Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a monitoring device and a method for prompting monitoring risks thereof. Background Art

[0002] Pressure sores (pressure injuries, bedsores) refer to tissue ulceration and necrosis caused by persistent ischemia, hypoxia, and malnutrition due to long-term pressure (pressure, shear force, friction) on local tissues. In critical care departments such as ICU and CCU, patients are in critical condition, have limited mobility, are bedridden for a long time, have unclear consciousness, circulatory disorders, and malnutrition. The incidence of pressure sores is higher, which seriously affects the quality of life of patients, prolongs the length of hospital stay, and increases the workload and medical costs of critical care staff.

[0003] Pressure sores can occur anywhere on the body, but are more common on bony or cartilaginous areas, such as the occipital area, hip, scapula, spine, sacrum, elbow, knee, ankle, etc. The clinical guidelines divide pressure sores into four stages: the first stage is the congestion and ruddy stage, with superficial redness that does not subside; the second stage is the inflammatory infiltration stage, with the dermis disappearing and manifesting as a shallow open ulcer; the third stage is the shallow ulcer stage, with epidermal damage, ulcers forming and extending to the subcutaneous tissue layer; the fourth stage is the necrotic ulcer stage, which invades the subcutaneous layer, muscle layer and bone surface. Pressure sores are the deepest and difficult to heal. It is particularly important to actively prevent the occurrence of pressure sores in the early stage and pay close attention to the development and treatment of pressure sores in the later stage.

[0004] In clinical practice, wound dressings are generally used to treat pressure sores. Different treatment strategies or dressing types are used for pressure sores at different stages, and drug treatment is mostly a reactive treatment based on the patient's sore surface. In addition, mechanical treatment is also a common method, such as special air mattresses, water mattresses, special mattresses, pads or other support devices, which are designed to reduce the pressure on the patient's bony prominences.

[0005] Clinical studies generally believe that pressure relief is the best strategy for preventing pressure sores. Usually, regular turning and nursing operations are performed to change the patient's bed position and relieve the pressure on the support surface to prevent skin pressure accumulation, which leads to loss of circulation and pressure sores. Many clinical institutions have implemented strict pressure sore assessment and prevention mechanisms, such as regular pressure sore risk assessments for patients, daily key area inspections, and regular turning and nursing operations for patients. However, due to the busy medical and nursing work in clinical practice, and the different levels of pressure sores for different patients, the frequency requirements for turning and nursing operations are different. Nurses often forget to turn over, and sometimes it is difficult to judge the appropriate time for turning over. These lead to poor pressure sore protection for patients and low efficiency.

[0045] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0046] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0047] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0048] In the existing technology, the use of video to assess the patient's risk of pressure sores is mostly based on the judgment of the patient's body position. For example, when the duration of the patient maintaining the same body position exceeds a threshold, the risk of pressure sores is prompted, or when the time difference between the patient's two typical static body positions exceeds a threshold, the risk is prompted, or when the time since the last significant change in body position exceeds a threshold, the risk is prompted, etc. This type of technology is based on judging the overall position change of the patient to a certain extent, and cannot accurately prompt the nurse to focus on the patient's body part for pressure sore risk, and cannot accurately reflect the risks of different body parts of the patient.

[0049] The technical solution proposed in the present invention emphasizes based on refined video analysis. In addition to judging the overall posture of the patient, it also judges the movement of each body part of the patient, and reflects the risk of fine parts of the patient's pressure sore based on the duration of each part not moving, providing a reference for nurses to perform more refined and personalized pressure sore care operations (such as turning over, skin care / cleaning, air cushion use, etc.). This is described in detail below through some embodiments.

[0050] like Figure 1 As shown, the present invention provides a monitoring risk prompting method, which provides a risk prompt of a patient's long-term immobility by monitoring the patient's local movement, thereby improving the effect of pressure sore protection for the patient, and includes the following steps:

[0051] Step 1, obtain the patient's image information. The image information includes the patient's image, and may also include images of the background such as the bed. It may be a video of the patient, infrared data, or depth data, etc. For example, a camera may be used to capture a video of the patient and his or her bed. For another example, an infrared sensor may be used to collect infrared data of the patient and his or her bed. For another example, a 3D depth sensor may be used to collect depth data of the patient and his or her bed. This embodiment is illustrated using a video of the patient as an example. The camera has a wide viewing angle and can even capture videos of multiple patients at the same time. In this embodiment, the patient's image information obtained in step 1 is real-time, so that the patient can be monitored in real time through subsequent steps.

[0052] Step 2: Detect the movement of one or more parts of the patient based on the image information. The movement of a certain part of the patient can be detected. This embodiment takes into account that multiple parts of the pressure sore scene are prone to poor skin blood flow, so it is described by taking the detection of multiple parts as an example. These parts can be multiple of the head, trunk (such as chest, buttocks, etc.), upper limbs (left, right, elbows, etc.), and lower limbs (left, right, thighs, calves, knees, feet, etc.).

