Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a transport system, a control device, equipment, a medium and a program product. Background Art

[0002] Currently, emergency medical transport of critically ill patients is primarily performed by land ambulance or air transport. During the transport process, accompanying medical personnel in the ambulance or air transport aircraft are required to promptly implement appropriate first aid measures based on the patient's actual physical condition to ensure their safety.

[0003] In traditional transport systems, first aid for patients relies heavily on the personal experience of medical staff. However, in actual applications, in situations where there are large numbers of casualties caused by natural disasters, wars, or major emergencies, there may be a shortage of rescue resources or medical personnel. Traditional transport systems cannot meet the transport needs of different scenarios, making it difficult to transport relevant personnel in a timely and safe manner, resulting in low transport efficiency and safety.

DETAILED DESCRIPTION

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0060] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of the described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or their collections. It should also be understood that the term "and / or" used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0061] In addition, in the description of the present specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0062] References to "one embodiment" or "some embodiments" in the present specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0063] It should be understood that the order of execution of the steps in the following embodiments does not necessarily mean the order in which they are executed. The order in which each process is executed should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0064] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0065] It's important to understand that the current emergency transport of critically ill patients requires accompanying medical personnel in ambulances or on transfer aircraft to promptly implement appropriate first aid measures based on the patient's actual physical condition to ensure their safety. Traditional transport systems rely heavily on the personal experience of medical personnel for first aid. However, in real-world applications, such as in the case of large numbers of casualties caused by natural disasters, wars, or major emergencies, rescue resources may be limited or medical personnel may be insufficient. Traditional transport systems struggle to meet the transport needs of various scenarios and are unable to provide timely and safe transport of relevant personnel, resulting in low transport efficiency and safety. With the increasing maturity of unmanned aerial vehicle (UAV) technology, providing a transport system capable of performing safe, unmanned transport is beneficial for meeting the transport needs of special scenarios such as mass casualties. This system can be used in both escorted and unaccompanied transport scenarios, improving the efficiency and safety of transporting the injured and sick.

[0066] Furthermore, because traditional transport procedures rely primarily on manual intervention, it's difficult to effectively monitor patients' vital signs and cannot automatically implement appropriate first aid measures based on their severity. This can lead to delays in first aid and the inability to perform them properly. For example, when a patient experiences cardiac arrest or respiratory failure, first aid personnel often rely on experience and manually perform chest compressions, a method that introduces delays and uncertainty.

[0067] In addition, due to the unstable operation of vehicles or aircraft during the transfer process, the posture of patients or injured persons is prone to change during the transfer process, and the relative position between relevant medical equipment and injured persons is unstable. It is often difficult to ensure that relevant equipment (such as vital sign monitoring equipment, compression devices and other medical emergency equipment) is always in the appropriate position, thereby affecting the monitoring accuracy of vital sign data and the first aid effect (such as chest compression effect).

[0068] In response to the above problems, the embodiments of the present application provide a transfer system, control device, equipment, medium and program product, which can provide an intelligent transfer system and its integrated equipment control solution to improve the automation and intelligence level of the transfer system. When rescue resources are tight or personnel are insufficient, the transfer system can still independently and efficiently perform first aid operations, meet the transfer needs of the wounded and sick in various scenarios, and improve the efficiency and safety of personnel transfer.

[0069] The transport system includes a negative pressure fixation device, a chest compression device, and a monitoring device, as well as a control device and a transport device with a space for placing the injured or sick; the negative pressure fixation device is used to fix the position of the injured or sick, and fix the chest compression device to the chest position of the injured or sick, and fix the monitoring device to the corresponding monitoring position of the injured or sick. The control device is configured to: during the process of transporting the target injured or sick via the transport device, control the monitoring device to monitor the target injured or sick's vital sign data, which includes displacement data of chest respiratory activity and the target injured or sick's carotid artery blood flow rate; based on the displacement data of chest respiratory activity and the carotid artery blood flow rate, evaluate the target injured or sick's physical condition, and when the physical condition is abnormal, query the first aid measures corresponding to the abnormal physical condition; when the first aid measures indicate chest compression, control the chest compression device located at the target injured or sick's chest to execute the chest compression process, and adjust the compression depth of the chest compression device according to the carotid artery blood flow rate. On the one hand, during the transfer process, the chest respiratory activity displacement data and carotid artery blood flow data of the target injured and sick are monitored through the monitoring device, which improves the continuity and accuracy of the vital sign data collection. Based on this, the respiratory condition and blood circulation condition of the injured and sick can be accurately assessed, so as to timely control the relevant devices to execute the chest compression process when assisting in judging the need for emergency measures such as chest compression, ensuring that the emergency operation is more accurate and timely, and ensuring the safety of relevant personnel; on the other hand, the transfer system provides an integrated vital sign monitoring and equipment control solution, which reduces human intervention during the transfer and emergency process, and improves the automation and intelligence level of the transfer system. When rescue resources are tight or personnel are insufficient, the transfer system can still independently and efficiently implement emergency operations, meeting the transfer needs of the injured and sick in various scenarios, and improving the efficiency and safety of personnel transfer.

[0070] The transfer system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the transport system includes a negative pressure immobilization device, a chest compression device, a monitoring device, a control device, and a transport device with space for placing the injured or sick. The negative pressure immobilization device and the chest compression device communicate with the detection and monitoring device via a network (such as a 5G network) or cables.

[0071] The negative pressure fixation device is used to secure the patient's position, preventing them from sustaining bodily harm due to sudden unstable positioning during transport. This is particularly effective in reducing secondary injuries to patients with spinal injuries and fractures. Furthermore, the negative pressure fixation device is used to secure the chest compression device to the patient's chest and the monitoring device to the patient's corresponding monitoring position, preventing instability in the relative position between the device and the patient during transport, which could affect the accuracy of vital sign data monitoring and the effectiveness of first aid.

