Description

Technical Field

[0001] The present application relates to the field of medical model teaching, and in particular to a malignant hyperthermia clinical skill training simulation dummy and a method of using the same. Background Art

[0002] Malignant Hyperthermia (MH) is a rare but potentially life-threatening condition that is often associated with the use of certain anesthetic drugs. It is an inherited disease that primarily affects skeletal muscle cells, causing a dramatic increase in body temperature and metabolic rate. The condition is triggered when patients are exposed to certain anesthetic drugs, such as volatile anesthetics, such as succinylcholine.

[0003] MH is mainly manifested by systemic muscle spasms, a sharp and continuous increase in body temperature, a rapid increase in oxygen consumption, and CO 2 Produced in large quantities, symptoms such as respiratory and metabolic acidosis occur.

[0004] When judging whether a patient has malignant hyperthermia, the CGS scale of the clinical diagnostic standard is generally used for judgment, such as Figure 1 As shown. When judging malignant hyperthermia, elevated body temperature is one of the important criteria for judging whether a patient has malignant hyperthermia. Almost all malignant hyperthermia will have the symptom of elevated body temperature. However, spinal cord injury (SCI) above the sixth thoracic vertebra is associated with dysfunction of the sympathetic / parasympathetic nerve pathway, including dysfunction of thermoregulation, which manifests as hypothermia due to vasodilation and heat loss in a cold environment. Thermoregulation dysfunction caused by spinal cord injury may mask the early diagnosis of MH and lead to fatal outcomes.

[0005] However, due to the small number of cases and the obvious lack of clinical practice resources, it is difficult for students, interns or practicing physicians to master the skills of determining whether a disease is malignant hyperthermia. Based on this, the present application proposes a malignant hyperthermia clinical skill training simulation dummy and its use method to solve the above technical problems. Summary of the invention

[0006] In order to help personnel learn and master the skill of determining whether a certain disease is malignant hyperthermia, the present application provides a malignant hyperthermia clinical skill training simulation dummy and a method of using the same.

[0007] The present application provides a malignant hyperthermia clinical skill training simulation dummy and a method of using the same, which adopts the following technical solutions: First aspect A malignant hyperthermia clinical skill training simulation dummy, comprising: Simulation human body model; A heart simulator, arranged in the left ventricle of the simulated human body model, for simulating symptoms of arrhythmia; A stiffness simulator, arranged at the joints of the simulation mannequin, for simulating symptoms of muscle stiffness; A thermometer, arranged at the throat of the simulated human model, for simulating symptoms of elevated body temperature; A carbon dioxide exhalation simulator, arranged in the throat of the simulation mannequin, for simulating the symptom of increased carbon dioxide partial pressure at the end of exhalation; A gas inhalation detector is arranged in the throat of the simulated human body model; A control module electrically connected to the heart simulator, the stiffness simulator, the temperature meter, the carbon dioxide exhalation simulator and the gas inhalation detector; Among them, the gas inhalation detector is used to inhale gas and detect the anesthetic content in the gas. If a certain amount of anesthetic is detected, the gas inhalation detector sends a signal to the control module, and the control module controls the heart simulator, stiffness simulator, thermometer, and carbon dioxide exhalation simulator to show corresponding symptoms respectively.

[0008] By adopting the above technical solution, when the gas inhalation detector detects a certain amount of anesthetics, it will trigger other simulators to show corresponding symptoms through the control module, thereby helping learners understand and master the triggering mechanism of malignant hyperthermia; the control module can accurately control each simulator to achieve a true and accurate simulation of the symptoms, which helps learners to accurately recognize the various symptoms of malignant hyperthermia, and help learners to accurately identify malignant hyperthermia in subsequent clinical practice and treat patients in a timely manner.

[0009] Optionally, the simulation dummy further includes a spine simulator arranged on the back of the simulation human model and temperature sensors arranged at the limbs of the simulation human model, the spine simulator and the temperature sensor are both electrically connected to the control module, and the spine simulator is connected to an evoked potential detector; Among them, the control module can control whether the spine simulator sends a specific signal; a low temperature environment is applied to the limbs of the simulated human body model, the temperature sensor obtains temperature information and sends a signal to the control module, the control module sends a signal to the spine simulator, and the spine simulator sends a specific signal to the evoked potential detector, so that the evoked potential detector can display the potential map of spinal injury. If the spine simulator does not send a specific signal to the evoked potential detector, the evoked potential detector displays a normal potential map of the spine.

