An anti-outflow membrane rupture device for obstetrics and gynecology

Abstract

The invention discloses an obstetrics and gynecology anti-outflow membrane rupture device, belonging to the field of medical appliances, comprising an injection cylinder with a cone head connected to the front end, an injection piston is arranged in the injection cylinder, and the side where one end of the injection cylinder is connected to the cone head is fixed. There is a puncture needle extending to the side where the front port of the cone head is located; the outer surface of the front end of the cone head is fixed with an arched cover plate to form an annular cavity, the front port of the ring cavity surrounds the front port of the cone head in a ring shape, and the annular cavity is connected to the inside of the cone head through the air vent; There are at least three rotating rods along the circumference of the annular chamber. The front end of the rotating rod is located at the front port of the annular chamber and attached to the cover plate. The rear end of the rotating rod is hinged on the side wall of the rear end of the annular chamber. An electromagnet that magnetically attracts the permanent magnet is built in the side wall of the front port of the cone head; a drainage tube is provided on one side of the rear end of the cone head. The invention does not cause damage to the fetus and the capsule during the membrane rupture process, and can fix the puncture opening formed after the membrane rupture in time, thereby avoiding position changes of the puncture opening and effectively preventing amniotic fluid outflow.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an obstetrics and gynecology anti-outflow membrane rupture device. Background technique [0002] In obstetrics and gynecology, the amniotic fluid capsule will usually rupture naturally before giving birth to release the amniotic fluid so that the fetus can be delivered smoothly. The medical staff punctures the capsule to drain the amniotic fluid, but the currently used membrane rupture devices are generally in the form of simple infusion needles, which poses the risk of harming the fetus and the mother, and also pollutes the surgical environment due to the outflow of amniotic fluid, which brings great harm to the medical staff. It's a big inconvenience. [0003] In the patent application publication number CN 105596062 A, an obstetrics and gynecology anti-outflow membrane rupture device is disclosed, which includes a catheter, one end of the catheter is covered with a pull rod,...

Problems solved by technology

However, it has the following disadvantages: after the amniotic fluid capsule is punctured, during the drainage process, due to the instability of the amniotic fluid capsule structure, once the amniotic fluid capsule shifts and fluctuates, it will easily lead to changes in the position of the puncture port. The contact between the surrounding area and the amniotic fluid capsule is also unstable, which will still lead to the outflow of amniotic fluid
