Technical Field

[0002] Extracorporeal membrane oxygenation (ECMO) is a mechanical circulatory support device that provides extracorporeal circulation for patients with respiratory failure. In recent years, it has been widely used in the rescue of patients with cardiopulmonary failure. However, its clinical application is limited due to the complexity of this medical technology, the high risk of operation, and the lack of experience among nursing staff.

[0003] Therefore, providing standardized training to trainees on this medical technology can reduce accidents caused by insufficient experience and improper operation among medical staff, thereby improving clinical outcomes. However, current simulation training for ECMO fails to meet expectations; for example, it cannot simulate various medical scenarios, and the simulation scenarios lack realism, resulting in poor overall training effectiveness.

Detailed Implementation

[0048] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0049] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0050] The following description, in conjunction with the accompanying drawings, provides an exemplary illustration of the simulated training device based on extracorporeal membrane oxygenation (ECMO) provided in this disclosure.

[0051] Figure 1 A simulation training device based on extracorporeal membrane oxygenation (ECMO) is provided for embodiments of this disclosure, referring to... Figure 1 The simulation training device includes a dummy body 110, a circulatory simulation component 120, a monitoring simulation component 130, a respiratory simulation component 140, a drug simulation component 150, a urine simulation component 160, and an ultrasound simulation component 170. The circulatory simulation component 120, the respiratory simulation component 140, and the urine simulation component 160 are partially housed within the dummy body 110. The respiratory simulation component 140 is connected to the circulatory simulation component 120 via the monitoring simulation component 130. The drug simulation component 150 and the ultrasound simulation component 170 are connected to the dummy body 110. Contact; circulation simulation component 120 is used to simulate extracorporeal membrane oxygenation; monitoring simulation component 130 is used to adjust and display preset vital signs of the dummy body; respiratory simulation component 140 is used at least to inject target gas into the dummy body 110 based on respiratory rate adjustment; drug simulation component 150 is used to simulate drug injection; urine simulation component 160 is used to simulate urine excretion; ultrasound simulation component 170 is used to simulate ultrasound imaging; wherein, the preset vital signs include at least arterial pressure, venous pressure, heart rate, blood oxygen saturation, pulmonary artery wedge pressure, and body temperature.

[0052] The dummy body 110 is a dummy model used to simulate patients. Specifically, during the simulation training, trainees use various simulation components to operate the dummy body 110, simulating the monitoring and treatment of patients in actual medical scenarios. This avoids the serious consequences caused by improper patient treatment in actual medical scenarios, thereby further improving the safety of simulation training and the trainees' practical skills.

[0053] By partially incorporating the circulation simulation component 120 within the dummy body 110, extracorporeal circulation of a patient can be simulated. For example, the circulation simulation component 120 within the dummy body 110 is used to simulate the entry and exit of blood from the patient's body, while the circulation simulation component 120 outside the dummy body 110 is used to simulate the oxygenation of blood from the patient's body, facilitating the introduction of oxygenated blood into the patient's body. This achieves the simulation of extracorporeal membrane oxygenation (ECMO) for the patient.

[0054] By incorporating a breathing simulation component 140 within the dummy body 110, it is possible to simulate a patient using a ventilator. For example, the breathing simulation component 140 injects target gas into the dummy body 110 at a preset breathing frequency, thereby replacing the patient's breathing and simulating a patient using a ventilator.

[0055] Based on the simulation process described above, it is easy to understand that the urine simulation component 160 extends from inside the dummy body 110 to the outside of the dummy body 110, forming a simulation component partially disposed within the dummy body 110, so as to simulate the patient's discharge of urine from inside the body to the outside; the monitoring simulation component 130 contacts the dummy body 110 through the breathing simulation component 140, and simulates and displays the patient's preset vital signs based on manual adjustment of preset vital signs, such as: the patient's arterial pressure, venous pressure, heart rate, blood oxygen saturation, pulmonary artery wedge pressure, and body temperature; the drug simulation component 150 and the ultrasound simulation component 170 both directly contact the outside of the dummy body 110, thereby simulating the patient's drug injection and ultrasound imaging processes, respectively. The specific details of using the above simulation components to simulate medical scenarios will be explained by example later.

