Description

Technical Field

[0001] This invention relates to the field of medical technology, and in particular to a smart bracelet for guiding and positioning during physical examinations and its usage system. Background Technology

[0002] With the development of medical and health management and the construction of smart hospitals, physical examination centers are gradually introducing information systems to manage physical examination items in a unified manner. Common methods include guiding examinees to complete the physical examination process in different departments through physical examination forms, display screens, or manual guidance. At the same time, some physical examination institutions have begun to use electronic queuing systems, indoor positioning technology, or wearable devices to record or prompt examinees' walking paths, queuing order, and some physiological indicators in order to improve the efficiency of physical examination organization and management level.

[0003] However, in existing technologies, physical examination guidance and physiological monitoring are usually independent of each other. The physical examination process is mostly carried out according to a preset order or static queuing rules, which makes it difficult to reflect the real-time physiological changes of the examinee during the physical examination. Moreover, the existing positioning or navigation methods mainly focus on spatial guidance and lack a coordination mechanism with medical process constraints and risk assessment, which can easily lead to limitations in the efficiency, rationality and safety of physical examinations.

[0004] Therefore, it is necessary to propose a new technical solution to improve the synergistic relationship between physical examination guidance and physiological state perception. Summary of the Invention

[0005] This application provides a smart bracelet and system for guiding and positioning during physical examinations, in order to improve the accuracy and adaptability of physical examination guidance.

[0006] This application provides a smart bracelet for guiding and locating during physical examinations, comprising: Wearing subject; The physiological sensing module, located inside the wearable body, is used to collect at least one vital sign data of the subject; The motion and environment sensing module is located inside the wearable body and is used to acquire information on the subject's motion status and spatial changes within the physical examination site. The positioning and communication module, located inside the wearable body, is used to interact with the information system of the medical examination site and determine the current location of the examinee; The processing module, located inside the wearable device, is used to fuse and analyze the collected data and generate physical examination guidance and control results; The prompting and interaction module, connected to the processing module, is used to output navigation, reminders, or alarm information to the examinee.

[0007] This application provides a smart bracelet system for guiding and locating users during physical examinations, including: A smart wristband for guiding and positioning during physical examinations is worn by examinees to collect vital sign data, motion and environmental perception data, and location information. The physical examination information management server communicates with the physical examination guidance and positioning smart bracelet to store physical examination item data associated with the examinee, spatial information of the physical examination location, and physical examination process constraint information; The physical examination guidance and collaborative processing module is located in the physical examination information management server, or in the computing node between the physical examination guidance and positioning smart bracelet and the physical examination information management server; the physical examination guidance and collaborative processing module is configured as follows: It receives location information and vital sign data uploaded by the smart wristband for physical examination guidance and positioning, and combines it with the physical examination item data and spatial information stored in the physical examination information management server to generate physical examination guidance information corresponding to the order of physical examination items performed by the examinee. During the physical examination guidance process, the execution status of the physical examination process is comprehensively evaluated based on the real-time changes in vital signs fed back by the physical examination guidance positioning smart bracelet; When the comprehensive assessment results indicate the presence of physiological abnormality risks or the physical examination process does not meet the preset medical constraints, physical examination process adjustment information is generated and sent to the physical examination guidance and positioning smart bracelet to trigger the physical examination guidance and positioning smart bracelet to make corresponding adjustments to the subsequent physical examination guidance strategy, thereby realizing dynamic physical examination guidance that coordinates the physical examination process with the examinee's real-time physiological state.

[0008] The beneficial effects of this application include: (1) By integrating the physiological sensing module, motion and environmental sensing module, and positioning and communication module into the smart bracelet for physical examination guidance and positioning, and by having the processing module perform fusion analysis on multi-source data, the unified physical examination guidance and the real-time status perception of the examinee are realized. This allows the physical examination guidance to no longer rely solely on static processes or human experience, but to be adjusted in real time based on the examinee's current location and status, thereby significantly improving the accuracy and adaptability of the physical examination guidance. (2) By introducing a physical examination guidance collaborative processing module into the system and combining it with the physical examination item data, spatial information, and process constraint information stored in the physical examination information management server, the execution status of the physical examination process is comprehensively evaluated. This enables the physical examination process to be dynamically optimized according to the examinee's real-time vital signs changes, effectively avoiding situations such as excessively long waiting times and improper item order caused by unreasonable process arrangements, thereby improving the overall efficiency of the physical examination. (3) When the system detects that the examinee has a physiological abnormality risk or the physical examination process does not meet the preset medical constraints, it can automatically generate physical examination process adjustment information and feed it back to the smart bracelet, thereby triggering the adjustment of the physical examination guidance strategy in a timely manner. This is conducive to identifying potential risks in advance during the physical examination process, improving the safety and medical rationality of the physical examination process, and reducing the possibility of abnormal situations being ignored.

[0010] Figure 2 This is a schematic diagram of a smart bracelet system for guiding and positioning during physical examinations, provided in the second embodiment of this application. Detailed Implementation

[0011] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0012] The first embodiment of this application provides a smart bracelet for guiding and positioning during physical examinations. Please refer to... Figure 1 This figure is a schematic diagram of the first embodiment of this application. The following is in conjunction with... Figure 1 The first embodiment of this application provides a detailed description of a smart bracelet for guiding and positioning during physical examinations.

[0013] Wearing Entity 101. The wearing entity 101 is the basic supporting structure of the health check-guided positioning smart bracelet. It is used to ensure the stable wearing of the smart bracelet on the wrist of the examinee or other suitable parts of the human body, and to provide physical installation space, electrical connection conditions, and necessary protective environment for the physiological sensing module, motion and environmental sensing module, positioning and communication module, processing module, and prompt interaction module.

[0014] In its specific implementation, the wearing body 101 includes a wearing component for fixing to the examinee's body and a functional support part integrally formed or detachably connected to the wearing component. The wearing component can take the form of a flexible wristband, a ring strap, or an adjustable fixing strap, and its size can be adjusted according to the wrist circumference of different examinees to ensure a good fit and comfort. The wearing component is usually made of medical-grade silicone, thermoplastic elastomer, or other non-irritating materials that can be repeatedly sterilized to meet the hygiene and safety requirements of the medical examination site and to avoid pressure or allergic reactions on the examinee's skin due to prolonged wear.

[0015] The functional support unit is used to accommodate and fix the various functional modules. It has at least one module mounting cavity inside for housing the physiological sensing module, motion and environmental sensing module, positioning and communication module, and processing module. The module mounting cavity uses an internal support structure to limit and fix each module, preventing relative displacement during physical examinations such as walking, turning, or going up and down stairs, thus ensuring the stability of the sensor data acquisition and communication process. The outer shell of the functional support unit can be made of engineering plastics or lightweight metal materials with a certain strength and impact resistance, ensuring a light overall weight while protecting the internal electronic components from drops and crushing.

[0016] The side of the wearable body 101 facing the human skin preferably has a contact interface. This contact interface can be a flat or slightly curved structure to adapt to the curvature of the human wrist and provide stable skin contact conditions for the physiological sensing module. For example, when the physiological sensing module includes an optical sensor, the structural design of the contact interface of the wearable body 101 enables the optical sensor to maintain a relatively fixed distance and angle with the skin, thereby reducing measurement errors caused by loosening of the wearer. To further improve the reliability of the fit, a flexible buffer layer can also be provided on the contact interface to enhance the contact stability between the module and the skin without affecting wearing comfort.

[0017] In terms of electrical structure, the wearable body 101 has a power supply space inside for installing the battery assembly and providing power to various functional modules via internal wires or flexible circuit boards. The power supply space is separated from the module mounting cavity by an isolation structure to prevent adverse effects from battery heat or mechanical deformation on the sensing modules. The wearable body 101 can also have a pre-installed charging port or a wireless charging coil on its outer shell, allowing the smart bracelet to be recharged during breaks in health checks or when not in use.

