Embodiment Construction

[0015] like figure 1 , 2 As shown, the disposable obstetric membrane disruptor includes an air bag 1, a piston pump 2, a suction tube 3, a suction cup 4, and a puncture needle 5. The suction tube 3 is a long and thin transparent plastic tube. The diameter of 2 is greater than the diameter of suction pipe 3, forms stepped 8 at the junction of piston pump and suction pipe, and the front end of suction pipe 3 is connected with a trumpet-shaped suction cup 4, and suction cup 4 is elastic rubber material, and the periphery of suction cup 4 will be smooth, In order to be in good contact with the fetal membrane, the rear end of the piston pump 2 is connected to the air bag 1, and a piston 6 is arranged in the piston 2, and one end of the puncture needle 5 located in the suction tube 3 is fixed on the piston 6, and the front end of the puncture needle 5 Stretch out the suction cup 4, the suction cup 4 is provided with a plurality of suction holes 7 communicated with the suction pipe ...

Abstract

The invention discloses a disposable obstetrical membrane rupture device which comprises an air bag, a piston pump, a sucking pipe, a sucking disc and a puncture needle, wherein the sucking pipe is in a slender tubular shape, and the sucking pipe and the piston pump are integrated; the front end of the sucking pipe is connected with the bell-shaped sucking disc, and the back end of the piston pump is connected with the air bag; a piston is arranged in the piston pump, and one end, which is positioned in the sucking pipe, of a needle body is fixed on the piston; and a plurality of sucking holes arranged on the sucking disc are communicated with the sucking pipe. The distance between the piston and a step part in which the sucking pipe is connected with the piston pump is equal to the length of the needle body extending out the plain end of the sucking disk, i.e., the membrane rupture depth; since the distance is set when the device is shipped out of the factory, when the disposable obstetrical membrane rupture device is used, the extending length of a needle head, i.e., the membrane rupture depth is certain, thereby overcoming the defect that the depth of the needle head can not be preferably controlled by experience to injure fetuses when an ordinary membrane rupture device is used.

Description

technical field [0001] The invention belongs to the clinical auxiliary equipment of obstetrics and gynecology, and in particular relates to a membrane rupturer for obstetrics of uterine weakness in active phase. Background technique [0002] In clinical obstetrics, for women with uterine atony and difficult uterine contractions in the active phase, artificial rupture of membranes is generally used to help give birth. There are many problems with the membrane rupturer used. For example, the patent No. 200620160991.0 is "an artificial membrane disruptor", the structure of which is: an operating handle is fixed on the needle sleeve guide tube, the membrane rupture needle passes through the needle sleeve guide tube, the needle handle and the rupture Membrane pins are fixedly connected. The membrane breaker is reasonable in structure, novel and practical, but has the problem of single function, that is, it only plays the role of breaking the membrane, and the drainage problem a...