[0056] The simulation training device based on extracorporeal membrane oxygenation (ECMO) provided in this embodiment includes a dummy body 110, a circulation simulation component 120, a monitoring simulation component 130, a respiratory simulation component 140, a drug simulation component 150, a urine simulation component 160, and an ultrasound simulation component 170. The circulation simulation component 120, respiratory simulation component 140, and urine simulation component 160 are partially disposed within the dummy body 110. The respiratory simulation component 140 is connected to the circulation simulation component 120 via the monitoring simulation component 130. The drug simulation component 150 and the ultrasound simulation component 170... The system includes: contact with the dummy body 110; a circulation simulation component 120 for simulating extracorporeal membrane oxygenation (ECMO); a monitoring simulation component 130 for adjusting and displaying preset vital signs of the dummy body; a respiratory simulation component 140 for injecting target gas into the dummy body 110 based on respiratory rate adjustments; a drug simulation component 150 for simulating drug injection; a urine simulation component 160 for simulating urine output; and an ultrasound simulation component 170 for simulating ultrasound imaging. The preset vital signs include at least arterial pressure, venous pressure, heart rate, blood oxygen saturation, pulmonary artery wedge pressure, and body temperature. Therefore, by setting up multiple simulation components, various medical scenarios can be simulated, increasing the realism of the simulation scenarios and further improving the training effect.

[0057] In some embodiments, Figure 2 This is a schematic diagram of another simulated training device based on extracorporeal membrane oxygenation (ECMO) provided in an embodiment of this disclosure. Figure 1 Based on, refer to Figure 2The circulation simulation component 120 includes a circulation controller 121, an extraction pump 122, an oxygenator 123, circulation tubing, and tubing lamps. The circulation controller 121 and the extraction pump 122 are connected. The extraction pump 122 and the oxygenator 123 are both located outside the dummy body 110 and spaced apart in the circulation tubing. A portion of the circulation tubing is located inside the dummy body 110. The tubing lamps are located in the circulation tubing outside the dummy body 110. The circulation tubing is used to circulate simulated blood based on a preset blood oxygenation mode. The extraction pump 122 is used to simulate the heart to introduce simulated blood into the oxygenator 123 through the circulation tubing. The circulation controller 121 is used to control and display the rotation speed, flow rate, and pressure of the circulation tubing of the extraction pump 122. The oxygenator 123 is used to simulate a membrane lung. The tubing lamps are used to turn on and off at a target location based on a preset blood oxygenation mode. The preset blood oxygenation modes include normal oxygenation mode, circulatory oxygenation mode, and hypoxia mode.

[0058] The extraction pump 122 is a structure used to provide extraction power. For example, the extraction pump 122 may be a centrifugal pump, a hand pump, or other structure capable of providing extraction power.

[0059] Specifically, when the extraction pump 122 is a centrifugal pump, the circulation controller 121 can control the speed and flow rate of the centrifugal pump, and simultaneously display the speed, flow rate, and pressure of the circulation pipeline. Furthermore, the circulation controller 121 can further set the flow rate threshold range for the extraction pump 122 and the pressure threshold range for the circulation pipeline. For example, the flow rate threshold range includes a range between the minimum and maximum flow rates. When the flow rate of the extraction pump 122 exceeds the maximum flow rate or falls below the minimum flow rate, the circulation controller 121 issues an alarm message to ensure that the flow rate of the extraction pump 122 remains within the flow rate threshold range. Similarly, the pressure threshold range includes a range between the minimum and maximum pressure. When the pressure in the circulation pipeline exceeds the maximum pressure or falls below the minimum pressure, the circulation controller 121 issues an alarm message to ensure that the pressure in the circulation pipeline remains within the pressure threshold range.

