Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the protection scope of the present invention.

[0021] It should be understood that when used in the specification and appended claims of the present invention, the term "comprising" indicates the presence of the described features, wholes, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations. It should also be understood that the term " / and" as used in the specification and appended claims of the present invention refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0022] In addition, in the description of the specification and appended claims of the present invention, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0023] References to "one embodiment" or "some embodiments" etc. described in the specification of the present invention mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present invention. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized.

[0024] It should be understood that the magnitudes of the sequence numbers of the steps in the following embodiments do not mean the order of execution is prior or posterior. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0025] In order to illustrate the technical solution of the present invention, the following specific embodiments are used for illustration.

[0026] It should be understood that currently, during the transportation of critically ill patients in emergency situations, medical staff accompanying in ambulances or transport aircrafts need to take corresponding first-aid measures in a timely manner according to the actual changes in the patient's body condition to ensure the patient's life safety. In the traditional transportation system, the first-aid means for patients rely more on the personal experience of medical staff. However, in actual applications, in situations such as natural disasters, wars, or major emergencies with a large number of casualties, there may be a shortage of rescue resources or medical staff. The traditional transportation system is difficult to meet the transportation needs in different scenarios and cannot transport relevant personnel in a timely and safe manner, resulting in low transportation efficiency and safety. With the increasing maturity of unmanned driving and drone technologies, providing a transportation system to perform safe transportation without human escort is beneficial to meeting the transportation needs in special scenarios such as mass injuries, and can meet the transportation tasks in both scenarios with human escort and without human escort, improving the transportation efficiency and safety of the wounded and sick.

[0027] At the same time, since the treatment of the wounded and sick in the traditional transportation process mainly relies on manual operations, it is difficult to effectively monitor the vital signs of the wounded and sick during transportation, and corresponding first-aid measures cannot be automatically implemented according to the injury conditions. The first-aid measures may be lagged, or the situation of improper implementation of the first-aid measures may easily occur. For example, when a wounded and sick person has cardiac arrest or respiratory failure, first-aid personnel often need to judge based on experience and manually perform chest compressions, which has a certain lag and uncertainty.

[0028] In addition, due to the unstable operation of vehicles or aircraft during the transportation process, the postures of patients or the injured are prone to change, and the relative positions between relevant medical devices and the injured are unstable. It is often difficult to ensure that relevant devices (such as medical first-aid devices like vital sign monitoring devices and pressing devices) are always in the appropriate positions, thereby affecting the monitoring accuracy of vital sign data and the first-aid effect (such as the effect of external chest compressions).

[0029] In view of the above problems, in the embodiments of the present application, a transportation system, a control device, a device, a medium, and a program product are provided, which can provide an intelligent transportation system and its integrated device control solution, improve the automation and intelligence level of the transportation system. When rescue resources are scarce or personnel are insufficient, the transportation system can still autonomously and efficiently perform first-aid operations, meeting the transportation needs of the injured in various scenarios and improving the personnel transportation efficiency and transportation safety.

[0030] Among them, the transportation system includes a negative pressure fixing device, a chest pressing device, and a monitoring device, as well as a control device and a transportation device provided with an injured person placement space; the negative pressure fixing device is used to fix the position of the injured person, fix the chest pressing device to the chest position of the injured person, and fix the monitoring device at the corresponding monitoring position of the injured person. The control device is configured to: during the transportation of the target injured person by the transportation device, control the monitoring device to monitor the vital sign data of the target injured person, where the vital sign data includes the displacement data of chest breathing activities and the carotid blood flow velocity of the target injured person; evaluate the physical state of the target injured person according to the displacement data of chest breathing activities and the carotid blood flow velocity, and when the physical state is an abnormal physical state, query the first-aid measures corresponding to the abnormal physical state; when the first-aid measure indicates performing external chest compressions, control the chest pressing device located at the chest position of the target injured person to execute the external chest compression process, and adjust the pressing depth of the chest pressing device according to the carotid blood flow velocity. On the one hand, during the transportation process, the displacement data of chest breathing activities and carotid blood flow data of the target injured person are monitored by the monitoring device, improving the continuity and accuracy of vital sign data collection. Based on this, the breathing condition and blood circulation condition of the injured person can be accurately evaluated. When it is necessary to assist in judging the need to perform first-aid measures such as external chest compressions, the relevant device can be timely controlled to execute the external chest compression process, ensuring that the first-aid operation is more accurate and timely and guaranteeing the safety of relevant personnel; on the other hand, the transportation system provides an integrated vital sign monitoring and device control solution, reducing human intervention during transportation and first-aid processes, improving the automation and intelligence level of the transportation system. When rescue resources are scarce or personnel are insufficient, the transportation system can still autonomously and efficiently perform first-aid operations, meeting the transportation needs of the injured in various scenarios and improving the personnel transportation efficiency and transportation safety.

[0031] The transportation system provided by the embodiments of the present invention, such as Figure 1As shown in the figure, the transportation system includes a negative pressure fixing device, a chest compression device, a monitoring device, as well as a control device and a transportation device provided with a casualty placement space. Among them, the negative pressure fixing device and the chest compression device communicate with the detection and monitoring device through a network (such as a 5G network) or a cable.

[0032] Among them, the negative pressure fixing device is used to fix the position of the casualty, avoiding physical injuries caused by the unstable position of the casualty during transportation due to sudden situations. In particular, it can reduce secondary injuries caused by unstable positions for casualties with spinal injuries and fractures. In addition, the negative pressure fixing device is also used to fix the chest compression device to the chest position of the casualty, and fix the monitoring device at the corresponding monitoring position of the casualty, avoiding the unstable relative position between the device and the casualty during transportation, which may affect the monitoring accuracy of physical sign data and the first aid effect.