[0010] By adopting the above technical solution, the body temperature regulation dysfunction caused by spinal cord injury may mask the early diagnosis of MH. Therefore, before anesthesia, low temperature stimulation is applied to the limbs, and then the spinal simulator is tested with an evoked potential detector to determine whether the simulated dummy has the symptom of body temperature regulation dysfunction caused by spinal cord injury. If this symptom exists, in the early stage of anesthesia, it is necessary to consider the problem that the patient's body temperature will not rise. At this time, it is necessary to test the patient more carefully so that the symptoms of malignant hyperthermia can be accurately diagnosed, so that treatment measures can be taken in time. The simulation dummy of the present application scheme can simulate the symptom scenario of patients with body temperature regulation dysfunction caused by spinal cord injury. For patients with this type of special symptoms, it helps learners to learn and recognize the symptoms, which helps to identify the special symptoms in subsequent clinical processes, so that treatment measures can be taken in time to ensure the safety of patients' lives.

[0011] Optionally, the thermometer is electrically connected to the spine simulator; when the control module controls the spine simulator to send a specific signal, the control module sends a low-temperature signal to the thermometer to make the thermometer simulate normal body temperature characteristics.

[0012] By adopting the above technical solution, when the dummy simulates the symptom of temperature regulation dysfunction, the dummy's body temperature will be adjusted accordingly during the subsequent anesthesia operation to simulate the real symptom manifestation, allowing learners to have a deeper understanding of the manifestation of this special disease.

[0013] Optionally, the step of applying a low temperature environment to the limbs of the simulated human body model includes applying a low temperature environment to the limbs of the simulated human body model through a temperature regulating sleeve, wherein the temperature regulating sleeve can be mounted on the limbs of the simulated human body model, and the temperature inside the temperature regulating sleeve can be adjusted.

[0014] By adopting the above technical solution, the limbs of the simulated human model can be quickly stimulated through the temperature regulating sleeve, and combined with the evoked potential detector, it is possible to quickly diagnose whether the simulated dummy has the symptom of temperature regulation dysfunction caused by spinal cord injury, which is helpful for the subsequent diagnosis and treatment of malignant hyperthermia.

[0015] Optionally, an artery is provided in the arm of the simulated human body model, and a high-potassium liquid is contained in the artery. A high-potassium liquid concentration controller is provided in the artery, and the high-potassium liquid concentration controller is electrically connected to the control module.

[0016] By adopting the above technical solution, learners can further diagnose malignant hyperthermia based on the concentration of high potassium fluid.

[0017] Optionally, the simulation dummy further includes a tremor simulator, which is disposed in the simulation human body model and is used to simulate muscle tremor symptoms, and the tremor simulator is electrically connected to the control module.

[0018] By adopting the above technical solutions, learners can further understand and identify the corresponding symptoms of malignant hyperthermia.

[0019] Optionally, the simulation dummy further includes a vein disposed on the hand of the simulation human model, the vein being used to contain a dantrolene sodium liquid, a dantrolene sodium detector being disposed in the vein, and the dantrolene sodium detector being electrically connected to the control module; Among them, the dantrolene sodium detector can obtain the dantrolene sodium concentration value in the vein, and the control module controls the heart simulator, stiffness simulator, thermometer, and carbon dioxide exhalation simulator to simulate different degrees of symptom manifestation according to the dantrolene sodium concentration value.

[0020] By adopting the above technical solutions, in addition to enabling learners to diagnose malignant hyperthermia, they can also provide treatment teaching for malignant hyperthermia, thereby enhancing their practical operation capabilities and clinical response experience.

[0021] Optionally, the armpits, chest and groin of the simulated human body model are provided with cooling sensors, and the cooling sensors are electrically connected to the control module; Among them, the cooling sensor can obtain the temperature values ​​of the armpits, chest and groin, and the control module controls the thermometer to simulate normal body temperature symptoms after a preset time according to the temperature values.

[0022] By adopting the above technical solution, simulating the cooling treatment step can help learners further master the treatment measures for malignant hyperthermia.

[0023] Second aspect A method for using a malignant hyperthermia clinical skill training simulation dummy comprises the following steps: S1. Passing a certain amount of anesthetic gas into the throat of the simulated human body model, the gas inhalation detector inhales the gas and detects the anesthetic content in the gas. When the detected anesthetic content reaches a certain value, the control module controls the heart simulator, the stiffness simulator, the thermometer, and the carbon dioxide exhalation simulator to respectively show corresponding symptoms; S2. The learner uses appropriate instruments or actions to check the symptoms displayed by the simulated dummy; S3. The learner diagnoses whether the simulated dummy suffers from malignant hyperthermia based on the symptoms detected.

