Amniotic membrane breaking mechanism for obstetrical department

Abstract

The invention relates to the technical field of medical equipment for an obstetrical department, in particular to an amniotic membrane breaking mechanism for the obstetrical department. The amniotic membrane breaking mechanism comprises a fixing tube, a latex tube and a pricking needle, wherein the latex tube is arranged at one end of the fixing tube, sliding grooves are formed in inner walls of two sides of the fixing tube, pulleys are connected in the sliding grooves in a sliding manner and mounted and fixed on upper and lower sides of a moving frame, a nut pair is arranged at one end of themoving frame and connected with a lead screw in a screw drive fit manner, the pricking needle is fixed and mounted at the other end of the moving frame and located in the latex tube, one end of the lead screw is inserted and fixed in the middle of a gear clamped and fixed in a rotating ring, a fixing ring and a fixing block are glidingly connected with inner walls of two sides of the rotating ring respectively, the fixing ring is mounted and fixed at one end of the fixing tube, the lead screw is inserted and mounted in the middle of the fixing block, and a handle is mounted and fixed in the middle of one side of the fixing block, so that amniotic membranes can be pierced more efficiently and safely.

Description

technical field [0001] The invention relates to the technical field of obstetric medical devices, in particular to an obstetric amniotic membrane breaking mechanism. Background technique [0002] During the delivery process of pregnant women, it is sometimes necessary to manually rupture the membranes. On the one hand, it can speed up the progress of the labor process, and on the other hand, it can help medical staff to judge whether the fetus has intrauterine hypoxia by observing the properties of the amniotic fluid. At present, doctors or midwifery nurses mainly use leather forceps or injection needle tip to rupture the membrane. Needle tip membrane rupture requires high technical requirements for medical staff. Since they cannot see directly, they only operate with the feeling of their fingers. It may cause damage to the mother and fetus, especially when the amniotic fluid is low and the amniotic sac is not obvious. Because the traditional method cannot accurately control...

Problems solved by technology

At present, doctors or midwifery nurses mainly use leather forceps or injection needle tip to rupture the membrane. Needle tip membrane rupture requires high technical requirements for medical staff. Since they cannot see directly, they only operate with the feeling of their fingers. It may cause damage to the mother and fetus, especially when the amniotic fluid is low and the amniotic sac is not obvious. Because the traditional method cannot accurately control the depth of the needle, it is easy to cause damage to the fetal facial soft tissue, scalp, and even important organs such as the eyeball. etc. damage