[0033] Specifically, the control device is configured to: during the transportation of the target casualty by the transportation device, the control device controls the monitoring device fixed on the target casualty to monitor the physical condition of the target casualty in real time, that is, to monitor the physical sign data of the target casualty in real time. For example, it monitors the displacement data of the chest breathing activity and the carotid blood flow velocity of the target casualty. That is, the physical sign data at least includes the displacement data of the chest breathing activity of the target casualty and the carotid blood flow velocity. The control device evaluates the physical state of the target casualty according to the displacement data of the chest breathing activity and the carotid blood flow velocity, and when the physical state is an abnormal physical state, it queries the first aid measures corresponding to the abnormal physical state; when the first aid measure indicates external chest compression, it controls the chest compression device located at the chest position of the target casualty to execute the external chest compression process, and adjusts the compression depth of the chest compression device according to the carotid blood flow velocity.

[0034] In the transportation system of this embodiment, during transportation, the monitoring device monitors the displacement data of the chest breathing activity and the carotid blood data of the target casualty, improving the continuity and accuracy of physical sign data collection. Based on this, the breathing condition and blood circulation condition of the casualty can be accurately evaluated. When it is necessary to assist in judging the need to implement first aid measures such as external chest compression, the relevant device can be timely controlled to execute the external chest compression process, ensuring that the first aid operation is more accurate and timely, and guaranteeing the safety of relevant personnel. The transportation system provides an integrated physical sign monitoring and device control solution, reducing human intervention during transportation and first aid, improving the automation and intelligent level of the transportation system. When rescue resources are scarce or personnel are insufficient, the transportation system can still independently and efficiently implement first aid operations, meeting the transportation needs of casualties in various scenarios, and improving the personnel transportation efficiency and transportation safety.

[0035] Among them, the monitoring device can be an electronic device installed inside a transportation device (such as a vehicle or an aircraft). For example, the monitoring device can be various personal computers, laptops, smartphones, tablets, and portable wearable devices installed inside the transportation device. The monitoring device can also be installed on a server outside the transportation equipment, such as a cloud server, which can be implemented by an independent server or a server cluster composed of multiple servers.

[0036] To illustrate the structure and function of the transfer system in this embodiment in detail, the following will Figures 2 to 7 describe the functions and implementation principles of each device in the transfer system.

[0037] In one embodiment, as Figure 2 shown, the control device in the transfer system is configured to perform the following steps: S10: During the process of transferring the target injured patient through the transportation device, control the monitoring device to monitor the physical sign data of the target injured patient. The physical sign data includes the displacement data of the chest breathing activity and the carotid blood flow velocity of the target injured patient.

[0038] Among them, the transfer system provided in this embodiment includes a negative pressure fixation device, a chest compression device, and a monitoring device, as well as a transportation device provided with an injured patient placement space. Among them, the negative pressure fixation device is a mobile portable fixation device, which is used to fix the position of the injured patient to avoid physical injuries caused by the unstable position of the injured patient due to sudden situations during the transfer process. In addition, the negative pressure fixation device is also used to fix the chest compression device to the chest position of the injured patient, and to fix the monitoring device to the corresponding monitoring position of the injured patient, so as to avoid the unstable relative position between the device and the injured patient during the transfer process, which may affect the monitoring accuracy of the physical sign data and the first aid effect.

[0039] In the actual application process, relevant personnel (such as medical staff or the injured patient himself) transfer the target injured patient to the injured patient placement space of the transportation device, and fix the negative pressure fixation device at the corresponding position of the target injured patient, so that the position of the target injured patient in the injured patient placement space is fixed, and the transportation device runs to transfer the target injured patient to the designated location.

[0040] Among them, during the process of transferring the target injured patient through the transportation device, the control device controls the monitoring device to monitor the physical condition of the target injured patient in real time, that is, to monitor the physical sign data of the target injured patient in real time. For example, monitor the displacement data of the chest breathing activity and the carotid blood flow velocity of the target injured patient. That is, the physical sign data at least includes the displacement data of the chest breathing activity of the target injured patient and the carotid blood flow velocity, so as to assist in judging whether relevant first aid operations can be performed on the target injured patient.

[0041] S20: Evaluate the physical state of the target injured person according to the displacement data of chest breathing activity and the carotid blood flow velocity.

[0042] During the process of monitoring the physical sign data of the target injured person, that is, during the process of collecting the displacement data of the chest breathing activity of the target injured person and the carotid blood flow velocity, the control device can evaluate the physical state of the target injured person according to the displacement data of the chest breathing activity and the carotid blood flow velocity.

[0043] Among them, the control device can determine the chest movement amplitude and breathing frequency of the target injured person according to the displacement data of the chest breathing activity. The chest movement amplitude is the undulation amplitude of the chest during human breathing, that is, the displacement amount of the up and down movement of the chest during human breathing activity, which is determined by the difference in displacement values measured during exhalation and inhalation of the target injured person. One undulation of the human chest is one breath, that is, one inhalation and one exhalation is one breath, and the breathing frequency is the number of breaths per minute. By the displacement data of the chest breathing activity, determine the time required for one breath, that is, every time the displacement number of the chest is monitored to increase and then decrease is one breath, and determine the time required for this exhalation, and then predict the number of breaths per minute, that is, obtain the breathing frequency.

[0044] After obtaining the chest movement amplitude and breathing frequency of the target injured person, the control device can evaluate the physical state of the target injured person according to the carotid blood flow velocity, chest movement amplitude and breathing frequency. The carotid blood flow velocity, chest movement amplitude and breathing frequency of the living body can characterize the changes in the vital signs of the target injured person. Through the carotid blood flow velocity, chest movement amplitude and breathing frequency, it can be quickly judged whether there is a life danger in the living body, so as to quickly assist in judging whether to execute the corresponding first aid measures.

[0045] For example, when the monitored carotid blood flow velocity (or blood flow volume) of the target injured person is 0, that is, no carotid blood flow is detected and the heart has stopped beating, and the monitored chest movement amplitude is 0 and the breathing frequency is 0, it is determined that the physical state of the target injured person is a state of cardiac and respiratory arrest, then first aid measures such as cardiopulmonary resuscitation can be taken for the target injured person to promptly restore the heartbeat and breathing of the target injured person.

