Membrane rupturing device for gynaecology and obstetrics

Abstract

The invention discloses a membrane rupturing device for gynaecology and obstetrics. One end of a cylinder body is communicated with a pipe body, two second plate bodies are symmetrically and fixedly connected to the outer side wall of the cylinder body, first threaded through holes are formed in one sides of the two second plate bodies correspondingly, first screws are in threaded connection withthe interiors of the first threaded through holes, and first knobs are welded to one sides of the first screws. When the cylinder body is placed in the body of a patient, by rotating the first knobs,the first screws drive a first plate body to get close to the skin surface of the patient, the first plate body is tightly attached to the skin surface of the patient, therefore the cylinder body is fixed, the phenomenon that when a doctor uses the device for membrane rupture, the hand shakes, and consequently a punctured part is inaccurate is avoided, a second knob is rotated to drive a fourth plate body and an membrane rupturing needle to slide in the cylinder body to puncture an amniotic membrane, amniotic fluid flows into the cylinder body after amniotic membrane puncture, the phenomenon that the amniotic membrane is sucked into the cylinder body to be torn to cause discomfort of the patient is avoided, and the membrane rupturing efficiency of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a membrane rupture device for obstetrics and gynecology. Background technique [0002] As we all know, obstetrics is a medical science related to the whole process of women's pregnancy, childbirth and puerperium, and to diagnose and deal with all the physiological, psychological and pathological changes that occur during the process. It is a science to assist the birth of new life. Generally, in the third trimester of pregnancy, as the fetus matures, the strong uterine contraction will rupture the amniotic membrane, and manual puncture is not necessary. Artificial rupture of membranes is only required at necessary moments such as stagnation of labor process and induction of labor in expired pregnancy. Artificial rupture of membranes, also known as artificial rupture of water, is a method used to promote the labor process. Artificial rupture of membranes is suitable for ac...

Problems solved by technology

[0004] When the device is used to rupture the amnion, hold the cylinder. If the doctor’s hand shakes, the insertion site will be inaccurate when the rupture needle punctures the amniotic membrane, which will easily cause harm to the patient’s body. When the device is fixed on the surface of the amniotic membrane and pulled The piston absorbs the amniotic membrane to the inside of the device by generating negative pressure inside the cylinder, which will cause the tearing of the amniotic membrane. Therefore, an obstetrics and gynecology rupture device is proposed.