[0060] For example, alarm prompts may include voice prompts, text prompts, or other forms of prompts, which are not limited here.

[0061] It is easy to understand that the circulation controller 121 may be equipped with a control knob for adjusting the speed and flow rate of the centrifugal pump. Specifically, by rotating the control knob for adjusting the speed, the speed of the centrifugal pump will change. At this time, the centrifugal pump will rotate at the set speed to simulate the blood flow of the patient.

[0062] In conjunction with the flow and speed control functions of the circulation controller 121 described above, specifically, the circulation controller 121 can set preset flow and speed matching modes, including: normal matching mode, low flow matching mode, and high flow matching mode. For example, for the normal matching mode, the speed can be set to 2000 r / min, and the corresponding flow rate can be 3 liters. Based on this, for the low flow matching mode, the corresponding flow rate will be lower at the same speed, such as 2 liters at a speed of 2000 r / min, to simulate the situation where the patient's blood flow is small and the flow rate is slow when the patient's blood vessels are obstructed. For the high flow matching mode, the corresponding flow rate will be higher at the same speed, such as 4 liters at a speed of 2000 r / min, to simulate the situation where the patient's blood flow is large and the flow rate is fast when the peripheral vascular resistance is low. Here, the flow rate and speed of the preset flow and speed matching mode are not limited.

[0063] Specifically, in this embodiment of the present disclosure, a centrifugal pump is preferably used as the extraction pump 122 to achieve automatic extraction of simulated blood, thereby improving operational convenience. When the circulation controller 121 malfunctions and cannot control the centrifugal pump to perform automatic extraction, a hand-cranked pump is set as the extraction pump 122 to achieve manual extraction of simulated blood, thus solving the extraction failure problem and enriching the extraction methods of simulated blood.

[0064] It should be noted that the simulated blood is an easy-to-clean simulated blood dye, and its color is black. Correspondingly, the light emission color of the inlet lamp is red. In other embodiments, other colors of dye can be selected according to the light emission color of the inlet lamp, as long as a good simulation effect can be achieved. This is not limited here.

[0065] The circulation tubing is used to simulate blood flow to mimic extracorporeal circulation. Specifically, simulated blood can first be injected into the circulation tubing within the dummy body 110. Then, pump 122, simulating the patient's heart function, extracts simulated blood and introduces it along the circulation tubing into oxygenator 123. Based on this, oxygenator 123 simulates the patient's membrane lung function, using the simulated blood flowing out of oxygenator 123 to simulate the blood flowing through the patient's membrane lung.

[0066] For example, the material of the circulation pipeline can be polyvinyl chloride. In other embodiments, it can also be set to other materials with visual appeal and corrosion resistance, which are not limited here.

[0067] The in-circuit lamps are tubular structures used to demonstrate the flow of simulated blood. Specifically, based on a preset blood oxygenation mode, if the in-circuit lamp is turned on at the target location in the circulation tubing, it emits a preset color of light, such as red. When the simulated blood flows through the target location in the circulation tubing, it appears red under the red light emitted by the lamp. Conversely, for in-circuit lamps that are turned off at other locations, the simulated blood remains black when flowing through the corresponding location in the circulation tubing. Thus, by observing the changes in color intensity during the flow of simulated blood, the flow process of the simulated blood in the circulation tubing can be better observed, achieving a good simulation effect.

[0068] In addition, in this embodiment of the present disclosure, the presence of a thrombus on the patient's membrane lung can be simulated by combining the inlet lamp and the oxygenator 123.

