The opening and closing of the second exhaust pipe 22 can be controlled by manually opening and closing the control valve 25. The second exhaust duct 22 can be opened by the control valve 25 to allow rapid deflation of the bladder 10, allowing the pregnant woman to quickly take off the discomfort of the abdominal compression belt 11.

Example 3

Embodiment 3 differs from embodiment 1 in that, referring to fig. 14, the mounting base 17 is in the form of a flexible cloth. Both ends of the mounting bottom 17 penetrate through the accommodating cavity. The mounting base 17 is generally H-shaped. The abdominal pressure belt 11 is provided with a driving mechanism 39 for driving the mounting base 17 to slide in the width direction of the abdominal pressure belt 11. The driving mechanism 39 includes a take-up roller 37 and a driving motor 38 for driving the take-up roller 37 to rotate, and the take-up roller 37 is rotatably connected to the side of the rear tape 14 facing away from the front tape 13. Both ends of the mounting bottom 17 are wound on the winding roller 37.

After the abdominal pressure belt 11 is tied to the abdomen of the parturient, the mounting base 17 can be driven to move by the rotation of the wind-up roller 37, so that the air bag 10 can be finely adjusted to a very suitable position. Then, the air bag 10 is aerated, so that the air bag 10 can be correctly aligned with the position of the uterus for midwifery. Meanwhile, after the production process is carried out to a certain degree, the air bag 10 can also provide a thrust for the uterus by rotating the winding roller 37, so that the labor force is increased, and the delivery of the baby is facilitated.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