[0046] In other embodiments, when any two of the screening conditions corresponding to the cardiorespiratory arrest state are met by the carotid blood flow velocity, the amplitude of thoracic movement, and the respiratory rate, it is determined that the physical state of the target casualty is the cardiorespiratory arrest state. The screening conditions corresponding to the cardiorespiratory arrest state include: the respiratory rate is less than a preset frequency, the amplitude of thoracic movement is less than a preset range of motion, and the carotid blood flow velocity is less than a preset flow velocity. By judging two screening conditions corresponding to the cardiorespiratory arrest state, the possibility of misjudgment can be reduced, the judgment accuracy can be improved, and the safety of the casualty can be ensured. Among them, the preset frequency can be 0 or a frequency value close to 0 (such as 1 time / min); the preset range of motion can be 0 or a value close to 0 (such as 0.1 cm); the preset flow velocity can be 0 or a flow velocity value close to 0 (such as 1 cm / s).

[0047] S30: When the physical state is an abnormal physical state, query the first aid measures corresponding to the abnormal physical state.

[0048] Among them, the control device pre-stores the first aid measures corresponding to different physical states. After evaluating the physical state of the target casualty, the control device determines whether the physical state is an abnormal physical state; when it is determined that the physical state is an abnormal physical state, query the first aid measures corresponding to the abnormal physical state, so as to control the relevant equipment to execute the corresponding first aid process according to the first aid measures.

[0049] Among them, the abnormal physical state can also include states such as cardiorespiratory arrest state, shock state, ventricular fibrillation state, hypoxia state, etc., as well as abnormal respiratory states such as too fast exhalation and too slow exhalation; it also includes abnormal blood pressure states such as too low blood pressure and too high blood pressure, abnormal blood flow states such as too low blood flow, too high blood flow or blood flow stop, and abnormal blood oxygen states such as low blood oxygen saturation.

[0050] In one embodiment, a pre-trained first neural network model can be used to perform motion analysis on the displacement data of the chest breathing activity of the target casualty, so as to analyze the amplitude of thoracic movement and the respiratory rate of the target casualty, and accordingly predict the respiratory state of the target casualty, and judge whether the respiratory state of the target casualty is an abnormal respiratory state such as too fast breathing, asymmetric breathing, or respiratory arrest. Then, a pre-trained second neural network model can be used to identify the blood flow state of the carotid blood flow velocity of the collected target casualty, obtain the blood flow state of the target casualty, so as to determine whether the blood flow state of the target casualty is an abnormal blood flow state. When the respiratory state of the target casualty is an abnormal respiratory state, or its blood flow state is an abnormal blood flow state, then the physical state of the target casualty is evaluated as an abnormal physical state, so as to determine the corresponding first aid measures according to the abnormal physical state (such as abnormal respiratory state, abnormal blood flow state).

[0051] Among them, the first neural network model can be a three-dimensional convolutional neural network model; the second neural network model can be a recurrent neural network model.

[0052] S40: When the first aid measure indicates performing external chest compressions, control the chest compression device located at the chest position of the target injured person to execute the external chest compression process, and adjust the compression depth of the chest compression device according to the carotid blood flow velocity.

[0053] When the first aid measure indicates performing external chest compressions, the control device can control the chest compression device located at the chest position of the target injured person to execute the external chest compression process, so as to promptly restore the heartbeat and breathing of the target injured person.

[0054] For example, the monitoring device can include a displacement sensor for monitoring the displacement amount of the thoracic respiratory movement, and an ultrasonic blood flow sensor for monitoring the carotid blood flow velocity and blood flow volume. When the heart of the target injured person beats normally, the ultrasonic blood flow sensor will monitor the blood flow through the carotid artery, and in the process of continuous data collection, basic parameters such as the blood flow volume and blood flow velocity of the injured person's carotid artery will be formed. When the heart of the target injured person stops beating, the ultrasonic blood flow sensor cannot monitor the blood flow through, that is, it monitors that the blood flow volume and blood flow velocity of the injured person's carotid artery are 0. Then, the control device combines the displacement data collected by the displacement sensor located at the chest to judge whether an emergency situation of cardiac and respiratory arrest occurs to the target injured person (that is, the physical state of the target injured person is a state of cardiac and respiratory arrest), and when it is determined that an emergency situation of cardiac and respiratory arrest occurs, query the first aid measures corresponding to the cardiac and respiratory arrest to start the chest compression device to execute the external chest compression process.

[0055] Among them, in the process of controlling the chest compression device to execute the external chest compression process, the compression depth of the chest compression device can be adjusted according to the carotid blood flow velocity to improve the compression effect and reduce the human damage caused by excessive compression. In the process of executing the external chest compression process, when the carotid blood flow velocity increases, the compression depth of the chest compression device is reduced; when the carotid blood flow velocity decreases, the compression depth of the chest compression device is increased until the monitored carotid blood flow velocity reaches the calibrated velocity value (and the thoracic movement amplitude reaches the calibrated value), and then control the chest compression device to stop compression.

[0056] In the transfer system of this embodiment, during the transfer process, the monitoring device monitors the physical sign data of the target injured or sick person, such as chest breathing activity displacement data and carotid artery blood flow data, which can improve the continuity and accuracy of physical sign data collection, and can accurately evaluate the breathing condition and blood circulation condition of the injured or sick person. When assisting in judging that first aid measures such as external chest compressions need to be implemented, the relevant device can be controlled in a timely manner to execute the external chest compression process, ensuring that the first aid operation is more accurate and timely, and guaranteeing the safety of relevant personnel. At the same time, the transfer system provides an integrated physical sign monitoring and medical device control solution for the injured or sick person, reducing human intervention during the transfer and first aid processes, improving the automation and intelligent level of the transfer system. When rescue resources are scarce or there are insufficient personnel, the transfer system can still independently and efficiently implement first aid operations, reducing the dependence on medical staff, meeting the transfer needs of the injured or sick person in various scenarios, and improving the personnel transfer efficiency and transfer safety.