[0053] The motion of the part may include the motion amplitude, motion duration and motion frequency of the part. In this embodiment, the image information of the patient is acquired in real time and continuously, so the motion of each part detected in step 2 is related to time, that is, its motion amplitude, motion duration and motion frequency all have time information, such as in a certain time period, its motion amplitude, motion duration and motion frequency are 0 (no motion occurs), that is, when the part does not move, the motion amplitude, motion duration and motion frequency are all 0; and in another time period, its motion amplitude, motion duration and motion frequency are not 0 (motion occurs). Each part can be identified from the image information first. For example, the traditional image processing segmentation technology can be used to identify the various parts of the patient from the patient's image information. Specifically, each part can be identified from the image frame of the patient's video by target detection, target segmentation and other technologies; the patient's video can also be processed by computer vision (CV technology) based on deep learning of AI to identify each part. The patient may be covered with a quilt. In this case, the head can be identified from the image information first, and the general outline of the body can be identified according to the concave and convex situation of the quilt, and then the position of each part can be predicted according to the general outline of the head and body. Then, motion analysis is performed on each part to obtain the motion status of each part. For example, the motion of the part can be detected by using the frame difference method to obtain the difference between each frame image of the part in the video, and then the motion status of the part can be obtained according to the difference between the part images and the time corresponding to each frame image; for another example, the change amplitude of the key points of the part in different image frames can be detected to obtain the motion status of the part.

[0054] The patient's overall movement can also be detected based on the image information. The patient's overall movement can also include the patient's overall movement amplitude, movement duration, and movement frequency. The patient can also be identified from the image information. For example, the patient can be identified from the patient's image information using traditional image processing segmentation technology. Specifically, the patient can be identified from the image frame of the patient's video using target detection, target segmentation, and other technologies. The patient's video can also be processed based on AI deep learning computer vision (CV technology) to identify the patient as a whole. The patient may be covered with a quilt. In this case, the head can also be identified from the image information first, and the general outline of the body can be identified based on the concave and convex conditions of the quilt. Then, the position of the patient in the image can be obtained by combining the general outline of the head and body. Then, the patient's overall movement can be analyzed to obtain the patient's overall movement. For example, the frame difference method can be used to detect the overall movement of the patient, and the difference between the frames of the patient in the video can be obtained. The patient's overall movement can be obtained based on the difference between the images and the time corresponding to each frame. For example, the change amplitude of the key points of the patient in different image frames can be detected to obtain the patient's overall movement.

[0055] In this embodiment, the overall movement condition of the patient is obtained according to the movement condition of one or more parts of the patient. There are many specific implementation methods, and three of them are introduced below.

[0056] One way is to perform a weighted summation of the movement conditions of each part to obtain the patient's overall movement condition, such as performing a weighted summation of the movement amplitudes of each part to obtain the patient's overall movement amplitude; performing a weighted summation of the movement durations of each part to obtain the patient's overall movement duration; performing a weighted summation of the movement frequencies of each part to obtain the patient's overall movement frequency, etc.

[0057] Another way is to use the movement of the part with the largest range of motion as the overall movement. Exercise can effectively prevent the occurrence of pressure sores, so the movement of the part with the largest range of motion can well reflect the patient's overall movement.

[0058] Another way is to use the movement conditions of one or more preset parts as the overall movement conditions. For example, if the trunk is prone to pressure sores, the movement conditions of the trunk can be used as the overall movement conditions.

[0059] Step 3, judge whether the movement of each part meets the preset requirements according to the movement of each part. If the movement of a part meets the preset requirements, it is determined that the part has made effective movement. If it does not meet the preset requirements, it is determined that the part has not made effective movement. No movement of a part also means no effective movement. For pressure sore monitoring, the movement of the patient does not necessarily mean that it is helpful for pressure sore care. Exercise that meets certain requirements is helpful for pressure sore care. The present invention screens the movement of each part according to preset requirements, so that risk warnings can be accurately provided.

[0060] The overall posture of the patient can also be detected according to the image information, that is, the patient's body position, such as supine position, lateral position or attached position, can be detected according to the image information. Even if the patient is covered with a quilt, the convexity of the head and the quilt can be identified from the image information, and then the patient's body position can be obtained by combining the convexity of the head and the quilt. If the quilt bulge is relatively large and the head is tilted to one side, the patient is determined to be in the lateral position; if the quilt bulge is relatively small and the face is facing up or down, the patient is determined to be in the supine position or attached position. According to the overall posture of the patient and the movement of each part, it can be judged whether the movement of each part meets the preset requirements. The pressure of each part is different under different overall postures, and some parts are not even compressed. Therefore, judging the movement of the part in combination with the overall posture can obtain the judgment result more accurately and quickly. For example, according to the overall posture of the patient, multiple parts of the body under pressure in the posture can be determined; and then the movement of each part of the body under pressure in the posture can be judged whether it meets the preset requirements. It is equivalent to screening each part using the overall posture of the patient, thereby improving the processing speed. In the current overall posture, the parts of the body that are not under pressure have no risk of pressure sores. In other words, for the parts of the body that are not under pressure in the current overall posture, regardless of their movement, even if there is no movement, they are considered to meet the preset requirements. For each part of the body that is under pressure in this posture, it is necessary to determine whether its movement meets the preset requirements.

