Description

Technical Field

[0001] This invention relates to the field of training device technology, specifically to a simulation device and its control method for intrapartum ultrasound training. Background Technology

[0002] In the medical field, intrapartum ultrasound examination is an important means of managing labor. Medical staff need to have proficient intrapartum ultrasound operation skills. Simulation devices used for intrapartum ultrasound training are educational tools designed to help medical professionals (such as doctors, midwives, and ultrasound technicians) conduct ultrasound examinations in a simulated environment before actual clinical operations. Such simulation devices can provide a safe and controlled practice platform, allowing trainees to become familiar with ultrasound operation skills and diagnostic procedures without risk. Currently, intrapartum ultrasound operation training for medical staff mostly relies on real patients or traditional ultrasound simulators.

[0003] However, relying on real patients poses ethical risks and makes it difficult to guarantee the repeatability of training. Traditional ultrasound simulators can usually only simulate the appearance and basic operating feel of the ultrasound probe, but cannot accurately identify the specific location of the ultrasound probe on the pregnant woman's abdomen, nor can they accurately obtain the angle information of the probe. As a result, it is impossible to call up the corresponding ultrasound video according to the actual position and angle of the probe. The simulation effect is far from that of real intrapartum ultrasound examination, resulting in poor training effect and difficulty in meeting the training needs of medical staff. For some tall people, they need to bend over and look down to observe the screen simultaneously, which can lead to neck and shoulder pain over time. Therefore, we propose a simulation device and its control method for intrapartum ultrasound training. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a simulation device and its control method for intrapartum ultrasound training. By setting an NFC card reader and an angle sensor inside the simulated ultrasound probe, and combining this with an NFC card at the corresponding location inside the pregnant woman's abdominal model, the device can accurately identify the position and angle of the simulated ultrasound probe on the pregnant woman's abdomen, achieving dual precision positioning of position and angle. Through the coordinated setup of the simulated probe and the pregnant woman's abdominal model, trainees only need to move and adjust the simulated probe on the pregnant woman's abdominal model as if operating a real ultrasound probe, without the need for complex operation settings. This makes it highly practical, as users do not need to bend over or look down to simultaneously observe the screen during operation. The display screen is at eye level, reducing the risk of occupational injury and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a simulation device for intrapartum ultrasound training, comprising a base, a support seat slidably connected in a groove opened in the middle of the upper end of the base, a worktable provided in the middle of the right end of the support seat, a simulation probe provided on the front side of the support seat, and further comprising an adjustment mechanism and a simulation mechanism. The simulation mechanism includes an NFC card reader, a pregnant woman's abdomen model, and an NFC card. The NFC card reader is located on the upper side inside the simulation probe, and the pregnant woman's abdomen model is placed on the front side of the base. The control method for the simulation device used for intrapartum ultrasound training includes: The operator holds a simulated probe and moves it close to the surface of a pregnant woman's abdomen model. When the NFC reader approaches the NFC card, the NFC card is activated and transmits data to the NFC reader. The simulated probe reads the data provided by the NFC card through the NFC reader and selects the corresponding video to play based on the different locations sensed. The trainee observes the video and simulates the operation of an intrapartum ultrasound examination.

[0006] The pregnant woman's abdominal model contains NFC cards, simulating the shape and anatomical structure of a real pregnant woman's abdomen. By incorporating an NFC reader and angle sensor within the simulated ultrasound probe, and combining this with the corresponding NFC card within the model, the position and angle of the simulated ultrasound probe on the pregnant woman's abdomen can be accurately identified, achieving precise positioning in both location and angle. Through the coordinated setup of the simulated probe and the pregnant woman's abdominal model, trainees can simply move and adjust the simulated probe on the model as if operating a real ultrasound probe, without complex setup requirements. This makes it highly practical. Users do not need to bend over or look down to simultaneously observe the screen during operation. The display screen is at eye level, maintaining a neutral spinal position, and neck and shoulder pain is less likely to occur even after 2-3 hours of continuous training, reducing the risk of occupational injury.

