Description
Technical field
The utility model belongs to medical instruments field, is specifically related to a kind of painless injection assistor.
Background technology
Intramuscular injection and subcutaneous injection are the usual ways that people use medicine, medicine is by the intramuscular or subcutaneous of injector to inject to human body suitable position, drug slow is made to absorb the object reaching treatment, except the pain caused because of some drugs self, due to technological operation reason, the pain that injection causes is very common, and the person of being injected is agonizing, especially the medical personnel lacked experience, cause the person of being injected to have a fainting spell during acupuncture treatment sometimes.
The technical key point of the intramuscular injection of painless property or subcutaneous injection is two fast one slow, that is: during injection, inserting needle speed is fast, injection liquid speed is slow, it is fast to pull out needle speed. Having many medical and nursing work personnel can not grasp the technical key point of inserting needle completely at present, this is the major cause causing pain. The syringe that liquid is housed vertically is placed in above the skin sterilized the person of being injected injection site when being injection by the technical key point of the intramuscular injection of painless property or subcutaneous injection inserting needle, mainly utilize wrist power, arm strength is assisted, make syringe needle vertical prick skin rapidly, enter into intramuscular, stop after reaching appropriate depth, like this, due to sharp syringe needle and inserting needle fast, making inject time extremely short, the person of being injected will not have the sensation of pain. Except syringe needle may not sharp except, during inserting needle, to be not orthogonal to skin or speed slow for syringe, then or have vibration, all can cause the pain of the person of being injected. And manual operation, depth of needle is difficult to once reach depth desired, and major part was dark or excessively shallow, if repeatedly inserting needle, makes the person of being injected more painful. There is no intramuscular injection and the different painless complementary apparatus of property having both of subcutaneous injection at present.
Practical novel content