[0061] In this embodiment, the pressure-bearing parts corresponding to three postures are given as examples for description.

[0062] When the patient is in a supine position, the multiple parts of the body that are under pressure include the headrest, shoulder blades, ischial tuberosity, sacrum and calcaneus. In other words, when the patient lies flat, the headrest, shoulder blades, ischial tuberosity, sacrum and calcaneus are under pressure. If the patient does not exercise effectively for a long time, the risk of pressure sores is likely to occur, and risk monitoring is required.

[0063] When the patient's overall posture is in a prone position, the multiple parts of the body that are under pressure in this posture include: forehead, shoulders, frontal spine, knees and feet. In other words, when the patient lies prone, the forehead, shoulders, frontal spine, knees and feet are under pressure. If the patient does not exercise effectively for a long time, the risk of pressure sores is likely to occur, and risk monitoring is required.

[0064] When the patient's overall posture is side-lying, the multiple parts of the body that are under pressure in this posture include: shoulders, frontal spines, knee joints and feet. In other words, when the patient lies on his side, the shoulders, frontal spines, knee joints and feet are under pressure. If the patient does not exercise effectively for a long time, it is easy to have the risk of pressure sores, and risk monitoring is required.

[0065] The preset requirements can be set as needed, and are basically set around one or more of the movement amplitude, movement duration and movement frequency. The preset requirements can include one or more of the following three conditions:

[0066] Condition 1: the movement amplitude exceeds the preset amplitude threshold;

[0067] Condition 2: the duration of the exercise exceeds the preset time;

[0068] Condition 3: the movement frequency exceeds a preset frequency threshold.

[0069] Therefore, according to the movement of each part, it is judged whether the movement of each part meets the preset requirements. Specifically, the following methods can be used:

[0070] If the motion condition only includes the motion amplitude or only condition 1 is used as the preset requirement, it can be judged whether the motion amplitude of each part exceeds the preset amplitude threshold. The motion condition of the part whose motion amplitude exceeds the preset amplitude threshold meets the preset requirement; on the contrary, the motion condition of the part whose motion amplitude does not exceed the preset amplitude threshold does not meet the preset requirement.

[0071] If the motion condition only includes the motion duration or only condition 2 is used as the preset requirement, it can be judged whether the motion duration of each part exceeds the preset duration. The motion condition of the part whose motion duration exceeds the preset duration meets the preset requirement; on the contrary, the motion condition of the part whose motion duration does not exceed the preset duration does not meet the preset requirement.

[0072] If the motion condition only includes the motion frequency or only condition 3 is used as the preset requirement, it can be judged whether the motion frequency of each part exceeds the preset frequency threshold. The motion condition of the part whose motion frequency exceeds the preset frequency threshold meets the preset requirement; on the contrary, the motion condition of the part whose motion frequency does not exceed the preset frequency threshold does not meet the preset requirement.

[0073] Each part may be a part of the body that is under pressure in the current overall posture, so that only the pressure-under-pressure part is judged, which is conducive to saving the amount of calculation and processing.

[0074] In this embodiment, the preset requirements include the above three conditions. Only when the three conditions are met at the same time, the exercise situation is considered to meet the preset requirements. Otherwise, the exercise situation is considered not to meet the preset requirements. More conditions are more likely to trigger the subsequent provision of risk warning information, so that the patient can be monitored more timely.

[0075] From the above conditions, it can be seen that for the time period when the movement amplitude, movement duration and movement frequency are 0, it must not meet the preset requirements, that is, no effective movement is done. Therefore, only for the parts of the body that are under pressure, it is possible to judge whether the movement conditions of the time periods in which the movement conditions are not 0 meet the preset requirements. If the movement conditions of a part in this time period meet the preset requirements, it is determined that the part has undergone effective movement in this time period, and the effective movement of the part can be recorded as an effective movement event. The effective movement event is associated with the time period in which the effective movement occurs; if the movement conditions of the part in this time period do not meet the preset requirements, it is determined that the part has not undergone effective movement in this time period. For the parts of the body that are not under pressure in the current overall posture, they are similar to the parts that have undergone effective movement, and the risk of pressure sores is low. Therefore, the time period when the part is not under pressure can also be determined as an effective movement event.

[0076] In this embodiment, it is also determined whether the patient's overall movement conditions meet the preset requirements based on the patient's overall movement conditions. If the patient's overall movement conditions meet the preset requirements, it is determined that the patient as a whole has done effective exercise. If they do not meet the preset requirements, it is determined that the patient as a whole has not done effective exercise. The patient's overall no movement also belongs to no effective exercise. The preset requirements of the patient as a whole can be the same as the preset requirements of the above-mentioned parts. The process of judging whether the patient's overall movement conditions meet the preset requirements is also the same as the process of judging whether the movement conditions of the parts meet the preset requirements. The only difference is that one is the patient as a whole and the other is the patient's parts, so it will not be repeated.

