Flowing-out-preventing type membrane rupture device for gynecology and obstetrics department

Abstract

The invention discloses a flowing-out-preventing type membrane rupture device for the gynecology and obstetrics department and belongs to the field of medical instruments. The flowing-out-preventing type membrane rupture device comprises a syringe and is characterized in that a conical head is connected to the front end of the syringe, a push piston is arranged in the syringe, a straight tube section is formed at the front port of the conical head, and the tip of a puncture needle fixed at the front end of the syringe extends into the straight tube section; a conical cover is fixed to the tipof the puncture needle, a permanent magnetic ring component which can expand and contract sleeves the puncture needle, the permanent magnetic ring component is connected to the rear end of the conicalcover, and the periphery of the permanent magnetic ring component in the initial state is in alignment with the periphery of the rear end of the conical cover; at least three permanent magnets whichare annularly distributed in an equal-interval manner are arranged in the permanent magnetic ring component, and positions, corresponding to the permanent magnets, inside the straight tube section areprovided with electronic magnets which can attract the permanent magnets; a drainage tube is connected to one side of the rear end of the conical head. The flowing-out-preventing type membrane rupture device cannot damage the fetus and the membrane during membrane rupture, can timely fix a puncture opening formed after the membrane rupture to prevent puncture opening position change and can efficiently prevent the amniotic fluid from flowing out.

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
