Anti-overflow amniotic fluid breaking membrane drainage device for gynecology and obstetrics

Abstract

The invention discloses an anti-overflow amniotic fluid breaking membrane drainage device for gynecology and obstetrics, belongs to the technical field of medical instruments, and solves the problemsthat the rupture membrane of the existing amniotic fluid rupture membrane device is easy to injure the fetus and the operation safety is poor, and the amniotic fluid overflows. The technical essentials of the invention are as follows: the device comprises an arc-shaped top end, a liquid storage cylinder, a push handle and a holding cylinder, and the liquid storage cylinder and the holding cylinderare connected as one body; the push handle is pushed to make the push rod and the puncture head slide steadily in the direction of the metal drainage tube, the ruptured needle pierces the puncture hole to puncture the fetal membrane, the amniotic fluid is easy to break and safe, and the amniotic fluid can be drained without injuring the fetus; and, secondly, the amniotic fluid is sucked out by the amniotic fluid collecting tube and drainage tube, the puncture needle is automatically retracted under the spring tension, and the annular protrusion and anti-overflow cover slow down and prevent the overflow of amniotic fluid, which is conducive to the drainage operation of amniotic fluid.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-overflow amniotic fluid membrane drainage device for obstetrics and gynecology. 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 operation, the amniotic membrane is generally inhaled by negative pressure of the membrane rupture device, and the amniotic membrane is punctured by the membrane rupture needle, and then the amniotic fluid is inhaled. Since the membrane rupture device is inserted into the genitals for convenience, the front end of the membrane rupt...

Problems solved by technology

[0004] Although both can puncture the amniotic membrane and avoid infection caused by amniotic fluid overflow, the device requires a large suction force when puncturing the amniotic membrane, and its sealing performance is difficult to achieve in actual operation, which may cause repeated operations and still fail to rupture the membrane. Or due to the large thickness of the fetal membrane, a number of rupture needles fixed near the inner wall of the front end of the liquid storage cylinder cannot puncture the fetal membrane, thereby affecting the normal progress of the mother's clinical or high-level rupture of the membran
