Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

The cylinder comprises a cylinder 1 with an upward opening, a square frame 2 is arranged at the upper end of the cylinder 1, trapezoidal plates 3 are hinged to each side wall of the square frame 2, the trapezoidal plates 3 can form a square-shaped structure, a puncture needle 4 is arranged at the inner end of each trapezoidal plate 3, a piston 5 is coaxially and slidably connected to the inner side of the cylinder 1, a cylindrical rod 6 penetrating through the cylinder 1 is coaxially arranged at the lower end of the piston 5, a plurality of connecting rods 7 which are vertically hinged to the upper end of the piston 5 and correspond to the trapezoidal plates 3 one to one, and the free ends of the connecting rods 7 are respectively hinged to the trapezoidal plates 3 on the corresponding side.

In order to reset the plurality of puncture needles 4, a circular plate 8 positioned in the cylinder 1 is coaxially arranged on the cylindrical rod 6, and a tension spring 9 positioned between the circular plate 8 and the cylinder 1 is sleeved on the outer edge surface of the cylindrical rod 6.

In order to prevent the cylindrical rod 6 from rotating during film rupture, the lower side wall of the cylinder 1 is provided with a plurality of chutes 10 which are uniformly distributed along the circumferential direction and run through from top to bottom, the outer edge surface of the cylindrical rod 6 is provided with a plurality of guide rails 11 which are in one-to-one correspondence with the chutes 10, and the guide rails 11 can respectively slide in the chutes 10 on the corresponding sides.

In order to prevent the neonate from being punctured by the plurality of puncture needles 4, the upper end of the cylinder 1 is provided with a bowl-shaped plate 12 with an opening facing upwards, and each puncture needle 4 can extend out of the bowl-shaped plate 12.

In order to facilitate the pushing of the cylindrical rod 6, a push plate 13 is coaxially arranged at the lower end of the cylindrical rod 6.

For the convenience of medical staff, the front and back sides of the lower end of the cylinder 1 are respectively provided with a front and back fixing plate 14.

When the utility model is used, the device is firstly arranged in an initial state that the trapezoidal plates 3 form a shape like a Chinese character 'hui', the medical staff holds the cylinder 1 by hand and inserts the bowl-shaped plate 12 into the birth canal of a puerpera until the upper end of the bowl-shaped plate 12 is inserted from the uterine orifice of the puerpera and contacts with the amnion, the cylinder 1 is kept still, the medical staff needs to hook the two fixing plates 14 by two fingers and then push the push plate 13 by the palm upwards;

the push plate 13 drives the cylindrical rod 6 to move upwards, the cylindrical rod 6 drives the guide rails 11 to slide upwards in the sliding groove 10, meanwhile, the cylindrical rod 6 drives the circular plate 8 to move upwards in the cylinder 1, the circular plate 8 stretches the tension spring 9 upwards, the cylindrical rod 6 drives the piston 5 to slide upwards in the cylinder 1, the piston 5 drives the connecting rods 7 to move upwards, the connecting rods 7 respectively drive the trapezoidal plates 3 on the corresponding sides to swing upwards in the frame 2, the trapezoidal plates 3 respectively drive the puncture needles 4 on the inner ends to swing upwards, the puncture needles 4 gradually swing upwards and are in contact with the amnion, the push plate 13 is continuously pushed upwards, the puncture needles 4 scratch the amnion, artificial membrane rupture is realized, and the bowl-shaped plate 12 can prevent the puncture needles 4 from penetrating into the amnion to too deep depth, so that a newborn is prevented from being punctured by the puncture needles 4;

after the membrane rupture is finished, firstly, the push plate 13 is loosened, the tension spring 9 starts to pull the circular plate 8 to move downwards, the circular plate 8 drives the cylindrical rod 6 to move downwards, the cylindrical rod 6 drives the piston 5 to slide downwards in the cylinder 1, the piston 5 drives the connecting rods 7 to move downwards, the connecting rods 7 respectively drive the trapezoidal plates 3 on the corresponding sides to swing downwards, the trapezoidal plates 3 respectively drive the puncture needles 4 on the inner ends to swing downwards, finally, the trapezoidal plates 3 form a shape like a Chinese character hui again, and then the cylinder 1 is held by hand to pull out the device from the body of a lying-in woman.