[0024] Optionally, after step S3, the method further includes: S4. The instructor shall judge and guide the learners on the order of symptom examination, examination actions and diagnostic results.

[0025] By adopting the above technical solution, the simulation dummy of the present invention can provide comprehensive malignant hyperthermia treatment training to medical students and medical workers, thereby improving their practical operation skills and coping abilities.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0035] The following is combined with Figure 2-4 This application is described in further detail.

[0036] Example 1 The present application embodiment discloses a malignant hyperthermia clinical skills training simulation dummy. Figure 2 The simulation dummy includes a simulation human body model 10 , a heart simulator 20 , a stiffness simulator 21 , a thermometer 22 , a carbon dioxide exhalation simulator 23 , a gas inhalation detector 24 and a control module 30 .

[0037] Optionally, the skin of the simulated human model 10 can be molded by silicone rubber or thermoplastic elastomer, the subcutaneous tissue of the simulated human model 10 can be composed of thin sponge, and the skeleton of the simulated human model 10 can be made of resin or plastic.

[0038] Among them, the heart simulator 20 is installed in the left ventricle of the simulation human model 10 to simulate arrhythmia symptoms. Optionally, the heart simulator 20 can use a bio-robotic heart created by researchers at the Massachusetts Institute of Technology, combining a biological heart and a silicone robotic pump. This simulator can simulate the structure, function and movement of a healthy or diseased heart, allowing surgeons and researchers to demonstrate various interventions while collecting real-time data. The system uses an air-driven silicone soft robotic pump system to replace the myocardium in the left ventricle, which can simulate the beating of the heart and blood flow.

[0039] Similarly, the stiffness simulator 21 is installed at the joint of the simulation mannequin 10 to simulate the symptoms of muscle stiffness. Optionally, the stiffness simulator 21 can be a locking mechanism at the joint of the simulation mannequin 10, and the locking or unlocking of the locking mechanism can be used to show the characteristic of muscle stiffness. The locking mechanism can be a hinged locking mechanism commonly found on the market.

[0040] The thermometer 22 is installed at the throat of the simulation mannequin 10 to simulate the symptom of a short-term temperature rise. Optionally, the thermometer 22 can be a common heater, which is used to raise the temperature of the throat to between 39-43° C. to simulate the symptom of high fever.

[0041] The carbon dioxide exhalation simulator 23 is used to simulate the symptom of increased carbon dioxide partial pressure at the end of exhalation. Optionally, the carbon dioxide exhalation simulator 23 can use a breathing simulator on the market, which contains gas with a carbon dioxide partial pressure greater than 55 mmHg. Specifically, the breathing simulator can be installed outside the simulation mannequin 10 and connected to the throat of the simulation mannequin 10 by a trachea to simulate the symptom of increased carbon dioxide partial pressure at the end of exhalation from the throat.

[0042] The gas inhalation detector 24 is used to inhale gas and detect the anesthetic content in the gas. Optionally, the anesthetic can be succinylcholine, which is a volatile gas. The action of inhaling gas can be achieved by an inhalation device, which is used to introduce the gas into the conductivity detector. The inhalation device can be specifically a suction pump. The conductivity detector can measure the succinylcholine content in the gas using ion chromatography. The conductivity detector can be installed outside the simulation human body model 10, and the conductivity detector and the inhalation device are connected by a trachea.

[0043] In this embodiment, the exhalation end of the carbon dioxide exhalation simulator 23 and the inhalation end of the gas inhalation detector 24 can be connected by the same trachea, and the tracheal tube mouth extends from the throat to the oral cavity. A three-way valve can be set at the connection between the exhalation end of the carbon dioxide exhalation simulator 23 and the inhalation end of the gas inhalation detector 24 to ensure that the gas flows along a preset trajectory. When it is necessary to simulate symptoms, the trachea of ​​the anesthesia machine is docked with the tracheal tube mouth, and the anesthesia machine is used to introduce anesthetic gas into the trachea. The anesthetic gas is inhaled and detected by the gas inhalation detector 24 to trigger the simulation action of each simulator, and the carbon dioxide gas exhaled by the carbon dioxide exhalation simulator 23 can be introduced into the anesthesia machine through the trachea, and the anesthesia machine detects the carbon dioxide gas. The anesthesia machine is a prior art and will not be described in detail here. This process can simulate the human breathing process, and can truly simulate the actual detection process of the patient, which is more conducive to in-depth learning for medical staff.