[0007] Furthermore, the simulation mechanism also includes an angle sensor, which is disposed on the lower side inside the simulation probe; The control method for the simulation device used for intrapartum ultrasound training further includes: At the same location, the angle sensor detects angle data and selects the corresponding video to be played based on different angles at the same location. Trainees can then simulate intrapartum ultrasound examinations by observing the videos.

[0008] Furthermore, the workbench is equipped with a processing module. The NFC card reader and angle sensor are both bidirectionally electrically connected to the processing module, which can integrate and process position information and angle data to generate a matching request signal.

[0009] Furthermore, the system also includes an adjustment mechanism, which comprises an adjustment seat, a mounting plate, a fixed seat, a transmission plate, a bidirectional screw, a servo motor, and a bellows. The adjustment seats are slidably connected to guide grooves located in the middle of the base's bottom wall. The mounting plate is located on the lower side of the support base, and a fixed seat is located at the lower end of the support base. Transmission plates are rotatably connected to the front and rear sides of the lower end of the fixed seat. The upper ends of the two sets of adjustment seats are rotatably connected to the lower ends of vertically adjacent transmission plates. The bidirectional screw is rotatably connected to the lower side inside the base. The adjustment seats are threaded to the front and rear sides of the outer arc surface of the bidirectional screw through threaded holes on their lower front ends. Bellows are provided between the relatively inner sides of the two sets of adjustment seats and between the opposite outer ends of the two sets of adjustment seats and the inner wall of the base. The bellows are sleeved on the outside of the bidirectional screw. A servo motor is located on the lower side of the front end of the base, and the rear end of the servo motor's output shaft is fixedly connected to the front end of the bidirectional screw, enabling the support seat to move.

[0010] Furthermore, a control switch is provided at the upper end of the workbench. The input end of the control switch is electrically connected to an external power supply, the input end of the servo motor is electrically connected to the output end of the control switch, and the input end of the processing module is electrically connected to the output end of the control switch, which can regulate the electrical components inside the equipment.

[0011] Furthermore, a video storage module is provided on the rear side of the bottom wall of the workbench. The video storage module is bidirectionally electrically connected to the processing module and is used to pre-store multiple ultrasound video segments during production.

[0012] Furthermore, it also includes a display module, which is located in the middle of the upper part of the workbench. The input end of the display module is electrically connected to the output end of the processing module, and is used to receive the matching video segment data transmitted by the processing module and display the video segment in real time for trainees to observe the simulated intrapartum ultrasound images.

[0013] Furthermore, the front end of the workbench is provided with a placement rack, and the rightmost placement rack contains a simulation probe, which can prevent the simulation probe from being bumped, squeezed or otherwise physically damaged when not in use.

[0014] Furthermore, the number of NFC cards is no less than four, located in the center, on both sides and at the bottom of the abdomen corresponding to the uterus.

[0015] A control method for a simulation device used for intrapartum ultrasound training includes the following steps: S1. Move the base to the designated work location. There are two self-locking casters on the right side of the lower end of the base and a guide wheel on the left side. During the movement, first close the foot brake of the guide wheel, and then push the base. After the base moves to the designated work location, close the foot brake of the guide wheel again. S2. By controlling the switch, the servo motor starts running. The output shaft of the servo motor drives the bidirectional screw to rotate, and the distance between the two sets of adjustment seats will gradually decrease. During the movement of the adjustment seat, the transmission plate will give the fixed seat an upward thrust, so that the fixed seat drives the display screen to move through the support seat, thereby adjusting the height of the display screen. The operator can move the display screen to a suitable height according to their own situation. S3. By controlling the switch, the processing module starts to run. Then, the operator holds the simulated probe and moves it close to the surface of the pregnant woman's abdomen model. When the simulated probe moves to a certain part, the NFC card reader inside the simulated probe senses the NFC card embedded there. The NFC card is activated and transmits data. The simulated probe reads the data provided by the NFC card through the NFC card reader and finally transmits the data to the processing module. The processing module receives the data sent by the NFC card reader and parses it. Based on the parsed location information, it plays the corresponding video. S4. The angle sensor collects pitch, roll, and yaw angle data of the simulated probe and transmits the detected data to the processing module. The processing module receives the data sent by the angle sensor. After receiving the position code and angle data, the processing module runs the pre-programmed data processing program to parse the position code to determine the current anatomical location of the simulated probe, filters the angle data to remove interference signals, and then integrates them to generate the corresponding request command. The processing module then transmits the request command to the video storage module. After finding the matching video segment, the video storage module plays it through the display module. Trainees can simulate intrapartum ultrasound examination by observing the video on the display module.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This simulation device for intrapartum ultrasound training has the following advantages: 1. By setting up an NFC card reader and angle sensor inside the simulated ultrasound probe, and combining it with the NFC card in the corresponding part of the pregnant woman's abdomen model, the position and angle of the simulated ultrasound probe on the pregnant woman's abdomen can be accurately identified, achieving dual precise positioning of position and angle. Then, the matching ultrasound video segment can be called up. The simulation effect is highly consistent with the actual intrapartum ultrasound examination, effectively improving the authenticity and effectiveness of the training.