[0077] Similarly, the patient's overall movement amplitude, movement duration and movement frequency are 0 in the time period, and no effective movement is performed. Therefore, it is only possible to determine whether the patient's overall movement status in the time period when the patient's overall movement status is not 0 meets the preset requirements. If the movement status in the time period meets the preset requirements, it is determined that the patient as a whole has performed effective movement in the time period, and the effective movement performed by the patient as a whole can be recorded as an effective movement event. The effective movement event is associated with the time period in which the effective movement occurs; if the patient's overall movement status in the time period does not meet the preset requirements, it is determined that the patient as a whole has not performed effective movement in the time period.

[0078] Step 4: For a target part whose motion does not meet the preset requirements within the preset first time threshold, the risk warning information corresponding to the target part is displayed on the display interface. Figure 2 and Figure 3 Area A in the diagram is a risk warning message. The risk warning message is mainly used to remind the user that the target part has not made any effective movement within at least the first time threshold. The usual application scenario is to remind the user that the target part has a risk of pressure sores or needs to be cared for by the target part. In other words, if there is no effective movement event within the first time threshold, it means that the part has no movement within the first time threshold or the movement does not meet the preset requirements, which will accumulate the risk of pressure sores. Therefore, the risk warning information corresponding to the part is displayed on the display interface. When medical staff see the risk warning information, they can perform pressure sore care operations on the part, such as turning over, skin care / cleaning, using air cushions, etc. It can be seen that since the present invention realizes the monitoring of the pressure sore risk of various local parts of the patient, it can reflect the risk of pressure sores in the fine parts of the patient, so that nurses can perform more refined and personalized pressure sore nursing operations. For example, some patients are heavy, and only the risk warning information of individual parts (target parts) is displayed. The nurse can take measures only for the individual parts, and there is no need to turn the patient over as a whole. It is also not easy to have the problem of monitoring cables falling off due to turning over. It can be seen that the present invention greatly improves the pressure sore protection effect for patients.

[0079] Similarly, if the patient's overall movement within the preset second time threshold does not meet the preset requirements, the risk warning information corresponding to the patient as a whole is displayed on the display interface, so that medical staff can combine the overall and local risk warnings to better understand the risks of the patient's long-term immobility. The second time threshold can be the same as the first time threshold, of course, it can also be different. The first time threshold and / or the second time threshold can be preset by the system, or it can be determined based on the user's setting operation. This embodiment is described with the latter as an example. The method provided by the present invention can be applied to monitoring equipment (such as a central station, a monitor, a medical monitoring handheld terminal, etc.), and the above-mentioned display interface can be the display interface of the display of the monitoring equipment. The user can perform setting operations on the display interface to determine the first time threshold and / or the second time threshold, for example, it can be set to 2 hours.

[0080] In some embodiments, each part corresponds to its own first time threshold; the first time thresholds of various parts are not exactly the same. In other words, considering that different parts may be subjected to different pressures under the same posture, a corresponding first time threshold can be set for each part separately, so that the risk of pressure sores can be more accurately and targeted.

[0081] The first time threshold and / or the second time threshold can also be automatically adjusted according to the patient's condition. For example, case information reflecting the patient's condition is obtained, and the first time threshold and / or the second time threshold is determined according to the case information. Among them, the more serious the patient's condition reflected by the case information, the smaller the first time threshold and / or the second time threshold, and the milder the patient's condition reflected by the case information, the larger the first time threshold and / or the second time threshold. As the patient's condition improves and the patient's activities increase, the need for pressure sore prevention becomes less and less. Through this method of automatically adjusting the time threshold, not only the adaptive adjustment of the time threshold is achieved with a high degree of automation, but also the accuracy of the risk warning information is improved to avoid meaningless reminders in the later stage.

[0082] Case information may include at least one of Braden score, perfusion status, nutritional status and personal information. For patients who have been bedridden for a long time, medical staff usually use the Braden score table to assess the risk of pressure sores in patients, thereby obtaining a Braden score. The Braden score is usually stored in the hospital's EMR system (computerized medical record system) or CIS system (clinical information system). The patient's perfusion status such as PI value, body temperature, pulse pressure difference, etc., as well as nutritional status and personal information (such as age, medical history, length of hospitalization) are also usually stored in the EMR system or CIS system, so the patient's case information can be obtained from the EMR system or CIS system.

[0083] Environmental humidity also has a certain impact on the formation of pressure sores, so the environmental humidity can also be obtained, and then the first time threshold and / or the second time threshold are determined according to the environmental humidity; wherein, the greater the environmental humidity, the smaller the first time threshold and / or the second time threshold, and conversely, the smaller the environmental humidity, the larger the first time threshold and / or the second time threshold. Combining case information and environmental humidity to jointly determine the time threshold can provide more accurate pressure sore risk warnings.

[0084] After determining the target part with risk, the target part can be prompted in the form of text or schematic diagram on the display interface, so that medical staff can quickly take nursing measures for the patient based on the target part and its risk warning information.

