Fig. 1 along A-A line and B-B line.

The specific embodiment

Fig. 1 illustrates, basis is novel mainly to be made up of tube for transfusion 1, joint 2, needle tubing 3 etc., and the needle point 5 of needle tubing 3 front ends is a cone tip 5, and there is a block section needle point 5 front portions, the rear portion, block section is evenly equipped with a plurality of liquid outlets 4 (joint is equivalent to needle stand, and needle tubing is equivalent to the needle body) on the needle point.The perforate (not shown in figure 1) of syringe needle front end can adopt the welding shutoff, or the shutoff of health level plastics.Referring to Fig. 2 Fig. 3, the liquid outlet 4 at rear portion, needle point 5 block section is provided with two row along needle point axis direction needle tubing circumference, whenever shows three, and two row liquid outlets shift to install.The length of block section is 2～10mm (we can say that also liquid outlet has two circles, 3 on every circle) on the needle point 5.

Tube for transfusion adopts health level flexible plastic to make, and joint adopts health level rigid plastics, and needle tubing adopts metal to make.

In infusion process, liquid arrives transfusion needle connector (being joint 2) through tube for transfusion 1, is needle tubing 3 by the transfusion needle body again, and 2～10mm is long to be shut because needle point 5 front ends have, so liquid can only be that liquid outlet 4 flows out by liquid outlet.When making needle point piercing blood vessel wall, liquid can not flow out blood vessel input muscle yet in that transfusion person is careless movable like this, moreover, can be because of sometimes because the former thereby not smooth problem that causes infusing of syringe needle direction yet.

During actual fabrication, should try one's best near the block section in the hole of liquid shown in Fig. 1.

Claims

1. novel venoclysis needle, comprise that tube for transfusion (1), joint (2), needle tubing (3) is characterized in that: the needle point (5) of described needle tubing (3) front end is a cone tip (5), and there is a block section needle point (5) front portion, and the rear portion, block section is evenly equipped with a plurality of liquid outlets (4) on the needle point.

2. according to the described a kind of novel venoclysis needle of claim 1, it is characterized in that: the liquid outlet (4) at described needle point (5) rear portion, block section is provided with two row along needle point axis direction circumference, whenever shows three, and two row liquid outlets shift to install.

3. according to claim 1 or 2 described a kind of novel venoclysis needles, it is characterized in that: the length that described needle point (5) is gone up the block section is 2～10mm.
