Description
Technical field
This utility model relates to medical beauty treatment instrument and medical technical field, particularly relates to a kind of disposable array-type micro injection needle.
Background technology
Injection technique, injection device are being played the part of important role in treating diabetes, in addition with select the insulin preparation no less important, concern the success or failure of glycemic control.A lot of medical personnel usually ignore the influence of injection technique to glycemic control itself with the diabetics of accepting injection of insulin.The clinician considers not reach the reason of expection glycemic control target from insulin preparation, blood glucose self-monitoring equal angles through regular meeting; But ignored the influence of injection technique, and insulin is an important link through the process that plays a role in the injection device entering human body to glycemic control.Because the partes corporis humani position is to the absorption property of there are differences of insulin, injection of insulin is to subcutaneous still Musclar layer, and there is very big-difference in its absorption rate, and the absorption of insulin situation of resting state and kinestate muscle also has very big variation.Optimize the injection of insulin technology, comprise the syringe needle of selecting appropriate length, note correct injection maneuver, standard ground is the injection site by turns, avoids intramuscular injection etc., and these are significant to obtaining good glycemic control.
China's injection of insulin state of the art survey result shows, has 31.1% patient infusion position to occur lump approximately, wherein ninety percent occurs in abdominal part, but still has the patient to be chosen in the injection of adipose hyperplasia position.Because insulin itself is kind of a somatomedin, can cause this position subcutaneous fat hypertrophy and produce scleroma in the injection of same position repeatedly, injection here again, the absorbance of insulin will descend, and the long glycemic control that causes of soak time is unstable.Investigation shows, has three one-tenth diabeticss when abdominal part is injected, not pinch skin approximately.If usefulness is 8 millimeters syringe needles at this moment, just possibly cause the danger of intramuscular injection, accelerate absorption of insulin, the influence performance.Simultaneously, though also have half patient pinching injection of skin, unclamped the skin pleat too early.In fact, the position that human body is fit to insulin injection is abdominal part only not, and big leg outer side, arm 1/4 place, the outside and buttocks can.Referring to by turns between abdominal part, arm, thigh, buttocks of different injection sites injected by turns, adopts the method for rotating the injection site effectively to improve curative effect, avoids the probability that develops complications.The injection of insulin needle length is different, and injection angles, maneuver are also different.As to use length be 8 millimeters, 12.7 millimeters syringe needle, must pinch skin during injection and with the 45 injection, to increase subcutaneous tissue thickness, reduce the risk with injection of insulin to Musclar layer.If use 5 millimeters ultra-fine ultrashort type pen type syringe needles, then need not to pinch skin, directly vertical inserting needle all thrusts subcutaneous getting final product with syringe needle, and 5 millimeters syringe needles can reduce pain, improve the injection compliance.
Pen-type insulin injection is simple and convenient and easy to study because of having, dosage accurately, make things convenient for advantages such as durable, hypodynia, effect be good, apply to diabetics comparatively widely.Existing clinical promise and the syringe needle that pen and excellent companion II pen etc. is equipped with 8mm * 30G of using injected more, and according to operation instruction, injection back syringe needle need be stayed subcutaneous 6 seconds at least to more than 10 seconds, and continues to pin push button, extracts fully until syringe needle.In practical operation fail in the short time to spread fully and absorb because inject subcutaneous medicinal liquid, by the aforesaid operations method still regular meeting have medicinal liquid to ooze from pinprick, so just can't guarantee the accuracy of therapeutic dose.
The needle tubing length of existing injection needles head is usually greater than 15 millimeters; Even being 0.25 millimeter ultra-fine needle tubing length, the diameter that the injection needles head on the insulin injection pen adopts also reaches 4.5 millimeters～12 millimeters; As do not adopt pinch the skin maneuver can not be directly vertically to the injection of positions such as arm, and pain on injection still can let many patients, and especially infant is forbidding.Owing to have only a needle tubing on each syringe needle, under the situation of the same dosage of injection, needle tubing length is short more, though can reduce pain, when injecting with injection after, syringe needle all must be stayed Intradermal, the wait abundant absorbed time of medicinal liquid must obviously increase.Above-mentioned factor can be brought many inconvenience to patient undoubtedly, and To know is easy, but to do is difficult, has reduced patient and has adopted correct method to carry out the compliance of injection for curing, and affected the treatment.
