Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] Battlefield first aid and transportation has always been a difficult problem for medical support. Under the conditions of modern war, the injury factors are complex and diverse, and the battlefield environment changes frequently, so it is difficult for medical personnel to rescue the wounded and complete the transportation in wartime.

[0043] The current medical escort equipment mainly relies on stretcher equipment to transport the wounded to a specific location. However, in the prior art, the vital signs of the wounded need to be monitored during the transportation process. Therefore, the medical staff needs to connect the vital sign monitoring equipment to the wounded, place the wounded on the stretcher equipment, hold the vital sign monitoring equipment with both hands, and transport the wounded to a specific location.

[0044] Therefore, the above method is not convenient for transporting the wounded, and wastes the human resources of the medical staff, thereby causing waste of medical resources.

[0045] Therefore, the above method is not convenient for transporting the wounded, and wastes the human resources of the medical staff, thereby causing waste of medical resources. Figure 1 As shown in the drawings, the present application provides a stretcher-based wounded transportation life monitoring and support system. The stretcher-based wounded transportation life monitoring and support system comprises a stretcher device, at least one monitoring device, a fixing device, and an electronic device. The fixing device is detachably installed on the stretcher device, and each monitoring device and each life support device is detachably fixed on the fixing device. Each monitoring device is in communication connection with the electronic device, wherein:

[0046] The stretcher device is used for transporting the wounded;

[0047] The fixing device is used for installing each monitoring device and each life support device on the stretcher device;

[0048] Each monitoring device is used for monitoring the vital signs of the wounded, acquiring vital sign data, displaying the vital sign data, and transmitting the vital sign data to the electronic device;

[0049] An electronic device is configured to receive vital sign data transmitted by each monitoring device and identify each vital sign data. When an abnormality occurs in the vital sign data, the electronic device outputs a prompt information.

[0050] Specifically, the wounded person can lie on a stretcher device. The fixing device is detachably installed on the side supports of the stretcher device. Each monitoring device is detachably fixed on the fixing device, and each monitoring device is connected to the wounded person for monitoring the vital signs of the wounded person, acquiring vital sign data, and displaying the vital sign data. In addition, the monitoring device transmits the monitored vital sign data to the electronic device.

[0051] The monitoring device can include, but is not limited to, an electrocardiograph, a sphygmomanometer, an oxygen saturation monitor, a thermometer, a respiration monitor, a blood glucose meter, and a multi-parameter monitor, etc. The electrocardiograph is used to monitor the electrical activity of the heart, such as heart rate and rhythm.

The thermometer is used to measure body temperature, including oral, armpit, rectal thermometers, etc. The respiration monitor is used to monitor respiratory rate and depth. The blood glucose meter is used to measure blood glucose levels. The multi-parameter monitor is used to monitor multiple vital signs of the human body, such as heart rate, respiratory rate, blood pressure, and oxygen saturation, etc. Common multi-parameter monitors include bedside monitors and portable monitors, etc.

[0052] The life support device can include, but is not limited to, a ventilator, a cardiopulmonary resuscitation device such as a defibrillator, an infusion pump, a nutritional support device such as a nasogastric tube, a gastrostomy tube, etc., a blood purification device such as a dialysis machine, a body temperature regulation device, etc.

[0053] The electronic device receives vital sign data transmitted by each monitoring device. Then, the electronic device identifies each vital sign data, uses specific algorithms and models to analyze and process the collected vital sign data to determine whether these vital sign data are outside the normal range or have other unusual patterns. For example, excessively high or low heart rate, abnormally high or low blood pressure, etc. When the electronic device detects an abnormality in the vital sign data, it outputs a prompt information to alert the user. The prompt information can be presented in various forms, such as sound alarm, vibration, screen display, etc.

