Description
Technical field
The present invention relates to medical apparatus and instruments, beauty treatment instrument and medical art, particularly relate to a kind of metal needle tubing array element and injection needle thereof.
Background technology
Injection technique, injection device play key player in the disease treatment such as medical cosmetology and diabetes.In recent years, beauty treatment is increasingly universal with plastic surgery in the world, and disposable syringe has been widely used in the implant injection to the faces such as forehead, canthus, glabella, nasolabial fold, the corners of the mouth, neck and other position of health.Usually need evenly to inject at the certain depth place of a panel region in plastic surgery, and existing entry needle all only has single needle tubing, at this moment can only repeatedly inject, treatment time is long, patient suffering is large and be difficult to ensure the uniformity of injection and affect the treatment.If market can provide a kind of high-quality injection needle with needle tubing array, the problems referred to above will be readily solved undoubtedly.
At present, tatoo and become a kind of fashion, be day by day subject to the especially vast teen-age approval of domestic and international personage and pursue, but the pain of tatooing in process and to be hemorrhagely but quite bound to arouse fear.What generally adopt due to existing tattooing needle is solid needle array, repastes dyestuff after must first pricking out the pattern on skin.In order to allow dyestuff can enter skin to obtain satisfied effect of tatooing, just must allow the enough dark of acupuncture, pin pin must be caused like this to see, and blood and huge pain are until numbness, can bring very large potential safety hazard undoubtedly.In addition, with advancing age with the transition of society, now existing many personages urgently wish to remove existing singular tattoo design, but comparatively dark due to what be needled into, and the work that removal is tatooed becomes very difficult, and their body and mind can meet with tribulation again undoubtedly therebetween.If the syringe with short and small, very thin hollow array syringe needle can be adopted to replace solid needle array, tattooing injects dyestuff while enforcement is thrust, so only need by the horny layer of syringe needle transdermal outermost thickness about 50 microns-100 microns, owing to not touching nerve and blood vessel, whole process is painless, depletion of blood, safe and reliable, and gratifying effect of tatooing can be obtained.In addition, from now on just in case think that removal singular tattoo design undoubtedly can be much easy, relieved.
Pen-type insulin injection because of have simple and convenient and easy to study, dosage accurate, facilitate the advantages such as durable, hypodynia, effect are good, apply to diabetics comparatively widely.Even if the injection needles head employing diameter on existing insulin injection pen is the ultra-fine needle tubing of 0.25 millimeter, its length still reaches 5 millimeters ~ 12 millimeters, pinching skin maneuver if do not adopted can not the directly effectively therapentic part injection such as Vertical dimension arm, and pain during injection still can allow many patients especially infant inspire awe even from distance.Owing to each syringe needle only having a needle tubing, when inject with dose, needle tubing length is shorter, although can reduce pain, injection time with injection after, syringe needle all must stay Intradermal, wait for the medicinal liquid abundant absorbed time must obviously increase.Above-mentioned factor can bring much inconvenience to patient undoubtedly, and To know is easy, but to do is difficult, reduces patient and adopts correct method to carry out the compliance of injection for curing, and affect the treatment.If short and small, very thin needle tubing array can be adopted to substitute single needle tubing on this syringe needle, all effective therapentic parts such as abdominal part, thigh, arm of health all can be implemented safety, convenient, rapidly, painlessly vertical injection, the welcome of insulin injection pen user will be subject to undoubtedly.
In existing injection needles head, all adopt sqtructural adhesive needle tubing to be fixed on one end of conical tube needle stand.When only have a needle tubing and not only thick but also long, utilize point gum machine or manual operation and select suitable sqtructural adhesive all can complete needle tubing steady job high-quality on this needle stand, efficiently, and guaranteeing that the one end of inserting needle tubing is unimpeded.But, when many not only thin but also short needle tubings rearrange needle tubing array according to a determining deviation, existing needle stand structure and needle tubing technique for fixing cannot be adopted to manufacture.
