Artificial membrane rupturing needle

The utility model relates to an artificial membrane rupturing needle which is a combination of a membrane rupturing needle body and an injector and has the same size as a 1-milliliter injector. The needle head of the membrane rupturing needle body is contained in a needle cylinder of the injector and can freely go forwards and backwards within a certain range, the length of the needle head is about 10mm to 15mm, and a portion, exposed out of a nipple, of a forwards-pushing piston is about 3mm. The needle head is fixed on the head portion of the piston of the injector, a sealing pad is arranged on the piston head portion, and when the piston is drawn back, a front hole in the nipple can be used for sucking amniotic fluid. Two self-destroying side wings are arranged at the rear end of the piston of the injector, the two self-destroying side wings are ejected after the piston is drawn for a certain scales, and the piston is prevented from pushing the needle head forwards to be repeatedly used after exposure agai