[0054] The stretcher-based wounded person transportation life monitoring and support system provided in the embodiments of the present application can detachably install the fixing device on the stretcher device, and detachably fix each monitoring device and each life support device on the fixing device, so as to detachably install the monitoring device and the life support device on the stretcher device, and further solve the problem of lack of effective life monitoring and support means during the transportation of the wounded person on the stretcher. The medical staff does not need to carry equipment to monitor and support the wounded person, so that the human resources of the medical staff are saved. In addition, each monitoring device monitors the vital signs of the wounded person, acquires vital sign data, displays the vital sign data, and transmits the vital sign data to the electronic device, so that the electronic device can receive each vital sign data. The electronic device receives the vital sign data transmitted by each monitoring device, identifies each vital sign data, and outputs prompt information when the vital sign data is abnormal, so as to ensure the accuracy of the output prompt information, and further enable the medical staff to quickly and accurately acquire the vital sign state of the wounded person, without the need for the medical staff to check the vital sign data monitored by the monitoring device in real time, thereby further saving the human resources of the medical staff, and saving the medical resources.

[0055] In an optional embodiment of the present application, as shown in Figure 2 The fixing device includes a telescopic support, a bottom panel and a side panel. One end of the telescopic support is installed below the bottom panel, and the other end of the telescopic support is detachably installed on the stretcher device. The telescopic support can adjust the telescopic length according to the body type of the wounded person to be suitable for each wounded person. The bottom panel and the side panel are connected by a support rod. One end of the support rod is fixed to the side panel, and the other end of the support rod is placed in a groove of the side panel. The angle between the bottom panel and the side panel is adjusted by moving the position of the support rod in the groove of the side panel.

[0056] The bottom panel and the side panel are hingedly connected. The bottom panel is used to place each monitoring device and each life support device, and the side panel is used to fix each monitoring device and each life support device.

[0057] Specifically, the fixing device includes a telescopic support, a bottom panel and a side panel. The number of telescopic supports can be 4 or 6, and the number of telescopic supports is not limited in the embodiments of the present application.

[0058] For each telescopic support, one end of the telescopic support is fixedly installed below the bottom panel, and the other end of the telescopic support is detachably installed on the stretcher device. The telescopic support can be telescoped in the up-down direction to adjust the distance between the bottom panel and the stretcher device.

[0059] Optionally, the other end of the telescopic support can be detachably installed on the two supports of the stretcher device through bolts and nuts.

[0060] In another alternative embodiment of the present application, one end of the telescopic support is mounted under the bottom panel by a hinge. When the fixing device is not needed, the telescopic support can be folded by the hinge so that the telescopic support is in contact with the bottom panel, thereby facilitating the storage of the fixing device. When the fixing device is needed, the telescopic support can be folded by the hinge so that the telescopic support is perpendicular to the bottom panel, thereby facilitating the detachable mounting of the other end of the telescopic support on the stretcher device.

[0061] Specifically, as shown in Figure 2 , the bottom panel and the side panel are connected by a hinge. In addition, the bottom panel and the side panel can also be connected by a support rod, one end of which is fixed on the side panel and the other end of which is placed in the groove of the side panel. The angle between the bottom panel and the side panel can be adjusted by moving the position of the support rod in the groove of the side panel.

[0062] In an alternative embodiment, as shown in Figure 2 , the bottom panel and the side panel include a plurality of fixing holes, each of which is used to fix each monitoring device and each life support device.

[0063] Specifically, the fixing bolts provided under each monitoring device can pass through the fixing holes in the bottom panel, and then the bolts are tightened with nuts, thereby fixing each monitoring device on the bottom panel.

[0064] The fixing bolts provided behind each monitoring device can pass through the fixing holes in the side panel, and then the bolts are tightened with nuts, thereby fixing each monitoring device on the side panel.

[0065] In an alternative embodiment, the bottom panel can be folded, if the number of monitoring devices and / or life support devices is greater than a preset data quantity threshold, the bottom panel is laid flat; if the number of monitoring devices and / or life support devices is less than or equal to the preset data quantity threshold, the bottom panel is folded.

[0066] Specifically, the bottom panel can be divided into a plurality of sub-bottom panels, each of which is connected by a hinge, and each of which can be folded into multiple layers or laid flat into one layer. It should be noted that when each sub-bottom panel is folded into multiple layers, the fixing holes in each sub-bottom panel overlap each other, thereby fixing each monitoring device and each life support device through the overlapping fixing holes.

[0067] If the number of monitoring devices and / or life support devices is greater than a preset data quantity threshold, the bottom panel is laid flat, thereby fixing a plurality of monitoring devices. If the number of monitoring devices and / or life support devices is less than or equal to the preset data quantity threshold, the bottom panel is folded, thereby reducing the space occupied by the bottom panel.