[0057] In one embodiment, after querying the first aid measures corresponding to the abnormal physical state, the control device can send the carotid artery blood flow velocity, chest movement amplitude, breathing frequency, and the first aid measures taken to the terminal device of the medical staff to request the medical staff to confirm whether to execute the first aid measures according to the sent data; after receiving the confirmation instruction from the medical staff, the chest compression device located at the chest position of the target injured or sick person is controlled to execute the external chest compression process, and the compression depth of the chest compression device is adjusted according to the carotid artery blood flow velocity. By having the relevant first aid measures confirmed by professionals before execution, it can avoid physical injuries caused by incorrect execution of first aid by machine recognition, improve the accuracy of the external chest compression process execution, and enhance the safety of the injured or sick person.

[0058] If no confirmation instruction from the medical staff or cancellation instruction of the first aid measure is received within a preset time period (such as 2 minutes), the control device directly controls the chest compression device located at the chest position of the target injured or sick person to execute the external chest compression process, and adjusts the compression depth of the chest compression device according to the carotid artery blood flow velocity. This solution can avoid first aid delays caused by signal interruption or personnel absence, perform first aid for the injured or sick person in a timely manner, and improve the life safety of the injured or sick person.

[0059] In one embodiment, as Figure 3 shown, the monitoring device of the transfer system includes a first flexible sensor 21 and a second flexible sensor 22. The first flexible sensor 21 can be a displacement sensor (such as a three - dimensional displacement sensor) for monitoring the displacement change of the chest activity of the injured or sick person; the second flexible sensor 22 is a blood flow sensor made of flexible material for monitoring the blood flow volume and blood flow velocity of the carotid artery of the injured or sick person. The second flexible sensor 22 can be an ultrasonic blood flow sensor made of flexible material for measuring the carotid artery blood flow volume and carotid artery blood flow velocity.

[0060] In this solution, the flexible sensor can conform to the curved surface changes of the chest and neck, fit the target area after fixation, effectively reduce displacement and interference, thereby improving the acquisition accuracy of chest breathing movement displacement data and carotid artery blood flow data, and providing a reliable basis for subsequent judgment of the respiratory and circulatory status.

[0061] The negative pressure fixing device includes a flexible fixing device 1, a negative pressure device (not shown), and a communication device (which can be a 5G communication device). The negative pressure device is arranged inside the flexible fixing device. After the negative pressure device operates, the flexible fixing device surrounds and fixes the torso and neck of the injured patient. The first flexible sensor 21 and the second flexible sensor 22 are respectively electrically connected to the communication device. The first flexible sensor 21 and the second flexible sensor 22 are respectively arranged at corresponding positions of the flexible fixing device 1.

[0062] The communication device is used to control the start and stop of the first flexible sensor 21 and the second flexible sensor 22 in response to the control signal of the control device, and send the data collected by the first flexible sensor 21 and the second flexible sensor 22 to the control device. In this solution, by controlling the flexible fixing device 1 to surround and fit the torso and neck of the target injured patient through the negative pressure fixing device, not only can the position of the injured patient be quickly and firmly fixed, but also the sensor and the chest compression device can be accurately positioned to the key areas of the chest and neck of the injured patient, improving the positioning accuracy and functional implementation reliability of the device.

[0063] In one embodiment, as Figure 3 shown, the flexible fixing device includes a first part 11 and a second part 12. The first part 11 is used to cover and fix the torso of the injured patient; the second part 12 is used to cover and fix the neck of the injured patient. The cavities of the first part 11 and the second part 12 are communicated. The first part 11 of the flexible fixing device 1 is also provided with an exhaust structure 51. When the flexible fixing device 1 performs negative pressure fixation on the injured patient, the negative pressure transfer station performs gas pumping and discharging through the exhaust structure 51, so that the first part 11 of the flexible fixing device 1 surrounds and fixes the torso of the injured patient when the negative pressure device operates, and the second part 12 of the flexible fixing device 1 surrounds and fixes the neck of the injured patient.

[0064] In other embodiments, the cavities of the first part 11 and the second part 12 are not communicated, that is, the first part 11 and the second part 12 can be two independent parts. Negative pressure devices and exhaust structures 51 are arranged in the cavities of the first part 11 and the second part 12 respectively, so that the first part 11 of the flexible fixing device 1 surrounds and fixes the torso of the injured patient after the negative pressure device operates, and the second part 12 of the flexible fixing device 1 surrounds and fixes the neck of the injured patient after the negative pressure device operates, improving the fixing effect of the flexible fixing device 1.

[0065] Among them, the negative pressure device includes a vacuum pump (not shown), a power supply for the vacuum pump (i.e., the first power supply) 41, and a negative pressure pipeline (not shown). The negative pressure pipeline is arranged in the cavity of at least one of the first part 11 and the second part 12. When it is necessary to fix the wounded or sick personnel by negative pressure or release the wounded or sick personnel with the flexible fixing device 1, the exhaust structure 51 is controlled to open, and the negative pressure device is controlled to operate, so that the flexible fixing device 1 performs other pumping and discharging, so that the flexible fixing device 1 can surround and fix the corresponding body part of the wounded or sick personnel or release the wounded or sick personnel. Among them, the negative pressure pipeline can be a pipeline made of medical silicone, so that the negative pressure pipeline has the characteristics of flexibility, pressure resistance and high-temperature sterilization.