[0018] Furthermore, the wearable device 101 is designed with the environment of the medical examination site in mind. Its outer shell is at least sweat-proof, waterproof, or dustproof to ensure stable operation in high-traffic and complex environments. The size and weight of the wearable device 101 are carefully controlled to prevent examinees from experiencing significant discomfort due to wearing it during prolonged medical examinations, thus avoiding disruption to the continuity of the examination process due to poor wearing experience.

[0019] Through the above structural and functional design, the wearer 101 not only achieves reliable wearing and physical support for the smart bracelet for physical examination guidance and positioning, but also provides the necessary conditions for the stable operation of each functional module, enabling the smart bracelet to continuously and accurately collect data and execute the physical examination guidance function in real physical examination scenarios.

[0020] The physiological sensing module 102 is located inside the wearable body and is used to collect at least one vital sign data of the subject.

[0021] The physiological sensing module 102, located inside the wearer 101, is the core functional unit of the health check-guided positioning smart bracelet for acquiring the examinee's physiological state information. Its main function is to continuously or according to predetermined rules collect vital sign data reflecting the examinee's physical condition throughout the entire health check process, and output the collected data to the processing module 105 for subsequent health check-guided analysis and process control. The vital sign data mentioned here refers to objective measurement data that can directly or indirectly reflect the state of human physiological activity, including but not limited to one or more of the following: heart rate, blood oxygen saturation, pulse waveform, skin temperature, and heart rate variability parameters.

[0022] In its specific implementation, the physiological sensing module 102 includes at least one physiological signal acquisition unit and a signal conditioning and output unit connected thereto. The physiological signal acquisition unit can be configured according to the type of vital signs to be monitored. For example, when it is necessary to acquire heart rate or blood oxygen saturation, the physiological signal acquisition unit can use a photoplethysmography sensor, which acquires the raw optical signal related to changes in blood volume by emitting light of a specific wavelength onto the skin surface and receiving reflected or transmitted light signals; when it is necessary to acquire skin temperature, a thermistor or semiconductor temperature sensor can be used, with its sensing end arranged adjacent to the contact interface of the wearer 101 to ensure the stability of temperature measurement.

[0023] To ensure the reliability of the collected data, the physiological sensing module 102 is structurally designed to enable the physiological signal acquisition unit to form stable contact with the subject's skin or maintain a predictable relative position. For example, the transmitting and receiving windows of the optical sensor are exposed through the fitting interface of the wearing body 101, and a light-shielding structure is set around them to reduce the interference of ambient light on the measurement results; the temperature sensor contacts the skin through a thermally conductive layer, so that the temperature it measures can accurately reflect changes in the skin surface temperature.

[0024] The signal conditioning unit in the physiological sensing module 102 is used to process the raw signal output by the physiological signal acquisition unit. This processing includes at least amplification, filtering, and analog-to-digital conversion. Taking heart rate acquisition as an example, the raw signal output by the photoplethysmography sensor usually contains weak variations corresponding to the pulse cycle and noise introduced by motion or the environment. The signal conditioning unit retains the signal components corresponding to the heart rate range through bandpass filtering and suppresses DC components and high-frequency noise. Then, the processed analog signal is converted into a digital signal for use by the processing module 105.

[0025] Regarding the calculation of vital sign parameters, when the vital sign data is heart rate, the physiological sensing module 102 or processing module 105 can calculate the time interval between two adjacent pulse peaks based on the acquired pulse waveform signal and convert this time interval into heart rate per minute. For example, in a continuously acquired signal, if the time interval between two adjacent pulse peaks is detected to be 0.8 seconds, the corresponding heart rate is 60 divided by 0.8, which is 75 beats per minute. Similarly, when calculating blood oxygen saturation, it can be calculated based on the absorption ratio of different wavelength light signals within the pulse cycle. The calculation method can be implemented using existing mature algorithms, and the physiological sensing module 102 only needs to provide a stable and reliable raw optical signal input.

[0026] The physiological sensing module 102 can also be configured to operate according to a predetermined sampling strategy, which can be one or more of continuous sampling, periodic sampling, or event-triggered sampling. For example, when the examinee is walking around the medical examination site, the module can collect heart rate data at a higher frequency to capture physiological fluctuations that may occur during the examination; when the examinee is stationary waiting for the examination items, the sampling frequency can be reduced to reduce power consumption and extend battery life. The sampling strategy can be dynamically adjusted by the processing module 105 according to the current stage of the medical examination.

[0027] Through the above structure and working method, the physiological sensing module 102 can stably and accurately collect the vital signs data of the examinee during the physical examination, and provide a reliable data basis for the generation of subsequent physical examination guidance and control results, so that the physical examination guidance process can match the examinee's real physiological state.

[0028] The motion and environment sensing module 103 is installed inside the wearable body and is used to acquire the subject's motion status and spatial change information in the physical examination site.

[0029] The motion and environment sensing module 103, located inside the wearer 101, is a functional unit of the smart bracelet for guiding and positioning physical examinations. It senses the examinee's movement behavior and changes in spatial state within the examination venue. Its core function is to acquire data reflecting the examinee's walking, standing, turning, and spatial displacement characteristics, thereby providing basic information for physical examination guidance, positioning correction, and status judgment during the examination process. The "motion state" referred to here refers to the examinee's physical movement behavior and its changes during the physical examination, including but not limited to walking, standing, standing, turning, and climbing stairs. The "spatial change information" refers to information such as changes in the examinee's position, direction, or height relative to the internal spatial structure of the examination venue.

[0030] In a specific implementation, the motion and environment sensing module 103 includes at least an inertial motion sensing unit, and may further include an environmental parameter sensing unit as needed. The inertial motion sensing unit preferably includes an accelerometer and an angular velocity sensor, wherein the accelerometer is used to collect the linear acceleration changes of the wearer in the three-axis directions, and the angular velocity sensor is used to collect the rotational angular velocity changes of the wearer about each axis. Those skilled in the art will understand that the accelerometer and angular velocity sensor can be integrated into an inertial measurement unit, whose output data can reflect the motion state of the wearer in space.

[0031] By analyzing acceleration data, the basic movement behaviors of the examinee can be identified. For example, when the acceleration signal exhibits periodic changes in the vertical direction, it can be determined that the examinee is walking; when the amplitude of acceleration changes significantly decreases and tends to stabilize, it can be determined that the examinee is standing or waiting. To avoid interference from environmental vibrations or natural arm swinging, the raw acceleration signal output by the motion and environment sensing module 103 can be filtered first, retaining only the signal components that match the frequency range of human movement. The filtering can be implemented using low-pass filtering or band-pass filtering, and its specific parameters can be set according to the typical movement characteristics in the physical examination environment.

[0032] In calculating walking distance or steps, the motion and environment perception module 103 can identify gait cycles in acceleration signals. For example, if multiple periodic peaks are detected in continuously collected acceleration data, and the time interval between two adjacent peaks corresponds to one complete gait, the number of peaks can be used as the basis for step counting. If 20 peaks are detected within a certain time period, it can be determined that the subject has completed 20 steps. Based on this, if a preset average step length parameter is used, for example, an average step length of 0.6 meters, the walking distance within that time period can be calculated as 20 multiplied by 0.6 meters, or 12 meters. The average step length parameter can be preset or obtained by the system through a simple calibration method before the physical examination begins.

[0033] Data collected by the angular velocity sensor is used to determine the subject's turning behavior and changes in walking direction. For example, when a significant change in angular velocity around the vertical axis is detected and persists for a period of time, it can be determined that the subject has turned or adjusted their direction. By integrating the angular velocity, the corresponding turning angle information can be obtained, thereby determining whether the subject is going straight, turning left, or turning right. This information can be used in conjunction with the positioning module to correct the current position, or to determine whether the subject has deviated from the physical examination guidance path.

[0034] In some implementations, the motion and environment sensing module 103 may further include an environmental parameter sensing unit for collecting environmental information related to spatial changes, such as air pressure change information. Air pressure sensors can detect subtle changes in ambient air pressure. When a subject moves up or down floors within the examination facility, the ambient air pressure typically undergoes measurable changes. By analyzing the trend of air pressure changes, it can be determined whether the subject has experienced vertical displacement. For example, if a sustained drop in air pressure is detected within a short period, it can be determined that the subject is going upstairs or in an elevator ascending; conversely, it can be determined that the subject is going downstairs or in an elevator descending. This height change information can be used as part of the spatial change information to assist in guiding the examination process or to match it with the spatial structure information of the examination facility.