[0017] 2. By using a simulated probe and a pregnant woman's abdominal model together, trainees can simply move and adjust the simulated probe on the pregnant woman's abdominal model as if operating a real ultrasound probe, and observe the corresponding simulated ultrasound images in real time. This solves the ethical risks of relying on real patients and the difficulty in ensuring the repeatability of training. It does not require complicated operation settings and is highly practical.

[0018] 3. Through the coordinated design of the adjustable seat and transmission plate, the height of the display screen can be adjusted according to the operator's actual situation, making it suitable for users of different heights. During operation, users do not need to bend over or look down to observe the screen simultaneously. The height of the display screen is at eye level, and even after 2-3 hours of continuous training, neck and shoulder pain is less likely to occur, reducing the risk of occupational injury.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-8This embodiment provides a technical solution: a simulation device for intrapartum ultrasound training, including a base 1, a support seat 2 slidably connected in a groove opened in the middle of the upper end of the base 1, a worktable 3 set in the middle of the right end of the support seat 2, a simulation probe 8 set in the front side of the support seat 2, and self-locking casters set in the four corners of the lower end of the base 1. During the movement, the foot brake of the self-locking casters is first closed, and then the base 1 is pushed. During the movement of the base 1, the self-locking casters reduce the friction between the base 1 and the ground by rolling, so that the base 1 can move more easily. The movable bracket of the self-locking casters allows the wheels to rotate in multiple directions, providing flexible mobility, and also includes a simulation mechanism 9. The simulation mechanism 9 includes an NFC reader 91 and an angle sensor 92. The NFC reader 91 is located on the upper side inside the simulation probe 8, and the angle sensor 92 is located on the lower side inside the simulation probe 8. The NFC reader 91 ensures stable information reading when the simulation probe is close to the pregnant woman's abdominal model. The angle sensor 92 is fixed inside the simulation probe 8 by a snap-fit ​​structure. During the use of the simulation probe 8, the angle sensor 92 first detects the gravitational acceleration of the simulation probe 8, and then calculates the tilt angle of the simulation probe 8, thereby collecting the pitch angle, roll angle, and yaw angle data of the simulation probe 8. By setting the NFC reader 91 and the angle sensor 92 inside the simulation ultrasound probe 8, and combining them with the NFC card 94 in the corresponding part of the pregnant woman's abdominal model 93, the position and angle of the simulation ultrasound probe 8 on the pregnant woman's abdomen 93 can be accurately identified, achieving dual accurate positioning of position and angle. Then, the matching ultrasound video segment can be called. The simulation effect is highly consistent with the actual intrapartum ultrasound examination, effectively improving the authenticity and effectiveness of the training.

[0023] The control method for the simulation device used for intrapartum ultrasound training includes: The operator holds the simulated probe 8 and moves it close to the surface of the pregnant woman's abdomen model 93. When the NFC card reader 91 approaches the NFC card 94, the NFC card 94 is activated and transmits data to the NFC card reader 91. The simulated probe 8 reads the data provided by the NFC card 94 through the NFC card reader 91 and selects the corresponding video to play according to the different positions sensed. At the same position, the angle sensor 92 detects angle data and selects the corresponding video to be played according to different angles at the same position. Trainees can simulate the operation of intrapartum ultrasound examination by observing the video.