[0066] In one embodiment, the flexible fixing device 1 may further include a sealing structure, that is, the first part 11 and the second part 12 are also provided with a sealing structure (such as a gasket, a sealing ring) for placing other devices. For example, the first flexible sensor 21 is installed at the corresponding position of the first part 11 through the sealing structure, such as at the position corresponding to the chest of the wounded or sick personnel in the first part 11; the second flexible sensor 22 is installed at the corresponding position of the second part 12 through the sealing structure, such as at the position corresponding to the artery of the neck of the wounded or sick personnel in the second part 12. To improve the accuracy of the chest breathing movement displacement data, the number of the first flexible sensors 21 can be 4; to improve the accuracy of the blood flow data (blood flow volume and blood flow velocity), the number of the second flexible sensors 22 can be 2, as Figure 3 shown. Among them, the sealing structure can be a gasket or a sealing ring made of silicone or fluororubber to ensure airtightness.

[0067] In one embodiment, the flexible fixing device 1 is made of silicone, and the cavity of the flexible fixing device 1 is filled with polyvinyl alcohol foam. That is, as Figure 4 shown, the flexible fixing device consists of an outer silicone layer, a polyvinyl alcohol foam layer and an inner silicone layer, and the negative pressure device is arranged in the polyvinyl alcohol foam layer. The inner silicone layer is the silicone layer in contact with the skin of the wounded or sick personnel, and a sealing structure is provided on the side of this silicone layer in contact with the skin of the wounded or sick personnel to place the first flexible sensor 21 and the second flexible sensor 22. In addition, a sealing interface is provided at the edge of the outer silicone layer for placing the power supply of the negative pressure device to ensure airtightness.

[0068] In one embodiment, as Figure 3As shown in the figure, the chest compression device is installed on the flexible fixing device 1 of the negative pressure fixing device through a fixing strap 7 that can be telescopically adjusted in position. The chest compression device includes a power source (i.e., the second power source) 61, a pneumatic pressing device 62, a pressing pad 63 for the sternum, a pneumatic pressing spring device 64 that can adjust the pressing depth, and a communication device. Among them, the pneumatic pressing device 62 is located in the fixing strap 7, and the pneumatic pressing device 62 provides power to compress or release the pneumatic pressing spring device 64 to achieve external chest compression of the injured patient. The communication device is used to start and stop the chest compression device in response to the control signal of the control device and send the operation data of the chest compression device to the control device.

[0069] Among them, as Figure 3 shown, the chest compression device may further include a buckle strap 65, and the buckle strap 65 can be connected to the patient placement platform in the transfer stretcher or transportation device to fix the negative pressure fixing device with the chest compression device fixed thereon to the transfer stretcher or the patient placement platform and achieve the position fixation of the injured patient.

[0070] Among them, the negative pressure fixing device may further include a start switch (not shown), and the start switch is used to start and stop the negative pressure fixing device. Before or during the transfer of the injured patient, the medical staff or the injured patient himself wraps the flexible fixing device around the trunk and neck of the injured patient, so that various sensors and the chest compression device are located at the corresponding positions of the injured patient, and then the exhaust device is opened, the power supply of the negative pressure device is started, and the negative pressure device performs mechanical air extraction to form negative pressure fixation. After that, the medical staff or the injured patient opens the start switch so that the start switch sends a start signal to the control device to start the monitoring process.

[0071] In an embodiment, as Figure 5 shown, in step S10, that is, the control device controls the monitoring device to monitor the displacement data of the chest breathing activity of the target injured patient and the carotid blood flow velocity of the target injured patient, which is configured to perform the following steps: S11: Receive the start signal of the negative pressure fixing device.

[0072] Among them, the negative pressure fixing device may further include a start switch, and the start switch is used to start and stop the negative pressure fixing device. After the relevant personnel (medical staff, injured patient) surround and fix the flexible fixing device on the injured patient, so that the first flexible sensor and the second flexible sensor are respectively fixed on the chest and neck of the target injured patient, and the chest compression device is located at the chest compression position of the target injured patient, the start switch can be opened to send the start signal of the negative pressure fixing device to the control device. The control device receives the start signal of the negative pressure fixing device.

[0073] That is, the start signal is used to indicate that the flexible fixing device is wound around and fixed to the torso and neck of the target injured patient, and indicates that the first flexible sensor and the second flexible sensor are respectively fixed to the chest and neck of the target injured patient, and indicates that the chest compression device is located at the chest compression position of the target injured patient.

[0074] S12: Control the first flexible sensor to collect displacement data of the chest breathing activity of the target injured patient, and control the second flexible sensor to collect the carotid blood flow velocity of the target injured patient.

[0075] After receiving the start signal of the negative pressure fixing device, the control device can determine that the flexible fixing device is wound around and fixed to the torso and neck of the target injured patient, the first flexible sensor and the second flexible sensor are respectively fixed to the chest and neck of the target injured patient, and the chest compression device is located at the chest compression position of the target injured patient, and then control the first flexible sensor to collect displacement data of the chest breathing activity of the target injured patient, and control the second flexible sensor to collect the carotid blood flow velocity of the target injured patient.

[0076] In this embodiment, the control device receives the start signal of the negative pressure fixing device. The start signal is used to indicate that the flexible fixing device is wound around and fixed to the torso and neck of the target injured patient, and indicates that the first flexible sensor and the second flexible sensor are respectively fixed to the chest and neck of the target injured patient, and indicates that the chest compression device is located at the chest compression position of the target injured patient; control the first flexible sensor to collect displacement data of the chest breathing activity of the target injured patient, and control the second flexible sensor to collect the blood flow data of the carotid artery of the target injured patient. Through the coordinated control of the control device with the negative pressure fixing structure, the flexible sensor and the chest compression device, this solution realizes the automatic positioning and stable fixation of the key areas of the chest and neck of the injured patient, and ensures that the sign acquisition device collects the target sign data with high fitting and high sensitivity, significantly improving the accuracy of the injured patient sign monitoring, the timeliness of the system response and the effectiveness of the subsequent first aid operation. After receiving the start signal, the control device can automatically complete the fixing action and synchronously control the start of the data acquisition process, forming an automated process from device deployment → fixation → start → sign monitoring, improving the device response speed and operation efficiency.

