Abstract

The invention discloses a membrane rupture device. The device comprises a cylinder body, a mounting cavity is formed in the cylinder body, and a suction cup is arranged at an opening of the right endof the mounting cavity and is of a conical structure; a light reflection layer is arranged on the inner wall of the suction cup, a retractable rod is arranged in the cylinder body, and a puncture mechanism is arranged at the right end of the retractable rod; a guide sleeve slidingly sleeves the outer side of the retractable rod and is fixedly connected with the inner wall of the mounting cavity through a positioning rod, and a rotation limit mechanism is arranged between the guide sleeve and the retractable rod and comprises a limit groove formed in the inner wall of the guide sleeve and a limit protrusion located at the outer side of the retractable rod; a transmission screw hole is formed in the left end of the retractable rod. The membrane rupture device is simple and reasonable in structure, through a rotation motor, a puncture needle can pierce into through a rotation mode, and the puncture effect is improved. By adopting a mode that part of membrane is sucked in an auxiliary extrusion cylinder for puncture, the hidden safety dangers during direct puncture are avoided, the safety of the device is improved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an obstetric membrane rupturer. Background technique [0002] The obstetric rupture device is an important device to promote the progress of labor and observe the intrauterine situation in the fetus. In the past, it was generally difficult to observe the situation in the fetus, and it could only achieve rupture of the membrane. Although in recent years, devices that use cameras to observe the internal situation have begun to appear. However, the current camera has a limited shooting range, cannot realize angle adjustment, cannot observe carefully and comprehensively, and cannot provide sufficient internal conditions and information for doctors. Moreover, when the membrane is ruptured, the length adjustment of the puncture needle is unstable and limited. , it is easy to cause adverse effects on pregnant women or fetuses. At the same time, because when drawing amniotic fl...