[0069] The preset blood oxygenation modes are used to simulate different oxygenation conditions of the patient's blood. Specifically, the normal oxygenation mode is used to simulate the situation where the patient's blood can be oxygenated normally, the cyclic oxygenation mode is used to simulate the situation where the patient's blood is repeatedly oxygenated after normal oxygenation, and the hypoxia mode is used to simulate the situation where the patient's blood cannot be oxygenated normally. The specific details of the normal oxygenation mode, cyclic oxygenation mode, and hypoxia mode will be explained by example later.

[0070] In some embodiments, continue to refer to Figure 1 and Figure 2 The circulating simulation component 120 also includes a variable temperature water tank 126 and a simulated air-oxygen mixer 127; the variable temperature water tank 126 and the simulated air-oxygen mixer 127 are respectively connected to the oxygenator 123; the variable temperature water tank 126 is used to adjust the temperature of the oxygenator 123; the simulated air-oxygen mixer 127 is used to deliver air and oxygen in a preset mixing ratio to the oxygenator 123.

[0071] It is easy to understand that during actual extracorporeal membrane oxygenation (ECMO), the patient's blood temperature will drop because the blood flows out of the body and is then returned to the body. Therefore, to better simulate the normal body temperature of the patient and to better mimic the flow of simulated blood in the circulation tubing, the variable temperature water tank 126 adjusts the temperature of the oxygenator 123 by using the temperature difference between the water tanks. For example, the temperature of the oxygenator 123 can be adjusted to be between 36℃ and 37.2℃ to achieve a constant temperature.

[0072] For example, the simulated air-oxygen mixer 127 may be equipped with selection buttons for the gas flow rate, gas ratio, and gas concentration of air and oxygen. It can be selected to deliver air and oxygen with a preset mixing ratio to the oxygenator 123 through the ventilation tube at a preset gas flow rate and preset gas concentration, so as to better utilize the oxygenator 123 to simulate the function of the patient's membrane lung, such as the patient's membrane lung is used to absorb oxygen from the blood. Here, the gas flow rate, gas concentration, and preset mixing ratio of air and oxygen are not limited.

[0073] In some embodiments, continue to refer to Figure 1 and Figure 2 The circulation pipeline includes a first connecting pipeline 1241, a second connecting pipeline 1242, a third connecting pipeline 1243, and a fourth connecting pipeline 1244; the first connecting pipeline 1241 includes a first connecting end, and the third connecting pipeline 1243 includes a second connecting end; the first connecting end of the first connecting pipeline 1241 is connected to the second connecting end of the third connecting pipeline 1244 and the second connecting end of the third connecting pipeline 1243; the first connecting end, the second connecting end, and the fourth connecting pipeline 1244 are all disposed within the dummy body 110; the second connecting pipeline 1242 is disposed between the extraction pump 122 and the oxygenator 123. Between; the tubular lamps are installed in the first connecting pipe 1241, the second connecting pipe 1242, and the third connecting pipe 1243 outside the dummy body 110; the tubular lamp in the first connecting pipe 1241 is used to turn off based on normal oxygenation mode or hypoxia mode, or to turn off after a preset time based on cyclic oxygenation mode; the tubular lamp in the second connecting pipe 1242 is used to turn off based on normal oxygenation mode, cyclic oxygenation mode, or hypoxia mode; the tubular lamp in the third connecting pipe 1243 is used to turn on based on normal oxygenation mode or cyclic oxygenation mode, or to turn off based on hypoxia mode.

[0074] In conjunction with the pressure of the circulation pipeline mentioned above, specifically, the pressure of the circulation pipeline includes the pressure of the first connecting pipeline 1241, the pressure of the second connecting pipeline 1242, and the pressure of the third connecting pipeline 1243.

[0075] The extraction pump 122 is located between the first connecting pipe 1241 and the second connecting pipe 1242, and the oxygenator 123 is located between the second connecting pipe 1242 and the third connecting pipe 1243. For example, with... Figure 2 Taking the structure shown as an example, the first connecting end of the first connecting pipe 1241 is connected to one end of the fourth connecting pipe 1244, and the second connecting end of the third connecting pipe 1243 is connected to the other end of the fourth connecting pipe 1244.