[0044] The control module 30 can be installed at any position in the simulation mannequin 10, and the control module 30 is electrically connected to the heart simulator 20, the stiffness simulator 21, the body temperature monitor 22, the carbon dioxide exhalation simulator 23, and the gas inhalation detector 24. When the gas inhalation detector 24 detects a certain amount of anesthetic, the gas inhalation detector 24 sends a signal to the control module 30, and the control module 30 controls the heart simulator 20, the stiffness simulator 21, the body temperature monitor 22, and the carbon dioxide exhalation simulator 23 to respectively show corresponding symptoms.

[0045] In addition, the simulation dummy also includes an artery 25 and a tremor simulator 26. The artery 25 is arranged in the arm of the simulation human model 10. The artery 25 contains high potassium liquid. The artery 25 is provided with a high potassium liquid concentration controller, and the high potassium liquid concentration controller is electrically connected to the control module 30. Optionally, the artery 25 can be made of transparent soft silicone. Specifically, the whole body vascular intervention training model of Purin Medical Technology can be selected. Optionally, the high potassium liquid concentration controller can supplement the high potassium liquid concentration in the artery 25. Specifically, the high potassium liquid concentration controller can be a pulsating pump, which uses the pulsating pump to supplement the high potassium liquid outside the simulation dummy into the artery 25 to ensure sufficient supply of high potassium liquid.

[0046] Specifically, learners can use a needle to poke into the artery 25, extract the high potassium liquid in the artery 25, and then test the concentration of the high potassium liquid to diagnose whether hyperkalemia exists based on the concentration of the high potassium liquid, so as to further identify the manifestation characteristics of malignant hyperthermia.

[0047] In addition, since the artery 25 can be made of transparent soft silicone, the insertion site of the artery 25 can heal automatically, so that the needle insertion and withdrawal actions can be repeated, ensuring the continuation of teaching activities.

[0048] The tremor simulator 26 is disposed in the simulation mannequin 10. The tremor simulator 26 is used to simulate muscle tremor symptoms. The tremor simulator 26 is electrically connected to the control module 30. Specifically, the tremor simulator 26 is installed at common tremor parts of the simulation mannequin 10, such as hands, head, and trunk. Optionally, the tremor simulator 26 can be a vibrator, and the vibration emitted by the vibrator is used to simulate muscle tremor symptoms.

[0049] The implementation principle of a malignant hyperthermia clinical skill training simulation dummy in the embodiment of the present application is as follows: during the skill training teaching, the learner introduces a certain amount of anesthetic into the throat of the simulation human model 10, and after the gas inhalation detector 24 detects, the control module 30 controls the heart simulator 20, the stiffness simulator 21, the thermometer 22, the tremor simulator 26, and the carbon dioxide exhalation simulator 23 to respectively show corresponding symptoms. Then the learner can check and judge these symptoms respectively. For example, when judging whether the symptoms shown by the heart simulator 20 are arrhythmia symptoms, the learner can check and judge the heart part in combination with the electrocardiogram. The symptoms shown by the heart simulator 20 can also be normal heart rhythm symptoms. It can be examined whether the learner can accurately judge whether the patient has arrhythmia symptoms based on the electrocardiogram. The inspection actions for other symptoms are the same as the standard actions for the actual inspection of the patient. In this process, the control module 30 can control several of the simulators in the simulator to show corresponding symptoms, and other simulators do not show symptoms, so that the learner can accurately diagnose the malignant hyperthermia disease based on only certain symptoms and the CGS scale.

[0050] This application can comprehensively and realistically simulate various clinical symptoms of malignant hyperthermia, improve the practicality and authenticity of medical teaching, and enable learners to deeply understand and master the treatment methods of malignant hyperthermia in actual operations.

[0051] Example 2 The difference between the embodiment of the present application and embodiment 1 is that the teaching of the case of different manifestations of malignant hyperthermia symptoms when the patient suffers from spinal cord injury resulting in temperature regulation dysfunction is added.

[0052] Typical symptoms of malignant hyperthermia are: high fever: mainly manifested by an abnormally rapid rise in core body temperature after anesthesia, which can usually exceed 40°C and sometimes exceed 43°C; muscle rigidity: usually the earliest symptom, usually masseter spasm first, and skeletal muscle rigidity throughout the body may occur. Malignant hyperthermia is accompanied by tachycardia and shortness of breath.