[0072] Specifically, the control device is configured to: during the process of transporting the target patient via the transport device, the control device controls the monitoring device fixed on the target patient to monitor the target patient's physical condition in real time, that is, to monitor the target patient's vital sign data in real time, for example, to monitor the displacement data of the target patient's chest respiratory activity and the carotid blood flow rate, that is, the vital sign data at least includes the displacement data of the target patient's chest respiratory activity and the carotid blood flow rate. The control device evaluates the target patient's physical condition based on the displacement data of the chest respiratory activity and the carotid blood flow rate, and when the physical condition is abnormal, queries the first aid measures corresponding to the abnormal physical condition; when the first aid measures indicate chest compression, the control device controls the chest compression device located at the target patient's chest to execute the chest compression process, and adjusts the compression depth of the chest compression device according to the carotid blood flow rate.

[0073] The transfer system in this embodiment monitors the chest respiratory activity displacement data and carotid artery blood flow data of the target injured or sick person through a monitoring device during the transfer process, thereby improving the continuity and accuracy of the vital sign data collection. Based on this, the respiratory condition and blood circulation condition of the injured or sick person can be accurately assessed, so as to timely control the relevant devices to execute the chest compression process when assisting in determining the need for emergency measures such as chest compression, ensuring that the emergency operation is more accurate and timely, and guaranteeing the safety of relevant personnel. The transfer system provides an integrated vital sign monitoring and equipment control solution, which reduces human intervention during the transfer and emergency process, improves the automation and intelligence level of the transfer system, and when rescue resources are tight or personnel are insufficient, the transfer system can still independently and efficiently implement emergency operations, meeting the transfer needs of the injured or sick in various scenarios, and improving the efficiency and safety of personnel transfer.

[0074] The monitoring device can be an electronic device installed within a transportation device (e.g., a vehicle or aircraft). For example, the monitoring device can be a personal computer, laptop, smartphone, tablet computer, or portable wearable device installed within the transportation device. The monitoring device can also be installed on a server external to the transportation device, such as a cloud server. This server can be implemented as a standalone server or a server cluster consisting of multiple servers.

[0075] To explain the structure and function of the transfer system in this embodiment in detail, Figures 2 to 7 The functions and implementation principles of each device in the transfer system are explained.

[0076] In one embodiment, if Figure 2 As shown, the control device in the transfer system is configured to perform the following steps:

[0077] S10: During the process of transporting the target patient via the transport device, the monitoring device is controlled to monitor the vital sign data of the target patient, where the vital sign data includes displacement data of chest respiratory activity and carotid artery blood flow velocity of the target patient.

[0078] The transfer system provided in this embodiment includes a negative pressure fixing device, a chest compression device and a monitoring device, as well as a transport device with a space for placing the injured or sick. The negative pressure fixing device is a portable fixing device that is used to fix the position of the injured or sick to avoid physical injuries caused by sudden unstable position of the injured or sick during the transfer process. In addition, the negative pressure fixing device is also used to fix the chest compression device to the chest position of the injured or sick, and to fix the monitoring device to the corresponding monitoring position of the injured or sick, to avoid the situation in which the relative position between the equipment and the injured or sick is unstable during the transfer process, which affects the monitoring accuracy of the vital sign data and the first aid effect.

[0079] During actual application, relevant personnel (such as medical staff or the injured person himself) transfer the target injured person to the injured person placement space of the transportation device, and fix the negative pressure fixation device at the corresponding position of the target injured person, so that the position of the target injured person in the injured person placement space is fixed, and the transportation device is operated to transfer the target injured person to the designated location.

[0080] Among them, in the process of transporting the target injured person through the transportation device, the control device controls the monitoring device to monitor the physical condition of the target injured person in real time, that is, to monitor the vital sign data of the target injured person in real time, for example, monitoring the displacement data of the chest respiratory activity and the carotid blood flow rate of the target injured person, that is, the vital sign data at least includes the displacement data of the chest respiratory activity of the target injured person, and the carotid blood flow rate, to assist in determining whether relevant first aid operations can be performed on the target injured person.

[0081] S20: Assess the physical condition of the target casualty based on chest respiratory activity displacement data and carotid artery blood flow velocity.

[0082] In the process of monitoring the vital sign data of the target patient, that is, collecting the displacement data of the chest respiratory activity and the carotid blood flow velocity of the target patient, the control device can evaluate the physical condition of the target patient based on the displacement data of the chest respiratory activity and the carotid blood flow velocity.

[0083] Among them, the control device can determine the chest movement amplitude and respiratory rate of the target patient based on the displacement data of the chest respiratory activity. The chest movement amplitude is the amplitude of the chest's rise and fall when the human body breathes, that is, the displacement of the chest's up and down movement when the human body breathes, and is determined by the difference in displacement values measured when the target patient exhales and inhales. One rise and fall of the human chest is one breath, that is, one inhalation and one exhalation is one breath, and the respiratory rate is the number of breaths per minute. The time required for one breath is determined by the displacement data of the chest respiratory activity, that is, each increase and decrease in the displacement of the chest is one breath, and the time required for the exhalation is determined, and then the number of breaths per minute is predicted, that is, the respiratory rate is obtained.

[0084] After obtaining the target patient's chest movement amplitude and respiratory rate, the control device can assess the target patient's physical condition based on the carotid blood flow velocity, chest movement amplitude, and respiratory rate. The carotid blood flow velocity, chest movement amplitude, and respiratory rate of the living person can represent the changes in the target patient's vital signs. The carotid blood flow velocity, chest movement amplitude, and respiratory rate can be used to quickly determine whether the living person is in danger of death, thereby quickly assisting in determining whether to implement corresponding first aid measures.

