Abstract
Description
Technical Field
[0001] The utility model relates to a multifunctional pregnant belly model, belonging to the field of teaching aids. Background Art
[0002] In the past, the mastery of abdominal examination skills during pregnancy required a long time of practice and exploration on parturients. However, with the enhancement of parturients' self - protection awareness, clinical teaching teachers are afraid to let students practice freely, greatly reducing the opportunities for students' clinical operations. Therefore, we can no longer rely entirely on practicing on parturients to master skills.
[0003] Nowadays, the application of simulation models in teaching helps students master skills. However, the current teaching models are nearly half - body models (below the neck and above the thighs). Such half - body models are quite different from the actual situation, unable to give students a good overall feeling, not facilitating the understanding and mastery of the entire process of palpation examination, and also unable to experience some details that should be noted during the examination process. The simulation is poor and the functions are single, failing to achieve an ideal teaching effect. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide a multifunctional pregnant belly model.
[0005] A multifunctional pregnant belly model includes a base, a skin layer covering the outside of the base, and a function simulation module. Fixed straps for fixing on the waist and abdomen of a person are arranged on both sides of the base. A placement groove is arranged inside the base, and a movable simulated fetus is arranged in the placement groove for fetal heart simulation, four - step palpation simulation, and measurement of fundal height and abdominal circumference. Compared with the existing half - body models, by designing the model as a wearable structure, the utility model can be directly fixed on the waist and abdomen of students or teaching mannequins, being close to the posture and examination environment of real pregnant women, which helps students obtain a more real and intuitive clinical examination experience, thus better understanding and mastering the abdominal examination skills during pregnancy. By arranging a placement groove inside the base and equipping it with a movable simulated fetus, training on core skills such as fetal heart positioning and fetal position judgment can be carried out, especially suitable for the systematic teaching of the four - step palpation method, enhancing students' practical ability and clinical thinking. The model adopts a wearable design, facilitating the development in various teaching scenarios, such as skill training rooms, group teaching, and even remote teaching demonstrations, improving the convenience and coverage of model use. Key positions of the four - step palpation (fundus, fetal back, fetal head, fetal limbs) are marked on the abdominal surface, guiding users to operate through color or concave - convex design.
[0006] Preferably, the fixing belts on both sides of the base are fixedly connected by Velcro or quick-release buckles. The Velcro or quick-release buckle fixing method allows the model to be quickly and firmly fixed to the user's waist and abdomen, making the wearing and removal process more convenient, improving the operating efficiency during the teaching process; at the same time, it is suitable for students of different body shapes to wear, enhancing the versatility and comfort of the model, and helping to simulate a more realistic pregnant woman's abdominal state, thereby improving the simulation and experience of teaching.
[0007] Preferably, the functional simulation module is arranged inside the simulated fetus, and the functional simulation module includes an ultrasonic sensor or a pressure sensor for simulating fetal heartbeat and fetal movement, and the ultrasonic sensor or the pressure sensor is located at the heart position of the simulated fetus. By setting the functional simulation module inside the simulated fetus and arranging the sensor at the heart position, the heartbeat and fetal movement characteristics of the fetus can be reproduced more realistically, so that students can perceive close to real physiological reactions during palpation, and improve their mastery of skills such as fetal heart position judgment and fetal movement monitoring; at the same time, advanced sensing devices such as ultrasonic sensors or pressure sensors are used to improve the sensitivity and accuracy of the model's response, enhance the interactivity and technical content of the teaching process, and enable students to obtain a more comprehensive and realistic operation training experience without clinical risks.
[0008] Furthermore, the functional simulation module is also provided with a small audio player located inside the simulated fetus, and the small audio player is pre-recorded with real fetal heart sounds and has a volume adjustment function. By pre-recording real fetal heart sounds with a built-in small audio player, students can hear fetal heartbeats close to the real situation during simulated operations, which helps to improve the ability to recognize and judge fetal heart sounds. The volume adjustment function makes the audio output more flexible. Whether in a noisy environment or in a teaching scenario of fine listening, the volume can be adjusted as needed to ensure the best presentation of teaching effects. Integrating the audio player inside the simulated fetus does not interfere with the overall structure, and can increase feedback information during the operation without sacrificing the realism of the model, thereby enhancing students' overall palpation experience and promoting the mastery of clinical skills.
[0009] Preferably, fixing blocks for simulating a tight fit of the fetus are provided on both sides of the placement groove. A rechargeable power source for supplying power to the functional simulation module is provided inside the fixing blocks, and an interface for charging the rechargeable power source is provided on the fixing blocks. The setting of the fixing blocks can make the simulated fetus be more firmly placed in the placement groove, avoiding loosening or displacement during the operation, so as to ensure that stable and consistent feedback can be obtained for each palpation and various simulation operations. A rechargeable power source is provided inside the fixing blocks to provide continuous and stable power support for the functional simulation module. This design makes the operation of various functions (such as ultrasonic / pressure sensing, audio playback, etc.) more reliable, and at the same time eliminates the cumbersome external power supply. A charging interface is provided on the fixing blocks, which can achieve fast and convenient power supply to ensure sufficient power during teaching and training.