[0077] In one embodiment, the transfer system further includes an electrocardiogram monitor disposed in the casualty placement space; the monitoring device further includes electrocardiogram electrode patches of the electrocardiogram monitor; the negative pressure fixing device is used to fix the electrocardiogram electrode patches to the electrocardiogram monitoring positions of the casualty. The electrocardiogram monitoring positions may include three monitoring positions: the upper left chest, the upper right chest, and the lower left chest (or the lower right chest). The upper left chest monitoring position is at the first intercostal space on the midclavicular line to the left of the sternum; the upper right chest monitoring position is at the first intercostal space on the midclavicular line to the right of the sternum; the lower left chest (or the lower right chest) monitoring position is at the costal margin on the left (or right) midclavicular line. The electrocardiogram monitor is provided with an electrode patch interface, and the electrocardiogram monitor is detachably connected to the electrocardiogram electrode patches through the electrode patch interface.

[0078] Before or during the transfer of the casualty, medical staff or the casualty himself / herself wraps the flexible fixing device around the trunk and neck of the casualty, so that various sensors and the chest compression device are located at the corresponding positions of the casualty. Then, the exhaust device is opened, and the power supply of the negative pressure device is started. After the negative pressure device performs mechanical air extraction to form negative pressure fixation. Then, the medical staff or the casualty opens the start switch, so that the start switch sends a start signal to the control device to start the monitoring process. The start signal is used to indicate that the flexible fixing device is wound and fixed around the trunk and neck of the target casualty, and indicates that the first flexible sensor and the second flexible sensor are respectively fixed to the chest and neck of the target casualty, and indicates that the chest compression device is located at the chest compression position of the target casualty, and indicates that the electrocardiogram electrode patches are fixed to the electrocardiogram monitoring positions of the target casualty.

[0079] After step S11, that is, after the control device receives the start signal of the negative pressure fixing device, the control device controls the first flexible sensor to collect the displacement data of the chest breathing activity of the target casualty, controls the second flexible sensor to collect the carotid blood flow velocity of the target casualty, and controls the electrocardiogram electrode patches to collect the electrical activity data of the heart of the target casualty, so as to obtain the physical sign data of the target casualty, increase the types of sensors to collect different types of physical sign data of the casualty, facilitate subsequent judgment of the physical state of the casualty according to various types, and improve the accuracy of the judgment.

[0080] In other embodiments, the electrocardiogram monitor is further connected with sensors such as a blood pressure sensor and a blood oxygen sensor to collect physical sign data such as the blood pressure and blood oxygen saturation of the target casualty, and monitor the changes of the electrocardiogram, blood pressure, blood oxygen saturation, etc. of the target casualty through the electrocardiogram monitor.

[0081] After transferring the injured and sick to the transportation device, during the transfer process, medical staff or the injured and sick themselves wrap the flexible fixing device around the torso and neck of the injured and sick, so that various sensors and chest compression devices are located at the corresponding positions of the injured and sick. Then, the exhaust device is opened, the power supply of the negative pressure device is started, and the negative pressure device performs mechanical air extraction to form negative pressure fixation. At the same time, the blood pressure sensor and blood oxygen sensor are placed at the corresponding monitoring positions of the target injured and sick. After that, the medical staff or the injured and sick open the start switch, so that the start switch sends a start signal to the control device to start the monitoring process.

[0082] In one embodiment, the physical sign data of the target injured and sick further includes the electroactivity data of the heart of the target injured and sick, such as Figure 6 As shown, in step S30, that is, the control device evaluates the physical state of the target injured and sick according to the displacement data of the chest breathing activity and the carotid blood flow velocity, and is configured to perform the following steps: S31: Determine the electrocardiogram waveform of the target injured and sick according to the electroactivity data of the heart.

[0083] In this embodiment, the physical sign data of the target injured and sick further includes the electroactivity data of the heart of the target injured and sick. After the control device obtains the electroactivity data of the heart of the target injured and sick, it can determine the electrocardiogram waveform of the target injured and sick according to the electroactivity data of its heart.

[0084] S32: Determine the thoracic movement amplitude and breathing frequency of the target injured and sick according to the displacement data of the chest breathing activity.

[0085] Among them, the displacement data of the chest breathing activity of the target injured and sick can be monitored by a three-axis displacement sensor, that is, the monitoring device includes a three-axis displacement sensor, and the displacement data of the chest breathing activity of the target injured and sick is collected through the three-axis displacement sensor, so as to determine the thoracic movement amplitude and breathing frequency of the target injured and sick. The thoracic movement amplitude can include the thoracic movement amplitudes in different directions; the thoracic movement amplitude can also be an amplitude value comprehensively determined according to the displacement values of the thoracic movement in different directions.

[0086] The displacement data of the chest breathing activity of the target injured and sick can be collected according to the three-axis displacement sensor, that is, according to the sensor, the thoracic movement direction and amplitude of the target injured and sick within a certain period of time can be extracted, and the thoracic movement (undulation) state of the breathing activity of the target injured and sick within a certain period of time can be reconstructed, such as Figure 7 As shown. Among them, Figure 7 the Z-axis (vertical axis), X-axis (horizontal axis), Y-axis (axis perpendicular to the horizontal axis and vertical axis) in, respectively represent the displacement value in the vertical direction, the displacement value in the horizontal direction, and the displacement value perpendicular to the vertical and horizontal directions during the thoracic breathing activity collected by the three-axis sensor.

[0087] S33: Evaluate the physical condition of the target casualty according to the electrocardiogram waveform, carotid blood flow velocity, thoracic movement amplitude, and respiratory rate.

[0088] After determining the electrocardiogram waveform, thoracic movement amplitude, and respiratory rate of the target casualty, the control device evaluates the physical condition of the target casualty according to the electrocardiogram waveform, thoracic movement amplitude, and respiratory rate, as well as the collected carotid blood flow velocity, and determines whether the physical condition is an abnormal physical condition. When the physical condition is an abnormal physical condition, query the first aid measures corresponding to the abnormal physical condition in the physical condition of the target casualty, so as to control the relevant equipment to execute the corresponding first aid process according to the first aid measures. For example, when it is determined that the physical condition is an abnormal physical condition, such as a state of cardiac arrest and respiratory arrest, query the first aid measures corresponding to the state of cardiac arrest and respiratory arrest, such as external chest compression operation.