[0085] For example, when the carotid artery blood flow velocity (or blood flow) of the target patient is monitored to be 0, that is, the carotid artery blood flow and cardiac arrest are not monitored, and the chest movement amplitude and respiratory rate are monitored to be 0, it is determined that the physical condition of the target patient is in a state of cardiac and respiratory arrest, and cardiopulmonary resuscitation first aid measures can be taken for the target patient to restore the heartbeat and breathing of the target patient in time.

[0086] In other embodiments, when the carotid artery blood flow velocity, thoracic movement amplitude, and respiratory rate meet any two of the screening conditions corresponding to cardiac and respiratory arrest, the target patient's physical condition is determined to be in cardiac and respiratory arrest. Screening conditions corresponding to cardiac and respiratory arrest include: respiratory rate less than a preset frequency, thoracic movement amplitude less than a preset range of motion, and carotid artery blood flow velocity less than a preset flow rate. By determining the two screening conditions corresponding to cardiac and respiratory arrest, the possibility of misjudgment can be reduced, the accuracy of judgment can be improved, and the patient's safety can be ensured. The preset frequency can be a frequency value of 0 or close to 0 (e.g., 1 beat / min); the preset range of motion can be a value of 0 or close to 0 (e.g., 0.1 cm); and the preset flow rate can be a flow rate value of 0 or close to 0 (e.g., 1 cm / s).

[0087] S30: When the physical state is an abnormal physical state, query the first aid measures corresponding to the abnormal physical state.

[0088] The control device pre-stores first aid measures corresponding to different physical conditions. After assessing the physical condition of the target patient, the control device determines whether the condition is abnormal. If the condition is abnormal, the control device queries the first aid measures corresponding to the abnormal condition and controls the relevant equipment to execute the corresponding first aid process based on the first aid measures.

[0089] Among them, abnormal physical conditions may also include respiratory and cardiac arrest, shock, ventricular fibrillation, hypoxia, and abnormal respiratory conditions such as rapid exhalation and slow exhalation; they also include abnormal blood pressure conditions such as low blood pressure and high blood pressure, abnormal blood flow conditions such as low blood flow, high blood flow or blood flow cessation, and abnormal blood oxygen conditions such as low blood oxygen saturation.

[0090] In one embodiment, a pre-trained first neural network model can be used to perform motion analysis on the target patient's chest respiratory movement displacement data to obtain the target patient's chest movement amplitude and respiratory rate. Based on this analysis, the target patient's respiratory state can be predicted to determine whether the target patient's respiratory state is abnormal, such as tachypnea, asymmetric breathing, or respiratory arrest. Subsequently, a pre-trained second neural network model can be used to perform blood flow state identification on the collected carotid artery blood flow velocity of the target patient to obtain the target patient's blood flow state and determine whether the target patient's blood flow state is abnormal. If the target patient's respiratory state is abnormal or their blood flow state is abnormal, the target patient's physical condition is assessed as abnormal, and corresponding emergency measures are determined based on the abnormal physical condition (e.g., abnormal respiratory state or abnormal blood flow state).

[0091] 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.

[0092] S40: When the first aid measure indicates to perform chest compression, the chest compression device located at the chest of the target patient is controlled to execute the chest compression process, and the compression depth of the chest compression device is adjusted according to the carotid artery blood flow rate.

[0093] When the first aid measures indicate chest compression, the control device can control the chest compression device located at the chest of the target patient to perform the chest compression process to restore the heartbeat and breathing of the target patient in time.

[0094] For example, the monitoring device may include a displacement sensor for monitoring the displacement of the chest cavity during respiratory activity, and an ultrasonic blood flow sensor for monitoring carotid artery blood flow velocity and blood volume. When the target patient's heart is beating normally, the ultrasonic blood flow sensor will monitor the blood flow through the carotid artery and, through continuous data acquisition, generate basic parameters such as the patient's carotid artery blood flow and blood velocity. When the target patient experiences cardiac arrest, the ultrasonic blood flow sensor will detect no blood flow, meaning that the patient's carotid artery blood flow and blood velocity are zero. The control device then uses the displacement data collected by the chest displacement sensor to determine whether the target patient is experiencing an emergency situation of cardiac and respiratory arrest (i.e., the target patient's physical condition is in cardiac and respiratory arrest). If this emergency situation is determined to be the case, the control device queries for emergency measures corresponding to cardiac and respiratory arrest to activate the chest compression device to perform the external chest compression process.

[0095] In the process of controlling the chest compression device to perform external chest compressions, 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 damage to the human body caused by excessive compression. During the external chest compression process, if the carotid blood flow velocity increases, the compression depth of the chest compression device is reduced; if 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 flow rate value (and the chest wall movement amplitude reaches the calibrated value), the chest compression device is controlled to stop compressions.

[0096] The transport system in this embodiment monitors the target patient's vital sign data, such as chest respiratory activity displacement data and carotid artery blood flow data, through a monitoring device during the transport process. This can improve the continuity and accuracy of vital sign data collection, and can accurately assess the patient's respiratory and blood circulation conditions based on this data. When assisting in determining the need for emergency measures such as chest compressions, the system can promptly control the relevant devices to execute the chest compression process, ensuring that the emergency operation is more accurate and timely, and ensuring the safety of relevant personnel. At the same time, the transport system provides an integrated patient vital sign monitoring and medical equipment control solution, which reduces human intervention during the transport and emergency treatment process, improves the automation and intelligence level of the transport system, and when rescue resources are tight or personnel are insufficient, the transport system can still independently and efficiently implement emergency operations, reducing dependence on medical staff, meeting the transport needs of patients in various scenarios, and improving the efficiency and safety of personnel transport.