[0035] The motion state data and spatial change information collected by the motion and environment perception module 103 can be output to the processing module 105 according to a predetermined time interval or event triggering method. The event triggering method can include situations such as changes in motion state, transitioning from walking to standing still, or significant changes in direction. Based on this data, the processing module 105 can determine the current stage of the physical examination for the examinee, such as whether they are walking to the examination point or waiting in line, thereby providing a reliable basis for generating the physical examination guidance and control results.

[0036] The positioning and communication module 104 is located inside the wearable body and is used to interact with the information system of the physical examination site and determine the current location of the examinee.

[0037] The positioning and communication module 104, located inside the wearer 101, is the core functional unit of the health check-up guidance and positioning smart bracelet. It determines the examinee's real-time location within the health check-up venue and interacts with the venue's information system. Its function is not only to obtain the examinee's spatial location but also to provide necessary data channels for health check-up guidance, process coordination, and information updates. Here, "positioning" refers to determining the examinee's relative or absolute spatial location within the health check-up venue, including the area, floor, passageway, or location near a specific check-up point. "Communication" refers to the process of bidirectional data transmission between the smart bracelet and the health check-up information management server or other information systems.

[0038] In its implementation, the positioning and communication module 104 includes at least a wireless communication unit and a positioning signal processing unit that works in conjunction with it. The wireless communication unit can employ Bluetooth, Wi-Fi, or other short-range wireless communication technologies suitable for use within the medical examination facility. Its function is to achieve a stable connection between the smart bracelet and the information system within the medical examination facility while ensuring controllable power consumption. Through this wireless communication unit, the smart bracelet can upload its collected location information, vital sign data, or status information to the medical examination information management server, and can also receive medical examination process-related information, guidance data, or adjustment instructions from the server.

[0039] The positioning signal processing unit is used to calculate the current location of the examinee within the medical examination venue based on signal characteristics or other auxiliary information acquired during wireless communication. The signal characteristics may include wireless signal strength, signal propagation delay, signal arrival order, or signal identification information. Those skilled in the art will understand that several wireless signal sources or access points are typically pre-deployed within the medical examination venue, and their spatial locations are known within the system. The signal characteristics received by the smart bracelet at different locations will differ, and the current location can be inferred by analyzing these differences.

[0040] For example, in one implementation, the positioning and communication module 104 periodically receives signal strength values ​​from multiple fixed signal sources via a wireless communication unit and uses these signal strength values ​​as positioning input parameters. Suppose that at a certain moment, the smart bracelet receives signal strengths A, B, and C from three different signal sources. The positioning signal processing unit compares this set of signal strengths with a pre-established correspondence between signal characteristics and spatial locations in the examination site to determine the most matching spatial location area. If this correspondence indicates that when the signal strength combination is close to A = −60 dBm, B = −70 dBm, and C = −80 dBm, the examinee is usually located near the entrance of a certain examination department, then it can be determined that the examinee is currently in that location area.

[0041] In another implementation, the positioning and communication module 104 can also combine the motion state information provided by the motion and environment sensing module 103 to correct or continuously update the positioning results. For example, when the wireless signal strength fluctuates significantly in a short period of time but the motion sensing data shows that the subject is stationary, the positioning signal processing unit can reduce its sensitivity to instantaneous signal changes, thereby avoiding misjudgment of location due to communication interference; when the motion sensing data shows that the subject is walking continuously, the current location can be smoothly updated by combining the previous location result and walking direction information.

[0042] After determining the location, the positioning and communication module 104 can send the location information to the processing module 105 in a predetermined data format. The location information can be one or more of specific coordinate values, area identifiers, or checkpoint numbers. For example, the location information can be represented as "currently located in the waiting area of ​​Zone B on the second floor," or as an identifier of a node on the floor plan of the corresponding medical examination area. The processing module 105 generates a medical examination guidance and control result based on this location information and the medical examination process information.

[0043] In terms of communication functionality, the positioning and communication module 104 is also responsible for maintaining the communication status between the smart bracelet and the information system of the medical examination venue, and for sending and receiving data as needed. The communication content includes not only location information, but also information related to the medical examination process, guidance update information, and system status feedback information. The communication process can adopt a periodic reporting method or an event-triggered method, such as immediately transmitting data when the location information changes significantly or the medical examination process is adjusted.

[0044] To ensure reliable and real-time communication, the positioning and communication module 104 can be configured with a communication status detection mechanism to determine whether the current wireless connection is stable. When a communication interruption or signal quality degradation is detected, the module can temporarily buffer the collected data and send it all at once after communication is restored, thereby avoiding data loss from affecting the physical examination guidance.

[0045] Through the above structure and working method, the positioning and communication module 104 can provide stable, continuous and calibrable positioning capabilities for the smart bracelet within the physical examination site, and realize effective data interaction with the physical examination information management server, providing an accurate location information basis for the generation of physical examination guidance and control results, so that the entire physical examination guidance and positioning smart bracelet has good feasibility and application reliability in the actual physical examination environment.

[0046] The processing module 105, located inside the wearable body, is used to fuse and analyze the collected data and generate physical examination guidance and control results.

[0047] The processing module 105, located inside the wearer 101, is the core control unit in the health check guidance and positioning smart bracelet. It is used for multi-source data fusion, status judgment, and generation of health check guidance control results. Its function is to uniformly receive, correlate, and logically process various types of data from the physiological sensing module 102, the motion and environment sensing module 103, and the positioning and communication module 104, and based on this, generate control results that can be directly used for health check guidance. The "fusion analysis" mentioned here refers to aligning, logically correlating, and comprehensively judging data from different sources, types, and time scales to obtain comprehensive information that reflects the examinee's current health check status and guidance needs.

[0048] In a specific implementation, the processing module 105 may include a processor and a corresponding storage unit. The processor may be a microcontroller, an embedded processor, or other computing unit suitable for wearable devices. The storage unit is used to store program instructions, parameter configurations, and temporary data related to the physical examination guidance. The processing module 105 establishes electrical connections with various functional modules through an internal bus or flexible circuit board, thereby achieving real-time or near-real-time data reception.

[0049] The processing module 105 first performs basic data processing and time synchronization on the data from each module. For example, heart rate data collected by the physiological sensing module 102 may be output at a frequency of once per second, acceleration data collected by the motion and environment sensing module 103 may be output at a higher frequency, while location information provided by the positioning and communication module 104 may be updated at a lower frequency. By adding time stamps to the data or resampling according to a predetermined sampling period, the processing module 105 enables data from different sources to be compared and analyzed under the same time reference, thereby avoiding judgment bias caused by inconsistent data time.

[0050] After data processing is completed, the processing module 105 analyzes and judges the current state of the examinee. The state includes at least location, movement, and physiological status. Location indicates which area of ​​the examination site the examinee is currently in or which examination point they are approaching; movement indicates whether the examinee is walking, standing still, or turning; and physiological status indicates whether the examinee's vital signs are within the normal range. The processing module 105 can use these states as input conditions and match them with pre-stored examination process information to determine which stage of the examination process the examinee is currently in.

[0051] For example, when the location information received by the processing module 105 indicates that the examinee has entered the vicinity of a certain examination department, and the movement status changes from walking to standing still, and there are no abnormal fluctuations in the physiological state, the processing module 105 can determine that the examinee has arrived at the corresponding examination point and generate a physical examination guidance control result to prompt the examinee to enter the examination or wait for the examination. The physical examination guidance control result may include navigation end instructions, waiting prompts, or precaution reminders, etc.

[0052] In another scenario, when the processing module 105 detects abnormal changes in vital sign data output by the physiological sensing module 102 during the physical examination guidance process, such as a heart rate significantly exceeding the preset normal range within a short period, the processing module 105 can mark this physiological state as abnormal and, in conjunction with the current movement state and location information, determine the physical examination scenario in which the abnormality occurred. For example, if a sustained increase in heart rate is detected during walking, the processing module 105 can generate a physical examination guidance control result that prompts a slowdown in walking speed or a short rest, and output corresponding alarm or reminder information through the prompt interaction module 106.