[0085] The method provided by the present invention can be applied to monitoring equipment. Figure 2-4 These are different display interfaces of monitoring equipment. When the monitoring equipment is a bedside monitor or a medical monitoring handheld terminal (PDA), its display interface is as follows: Figure 2As shown in FIG. 1 , the monitoring data of multiple vital sign parameters of the patient are displayed. The display interface is actually a detailed interface of the patient's vital sign parameters. Whether it is the risk warning information of the target part or the risk warning information of the patient as a whole, it can be displayed in various forms on the display interface. For example, the risk warning information can be displayed in the form of text on the display interface. In this embodiment, Figure 2 As shown, the risk warning information is displayed on the display interface in the form of icon A. Of course, in some embodiments, it can also be displayed on the display interface in the form of icons and text. Figure 2 As shown, the icon A of the risk warning information of the target part not only has a schematic diagram of the patient lying in bed, but also has the duration of no effective exercise of the target part (that is, the duration between the current moment and the last time of effective exercise). The icon of the patient's overall risk warning information can also have a schematic diagram of the patient lying in bed, and also has the duration of no effective exercise of the patient as a whole. The icons of each risk warning information can be displayed on the display interface; of course, considering the limited space of the display interface, when there are multiple risk warning information, only the icon with the longest duration of no effective exercise can be displayed on the display interface. After the medical staff selects the icon, all the currently existing risk warning information will be displayed.

[0086] When the monitoring device is a central station, its display interface is as follows: Figure 3 As shown, an overview of the vital sign parameters of multiple patients is displayed, that is, an overview of some vital sign parameters of multiple patients is displayed in different regions according to different patients or different beds, such as Figure 3 An overview of some vital sign parameters of patients in beds 01-04 is displayed in the display interface; this display interface can be called an overview interface. This makes it easier for medical staff to monitor multiple patients at the same time. Whether it is the risk warning information of the target part or the risk warning information of the patient as a whole, it can be displayed in various forms on the display interface. For example, the risk warning information can be displayed in the form of text on the display interface. In this embodiment, Figure 3 As shown, the risk warning information is displayed on the display interface in the form of icon A. Of course, in some embodiments, it can also be displayed on the display interface in the form of icons and text. Figure 3 The content and display method of the icon A of the medium risk warning information are the same as Figure 2 After the user selects the area displaying the overview of some of the patient's vital signs parameters, or after the user selects icon A on the overview interface, it is equivalent to selecting the patient, and then a new display interface (such as Figure 4 The original overview interface is reduced and displayed on one side of the screen (new display interface), and the detailed interface of the vital sign parameters of the selected patient is displayed on the other side of the screen. The detailed interface can be combined with the display interface of the bedside monitor ( Figure 2 ). Users can see the detailed vital sign parameters of the selected patient on the details interface, and the risk warning information of the target part of the selected patient and the overall risk warning information of the patient can continue to be displayed on the details interface. Figure 2 The embodiment of the bedside monitor shown is not described in detail here.

[0087] The display interface of the above-mentioned monitoring device will pop up a patient status pop-up window C when an alarm message of the patient's vital signs appears. The patient status pop-up window C displays the monitoring data of multiple vital sign parameters associated with the alarm message. For example, the alarm information of the respiratory system is associated with vital sign parameters related to the respiratory system, such as heart rate HR, blood oxygen saturation, respiratory rate RR, etc.; the alarm information of the circulatory perfusion system is associated with vital sign parameters related to the circulatory perfusion system, such as blood oxygen saturation, qSOFA score, etc. This makes it convenient for medical staff to comprehensively evaluate the patient's risk reflected by the alarm information. If there is currently risk warning information for the target area or the patient as a whole, the risk warning information can also be displayed in the patient status pop-up window C, which is convenient for medical staff to assess the risk based on the patient's external condition.

[0088] When the risk warning information is displayed on each of the above display interfaces, or after the risk warning information is selected, the patient's overall posture can also be displayed. After the medical staff knows the patient's overall posture (position), they can predict the potential parts of the patient that have not moved for a long time, and then combine the risk warning information of the target part to double-verify the risk. Even if the determined target part is missing, the medical staff can take care of the missing parts through their own experience and knowledge, thereby greatly reducing the damage caused by the patient's long-term immobility. The overall posture of the display interface can be presented in a variety of ways. For example, the name of the patient's overall posture can be displayed on the display interface, a schematic diagram of the patient's overall posture can also be displayed, and the patient's image information can also be displayed. The medical staff can see the patient's overall posture from the image information. In this embodiment, displaying the patient's overall posture is illustrated by taking the display of the patient's image information as an example.

