Example 1

Please refer to FIG. 1-FIG. 5. This embodiment provides a vacuum suction obstetrics and gynecology delivery device, including a suction cup 1. In order to perform vacuum suction, a ventilation tube 2 is provided on one side of the suction cup 1, and the air intake of the ventilation tube 2 is provided. The port is connected with the air outlet of the suction cup 1, and the air outlet of the ventilation pipe 2 is connected with the air inlet of the negative pressure pump 7. In order to reduce the traction resistance during traction, one end of the ventilation pipe 2 is covered with a first pipe body 3. The first pipe One end of the body 3 is fixedly connected to one side of the suction cup 1, and the other end of the first tube body 3 is fixedly provided with a fixing block 4, and grooves 41 are set on both sides of the fixing block 4. 5 is hinged at one end, and the other end of the ventilation pipe 2 is covered with a second pipe body 6 .

The working principle of the negative pressure pump 7 is: the circular motion of the motor causes the diaphragm inside the pump to reciprocate through the mechanical device, thereby compressing and stretching the air in the pump cavity to form a negative pressure, and generating pressure at the suction port with the external atmospheric pressure. Under the action of the pressure difference, the gas is sucked into the pump chamber and then discharged from the exhaust port.

In this embodiment, the suction cup 1 and the expansion plate 5 on one side of the suction cup 1 are put into the birth canal. After the suction cup 1 is attached to the head of the fetus, a negative pressure is formed in the suction cup 1 by the suction of the negative pressure pump 7. Make the suction cup 1 closely fit with the head of the fetus, and pull the ventilation tube 2 outward to pull the fetus. When preparing to pull the fetus outward, slide the second tube body 6 inward along the ventilation tube 2, so that the top block 61 Slide to the side of the expansion plate 5, and spread the expansion plate 5 according to the angle that it needs to expand, so that the expansion plate 5 expands outward, and the inner walls on both sides of the birth canal are stretched. At the same time, the expansion plate 5 spreads the birth canal in the front, which is convenient to reduce the resistance generated by the traction of the fetus, accelerate the traction work, and save the traction time.

In order to facilitate the smooth entry of the whole device into the birth canal without damaging the inner wall of the birth canal, the first tube body 3 and the second tube body 6 are of the same size, and the first tube body 3 and the second tube body 6 are of the same size, which is convenient for the second tube body When the body 6 moves, it is docked with the first tube body 3, and there will be no resistance from the parturient due to different sizes.

In order to enable the second pipe body 6 to slide tightly with the ventilation pipe 2 and improve the stability of the second pipe body 6, an inner pipe 62 is fixed inside the second pipe body 6, the inner pipe 62 is slidably connected with the ventilation pipe 2, and the inner pipe 62 is The trachea 2 is tightly fitted. In the absence of artificial sliding, the second pipe body 6 slides on the ventilation pipe 2 through the inner pipe 62, which ensures the stability of the expansion plate 5 after being lifted up and prevents the second pipe body 6 from sliding on the ventilation pipe 2 through the inner pipe 62. The body 6 moves freely, so that a permanent lift of the expansion plate 5 is not possible.

In order to facilitate the damage of the top block 61 to the birth canal, the surfaces of the two top blocks 61 are arc-shaped. The arc-shaped structure keeps the surface of the top block 61 smooth. At the same time, the rubber material is preferentially used to ensure the softness of the material. When the top block 61 enters the production The birth canal will not be damaged when sliding in the canal or following the second tube body 6 .

In order for the top block 61 to enter the side of the expansion plate 5 smoothly, arc plates 51 are provided at both ends of the expansion plate 5, and one side of the arc plate 51 is provided with an arc surface. When the expansion plate 5 opens the birth canal, the flexibility of the rubber protects the birth canal. Secondly, the arc plate 51 also facilitates the top block 61 to enter the expansion plate 5 side through thrust.

In order to improve the suction force of the suction cup 1, an extension edge 11 is provided on one side of the suction cup 1, and the extension edge 11 is fixedly connected with the suction cup 1. The extension edge 11 is used to increase the contact distance with the head of the fetus, improve suction, and at the same time protect the head of the fetus to prevent Damaged head.

Further, a plurality of protrusions 12 are arranged on the inner walls of the suction cup 1 and the extension edge 11. The protrusions 12 have a semicircular structure. The protrusions 12 increase the friction with the tire head and increase the stability of traction. The protrusions 12 will not harm the fetus.

When the present invention is used for the vacuum suction obstetrics and gynecology delivery device, the suction cup 1 and the expansion plate 5 on one side of the suction cup 1 are put into the birth canal. Use the suction of the negative pressure pump 7 to form a negative pressure in the suction cup 1, so that the suction cup 1 is closely attached to the fetal head. Pulling the ventilation tube 2 outwards can carry out the work of pulling the fetus. The second tube body 6 slides inward along the ventilation tube 2, and according to the required angle, slides the top block 61 to a suitable position on one side of the expansion plate 5, so that the expansion plate 5 expands outward, wherein the expansion plate 5 passes through the top block The top of 61 expands, and plays the role of spreading the inner walls on both sides of the birth canal. At this time, the tightness of the inner tube 62 and the ventilation tube 2 ensures that the second tube body 6 will not move after the medical staff let go, ensuring the expansion. The plate 5 is in an expanded state. In order to protect the parturient, the expansion plate 5 and the top block 61 are preferably made of rubber material, and the surface has a smooth arc structure. As the ventilation tube 2 is pulled out, the expansion plate 2 is pulled outward. 5. The birth canal is opened in the front, which is convenient to reduce the resistance generated by the traction of the fetus, accelerate the traction work, and save the traction time.

The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and descriptions are only preferred examples of the present invention, and are not intended to limit the present invention, without departing from the spirit and scope of the present invention.