[0068] The stretcher-based wounded transport life monitoring and support system provided by the embodiments of the present application can realize the telescopic support to adjust the telescopic length according to the size of the wounded, so as to be applicable to various wounded and improve the universal applicability of the stretcher-based wounded transport life monitoring and support system. In addition, the bottom panel and the side panel are hingedly connected, facilitating the storage of the fixing device. The bottom panel is used to place various monitoring devices and various life support devices, and the side panel is used to fix various monitoring devices and various life support devices, so that the monitoring devices and the life support devices can be detachably mounted on the stretcher device, thereby solving the problem of lack of effective life monitoring and support means for the wounded in the stretcher during transport. Therefore, the human resources of medical staff are saved, and the medical resources are saved.

[0069] Among them, the bottom panel and the side panel include a plurality of fixing holes, and each fixing hole is used to fix each monitoring device and each life support device, so that each monitoring device can be firmly mounted on the fixing device, and the problem of unstable installation of the monitoring device on the stretcher device is avoided.

[0070] In addition, the bottom panel can be folded. If the number of monitoring devices and / or life support devices is greater than a preset data amount threshold, the bottom panel is laid flat; if the number of monitoring devices and / or life support devices is less than or equal to the preset data amount threshold, the bottom panel is folded, so that a plurality of monitoring devices can be mounted on the fixing device.

[0071] In an optional embodiment of the present application, as shown in Figure 3 The electronic device can include the following steps:

[0072] Step S201, the electronic device performs data fusion processing on each vital sign data to generate fused vital sign data.

[0073] Specifically, the above step S201 can include the following steps:

[0074] Step S2011, the electronic device obtains weight information corresponding to each monitoring device.

[0075] The weight information is related to the accuracy of the monitoring device corresponding to the weight information and the importance of the vital sign data monitored by the monitoring device.

[0076] Specifically, the electronic device can receive weight information corresponding to each monitoring device input by the user, receive weight information corresponding to each monitoring device sent by other devices, and determine weight information corresponding to each monitoring device according to attribute information corresponding to each monitoring device. The embodiments of the present application do not make specific limitations on the way the electronic device obtains the weight information corresponding to each monitoring device.

[0077] In step S2012, the electronic device fuses the vital sign data based on a preset fusion algorithm according to the weight information corresponding to each monitoring device, to generate fused vital sign data.

[0078] Specifically, step S2012 can include the following steps:

[0079] In step a1, feature extraction is performed on the vital sign data according to the data format corresponding to each vital sign data, to generate initial features corresponding to each vital sign data.

[0080] Specifically, the electronic device can identify each vital sign data and determine the data format corresponding to each vital sign data. Then, according to the data format corresponding to each vital sign data, a preset feature extraction method is determined, and feature extraction is performed on the vital sign data based on the preset feature extraction method, to generate initial features corresponding to each vital sign data.

[0081] For example, for image data, convolutional neural network (CNN) can be used for feature extraction; for time series data, recurrent neural network (RNN) or long short-term memory network (LSTM) can be used for feature extraction.

[0082] In step a2, the initial features corresponding to each vital sign data are multiplied by the corresponding weight information, to generate target features corresponding to each vital sign data.

[0083] Specifically, the electronic device can multiply the initial features of each vital sign data with the corresponding weight. Then, the result of the multiplication is taken as the target feature of the vital sign data.

[0084] For example, assuming that there are three vital sign data: body temperature, heart rate and blood pressure, their initial features are T, H and B respectively, and the corresponding weights are w_T, w_H and w_B respectively. Then the target features can be generated in the following way: target feature = w_T*T + w_H*H + w_B*B In this way, each vital sign data has a corresponding target feature, which takes into account the initial features and weight information.

[0085] In step a3, the target features are fused based on the Kalman filter fusion algorithm, to generate fused vital sign data.

