[0002] In medical education and training, dynamic demonstrations of embryo position and cervical patency through teaching models are essential for understanding the spontaneous abortion process during undergraduate theoretical lectures, internships, and standardized resident training. While traditional uterine models can provide some teaching assistance, their functionality is often limited, particularly due to the fixed embryo position and closed cervical os. This significantly limits the practice and understanding of miscarriage type determination during undergraduate theoretical lectures, internships, and standardized resident training.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a natural abortion teaching model, such as Figure 1-Figure 5 As shown, it includes a model body 1, the top interior of the model body 1 is set as the uterine cavity, the interior of the model body 1 is provided with an embryo 2, and the position of the embryo 2 in the model body 1 can be adjusted by the embryo position adjustment structure. The inner wall of the top of the model body 1 is provided with a uterine cavity 3, and the middle of the interior of the model body 1 is provided with a cervical os 4. The cervical os telescopic structure is provided at the cervical os 4. The cervical os telescopic structure includes two symmetrically arranged air bags 5, and the two air bags 5 are inflated and deflated by an air pump 11. The embryo position adjustment structure includes a motor 12 and a pull rope 121. One end of the pull rope 121 is wrapped around the output shaft of the motor 12, and the other end of the pull rope 121 slides through the side wall of the model body 1 and extends into the interior of the uterine cavity and is connected to the embryo 2. Among them, the internal space inside the model body 1 and located above the cervical os 4 is the uterine cavity; in the initial position, the embryo 2 is attached to the uterine cavity 3.

[0024] The embryo 5 within the main body 1 of the model is adjusted in position by an embryo position adjustment mechanism, simulating different embryo positions within the uterine cavity. This intuitively demonstrates the changing position of the embryo in different types of miscarriage, providing a clear and dynamic visual experience for undergraduate trainee theory lectures, internships, and standardized resident training and teaching rounds. The telescopic cervical os 4, located at the cervix, opens and closes via the inflation and deflation of two airbags 5. This design allows the model to simulate the opening and closing of the cervix in different types of miscarriage, enhancing its realism and teaching effectiveness. Combining the changing position of the embryo and the opening and closing of the cervix, the model can comprehensively and accurately simulate different types of miscarriage, providing a more realistic teaching tool for undergraduate trainee theory lectures, internships, and standardized resident training and teaching rounds. This not only helps students better understand and grasp the types of miscarriage and related knowledge, but also enhances their learning interest and practical skills.

[0025] In this embodiment, the back of the model body 1 is supported by a bracket 7 , a base 6 is installed at the bottom of the bracket 7 , and the bottom end of the bracket 7 is hinged to the base 6 .

[0026] Specifically, a cylinder 8 is mounted on the base 6. The top output end of the cylinder 8 is connected to the bracket 7 via a connecting rod 9. The top end of the connecting rod 9 is hinged to the bracket 7, and the bottom end of the connecting rod 9 is hinged to the top piston rod of the cylinder 8. The extension and retraction of the piston rod of the cylinder 8 drives the bracket 7 to flip, thereby adjusting the tilt angle of the model body 1.

[0027] Furthermore, the motor 12 is installed on the top back of the bracket 7, the air pump 11 is installed on the top of the base 6, and the output end of the air pump 11 is connected to the two air bags 5 through a pipeline to achieve size adjustment of the air bags 5.

[0028] Furthermore, a controller 13 is mounted on the top of the base 6. The controller 13 is equipped with a forward button and a reverse button. The controller 13 is electrically connected to the motor 12 via a wire. Initially, a pull cord 121 is wrapped around the output end of the motor 12. The controller 13 controls the forward and reverse rotation of the motor 12, which in turn causes the output end of the motor 12 to retract and expand the pull cord 121, thereby adjusting the position of the embryo 2.

[0029] Furthermore, a transparent cover 10 is installed on the outer side of the front of the model body 1. The top of the transparent cover 10 is hinged to the upper part of the model body 1, which facilitates the opening and closing of the transparent cover 10. The transparent cover 10 can also protect the interior of the model body 1 from being damaged by collision.

