Description

Technical Field

[0001] The present invention relates to the technical field of obstetric auxiliary instruments, and specifically relates to an obstetric suction cup midwifery device. Background Art

[0002] Everyone's birth is the process of being born from the mother's womb, and this process is extremely arduous. Every year, many mothers and infants lose their lives during difficult childbirth, and the medical community attaches great importance to this. Various midwifery devices have gradually come into people's view. Taking the suction cup midwifery device as an example, it pulls the infant out of the birth canal through the suction cup, which is very common in current clinical operations.

[0003] The prior patent document with the application number 201711224920.1 provides an obstetric suction cup midwifery device, including a suction cup midwifery mechanism, support foot pads, a base, a dust cover, and a controller. The bottom surface of the base is fixedly connected to the top surface of the support foot pads at the four corner positions. There are 4 support foot pads, and they are identical in shape and size. The four corners of the base are chamfered. This device does not require manual holding of the delivery suction cup for midwifery, which can avoid the situation of improper force and unstable force when holding the suction cup, resulting in injury to the infant's limbs. The rotation speed of the silent motor is stable, so the force on the piston rod is stable, ensuring the limb safety of the infant during childbirth midwifery. Although this patent has many beneficial effects, there are still the following deficiencies: Since the sleeve is fixedly connected to the support leg, and the support leg is fixedly connected to the base, the height of the sleeve is fixedly set and cannot be adjusted. Furthermore, the sleeve cannot meet the different height requirements needed by different patients during use, and the sleeve cannot be retracted after using the entire midwifery device, which has great limitations.

[0004] Therefore, to solve the above problems, the present invention proposes an obstetric suction cup midwifery device. Summary of the Invention

The two adjustment gears 43 in the adjustment mechanism 4 are both located inside the installation groove 3. The support wheels 45 in the adjustment mechanism 4 are respectively slidably connected inside the support grooves 7. The two transmission support feet 44 in the adjustment mechanism 4 are both located inside the retraction groove 6. The support wheels 45 facilitate driving the lifting plate 2 to rise by sliding connection with the support grooves 7.

[0023] Specifically, the transmission mechanism 5 includes a first motor 51, a bidirectional lead screw 52, and a T-shaped guide rod 53. On the bidirectional lead screw 52, symmetrically arranged transmission racks 54 are threadedly connected. On one side of each of the transmission racks 54, a T-shaped guide groove 55 is opened corresponding to the position of the T-shaped guide rod 53.

[0024] Specifically, the bidirectional screw rod 52 in the transmission mechanism 5 is rotatably connected to one side inside the mounting groove 3, the first motor 51 in the transmission mechanism 5 is fixedly mounted on the back side of the base 1 at a position corresponding to the bidirectional screw rod 52, the T-shaped guide rod 53 in the transmission mechanism 5 is fixedly connected to the inner side wall of the mounting groove 3, the two transmission racks 54 in the transmission mechanism 5 are located inside the mounting groove 3 and are respectively meshed with the two adjustment gears 43 in the adjustment mechanism 4, the bidirectional screw rod 52 in the transmission mechanism 5 is fixedly connected to the output end of the first motor 51, the T-shaped guide rod 53 in the transmission mechanism 5 is slidably connected to the T-shaped guide groove 55 on the two transmission racks 54, the two transmission racks 54 are convenient for driving the two adjustment gears 43 to rotate, and the first motor 51 is convenient for driving the bidirectional screw rod 52 to rotate.

[0025] Specifically, the delivery-aiding mechanism 8 includes a sleeve 81, a pressure plate 82 is slidably connected inside the sleeve 81, a pumping rod 83 is slidably connected inside the sleeve 81, a suction cup 84 is fixedly connected to one side of the sleeve 81, and a transmission block 85 is fixedly connected to one side of the pumping rod 83.