[0053] Therefore, when doctors judge whether a patient has malignant hyperthermia, they often use high fever as an important criterion. If the patient does not show symptoms of high fever, doctors generally will not diagnose the patient as having malignant hyperthermia. However, there is a special case in which the patient suffered from spinal cord injury, which caused temperature regulation dysfunction. In the early stage of anesthesia, the temperature regulation dysfunction masked the symptoms of high fever, which led to the doctor's misjudgment. The patient was not classified as a malignant hyperthermia patient in time, resulting in the measures taken not being timely, which ultimately led to a fatal outcome.

[0054] Therefore, the simulation dummy of this embodiment can simulate the performance of this special case to help learners learn and master the diagnostic skills of this case to better protect the patient's life safety.

[0055] Reference Figure 2 The simulated dummy also includes a spine simulator 40 arranged on the back of the simulated human model 10 and temperature sensors 41 arranged at the limbs of the simulated human model 10. The spine simulator 40 and the temperature sensor 41 are both electrically connected to the control module 30, and the spine simulator 40 is connected to an evoked potential detector 42.

[0056] The control module 30 can control whether the spinal simulator 40 sends a specific signal. Specifically, the specific signal is a signal that triggers the evoked potential detector 42 to display the potential diagram of the spinal injury. Whether to send a specific signal can be selectively operated by personnel. For example, when the signal is turned off, when the control module 30 receives the temperature signal transmitted by the temperature sensor 41, the control module 30 controls the spinal simulator 40 not to send a specific signal; for example, when the signal is turned on, when the control module 30 receives the temperature signal transmitted by the temperature sensor 41, the control module 30 controls the spinal simulator 40 to send a specific signal.

[0057] A low temperature environment is applied to the limbs of the simulated human model 10. Specifically, the low temperature environment is an environment below 10°C. The low temperature environment can be applied to the limbs of the simulated human model 10 by a temperature regulating sleeve, which can be mounted on the limbs of the simulated human model 10, and the temperature in the temperature regulating sleeve can be adjusted. Specifically, a temperature controller can be installed in the temperature regulating sleeve, and the temperature in the temperature regulating sleeve can be adjusted by the temperature controller.

[0058] When the on signal is selected, the temperature sensor 41 obtains temperature information and sends a signal to the control module 30, the control module 30 sends a signal to the spine simulator 40, and the spine simulator 40 sends a specific signal to the evoked potential detector 42, so that the evoked potential detector 42 can display the potential diagram of the spinal injury. If the off signal is selected, the evoked potential detector 42 displays the normal potential diagram of the spine.

[0059] Since this special case has a body temperature regulation dysfunction, before anesthesia, the limbs of the simulated human model 10 are stimulated by a low-temperature environment, and then the spine simulator 40 is tested using an evoked potential detector 42. Then, based on the potential diagram of the evoked potential detector 42, it is determined whether there are symptoms of body temperature regulation dysfunction caused by spinal cord injury.

[0060] Specifically, the spine simulator 40 does not need to simulate the characteristics of the human spine. It can be a signal transmitter that only needs to transmit the low temperature information of the limbs to the evoked potential detector 42. The evoked potential detector 42 has pre-stored potential maps of the symptoms of temperature regulation dysfunction caused by spinal cord injury. When the evoked potential detector 42 receives the low temperature information transmitted by the signal transmitter, the evoked potential detector 42 displays the corresponding potential map for learners to observe and judge.

[0061] That is, the teaching examines whether the learners first perform a spinal injury examination before anesthetizing the patient, and whether they can determine whether there is a spinal injury based on the potential diagram. If the patient is diagnosed with symptoms of temperature regulation dysfunction caused by spinal cord injury, the patient is very likely not to show a symptom of high fever during the subsequent anesthesia process. At this time, it is necessary to diagnose malignant hyperthermia in a timely manner by diagnosing other symptoms.

[0062] Reference Figure 2 and Figure 3 At the same time, the thermometer 22 is electrically connected to the spine simulator 40; when the control module 30 controls the spine simulator 40 to send a specific signal, the control module 30 sends a low temperature signal to the thermometer 22 to make the thermometer 22 simulate the normal body temperature characteristics.

[0063] Specifically, when the simulation dummy simulates the symptoms of temperature regulation dysfunction caused by spinal cord injury, the thermometer 22 in the subsequent anesthesia will correspondingly simulate the symptoms of human hypothermia, so as to more accurately feedback the real situation and improve the teaching effect.