[0053] Regarding the generation of physical examination paths or guidance logic, the processing module 105 can determine the next target examination point and guidance direction based on the current location provided by the positioning and communication module 104 and the physical examination item process information obtained from the physical examination venue information system. The guidance direction can be determined by comparing the relative relationship between the current location and the target examination point in the spatial information of the physical examination venue. For example, when the current location is identified as "Second Floor, Area A Passage" and the target examination point is identified as "Second Floor, Area C Radiology Department", the processing module 105 can generate a guidance control result of "walk forward and turn right" based on the pre-stored spatial topology relationship, and send the result to the prompting and interaction module 106 for output.

[0054] In scenarios involving simple calculations, the processing module 105 can also perform quantification on the data. For example, when determining whether the examinee has deviated from the predetermined physical examination path, the processing module 105 can calculate the distance difference between the current position and the expected path node. When this distance difference exceeds a preset threshold, it can be determined that the examinee has deviated from the path, and a redirection control result can be generated. Assuming the distance between the expected path node and the current position is 10 meters, and the system's preset allowable deviation threshold is 5 meters, the processing module 105 can determine that the current state is a deviation state and trigger a path correction prompt.

[0055] The physical examination guidance control results generated by the processing module 105 can be output to the prompting and interaction module 106 in the form of structured data. The control results include at least information such as guidance type, guidance content, and output priority. Based on the control results, the prompting and interaction module 106 provides the examinee with corresponding navigation instructions, operation reminders, or safety alarms.

[0056] Through the above methods, the processing module 105 achieves effective fusion and logical analysis of multi-source data, enabling the smart bracelet for guiding and positioning physical examinations to dynamically generate physical examination guidance control results based on the examinee's real-time location, movement behavior, and physiological state, thereby ensuring the continuity, adaptability, and safety of the physical examination guidance process.

[0057] Furthermore, the processing module is specifically used for: Based on the current location information obtained by the positioning and communication module and the spatial and process information corresponding to the physical examination items, a physical examination path guidance instruction is generated. During the physical examination guidance process, which is executed according to the physical examination path guidance instructions, the execution status of the physical examination process is dynamically evaluated by combining the vital sign data collected by the physiological perception module. When the dynamic assessment results indicate a risk of physiological abnormalities or that the physical examination conditions do not meet the preset medical constraints, the execution order or guidance strategy of subsequent physical examination items is adjusted, and corresponding guidance or warning information is output through the prompt interaction module so that the physical examination guidance process is adapted to the real-time physiological state of the examinee.

[0058] The processing module is the core control unit located within the smart bracelet for guiding and positioning during a physical examination. Its specific function is to continuously control and dynamically adjust the guidance process based on the examinee's real-time location, the spatial and procedural information of the examination items, and changes in the examinee's physiological state. The processing module first obtains the examinee's current location information through the positioning and communication module. This location information refers to data representing the examinee's position within the examination venue, which can be specific coordinates, area identifiers, checkpoint numbers, or node identifiers corresponding to the spatial model of the examination venue. Simultaneously, the processing module also acquires spatial and procedural information related to the examinee's examination items. Spatial information describes the physical distribution of each examination item within the examination venue, while procedural information describes the sequential requirements or execution constraints between examination items.

[0059] After obtaining the above information, the processing module generates a physical examination path guidance instruction based on the current location information and the spatial and process information corresponding to the physical examination items. This physical examination path guidance instruction refers to guidance and control information used to instruct the examinee to proceed from their current location to the next physical examination item. It includes at least a target examination point identifier and a walking direction or path prompt corresponding to that target examination point. When generating the physical examination path guidance instruction, the processing module considers the physical examination items that the examinee has not yet completed as a candidate set, filters out items that meet the execution conditions based on process information, and then determines the relative positional relationship by combining spatial information, thereby selecting the next physical examination item. For example, if the examinee has completed multiple examination items on one floor and is currently located in a first-floor corridor, while the next executable physical examination item is located in a certain examination department on the second floor, the processing module can generate guidance instructions based on the spatial topology of the physical examination site, directing the examinee to the corresponding floor and area.

[0060] After the physical examination pathway guidance instructions are generated and executed, the processing module does not remain static. Instead, it continuously integrates vital sign data collected by the physiological sensing module throughout the entire physical examination guidance process to dynamically assess the execution status of the examination procedure. This dynamic assessment refers to the real-time judgment made during the physical examination guidance process based on changes in the examinee's vital signs over time to determine whether the current physical examination procedure is still suitable for continuation. Vital sign data may include heart rate, blood oxygen saturation, or other parameters that reflect the examinee's physiological load or health risk. The processing module can compare the currently collected vital sign data with pre-set normal ranges to determine whether the examinee is in a safe state.

[0061] For example, if during the physical examination guidance process, the processing module continuously receives heart rate data of 110, 115, and 120 beats per minute, while the preset upper limit of normal heart rate is 100 beats per minute, the processing module can determine that the examinee currently has a physiological abnormality risk. Similarly, if a physical examination item has a fasting requirement as a medical constraint, and the processing module determines from system records that the examinee has not yet met this constraint, it can be determined that the current physical examination conditions do not meet the preset medical constraints. These medical constraints refer to the preconditions for execution determined by the physical examination item itself, including but not limited to fasting requirements, time interval requirements, or examination sequence requirements.

[0062] When the dynamic assessment results indicate a risk of physiological abnormalities or that the physical examination conditions do not meet preset medical constraints, the processing module will adjust the execution order or guidance strategy of subsequent physical examination items. These adjustments may include changing the selection result of the next physical examination item, postponing or skipping a certain physical examination item, or modifying the physical examination path guidance method. For example, if the examinee's heart rate is detected to be persistently high, the processing module can temporarily postpone examination items that originally required a longer walking distance and prioritize guiding the examinee to a nearby physical examination area or one where a short rest is permitted; if the physical examination conditions do not meet the fasting requirement, the processing module can remove the relevant examination items from the current execution order and regenerate a new, appropriate physical examination path guidance instruction.

[0063] After completing the above adjustments, the processing module outputs corresponding guidance or warning information to the examinee through the prompting and interaction module. The guidance information is used to inform the examinee of the new physical examination route or the next physical examination item, and the warning information is used to remind the examinee of the current physiological risks or physical examination limitations. For example, the prompting and interaction module can output information such as "Please slow down and take a short rest" or "The current examination item has been adjusted, please proceed to another examination point," so that the examinee can understand the changes in the physical examination process in a timely manner and make the corresponding cooperation.

[0064] Furthermore, when dynamically evaluating the execution status of the physical examination process, the processing module performs the following steps: The physiological sensing module acquires vital sign data collected within a continuous preset time window, and calculates the rate of change parameter representing the trend of physiological state change based on the vital sign data. Based on the motion state information obtained by the motion and environment perception module, the current physical examination stage is divided into one of the walking stage, waiting stage, or examination execution stage, and corresponding physiological assessment rules are selected for different physical examination stages. The rate of change parameter is matched and analyzed with the physiological assessment rules corresponding to the physical examination stage to determine whether the examinee has any physiological abnormality risk at the current physical examination stage. When a risk of physiological abnormality is identified, this risk will be used as the basis for adjusting the physical examination process, triggering adjustments to the execution order of subsequent physical examination items or the physical examination guidance strategy.

[0065] In this embodiment, the processing module is responsible for dynamically evaluating the execution status of the physical examination process during the physical examination guidance process. This evaluation is not based on physiological measurements at a single moment, but rather on the changing trends of vital signs over a continuous period, thus more accurately reflecting the examinee's physiological load and status changes. The continuously preset time window mentioned here refers to a continuous time interval pre-set by the system during the physical examination guidance process, used to collect vital sign data within this time interval. This time window can be set according to the physical examination scenario, for example, set to 30 seconds, 60 seconds, or other time lengths that can cover multiple heartbeat cycles or physiological reaction cycles. Its purpose is to avoid misjudgments caused by instantaneous fluctuations or occasional interference.

