Obstetrics and gynecology anti-outflow type membrane breaking device

Abstract

The invention discloses an obstetrics and gynecology anti-outflow type membrane breaking device, and belongs to the field of medical instruments. The device comprises a syringe barrel with a cone headconnected to the front end, a push injection piston is arranged in the syringe barrel, and the side of the end, connected with the cone head, of the syringe barrel is fixed to a puncture needle extending to the side of the front end opening of the cone head; the outer surface of the front end of the cone head is fixed to an arched cover plate to form an annular cavity, a front end port of the annular cavity is annular around the front end opening of the cone head, and the annular cavity is communicated with the inner side of the cone head through a vent; at least three rotating rods are arranged in the annular cavity along the circumference of the annular cavity, the front ends of the rotating rods are located at the front end opening of the annular cavity and are attached to the cover plate, the rear ends of the rotating rods are hinged to the rear end side wall of the annular cavity, permanent magnets are built in the front ends of the rotating rods, and electromagnets magneticallysucked to the permanent magnets are built in the side wall of the front end opening of the cone head; a drain tube is arranged at one side of the rear end of the cone head. The device does not damagefetuses and capsules during the membrane rupture process, can fix a puncture mouth formed after the rupture of the membrane in time, can avoid the positional change of the puncture mouth, and effectively prevents the outflow of amniotic fluid.

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,...

AI Technical Summary

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