[0076] Specifically, for the normal oxygenation mode, the tube lights in the first connecting tube 1241 and the second connecting tube 1242 will be turned off, and the tube light in the third connecting tube 1243 will be turned on. At this time, the simulated blood appears black in the first connecting tube 1241 and the second connecting tube 1242, and red in the third connecting tube 1243, to simulate the scenario of the patient's blood not being oxygenated before flowing through the membrane lung and being oxygenated after flowing through the membrane lung.

[0077] In the circulating oxygenation mode, the lamp in the first connecting pipe 1241 will be turned on for a preset time and then off. This includes: the lamp gradually turns on and illuminates along the direction from the dummy body 110 to the extraction pump 122, and the lamp turns off after a preset time, such as 1 second. At the same time, the lamp in the second connecting pipe 1242 turns off, and the lamp in the third connecting pipe 1243 turns on. At this time, a line of red simulated blood can be observed to quickly pass through the first connecting pipe 1241 to simulate the scenario where the patient's blood is not returned to the body for use normally and is drawn back into the circulating pipe.

[0078] It should be noted that the preset time is related to the patient's heart rate. For example, for patients with normal heart rates, the preset time can be set to 1 second. The preset time can be set to other values ​​according to the patient's heart rate, which is not limited here.

[0079] In the hypoxia mode, the first connecting line 1241, the second connecting line 1242, and the third connecting line 1243 are all closed. At this time, the simulated blood in the first connecting line 1241, the second connecting line 1242, and the third connecting line 1243 are all black to simulate the scenario where the patient's membrane lung has oxygenation impairment, such as the formation of blood clots.

[0080] In some embodiments, continue to refer to Figure 1 and Figure 2 The circulation simulation component 120 also includes a clamping element 128, a clamping sensor, and a vibration element 03; the clamping sensor is disposed in the third connecting pipe 1243 and is communicatively connected to the circulation controller 121; the clamping element 128 is located outside the third connecting pipe 1243 and close to the second connecting end; the vibration element 03 is located outside the fourth connecting pipe 1244 and close to the first connecting end; the clamping element 128 is used to clamp the third connecting pipe 1243 to make the flow rate of the circulation pipe zero; the clamping sensor is used to sense the flow rate after the circulation pipe is clamped and send the sensing information to the circulation controller 121; the vibration element 03 is used to control the vibration of the circulation pipe based on the in vivo dehydration mode.

[0081] For example, with Figure 2Taking the orientation and structure shown as an example, along the flow direction of simulated blood, the clamping element 128 is located near the rear end of the third connecting pipe 1243 (corresponding to the second connecting end) to avoid crushing the pipe lamp tube, and the vibration element 03 is located near the rear end of the fourth connecting pipe 1244 and close to the first connecting end; for example, the clamping element 128 can be a pipe wrench or other type of clamp, and the vibration element 03 can be a vibrator or other type of vibration structure, which are not limited here.

[0082] It is easy to understand that when the flow rate of the pump 122 controlled by the circulation controller 121 is zero, the simulated blood will still flow temporarily due to the pressure difference in the circulation pipeline. To address this, when the clamping element 128 clamps the third connecting pipeline 1243, the flow of simulated blood in the entire circulation pipeline will immediately stop. At the same time, the clamping sensor in the third connecting pipeline 1243 will sense that the current flow rate of the circulation pipeline is zero and send this sensing information to the circulation controller 121 so that the circulation controller 121 can display the current flow rate of the circulation pipeline. In this way, precise control of the flow rate of simulated blood in the circulation pipeline is achieved. The specific type and placement of the clamping sensor are not limited here.

[0083] For example, the clamping sensor and the circulation controller 121 can communicate wirelessly. For instance, the clamping sensor and the circulation controller 121 can communicate via a local area network such as Wi-Fi or Bluetooth, or via a wide area network such as 4G or 5G, or via other wireless transmission methods known to those skilled in the art, which are not limited here.

