when a medical staff performs midwifery, the upper end of the connecting rod 1 is inserted into the delivery canal, so that the annular shaping bag 2 is contacted with the head of a fetus, then the annular shaping bag is inflated from the first air pipe 21 to gradually expand and expand the diameter of the annular shaping bag, and then negative pressure is generated on the adsorption hole 222 through the second air pipe 5, so that the annular shaping bag 2 is adsorbed and fixed on the head of the fetus;
before the annular shaping bag 2 is not inflated, the diameter of the annular shaping bag 2 is relatively small, when the annular shaping bag 2 is inflated, the diameter of the annular shaping bag 2 is changed, and the fetal heads with different sizes are adapted;
after the annular shaping bag 2 contacts the fetal head, the medical staff can judge in time that the annular shaping bag 2 has contacted the fetal head so as to stop pushing the connecting rod 1 through the damping sense when the elastic rod 4 moves in the sliding hole 111 along with the pushing of the connecting rod 1 into the birth canal by the medical staff;
dividing the adsorption holes 222 into a plurality of groups, and enabling each group of adsorption holes 222 to be communicated with one second air pipe 5, so that negative pressure air sources are independently supplied to each group of adsorption holes 222;
in the midwifery process, medical staff can tighten the adjusting ropes 6 at the corresponding positions on the annular shaping bag 2 according to the position and the angle of the fetal head in the birth canal, so that the position and the angle of the annular shaping bag 2 are changed relative to the connecting rod 1, and the annular shaping bag 2 can be opposite to the fetal head;
meanwhile, when the adjusting rope is contracted, the medical staff firstly loosens the clamping block 61 corresponding to the adjusting rope on the lower end of the connecting rod 1, and after the adjusting rope is tightened or loosened and the position of the annular shaping bag 2 is adjusted, the clamping block 61 is clamped on the lower end of the connecting rod 1 again;
because the umbrella-shaped membrane 3 is relatively soft and airtight, after the annular shaping sac 2 is attached to the fetal head and the adsorption holes 222 are adsorbed on the fetal head, medical staff adjusts an external negative pressure air source again, negative pressure is generated in the space formed by the annular shaping sac 2 and the umbrella-shaped membrane 3 through the air pipe III 7, and therefore the space formed by the annular shaping sac 2 and the umbrella-shaped membrane 3 has the sucking disc effect;
the attaching layer 22 is prepared by using the medical silica gel material with good softness, so that the annular shaping bag 2 can be fully attached to the head of a fetus after contacting the head of the fetus, and the gap between the area near the adsorption hole 222 on the annular shaping bag 2 and the head of the fetus is reduced;
when the annular shaping bag 2 contacts the head of the fetus, the attaching layer 22 is clung to the head of the fetus under the thrust of medical staff and the negative pressure attractive force of the adsorption hole 222, and in the process, secretion existing on the head of the fetus enters the annular groove 221 on the attaching layer 22 under extrusion to collect and hold excessive secretion;
the pressure applied to the fetal head and the annular shaping bag 2 on the midwifery device is stable and controllable through the pressure valve;
when the suction cup formed by the umbrella-shaped membrane 3 attracts and pulls the fetus through the indentation formed on the inner wall of the umbrella-shaped membrane 3, secretion on the inner area of the umbrella-shaped membrane 3 on the head of the fetus can move through the space formed by the indentation and then is extracted by the air tube III 7 with negative pressure.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
