Description

Technical Field

[0001] This invention relates to the field of medical model technology, and in particular to a neonatal emergency rescue simulation training device and simulation system. Background Technology

[0002] Neonatal asphyxia is one of the leading causes of neonatal death worldwide. Rapid and correct resuscitation is crucial. Neonatal cardiopulmonary resuscitation (CPR) is an emergency and critical first aid skill applicable to newborns whose heartbeat and breathing have stopped due to asphyxia or other causes. Medical staff are primarily trained in neonatal CPR using mannequins.

[0003] Existing traditional newborn models can only perform mechanical chest compressions and ventilation exercises, and cannot simulate the complex physiological processes of dynamic changes in the body during newborn cardiopulmonary resuscitation. Trainees cannot obtain real-time feedback from the model and lack a sense of immersion.

[0004] Existing models cannot electronically monitor and provide real-time feedback on key indicators such as compression depth, compression frequency, ventilation volume, and ventilation timing, making it impossible for trainees to understand operational errors in a timely manner, and making it difficult for instructors to conduct objective and accurate assessments.

[0005] Furthermore, during cardiopulmonary resuscitation (CPR), the alternation frequency of compressions and ventilations needs to be precisely controlled. If the compression and ventilation frequencies are out of balance, it will affect the effectiveness of emergency treatment and may also lead to additional complications.

[0006] Based on this, the present invention designs a newborn emergency rescue simulation training device and simulation system to solve the above problems. Summary of the Invention

The outer wall of the telescopic column 236 is fitted with... Equipped with a movable rod 237, which slides and rises and falls along the groove, the telescopic column 236 has a transmission column 235 installed at its bottom. A rotating cylinder 238 is rotatably connected inside the transfer cylinder 231, with its top penetrating through and rotatably connected to the transfer cylinder 231.

Three rotating arc plates 239 are installed on the outer wall of the rotating cylinder 238, one of which is connected to the transfer cylinder 231. The inner wall is provided with connection holes 230. When the rotating arc plate 239 with connection holes 230 rotates to the corresponding position of the transfer air cylinder 231, the two connection holes 230 will be connected. The transfer air cylinder 231 is provided with a three-way valve 29. The back plate 26 is equipped with an air pressure sensor 264.

[0055] Specifically, a servo motor 25 is provided inside the shell 21, and an arm 28 is provided at the end of the servo motor 25. A transmission plate 223 is provided outside the rib plate 222. The rotation of the arm 28 periodically drives the transmission plate 223 to push upward. A body skin 211 is provided outside the shell 21. A back pressure sensor 27 is provided outside the back plate 26. The body skin 211 covers the first top plate 243, the chest pressure sensor 221 and the back pressure sensor 27.

[0056] Furthermore, a servo motor 25 is installed inside the shell 21, and an arm 28 is installed at the output end of the servo motor 25. A transmission plate 223 is installed at the bottom of one side of the rib plate 222. The transmission plate 223 passes through the chest plate 224 and is movably connected to the chest plate 224. The arm 28 rotates periodically to drive the transmission plate 223 upward. A body skin 211 is provided on the outside of the shell 21. A back pressure sensor 27 is provided on the outside of the back plate 26. The body skin 211 covers the first top plate 243, the chest pressure sensor 221 and the back pressure sensor 27.

[0057] The system includes a workstation, which comprises hardware, a monitor, and a mouse. The hardware is a hardware terminal with a processor, used to receive monitoring data from the chest pressure sensor 221, back pressure sensor 27, air pressure sensor 264, and Hall sensor 133, and to quantify and display the data on the display screen. It is also used to control the rotational speeds of the first motor 241, the second motor 313, and the servo motor 25, as well as to display the pupil image on the LCD display screen 16.

[0058] When practicing neonatal cardiopulmonary resuscitation, the neonatal model is placed on the operating table. First, air is delivered through the simulated oral cavity 131 of the silicone airway component 13 via intubation or artificial respiration. The delivered air passes through the simulated airway 132 and enters the transfer cylinder 231. At this time, the connection hole 230 on the rotating arc plate 239 with the connection hole 230 inside the transfer cylinder 231 is aligned with the connection hole 230 on the transfer cylinder 231. The gas enters the three-way valve 29 through the hose, and then enters the air bag 20 and the air pressure sensor 264 through the three-way valve 29. The air pressure sensor 264 measures and evaluates the incoming air pressure and displays it in real time on the display screen for the trainee to view and adjust.