[0084] The in vivo dehydration mode is used to simulate dehydration caused by a patient's lack of water. Specifically, in the in vivo dehydration mode, the vibration element 03 can be controlled by relevant control components such as subsequent scene parameter control components to vibrate, which in turn causes the circulation pipeline outside the dummy body 110 to shake. At the same time, the circulation controller 121 will display the fluctuating flow rate due to the shaking of the circulation pipeline, thus simulating the scenario of a patient's dehydration.

[0085] In some embodiments, Figure 3 This is a schematic diagram of the structure of another simulated training device based on extracorporeal membrane oxygenation provided in the embodiments of this disclosure. Figure 1 and Figure 2 Based on, refer to Figure 3The simulation training device also includes a scenario parameter control component 180; the cyclic simulation component 120 and the monitoring simulation component 130 are both connected to the scenario parameter control component 180; the scenario parameter control component 180 is used to select a simulation scenario and set the initial parameters of the components under the simulation scenario; wherein, the simulation scenario includes at least an in vivo dehydration mode and a preset blood oxygenation mode; the initial parameters of the components include at least the initial rotation speed and initial flow rate corresponding to the cyclic simulation component 120, and the initial vital signs corresponding to the monitoring simulation component 130.

[0086] The scene parameter control component 180 is equipped with application software (APP) for the simulation scene and component initial parameters. The application software communicates and interacts with at least the loop simulation component 120 and the monitoring simulation component 130. Correspondingly, the scene parameter control component 180 is also equipped with a touch screen. By clicking the application software on the touch screen, the selection of the simulation scene and the setting of the component initial parameters can be further realized.

[0087] Specifically, regarding the working principle of the scenario parameter control component 180, before using the simulation training device, the application software on the scenario parameter control component 180 can be used to select a simulation scenario. For example, the software operation interface on the touch screen can display various simulation scenario selection information, including simulation scenario selection information for in vivo dehydration mode and preset blood oxygenation mode. Afterwards, by clicking to select any simulation scenario, the software interface can present the initial parameters of the components for the selected simulation scenario, thereby completing the initialization settings of the relevant components (circulatory simulation component 120 and monitoring simulation component 130) so that trainees can conduct simulation training according to each simulation scenario.

[0088] In this embodiment of the disclosure, the scene parameter control component 180 can also be connected to the urine simulation component 160 and the ultrasound simulation component 170 to control the urine discharge rate of the urine simulation component 160 and the ultrasound image of the ultrasound simulation component 170. For example, regarding the selection of the in vivo dehydration mode, the monitoring simulation component 130 will display a lower central venous pressure and a faster heart rate. The vibration element 03 in the circulation simulation component 120 will operate, causing vibration in the circulation tubing. The circulation controller 121 will display fluctuating flow rates. Simultaneously, the urine discharge rate of the urine simulation component 160 will slow down, and the ultrasound image of the ultrasound simulation component 170 will show the inferior vena cava as narrowed, etc.

[0089] For example, regarding the selection of the preset blood oxygenation mode, taking the circulatory oxygenation mode as an example, the monitoring simulation component 130 will display that the venous blood oxygen saturation is high, the arterial blood oxygen saturation is low, and the heart rate is fast. At the same time, the tube lamp in the first connecting tube 1241 will be turned on for a preset time and then turned off.

[0090] In some embodiments, continue to refer to Figure 1 and Figure 2 The breathing simulation component 140 includes a simulated ventilator 141 and a simulated lung 142; the simulated lung 142 is located inside the dummy body 110; the simulated ventilator 141 is located outside the dummy body 110 and connected to the simulated lung 142; the simulated ventilator 141 is used to adjust and display the breathing rate and breathing pressure for the dummy body 110, and to inject target gas into the simulated lung 142 based on the breathing rate.

