Anti-flow-out type membrane breaking device in Department of Gynecology and Obstetrics

Abstract

The invention discloses an anti-flow-out type membrane breaking device in the Department of Gynecology and Obstetrics, and belongs to the field of medical equipment. The device includes a puncture cylinder body and a liquid storage device, the side wall of a suction mouth of the puncture cylinder body is provided with a ring-shaped bottom plate, horizontal baffle plates, vertical baffle plates and rotatable pressing plates, so that at least four first through openings and second through openings are formed at the peripheral side of suction mouth, located between the side wall of the suction mouth and the rotatable pressing plates, and the rotatable pressing plates are rotatable; the top of the liquid storage device is connected to two suction chambers capable of carrying out suction actions alternately, the two suction chambers are separately equipped with a injection-push piston, the top of each injection-push piston is connected with a driving rod through a short rod hinged at both ends, and the free end of the second driving rod is fixedly connected with a handle rod; and the lower side of the handle rod is longitudinally penetrated with a bolt, and the top of the bolt is fixed with a limit plate. The invention is capable of effectively preventing amniotic fluid from flowing out without the participation of electric energy and continuously generating negative pressure, high in suction efficiency, good in uniformity of force application of a negative pressure generating mechanism, relatively high in control precision and relatively good in controllability of suction rate.

Description

technical field [0001] The invention relates to the field of medical devices, 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 and drains the amniotic fluid. Traditionally, the membrane rupture device used is generally in the form of a simple infusion needle, which not only has the risk of harming the fetus and the mother, but also pollutes the operating environment due to amniotic fluid outflow, which brings great inconvenience to the medical staff. [0003] At present, an anti-outflow membrane rupture device has been developed in the prior art. For example, an obstetrics and gynecology anti-outflow membrane rupture device is disclosed in a patent with the authorized announcement number CN1...

AI Technical Summary

Problems solved by technology

This negative pressure generation method has the following disadvantages: during the deflation process of the airbag, no suction effect is produced on the liquid reservoir, and the flow of amniotic fluid into the liquid reservoir will weaken the negative pressure effect in the liquid reservoir, making the liquid s
