[0002] Infant delivery refers specifically to the period and process during which the fetus separates from the mother's body and becomes an independent individual. The entire delivery process is divided into three stages, also known as the three stages of labor. The first stage of labor is the stage of cervical dilation. The second stage of labor is the stage of fetal delivery. The third stage of labor is the stage of placental delivery.

[0003] When teaching infant delivery, the personal privacy of the mother should be taken into consideration during the real-time teaching process, and it is not appropriate to teach publicly. Some video materials are prone to insufficient disclosure during teaching, thus affecting the actual effect of infant delivery teaching.

The following examples are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0047] Embodiment 1:

The cervical os simulation mold 3 and the baby head simulation ball 4 can cooperate to simulate the baby delivery process;

[0050] The propulsion control assembly 5 includes a threaded cylinder 501, a limiting track 502, and a rotating rocker 503. One end of the rotating rocker 503 is fixed to the central axis of the threaded cylinder 501. The threaded cylinder 501 is threadedly connected to the inner side of the limiting track 502. The end of the threaded cylinder 501 away from the rotating rocker 503 is fixed with a transmission ball 504 through a bearing. One end of the baby head simulation ball 4 is embedded in the transmission ball 504 and rotates freely. The limiting track 502 is fixed to the inner side of the main frame 1.

[0051] When the rocker 503 is rotated, the threaded cylinder 501 can be driven to rotate. At this time, the threaded cylinder 501 is correspondingly advanced or withdrawn along the direction of the limiting track 502, and then the transmission ball 504 is pushed to move correspondingly, thereby driving the baby head simulation ball 4 to move correspondingly;

[0052] The head adjustment control assembly 6 includes a connector 601, a steering mechanism 602, a traction rope 603 and an electric telescopic rod 604. The connector 601 is movably connected to the side of the baby head simulation ball 4. One end of the traction rope 603 is fixed to the connector 601. The other end of the traction rope 603 passes through the traction rope 603 and is fixed to the output end of the electric telescopic rod 604. The electric telescopic rod 604 is fixed to one end of the inner side of the main frame 1.

[0053] The electric telescopic rod 604 can control the extension or release of the traction rope 603, and the traction rope 603 changes direction through the steering mechanism 602, and then pulls the baby head simulation ball 4 to rotate through the connecting head 601;

[0054] The abdominal cavity simulation component 7 includes a hard shell 701, a thin leather cover 702 is fixedly provided on the top of the hard shell 701, a metal tray 703 is slidably connected to the inside of the hard shell 701, a ceramic holder 704 is fixedly provided at the bottom of the metal tray 703, paraffin is placed just above the metal tray 703, a heating rod 705 is clamped in the middle of the ceramic holder 704, the bottom end of the heating rod 705 is connected to a battery 7011 and a circuit breaker controller 7012 located at the bottom of the hard shell 701 through a soft wire, a screw hole 7041 is provided on one side of the bottom end of the ceramic holder 704, and a heating rod 705 is clamped in the middle of the ceramic holder 704 through a soft wire. 041 is threadedly connected with a first straight rod 7042, and a stabilizing frame 7043 is sleeved on the side of the first straight rod 7042 through a bearing sleeve, a lifting drive motor 7013 is fixedly provided at the inner bottom of the hard shell 701 and close to one side of the first straight rod 7042, and the output end of the lifting drive motor 7013 is transmission-connected to the first straight rod 7042 through a coupling, a through hole 7044 is provided at the other side of the bottom end of the ceramic bracket 704, and a second straight rod 7045 is fixedly provided at the inner bottom of the hard shell 701 and close to one side of the through hole 7044, and is slidably connected to cooperate with the through hole 7044;

[0055] In the abdominal simulation component 7, the lifting drive motor 7013 is working to control the rotation of the first straight rod 7042. At this time, since the straight hole 7044 and the second straight rod 7045 cooperate to slide, the screw hole 7041 and the first straight rod 7042 cooperate to be threadedly connected, the ceramic bracket 704 can be controlled to lift and lower, and then the metal tray 703 and paraffin can be controlled to lift and lower. When simulating the change of hardness and softness of the abdomen, the battery 7011 provides power, and then the circuit breaker controller 7012 controls the opening and closing of the circuit, so that the heating rod 705 is in a heating or cooling state, and the temperature is transmitted to the metal tray 703, and the melting or solidification of the paraffin is further controlled. When the paraffin melts, the softness is generated by touching the thin leather cover 702. When the paraffin solidifies again, the hardness is generated by touching the thin leather cover 702, thereby realizing the change of hardness and softness of the abdomen. At the same time, the position of the paraffin is controlled to simulate the bulge or flatness of the abdomen.

[0059] The cervical os simulation mold 3 is a trumpet-shaped hollow structure made of latex material as a whole, and when the baby head simulation ball 4 contacts the cervical os simulation mold 3, the trumpet simulation mouth 302 will open, at this time the opening process of the cervical os can be simulated, and the concentrated connection point 301 can ensure that one end of the cervical os simulation mold 3 remains fixed.

[0061] The T-joint 3022 can only move in translation in the T-shaped inner groove 101. When the baby head simulation ball 4 contacts and squeezes the cervical os simulation mold 3, the trumpet simulation opening 302 on the cervical os simulation mold 3 is evenly expanded, so as to better simulate the opening of the cervical os.

[0065] The extension strip 3021 is also a hollow structure. The water tank 3025 is used to store water and water is injected into the speaker simulation port 302 through the extension strip 3021 to change the hardness of the speaker simulation port 302 .

