Description
Technical field:
The utility model is related to Dispoable medical syringe needle, more particularly to a kind of medical needle without interior wound.
Background technology：
Medical needle is a kind of people's medicine equipment the most well known, it is sick after to have an injection, transfuse blood and infuse be most conventional
Treatment means, although existing medical needle obtained official standard, GB15811-2001《Disposable aseptic injection pin》With
GB18671-2009《Disposable intravenous infusion needle》, there are many shortcomings in existing medical needle, as the Yang Changyan in Kunming exists
Described in this description such, " existing medical needle of Chinese patent 200610112919.5 and 200810222767.3
Structure is typically to be processed with stainless steel tubule, to form the first inclined-plane in one end of stainless steel tube to cut for the first time, then
The second cambered surface is formed in the front end on the first inclined-plane by second of cutting on the basis of the first inclined-plane, because stainless steel tube has
Certain thickness, by secondary cutting, the inwall of needle point liquid outlet stainless steel tubule can form cutting edge of a knife or a sword mouthful in pin, tubule outer wall then
Form needle point external-open cutting edge of a knife or a sword mouthful.The syringe needle of this structure is used for when having an injection, infuse and transfusing blood, successively with the second cambered surface of needle point, the
One inclined-plane, puncture tissue, break tissue, it is ensured that decoction flows into blood from stainless steel thin tube inner wall by cutting edge of a knife or a sword mouthful outside needle point
In pipe or human body meat tissue, in inserting needle operation, the second cambered surface to human body without interior wound, and the interior cutting edge of a knife or a sword on the first inclined-plane mouth and external-open
Splitter is staggered to form between cutting edge of a knife or a sword mouthful, the tissue touched can be extractd during inserting needle, the interior surface of a wound is formed." this is to be assorted
People when puncturing such as have an injection, transfuse blood and infuse can feel the main cause of very pain, and carefulness impression is being had an injection, transfused blood every time
With three pain can be all felt in infusion process, i.e., puncture starting, depth into and out three moment, while in the patent
This kind of syringe needle issuable main harm species in use is also described in document.
Utility model content：
In order to overcome the shortcomings of that existing syringe needle is present, the purpose of this utility model is to provide a kind of medical without interior wound hypodynia sense
Syringe needle, it can eliminate have an injection, transfuse blood and infusion process in pain of the depth into and out two moment, mitigation is being worn
The pain and amount of bleeding of thorn starting are qualified without interior wound hypodynia sense medical needle.
The technical scheme that the utility model is taken is as follows：
It is a kind of to create hypodynia sense medical needle, including syringe needle tubule without interior, it is characterized in that：In the front end of syringe needle tubule provided with a left side
Second inclined-plane, right second inclined-plane and the first inclined-plane, left second inclined-plane, right second inclined-plane and syringe needle tubule three are on the preceding top of syringe needle
Needle point is formed, cylindrical formed between left second inclined-plane or right second inclined-plane of syringe needle tubule punctures outer cutting edge, syringe needle tubule
Formed between endoporus and left second inclined-plane or right second inclined-plane and puncture inner cutter hole, shape between the endoporus of syringe needle tubule and the first inclined-plane
Cutting edge of a knife or a sword mouthful is cut into interior wound circular arc, a radial direction cutting edge is respectively formed between left second inclined-plane, right second inclined-plane and the first inclined-plane, is punctured
Inner cutter hole is sharp keen cutting edge section close to needle tip, and it is that circular arc oppresses section, the interior wound to puncture inner cutter hole close to radial direction cutting edge one end
The cross sectional shape that circular arc cuts cutting edge of a knife or a sword mouthful vertical section is circular arc, and the arc radius on the interior wound circular arc circular arc top of cutting cutting edge of a knife or a sword mouthful is more than
Connected between the arc radius of both sides, radial direction cutting edge and the first inclined-plane and left second inclined-plane or right second inclined-plane for arc transition.
Further, the length of sharp keen cutting edge section is the 15%~50% of puncture inner cutter hole total length.
Further, the length of the sharp keen cutting edge section is the 30% of puncture inner cutter hole total length.
The structure that the utility model has carried out three aspects to the tip portion of existing medical needle is improved, and achieves difficulty
With the technique effect of expectation：
First, the puncture inner cutter hole formed between the endoporus of syringe needle tubule and left second inclined-plane or right second inclined-plane is divided into
Two sections, be sharp keen cutting edge section close to needle tip, is that circular arc oppresses section close to radial direction cutting edge one end, circular arc oppresses the axial cross section of section
Shape is changed to arc surface, circular arc is oppressed section and loses interior cutting edge of a knife or a sword mouthful effect, during inserting needle, by needle point, two sharp keen cutting edge sections, by syringe needle
Cylindrical two formed between left second inclined-plane, right second inclined-plane of tubule puncture outer cutting edge and complete to puncture cut jointly, so
Afterwards outer cutting edges are punctured by two to continue to expand broken wall, by circular arc oppress section and the common completion of needle tubing outer wall to acupuncture skin histology or
The hemostasis by compression analgesic of blood vessel, realizes needle point after puncturing without pain；If by circular arc oppress section section arc radius be designed to by
Gradual change is big, and effect is more preferable.
Second, the interior wound circular arc formed between the endoporus of syringe needle tubule and the first inclined-plane is cut into cutting edge of a knife or a sword mouthful and carries out radiused set
Meter, make it both will not subcutis or blood vessel produce secondary shearing, form secondary shearing pain, and same to having been formed
The surface of a wound realize hemostasis by compression and analgesic.
3rd, the radial direction cutting edge formed between left second inclined-plane, right second inclined-plane and the first inclined-plane is subjected to smooth circular arc
Design, is connected between radial direction cutting edge and the first inclined-plane and left second inclined-plane or right second inclined-plane for arc transition.So, pin is gone out
When, radial direction cutting edge will not to wound face carry out three times draw thorn, eliminate the third time during having an injection puncture generation pain and
Bleeding.