[0089] In this embodiment, Figure 2-4When icon A is displayed on the display interface in the video window, or after icon A is selected by the user, video window B is displayed on the display interface. Video window B is used to display the patient's image information, thereby presenting the patient's overall posture. The patient's image information displayed in video window B can be a video of the patient, a picture in the video, or multiple pictures at different times in the video. That is, video window B can display the patient's video, and the user can operate video window B to play the patient's video, and can review the patient's previous bed rest state, so that medical staff can judge how to turn the patient over at present. Video window B can also display a picture in the video. In this embodiment, video window B displays multiple pictures at different times in the video, and the intervals between two adjacent moments in the multiple pictures at different times are the same, for example, multiple pictures at different times are pictures separated by half an hour in sequence, and medical staff can quickly and clearly know whether the patient's posture has changed within the first time threshold range through these pictures without doing any operation, so as to efficiently judge how to turn the patient over at present.

[0090] While displaying risk warning information (such as risk warning information of the target part or the patient as a whole), or after the risk warning information is selected by the user, time information reflecting the time period during which the target part or the patient as a whole did not perform effective exercise can also be displayed on the above-mentioned display interfaces. There are many specific implementation methods for displaying time information reflecting the time period during which the target part or the patient as a whole did not perform effective exercise on the above-mentioned display interfaces, and three examples are given below for illustration.

[0091] In the first mode, the time information of each time period in which the target part does not make effective movement for a period exceeding the first time threshold can be presented in the display interface in the form of text within the preset monitoring duration. For the convenience of expression, the time period in which the target part does not make effective movement for a period (continuous duration) exceeding the first time threshold is called the target time period. In other words, the time interval between two adjacent effective movement events exceeds the first time threshold, and then the time interval is the target time period. The monitoring duration can be preset, for example, it can be the same day. The time information of each time period in which the duration of no effective movement exceeds the first time threshold can specifically include the starting time, the ending time and the duration of the time period. For example, there is such a time period on the same day, and the display interface can display: XX part did not make effective movement for two and a half hours from 9 am to 11:30 am. Similarly, the time information of each time period in which the patient as a whole does not make effective movement for a period exceeding the second time threshold can be presented in the display interface in the form of text within the preset monitoring duration, and the time information can also include the starting time, the ending time and the duration of the time period. Also for the sake of convenience, the time period (continuous duration) in which the patient does not perform effective exercise as a whole exceeds the second time threshold is called the target time period. The specific method is the same as the target part and will not be repeated here.

[0092] In the second method, multiple picture frames in the patient's video can be displayed on the display interface, and the time corresponding to the picture frame can be marked on the multiple picture frames of the video. This method is similar to the aforementioned solution of displaying the overall posture through the video window B, that is, the video window B displays multiple picture frames in the video, and the time corresponding to the picture frame is marked on the multiple picture frames, so that the medical staff can know in which time period the patient has made effective movements and in which time period he has not by comparing the time of these picture frames. In these picture frames, if the patient does not move for a long time, the image of the patient in the picture frame is basically the same, so multiple consecutive picture frames with basically the same patient image can also be marked.

[0093] In the third method, when risk warning information corresponding to a target part is generated once, it can be recorded as a risk warning event of the target part. In other words, when risk warning information corresponding to a target part is displayed once, a risk warning event of the target part occurs. Similarly, when risk warning information corresponding to the patient as a whole is generated once, it can be recorded as a risk warning event of the patient as a whole.

[0094] like Figure 2 and Figure 4As shown, a risk warning event trend graph D of the target part within the preset monitoring time can be displayed on the display interface. The risk warning event trend graph D of the target part is used to present the time information of each time period when the target part has not made effective movements for a period exceeding the first time threshold, that is, it is used to present the time information of each risk warning event. The risk warning event trend graph D of the target part can be used to reflect the trend of the risk warning events of the target part changing over time. In other words, a risk warning will be reflected on the trend graph D, which can also reflect the number, frequency and duration of the risk warning events. In this embodiment, the risk warning event trend graph D includes a timeline, and marks are made on the timeline according to the actual situation of the risk warning event. For example, each time a risk warning event occurs, a special graphic / symbol (rectangle in the figure) is used to mark the timeline once. The length of the target time period of the risk warning event can be reflected by the graphic / symbol along the span of the timeline. The duration of the target time period can be displayed on the graphic / symbol or at a position adjacent to the graphic / symbol. As shown in FIG. Figure 2 and 4 As shown, a risk warning event occurred within 0-24 hours, and the position of the rectangular figure roughly reflects the start time and end time of the target time period. The width of the rectangular figure and the time displayed on it reflect that the duration of the target time period is two hours and thirty-three minutes. The corresponding first time threshold can also be displayed on the risk warning event trend graph D, and the first time threshold in the figure is 2h. Similarly, the overall risk warning event trend graph of the patient within the preset monitoring time can be displayed on the display interface. The overall risk warning event trend graph of the patient is used to present the time information of each time period when the patient as a whole has not performed effective exercise for a period of time exceeding the second time threshold. The specific plan is the same as the above-mentioned target part. It only needs to replace the target part with the patient as a whole, and the first time threshold is replaced with the second time threshold. It will not be repeated here.

[0095] The monitoring duration can be adjusted in real time based on the user's operation, thereby updating the risk warning event trend chart of the patient as a whole and the target part in real time. In this way, through the risk warning event trend chart, medical staff can review the pressure sore risk warnings generated by the patient on the same day or in a certain period of time, and understand the patient's entire pressure sore care situation.