[0097] In one embodiment, after querying the first aid measures corresponding to the abnormal physical state, the control device can send the carotid blood flow velocity, chest movement amplitude and respiratory rate, as well as the first aid measures taken, to the terminal device of the medical staff, requesting the medical staff to confirm whether to execute the first aid measures based on the sent data; after receiving the confirmation instruction from the medical staff, the chest compression device located at the chest of the target patient is controlled to execute the chest compression process and adjust the compression depth of the chest compression device according to the carotid blood flow velocity. The relevant first aid measures are only executed after confirmation by professionals, avoiding physical injuries caused by the machine's incorrect recognition and execution of first aid, improving the accuracy of the chest compression process execution, and enhancing the safety of the patient.

[0098] If no confirmation or cancellation instructions from medical staff are received within a preset time (e.g., 2 minutes), the control device directly controls the chest compression device located on the target patient's chest to perform chest compressions, adjusting the compression depth based on carotid blood flow. This solution avoids delays in emergency care caused by signal interruptions or staff absence, ensuring timely first aid and improving patient safety.

[0099] In one embodiment, if Figure 3 As shown, the monitoring device of the transport 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 displacement changes of the patient's chest movement. The second flexible sensor 22 is a blood flow sensor made of flexible material for monitoring the blood flow and blood flow velocity in the patient's carotid artery. The second flexible sensor 22 can be an ultrasonic blood flow sensor made of flexible material for measuring carotid blood flow and blood flow velocity.

[0100] In this solution, the flexible sensor can conform to the changes in the curvature of the chest and neck, and fit the target area after being fixed, effectively reducing displacement and interference, thereby improving the accuracy of collecting chest respiratory activity displacement data and carotid artery blood flow data, and providing a reliable basis for subsequent judgment of respiratory and circulatory status.

[0101] The negative pressure fixation device includes a flexible fixation device 1, a negative pressure device (not shown), and a communication device (which may be a 5G communication device). The negative pressure device is located within the flexible fixation device. When the negative pressure device is in operation, the flexible fixation device wraps around the patient's torso and neck. A first flexible sensor 21 and a second flexible sensor 22 are electrically connected to the communication device. The first flexible sensor 21 and the second flexible sensor 22 are located at corresponding positions on the flexible fixation device 1.

[0102] 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 control signals from the control device, and to transmit data collected by the first flexible sensor 21 and the second flexible sensor 22 to the control device. In this solution, the negative pressure fixation device controls the flexible fixation device 1 to surround and conform to the torso and neck of the target patient. This not only quickly stabilizes the patient's position but also accurately positions the sensors and chest compression device to the critical areas of the patient's chest and neck, improving the device's positioning accuracy and functional reliability.

[0103] In one embodiment, if Figure 3 As shown, the flexible fixation 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 patient; the second part 12 is used to cover and fix the neck of the patient. The cavities of the first part 11 and the second part 12 are connected. The first part 11 of the flexible fixation device 1 is also provided with an exhaust structure 51. When the flexible fixation device 1 performs negative pressure fixation on the patient, the negative pressure transfer station extracts and releases gas through the exhaust structure 51, so that when the negative pressure device is in operation, the first part 11 of the flexible fixation device 1 is fixed around the torso of the patient, and the second part 12 of the flexible fixation device 1 is fixed around the neck of the patient.

[0104] In other embodiments, the cavities of the first part 11 and the second part 12 are not connected, that is, the first part 11 and the second part 12 can be two independent parts, and the cavity contents of the first part 11 and the second part 12 are both provided with a negative pressure device and an exhaust structure 51, so that after the negative pressure device is operated, the first part 11 of the flexible fixing device 1 is surrounded and fixed on the torso of the injured person, and after the negative pressure device is operated, the second part 12 of the flexible fixing device 1 is surrounded and fixed on the neck of the injured person, thereby improving the fixing effect of the flexible fixing device 1.

[0105] The negative pressure device includes a vacuum pump (not shown), a power source for the vacuum pump (i.e., a first power source) 41, and a negative pressure line (not shown). The negative pressure line is disposed within a cavity within at least one of the first portion 11 and the second portion 12. When the flexible fixation device 1 needs to be negatively immobilized or released, the exhaust structure 51 is controlled to open, and the negative pressure device is controlled to operate, causing the flexible fixation device 1 to perform other pumping and release operations, thereby enabling the flexible fixation device 1 to surround and secure the corresponding body part of the patient or release the patient. The negative pressure line can be made of medical silicone, making it flexible, pressure-resistant, and autoclavable.

[0106] 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 further provided with a sealing structure (such as a sealing gasket, a sealing ring) for inserting other devices. For example, the first flexible sensor 21 is installed at a corresponding position of the first part 11 through the sealing structure, such as being installed in the first part 11 at a position relative to the chest of the patient; the second flexible sensor 22 is installed at a corresponding position of the second part 12 through the sealing structure, such as being installed in the second part 12 at a position relative to the artery of the patient's neck. In order to improve the accuracy of chest respiratory activity displacement data, the number of first flexible sensors 21 can be 4; in order to improve the accuracy of blood flow data (blood volume and blood flow velocity), the number of second flexible sensors 22 can be 2, such as Figure 3 The sealing structure may be a sealing gasket or a sealing ring made of silicone or fluororubber to ensure airtightness.

[0107] 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. Figure 4 As shown, the flexible fixture consists of an outer silicone layer, a polyvinyl alcohol foam layer, and an inner silicone layer, with the negative pressure device positioned within the polyvinyl alcohol foam layer. The inner silicone layer, which contacts the patient's skin, features a sealing structure on the side of the silicone layer that contacts the patient's skin, accommodating the first flexible sensor 21 and the second flexible sensor 22. Furthermore, a sealing interface is provided at the edge of the outer silicone layer for inserting the power supply of the negative pressure device, ensuring airtightness.

