Description

Technical Field

[0001] This utility model belongs to the field of membrane rupture device technology, and specifically relates to a membrane rupture device for obstetric delivery rooms. Background Technology

[0002] Artificial rupture of membranes, also known as rupture of membranes, is a procedure performed in the maternity ward. It involves manually tearing the amniotic membrane at the cervix using instruments to observe the color of the amniotic fluid, strengthen uterine contractions, and accelerate the progress of labor. It is a common method of inducing labor during natural childbirth.

[0003] Currently, some amniocentesis devices rupture the amniotic sac by puncturing the amniotic membrane of pregnant women with a rupture needle. During use, manual pushing force is often required to rupture the membrane directly. There is no buffering function during the rupture process. Due to the different experience of medical staff, uneven force can easily occur during rupture, resulting in unsuccessful rupture or excessive force, which may cause safety hazards. In addition, most amniocentesis devices are integrated and fixed structures, which are not convenient for length adjustment and have limited use. Utility Model Content

[0004] The purpose of this utility model is to provide a membrane rupture device specifically for obstetric delivery rooms. Its advantages are that it allows the membrane rupture needle to advance slowly and makes it easy to adjust the length of the membrane rupture device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a membrane rupture device for obstetric delivery rooms, comprising a fixed cylinder, a membrane rupture needle and a protective sleeve fixedly connected to one side of the fixed cylinder, the membrane rupture needle being located inside the protective sleeve, a first spring being provided on the outer side of the membrane rupture needle, a through hole being provided at the center of one side of the protective sleeve, a telescopic rod being slidably connected inside the fixed cylinder, a hand-held part being fixedly connected to one end of the telescopic rod, and a fixing component being provided inside the telescopic rod.

[0006] The above technical solution involves inserting the fixing cylinder into the pregnant woman's vagina and ensuring the protective sleeve adheres to the amniotic sac. Then, a pushing force is applied to the fixing cylinder, compressing the protective sleeve and the first spring. The membrane rupture needle slowly emerges from the through-hole and punctures the amniotic sac, preventing uneven force from causing the membrane rupture needle to penetrate too deeply. When the length of the membrane rupture device needs to be adjusted, the restriction on the telescopic rod is released through the fixing mechanism. Then, the handle is pulled to move the telescopic rod, and the telescopic rod is fixed by the automatic reset of the fixing mechanism.

[0007] The present invention is further configured such that: the inner wall of the protective sleeve is provided with a through groove, and the through groove is connected to the through hole.

[0008] The above technical solution facilitates the outflow of amniotic fluid from inside the protective cover, making it easier for medical staff to observe.

[0009] The present invention is further configured such that one end of the first spring is fixedly connected to one side of the fixed cylinder, and the other end of the first spring is fixedly connected to the inner wall of the protective sleeve.

[0010] The above technical solution facilitates the stabilization of the first spring.

[0011] The present invention is further configured such that the inner wall of the handheld part is provided with a groove, and an anti-slip sleeve is provided on the outer side of the groove.

[0012] The above technical solution makes it easier for medical staff to hold the membrane rupture device.

[0013] The present invention is further configured such that the fixing component includes a positioning hole opened on the outside of the fixing cylinder, a positioning pin is provided on the inner wall of the positioning hole, a connecting plate is fixedly connected to the bottom of the positioning pin through the inner wall of the telescopic rod, and a second spring is fixedly connected to the bottom of the connecting plate.

[0014] The above technical solution facilitates the fixing of the telescopic pole.

[0015] The present invention is further configured such that a guide rod is slidably connected to the inner wall of the connecting plate, and one end of the guide rod is fixedly connected to the inner wall of the telescopic rod.

[0016] The above technical solution facilitates stable movement of the connecting plate.

[0017] The present invention is further configured such that the number of positioning holes is several, and the several positioning holes are equally spaced.

[0018] The above technical solution facilitates the adjustment of the position of the telescopic rod.

[0019] The present invention is further configured such that a directional block is fixedly connected to the outer side of the telescopic rod, and the outer side of the directional block is slidably connected to the inner wall of the fixed cylinder.

[0020] The above technical solution facilitates stable movement of the telescopic pole and prevents it from deflecting.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. Insert the fixing tube into the pregnant woman's vagina and make the protective sleeve fit the amniotic sac. Then continue to apply pushing force to the fixing tube. At this time, the protective sleeve and the first spring are compressed, and the amniotic sac rupture needle slowly emerges from the through hole and punctures the amniotic sac. Avoid uneven force application that may cause the amniotic sac rupture needle to penetrate too deeply.

[0023] 2: When the length of the film rupturer needs to be adjusted, the restriction on the telescopic rod is released through the fixing mechanism, then the hand handle is pulled to move the telescopic rod, and the telescopic rod is fixed by the automatic reset of the fixing mechanism.