[0086] Specifically, the electronic device can initialize parameters of the Kalman filter fusion algorithm, including a state vector, a covariance matrix, a measurement noise covariance matrix, and the like. Then, according to the state estimation value at the last moment and the model parameters, the state estimation value at the current moment is predicted. Then, according to the measurement value at the current moment and the predicted value, the state estimation value and the covariance matrix are updated. Finally, the state estimation values of the multiple target features are fused to obtain the fused vital sign data.

[0087] In step S202, the electronic device inputs the fused vital sign data into a preset early warning model to output a vital sign stability level corresponding to the wounded person.

[0088] Specifically, the stretcher-based wounded person transfer life monitoring and support system further comprises a camera assembly in communication with the electronic device. The camera assembly is configured to capture images of the wounded person, generate wounded person images, and transmit the wounded person images to the electronic device. The step S202 of inputting the fused vital sign data into the preset early warning model to output the vital sign stability level corresponding to the wounded person can include the following steps:

[0089] In step S2021, the electronic device identifies the wounded person image to determine the wounded position image corresponding to the wounded person.

[0090] Specifically, the electronic device pre-processes the wounded person image, such as denoising, contrast enhancement, cropping, and the like, to improve the image quality and facilitate subsequent processing. Then, the pre-processed wounded person image is input into a wounded position image recognition model, and the wounded position image recognition model extracts features from the pre-processed wounded person image to output the wounded position image corresponding to the wounded person.

[0091] In step S2022, the electronic device inputs the fused vital sign data and the wounded position image corresponding to the wounded person into the preset early warning model to output the vital sign stability level corresponding to the wounded person.

[0092] Specifically, the step S2022 can include the following steps:

[0093] In step b1, the electronic device identifies the wounded person image to determine the body type and / or age and / or gender corresponding to the wounded person.

[0094] Specifically, the electronic device can use a target detection algorithm to identify the wounded person image and determine a target region of interest from the wounded person image.

[0095] The target detection algorithm can be a model based on manual features, such as a DPM (Deformable Parts Model), or a model based on a convolutional neural network, such as a YOLO (You Only Look Once) detector, an R-CNN (Region-based Convolutional Neural Networks) model, an SSD (Single Shot MultiBox) detector, and a Mask R-CNN (Mask Region-based Convolutional Neural Networks) model, and the like. The embodiments of the present application do not make specific limitations on the target detection algorithm.

[0096] Then, the electronic device can identify the target region of interest using a face recognition algorithm. The face recognition algorithm can extract features from the target region of interest to obtain facial features, and determine a wounded person's face image based on the facial features.

[0097] Specifically, the electronic device can identify the target region of interest using a body recognition algorithm. The body recognition algorithm can extract features from the target region of interest to obtain body features, and determine a wounded person's body image based on the body features.

[0098] Then, the electronic device inputs the wounded person's face image to an age recognition model and a gender recognition model. The age recognition model extracts features from the wounded person's face image, such as facial contour features, facial wrinkle features, facial texture features, and facial skin color features, and then outputs age information of the wounded person based on the extracted features.

[0099] The gender recognition model extracts features from the wounded person's face image, and outputs gender information of the wounded person based on the extracted features.

[0100] The age recognition model and the gender recognition model can be a model based on manual features, such as a DPM (Deformable Parts Model), and can also be a model based on a convolutional neural network, such as a YOLO (You Only Look Once) detector, an R-CNN (Region-based Convolutional Neural Networks) model, an SSD (Single Shot MultiBox) detector, and a Mask R-CNN (Mask Region-based Convolutional Neural Networks) model, etc. The embodiments of the present application do not make specific limitations on the age recognition model and the gender recognition model.

[0101] In addition, the electronic device inputs the body image of the wounded person into the body recognition model to determine the body type of the wounded person.

[0102] Step b2, the electronic device determines the target preset warning model from the plurality of candidate preset warning models according to the body type and / or age and / or gender corresponding to the wounded person.

[0103] Specifically, the electronic device can determine the target preset warning model from the plurality of candidate preset warning models according to the body type and / or age and / or gender corresponding to the wounded person.

[0104] Step b3, the electronic device inputs the fusion vital sign data and the wounded position image corresponding to the wounded person into the target preset warning model, and outputs the vital sign stability level corresponding to the wounded person.