[0108] In one embodiment, if Figure 3 As shown, the chest compression device is mounted on the flexible fixing device 1 of the negative pressure fixation device via a retractable, position-adjustable fixing strap 7. The chest compression device includes a power supply (i.e., a second power supply) 61, a pneumatic compression device 62, a sternal compression pad 63, a pneumatic compression spring device 64 with adjustable compression depth, and a communication device. The pneumatic compression device 62 is located within the fixing strap 7 and provides power to compress or release the pneumatic compression spring device 64 to perform chest compressions on the patient. The communication device is used to start and stop the chest compression device in response to control signals from the control device and transmit operating data of the chest compression device to the control device.

[0109] Among them, such as Figure 3 As shown, the chest compression device may further include a buckle 65, which may be connected to a patient placement platform in a transport stretcher or a transportation device to fix the negative pressure fixing device with the chest compression device on the transport stretcher or the patient placement platform, and achieve position fixation of the patient.

[0110] The negative pressure fixation device may also include a start switch (not shown) that is used to start and stop the negative pressure fixation device. Before or during the transfer of the patient, the medical staff or the patient themselves wrap the flexible fixation device around the patient's torso and neck, so that the various sensors and chest compression devices are located in the corresponding positions of the patient. The exhaust device is then turned on, the power supply of the negative pressure device is activated, and the negative pressure device mechanically evacuates air to form negative pressure fixation. Afterwards, the medical staff or patient turns on the start switch, causing it to send a start signal to the control device to initiate the monitoring process.

[0111] In one embodiment, if Figure 5 As shown, in step S10, the control device controls the monitoring device to monitor the displacement data of the chest respiratory activity of the target patient and the carotid artery blood flow velocity of the target patient, and is configured to perform the following steps:

[0112] S11: Receive a start signal of the negative pressure fixing device.

[0113] The negative pressure immobilization device may also include an activation switch for starting and stopping the device. After the relevant personnel (medical staff or patient) secure the flexible immobilization device around the patient, ensuring that the first and second flexible sensors are respectively attached to the patient's chest and neck, and the chest compression device is positioned at the patient's chest compression position, they can turn on the activation switch to send an activation signal for the negative pressure immobilization device to the control device. The control device then receives the activation signal.

[0114] That is, the start signal is used to instruct the flexible fixing device to be fixed around the torso and neck of the target injured person, and to instruct the first flexible sensor and the second flexible sensor to be fixed on the chest and neck of the target injured person respectively, and to instruct the chest compression device to be located at the chest compression position of the target injured person.

[0115] S12: Control the first flexible sensor to collect displacement data of the chest respiratory activity of the target patient, and control the second flexible sensor to collect the carotid artery blood flow velocity of the target patient.

[0116] After the control device receives the start signal of the negative pressure fixation device, it can determine that the flexible fixation device is fixed around the torso and neck of the target injured person, the first flexible sensor and the second flexible sensor are fixed on the chest and neck of the target injured person respectively, and the chest compression device is located at the chest compression position of the target injured person, then the first flexible sensor is controlled to collect the displacement data of the chest respiratory activity of the target injured person, and the second flexible sensor is controlled to collect the carotid artery blood flow velocity of the target injured person.

[0117] In this embodiment, a control device receives an activation signal from a negative pressure fixation device. The activation signal instructs the flexible fixation device to wrap around and secure the target patient's torso and neck, instructs the first and second flexible sensors to be secured to the target patient's chest and neck, and instructs the chest compression device to be positioned at the target patient's chest compression position. The control device controls the first flexible sensor to collect displacement data of the target patient's chest respiratory activity, and controls the second flexible sensor to collect blood flow data from the target patient's carotid artery. This solution, through coordinated control of the control device, the negative pressure fixation structure, the flexible sensor, and the chest compression device, achieves automated positioning and stable fixation of key areas of the patient's chest and neck, ensuring that the vital sign collection device collects target vital sign data with high conformity and sensitivity. This significantly improves the accuracy of the patient's vital sign monitoring, the timeliness of the system response, and the effectiveness of subsequent emergency response. Upon receiving the activation signal, the control device automatically completes the fixation action and simultaneously controls the initiation of the data collection process, forming an automated process from device deployment → fixation → activation → vital sign monitoring, thereby improving the device's responsiveness and operational efficiency.

[0118] In one embodiment, the transport system further includes an ECG monitor positioned within the patient placement space; the monitoring device further includes ECG electrodes for the ECG monitor; and a negative pressure securing device is configured to secure the ECG electrodes to the patient's ECG monitoring position. The ECG monitoring positions may include three monitoring positions: the left upper chest, the right upper chest, and the left lower chest (or right lower chest). The left upper chest monitoring position is located at the first intercostal space between the left edge of the sternum and the midclavicular line; the right upper chest monitoring position is located at the first intercostal space between the right edge of the sternum and the midclavicular line; and the left lower chest (or right lower chest) monitoring position is located at the costal margin of the left (or right) midclavicular line. The ECG monitor is provided with an electrode interface, which allows the ECG monitor to be detachably connected to the ECG electrodes via the electrode interface.

[0119] Before or during the transfer of the injured patient, the medical staff or the injured patient themselves will wrap the flexible fixing device around the torso and neck of the injured patient so that various sensors and chest compression devices are located at the corresponding positions of the injured patient. Then the exhaust device will be turned on, the power supply of the negative pressure device will be started, and the negative pressure device will be mechanically evacuated to form a negative pressure fixation. Afterwards, the medical staff or the injured patient turns on 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 instruct the flexible fixing device to be fixed around the torso and neck of the target injured patient, and to instruct the first flexible sensor and the second flexible sensor to be fixed to the chest and neck of the target injured patient respectively, and to instruct the chest compression device to be located at the chest compression position of the target injured patient, and to instruct the ECG electrode to be fixed at the ECG monitoring position of the target injured patient.

