Description
Technical field
This utility model relates to a kind of needle for anaesthesia head, belongs to medical instruments field.
Background technology
Along with the develop rapidly of science and technology, medical level is also in continuous raising, people pursue the therapeutic scheme of painlessization more, therefore the attention also more and more obtaining people is anaesthetized, the medical apparatus and instruments of anesthesia is also constantly being developed and is innovating, and final purpose is in order to faster, better, more effective treatment;
But current anesthetic needle head but can not allow people satisfied, especially when major operation, whole anesthesia may be needed, but current most anesthetic needle head only has a medicine outlet hole, therefore drug speed is slow, the time that medicine is diffused into human body is just long, and sometimes also need to possess many places anesthesia, patient among a small circle will be caused like this to have suffered spininess, the drug effect of the little syringe of sometimes major operation is not enough to support in addition, just need again to inject again changing syringe after garter, such sufferer also will repeat acupuncture treatment; Moreover people likely can not an injecting anesthetic medicine in the process of operation, other medicines may be injected in addition, so also there will be the situation repeating to have an acupuncture treatment, therefore a lot of patient very misery of bringing of space multiple injection, this respect needs us to carry out innovation and creation to medical apparatus and instruments really, avoids with this.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of needle for anaesthesia head, and can determine the length injecting human body accurately, and administration is rapid, administration range is large, also avoid simultaneously and repeats the misery brought to sufferer of having an acupuncture treatment.
This utility model solves the technical scheme that its technical problem adopts: provide a kind of needle for anaesthesia head, comprise hollow needle body, it is characterized in that described hollow needle body is evenly provided with scale, first 1/3 section of hollow needle body is evenly provided with medicine outlet hole, one end of hollow needle rear end connecting tee, the other two ends of threeway connect tube for transfusion respectively.
Be arranged so that the insertion depth of needle body more precisely puts in place by scale, administration is more abundant;
The needle body surrounding of the first 1/3 section evenly densely covered medicine outlet hole of described hollow needle body.
By the setting of evenly densely covered medicine outlet hole, make injection speed faster, also improve administration range simultaneously, avoid the multiple injection among a small circle; In addition because hollow needle body can not all be inserted in human body, therefore medicine outlet hole can not gather whole hollow needle body, flow process in the medicine outlet hole that such anesthetics never will insert human body, through test, when anesthesia injection, 1/3 of leading portion is bound to insert in human body, therefore before hollow needle body, 1/3 densely covered medicine outlet hole is no problem, is also preferred plan.
The leading portion of described hollow needle body is most advanced and sophisticated setting.
Most advanced and sophisticated penetrating of conveniently anesthetic needle is set mainly, also alleviates the misery of patient accordingly.
The tube for transfusion that the other two ends of described threeway connect respectively is provided with check valve.
Two tube for transfusions must use simultaneously, two syringes are connected respectively on the syringe interface of wherein two tube for transfusions, then check valve is opened, Exhaust Gas simultaneously, then human body is penetrated, by threeway, the anesthetics in two syringes is injected human body simultaneously, it also avoid like this and repeat the misery brought to people of having an acupuncture treatment.
The end of the tube for transfusion that the other two ends of described threeway connect respectively is provided with syringe interface.
Described threeway is four-way.
The use of four-way is identical with threeway principle, can inject the medicine of 3 syringes simultaneously.
The beneficial effects of the utility model are:
1, be arranged so that the insertion depth of needle body more precisely puts in place by scale, administration is more abundant, and drug effect plays also better;
2, by the setting of evenly densely covered medicine outlet hole, make injection speed faster, also improve administration range simultaneously, avoid the multiple injection among a small circle;
3, two tube for transfusions must use simultaneously, two syringes are connected respectively on the syringe interface of wherein two tube for transfusions, medicine needs being penetrated human body for twice can once inject into, it also avoid and repeats the worries brought to sufferer of having an acupuncture treatment, alleviate the misery of sufferer.
