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 2 through the connecting plate 3, the connecting plate 3 is in the shape of an arc, and the connecting plate 3 has two and The symmetrical arrangement not only increases the aesthetics of the product, but also makes the fixing of the box 2 and the cylinder 1 more reliable. The box 2 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 2, on the basis of Embodiment 1, is given by Fig. 6, the clamping device of fixing column 7 is provided in described box body 2, and clamping device clamps fixed column 7 after sliding, clamps The device includes two splints 22. The splints 22 are arc-shaped structures. The arc-shaped splints 22 can clamp and lock the fixing column 7 conveniently, so that the fixing column 7 can be firmly fixed after sliding. The two splints 22 are symmetrical. Arranged at both ends of the fixed column 7, the two splints 22 move towards each other, which can quickly lock the fixed column 7. There is a rotating shaft 23 on the outside of each splint 22, and the front end and the middle part of the rotating shaft 23 Threads are provided and the direction of rotation of the threads is opposite. A rectangular block 24 is threadedly connected to the front end and the middle part of the rotating shaft 23. The inside of the rectangular block 24 is provided with internal threads. The ...

Embodiment 3

[0043] Embodiment three, on the basis of embodiment one, by figure 2 Given, the upper end of the first through hole 5 is provided with a first sealing cover, the first sealing cover seals the first through hole 5, the first sealing cover and the sealing ring 4 are hinged and fixed, and the first sealing cover is set on the hinge shaft. The torsion spring, under the torsional force of the first torsion spring, can well seal the first through hole 5, one end of the first torsion spring is fixedly connected to the hinge shaft, and the other end of the first torsion spring is connected to the first sealing cover Fixed connection.

Abstract

An artificial membrane breaker solves the problem that there is no special membrane breaker in clinic, which may lead to occupational exposure of medical staff, and may cause maternal and newborn injury. The utility model comprises a vertical cylinder, wherein the lower end of the cylinder is fixedly connected with the box body through a connecting plate; The upper end of the cylinder body is fixed with a conical sealing ring, the upper end of the sealing ring is larger than the lower end, the lower end of the cylinder body is fixed with a sealing plug, a hollow fixing column is slidably arranged in the cylinder body, the upper end face of the fixing column penetrates the sealing ring, and the lower end of the fixing column penetrates the cylinder body and is slidably connected with the box body. The fixing column is provided with a vertical sliding needle, the lower end of the needle is rotatably connected with a lead screw, the fixing column is divided into an upper column and a lower column through a step, the lead screw is threadably connected with the lower column, and the lower end of the lead screw penetrates the lower column and is fixedly connected with a second gear. A gear shaft capable of vertically sliding is arranged in the housing, and a first unidirectional gear, a second unidirectional gear, a third unidirectional gear and a fourth unidirectional gear are sequentially arranged on the gear shaft from the top to the bottom.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an artificial membrane rupturer. Background technique [0002] Artificial rupture of membranes is artificially intervening to tear the amniotic membrane before the fetal presentation, so as to observe the color of amniotic fluid, strengthen uterine contractions, and speed up the progress of labor. It is a common treatment method during natural childbirth. [0003] Procedures for artificial rupture of membranes: dilation of the cervix ≥ 3 cm, headless pelvic disproportion, fetal head connected, rule out umbilical cord prolapse and placenta previa, check vaginal cleanliness, strictly disinfect and perform vaginal examination. 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 ...