[0120] After step S11, that is, after the control device receives the start signal of the negative pressure fixation device, the control device controls the first flexible sensor to collect the displacement data of the chest respiratory activity of the target patient, and controls the second flexible sensor to collect the carotid artery blood flow velocity of the target patient, and controls the ECG electrode to collect the electrical activity data of the heart of the target patient to obtain the vital sign data of the target patient, and increases the sensor type to collect different types of vital sign data of the patients, so as to facilitate the subsequent judgment of the patient's physical condition according to each type and improve the accuracy of the judgment.

[0121] In other embodiments, the ECG monitor is also connected to sensors such as a blood pressure sensor and a blood oxygen sensor to collect vital signs data such as the blood pressure and blood oxygen saturation of the target patient, and monitor changes in the ECG, blood pressure, blood oxygen saturation, etc. of the target patient through the ECG monitor.

[0122] After the patient is transferred to the transport device, during the transfer process, the medical staff or the patient themselves wraps the flexible fixation device around the patient's torso and neck, positioning the various sensors and chest compression device in the corresponding positions on the patient. The exhaust device is then turned on, and the power to the negative pressure device is activated. The negative pressure device mechanically pumps air to create a negative pressure fixation. Simultaneously, the blood pressure sensor and blood oxygen sensor are placed in the corresponding monitoring positions on the patient. The medical staff or patient then turns on the start switch, which sends a start signal to the control device to initiate the monitoring process.

[0123] In one embodiment, the target patient's vital sign data also includes the target patient's heart electrical activity data, such as Figure 6 As shown, in step S30, the control device evaluates the physical condition of the target patient based on the displacement data of the chest respiratory activity and the carotid artery blood flow velocity, and is configured to perform the following steps:

[0124] S31: Determine the electrocardiogram waveform of the target patient based on the heart's electrical activity data.

[0125] In this embodiment, the target patient's vital sign data also includes the target patient's heart electrical activity data. After acquiring the target patient's heart electrical activity data, the control device can determine the target patient's electrocardiogram waveform based on the target patient's heart electrical activity data.

[0126] S32: Determine the chest movement amplitude and respiratory rate of the target patient based on the displacement data of the chest respiratory activity.

[0127] The target patient's chest displacement data can be monitored using a three-dimensional displacement sensor. Specifically, the monitoring device includes a three-dimensional displacement sensor. The three-dimensional displacement sensor collects displacement data of the target patient's chest displacement data, thereby determining the target patient's chest movement amplitude and respiratory rate. The chest movement amplitude can include chest movement amplitudes in different directions; the chest movement amplitude can also be a single amplitude value determined based on the chest movement displacement values in different directions.

[0128] The displacement data of the chest respiratory activity of the target patient can be collected by the three-dimensional displacement sensor, that is, the chest movement direction and chest movement amplitude of the target patient in a certain period of time can be extracted by the sensor, and the chest movement (fluctuation) state of the target patient's respiratory activity in 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), and Y axis (axis perpendicular to the horizontal and vertical axes) respectively represent the vertical displacement value, horizontal displacement value, and displacement value perpendicular to the vertical and horizontal directions during chest breathing activity collected by the three-axis sensor.

[0129] S33: Assess the physical condition of the target casualty based on the electrocardiogram waveform, carotid artery blood flow velocity, chest movement amplitude and respiratory rate.

[0130] After determining the target patient's electrocardiogram waveform, chest movement amplitude, and respiratory rate, the control device evaluates the target patient's physical condition based on the electrocardiogram waveform, chest movement amplitude, respiratory rate, and the collected carotid artery blood flow velocity, and determines whether the physical condition is an abnormal physical state. When the physical condition is an abnormal physical state, the control device queries the first aid measures corresponding to the abnormal physical state based on the target patient's physical condition, and controls the relevant equipment to execute the corresponding first aid process based on the first aid measures. For example, when the physical condition is determined to be an abnormal physical state, such as cardiac and respiratory arrest, the control device queries the first aid measures corresponding to the cardiac and respiratory arrest, such as chest compression operations.

[0131] In other embodiments, abnormal physical conditions may also include states such as shock, ventricular fibrillation, hypoxia, abnormal respiratory conditions such as rapid or slow exhalation, abnormal blood pressure such as low or high blood pressure, abnormal blood flow such as low, high, or stopped blood flow, and abnormal blood oxygen saturation such as low blood saturation. Abnormal physical conditions may also include abnormal limb movements such as convulsions, abnormal facial expressions such as restlessness, expressions of pain, and changes in facial color (e.g., from rosy to cyanotic or pale).

[0132] In this embodiment, the transport system also includes an electrocardiogram (ECG) monitor set in the space where the patient is placed, and the monitoring device also includes ECG electrodes for the ECG monitor; a negative pressure fixing device is used to fix the ECG electrodes to the ECG monitoring position of the patient. After the electrical activity data of the heart of the target patient is collected by the ECG electrodes, the ECG waveform of the target patient is determined based on the electrical activity data of the heart, and the chest movement amplitude and respiratory rate of the target patient are determined based on the displacement data of the chest respiratory activity; after accommodation, the physical condition of the target patient is evaluated based on the ECG waveform, carotid artery blood flow velocity, chest movement amplitude and respiratory rate, so that when the physical condition is abnormal, the corresponding first aid measures are queried for execution. This solution forms an ECG waveform by analyzing the electrical activity data of the heart, and forms the chest movement amplitude and respiratory rate by analyzing the displacement data of the chest respiratory activity, thereby comprehensively judging the physical condition of the patient by combining data such as respiratory rate, chest movement and blood flow. Compared with the method that relies solely on a single parameter, physical condition judgment is more comprehensive, stable, and more accurate. It can more accurately identify whether the injured person is in a critical state such as cardiac arrest or respiratory failure, and automatically match first aid measures based on the identified physical condition, forming an interactive process of identification → decision-making → execution, reducing reliance on human judgment and speeding up response. It is especially suitable for transportation or remote operation scenarios.

