Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of obstetric membrane rupture devices, in particular to a clinical obstetric membrane rupture device. Background Art
[0002] In the clinical practice of obstetrics and gynecology, for parturients with weak and difficult uterine contractions during the active period, it is generally necessary to artificially puncture the amniotic membrane to help them give birth. Artificial rupture of membranes is to artificially intervene to tear the amniotic membrane at the cervical os in order to observe the color of amniotic fluid, strengthen uterine contractions and accelerate the progress of labor. Then doctors usually use vascular clamps to tear the fetal membrane, but vascular clamps are not sharp enough;
[0003] Therefore, in the actual process of rupturing the membrane, it is difficult for the doctor to control the strength during manual operation. Excessive force will cause harm to the patient and increase the difficulty of medical work. In addition, the vascular clamp needs to go deep into the patient's body. This situation is not convenient for the doctor to observe the position of the vascular clamp to perform the work, which will greatly increase the progress of the membrane rupture work. At the same time, during the penetration process, the vascular clamp will contact other parts of the patient, causing epidermal damage to the patient and causing secondary harm to the patient.

A one-way valve is arranged on the airway tube 102, and the gas inside the inflation bag 103 can be filled into the rubber plug 101 through the airway tube 102 to expand the rubber plug 101. The expanded rubber plug 101 can seal the patient's genitals to prevent the sudden outflow of amniotic fluid and affect the doctor's work.
[0030] Example 2
[0031] Reference Figure 1-4, which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: a collar 1101 fixedly connected to the tool rod 1 is arranged in the hollow cavity 11, and the collar 1101 is welded to the tool rod 1, wherein a threaded adjustment screw 1102 is arranged through the collar 1101. The adjustment screw 1102 is arranged in a T shape.
[0032] The adjusting screw 1102 is movably connected to the moving rod 13 , and the adjusting screw 1102 and the moving rod 13 are connected via a rotating shaft, wherein a guide frame 1103 fixedly connected to the device rod body 1 is arranged in the hollow cavity 11 .