[0010] Preferably, the skin layer simulates the shape of a pregnant woman's abdomen. A connecting sleeve is provided inside the skin layer, and the skin layer is tightly and fittingly connected to the base through the connecting sleeve. Through the tight and fitting connection of the connecting sleeve and the base, the stable connection between the skin layer and the base is realized. This structure not only ensures the tight fit between all parts, but also facilitates the assembly and disassembly of the model and subsequent cleaning and maintenance. Through the integration of the skin layer, the connecting sleeve and the base, the model can more comprehensively reproduce the appearance and structural layout of a pregnant woman's abdomen, providing a more comprehensive and real practice environment for students and promoting the accurate mastery of clinical skills.
[0011] Furthermore, the skin layer is made of elastic medical silicone or thermoplastic polyurethane material, and a lightweight plastic frame or high-density foam is filled inside for maintaining the shape of the model. Using elastic medical silicone or thermoplastic polyurethane material can more realistically reproduce the touch and softness of the skin of a pregnant woman's abdomen, providing a more consistent hand feeling with clinical conditions for students during operations such as palpation. Setting a lightweight plastic frame or filling with high-density foam inside can effectively maintain the overall shape of the model, avoiding deformation caused by long-term use or repeated touching, so as to ensure that a consistent structure and feedback effect can be provided each time it is used.
[0012] Preferably, a first magnet is provided on the simulated fetus, and a second magnet magnetically connected to the simulated fetus is provided at the bottom of the placement groove. By using magnetic connection, the rapid disassembly, installation and replacement of the simulated fetus can be easily realized during the teaching process, reducing the complexity of maintenance and adjustment, and improving the applicability and flexibility of the model in various teaching scenarios.
[0013] Preferably, buttons for opening, closing and controlling different functional simulation modules are provided at the bottom of the base. By centrally arranging the control buttons at the bottom of the base, centralized management and control of all functional simulation modules (such as fetal heart simulation, fetal movement detection, etc.) can be realized, facilitating the operator to quickly start and stop various functions and improving the convenience of instrument operation during the teaching process.
[0014] The beneficial effects of the present utility model are as follows: Compared with the existing half-body models, by designing the model as a wearable structure, the present utility model can be directly fixed on the waist and abdomen of students or teaching models, being close to the posture and examination environment of real pregnant women, which helps students obtain a more real and intuitive clinical examination experience, thus better understanding and mastering the skills of abdominal examination during pregnancy. By providing a placement groove in the base and equipping with a movable simulated fetus, training on core skills such as fetal heart positioning and fetal position judgment can be carried out, especially suitable for the systematic teaching of the four maneuvers of Leopold, enhancing students' practical ability and clinical thinking. The model adopts a wearable design, facilitating implementation in various teaching scenarios, such as skill training rooms, group teaching, and even remote teaching demonstrations, improving the convenience and coverage of model use. The key positions of the four maneuvers of Leopold (fundus of uterus, fetal back, fetal head, fetal limbs) are marked on the abdominal surface, guiding users to operate through color or concave-convex design.

[0022] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the drawings.
[0023] It should be noted that all the expressions using "first" and "second" in the embodiments of the present utility model are used to distinguish two entities or parameters with the same name but different identities. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present utility model. This will not be elaborated one by one in the subsequent embodiments.
[0024] The directional and positional terms mentioned in the present utility model, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only with reference to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding the present utility model, rather than a limitation on the protection scope of the present utility model.
[0025] As Figures 1-5 shown, an embodiment of a multifunctional pregnant belly model of the present utility model includes a base 1, a skin layer 2 covering the outside of the base 1, and a function simulation module. Fixing straps 11 for fixing on the waist and abdomen of a person are provided on both sides of the base 1. A placement groove 12 is provided inside the base 1, and a movable simulated fetus 13 is provided in the placement groove 12 for performing fetal heart simulation, four maneuvers of Leopold's palpation simulation, and measurement of fundal height and abdominal circumference. Compared with the existing half-body models, by designing the model as a wearable structure, the present utility model can be directly fixed on the waist and abdomen of students or teaching models, being close to the body posture and examination environment of real pregnant women, which helps students obtain a more real and intuitive clinical examination experience, so as to better understand and master the skills of abdominal examination during pregnancy. By providing a placement groove 12 inside the base 1 and equipped with a movable simulated fetus 13, training on core skills such as fetal heart positioning and fetal position judgment can be carried out, especially suitable for the systematic teaching of the four maneuvers of Leopold's palpation, enhancing students' practical ability and clinical thinking. The model adopts a wearable design, which is convenient to carry out in various teaching scenarios, such as skill training rooms, group teaching, and even remote teaching demonstrations, improving the convenience and coverage of model use. The key positions of the four maneuvers of Leopold's palpation (fundus, fetal back, fetal head, fetal limbs) are marked on the abdominal surface, guiding the user to operate through color or concave-convex design.