[0024] like Figure 4As shown, the workbench 3 is equipped with a processing module 5. The NFC card reader 91 and the angle sensor 92 are both bidirectionally electrically connected to the processing module 5. After receiving the position code and angle data, the processing module 5 runs the pre-programmed data processing program, parses the position code to determine the anatomical location of the current analog probe 8, filters the angle data to remove interference signals, and then integrates them to generate the corresponding request command.

[0025] like Figure 1-3 and Figure 7 It also includes an adjustment mechanism 4, which includes an adjustment seat 41, a mounting plate 42, a fixed seat 43, a transmission plate 44, a bidirectional screw 45, a servo motor 46, and a bellows 47. The adjustment seats 41 are slidably connected to the guide grooves provided in the middle of the bottom wall of the base 1. The mounting plate 42 is provided on the lower side of the support base 2. The lower end of the support base 2 is provided with a fixed seat 43. The front and rear sides of the lower end of the fixed seat 43 are rotatably connected to the transmission plates 44 respectively. The upper ends of the two sets of adjustment seats 41 are rotatably connected to the lower ends of the vertically adjacent transmission plates 44 respectively. The bidirectional screw 45 is rotatably connected to the lower side inside the base 1. The adjusting seats 41 are threaded to the front and rear sides of the outer arc surface of the bidirectional screw 45 through the threaded holes opened on the lower side of their front ends. Corrugated tubes 47 are provided between the opposite inner sides of the two sets of adjusting seats 41 and between the opposite outer ends of the two sets of adjusting seats 41 and the inner wall of the base 1. The corrugated tubes 47 are respectively sleeved on the outside of the bidirectional screw 45. A servo motor 46 is provided on the lower side of the front end of the base 1. The rear end of the output shaft of the servo motor 46 is fixedly connected to the front end of the bidirectional screw 45.

[0026] With this configuration, the drive component provides an upward thrust to the fixed base 43 via the transmission plate 44 during movement, thereby causing the fixed base 43 to move the display screen 7 via the support base 2. The adjustment base 41 and other components are located inside the sealed base 1, thereby adjusting the height of the display screen 7. Through the cooperation of the adjustment base 41 and the transmission plate 44, the height of the display screen 7 can be adjusted according to the actual situation of the operator, making it suitable for users of different heights. During operation, the user does not need to bend over or look down to observe the screen simultaneously. If the height of the display screen 7 is level with the line of sight, it can maintain a neutral spinal position, and even after 2-3 hours of continuous training, acute neck and shoulder pain is less likely to occur, reducing the risk of occupational injury. By controlling the switch 11, the servo motor 46 starts to run, and the output shaft of the servo motor 46 drives the bidirectional screw 45 to rotate. During the rotation of the bidirectional screw 45, it drives the adjustment base 41 to move through the threaded connection.

[0027] like Figure 6As shown, the simulation device 9 also includes a pregnant woman's abdominal model 93 and NFC cards 94. The pregnant woman's abdominal model 93 is placed on the front side of the base 1. NFC cards 94 are installed inside the pregnant woman's abdominal model 93. The pregnant woman's abdominal model 93 is made of medical-grade silicone material to simulate the softness and shape of a real pregnant woman's abdomen in the mid-to-late stages of pregnancy. The interior of the model is set up according to human anatomy to simulate structures such as the uterus and fetus. Positioning lines are marked on the surface of the model corresponding to key anatomical sites in real ultrasound examinations. Passive NFC cards 94 are embedded inside the area enclosed by each positioning line. There are no fewer than 4 NFC cards 94, located in the center, both sides, and the lower part of the abdomen corresponding to the uterus. Each NFC card 94 is fixed with epoxy resin. Through the cooperation of the simulated probe 8 and the pregnant woman's abdominal model 93, the trainee only needs to move and adjust the simulated probe 8 on the pregnant woman's abdominal model 93 as if operating a real ultrasound probe to observe the corresponding simulated ultrasound images in real time. This solves the problem of ethical risks and difficulty in ensuring the repeatability of training when relying on real patients. It does not require complicated operation settings and is highly practical.

