Gynecology and obstetrics membrane rupture device and use method thereof

Abstract

The invention provides a gynecology and obstetrics membrane rupture device and a use method thereof, and belongs to the field of gynecology and obstetrics medical instruments. By means of the gynecology and obstetrics membrane rupture device, the problems that dangers exist in the use process of existing membrane rupture devices and operation is complicated are solved. The gynecology and obstetrics membrane rupture device comprises a membrane rupture cylinder, and membrane rupture needles are fixed to the inner wall of the front end of the membrane rupture cylinder. The gynecology and obstetrics membrane rupture device further comprises a pushing rod, an inner sleeve, an outer sleeve, an outer cylinder and an inner cylinder, wherein a piston is fixed to the front end of the pushing rod, the outer wall of the piston is attached to the inner wall of the membrane rupture cylinder, the inner wall of the outer cylinder is arranged on the outer wall of the inner cylinder in a sleeving mode, the bottom end of the outer cylinder is everted and connected with the bottom end of the inner sleeve, a top membrane plate is fixed to the inner wall of the top end of the outer cylinder, the bottom end of the inner cylinder is everted and connected with the inner wall of the membrane rupture cylinder, a sealing plate is fixed to the inner wall of the top end of the inner cylinder, an outer liquid inlet hole and an inner liquid inlet hole are formed in the outer cylinder and the inner cylinder, outer air holes are formed in the outer sleeve and the inner sleeve, an inner air hole is formed in the cylinder wall of the membrane rupture cylinder, a first sliding hole, a second sliding hole and a third sliding hole are formed in the inner sleeve, and the membrane rupture needles are arranged in the first sliding hole in a penetrating mode and are pressed against the front end of the first sliding hole. By means of the membrane rupture device, membrane rupture operation can be completed quickly and safely.

Description

technical field [0001] The invention belongs to the technical field of obstetrics and gynecology medical devices, and relates to an obstetrics and gynecology membrane rupture device and a method for using the same. Background technique [0002] At present, in clinical obstetrics, for the parturients with uterine atony and difficult uterine contractions in the active phase, artificial rupture of membranes is generally used to assist in production. Artificial rupture of membranes is an artificial way of intervening to tear the fetal membranes at the cervix in order to observe the color of the amniotic fluid, strengthen uterine contractions, and accelerate the progress of labor. In clinical operations, the membrane-breaking device with a syringe structure is generally used to absorb amniotic fluid, but in the process of inhaling amniotic fluid, there are at least the following problems: [0003] 1. The fetal membrane is continuously attracted by negative pressure, so that the ...