[0096] like Figure 5 As shown, the present invention also provides a method for prompting guardianship risks, comprising the following steps:

[0097] Step 1', obtaining the patient's image information. The specific process is the same as step 1 in the above embodiment, and will not be described in detail here.

[0098] Step 2': Detect the patient's motion according to the image information. The detected motion may be the motion of the patient as a whole, or the motion of one or more parts of the patient, or the motion of the patient as a whole and multiple parts, etc. The specific process has been described in detail in step 2 of the above embodiment, and will not be repeated here.

[0099] Step 3': Determine whether the patient's exercise condition meets the preset requirements based on the patient's exercise condition. The exercise condition may include one or more of the exercise amplitude, exercise duration, and exercise frequency. Similarly, the preset requirements may include one or more of the following three conditions:

[0100] Condition 1: the movement amplitude exceeds the preset amplitude threshold;

[0101] Condition 2: the duration of the exercise exceeds the preset time;

[0102] Condition 3: the movement frequency exceeds a preset frequency threshold.

[0103] If the movement condition only includes the movement amplitude or only condition 1 is used as the preset requirement, it can be determined whether the patient's movement amplitude exceeds the preset amplitude threshold. If the movement amplitude exceeds the preset amplitude threshold, the movement condition meets the preset requirement; otherwise, it does not meet the preset requirement.

[0104] If the exercise condition only includes the exercise duration or only condition 2 is used as the preset requirement, it can be determined whether the patient's exercise duration exceeds the preset duration. If the exercise duration exceeds the preset duration, the exercise condition meets the preset requirement; otherwise, it does not meet the preset requirement.

[0105] If the exercise condition only includes the exercise frequency or only condition 3 is used as the preset requirement, it can be determined whether the patient's exercise frequency exceeds the preset frequency threshold. If the exercise frequency exceeds the preset frequency threshold, the exercise condition meets the preset requirement; otherwise, it does not meet the preset requirement.

[0106] In this embodiment, the preset requirements include the above three conditions. Only when the three conditions are met at the same time, the exercise situation is considered to meet the preset requirements. Otherwise, the exercise situation is considered not to meet the preset requirements. More conditions are more likely to trigger the subsequent provision of risk warning information, so that the patient can be monitored more timely.

[0107] Since the patient's movement condition can be the movement condition of the patient as a whole and / or multiple parts, this step specifically needs to judge the movement condition of the patient as a whole and the parts separately. Specifically, the movement condition of each part can be judged separately according to the movement condition of each part whether it meets the preset requirements. If the movement condition of the part meets the preset requirements, it is determined that the part has done effective movement. If it does not meet the preset requirements, it is determined that the part has not done effective movement. No movement of the part also belongs to no effective movement. The patient's overall movement condition can be judged according to the patient's overall movement condition whether it meets the preset requirements. If it meets, it is determined that the patient has done effective movement as a whole. If it does not meet, it is determined that the patient has not done effective movement as a whole. No movement of the patient as a whole also belongs to no effective movement. The detailed process of judging the patient as a whole and each part has been described in detail in step 3, so it will not be repeated here.

[0108] Step 4', if the patient's movement within the preset time threshold does not meet the preset requirements, the corresponding risk warning information of the patient is displayed on the display interface. The risk warning information here can be based on the patient's overall movement, or it can be based on the movement of the part. That is, for the target part whose movement within the preset first time threshold does not meet the preset requirements, the risk warning information corresponding to the target part is displayed on the display interface. If the patient's overall movement within the preset second time threshold does not meet the preset requirements, the corresponding risk warning information of the patient is displayed on the display interface. The specific method of displaying the risk warning information is the same as step 4 of the above embodiment, and will not be repeated here.

[0109] Similarly, the time threshold can be determined based on the user's setting operation. Case information reflecting the patient's condition can also be obtained, and the time threshold is determined according to the case information; wherein, the more serious the patient's condition reflected by the case information, the smaller the time threshold; the milder the condition reflected, the longer the time threshold. Case information includes at least one of Braden score, perfusion status, nutritional status and personal information. Ambient humidity can also be obtained, and the time threshold is determined according to the ambient humidity; wherein, the greater the ambient humidity, the smaller the time threshold; the lower the ambient humidity, the longer the time threshold. The time threshold can include a first time threshold and a second time threshold, and then the user can set the time threshold for each part and the patient as a whole or the system can adaptively adjust it. The specific process has been described in detail in step 4 of the above embodiment, and will not be repeated here.