[0105] Specifically, the above step b3 “inputs the fusion vital sign data and the wounded position image corresponding to the wounded person into the target preset warning model, and outputs the vital sign stability level corresponding to the wounded person” can include the following steps:

[0106] Step b31, the electronic device inputs the fusion vital sign data and the wounded position image corresponding to the wounded person into the target preset warning model.

[0107] Specifically, the electronic device inputs the fusion vital sign data and the wounded position image corresponding to the wounded person into the target preset warning model.

[0108] Step b32, the target preset warning model maps the wounded position image into a three-dimensional image feature vector based on an image coding method.

[0109] Specifically, the electronic device can pre-process the wounded position image, such as cropping, resizing, graying, etc., to ensure the consistency and processability of the data. Then, the electronic device extracts relevant features from the pre-processed image using appropriate feature extraction algorithms. These features can be descriptors based on shape, texture, color, etc. Then, the electronic device maps the extracted features to a three-dimensional image feature vector using a preset image encoding method. The preset image encoding method can include a convolutional neural network (CNN) based on deep learning, a method based on traditional machine learning such as principal component analysis (PCA), etc.

[0110] Step b33, feature extraction is performed on the image feature vector and the fused vital sign data, and a stable level of vital signs corresponding to the wounded person is output based on the extracted features.

[0111] Specifically, the electronic device can perform feature extraction on the image feature vector and the fused vital sign data, and output a stable level of vital signs corresponding to the wounded person based on the extracted features.

[0112] The stable level of vital signs can include a first level, a second level, and a third level. The first level represents that each vital sign data of the wounded person is within the normal range, the second level represents that at least one vital sign data of the wounded person is outside the normal range but within a preset range, and the third level represents that at least one vital sign data of the wounded person is outside the preset range. For example, the normal value range of blood pressure is diastolic pressure 60-90 mmHg and systolic pressure 90-130 mmHg; the preset range is diastolic pressure 90-110 mmHg and systolic pressure 130-180 mmHg; and the range outside the preset range is diastolic pressure <60 mmHg or >110 mmHg and systolic pressure <90 mmHg or >180 mmHg.

[0113] Step S203, the electronic device determines that the vital sign data is abnormal when the stable level of vital signs is greater than or equal to a preset level, and outputs a prompt information.

[0114] Specifically, the electronic device can receive a preset level input by a user, and then compare the stable level of vital signs with the preset level. When the stable level of vital signs is greater than or equal to the preset level, it is determined that the vital sign data is abnormal, and a prompt information is output.

[0115] The preset level can be the second level. When the stable level of vital signs is greater than or equal to the second level, it is determined that the vital sign data is abnormal, and a prompt information is output.

The electronic device extracts features from the vital sign data according to the data format corresponding to each vital sign data, generates initial features corresponding to each vital sign data, ensuring the accuracy of the generated initial features corresponding to each vital sign data. The initial features corresponding to each vital sign data are multiplied by the corresponding weight information to generate target features corresponding to each vital sign data, ensuring the accuracy of the generated target features corresponding to each vital sign data. Based on the Kalman filtering fusion algorithm, the target features are fused to generate fused vital sign data, ensuring the accuracy of the generated fused vital sign data. Further, the generated fused vital sign data can fully reflect the vital signs of the wounded person.

[0117] Then, the camera assembly photographs the wounded person, generates a wounded person image, and transmits the wounded person image to the electronic device, so that the electronic device can receive the wounded person image. The electronic device identifies the wounded person image to determine the wounded position image corresponding to the wounded person, ensuring the accuracy of the determined wounded position image corresponding to the wounded person. The electronic device inputs the fused vital sign data and the wounded position image corresponding to the wounded person into a target preset warning model, the target preset warning model maps the wounded position image into a three-dimensional image feature vector based on an image coding method, ensuring the accuracy of the generated image feature vector. The image feature vector and the fused vital sign data are extracted, and the vital sign stability level corresponding to the wounded person is output based on the extracted features, ensuring the accuracy of the generated vital sign stability level corresponding to the wounded person. Further, medical personnel can quickly and accurately obtain the vital sign state of the wounded person, without the need for medical personnel to view the vital sign data monitored by the monitoring device in real time, thereby further saving the human resources of medical personnel, thereby saving medical resources.