[0066] The processing module first acquires vital sign data collected within the continuous preset time window from the physiological sensing module. Vital sign data may include one or more of heart rate, blood oxygen saturation, pulse waveform parameters, or skin temperature. After acquiring multiple sets of vital sign data within this time window, the processing module calculates a rate of change parameter representing the trend of physiological state changes based on this data. This rate of change parameter is a numerical indicator used to quantify how quickly vital signs change over time; it can be calculated as the ratio of the difference in vital sign values ​​at adjacent time points to the time interval. For example, if the heart rate gradually increases from 80 beats per minute to 100 beats per minute within a continuous 60-second time window, the rate of change parameter can be calculated as (100−80)÷60, approximately 0.33 beats / minute / second. This rate of change reflects the strength of the upward trend in heart rate, not just the final value.

[0067] After calculating the rate of change parameter, the processing module, combined with the motion state information obtained by the motion and environment perception module, determines the current physical examination stage. The physical examination stage referred to here refers to the behavioral state stage of the examinee during the physical examination process, which includes at least the walking stage, the waiting stage, and the examination execution stage. The walking stage refers to the examinee's movement along the guided path within the examination area, usually accompanied by continuous walking and changes in direction; the waiting stage refers to the examinee's state of remaining still at the examination point or waiting area, with minimal or near-stationary movement; the examination execution stage refers to the examinee undergoing specific physical examination procedures, which may involve specific postures or restricted movement. The processing module can classify the current state into one of the aforementioned physical examination stages by analyzing motion characteristics such as the magnitude of acceleration change, the frequency of angular velocity change, and the duration of stillness.

[0068] After identifying the current stage of the physical examination, the processing module selects the corresponding physiological assessment rules for each stage. These physiological assessment rules are pre-defined criteria for judging physiological changes at different stages of the examination, used to distinguish between normal physiological responses and abnormal risks. For example, during the walking stage, a moderate increase in heart rate is normal, so the corresponding physiological assessment rule allows for a higher threshold for the rate of change. However, during the waiting or examination execution stage, the examinee is usually in a relatively static state. If vital signs still show a significant upward trend at this time, it is more likely to reflect potential risks, so the corresponding assessment rule uses a stricter threshold for the rate of change. For instance, during the walking stage, a heart rate change rate of less than 0.5 beats / minute / second can be set as normal, while during the waiting stage, a change rate exceeding 0.2 beats / minute / second is considered an abnormal risk signal.

[0069] Subsequently, the processing module performs a matching analysis between the calculated rate of change parameter and the physiological assessment rules corresponding to the current physical examination stage. This matching analysis compares the rate of change parameter with preset thresholds or judgment conditions in the physiological assessment rules to determine whether the examinee has any physiological abnormality risk at the current physical examination stage. For example, if the examinee is in the waiting stage, and the calculated heart rate change parameter is 0.35 beats / minute / second, and the assessment rules for this stage stipulate that a rate exceeding 0.2 beats / minute / second is considered abnormal, then the processing module determines that there is currently a physiological abnormality risk.

[0070] When the processing module determines that there is a risk of physiological abnormality, it does not merely record it. Instead, it uses this risk as a direct basis for adjusting the physical examination process, triggering adjustments to the execution order of subsequent examination items or the examination guidance strategy. These adjustments may include postponing examination items requiring high physical exertion, prioritizing static or low-risk examinations, or prompting examinees to slow down their walking speed or take short breaks during the examination guidance. For example, if a risk of physiological abnormality is detected during the waiting phase, the processing module can reorder incomplete examination items, allowing examinees to complete examinations near their current location first, reducing unnecessary walking distance and thus mitigating further risks.

[0071] Through the above consecutive steps, the processing module realizes a dynamic assessment mechanism based on the trend of vital signs changes, the identification of physical examination stages, and the stage-differentiated physiological assessment rules, so that the physical examination guidance process can respond to the changes in the examinee's physiological state in real time, rather than mechanically executing the preset process.

[0072] Furthermore, the processing module is also used for: Obtain the medical constraint information corresponding to the currently pending physical examination items. The medical constraint information includes at least one or more of the following: fasting requirements, physical examination time window requirements, or physical examination item sequence requirements. By combining the vital sign data collected by the physiological sensing module and the physical examination execution status information recorded during the physical examination guidance process, it is determined whether the examinee meets the aforementioned medical constraints. When it is determined that the examinee does not meet the medical constraints corresponding to the current physical examination item, the physical examination item is marked as postponed and removed from the current physical examination item set; The execution order or path guidance instructions for physical examination items are regenerated based on the removed set of physical examination items to prevent physical examination items that do not meet medical constraints from being guided to continue execution.

[0073] In this implementation, the processing module, having already completed the physiological abnormality risk assessment based on vital sign trends and the physical examination phase, further introduces medical constraints to judge and control the legality and medical compliance of the physical examination process. The medical constraints mentioned here refer to the execution prerequisites or limitations determined by the specific physical examination items themselves and generally recognized in medical practice. These are not simple management rules, but rather medical requirements that directly affect the accuracy of examination results and the safety of the examinee. The medical constraints include at least one or more of the following: fasting requirements, physical examination time window requirements, or requirements on the order of physical examination items, and can be pre-configured and stored by the physical examination information management system before the physical examination begins.

[0074] The processing module first obtains the medical constraint information corresponding to the currently pending physical examination item. The "currently pending physical examination item" refers to the physical examination item that the system determines to be guided to perform next based on the completion status of previous examinations and the current examination path guidance result. For example, after the examinee completes blood pressure measurement, if the system plans to proceed to imaging examination, then the imaging examination is considered the currently pending physical examination item. The processing module queries the medical constraint information associated with this physical examination item to determine whether there are any specific requirements before the item is performed.

[0075] After acquiring the medical constraint information, the processing module combines the vital sign data collected by the physiological sensing module with the examination execution status information recorded during the examination guidance process to determine whether the examinee meets the aforementioned medical constraint conditions. The examination execution status information mentioned here refers to data reflecting the actual execution of the examination process, including the examination start time, the list of completed examination items, the completion time of each examination item, and the current stage of the examination. Through this information, the processing module can make dynamic and context-sensitive judgments on the medical constraints, rather than relying solely on static conditions.

[0076] Taking fasting requirements as an example, fasting refers to a state of not consuming food or energy drinks within a certain period of time. This time is usually determined by the specific medical examination item; for example, examinees may be required to fast for 8 hours before the examination. When determining the fasting constraint, the processing module can calculate the duration since the examinee last ate or was allowed to eat, based on the start time of the medical examination, the current time, and the medical examination execution status information. If the system records show that the examinee has not performed any eating-related operations within 8 hours before the start of the medical examination, and the vital signs data do not show typical physiological changes after eating, then the fasting requirement can be determined to be met; otherwise, the fasting constraint is determined not to be met. For another example, in scenarios with medical examination time windows, some medical examination items are only allowed to be performed during specific time periods in the morning. The processing module can compare the current time with this time window; if the current time exceeds the allowed range, then the medical constraint is determined not to be met.

[0077] During the judgment process, the processing module does not rely solely on a single condition, but rather comprehensively considers vital sign data and the status of the physical examination. For example, when determining whether the fasting requirement is met, in addition to calculations based on time information, changes in heart rate, blood glucose-related physiological indicators, or body movement characteristics can be used as supplementary criteria to reduce the probability of misjudgment. This comprehensive judgment method makes the determination of medical constraints more reliable.

[0078] When the processing module determines that the examinee does not meet the medical constraints corresponding to the current physical examination item, it will mark the physical examination item as temporarily suspended. This suspended status means that the physical examination item will no longer be guided by the system as an executable item during the current stage of the physical examination, but it does not mean that the item is permanently canceled. Rather, it will be reintroduced into the physical examination process once the medical constraints are met. Simultaneously, the processing module will remove the physical examination item from the current set of physical examination items to ensure that the examinee is not guided to perform this non-compliant item in subsequent physical examination guidance processes.

