Abstract
The utility model relates to a syringe needle which is used on syringes. The safety syringe needle also comprises a needle body and a needle head, but an annular small groove and a fixed ball are arranged on the needle head. The phenomenon that when syringe needles are broken during injection, the broken needles are completely buried in tissue can not occur. The operation is safe and reliable.
Description
A kind of injection needle that this utility model relates to use on the syringe.
Present widely used injection needle is made up of head and body, and the deficiencies in the prior art part mainly is: when the medical personnel gave patient infusion, for some reason, for example child patient or psychentonia patient etc. were because of pain or uncomfortable the swing; Perhaps as being missed, pin thrusts ligament or bone wall because of medical personnel's error, and too exert oneself etc. former again thus cause injection needle to fracture after be embedded in the tissue fully, especially the athletic meeting of health causes the broken needle migration, not only bring unnecessary misery, return the medical personnel and bring unnecessary trouble to the patient.According to the clinical data statistics, the metal fragment that stays in the body is that broken needle accounting example is maximum.
The purpose of this utility model is to avoid weak point of the prior art, even and provide a kind of and in when injection injection needle take place and fracture, can not occur broken needle yet and be embedded in in-house safety needle product fully.
Can take following technical scheme to realize purpose.The safety injection needle still comprises head and body, but its head is provided with the little recessed and fixing ball of ring.
Because on the head of injection needle, there is ring little recessed near body design, makes the pipe thickness of the little recess of ring thin slightly, so just feasible the ring a little less than the stressed book of little recess than other position pipe thickness, if, can only fracture at the little recess of ring so guaranteed under the situation of unexpected generation broken needle.At the fixing ball of one of the little depressed portions adjacent of ring design, its effect is to guarantee when injection, injection needle enter in the body the longest can only be head fixedly ball with the lower part.For a short time, recessedly be exposed at externally so guarantee to encircle, even taking place under the situation that injection needle fractures, also can only be that the little recess of ring outside being exposed at tissue fractures, this has just prevented injection needle to fracture afterwards, and broken needle be embedded in in-house phenomenon fully.
Under the prerequisite that satisfies the said structure requirement, as for the little recessed degree of depth of ring with fixedly can be determined by circumstances according to producing needs or using needs in diameter, the little position recessed and fixedly ball of ring of ball.
The relative prior art of the technical program has following advantage and effect:
It broken needle can not occur and be embedded in in-house phenomenon fully, uses, and is safe and reliable.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Fig. 1 is a kind of structural representation of safety needle.
Fig. 2 is the little part sketch map recessed and fixedly ball of ring.
The embodiment of injection needle shown in the accompanying drawing, except that head 1 that injection needle is arranged and body 2, it also is provided with little recessed 3, the fixing ball 4 of ring, it encircles and recessedly is provided in a side of the junction of syringe needle and needle body and fixedly on the syringe needle between the ball for a short time, fixedly ball is provided in a side of on the syringe needle that encircles little depressed portions, it is about about 1cm from the junction of syringe needle and needle body, can guarantee to meet injection clinically like this and require----should have the syringe needle about 1cm to be retained in the tissue at least when injection.
Practical function the best of present embodiment.
Claims (3)
1. a safety needle is made of head and body, it is characterized in that: it is little recessed and rise and guarantee the fixedly ball that syringe needle exposes that its head is provided with ring that relative most probable fractures.
2. injection needle as claimed in claim 1 is characterized in that: be provided with fixedly ball on the head of head and body junction one segment distance.
3. injection needle as claimed in claim 1 is characterized in that: in head and body junction with fixedly to be provided with ring on the syringe needle between the ball little recessed.