[0089] In other embodiments, the abnormal physical conditions may further include states such as shock state, ventricular fibrillation state, hypoxia state, etc., abnormal respiratory states such as too fast exhalation and too slow exhalation, and abnormal blood pressure states such as too low blood pressure and too high blood pressure, abnormal blood flow states such as too low blood flow, too high blood flow or blood flow stop, and abnormal blood oxygen states such as low blood oxygen saturation. The abnormal physical conditions may further include abnormal limb movement states such as limb twitching, and abnormal expression states such as restlessness, painful expression, and complexion change (such as from rosy to cyanotic or pale).

[0090] In this embodiment, the transportation system further includes an electrocardiograph monitor disposed in the casualty placement space, and the monitoring device further includes electrocardiogram electrode patches of the electrocardiograph monitor; the negative pressure fixing device is used to fix the electrocardiogram electrode patches to the electrocardiogram monitoring position of the casualty. After collecting the electrical activity data of the heart of the target casualty through the electrocardiogram electrode patches, determine the electrocardiogram waveform of the target casualty according to the electrical activity data of the heart, and determine the thoracic movement amplitude and respiratory rate of the target casualty according to the displacement data of the chest respiratory activity; then evaluate the physical condition of the target casualty according to the electrocardiogram waveform, carotid blood flow velocity, thoracic movement amplitude, and respiratory rate, so as to query the corresponding first aid measures for execution when the physical condition is an abnormal physical condition. This solution analyzes the cardiac electrical activity data to form an electrocardiogram waveform, and analyzes the displacement data of the chest respiratory activity to form the thoracic movement amplitude and respiratory rate, so as to comprehensively judge the physical condition of the casualty by combining data such as respiratory rate, thoracic activity, and blood flow. Compared with the method that only relies on a single parameter, the judgment of the physical condition is more comprehensive, stable, and has higher accuracy, can more accurately identify whether the casualty is in critical states such as cardiac arrest and respiratory failure, and automatically match the first aid measures according to the identified physical condition, forming a linkage process of identification → decision-making → execution, reducing the dependence on human judgment and accelerating the response speed, especially suitable for scenarios during transportation or remote operation.

[0091] In one embodiment, the physical state includes a state of cardiac and respiratory arrest. In step S32, that is, the control device queries the first aid measures taken for the target casualty according to the physical state of the target casualty, and is configured to perform the following steps: S321: Determine the screening conditions corresponding to the state of cardiac and respiratory arrest.

[0092] After determining the electrocardiogram waveform, thoracic movement amplitude, and respiratory rate of the target casualty, the control device obtains the screening conditions corresponding to multiple pre-stored physical states. Among them, the physical state at least includes the state of cardiac and respiratory arrest; the screening conditions corresponding to multiple physical states at least include the screening conditions corresponding to the state of cardiac and respiratory arrest.

[0093] Among them, the screening conditions corresponding to the state of cardiac and respiratory arrest include that the respiratory rate is less than the preset frequency, the electrocardiogram waveform indicates asystole, the thoracic movement amplitude is less than the preset activity degree, and the carotid blood flow velocity is less than the preset velocity.

[0094] S322: When the electrocardiogram waveform, carotid blood flow velocity, thoracic movement amplitude, and respiratory rate meet any two of the screening conditions corresponding to the state of cardiac and respiratory arrest, determine that the physical state of the target casualty is the state of cardiac and respiratory arrest.

[0095] The control device determines whether the electrocardiogram waveform, carotid blood flow velocity, thoracic movement amplitude, and respiratory rate meet the screening conditions corresponding to the state of cardiac and respiratory arrest, that is, determines whether the respiratory rate is less than the preset frequency, whether the electrocardiogram waveform indicates asystole, whether the thoracic movement amplitude is less than the preset activity degree, and whether the carotid blood flow velocity is less than the preset velocity.

[0096] When the electrocardiogram waveform, carotid blood flow velocity, thoracic movement amplitude, and respiratory rate meet any two of the screening conditions corresponding to the state of cardiac and respiratory arrest, determine that the physical state of the target casualty is the state of cardiac and respiratory arrest. That is, when any two of the respiratory rate of the target casualty being less than the preset frequency, the electrocardiogram waveform indicating asystole, the thoracic movement amplitude being less than the preset activity degree, and the carotid blood flow velocity being less than the preset velocity are satisfied, then the physical state of the target casualty is the state of cardiac and respiratory arrest.

[0097] In this embodiment, by determining the screening conditions corresponding to the state of cardiac and respiratory arrest, the screening conditions corresponding to the state of cardiac and respiratory arrest include a respiratory rate less than a preset rate, an electrocardiogram waveform indicating asystole, a thoracic movement amplitude less than a preset activity level, and a carotid blood flow velocity less than a preset velocity; when the electrocardiogram waveform, carotid blood flow velocity, thoracic movement amplitude, and respiratory rate meet any two of the screening conditions corresponding to the state of cardiac and respiratory arrest, it can be determined that the physical state of the target casualty is the state of cardiac and respiratory arrest. This solution constructs a multi-parameter fusion judgment mechanism by setting preset screening conditions for multiple physiological parameters and using the satisfaction of any two conditions as the standard for determining the state of cardiac and respiratory arrest, which not only improves the accuracy and intelligence of the judgment.