[0133] In one embodiment, the physical condition includes a cardiac and respiratory arrest state. In step S32, the control device queries the first aid measures to be taken for the target patient according to the physical condition of the target patient, and is configured to perform the following steps:

[0134] S321: Determine the screening conditions corresponding to the cardiac and respiratory arrest state.

[0135] After determining the target patient's electrocardiogram waveform, chest movement amplitude, and respiratory rate, the control device retrieves pre-stored screening conditions corresponding to multiple physical states. The physical states include at least cardiac and respiratory arrest, and the screening conditions corresponding to the multiple physical states include at least a screening condition corresponding to cardiac and respiratory arrest.

[0136] Among them, the screening conditions corresponding to the cardiac and respiratory arrest state include respiratory rate less than the preset frequency, electrocardiogram waveform indicating ventricular arrest, chest movement amplitude less than the preset activity, and carotid artery blood flow velocity less than the preset flow velocity.

[0137] S322: When the electrocardiogram waveform, carotid artery blood flow velocity, chest movement amplitude and respiratory rate meet any two of the screening conditions corresponding to the cardiac and respiratory arrest state, the physical condition of the target patient is determined to be the cardiac and respiratory arrest state.

[0138] The control device determines whether the electrocardiogram waveform, carotid artery blood flow velocity, chest movement amplitude and respiratory rate are triggered to meet the screening conditions corresponding to the cardiac and respiratory arrest state, that is, whether the respiratory rate is less than the preset frequency, whether the electrocardiogram waveform indicates ventricular arrest, whether the chest movement amplitude is less than the preset activity, and whether the carotid artery blood flow velocity is less than the preset flow rate.

[0139] The target patient's physical condition is determined to be in cardiorespiratory arrest when any two of the screening conditions corresponding to cardiac and respiratory arrest are met, as determined by the electrocardiogram waveform, carotid artery blood flow velocity, thoracic movement amplitude, and respiratory rate. Specifically, the target patient's physical condition is determined to be in cardiorespiratory arrest when any two of the following conditions are met: the target patient's respiratory rate is less than a preset rate, the electrocardiogram waveform indicates ventricular arrest, the thoracic movement amplitude is less than a preset range of motion, and the carotid artery blood flow velocity is less than a preset flow rate.

[0140] In this embodiment, by determining the screening conditions corresponding to the cardiorespiratory arrest state, the screening conditions corresponding to the cardiorespiratory arrest state include a respiratory rate less than a preset frequency, an electrocardiogram waveform indicating ventricular arrest, a chest movement amplitude less than a preset activity, and a carotid artery blood flow velocity less than a preset flow velocity; when the electrocardiogram waveform, carotid artery blood flow velocity, chest movement amplitude, and respiratory rate meet any two of the screening conditions corresponding to the cardiorespiratory arrest state, the physical condition of the target patient can be determined to be a cardiorespiratory arrest state. 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 cardiorespiratory arrest state, which not only improves the accuracy and intelligence of the judgment.

[0141] In one embodiment, the transport system further includes a monitoring device installed within the patient placement space. The monitoring device is used to monitor physical changes of the target patient within the patient placement space, such as changes in limb movements and facial expressions, as well as the operating conditions of various medical devices, such as changes in the electrocardiogram waveform of an electrocardiogram monitor, and changes in blood pressure, blood pressure saturation, and other curves. During the assessment of the target patient's physical condition, the control device can monitor the target patient's limb movements and facial expressions through the monitoring device, and comprehensively assess the target patient's physical condition based on the collected data such as the target patient's blood pressure, blood oxygen saturation, carotid artery blood flow velocity, electrocardiogram waveform, chest movement amplitude, and respiratory rate.

[0142] For example, using the target patient's image or video data collected by the monitoring device, a pre-trained third neural network model (which can be a spatiotemporal graph convolutional network model) is used to identify the target patient's limb movements and facial expressions to determine the target patient's limb movement state and facial expression state. For example, whether the target patient's limb movement state is abnormal, such as twitching, or whether the target patient's facial expression is abnormal, such as irritability, pain, or facial color change (such as from rosy to cyanotic or pale). During the process of controlling the monitoring device, the monitoring device is controlled to execute a voice interaction process at a preset interaction frequency. Alternatively, if the target patient's facial expression is determined to be abnormal, the monitoring device is controlled to execute a voice interaction process to request the target patient to interact. The target patient's state of consciousness is then determined based on the interaction results (such as voice feedback or body feedback). During the voice interaction process, if the monitoring device does not capture the target patient's response voice or body movement within a certain period of time, it indicates that the target patient's consciousness is blurred, and the target patient's consciousness state is determined to be abnormal, such as blurred consciousness.

[0143] At the same time, the blood flow status of the target patient is determined based on the carotid artery blood flow velocity, and 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 cessation. The blood pressure status of the target patient is determined based on the blood pressure of the target patient, and whether the blood pressure status is an abnormal blood pressure state such as too low blood pressure, too high blood pressure, etc. The blood oxygen status of the target patient is determined based on the blood oxygen saturation, and whether the blood oxygen status is an abnormal blood oxygen state such as low blood oxygen saturation.

