Embodiment 1

[0033] Embodiment one, by Figure 1-3 Given, the present invention includes a vertical cylinder 1, the cylinder 1 is cylindrical, the lower end of the cylinder 1 is fixedly connected with the box 3 through the connecting plate 2, the connecting plate 2 is in the shape of an arc, and the connecting plate 2 has two and The symmetrical arrangement not only increases the aesthetics of the product, but also makes the fixing of the box 3 and the cylinder 1 more reliable. The box 3 can be square or round, which is represented by a square in this product;

[0034] The upper end of the cylinder body 1 is fixed with a tapered sealing ring 4, the upper end of the sealing ring 4 is larger than the lower end, and the upper end surface of the sealing ring 4 is a smooth surface, which is convenient for the sealing ring 4 to contact with the placenta of the puerpera. It is a large mouth, which is convenient for the membrane to enter the sealing ring 4. The lower end of the cylinder body 1 is ...

Embodiment 2

[0042] Embodiment two, on the basis of embodiment one, by Figure 5 Given, the box body 3 is provided with a clamping device for the fixed column 8, the clamping device clamps the fixed column 8 after sliding, the clamping device includes two clamping plates 23, and the clamping plates 23 are arc-shaped structures, The curved splint 23 can clamp and lock the fixed column 8 conveniently, so that the fixed column 8 is firmly fixed after sliding. The two splints 23 are symmetrically arranged at both ends of the fixed column 8, and the two splints 23 are opposite The movement of the fixed column 8 can be quickly locked and locked. A rotating shaft 24 is provided on the outside of each splint 23. The front end and the middle part of the rotating shaft 24 are provided with threads and the screw threads are in the opposite direction. The front end and the middle of the rotating shaft 24 Parts are connected with a rectangular block 25 which is threaded. The inside of the rectangular b...

Embodiment 3

[0043] Embodiment 3, on the basis of Embodiment 1, the upper end of the first through hole 6 is provided with a first sealing cover, the first sealing cover seals the first through hole 6, and the first sealing cover is hinged to the sealing ring 4 Fixed and the first torsion spring is set on the hinge shaft, under the action of the torsion force of the first torsion spring, the first through hole 6 can be well sealed, one end of the first torsion spring is fixedly connected with the hinge shaft, the first torsion The other end of the spring is fixedly connected with the first sealing cover.

Abstract

A new type of artificial membrane rupture device, which solves the problem that there is no special membrane rupture tool in clinical practice, which leads to easy occupational exposure during membrane rupture, which is not conducive to the safety of puerpera and fetus. It includes a vertical cylinder, and the lower end of the cylinder The box is fixedly connected with the connecting plate; the upper end of the cylinder is fixed with a tapered sealing ring, the upper end of the sealing ring is larger than the lower end, the lower end of the cylinder is fixed with a sealing plug, and the cylinder is slidably provided with a hollow fixed column to fix The upper end of the column runs through the sealing ring, and the lower end of the fixed column runs through the cylinder and is slidingly connected with the box; the cylinder is equipped with a vertically sliding piston, and the lower end of the piston is rotatably connected to a hollow threaded rod, and the lower end of the threaded rod passes through the sealing plug and is connected with the The sealing plug is threaded. The lower end of the threaded rod is placed in the box and is fixedly connected with the first idler. The first gear is fixed on the threaded rod above the first idler. It can slide vertically inside, and the lower end of the fixed column runs through the threaded rod.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel artificial membrane rupture device. Background technique [0002] Artificial membrane rupture is one of the common medical interventions used in obstetrics to promote the labor process. At present, the most commonly used clinical operations are puncture needles and hemostatic forceps. In clinical operations, the surgical steps of artificial membrane rupture: dilation of the cervix ≥ 3cm , No head-pelvis disproportion, fetal head has been connected, umbilical cord prolapse and placenta previa are excluded, vaginal cleanliness is checked, and vaginal examination is performed under strict disinfection. Between two uterine contractions, insert the left middle and index finger into the vagina for guidance, and hold the toothed forceps in the right hand. The amniotic fluid will flow out after the forceps break the membranes, and the fetal heart can be heard after th...
