Adjustable safe membrane-rupturing device for obstetrics and gynecology department

Abstract

The invention discloses an adjustable safe membrane-rupturing device for an obstetrics and gynecology department, and belongs to the technical field of medical treatment instruments. The adjustable safe membrane-rupturing device mainly comprises a cavity main body, a membrane-rupturing element, a liquid-collecting element and a power supply, wherein the membrane-rupturing element comprises a cleanmounting panel, a membrane-rupturing needle and a vagina-expanding adjusting cover, the vagina-expanding adjusting cover comprises a plurality of expansion plates, folding inflation covers and a miniature inflation pump, and each folding inflation cover is arranged between two adjacent expansion plates. Each folding inflation cover is in a folding state before a membrane-rupturing operation of the vagina-expanding adjusting cover, so that the whole vagina-expanding adjusting cover is relatively small in size, the membrane-rupturing element can be advantageously put into a foetal membrane, andmeanwhile, an vaginal orifice of a pregnant woman is not injured; and when the vagina-expanding adjusting cover enters the foetal membrane, the folding inflation covers are inflated, the whole vagina-expanding adjusting cover is opened to be fit with the foetal membrane, amniotic fluid flowing out of the foetal membrane after the membrane-rupturing operation is pumped into a fluid-collecting element from the vagina-expanding adjusting cover through a negative pressure, so that the operations of the whole process are simple, a fetus and the pregnant woman are not injured, and meanwhile, the situation that the amniotic fluid flows out to pollute an operation environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an adjustable safety membrane rupture device for obstetrics and gynecology. Background technique [0002] Amniotic fluid is the liquid that fills the amniotic cavity. Amniotic fluid can provide the fetus with a large range of activities, so that the fetus can perform appropriate breathing exercises and physical activities in the official cavity, and prevent joint fixation, limb deformities and fetal limb adhesions, which is conducive to the development of the fetus. Development can also balance external pressure and reduce the impact of external violence, thereby protecting the fetus. [0003] 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 method helps to produce, and at this time, medical personnel need to puncture the c...

AI Technical Summary

Problems solved by technology

[0004] The existing membrane rupture device has the following defects: 1) before and during membrane rupture, the size of the membrane rupture element cannot be changed depending on the situation. On the one hand, it is easy to cause damage to the vaginal opening of pregnant women; The components cannot be attached to the fetal membranes, which may easily cause amniotic fluid outflow and pollute the surgical environment; 2) The extracted amniotic fluid cannot be filtered, so that the tissue components in the amniotic fluid will block the pipeline, affecting the normal operation of the amniotic fluid collection equipment and affecting the operation of the entire device 3) The degree of intelligence is low, and the amount of amniotic fluid extracted cannot be visually observed, so the reliability is low