[0144] In addition, the ECG state of the target patient is determined based on the ECG waveform to determine whether the ECG state is considered to indicate an abnormal ECG state such as ventricular fibrillation or cardiac arrest. The respiratory state of the target patient is determined based on the chest movement amplitude and respiratory rate to determine whether the respiratory state is an abnormal respiratory state such as too fast breathing, too slow breathing, respiratory arrest, or asymmetric breathing.

[0145] Finally, the physical condition of the target casualty is comprehensively assessed based on their limb movement status, facial expression status, consciousness status, as well as blood flow status, blood pressure status, blood oxygen status, electrocardiogram status and respiratory status, so as to improve the comprehensiveness and accuracy of the judgment of the casualty's physical condition, provide an accurate data basis for the implementation of subsequent first aid measures, and improve the intelligence of the transfer system.

[0146] In one embodiment, the transport system further includes an oxygen supply device installed within the patient accommodation space; the oxygen supply device includes an oxygen delivery pipeline secured within the patient accommodation space, and an oxygen mask or oxygen delivery head that can be secured to the patient's mouth and nose. The oxygen mask (or oxygen delivery head) is connected to the oxygen delivery pipeline for oxygen delivery. After step S30, i.e., after the control device queries for emergency measures corresponding to the abnormal physical condition, it is further configured to execute the following steps:

[0147] SA50: When first aid measures indicate the need to administer oxygen, use a monitoring device to monitor whether the target patient is wearing the oxygen device correctly around their mouth and nose.

[0148] When the target patient's physical condition is determined to be low oxygen saturation among the abnormal physical conditions, the first aid measure corresponding to the low oxygen saturation condition is checked, and the first aid measure is oxygen administration. When the first aid measure indicates oxygen administration, indicating that the target patient is in a state of hypoxia, the control device uses the monitoring device to monitor whether the target patient is properly wearing the oxygen mask or oxygen delivery head of the oxygen supply device at the mouth and nose.

[0149] When the blood oxygen saturation of the target patient is lower than a threshold value, it can be determined that the physical condition of the target patient is a state of low blood oxygen saturation.

[0150] SA60: When it is detected that the target patient is wearing the oxygen supply device correctly around their mouth and nose, the oxygen supply device is controlled to execute the oxygen output process.

[0151] When it is monitored that the target patient is correctly wearing the oxygen mask or oxygen delivery head of the oxygen supply device at the mouth and nose, the oxygen supply device is controlled to execute the oxygen output process to quickly and accurately deliver oxygen to the respiratory tract of the target patient, so as to increase the oxygen flow of his respiratory system and quickly and effectively improve the patient's hypoxia condition.

[0152] When it is detected that the target patient is not wearing the oxygen mask or oxygen delivery head of the oxygen supply device correctly at the mouth and nose, the control device controls the oxygen supply device to start the oxygen output increase process to increase the oxygen content in the space where the patient is placed, thereby increasing the amount of oxygen inhaled by the target patient and improving the patient's hypoxia condition.

[0153] In this embodiment, the transfer system also includes a monitoring device and an oxygen supply device installed in the space where the injured and sick are placed. After querying the first aid measures corresponding to the abnormal physical state, if the first aid measures indicate to perform oxygen supply operation, the monitoring device is used to monitor whether the oxygen supply device is correctly worn at the mouth and nose of the target injured and sick. When it is monitored that the oxygen supply device is correctly worn at the mouth and nose of the target injured and sick, the oxygen supply device is controlled to execute the oxygen output process, so that oxygen can be delivered to the respiratory tract of the target injured and sick quickly and accurately, thereby quickly and effectively improving the hypoxic state of the injured and sick.

[0154] In one embodiment, the transport system further comprises a defibrillator, wherein the main unit of the defibrillator is installed in the patient placement space, and an electrode pad interface is provided on the main unit of the defibrillator, through which the main unit of the defibrillator is detachably connected to the defibrillator electrodes of the defibrillator. The negative pressure fixing device is also used to fix the defibrillator electrodes of the defibrillator to corresponding positions of the patient. Before or during the transport of the target patient, the medical staff or the patient themselves wrap the flexible fixing device around the patient's torso and neck, so that various sensors, electrodes, and chest compression devices are located at corresponding positions of the patient, such as the defibrillator electrodes are fixed to corresponding defibrillation positions. The exhaust device is then opened, the power supply of the negative pressure device is activated, and the negative pressure device is mechanically evacuated to form a negative pressure fixation, thereby fixing various sensors, electrodes, and chest compression devices to corresponding positions of the target patient. The cable of the defibrillator electrodes is then inserted into the electrode pad interface on the main unit of the defibrillator, so that the main unit of the defibrillator is activated for defibrillation when the defibrillation process needs to be executed later.

[0155] After step S30, that is, after the control device queries the first aid measures corresponding to the abnormal physical state, it is further configured to perform the following steps:

[0156] SB50: Determine the control strategy for the defibrillator when first aid measures indicate defibrillation.

[0157] When the target patient's physical condition is determined to be ventricular fibrillation among the abnormal physical conditions, the first aid measure corresponding to the ventricular fibrillation condition is checked and the first aid measure is defibrillation. When the first aid measure indicates defibrillation, indicating that the target patient is in ventricular fibrillation, the control device determines a control strategy for the defibrillator.

[0158] Among them, the control strategy of the defibrillator device can be a pre-established and stored defibrillator control strategy; in other embodiments, the control strategy of the defibrillator device can also be a defibrillator control strategy generated by a pre-trained defibrillator strategy generation model based on the vital sign data of the current target patient, so as to improve the accuracy and safety of the defibrillator control strategy.
