Abstract
The utility model relates to a low-trauma puncture needle head which is applicable to a one-time remaining needle. The needle head comprises a needle tip part and a blood overflow groove, wherein the needle tip part consists of a needle tip front end and a needle tip rear segment; the needle tip front end is of the bevel through tube; and the tubular side wall of the needle tip rear segment is provided with a through groove that is communicated with the needle tip front end and is arranged along the axis direction of the needle head. For the low-trauma puncture needle head with the adoption of the technical scheme, when in puncture, the needle tip part of the needle head is convenient to be penetrate into skin; meanwhile, as the tubular side wall of the needle tip rear segment is provided with the through groove that is communicated with the needle tip front end and is arranged along the axis direction of the needle head, the through groove of the needle tip rear segment can not realize complete 'cutting' for the tissue after the needle head is penetrated into the skin, so that the tissue can be maintained to be connected, thereby effectively reducing the 'cutting' for the tissue without cutting 'thrombus'; meanwhile, the injury is weaker relatively, thereby being favorable for tissue repair.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of low-wound piercing needle that is applicable on the disposable remaining needle.
Background technology
At present, be widely used in the piercing needle that the syringe needle on the disposable remaining needle all includes the plastic cement tube for transfusion and is used to puncture, the tube for transfusion of plastic cement is sleeved on the outside of piercing needle, wherein, the effect of syringe needle is that the tube for transfusion of guiding plastic cement punctures in the skin, and intravasation, and the tube for transfusion of plastic cement is that injection is input to the intravital pipeline of people, can easily judge whether to have punctured into blood vessel in order to be suitable for this disposable remaining needle, all a hemorrhage groove is set usually at the back segment of syringe needle.Wherein the needle tip of piercing needle is divided into inclined-plane, the sharp inclined plane shape in edge, promptly forms tip portion with the angled crosscut syringe needle of axis on the syringe needle of pipe; In the time of puncture, the tip portion of syringe needle at first can penetrate tissue again in the intravasation, when penetrate tissue, because the sharp edge of needle point can be carried out " cutting " fully to tissue, causes more tissue to be cut, be punctured in the blood vessel then, the plastic cement tube for transfusion brought in the blood vessel inject, the tissue that is cut down fully forms " thrombosis ", simultaneously repeatedly puncture, bigger to tissue injury, form more cicatrix during recovery, tissue meeting hardening, the difficulty that later puncture is become.
The utility model content
The technical problems to be solved in the utility model is, a kind of low-wound piercing needle that is applicable on the disposable remaining needle is provided, and when puncture, reduces the damage of tissue and the formation of " thrombosis ".
In order to solve the problems of the technologies described above, a kind of low-wound piercing needle that this utility model provides, syringe needle comprises tip portion and hemorrhage groove, tip portion is made up of piped needle point front end and needle point back segment, the needle point front end is the inclined-plane siphunculus, offer groove on the tubular sidewall of needle point back segment, groove is communicated with the needle point front end, and the direction of groove is along the axis direction setting of syringe needle.
Adopt the low-wound piercing needle of technique scheme, when puncturing, during the tip portion penetrate tissue of syringe needle, because the front end of needle point is the inclined-plane siphunculus, help puncture, conveniently thrust in the skin, simultaneously, owing to offer groove on the tubular sidewall of needle point back segment, groove is communicated with the needle point front end, and the direction of groove is along the axis direction setting of syringe needle, after puncture enters skin, the groove of needle point back segment can not carry out " cutting " fully to tissue, make tissue can continue to maintain the connection, effectively reduced tissue is carried out " cutting ", kept the integrity of tissue, just can be injected in the blood vessel after " cutting " fully yet, form " thrombosis ", simultaneously, because damage is less relatively, help drug absorption, can guarantee the curative effect of medicine.
Further, the length of described groove is limited, limit described groove and be communicated with the hemorrhage groove, promptly the extreme length of groove is that the front is communicated with the needle point front end, and the back is communicated with the hemorrhage groove.
Offer on the tubular sidewall of needle point back segment to puncture groove when can keep original puncture function convenient tube for transfusion guiding with plastic cement thrust in the blood vessel, can reduce again histiocytic damage, do not form the cutting thrombosis, practical meaning is arranged in reality clinical.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is a kind of low-wound piercing needle of this utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, embodiment of the present utility model is a kind of low-wound piercing needle that is applicable on the disposable remaining needle, the piercing needle 2 that syringe needle on this disposable remaining needle includes plastic cement tube for transfusion 1 and is used to puncture, the tube for transfusion 1 of plastic cement is sleeved on the outside of piercing needle 2, wherein, the effect of syringe needle 2 is that the tube for transfusion 1 of guiding plastic cement punctures in the skin, and intravasation, the tube for transfusion 2 of plastic cement is that injection is input to the intravital pipeline of people, can easily judge whether to have punctured into blood vessel in order to be suitable for this disposable remaining needle, usually all a hemorrhage groove 3 is set at the back segment of syringe needle, tip portion is made up of piped needle point front end 4 and needle point back segment 5, needle point front end 4 is the inclined-plane siphunculus, offer groove 6 on the tubular sidewall of needle point back segment 5, the front of groove 6 is communicated with needle point front end 3, and the back of groove 6 is communicated with hemorrhage groove 3, and the direction of groove 6 is along the axis direction setting of syringe needle.
Adopt the low-wound piercing needle of technique scheme, when puncturing, the tip portion of syringe needle 2 is when penetrate tissue, because needle point front end 4 is the inclined-plane siphunculus, help puncture, conveniently thrust in the skin, simultaneously, because offer groove 6 on the tubular sidewall of needle point back segment 5, groove 6 is communicated with needle point front end 4, the back of groove 6 is communicated with hemorrhage groove 3, the direction of groove 6 is along the axis direction setting of syringe needle, after puncture entered skin, the groove 6 of needle point back segment 5 can not carry out " cutting " fully to tissue, makes tissue can continue to maintain the connection, effectively reduced tissue has been carried out " cutting ", the integrity that has kept tissue is organized also just can not to be injected in the blood vessel after " cutting ", forms " thrombosis ", simultaneously, because damage is less relatively, helps drug absorption, can guarantee the curative effect of medicine.