[0110] Step 5', while displaying the risk warning information, or after the risk warning information is selected by the user, the time information reflecting the time period when the patient did not do effective exercise is also displayed on the display interface. The patient's exercise condition does not meet the preset requirements and is considered to be ineffective exercise. It can also be implemented in three different ways. For example, the time information of each time period in which the patient did not do effective exercise for a preset monitoring duration exceeds the time threshold is presented in text on the display interface. For another example, the image information is a video captured by a camera, and multiple picture frames in the video are displayed on the display interface, and the time corresponding to the picture frame is marked on the multiple picture frames of the video. For another example, the risk warning information corresponding to the target part is generated once and recorded as a risk warning event; the risk warning event trend graph of the patient within the preset monitoring duration is displayed on the display interface, and the risk warning event trend graph of the patient is used to present the time information of each time period in which the local part or the whole of the patient did not do effective exercise for a duration exceeding the time threshold. Since the risk warning information can be for the patient as a whole or for the target part, the corresponding time information of the time period in which no effective exercise is for the patient as a whole or for the target part, so this step is also divided into two schemes of the patient as a whole and the target part. That is, while displaying the risk warning information corresponding to the target part, or after the risk warning information corresponding to the target part is selected by the user, the time information reflecting the time period during which the target part has not made effective exercise is also displayed on the display interface; and / or, while displaying the risk warning information corresponding to the patient as a whole, or after the risk warning information corresponding to the patient as a whole is selected by the user, the time information reflecting the time period during which the patient as a whole has not made effective exercise is also displayed on the display interface. The specific process has been described in detail in step 4 of the above embodiment, and will not be repeated here.

[0111] As can be seen from the above content, the above method can be applied to monitoring equipment, such as Figure 6 As shown, the monitoring device provided by the present invention includes: a first communication module 10, a second communication module 20, a human-computer interaction device 30 and a processor 40.

[0112] The first communication module 10 is used to obtain monitoring data of at least one vital sign parameter of the patient, usually obtaining monitoring data of multiple vital sign parameters. The monitoring device can be any one of a monitor, a local central station, a remote central station, a cloud service system, and a mobile terminal (PDA), and the corresponding first communication module 10 obtains monitoring data in different ways. For example, if the monitoring device is a monitor, the first communication module 10 can use a sensor, and the sensor is used to monitor the patient's vital sign parameters to obtain monitoring data of the vital sign parameters. The monitoring data of the vital sign parameters may include at least one of the types of vital sign parameters (such as electrocardiogram, respiration, non-invasive blood pressure, blood oxygen saturation, pulse, body temperature, invasive blood pressure, end-tidal carbon dioxide, respiratory mechanics, anesthetic gas, cardiac output, bispectral index, etc.), the values ​​of vital sign parameters, and the changing trend of the values ​​of vital sign parameters. For another example, the monitoring device can be a local central station, a remote central station, a cloud service system or a mobile terminal (PDA), then the first communication module 10 is a communication module or a communication interface, which is used to communicate with the monitor or wearable device to obtain the above-mentioned monitoring data from the monitor or wearable device.

[0113] The second communication module 20 is used to receive the patient's image information transmitted by the external device. Usually, the monitoring device does not have the function of directly collecting the patient's image information, so the second communication module 20 can use a communication module or a communication interface to receive the patient's image information collected by external devices such as cameras, infrared sensors, 3D depth sensors, etc.

[0114] The human-computer interaction device 30 is used for human-computer interaction. It may include an input device 320 for receiving user input, and a display 310 for outputting visual information. The input device 320 is configured to receive input from a user (usually an operator), for example, one or more of a mouse, a keyboard, a touch display, a trackball, and a joystick may be used to receive instructions input by the user. The user may perform input operations through the input device 320.

[0115] The display 310 is configured to output information, such as visual information. The display 310 may be a display having only a display function, or a touch display.

[0116] The processor 40 is configured to: display the above monitoring data on the display interface of the display 310; and also process the monitoring data of each vital sign parameter, for example, determine whether each vital sign parameter exceeds the corresponding threshold value, and if so, generate an alarm message and display the generated alarm message on the display interface.

[0117] The processor 40 is further configured to: obtain the patient's image information through the second communication module 20; detect the movement of one or more parts of the patient according to the image information; determine whether the movement of each part meets the preset requirements according to the movement of each part; for the target part whose movement does not meet the preset requirements within the preset first time threshold, display the risk warning information corresponding to the target part on the display interface of the display 310. That is, the processor 40 can execute Figure 1 The various steps of the embodiment shown in the figure can realize the prompt of the risk of pressure sore monitoring. Figure 1 The illustrated embodiments are not described in detail here.

[0118] The processor 40 can also be configured to: obtain the patient's image information through the second communication module 20; detect the patient's movement status based on the image information; determine whether the movement status meets the preset requirements based on the patient's movement status; if the patient's movement status does not meet the preset requirements within the preset time threshold, then display the patient's corresponding risk warning information on the display interface of the display 310; while displaying the risk warning information, or after the risk warning information is selected by the user, also display time information reflecting the time period when the patient did not do effective exercise on the display interface; the patient's movement status does not meet the preset requirements and is considered to be ineffective exercise. The risk warning information can be selected by the user operating the input device 320. That is, the processor 40 can execute Figure 5 The various steps of the embodiment shown in the figure can realize the prompt of the risk of pressure sore monitoring. Figure 5 The illustrated embodiments are not described in detail here.