[0028] like Figure 1 As shown, a control switch 11 is provided on the upper end of the workbench 3. The input end of the control switch 11 is electrically connected to an external power supply, the input end of the servo motor 46 is electrically connected to the output end of the control switch 11, and the input end of the processing module 5 is electrically connected to the output end of the control switch 11, which can regulate the electrical components inside the equipment.

[0029] like Figure 4 As shown, a video storage module 6 is installed on the rear side of the bottom wall of the workbench 3. The video storage module 6 is bidirectionally electrically connected to the processing module 5. The processing module 5 transmits the request command to the video storage module 6 through the built-in serial communication interface. The video storage module 6 receives the command through the built-in serial communication interface. After receiving the matching request command, the video storage module 6 retrieves the corresponding video file according to the information in the command.

[0030] like Figure 1 As shown, it also includes a display module 7, which is located in the middle of the upper end of the workbench 3. The input terminal of the display module 7 is electrically connected to the output terminal of the processing module 5. The processing module 5 transmits the received video data to the display module 7 through its built-in serial communication port. The display module 7 receives the video data sent by the processing module 5 through its built-in data receiving module. Finally, the display module 7 displays the content. Trainees can simulate intrapartum ultrasound examination by observing the video of the display module 7.

[0031] like Figure 4As shown, the front end of the workbench 3 is provided with a placement rack 10. The rightmost placement rack 10 contains the simulation probe 8. The placement rack 10 can provide a safe storage location for the simulation probe 8, preventing it from being bumped, squeezed or otherwise physically damaged when not in use.

[0032] A control method for a simulation device used for intrapartum ultrasound training includes the following steps: S1. Move the base 1 to the designated work location. The base 1 has two self-locking casters on the right side of its lower end and guide wheels on the left side. During the movement, first close the foot brake on the guide wheels, and then push the base 1. During the movement of the base 1, the self-locking casters and guide wheels reduce the friction between the base 1 and the ground by rolling, so that the base 1 can move more easily. The movable bracket of the self-locking casters allows the wheels to rotate in multiple directions, providing flexible movement capabilities. After the base 1 is moved to the designated work location, close the foot brake on the guide wheels again. S2. By controlling the switch 11, the servo motor 46 starts running. The output shaft of the servo motor 46 drives the bidirectional screw 45 to rotate. During the rotation, the bidirectional screw 45 will drive the adjusting seat 41 to move through the threaded connection. At this time, the bellows 47 in the middle contracts and the bellows 47 on the front and rear sides extend. The bellows 47 can prevent the bidirectional screw 45 from directly contacting the external environment. At this time, the distance between the two sets of adjusting seats 41 will gradually decrease. During the movement, the adjusting seat 41 will give the fixed seat 43 an upward push through the transmission plate 44, so that the fixed seat 43 drives the display screen 7 to move through the support seat 2. The adjusting seat 41 and other components are located in the sealed base 1, thereby adjusting the height of the display screen 7. During the adjustment process, the operator observes the position of the display screen 7 in real time. Then, the operator moves the display screen 7 to a suitable height according to their own situation. S3. During the use of the simulation device for intrapartum ultrasound training, the processing module 5 starts running by controlling the switch 11. Then, the operator holds the simulation probe 8 and moves it close to the surface of the pregnant woman's abdominal model 93. When the simulation probe 8 moves to a certain anatomical location, the NFC reader 91 inside the simulation probe 8 senses the NFC card 94 embedded there. The core component of the NFC card 94 is the antenna, which is usually a small coil. The antenna is used to receive and send wireless signals. When the NFC reader 91 is close to the NFC card 94, the electromagnetic field emitted by the NFC reader 91 will induce a current in the antenna of the NFC card 94. At this time, the NFC card 94 is activated. Then, the NFC card 94 transmits data by changing the amplitude or frequency of the electromagnetic field. After that, the simulation probe 8 reads the data provided by the NFC card 94 through the NFC reader 91, and finally transmits the data to the processing module 5 through the built-in data transceiver module. S4. Processing module 5 receives data sent by NFC reader 91 through its built-in serial communication port. During the use of the simulated probe 8, angle sensor 92 first detects the gravitational acceleration of the simulated probe 8, then calculates the tilt angle of the simulated probe 8, thereby collecting the pitch angle, roll angle, and yaw angle data of the simulated probe 8. Then, angle sensor 92 transmits the detected data to processing module 5 through its built-in data transceiver module. Processing module 5 receives the data sent by angle sensor 92 through its built-in serial communication port. After receiving the position code and angle data, processing module 5 runs the pre-programmed data processing program, parses the position code to determine the current anatomical location of the simulated probe 8, filters the angle data to remove interference signals, and then integrates and generates the corresponding request command. Processing module 5 then sends the request command... The command is transmitted to the video storage module 6 via the built-in serial communication interface. The video storage module 6 receives the command via the built-in serial communication interface. After receiving the matching request command, the video storage module 6 searches for the corresponding video file according to the information in the command. After finding the matching video segment, the video storage module 6 transmits the video data to the processing module 5 via the built-in serial communication interface. The processing module 5 receives the video data via the built-in serial communication interface. Then, under the control of the processing module 5, the display module 7 starts to run. The processing module 5 transmits the received video data to the display module 7 via the built-in serial communication port. The display module 7 receives the video data sent by the processing module 5 through the built-in data receiving module. Finally, the display module 7 displays the content. Trainees can simulate intrapartum ultrasound examination by observing the video on the display module 7.