[0098] In one embodiment, the transportation system further includes a monitoring device installed in the casualty placement space. The monitoring device is used to monitor the physical changes of the target casualty in the casualty placement space, such as changes in limb movement, expression, etc., and the working conditions of various medical devices, such as changes in the electrocardiogram waveform in an electrocardiograph monitor, and changes in curves such as blood pressure and blood oxygen saturation. During the process of evaluating the physical state of the target casualty, the control device can monitor the limb movement and expression changes of the target casualty through the monitoring device, and comprehensively evaluate the physical state of the target casualty according to the collected data of the target casualty's blood pressure, blood oxygen saturation, carotid blood flow velocity, as well as electrocardiogram waveform, thoracic movement amplitude, and respiratory rate.

[0099] For example, using the image data or video data of the target casualty collected by the monitoring device, the pre-trained third neural network model (which can be a spatio-temporal graph convolutional network model) is used to identify the limb movement and expression changes of the target casualty to determine the limb movement state and expression state of the target casualty; for example, whether its limb movement state is an abnormal limb movement state such as limb twitching, and whether its expression state is an abnormal expression state such as restlessness, pain manifestation, or complexion change (such as from ruddy to cyanotic or pale). During the process of controlling the monitoring device to work, the monitoring device is controlled to execute a voice interaction process at a preset interaction frequency, or the monitoring device is controlled to execute a voice interaction process when it is determined that the expression state of the target casualty is an abnormal expression state to request the target casualty to interact, so as to determine the consciousness state of the target casualty according to the interaction result (such as voice feedback or limb feedback). Among them, during the voice interaction process, if the monitoring device does not collect the response voice or response limb movement of the target casualty within a certain period of time, it indicates that the target casualty is in a state of confusion, and the consciousness state of the target casualty is determined to be an abnormal consciousness state such as a state of confusion.

[0100] Meanwhile, determine the blood flow status of the target injured person according to the carotid blood flow velocity, determine whether the blood flow device is in an abnormal blood flow state such as too low blood flow, too high blood flow, or blood flow stop, determine the blood pressure status of the target injured person according to the blood pressure of the target injured person, determine whether the blood pressure status is an abnormal blood pressure state such as too low blood pressure or too high blood pressure, and determine the blood oxygen status of the target injured person according to the blood oxygen saturation, and determine whether the blood oxygen status is an abnormal blood oxygen state such as low blood oxygen saturation.

[0101] In addition, determine the electrocardiogram status of the target injured person according to the electrocardiogram waveform, determine whether the electrocardiogram status is an abnormal electrocardiogram state such as ventricular fibrillation state or cardiac arrest, and determine the breathing status of the target injured person according to the thoracic movement amplitude and breathing frequency, and determine whether the breathing status is an abnormal breathing state such as rapid breathing, slow breathing, breathing stop, or asymmetric breathing.

[0102] Finally, comprehensively evaluate the physical state of the target injured person according to the limb movement state, facial expression state, consciousness state, and blood flow state, blood pressure state, blood oxygen state, electrocardiogram state, and breathing state of the target injured person, so as to improve the comprehensiveness and accuracy of the judgment of the physical state of the injured person, provide an accurate data basis for the implementation of subsequent first aid measures, and improve the intelligence of the transportation system.

[0103] In one embodiment, the transportation system further includes an oxygen supply device installed in the injured person placement space; the oxygen supply device includes an oxygen delivery pipeline fixed in the injured person placement space, and an oxygen mask or oxygen delivery head that can be fixed to the mouth and nose of the injured person, and the oxygen mask (or oxygen delivery head) is connected to the oxygen delivery pipeline for delivering oxygen. After step S30, that is, after the control device queries the first aid measures corresponding to the physical abnormal state, it is further configured to perform the following steps: SA50: When the first aid measure indicates an oxygen supply operation, monitor whether the oxygen supply device is correctly worn at the mouth and nose of the target injured person through the monitoring device.

[0104] Among them, when it is determined that the physical state of the target injured person is the state of low blood oxygen saturation among the physical abnormal states, the first aid measure queried for the state of low blood oxygen saturation is an oxygen supply operation. When the first aid measure indicates an oxygen supply operation, it means that the target injured person is in an oxygen-deficient state, and the control device monitors whether the oxygen mask or oxygen delivery head of the oxygen supply device is correctly worn at the mouth and nose of the target injured person through the monitoring device.

[0105] Among them, when the blood oxygen saturation of the target injured person is lower than the threshold value, it can be determined that the physical state of the target injured person is the state of low blood oxygen saturation.

[0106] SA60: When it is monitored that the oxygen supply device is correctly worn at the mouth and nose of the target injured person, control the oxygen supply device to execute the oxygen output process.

[0107] When it is detected that an oxygen mask or an oxygen delivery head of an oxygen supply device is correctly worn at the mouth and nose of a target injured patient, the control device controls the oxygen supply device to execute an oxygen output process, and quickly and accurately delivers oxygen into the respiratory tract of the target injured patient, so as to increase the oxygen flow rate of the respiratory system thereof and quickly and effectively improve the anoxic state of the injured patient.

[0108] When it is detected that an oxygen mask or an oxygen delivery head of an oxygen supply device is not correctly worn at the mouth and nose of a target injured patient, the control device controls the oxygen supply device to start and execute an increased oxygen output process, so as to increase the oxygen content in the placement space of the injured patient, thereby increasing the amount of oxygen inhaled by the target injured patient and improving the anoxic state of the injured patient.

[0109] In this embodiment, the transportation system further includes a monitoring device and an oxygen supply device installed in the placement space of the injured patient. After querying the first-aid measures corresponding to the abnormal physical state, if the first-aid measures indicate performing an oxygen supply operation, the monitoring device monitors whether an oxygen supply device is correctly worn at the mouth and nose of the target injured patient, and when it is detected that the oxygen supply device is correctly worn at the mouth and nose of the target injured patient, the control device controls the oxygen supply device to execute an oxygen output process, and can quickly and accurately deliver oxygen into the respiratory tract of the target injured patient, quickly and effectively improving the anoxic state of the injured patient.

[0110] In one embodiment, the transportation system further includes a defibrillator. The main unit of the defibrillator is installed in the placement space of the injured patient. An electrode patch interface is provided on the main unit of the defibrillator.
