The transverse screw is arranged in a transverse slide seat, and the length direction of the transverse slide seat is consistent with the length direction of the transverse screw rod. The transverse nut slider forms a sliding guide with the transverse slide seat along the length direction of the transverse screw rod. The transverse nut slider is connected to the slide seat, and one end of the transverse screw is connected to the adjustment handle 331; through the setting of the clamping seat 311 and the fixing screw 312, the function of detachable installation on the edge of the delivery bed is realized, and disassembly and assembly are convenient.

[0047] refer to Figure 3 The suction mechanism 100 includes a cylinder 110 and a suction cup 120. The suction cup 120 is arranged at one end of the cylinder 110, and the other end of the cylinder 110 is connected to a negative pressure pump through a pipe joint 130. The negative pressure pump draws the cylinder 110 into a negative pressure state, and the suction cup 120 fits on the fetal head to achieve the function of sucking the fetus.

[0048] refer to Figure 2 and Figure 3 The adjusting mechanism 200 includes an A adjusting mechanism 210 and a B adjusting mechanism 220. The A adjusting mechanism 210 is connected to the cylinder body 110 and is used to apply traction force to the cylinder body 110 at intervals. The B adjusting mechanism 220 is connected to the A adjusting mechanism 210 and is used to apply stable and continuous traction force to the A adjusting mechanism 210 and the cylinder body 110. Through the setting of the A adjustment mechanism 210, the function of applying traction at intervals is realized, and the traction force is applied at intervals in coordination with the breathing of the parturient and the contraction of the uterus, so as to avoid the problem that the fetus is sucked by the uterus when the uterus contracts violently, and the outside world still maintains a large pulling force outward, which causes the fetus to be unable to be delivered, the fetus is injured, and the parturient is uncomfortable. It effectively ensures that the fetus can be delivered smoothly and safely, and at the same time, it will not cause discomfort and damage to the parturient and the fetus, and meets the current use requirements. When the uterus delivers the fetus outward, the parturient is weak and the delivery force is insufficient. Through the setting of the B adjustment mechanism 220, the delivery force of the uterus is increased, and the fetus is delivered smoothly, and the midwifery effect is good; the A adjustment mechanism 210 is provided with two groups, and the two groups of A adjustment mechanisms 210 are placed on both sides of the cylinder body 110. The two groups of A adjustment mechanisms 210 can more stably adjust the intermittent traction function of the cylinder body 110.

[0049] refer to Figure 5 The A adjustment mechanism 210 includes a slider 212 and a slide groove 211. The length direction of the slide groove 211 is consistent with the length direction of the cylinder body 110. The slider 212 is slidably installed in the slide groove 211. The slider 212 and the cylinder body 110 are fixedly connected. The slider 212 is connected to the A adjustment component. The A adjustment component is used to intermittently apply an elastic force along the length of the slide groove 211 and away from the fetus to the slider 212; through the setting of the slider 212 and the slide groove 211, the A adjustment component intermittently applies traction to the slider 212, the slide groove 211 realizes the role of sliding guidance, and the slider 212 drives the cylinder body 110 to move synchronously, with stable coordination, which meets the current usage requirements.

[0050] refer to Figure 5A regulating component includes a coil 213, the coil 213 is fixed in the slide slot 211, the coil 213 is sleeved on the guide rod 214, the length direction of the guide rod 214 is consistent with the length direction of the slide slot 211, the guide rod 214 is arranged in the slide slot 211, a slider 212 is slidably installed on the guide rod 214, and a permanent magnet 216 is installed on the side of the slider 212 close to the coil 213. Current is intermittently passed through the coil 213, so that the coil 213 intermittently generates a magnetic field. When the magnetic field is generated, it repels the magnetic field of the permanent magnet 216, driving the slider 212 to move outward or making it have a tendency to move outward, so as to exert traction on the slider 212. The intermittent control is convenient, which is convenient for coordinating with the breathing of the parturient or the contraction of the uterus to assist in childbirth. When the uterus contracts, no current is passed through the coil 213, the slider 212 does not move, and no traction is applied to the fetus. When the uterus is contracted, traction is applied to the fetus to achieve the function of assisting childbirth. According to the duration of contraction, the duration of the coil 213 being energized is adjusted, and the adjustment and control are convenient and reliable, meeting the current use requirements. Figure 6 The coil 213 is installed in the shell, and the shell is fixedly installed on the inner wall of the slide groove 211.