[0079] After completing the above elimination operation, the processing module regenerates the execution order or path guidance instructions for the physical examination items based on the eliminated set of physical examination items. This regeneration refers to reordering or replanning the path for the remaining executable physical examination items without violating other medical constraints and physical examination procedure requirements. For example, if the originally scheduled next physical examination item is postponed because it does not meet the fasting requirement, the processing module can select an item from the remaining physical examination items that is not subject to fasting restrictions and is spatially close to the current location as the new next execution item, and generate the corresponding path guidance instructions.

[0080] Through the above process, the processing module can introduce a medical constraint judgment mechanism in real time during the physical examination guidance process, so that the physical examination process can not only achieve dynamic adaptation at the level of spatial path and physiological state, but also maintain continuous verification at the level of medical compliance, thereby avoiding examinees being incorrectly guided to perform physical examination items when they do not meet the medical conditions.

[0081] Furthermore, the processing module is also used for: Obtain the preset fasting time window, and determine the start time of the fasting time window and the current physical examination time based on the records of the physical examination information management system; Within the fasting determination time window, vital sign data output by the physiological perception module and body movement characteristic data output by the motion and environment perception module are collected and recorded. The body movement characteristic data includes at least periodic arm movement characteristics or short-term high-frequency activity characteristics. Based on the changes in physiological responses after eating and the body movement data reflected in vital signs data, a comprehensive judgment is made on whether there is suspected eating or drinking behavior. When the comprehensive assessment results indicate a risk of not meeting the fasting requirement, it is determined that the examinee does not meet the fasting medical constraint, and the corresponding physical examination item is marked as unexecutable, which is used to trigger the adjustment of the order of physical examination items or the physical examination guidance strategy.

[0082] In this embodiment, during the medical constraint determination process, the processing module introduces a fasting status determination mechanism based on a combination of time, changes in vital signs, and body movement characteristics for physical examination items requiring fasting. Fasting, as defined here, refers to the absence of food or energy-containing beverages consumed by the examinee within a predetermined time frame, thus ensuring the accuracy and comparability of the relevant physical examination items from a medical perspective. Since it is difficult to determine fasting status solely through manual reporting or static recording during actual physical examinations, this embodiment achieves dynamic and objective determination of fasting status through multi-source data fusion.

[0083] The processing module first obtains the preset fasting time window. The fasting time window is a continuous time interval used to determine whether the examinee meets the fasting requirements. Its length can be set according to the medical requirements of the specific medical examination item, such as 6 hours, 8 hours, or 12 hours. The start time of this time window can be automatically determined based on the allowed eating deadline or the appointment time recorded in the medical examination information management system, while the current examination time is obtained by the system in real time during the examination. For example, if a certain medical examination item requires at least 8 hours of fasting before the examination, and the allowed eating deadline recorded in the medical examination information management system is midnight, then the start time of the fasting time window is midnight. When the current examination time is 8:00 AM, the processing module can determine whether the fasting time has met the basic 8-hour requirement.

[0084] After determining the fasting time window, the processing module continuously collects and records vital sign data from the physiological sensing module and body movement characteristic data from the motion and environment sensing module within this time window. Vital sign data refers to parameters that reflect changes in the subject's physiological responses, such as heart rate, blood oxygen saturation, or pulse waveform characteristics. Body movement characteristic data refers to data reflecting the subject's upper limb or overall body activity patterns, including at least periodic arm movement characteristics or short-duration high-frequency activity characteristics. Periodic arm movement characteristics typically manifest as repeated acceleration changes with relatively stable amplitude and frequency within a short period; these characteristics are commonly seen during eating or drinking. Short-duration high-frequency activity characteristics manifest as multiple high-frequency acceleration fluctuations within a short period, such as frequent raising and lowering of the hand; these movements may also be related to eating or drinking behavior.

[0085] After collecting the aforementioned data, the processing module comprehensively determines whether there is any suspected eating or drinking behavior based on the changes in physiological responses after eating and the body movement characteristics reflected in the vital signs data. The changes in physiological responses after eating refer to measurable physiological changes that may occur after eating or drinking, such as short-term fluctuations in heart rate caused by non-exercise, or significant changes in pulse waveform characteristics. The processing module can determine whether there are any physiological responses inconsistent with the normal fasting state by comparing the changing trends of vital signs data within the fasting determination time window. For example, if a sustained increase in heart rate accompanied by changes in pulse waveform is detected within a short period of time without obvious walking or exercise, this can serve as an auxiliary basis for determining suspected eating or drinking behavior.

[0086] In the comprehensive judgment process, the processing module does not rely solely on a single feature, but rather performs correlation analysis between changes in vital signs and body movement characteristics. For example, if obvious periodic arm movements are detected within the fasting judgment time window, and vital sign data also show a trend consistent with post-eating responses, the processing module can determine that there is a high probability of suspected eating or drinking behavior. Conversely, if only slight body movement is detected but vital signs remain stable, the weight given to judging eating behavior can be reduced, thereby decreasing false positives. This comprehensive judgment method makes the assessment of fasting status more reliable and closer to actual physical examination scenarios.

[0087] When the overall assessment indicates a risk of not meeting the fasting requirement, the processing module determines that the examinee does not meet the fasting medical constraint and marks the corresponding physical examination item as unexecutable. The unexecutable state here means that, within the current stage of the physical examination, the system no longer considers the examination item as something that can continue to be guided, but rather it is temporarily excluded from the examination process. After marking the physical examination item as unexecutable, the processing module uses this assessment result as a trigger condition to adjust the execution order of the physical examination items or the physical examination guidance strategy. For example, it may guide the examinee to prioritize other physical examination items that are not subject to fasting restrictions, or prompt the examinee to wait until the fasting condition is met before performing the relevant examination.

[0088] Through the above technical process, the processing module transforms the fasting medical constraint, which originally relied on manual confirmation, into an executable technical judgment mechanism based on time windows, physiological response characteristics, and body movement behavior characteristics. This enables the smart bracelet for guiding and positioning physical examinations to dynamically and objectively determine the fasting status during the physical examination process and adjust the physical examination procedures accordingly.

[0089] Furthermore, the processing module is also used for: The system obtains a set of physical examination items that the examinee has not yet completed and the spatial location identifiers of the physical examination venues corresponding to each physical examination item in the set of physical examination items. Based on the current location information obtained by the positioning and communication module, the system determines the spatial node corresponding to the current location information and simultaneously determines the candidate access paths from the spatial node to the spatial location identifiers of the physical examination venues corresponding to each physical examination item. Based on the motion state information obtained by the motion and environment perception module and the vital sign change trend collected by the physiological perception module, the physiological load parameter per unit of walking of the examinee in the current physical examination stage is calculated, and based on the physiological load parameter per unit of walking and the walking distance of each candidate path, the path physiological load cost corresponding to each candidate path is calculated. Based on the constraints of the physical examination process, a subset of currently executable physical examination items is determined from the set of incomplete physical examination items. For physical examination items that do not belong to the subset of executable physical examination items but are equivalent to at least one physical examination item in the subset of executable physical examination items in terms of medical purpose, replacement candidate physical examination items are generated based on a preset medical equivalence mapping relationship to form an optional physical examination item set that includes the subset of executable physical examination items and replacement candidate physical examination items. For each physical examination item in the set of optional physical examination items, a comprehensive ranking cost is calculated. The comprehensive ranking cost includes at least the path physiological load cost corresponding to the physical examination item and the spatial proximity cost between the spatial location identifier of the physical examination site corresponding to the physical examination item and the current location information. The physical examination item with the smallest comprehensive ranking cost is selected as the next physical examination item to be executed. At the same time, the execution order of subsequent physical examination items is reconstructed accordingly, and an updated physical examination path guidance instruction is generated to drive the prompt interaction module to output guidance information corresponding to the updated physical examination path guidance instruction.

