Improved safe and efficient membrane rupture device for obstetrics and gynecology department and application method

Abstract

The invention provides an improved safe and efficient membrane rupture device for the obstetrics and gynecology department and an application method, belongs to the field of medical instruments for the obstetrics and gynecology department and aims at solving the problem that an existing membrane rupture device in unsafe in use. The improved safe and efficient membrane rupture device for the obstetrics and gynecology department comprises a membrane rupture tube, a push rod, a baffle plate and a connecting rod, wherein a piston is fixed at the front end of the push rod; the outer wall of the piston is hermetically laminated with the inner wall of the membrane rupture tube; the front end of the connecting rod is connected to the bottom surface of the baffle plate; a liquid inlet hole is formed in the baffle plate; the outer edge of the baffle plate is hermetically laminated with the inner wall of the membrane rupture tube; a bumping post is formed at the center position of the top surface of the baffle plate; rod holes are formed in the piston and the push rod; the rear end of the connecting rod is movably arranged in the rod holes in a penetrating manner; spline teeth and spline grooves are arranged on the rod wall of the connecting rod and the hole walls of the rod holes; a baffle ring is fixed on the inner wall of the membrane rupture tube; the rear end of a membrane rupture needle is fixed on the inner edge of the baffle ring; a slide chute is arranged in the inner wall of the membrane rupture tube and extends along the circumferential direction and the axial direction of the membrane rupture tube; a locating groove is formed in the middle of the slide chute; and a slide block embedded into the slide chute is arranged on the outer edge of the baffle plate. The membrane rupture device is convenient to operate and safer in use.

Description

technical field [0001] The invention belongs to the technical field of obstetrics and gynecology medical devices, and relates to an improved safe and efficient obstetrics and gynecology membrane rupturer 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 aspirated by a membrane rupture device with a syringe structure, but there are at least the following problems in the process of aspiration of amniotic fluid: [0003] 1. The fetal membrane is continuously attracted by negative pressure, so that the puncture need...

AI Technical Summary

Problems solved by technology

[0003] 1. The fetal membrane is continuously attracted by negative pressure, so that the puncture needle continues to work, which is easy to cause danger;

[0004] 2. The fetal membrane is continuously attracted by negative pressure, so the fetal membrane part will enter the rupture tube, and pulling out the rupture tube forcibly will easily cause danger;

[0005] 3. The amniotic fluid in the rupture tube cannot be quickly closed during the process of taking out the rupture tube, so the amniotic fluid in the rupture tube is easy to dump and cause infection