[0026] The fixing straps 11 on both sides of the base 1 are fixedly connected by Velcro 14 or quick-release buckles. The fixing method using Velcro 14 or quick-release buckles enables the model to be quickly and firmly fixed on the waist and abdomen of the user, making the wearing and disassembly process more convenient, improving the operation efficiency during teaching; at the same time, it can adapt to students of different body types for wearing, enhancing the versatility and comfort of the model, helping to simulate a more realistic pregnant woman's abdominal state, thereby improving the simulation degree and experience of teaching.
[0027] The function simulation module is disposed inside the simulated fetus 13. The function simulation module includes an ultrasonic sensor or a pressure sensor for simulating the heartbeat and fetal movement of the fetus 13. The ultrasonic sensor or the pressure sensor is located at the heart position of the simulated fetus 13. By arranging the function simulation module inside the simulated fetus 13 and placing the sensor at the heart position, the characteristics of the fetal heartbeat and fetal movement can be reproduced more realistically, enabling students to perceive near-real physiological responses during palpation, improving their mastery of skills such as fetal heart position judgment and fetal movement monitoring. At the same time, advanced sensing devices such as ultrasonic sensors or pressure sensors are used to improve the sensitivity and accuracy of the model's response, enhancing the interactivity and technological content during the teaching process, and enabling students to obtain a more comprehensive and real operation training experience without clinical risks.
[0028] The function simulation module is also provided with a small audio player located inside the simulated fetus 13. The small audio player pre-records real fetal heart sounds and has a volume adjustment function. By pre-recording real fetal heart sounds with the built-in small audio player, students can hear the fetal heartbeat close to the real situation during simulated operations, which helps improve their ability to identify and judge fetal heart sounds. The volume adjustment function makes the audio output more flexible. Whether in a noisy environment or in a teaching scenario that requires delicate listening and discrimination, the volume can be adjusted according to needs to ensure the best presentation of the teaching effect. Integrating the audio player inside the simulated fetus 13 not only does not interfere with the overall structure but also, without sacrificing the realism of the model, increases the feedback information during the operation process, enhancing the overall palpation experience of students and thus promoting the mastery of clinical skills.
[0029] On both sides of the placement groove 12, there are fixing blocks 15 for tightly fitting the simulated fetus 13. Inside the fixing blocks 15, there are rechargeable power sources for supplying power to the function simulation module. On the fixing blocks 15, there are interfaces for charging the rechargeable power sources. The setting of the fixing blocks 15 can make the simulated fetus 13 be placed more firmly in the placement groove 12, preventing loosening or displacement during the operation process, thus ensuring that stable and consistent feedback can be obtained for each palpation and various simulated operations. There are rechargeable power sources inside the fixing blocks 15, providing continuous and stable power support for the function simulation module. This design makes the operation of various functions (such as ultrasonic / pressure sensing, audio playback, etc.) more reliable, and at the same time eliminates the cumbersome external power supply. There are charging interfaces on the fixing blocks 15, enabling fast and convenient power replenishment to ensure sufficient power during teaching and training.
[0030] The skin layer 2 simulates the shape of a pregnant woman's abdomen. A connecting sleeve 21 is provided inside the skin layer 2, and the skin layer 2 is tightly and cooperatively connected to the base 1 through the connecting sleeve 21. Through the tight and cooperative connection between the connecting sleeve 21 and the base 1, the stable connection between the skin layer 2 and the base 1 is achieved. This structure not only ensures the tight fit between all parts, but also facilitates the assembly and disassembly of the model and subsequent cleaning and maintenance. Through the integration of the skin layer 2, the connecting sleeve 21 and the base 1, the model can more comprehensively reproduce the appearance and structural layout of a pregnant woman's abdomen, providing a more comprehensive and realistic practice environment for students and promoting the precise mastery of clinical skills.
[0031] The skin layer 2 is made of elastic medical silicone or thermoplastic polyurethane material, and a lightweight plastic frame or high-density foam is provided inside for maintaining the shape of the model. Using elastic medical silicone or thermoplastic polyurethane material can more realistically reproduce the touch and softness of the skin of a pregnant woman's abdomen, providing a more consistent feel with clinical conditions for students during operations such as palpation. The internal setting of a lightweight plastic frame or filling with high-density foam can effectively maintain the overall shape of the model, avoiding deformation caused by long-term use or repeated touching, so as to ensure that a consistent structure and feedback effect can be provided each time it is used.
[0032] A first magnet 16 is provided on the simulated fetus 13, and a second magnet 17 magnetically connected to the simulated fetus 13 is provided at the bottom of the placement groove 12. By using magnetic connection, the rapid disassembly, assembly and replacement of the simulated fetus 13 can be easily achieved during the teaching process, reducing the complexity of maintenance and adjustment, and improving the applicability and flexibility of the model in various teaching scenarios.
[0033] Buttons 18 for opening, closing and controlling different function simulation modules are provided at the bottom of the base 1. By centrally arranging the control buttons 18 at the bottom of the base 1, centralized management and control of all function simulation modules (such as fetal heart simulation, fetal movement detection, etc.) can be realized, facilitating the operator to quickly start and stop each function and improving the convenience of instrument operation during the teaching process.
[0034] The above-disclosed are only the preferred embodiments of the present utility model, and of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