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment, based on the above method, further, a piston 3026 is slidably connected to the inner side of the water tank 3025, a water supply pipe 3027 is fixedly provided at the top of the water tank 3025, and a closing valve 3028 is fixedly sleeved on the water supply pipe 3027;

[0067] The closing valve 3028 controls the flow or closing of the water filling pipe 3027, and then water is added to the water tank 3025 through the water filling pipe 3027. Then, the piston 3026 can be operated to push the water in the water tank 3025 out, or to bring the water in the water filling pipe 3024 back to the water tank 3025.

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the rotating rocker 503 includes an L-shaped rod 5031 and a crank 5032, and the crank 5032 is fixed to a side of the L-shaped rod 5031 away from the threaded cylinder 501;

[0069] When the crank 5032 is rotated, the threaded cylinder 501 is driven to rotate through the L-shaped rod 5031, and the crank 5032 performs a circular motion, thereby improving the convenience of operating the crank 5032.

[0070] like Figure 1 , Figure 2 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a back plate 103 fixed to the operating microcomputer 2 is provided on one side of the main frame 1, and a circular through groove 1031 is opened on the back plate 103, and the inner diameter of the circular through groove 1031 is larger than the circumferential radius of the crank 5032 when it rotates;

[0071] One end of the L-shaped rod 5031 can pass through the circular through slot 1031 on the back plate 103, so as to facilitate bringing the crank 5032 out to the outside of the main frame 1, thereby improving the convenience of rotating the crank 5032 for use.

[0073] The arc block 6011 slides in the arc groove 401. When the traction rope 603 is pulled, the traction rope 603 pulls the arc block 6011 to slide in the arc groove 401. When the arc block 6011 contacts one end of the arc groove 401, it can drive the baby head simulation ball 4 to rotate.

[0075] The fixed pulley 6022 can change the direction of the force of the traction rope 603, thereby facilitating the operation of the four traction ropes 603. Then, the universal joint can be used to change the angle of the fixed pulley 6022 as a whole, thereby reducing the friction between the traction rope 603 and the edge of the fixed pulley 6022, or the traction rope 603 is stuck in the fixed pulley 6022, thereby improving the operational convenience of the traction rope 603.

[0076] Embodiment 3:

[0077] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0078] Specifically, when the obstetric delivery observation simulation teaching aid is used: the cervical os simulation mold 3 and the baby head simulation ball 4 can cooperate to simulate the baby delivery process. During the simulated delivery, the operating microcomputer 2 can be used to set the program and control the operation of the propulsion control component 5 and the head adjustment control component 6, thereby better simulating the situation of baby delivery;

[0079] First, the hardness of the cervical os simulation mold 3 is adjusted, specifically: the closing valve 3028 controls the flow of the water supply pipe 3027, and then water is added to the water tank 3025 through the water supply pipe 3027, and then the closing valve 3028 is closed, and then the piston 3026 is operated to push out the water in the water tank 3025, and the water passes through the water injection pipe 3024 and the hollow extension strip 3021 and is injected into the interior of the cervical os simulation mold 3. By controlling the amount of water, the hardness of the cervical os simulation mold 3 can be accurately controlled;

[0080] At the same time, the lifting drive motor 7013 works to control the rotation of the first straight rod 7042. At this time, since the through hole 7044 and the second straight rod 7045 slide together, the screw hole 7041 and the first straight rod 7042 are threadedly connected together, the ceramic bracket 704 can be controlled to lift and lower, and then the metal tray 703 and the paraffin can be controlled to lift and lower. When simulating the change of hardness and softness of the abdomen, the battery 7011 provides power, and then the circuit breaker controller 7012 controls the opening and closing of the circuit, so that the heating rod 705 is in a state of heating or cooling, and the temperature is transmitted to the metal tray 703, and the melting or solidification of the paraffin is further controlled. When the paraffin melts, the softness is felt by touching the thin leather cover 702. When the paraffin solidifies again, the hardness is felt by touching the thin leather cover 702, so that the hardness and softness of the abdomen can be changed. At the same time, the position of the paraffin can be controlled to simulate the degree of bulge of the abdomen.

[0081] Then, the expansion degree of the cervical os simulation mold 3 is controlled by the propulsion control component 5, specifically: the crank 5032 is turned to drive the threaded cylinder 501 to rotate through the L-shaped rod 5031, at this time, the crank 5032 performs a circular motion, the threaded cylinder 501 is correspondingly pushed along the direction of the limit track 502, and then the transmission ball 504 is pushed to move accordingly, thereby driving the baby head simulation ball 4 to move accordingly. When the baby head simulation ball 4 contacts and squeezes the cervical os simulation mold 3, the horn simulation mouth 302 will move. The cervical opening is opened, and the opening process of the cervical opening can be simulated at this time. The centralized connection point 301 can ensure that one end of the cervical opening simulation mold 3 remains fixed; at the same time, the T-joint 3022 moves in translation in the T-shaped inner slide groove 101, and the ultrasonic ranging probe 102 emits ultrasonic waves, and the sound waves are reflected by the sound wave reflection block 3023. According to the time from the emission to the reception of the sound waves, the moving distance of the extension strip 3021 is determined, and the baby delivery process can be effectively simulated through the opening position of the cervical opening simulation mold 3 and the position of the baby head simulation ball 4;

[0082] During the simulated delivery process, the head adjustment control component 6 can be used to control the angle of the baby's head simulation ball 4, specifically: the electric telescopic rod 604 can control the stretching or release of the traction rope 603. When the traction rope 603 is pulled, the traction rope 603 pulls the arc block 6011 to slide in the arc chute 401. When the arc block 6011 contacts one end of the arc chute 401, it can drive the baby's head simulation ball 4 to rotate. The four traction ropes 603 can control the baby's head simulation ball 4 to rotate in four different directions, thereby accurately simulating the head direction of the baby during delivery;