[0090] In this embodiment, based on the aforementioned physiological abnormality risk assessment and fasting medical constraint determination, the processing module further undertakes the dynamic reconstruction function of the physical examination path and the execution order of physical examination items. Its core objective is not simply to shorten the walking distance, but to reduce the overall physiological burden on the examinee during the physical examination process while ensuring medical compliance. To achieve the above objective, the processing module first obtains the set of physical examination items that the examinee has not yet completed. The set of physical examination items that have not yet been completed refers to all physical examination items recorded in the physical examination information management system at the current physical examination time that have not yet been marked as completed or unexecutable. At the same time, the processing module also obtains the spatial location identifier of the physical examination venue corresponding to each physical examination item in the set of physical examination items. The spatial location identifier of the physical examination venue is data used to describe the specific spatial location of the physical examination item in the physical examination venue. It can be in the form of room number, area number, coordinate point or spatial node identifier, as long as it can uniquely identify the corresponding location in the spatial model of the physical examination venue.

[0091] The processing module then determines the spatial node corresponding to the current location based on the current location information obtained by the positioning and communication module. This spatial node is an abstract representation in the spatial model of the medical examination site, used to describe the physical location of the examinee within the spatial topology. For example, in a building-based medical examination site, a spatial node could correspond to a corridor intersection, the entrance to a waiting area, or the door of an examination room. After determining the spatial node, the processing module further determines candidate paths from that spatial node to the spatial location markers corresponding to each medical examination item. Candidate paths refer to several feasible paths from the current spatial node to the target spatial location marker in the medical examination site spatial model; each candidate path includes path length information and a sequence of spatial nodes traversed.

[0092] After obtaining candidate paths, the processing module does not directly select based on path length, but instead introduces a physiological load assessment mechanism. Based on the motion state information obtained by the motion and environment perception module and the vital sign change trends collected by the physiological perception module, the processing module calculates the physiological load parameter per unit of walking for the examinee at the current examination stage. This physiological load parameter per unit of walking is used to quantify the intensity of physiological exertion generated by the examinee per unit walking distance or unit walking time. It reflects the correlation between heart rate variability, blood oxygen saturation, or other vital sign changes and walking behavior. For example, during the walking phase, if the examinee's heart rate increases from 90 beats per minute to 105 beats per minute over a known walking distance, the change in heart rate can be divided by the walking distance to obtain a parameter representing the physiological load per unit of walking, reflecting the examinee's sensitivity to walking load.

[0093] After obtaining the physiological load parameter per unit of walking, the processing module calculates the path physiological load cost for each candidate path based on this parameter and the walking distance of each candidate path. The path physiological load cost is an indicator used to characterize the overall physiological burden that walking along a candidate path may impose on the subject; it is at least related to the path length and the physiological load parameter per unit of walking. For example, when the physiological load parameter per unit of walking is 0.02 heart rate increments per meter, and the walking distance of a candidate path is 100 meters, the path physiological load cost for that path can be calculated as 2, which can then be used for comparison with other paths.

[0094] After calculating the physiological burden cost of the examination pathway, the processing module determines a subset of currently executable examination items from the set of incomplete examination items based on the examination process constraints. This subset of executable examination items refers to the set of examination items that, at the current examination time, neither violate medical constraints nor violate the required order of the examination process. For example, if an examination item is postponed due to failure to meet fasting requirements, it will not be included in the subset of executable examination items. Furthermore, the processing module generates replacement candidate examination items based on a preset medical equivalence mapping relationship for examination items that are not part of the subset but are medically equivalent to at least one examination item in the subset. This medical equivalence mapping relationship refers to the correspondence between different examination items that have equivalent or similar functions in medical diagnosis; for example, certain basic imaging examinations and another low-burden screening examination may have similar diagnostic value in specific scenarios. Through this mapping relationship, the processing module can introduce alternatives that are less burdensome or easier to implement without changing the medical goals of the physical examination, thereby forming a set of optional physical examination items that includes a subset of executable physical examination items and alternative candidate physical examination items.

[0095] After obtaining the set of available physical examination items, the processing module calculates the comprehensive ranking cost for each item in the set. The comprehensive ranking cost, as described here, is a comprehensive evaluation index used to prioritize different physical examination items. It includes at least the path physiological load cost of the corresponding physical examination item and the spatial proximity cost between the spatial location marker of the physical examination item and the current location information. The spatial proximity cost reflects the spatial proximity between the location of the physical examination item and the examinee's current location, and it can be quantified by walking distance, number of access nodes, or path complexity. For example, if two physical examination items have similar path physiological load costs, the physical examination item that is closer to the current location and has a simpler path can obtain a lower spatial proximity cost, thus having a higher priority in the comprehensive ranking.

[0096] After calculating the comprehensive ranking cost of each physical examination item, the processing module selects the item with the lowest comprehensive ranking cost as the next item to be performed. Subsequently, based on this selection, the processing module restructures the execution order of subsequent physical examination items and generates updated path guidance instructions. These updated instructions instruct the examinee to proceed from their current location to the selected next physical examination item, specifying the corresponding walking path. This updated path guidance instruction is sent to the prompting and interaction module, which then outputs corresponding guidance information to the examinee, such as direction indicators, distance prompts, or path change reminders.

[0097] Through the aforementioned series of technical processes, the processing module achieves dynamic reconstruction of the physical examination path and the execution order of examination items. This allows the physical examination guidance decision-making to no longer rely solely on static processes or the shortest path principle, but rather comprehensively considers the examinee's real-time physiological state, medical process constraints, and the spatial structure of the examination venue. This technically achieves intelligent physical examination guidance aimed at reducing physiological burden. This dynamic reconstruction mechanism makes the physical examination process safer and more rational.

[0098] The prompting interaction module 106 is connected to the processing module and is used to output navigation, reminder or alarm information to the examinee.

[0099] The prompting interaction module 106, connected to the processing module 105, is a functional unit in the health check guidance and positioning smart bracelet used to transmit the health check guidance control results to the examinee in a perceptible form. Its core function is to output navigation information, operation reminders, or safety alarm information to the examinee based on the health check guidance control results generated by the processing module 105, thereby guiding the examinee to complete various health check items according to the system's planned process within the health check site. The "prompting interaction" mentioned here refers to establishing direct information interaction with the examinee through one or more of the following methods: visual, auditory, or tactile, enabling the examinee to understand and execute health check guidance instructions without the need for additional staff guidance.

[0100] In a specific implementation, the prompting interaction module 106 includes at least one information output unit, which can be configured according to the structural form of the wearer 101 and the usage environment of the medical examination site. For example, the information output unit may include a display unit for displaying navigation directions, examination item names, or waiting prompts in the form of text, graphics, or symbols; it may also include a vibration unit for transmitting reminders or alarm information to the examinee through vibrations of different rhythms or intensities; and it may also include a sound output unit for playing voice prompts or alert sounds. Those skilled in the art will understand that the prompting interaction module 106 is not limited to having all of the above output methods simultaneously, but can select one or more combinations thereof according to the specific implementation.

[0101] The prompting interaction module 106 receives the physical examination guidance control results through an electrical or data connection with the processing module 105. The physical examination guidance control results can be transmitted in structured data form, which includes at least the prompt type, prompt content, and prompt priority. The prompt type distinguishes whether the currently output information is a navigation prompt, process reminder, or safety alarm; the prompt content indicates specific guidance information, such as "Proceed to the next checkpoint," "Please wait here," or "Please slow down"; the prompt priority determines the output order and method when multiple prompt messages exist simultaneously.

[0102] In navigation information output scenarios, the prompting interaction module 106 can provide directional guidance to the examinee based on the prompt content. For example, when the physical examination guidance control result generated by the processing module 105 indicates that the examinee needs to go straight ahead and turn right at the next intersection, the display unit can display the corresponding directional arrow and brief text description; if vibration is used for output, a short vibration can indicate continuing straight ahead, and two consecutive short vibrations can indicate that a turn is needed, so that the examinee can understand the navigation instructions without looking at the display interface.

[0103] In the context of a physical examination process reminder, the prompting interaction module 106 can output information related to the current stage of the examination to the examinee. For example, when the examinee arrives at the examination department and needs to wait to be called, the prompting interaction module 106 can display the message "Arrived at the examination point, please wait," or use a slight vibration to remind the examinee that the route guidance has been completed. These types of prompts typically have a low output priority to avoid causing unnecessary interference to the examinee.