[0051] refer to Figure 5 A spring 215 is also installed between the coil 213 and the slider 212. The spring 215 is sleeved on the guide rod 214. One end of the spring 215 abuts against the coil 213, and the other end abuts against the slider 212. The setting of the spring 215 realizes a buffering function. Since the permanent magnet 216 and the coil 213 repel each other at the moment when the coil 213 is energized, the slider 212 moves faster, which will cause an impact force. The spring 215 can effectively buffer and avoid impact on the fetus. At the same time, after the power is turned off, the spring 215 can also realize a reset function, so that the traction force on it disappears, which is convenient for the parturient to give birth.

[0052] refer to Figure 4 The B adjustment mechanism 220 includes a nut slider, a screw and a slide 222. The nut slider is assembled on the screw, which is arranged in the slide 222. The length direction of the screw rod is consistent with the length direction of the slide 222. The nut slider forms a sliding guide with the slide 222 along the length direction of the screw rod. The nut slider is fixedly connected to the slide. The end of the screw away from the suction cup 120 extends out of the slide and is connected to the driving component. If the parturient is not strong enough to deliver, the screw drives the nut slider to move, and the nut slider drives the slide to move, and then the cylinder pulls the fetus to deliver, realizing the function of assisting delivery.

[0053] refer to Figure 4 The driving assembly includes a rotating handle 221, the rotating handle 221 is connected to a rotating nut, the rotating nut is assembled on the screw, and the rotating nut is rotatably mounted on the end of the slide. By setting the rotating handle 221, the function of manual traction can be realized. According to the different delivery forces of different parturients, the rotating handle 221 can be adjusted to realize the function of adjustable traction force, which has wide applicability and meets the current use requirements.

[0054] refer to Figure 7 The suction cup 120 is a disposable plastic component. The suction cup 120 is provided with a threaded interface 121. The cylinder body 110 is provided with a threaded joint 111. The threaded interface 121 is assembled on the threaded joint 111. Through the arrangement of the threaded mechanism 121 and the threaded joint 111, the suction cup 120 is detachably installed, and the replacement is convenient and simple, avoiding the problem of the traditional integrated structure of the suction device, which needs to be cleaned and disinfected once, or is scrapped after one use, effectively reducing the use cost and meeting the current use requirements.

[0055] When using the invention, firstly, the present invention is clamped on the edge of the delivery bed, and the height of the suction mechanism 100 is adjusted by the electric cylinder. By rotating the adjustment handle 331, the lateral position of the suction mechanism 100 is adjusted to the position corresponding to the birth opening of the parturient. Then, the suction cup 120 on the suction mechanism 100 and the head or back of the fetus that is difficult to deliver are placed on the cylinder body 110 to draw negative pressure to suck the fetus. The rotating handle 221 is adjusted to apply a small traction force to the cylinder body 110. Then, according to the contraction and expansion of the parturient's uterus, whether the coil 213 is energized is adjusted. When the parturient's uterus and birth canal expand, the coil 213 is energized to generate a magnetic field. The magnetic field and the permanent magnet 216 repel each other and apply a repulsive force to the slider 212. The slider 212 transmits the force to the cylinder body 110 to apply traction to the fetus and realize the traction and midwifery function. When the parturient's uterus and birth canal contract, the coil 213 is powered off and slightly reset under the action of the spring 215 to avoid pulling the fetus and causing discomfort or damage to the parturient's birth canal and uterus.

[0056] The invention can be detachably installed on the edge of the delivery bed. When it is needed, it is easy to assemble. The position of the suction mechanism can be adjusted according to the different parturients to make it correspond to the parturient's birth opening. The adjustment is simple and the use is convenient.