[0026] Specifically, the sleeve 81 in the midwifery mechanism 8 is fixedly connected to the top of the lifting plate 2, one side of the pulling rod 83 in the midwifery mechanism 8 slides through the side wall of the sleeve 81 and is fixedly connected to the transmission block 85, one side of the pressure plate 82 in the midwifery mechanism 8 is fixedly connected to the pulling rod 83, the suction cup 84 in the midwifery mechanism 8 is conical, and the transmission block 85 in the midwifery mechanism 8 is located at the bottom end of the connecting rod 18, and the groove on the transmission block 85 in the midwifery mechanism 8 is the same shape as the bottom end of one side of the connecting rod 18, so that the transmission block 85 is convenient to be plugged into the connecting rod 18.

[0027] Specifically, the folding groove 6 is located at the middle position of the symmetrically arranged supporting grooves 7, the folding groove 6 is in a communicating state with the two supporting grooves 7, the rotating rod 10 is located at the middle position of the symmetrically arranged transmission rod 11, the driving gear 12 is meshed and connected with two driven gears 13, one of the half gears 14 is meshed and connected with the driven rack 16, the top end of the rotating rod 10 is fixedly connected to the output end of the second motor 19, the driving gear 12 is convenient for driving the two driven gears 13 to rotate, and the half gear 14 is convenient for driving the driven rack 16 to move laterally.

[0028] During use, first, the output end of the first motor 51 drives the bidirectional lead screw 52 to rotate. The rotation of the bidirectional lead screw 52 will drive the two transmission racks 54 to move towards the middle direction simultaneously. When the transmission racks 54 move towards the middle direction, the sliding connection between the T-shaped guide rod 53 and the T-shaped guide groove 55 will guide the movement of the transmission racks 54, making the movement of the transmission racks 54 smoother. The movement of the two transmission racks 54 will also drive the two adjustment gears 43 to rotate simultaneously. When the adjustment gears 43 rotate, they will drive the transmission round rods 42 to rotate respectively. The simultaneous rotation of the two transmission round rods 42 will drive the transmission support feet 44 to rotate respectively. The two transmission support feet 44 will rotate around the transmission round rods 42 as the center. The rotation of the transmission support feet 44 will drive the support wheels 45 to rotate upwards. The support wheels 45 on the two transmission support feet 44 will rotate and slide inside the support groove 7, as Figure 2 , causing the lifting plate 2 to be lifted. The lifting of the lifting plate 2 will drive the sleeve 81 to rise together. At this time, the height adjustment of the lifting plate 2 is completed, and the transmission block 85 on the extraction rod 83 has also been inserted into the linkage rod 18. At this time, the extraction rod 83 can be moved to extract air, creating negative pressure inside the sleeve 81. The elevation of the extraction rod 83 and the sleeve 81 causes the extraction rod 83 to be misaligned with the second motor 19, so that the extraction rod 83 will not touch the second motor 19 when it is driven to move. Then, the second motor 19 drives the rotating rod 10 to rotate. The rotation of the rotating rod 10 will drive the driving gear 12 to rotate. The rotation of the driving gear 12 will drive the two driven gears 13 to rotate. The rotation of the two driven gears 13 will drive the transmission rods 11 to rotate respectively. The two transmission rods 11 will drive the half gears 14 to rotate respectively. The rotation of one of the half gears 14 will drive the driven rack 16 to move outwards of the moving groove 9. The movement of the driven rack 16 is guided by the limiting rod 15. The movement of the driven rack 16 will drive the L-shaped rod 17 and the linkage rod 18 to move together. The movement of the linkage rod 18 will drive the extraction rod 83 to move through the transmission block 85. The extraction rod 83 drives the pressure plate 82 to move inside the sleeve 81, creating negative pressure inside the sleeve 81, so that the suction cup 84 can suck the baby's head. Initially, when the half gear 14 connected to the driven rack 16 drives the driven rack 16 to move out to the maximum extent, this half gear 14 will rotate to an angle where it is no longer connected to the driven rack 16. At this time, the other half gear 14 will rotate to an angle where it is connected to the driven rack 16. The continued rotation of the other half gear 14 at this time will drive the driven rack 16 to retract into the moving groove 9, so that the extraction rod 83 and the pressure plate 82 are both reset. And this process can be achieved as long as the second motor 19 rotates normally in one direction.