[0033] It is worth noting that the processing module 5 disclosed in the above embodiments uses a microcontroller based on the ARM Cortex-M4 core, the servo motor 46 can be a 5IK200A-AF, the video storage module 6 uses a 128GB solid-state drive, the display module 7 uses a 10.1-inch high-definition touch screen (1920×1200 resolution), the NFC card reader 91 uses a high-frequency NFC module with an operating frequency of 13.56MHz, and the angle sensor 92 uses a six-axis attitude sensor. The processing module 5 controls the operation of the video storage module 6, the display module 7, the NFC card reader 91, and the angle sensor 92 using methods commonly used in the prior art. The control switch 11 is equipped with switch buttons that correspond one-to-one with the servo motor 46 and the processing module 5 and are used to control their switching.

10. A simulation device for intrapartum ultrasound training according to claim 7, characterized in that, Its control method includes the following steps: S1. Move the base (1) to the designated work location. There are two self-locking casters on the right side of the lower end of the base (1) and a guide wheel on the left side. During the movement, first close the foot brake of the guide wheel, and then push the base (1). After the base (1) moves to the designated work location, close the foot brake of the guide wheel again. S2. By controlling the switch (11), the servo motor (46) starts to run. The output shaft of the servo motor (46) drives the bidirectional screw (45) to rotate. The distance between the two sets of adjustment seats (41) will gradually decrease. During the movement, the adjustment seat (41) will give the fixed seat (43) an upward push through the transmission plate (44), so that the fixed seat (43) drives the display screen (7) to move through the support seat (2), thereby adjusting the height of the display screen (7). The operator can move the display screen (7) to a suitable height according to their own situation. S3. By controlling the switch (11), the processing module (5) starts to run. Then, the operator holds the simulated probe (8) close to the surface of the pregnant woman's abdomen model (93) and moves it. When the simulated probe (8) moves to a certain part, the NFC card reader (91) inside the simulated probe (8) senses the NFC card (94) embedded there. The NFC card (94) is activated and transmits data. The simulated probe (8) reads the data provided by the NFC card (94) through the NFC card reader (91) and finally transmits the data to the processing module (5). The processing module (5) receives the data sent by the NFC card reader (91) and parses it. According to the parsed location information, it plays the corresponding video. S4. Angle sensor (92) collects pitch, roll and yaw angle data of simulated probe (8) and transmits the detected data to processing module (5). Processing module (5) receives the data sent by angle sensor (92). After receiving position code and angle data, processing module (5) runs pre-programmed data processing program, parses position code to determine the anatomical location of simulated probe (8), filters angle data to remove interference signals, and then integrates to generate corresponding request instructions. After that, processing module (5) transmits request instructions to video storage module (6). After finding matching video segments, video storage module (6) broadcasts them through display module (7). Trainees can simulate intrapartum ultrasound examination by observing the video on display module (7).