[0064] The simulation dummy of the present application scheme can simulate the symptom scenario of a patient having temperature regulation dysfunction caused by spinal cord injury. For patients with this type of special symptoms, it helps learners to learn and understand the symptoms, thereby facilitating the identification and diagnosis of the special symptoms in subsequent clinical processes, so that treatment measures can be taken in time to ensure the patient's life safety.

[0065] Example 3 The difference between the present embodiment and the embodiment 1 is that a treatment teaching simulation of malignant hyperthermia is added. Figure 4 In this embodiment, the simulation dummy also includes a vein 50 arranged on the hand of the simulation human body model 10, and the vein 50 can be used to contain dantrolene sodium liquid. The vein 50 is connected to a dantrolene sodium detector 51, and the dantrolene sodium detector 51 is electrically connected to the control module 30.

[0066] Among them, the dantrolene sodium detector 51 can obtain the dantrolene sodium concentration value in the vein 50, and the control module 30 controls the heart simulator 20, the stiffness simulator 21, the thermometer 22, and the carbon dioxide exhalation simulator 23 to simulate different degrees of symptom manifestation according to the dantrolene sodium concentration value.

[0067] Optionally, the dantrolene sodium detector 51 can be a liquid chromatograph-mass spectrometer, which is installed on the outside of the simulated human body model 10. The liquid chromatograph-mass spectrometer is connected to a pulsating pump, and the pulsating pump is used to draw the liquid in the vein 50 into the liquid chromatograph-mass spectrometer. The liquid chromatograph-mass spectrometer detects the concentration of dantrolene sodium in the liquid. The control module 30 gradually reduces the degree of symptom simulation of the simulator according to the concentration of dantrolene sodium until the symptoms simulated by the simulator completely disappear.

[0068] This teaching examines whether the learners can provide timely infusion to patients when they are diagnosed with malignant hyperthermia, whether they have adopted effective measures to treat the symptoms of malignant hyperthermia, and whether they need to continue infusing dantrolene sodium liquid according to the manifestation of symptoms during the treatment process.

[0069] At the same time, the armpits, chest and groin of the simulated human model 10 are provided with cooling sensors 52, and the cooling sensors 52 are electrically connected to the control module 30. The cooling sensors 52 can obtain the temperature values ​​of the armpits, chest and groin, and the control module 30 controls the thermometer 22 to simulate normal body temperature symptoms after a preset time according to the temperature values.

[0070] Specifically, the preset time can be set according to the body temperature drop time of a normal malignant hyperthermia patient after a cooling operation.

[0071] This teaching examines whether the learners take effective cooling measures to help them master the operation of cooling patients.

[0072] In addition to enabling learners to diagnose malignant hyperthermia, the embodiments of the present application can also provide treatment teaching for malignant hyperthermia, thereby enhancing their practical operation ability and clinical response experience.

[0073] The present application also discloses a method for using a malignant hyperthermia clinical skill training simulation dummy, comprising the following steps: S1. Pass a gas containing a certain amount of anesthetic into the throat of the simulated human body model 10, and the gas inhalation detector 24 inhales the gas and detects the anesthetic content in the gas. When the detected anesthetic content reaches a certain value, the control module 30 controls the heart simulator 20, the stiffness simulator 21, the thermometer 22, and the carbon dioxide exhalation simulator 23 to respectively show corresponding symptoms.

[0074] In addition, an artery 25 and a tremor simulator 26 may be installed in the simulation human body model 10, and the control module 30 controls the artery 25 and the tremor simulator 26 to show corresponding symptoms.

[0075] S2. The learner uses appropriate instruments or actions to check the symptoms exhibited by the simulated dummy.

[0076] Specifically, symptoms of arrhythmia can be checked with an electrocardiogram; symptoms of muscle stiffness and muscle tremor can be checked by palpation; symptoms of elevated body temperature can be checked with a thermometer; symptoms of increased carbon dioxide partial pressure can be checked using a conductivity detector; and symptoms of hyperkalemia can be checked through blood sample testing.

[0077] S3. The learner diagnoses whether the simulated dummy suffers from malignant hyperthermia based on the symptoms detected.

[0078] Specifically, students will diagnose whether it is malignant hyperthermia based on the symptoms found during the examination and the CGS scale.

[0079] S4. The instructor shall judge and guide the learners on the order of symptom examination, examination actions and diagnostic results.

[0080] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
