It should be further stated that the space between the left side of the limiting plate 23 and the inner wall of the cylinder 1 is larger than the space between the connecting tube 2 and the suction cup 3, so that when the first piston 4 moves, the limiting plate 23 stops moving, the suction cup 3 and the gas in the connecting tube 2 are already sucked into the cylinder 1, and the suction cup 3 is at a negative pressure to suck the head of the fetus.

Example two

The utility model provides a fetal head attraction practise midwifery device for gynaecology and obstetrics, its on the basis of embodiment one, clearance mechanism is including fixed intercommunication at the first air duct 12 at barrel 1 top, and the fixed intercommunication of the tip of first air duct 12 has second air duct 13, and second air duct 13 is kept away from the one end of first air duct 12 and is installed toper air duct 14, and the inside of first air duct 12 is provided with first check valve 16.

When the second piston 10 moves to the left side in the cylinder 1, the first check valve 16 is opened, and when the second piston 10 moves to the right side in the cylinder 1, the first check valve 16 is closed.

The tapered air duct 14 is in a tapered structure, and one wide side of the tapered air duct is fixed with an annular plate 15, the annular plate 15 is glued with the outer side of the inner wall of the second air duct 13, and it should be noted that the tapered structure of the tapered air duct 14 is designed, so that when air passes through the tapered air duct 14, the flow rate of the air is increased.

EXAMPLE III

The utility model provides a fetal head attraction practise midwifery device for gynaecology and obstetrics, its on the basis of embodiment two, take out from the mechanism including fixed intercommunication in the third air duct 17 of barrel 1 bottom, the fixed intercommunication of the tip of third air duct 17 has fourth air duct 18, the fixed intercommunication of the bottom of sucking disc 3 has fifth air duct 20, be provided with collecting box 19 between fifth air duct 20 and the fourth air duct 18, and the tip that fifth air duct 20 and fourth air duct 18 are close to collecting box 19 all is linked together with the inside of collecting box 19, the inside of third air duct 17 is provided with second check valve 22.

It should be noted that when the second piston 10 moves to the left side in the cylinder 1, the third air duct 17 is in a closed state, and when the second piston 10 moves to the right side in the cylinder 1, the third air duct 17 is opened.

The collecting box 19 is a cylindrical structure with the top sealed and the bottom opened, the bottom of the collecting box 19 is inserted with a plug 21, the outer side of the plug 21 is attached to the inner wall of the collecting box 19, and a convex plate is fixed at the bottom of the plug 21.

In addition, the inside of two holding between the fingers board 25 all sliding connection has gag lever post 27, and threaded connection has knob 28 on holding between the fingers board 25 in two boards 25, and knob 28 runs through and supports gag lever post 27 behind holding between the fingers board 25, and the one end that connecting pipe 2 was kept away from to two gag lever posts 27 is all fixed mutually with the surface of handle 24.

The working principle is as follows: firstly, the midwife places the suction cup 3 at a proper position of the head of the fetus, holds the grip 24 to push the pull rod 11, moves the second piston 10 and the first piston 4 towards the inside of the cylinder body 1 until the first piston 4 is abutted to the inner wall of the left side of the cylinder body 1, then places the suction cup 3 on the head of the fetus, and then presses the grip 24, so that the pull rod 11 drives the second piston 10 to move, the second one-way valve 22 is closed when the second piston 10 moves, the first one-way valve 16 is opened, at this time, the gas between the first piston 4 and the second piston 10 is squeezed to the inside of the second air duct 13, because the structure of the second air duct 13 is that one end close to the first air duct 12 is wide and the other end far from the first air duct 12 is narrow, the flow rate of the gas is increased when the gas passes through the inside of the second air duct 13, the tapered structure of the tapered air duct 14 increases the flow rate of the gas again, since the fetus is born with some secretion left on the head of the fetus, which may affect the sealing performance of the suction cup 3 when the secretion is left between the head of the fetus and the suction cup 3, the secretion between the suction cup 3 and the head of the fetus can be cleaned by the air blown out through the tapered air duct 14 when the suction cup 3 is placed on the head of the fetus.

After the pressing, the handle 24 is loosened, under the action of the resilience force of the elastic piece 9, the second piston 10 moves to the right, the first one-way valve 16 is closed at the moment, the second one-way valve 22 is opened, the gas in the fifth air duct 20, the collecting box 19 and the fourth air duct 18 is respectively sucked into the cylinder body 1, so that the collecting box 19 is in a negative pressure state, at the moment, the collecting box 19 can absorb the mucus at the bottom of the sucker 3 into the collecting box 19 through the fifth air duct 20, the influence of the existence of the mucus on the suction force of the sucker 3 is avoided, then the handle 24 is pulled, so that the pull rod 11 drives the second piston 10 and the first piston 4 to move, the cylinder body 1 is pumped into a negative pressure when the first piston 4 moves, the negative pressure condition in the cylinder body 1 is controlled through observation 26, when the sucker 3 sucks the head of the fetus, the knob 28 is rotated, so that the knob 28 abuts against the limiting rod 27, and the negative pressure in the cylinder body 1 is stably stored, then the device is pulled to carry out midwifery.

Exemplary embodiments of the proposed solution of the present disclosure have been described in detail above with reference to preferred embodiments, however, it will be understood by those skilled in the art that many variations and modifications may be made to the specific embodiments described above, and that many combinations of the various technical features and structures presented in the present disclosure may be made without departing from the concept of the present disclosure, without departing from the scope of the present disclosure, which is defined by the appended claims.