[0059] After inhalation, chest compressions are required. The compression-to-inhalation ratio is 3:1, meaning one inhalation is needed after every three compressions. During the first compression, the chest plate 224 rotates with the compression, causing the lifting rod 232 to move downwards. The lifting rod 232 then moves the transmission seat 234 downwards. The two transmission seats 234 move downwards as a whole through the movable cylinder within the positioning cylinder 233. At this time, the movable rod 237, along with the downward movement of the transmission seat 234, presses against the arc surface of the groove on the top transmission seat 234. The movable rod 237 then slides along the arc surface of the groove, causing the telescopic column 236 to rotate. The telescopic column 236 then rotates the transmission column 235, which in turn rotates the rotating arc plate 239. As the compression ends, the chest plate 224 moves upwards, causing the transmission seat 234 to move upwards as a whole. At this point, the movable rod 237 falls into the groove on the bottom transmission seat 234 and is positioned at the bottom of the groove. At this point, the rotating arc plate 239 completes a 120° rotation. Then, with each press, the rotating arc plate 239 rotates once. Only after three rotations can the rotating arc plate 239 with the connecting hole 230 be rotated again to align with the connecting hole 230 on the transfer air cylinder 231. During this process, if the rotating arc plate 239 with the connecting hole 230 is rotated one more or one less time, it will be misaligned with the connecting hole 230 on the transfer air cylinder 231. If air is delivered at this time, the gas will be blocked in the transfer air cylinder 231, and the air pressure sensor 264 and the air bag 20 will not be able to receive the air. If air is delivered by artificial respiration, the obstruction during blowing can be clearly felt, allowing the trainee to promptly notice the error in the frequency of pressing and delivering air and make adjustments. After noticing the error, the rotating arc plate 239 can be rotated to the corresponding position again by continuing to press, so that the transfer air cylinder 231 can be connected.

[0060] During the compression operation, the chest pressure sensor 221 on the top of the rib plate 222 can detect the compression force. At the same time, as the compression continues, the chest plate 224 drives the lifting box 225 to move downward. The lifting box 225 drives the grating 226 to move downward. The photoelectric switch 228 detects the downward movement of the grating 226, thereby quantifying the compression depth and displaying it directly on the display screen. This allows students and instructors to view the depth and pressure of the compression and compare the monitored data for timely adjustments and learning, making the learning more precise.

[0061] As chest compressions and air delivery are performed, if the operation is successful, the terminal hardware activates the servo motor 25 and the first motor 241. The servo motor 25 drives the arm 28 to rotate, lifting the transmission plate 223 upwards to simulate the rise and fall of a newborn's chest during spontaneous breathing. At this time, the trainee can observe this situation in real time and receive feedback of success. During the training process, the trainee can touch the carotid pulse area on the model. The speed of the first motor 241 is adjusted in real time through the control of the hardware terminal. The first motor 241 drives the first cam 242 to rotate, and the first cam 242 drives the first top plate 243 to periodically push upwards to simulate the pulse beat, allowing the trainee to provide first aid feedback through the pulse, increasing realism and immersion.

Both the head shell 11 and the head skin 12 have eye holes 121 with corresponding positions. A circular LCD display screen 16 is installed inside the eye holes 121.

[0065] It should be noted that the LCD display 16 is used to simulate the state of an infant's pupils, which has three states: normal pupil, dilated pupil, and constricted pupil, simulating the dynamic recovery process of the infant's pupils during cardiopulmonary resuscitation.

[0066] Specifically, the oral airway silicone component 13 includes a simulated oral cavity 131 disposed on the head shell 11 and a simulated airway 132 disposed inside the head shell 11 and extending into the body shell 21.

[0067] Furthermore, the oral airway silicone component 13 includes a simulated oral cavity 131 embedded in the head shell 11 and a simulated airway 132 located inside the head shell 11 and extending into the torso shell 21. Hall sensors 133 are symmetrically installed inside the simulated airway 132. The Hall sensors 133 are respectively located in the simulated airway 132 near the inlet of the simulated oral cavity 131 and at the end of the simulated airway 132. During positive pressure ventilation and tracheal insertion, the Hall sensors 133 can dynamically detect the insertion depth of the trachea and monitor the insertion depth. A colored LED light strip is provided on the outside of the simulated oral cavity 131. The colored LED light strip is embedded in the bottom of the head skin 12 and connected to the head PCB board 15. It can gradually change the facial color from cyanosis to a rosy red according to the progress of cardiopulmonary resuscitation, simulating the infant's face gradually recovering from hypoxia to aerobic state during cardiopulmonary resuscitation.

[0068] It should be noted that the head skin 12 is a TPE thermoplastic elastomer blend, which not only has simulated skin elasticity but also allows light to pass through effectively. The light emitted by the colored LED light strip can be clearly observed by the operator through the head skin 12.