[0091] Specifically, the respiratory rate and respiratory pressure are adjusted by the simulated ventilator 141 and the target gas is injected into the simulated lung 142, so that the simulated lung 142 can respond to the fluctuations of the simulated ventilator 141 to simulate the situation where a patient uses a ventilator to improve their own respiratory function.

[0092] For example, the simulated ventilator 141 can adjust the respiratory rate, respiratory pressure and positive end-expiratory pressure, and inject a target gas such as oxygen into the simulated lung 142 at regular intervals according to the adjustment of the respiratory rate. At the same time, the simulated ventilator 141 can display the current respiratory rate, respiratory pressure and the flow rate of the injected target gas on the ventilator display screen, such as displaying relevant flow rate curves and pressure curves.

[0093] In addition, the simulated lung 142 can also simulate the condition of the lungs in the patient's body. For example, the simulated lung 142 can have storage and discharge structures for various secretions, lung blood color dye and transparent color dye. At the same time, the simulated lung 142 can also be equipped with a tube connected to it, which is used to discharge the relevant secretions through the tube, so as to better simulate the condition of the patient's lungs.

[0094] In some embodiments, the monitoring simulation component 130 includes an operating console 131 and a monitor 132; the circulation controller 121, the simulated lungs 142, and the monitor 132 are respectively connected to the operating console 131; the operating console 131 is used to adjust the display data of the monitor 132; the monitor 132 is used to display the preset vital signs of the dummy body 110.

[0095] Specifically, the monitor 132 can display arterial pressure waveforms, central venous pressure waveforms, heart rate waveforms, oxygen saturation waveforms for the left and right hands, venous oxygen saturation, pulmonary artery wedge pressure, and body temperature. It should be noted that arterial pressure includes systolic pressure, diastolic pressure, mean pressure, and intra-aortic balloon pump (IABP) pressure; venous oxygen saturation corresponds to the venous oxygen saturation at the first connecting tubing 1241.

[0096] For example, the control panel 131 can adjust the displayed data of the monitor 132 according to the student's simulated operation. For instance, when the student measures the body temperature of the dummy 110, the control panel can determine whether the student's temperature measurement operation is standard and correct, thereby adjusting the body temperature displayed on the monitor 132. This includes: when the student's measurement action is not standard, the body temperature displayed on the monitor 132 will be slightly lower, while when the student's measurement action is standard, the body temperature displayed on the monitor 132 will be slightly higher. Or, when simulating a patient experiencing dehydration, the student will perform dehydration treatment on the dummy 110. The control panel can determine whether the student's dehydration treatment operation is standard and correct, thereby adjusting the central venous pressure waveform and heart rate displayed on the monitor 132. This includes: when the student's dehydration treatment operation is incorrect, the central venous pressure displayed on the monitor 132 will still be low and the heart rate will be fast, while when the student's dehydration treatment operation is standard, the central venous pressure and heart rate displayed on the monitor 132 will both return to normal levels. In other embodiments, other preset vital signs can also be adjusted and displayed according to other simulated operations of the student, which will not be elaborated here.

[0097] Thus, based on the trainee's simulated operation, the monitor 132 is adjusted using the control panel 131 to provide timely evaluation and feedback on the trainee's simulated operation. At the same time, the monitor 132 displays preset vital signs, making it easy for the trainee to check whether their simulated operation is standard and correct.

[0098] In some embodiments, continue to refer to Figure 1 and Figure 2 The drug simulation component 150 includes a drug injection pump; the drug injection pump is used to inject a preset type and concentration of simulated drug into the dummy body 110 at a preset injection speed.

