Safe and efficient membrane rupture device for obstetrics and gynecology department and application method thereof

Abstract

The invention provides a safe and efficient membrane rupture device for the obstetrics and gynecology department and an application method thereof, belongs to the field of medical instruments for the obstetrics and gynecology department, and is intended to solve the problem that an existing membrane rupture device is unsafe in use. The safe and efficient membrane rupture device comprises a membrane rupture tube, an adjusting seat, a push rod and a membrane rupture needle, wherein the adjusting seat comprises an outer adjusting sleeve, an inner adjusting sleeve and an adjusting plate; a ventilation channel is arranged in the membrane rupture tube; an air hole is formed in the wall of the outer adjusting sleeve; the push rod extends into the membrane rupture tube from the rear end of the membrane rupture tube; a piston which is in movable fit with the inner wall of the outer adjusting sleeve hermetically is fixed at the front end of the push rod; a needle installation hole is formed in the wall of the front end of the outer adjusting sleeve; a needle installation groove is formed in one end of the needle installation hole corresponding to the outer wall of the outer adjusting sleeve; a magnetic stop block is fixed at the rear end of the membrane rupture needle and a needle tip is arranged at the front end of the membrane rupture needle; a needle hiding groove is formed in the inner wall of the membrane rupture tube along the radial direction; and a magnetic block is arranged at the bottom of the needle hiding groove. The membrane rupture device is safe in use and high in operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of obstetrics and gynecology medical devices, and relates to a safe and efficient obstetrics and gynecology membrane rupture device and its use method. Background technique [0002] At present, in clinical obstetrics, for women with uterine atony and difficult contractions in the active phase, it is generally necessary to use artificial rupture of membranes to help give birth. Artificial rupture of membranes is an artificial way to intervene and tear the membranes at the cervix in order to observe the color of amniotic fluid, strengthen uterine contractions, and accelerate the progress of labor. In clinical operations, amniotic fluid is usually sucked by a membrane rupture device with a syringe structure, but in the process of sucking amniotic fluid, there are at least the following problems: [0003] 1. The fetal membrane is continuously attracted by negative pressure, so that the puncture needle continues...
