An obstetric membrane rupturer

Abstract

The invention provides a membrane rupture device for the obstetrical department. The membrane rupture device comprises a suction cup, a cylinder on the suction cup, a puncture needle, a camera, a connection line, a display, a cylinder body, a piston, a piston rod and a disc-shaped nut. The angle of the camera is adjustable. The disc-shaped nut is matched with an outer thread on the piston rod, so that the moving speed of the piston rod can be evenly adjusted by evenly rotating the disc-shaped nut. According to the membrane rupture device, the length of the puncture needle is adjusted through a thread, the length by which the puncture needle stretches in can be increased, and the membrane rupture reliability is improved; the angle of the camera can be adjusted so that a doctor can know the situation in an embryo comprehensively from different angles and provide useful information for giving birth of pregnant women; hinge joint in match with the thread is adopted, the reliability of camera adjustment can be improved, and adjustment is very convenient to conduct; the disc-shaped nut is adopted to adjust the moving speed of the piston rod, the moving uniformity of the piston can be improved, the pain of the pregnant women can be reduced, the safety of fetuses is improved, and the operation difficulty of doctors is lowered.

Description

technical field [0001] The invention relates to the technical field of medical devices, 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 flui...

[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 fluid, only relying on manual suction and manually pushing the translation of the piston rod will easily lead to uneven suction speed and aggravate pain of pregnant women. The operability requirements for doctors High, difficult to meet modern needs