[0099] The drug infusion pump is a micro-infusion pump. For example, the micro-infusion pump can be set with a preset type, concentration, and preset injection speed of the simulated drug during injection. By injecting the simulated drug of the preset type and concentration into the dummy body 110 at the preset injection speed, the patient's drug injection situation is simulated. In addition, the preset type, concentration, and preset injection speed of the simulated drug can be set according to the simulation training needs. It is only necessary to replenish the simulated drug in a timely manner, and there are no limitations on these settings.

[0100] In some embodiments, continue to refer to Figure 1 and Figure 2 The urine simulation component 160 includes a connected liquid storage bag and a urine storage bag (not shown in the figure); the liquid storage bag is located inside the dummy body 110; the urine storage bag is located outside the dummy body 110; the liquid storage bag is used to discharge simulated urine into the urine storage bag at a preset discharge rate.

[0101] The preset discharge speed can be normal discharge speed, high speed, low speed, or zero speed. For example, when the reservoir bag inside the dummy body 110 discharges simulated urine into the urine storage bag at the normal discharge speed, the reservoir bag can discharge 100 ml of simulated urine into the urine storage bag per hour; if the reservoir bag inside the dummy body 110 discharges simulated urine at zero speed, it indicates that no simulated urine is discharged at this time; here, the specific speed values ​​for normal discharge speed, high speed, and low speed are not limited.

[0102] It is easy to understand that the urine collection bag is a closed bag with a visible effect, so as to intuitively display the total amount of simulated urine. In this way, by using the collection bag to discharge simulated urine into the visible urine collection bag, the patient's urine discharge situation is better simulated.

[0103] For example, the simulated urine may be water or other liquids, and no specific type of simulated urine is limited herein.

[0104] In some embodiments, continue to refer to Figure 1 and Figure 2 The ultrasound simulation component 170 includes an ultrasound probe, an in vivo section sensor, and an ultrasound display screen (not shown in the figure); the in vivo section sensor is positioned at the test location on the dummy body 110; the ultrasound probe is used to approach the in vivo section sensor to simulate ultrasound imaging; and the ultrasound display screen is used to display preset ultrasound images.

[0105] The in-body cross-sectional sensors include a four-chamber heart sensor, a right chest cavity sensor, and a lower limb blood vessel sensor, which are respectively installed on the dummy body 110 at the locations corresponding to the patient's four-chamber heart, right chest cavity, and lower limb blood vessels.

[0106] The preset ultrasound images are manually adjusted and set. Specifically, by bringing the ultrasound probe close to the in-body section sensor, for example, when it is close to the right chest cavity sensor, the ultrasound display screen simulates the preset ultrasound image of the right chest cavity; or, when it is close to the lower limb blood vessel sensor, the ultrasound display screen simulates the preset ultrasound image of the lower limb blood vessels, thus more realistically simulating the patient's ultrasound imaging situation.

[0107] In some embodiments, Figure 1 and Figure 2 Based on, refer to Figure 3 The simulation training device also includes a simulated chest compression component 190 and a simulated defibrillation component 200.

[0108] Specifically, continue to refer to Figure 1 and Figure 2When the circulation controller 121 is connected to the centrifugal pump, if the circulation controller 121 malfunctions, the centrifugal pump will be removed and replaced with a hand pump. In order to simulate the situation of continuing to maintain the patient's life, the simulated chest compression component 190 can be used to perform temporary chest compressions on the dummy body 110 before replacing the hand pump, and the chest compressions on the dummy body 110 will be stopped after replacing the hand pump.

[0109] It is easy to understand that the simulated defibrillation component 200 is used to simulate a patient experiencing ventricular fibrillation for emergency treatment. For example, the simulated defibrillation component 200 can be used to apply an electric current to the dummy body 110. The specific operation process of the simulated defibrillation component 200 will not be described in detail here, but can be understood based on the principle of defibrillation.

[0110] The simulation training device based on extracorporeal membrane oxygenation provided in this disclosure can simulate various medical scenarios by setting up a variety of simulation components, making the simulation of various medical scenarios more realistic and better meeting the needs of simulation training.
