Obstetric noninvasive membrane rupturing device

Abstract

The invention discloses an obstetric noninvasive membrane rupturing device. The noninvasive membrane rupturing device comprises a cylinder body, a fixing sleeve, a storage cavity, a guide rod, a fixing disc, a membrane rupturing layer, a detection layer, a sealing layer and a handheld part, wherein the fixing sleeve is arranged on the outer circumferential surface of the bottom of the cylinder body, the storage cavity is formed in the top of the cylinder body, the guide rod is arranged in the cylinder body in a sliding mode, the fixing disc is arranged at the top of the guide rod and located in the storage cavity, and the membrane rupture layer is arranged on the fixing disc. The slidable guide rod is arranged on the inner side of the cylinder body, the fixing disc with the membrane rupture layer is installed at the top of the guide rod, when the cylinder body is placed at the cervix uteri inner opening, the guide rod is pushed by hand, the membrane rupture layer on the fixing disc istightly attached to a fetal membrane, a probe and an illuminating lamp are installed on the fixing disc, so that the deep position can be observed; the membrane rupturing barb is of a hook-shaped structure, so that a membrane rupturing barb firstly pierces and enters the uterine membrane and then hooks the uterine membrane by using a barb-shaped structure, the danger to the head of a fetus due tobumping of the fetus is avoided, the success rate of membrane rupturing is effectively increased, and meanwhile, the membrane rupturing process is safe and comfortable.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an obstetric noninvasive membrane rupturer. 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 deliver. Color, thereby strengthening uterine contractions and accelerating the progress of labor. Most of the artificial membrane rupture tools used in the obstetrics department of the hospital are Alice forceps. In clinical operations, they are mostly carried out with the help of touch and instruments under non-direct vision. It is very inconvenient to operate with Alice forceps, and the technical proficiency requirements for doctors are relatively high. High, and the depth is difficult to grasp when the membrane is ruptured. If the penetration depth is too deep, it may damage the fetus. When the Alice forceps pass throu...

Problems solved by technology

Most of the artificial membrane rupture tools used in the obstetrics department of the hospital are Alice forceps. In clinical operations, they are mostly carried out with the help of touch and instruments under non-direct vision. It is very inconvenient to operate with Alice forceps, and the technical proficiency requirements for doctors are relatively high. High, and the depth is difficult to grasp when the membrane is ruptured. If the penetration depth is too deep, it may damage the fetus. When the Alice forceps pass through the vagina, it is easy to cause damage to the vagina, which is not safe. The Alice forceps are not easy to pinch the membranes, and the operation is difficult Large, there are failures, so there is a certain risk to the mother