[0069] During first aid training, if air is delivered via intubation, the trainee needs to manually tilt the model's head back slightly before intubation. At this time, the angle sensor 151 monitors the angle of the head in real time and displays it quantitatively on the screen, so that the trainee can view it and make quick adjustments based on the displayed data.

[0070] When inserting the trachea, after the air delivery tube is inserted into the simulated oral cavity 131 and into the simulated airway 132, the Hall sensor 133 at the simulated airway 132 monitors the insertion depth of the trachea in real time and displays the monitoring data on the screen, which is convenient for trainees to view and adjust in real time, thus improving the learning effect of intubation.

[0071] Example 3, referring to Figure 9 and Figure 10 This is the third embodiment of the present invention, which differs from the previous embodiment in that it includes a limb component 3.

[0072] Specifically, the limb component 3 includes an arm component 31 rotatably disposed outside the body shell 21. The arm component 31 includes an upper arm bone 312, and a forearm bone 311 is rotatably disposed at the end of the upper arm bone 312. A second motor 313 is disposed inside the upper arm bone 312, and a second cam 314 is disposed at the end of the second motor 313. A second top plate 315 is movably disposed outside the upper arm bone 312. Both the upper arm bone 312 and the forearm bone 311 are provided with colored LED light strips on their exteriors, and both the upper arm bone 312 and the forearm bone 311 are provided with an arm skin 316 covering the colored LED light strips on their exteriors.

[0073] Furthermore, the limb assembly 3 includes an arm component 31 rotatably connected to the outside of the body shell 21. The arm component 31 includes an upper arm bone 312, with ball joints rotatably connected to both sides of the top of the body shell 21 fixed at the upper end of the upper arm bone 312. A forearm bone 311 is rotatably disposed at the end of the upper arm bone 312. The connection between the upper arm bone 312 and the forearm bone 311 is a shaft hole structure. A second motor 313 is installed inside the upper arm bone 312, and a second cam 314 is installed at the output end of the second motor 313. The upper arm bone 312 is externally... An embedded second top plate 315 that can move outward is installed. When the second cam 314 rotates, it periodically pushes the second top plate 315 upward to simulate the pulse beating in a newborn's arm. Both the upper arm bone 312 and the forearm bone 311 are equipped with colored LED light strips. The color of the arm can gradually change from cyanosis to a rosy red according to the progress of cardiopulmonary resuscitation, simulating the gradual recovery of the infant's arm from a hypoxic state to an aerobic state during cardiopulmonary resuscitation. Both the upper arm bone 312 and the forearm bone 311 are fitted with arm skin 316 covered with colored LED light strips.

[0074] Specifically, the limb component 3 also includes a leg component 32, which includes a leg bone 321 rotatably disposed outside the body shell 21. The end of the leg bone 321 is provided with a foot plate 323. A foot pressure sensor 324 is provided outside the foot plate 323. A colored LED light strip is also provided outside the leg bone 321. A leg skin 322 covering the foot pressure sensor 324 and the colored LED light strip is provided outside the leg bone 321.

[0075] Furthermore, the leg component 32 includes a leg bone 321 rotatably connected to the outside of the body shell 21. The upper end of the leg bone 321 is fixed with a ball joint rotatably connected to both sides of the bottom of the body shell 21. A foot plate 323 is installed at the lower end of the leg bone 321. A foot pressure sensor 324 is installed on the outer bottom surface of the foot plate 323. A colored LED light strip is also installed on the outside of the leg bone 321. The color of the leg can gradually change from cyanosis to a rosy red according to the progress of cardiopulmonary resuscitation, simulating the gradual recovery of the infant's leg from a hypoxic state to an aerobic state during cardiopulmonary resuscitation. The leg bone 321 is provided with a leg skin 322 covering the foot pressure sensor 324 and the colored LED light strip.

[0076] It should be noted that the arm skin 316 and the leg skin 322 are both made of TPE thermoplastic elastomer mixed material, which has good simulation effect, and the color of the internal colored LED light strip can be clearly observed.

[0077] In the process of emergency training, in addition to the neck pulse feedback, the pulse at the arm can also be used to obtain real-time feedback from the newborn. The second motor 313 inside the upper arm bone 312 drives the second cam 314 to rotate. When the second cam 314 rotates, it periodically pushes the second top plate 315 outward to simulate the pulse beat, so that the trainees can obtain feedback through the pulse, which improves the realism and immersion.

[0078] During cardiopulmonary resuscitation, if the newborn recovers, it is necessary to pat the soles of the newborn's feet to stimulate spontaneous breathing. When the trainee pats the soles of the feet, the pressure sensor 324 on the soles of the feet is hit and the pressure is quantified and displayed on the screen. The trainee can check whether the operation is qualified based on the data, or adjust the force according to the data and pat again to improve the learning effect.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
