Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
Example one
As shown in figure 1, a membrane rupturing device for obstetrical department comprises a sleeve 1, the left end and the right end of the sleeve 1 are arranged in an open manner, a baffle 2 is integrally formed on the inner wall of the front end of the sleeve 1, the baffle 2 is arc-shaped, a membrane rupturing needle perforation 3 and a liquid leading hole 4 penetrating through the baffle 2 are processed on the baffle 2, the membrane rupturing needle perforation 3 is positioned in the center of the baffle 2, the liquid leading holes 4 are uniformly distributed on the baffle 2, a piston 5 is arranged in the sleeve 1, one end of the piston 5, which is back to the baffle 2, is connected with a push rod 6, a threaded hole 7 is formed in the push rod 6 in a penetrating manner along the central axis of the push rod 6, a membrane rupturing needle adjusting rod 8 is screwed in the threaded hole 7, one end part, far away from the piston 5, of the membrane rupturing needle adjusting rod 8 is exposed out of the sleeve 1, a scale line 9 is processed on the membrane rupturing needle adjusting rod 8 exposed out of the sleeve 1, the inner wall laminating of rupture of membranes needle mount pad 11 and round hole 10, and the cover has rubber seal cover 12 on the rupture of membranes needle mount pad 11 periphery wall, rupture of membranes needle mount pad 11 and rupture of membranes needle regulation pole 8 integrated into one piece, processing has rupture of membranes needle mounting hole on the rupture of membranes needle mount pad 11, rupture of membranes needle 13 fixed mounting is in rupture of membranes needle mounting hole, screw hole 7, the 3 three coaxial lines of round hole 10 and rupture of membranes needle perforation, through screw thread regulation rupture of membranes needle regulation pole 8, make rupture of membranes needle 13 make a round trip to stretch out and draw back on the route that round hole 10 and rupture of membranes needle perforation 3 formed.
When the utility model works, firstly, the piston 5 is pressed to be in contact with the baffle 2, then the sleeve 1 is stretched into the vagina to enable the front end of the sleeve 1 to be in contact with the amnion, then the piston is slowly pulled backwards, under the action of negative pressure, the amnion is sucked by the sleeve and is attached on the baffle 2, because the baffle 2 is arc-shaped, the amnion is more favorably attached, at the moment, the membrane breaking needle adjusting rod 8 is slowly rotated to enable the membrane breaking needle 13 to slowly stretch out, the stretching length of the membrane breaking needle can be accurately controlled by observing the screwed scale mark, thereby reducing the operation risk, after the membrane breaking succeeds, the membrane breaking needle adjusting rod 8 is adjusted to enable the membrane breaking needle 13 to withdraw into the round hole 10, thereby avoiding the secondary injury caused by the membrane breaking needle 13, after the membrane breaking succeeds, the piston 5 is continuously pulled backwards, the amniotic fluid can enter the cylinder body from the fluid introduction hole 4 to complete the drainage, because the rubber sealing sleeve 12 is sleeved on the, thereby preventing leakage of amniotic fluid.
