Amniotic fluid membrane rupture device and use method thereof

Abstract

The invention discloses an amniotic fluid membrane rupture device and a use method thereof. The device comprises an outer cylinder internally provided with a cavity, and the inner wall of the upper end of the outer cylinder is connected with an elastic inner ring which is annularly arranged; a push rod matched with the inner ring is slidably connected into the outer cylinder, a membrane rupture needle is arranged at the end, close to the inner ring, of the push rod, and an amniotic fluid drainage tube is arranged in the push rod; a gap used for clamping an amniotic fluid membrane is reserved between the inner ring and the outer cylinder, the outer cylinder is provided with an air exhaust pipeline, the air exhaust pipeline is communicated with the gap, and the air exhaust pipeline is further connected with an air exhaust device. The device is easy to operate, wherein the clamping work of an amniotic fluid membrane and the push rod can be achieved; after clamping is completed, the membrane rupture needle automatically rebounds after membrane rupture work, a fetus is prevented from being scratched, collection work of amniotic fluid is facilitated, and the use safety of the product is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an amniotic fluid rupture device and a method for using the same. Background technique [0002] Artificial rupture of membranes means artificially intervening to tear the amniotic membrane at the cervix in order to observe the color of amniotic fluid, strengthen uterine contractions, and accelerate the progress of labor. It is a common way of inducing labor during natural childbirth. During artificial membrane rupture, a membrane rupturer is required. At present, in the clinical amniotic surgery of obstetrics and gynecology, most of the amniotic membranes including the fetus are directly punctured through a needle to make the amniotic fluid flow out. [0003] This method of breaking the membrane, first of all, is the adsorption of the membrane. Whether it is before or after the membrane is broken, the clamping is not reliable, and sometimes the membrane cannot be clamped...

AI Technical Summary

Problems solved by technology

[0003] This method of breaking the membrane, first of all, is the adsorption of the membrane. Whether it is before or after the membrane is broken, the clamping is not reliable, and sometimes the membrane cannot be clamped; and after the membrane is broken, some inside the membrane breaker The structure is directly washed by the amniotic fluid, and it is inconvenient to clean up later; after the rupture of the membrane, the amniotic fluid not only flows out from the inside, but also flows out from the outer cylinder of the membrane rupturer, causing great inconvenience to the collection and observation of amniotic fluid