[0030] Furthermore, the width of the cervical os 4 is smaller than the inner wall width of the model body 1, and the airbag 5 is located on the inner side of the cervical os 4. The cervical os 4 is made of sponge material to ensure that the cervical os 4 has a certain elasticity. When the airbag 5 expands or contracts, the size of the cervical os can be simulated and adjusted.

[0031] When using the natural abortion teaching model of the present invention, the model body 1 is first supported by a bracket 7 and mounted on a base 6. The bottom end of the bracket 7 is hinged to the base 6, so that the model body 1 can be tilted. The cylinder 8 on the base 6 is connected to the bracket 7 through a connecting rod 9. When the cylinder 8 is working, it will drive the bracket 7 to flip, thereby adjusting the tilt angle of the model body 1 to meet different teaching and demonstration needs.

[0032] Embryo 2 is positioned within the model body 1, and its position is adjusted by an embryo position adjustment mechanism. This mechanism includes a motor 12 and a pull cord 121. One end of the pull cord 121 is wrapped around the output shaft of motor 12, and the other end passes through the model body 1 and connects to the embryo 2. When motor 12 is operating, it retracts and extends the pull cord 121, thereby adjusting the position of embryo 2 within the model body 1, simulating different embryo positions within the uterine cavity.

[0033] Furthermore, a cervical os 4 is located in the center of the model body 1, and a cervical os expansion and contraction structure is provided at the cervical os 4. This expansion and contraction structure comprises two symmetrically arranged airbags 5, which are inflated and deflated by an air pump 11. When the air pump 11 is activated, it inflates and deflates the airbags 5, thereby expanding and contracting the cervical os 4, simulating the opening and closing of the cervical os in different abortion scenarios.

[0034] During the demonstration, the cylinder 8 is first used to adjust the tilt angle of the model body 1 to position it in an appropriate teaching display position. Then, the controller 13 controls the forward and reverse rotation of the motor 12, driving the pull rope 121 to retract and extend, thereby changing the position of the embryo 2 within the model body 1. Simultaneously, the air pump 11 inflates and deflates the two air bags 5 to open and close the cervix 4. By combining the different positions of the embryo 2 and the opening and closing of the cervix 4, different types of miscarriage can be fully and accurately simulated, providing a clear and dynamic visual experience for undergraduate theoretical lectures, internships, and standardized training and teaching rounds for resident physicians.

[0035] In addition, a transparent cover 10 is installed on the front outer side of the model body 1 to facilitate observation of the changes in the embryo 2 and the cervical os 4. The cervical os 4 is made of sponge material with a certain degree of elasticity. When the airbag 5 expands or contracts, the size of the cervical os can be simulated and adjusted.

[0036] It is worth noting that the types of miscarriage corresponding to the different positions of the embryo 2 and the opening and closing state of the cervix 4 are as follows:

[0037] (1) When the embryo 2 is slightly separated from the uterine cavity 3 (e.g. Figure 1 As shown), it is a threatened abortion, at which time the cervix 4 is in a completely closed state;

[0038] (2) Embryo 2 slips into the uterine cavity or the fetal membrane ruptures (e.g. Figure 2 Sometimes the embryo 2 is blocked at the cervical os 4, which is an inevitable miscarriage. At this time, the cervical os 4 is in a slightly open state.

[0039] (3) Embryo 2 is partially expelled from the uterine cavity, partially embedded in the cervix, or partially remains in the uterine cavity (e.g. Figure 3 As shown), part of the embryo 2 falls outside the cervical os 4, which is an incomplete abortion. At this time, the cervical os 4 is in a fully open state;

[0040] (4) All embryos 2 are expelled from the uterine cavity (e.g. Figure 4 As shown), it is a complete miscarriage, at which time the cervix 4 is in a completely closed state;

[0041] Finally, it should be noted that the motor 12, controller 13, etc. in this embodiment, the electronic components in the above parts are all universal standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