[0104] In safety alarm scenarios, when the processing module 105 detects an abnormal physiological state or a risk in the physical examination process, the prompting interaction module 106 needs to output alarm information to the examinee in a more prominent manner. For example, when the processing module 105 determines that the examinee's heart rate has significantly increased within a short period of time and exceeded a preset threshold, the prompting interaction module 106 can simultaneously activate the vibration unit and the sound output unit, outputting a clear vibration pattern and alarm sound to attract the examinee's attention, and displaying the prompt message "Please stop walking and rest" on the display unit. The vibration pattern mentioned here can be distinguished by vibration frequency and duration; for example, continuous vibration for two seconds can indicate an emergency alarm, while short vibrations indicate a normal reminder.

[0105] The prompting and interaction module 106 can also manage different prompts according to their priority. When navigation prompts and safety alarms exist simultaneously, the prompting and interaction module 106 prioritizes outputting safety alarm information and resumes outputting navigation prompts only after the alarm is cleared or the examinee confirms. This priority control logic can be preset by the processing module 105 and transmitted to the prompting and interaction module 106 for execution through the physical examination guidance control results.

[0106] To ensure effective delivery of prompts, the prompting interaction module 106 can adapt its output method based on environmental conditions and wearing status. For example, in noisy environments during physical examinations, the prompting interaction module 106 can reduce its reliance on sound output and prioritize vibration or display. When the examinee's vision is limited, the prompting effect can be enhanced by varying the vibration rhythm. This adaptation method can be controlled by the processing module 105 in conjunction with motion status or historical interaction feedback.

[0107] Through the above structure and working method, the prompting interaction module 106 can transmit the physical examination guidance control results generated by the processing module 105 to the examinee in an intuitive, reliable and appropriate manner that meets the needs of the physical examination scenario. This enables the examinee to understand and respond to the physical examination guidance, process reminders or safety alarm information in a timely manner, thereby ensuring the feasibility, interaction effectiveness and overall user experience of the physical examination guidance and positioning smart bracelet in the actual physical examination environment.

[0108] In the above embodiments, a smart bracelet for guiding and locating during a physical examination is provided. Correspondingly, this application also provides a system for using the smart bracelet for guiding and locating during a physical examination. Since this embodiment, namely the second embodiment, is basically similar to the method embodiment, it is described simply; relevant details can be found in the description of the method embodiment. The method embodiment described below is merely illustrative.

[0109] The second embodiment of this application provides a smart bracelet system for guiding and positioning during physical examinations, including: The 201 smart bracelet for guiding and positioning during physical examinations is worn by examinees to collect vital sign data, motion and environmental perception data, and location information. The physical examination information management server 202 is connected to the physical examination guidance and positioning smart bracelet to store physical examination item data associated with the examinee, spatial information of the physical examination location, and physical examination process constraint information. The physical examination guidance collaborative processing module 203 is located in the physical examination information management server, or in the computing node between the physical examination guidance positioning smart bracelet and the physical examination information management server; the physical examination guidance collaborative processing module 203 is configured as follows: It receives location information and vital sign data uploaded by the smart wristband for physical examination guidance and positioning, and combines it with the physical examination item data and spatial information stored in the physical examination information management server to generate physical examination guidance information corresponding to the order of physical examination items performed by the examinee. During the physical examination guidance process, the execution status of the physical examination process is comprehensively evaluated based on the real-time changes in vital signs fed back by the physical examination guidance positioning smart bracelet; When the comprehensive assessment results indicate the presence of physiological abnormality risks or the physical examination process does not meet the preset medical constraints, physical examination process adjustment information is generated and sent to the physical examination guidance and positioning smart bracelet to trigger the physical examination guidance and positioning smart bracelet to make corresponding adjustments to the subsequent physical examination guidance strategy, thereby realizing dynamic physical examination guidance that coordinates the physical examination process with the examinee's real-time physiological state.

[0110] The described smart bracelet system for guiding and positioning during physical examinations is a collaborative operating system built around the management and dynamic guidance of examinees' physical examination processes within the examination venue. Its core lies in the continuous information interaction between the smart bracelet 201 and the physical examination information management server 202, and the unified coordination and dynamic adjustment of the physical examination process through the collaborative processing module 203, thereby achieving a coordinated match between the physical examination process and the examinee's real-time physiological state. This system is not a simple combination of individual devices, but rather, through clear functional division and information flow relationships, it enables physical examination guidance, process control, and risk assessment to form a closed-loop whole.

[0111] The smart bracelet 201 for guiding and locating during a physical examination is worn by the examinee and is used to continuously collect data related to the examinee's status throughout the entire physical examination process. The data includes at least vital sign data, motion and environmental perception data, and location information. Vital sign data reflects changes in the examinee's physiological state; motion and environmental perception data reflects the examinee's walking, standing, or turning behaviors within the examination venue; and location information indicates the examinee's current location within the examination venue or at the examination point. The smart bracelet 201 maintains a wireless connection with the physical examination information management server 202 and uploads the collected data to the physical examination information management server 202 or the physical examination guidance and collaborative processing module 203 according to predetermined rules or event triggering methods.

[0112] The physical examination information management server 202 is used to centrally store and manage basic information related to the physical examination process. Its stored content includes at least the physical examination item data associated with the examinee, the spatial information of the physical examination location, and the physical examination process constraint information. The physical examination item data may include a list of examinations the examinee needs to complete, the required order of each examination, and the corresponding examination location identifiers. The spatial information of the physical examination location may include the floor structure, corridor layout, distribution of examination departments, and their interconnections. The physical examination process constraint information refers to the medical or procedural restrictions imposed on the execution of physical examination items, such as fasting requirements, completion requirements within a specific time window, or the requirement that certain examinations must be completed before other examinations. This information can be stored in the physical examination information management server 202 before the physical examination begins and can be retrieved as needed during the examination process.

[0113] The physical examination guidance and collaborative processing module 203 is the core logical unit in this system used to realize collaborative control of the physical examination process. It can be deployed inside the physical examination information management server 202, or in an independent computing node between the physical examination guidance and positioning smart bracelet 201 and the physical examination information management server 202. Regardless of its specific deployment location, the physical examination guidance and collaborative processing module 203 receives location information and vital sign data uploaded from the physical examination guidance and positioning smart bracelet 201 through a communication interface, and can access the physical examination item data and spatial information stored in the physical examination information management server 202.

[0114] During the physical examination guidance phase, the physical examination guidance collaborative processing module 203 first generates physical examination guidance information corresponding to the execution order of the physical examination items based on the examinee's current location information and the physical examination items they have not yet completed, combined with the spatial information of the physical examination venue. The physical examination guidance information referred to here means guidance content that can instruct the examinee to proceed to the next examination point or physical examination area. For example, when the examinee has completed a blood test and is currently located in the waiting area on the first floor, and the next physical examination item is an imaging examination on the second floor, the physical examination guidance collaborative processing module 203 can generate guidance information pointing to the imaging examination area on the second floor and send this guidance information to the physical examination guidance positioning smart bracelet 201, which then drives the bracelet to output corresponding navigation prompts to the examinee.

[0115] During the physical examination guidance process, the physical examination guidance collaborative processing module 203 does not simply operate statically according to a preset procedure. Instead, it continuously receives real-time vital sign changes from the physical examination guidance positioning smart bracelet 201 and comprehensively evaluates the execution status of the physical examination process accordingly. This comprehensive evaluation refers to associating vital sign changes with the current stage of the physical examination, the characteristics of the examination items, and the constraints of the examination process. For example, if vital sign data shows a persistently higher-than-normal heart rate while the examinee is en route to a certain examination item, the physical examination guidance collaborative processing module 203 can combine this physiological state with the current walking stage of the physical examination scenario to determine if the examinee may have physical or health risks.

[0116] When the comprehensive assessment results indicate a risk of physiological abnormalities, or when it is determined that the current physical examination process does not meet the preset medical constraints, the physical examination guidance and collaborative processing module 203 will generate physical examination process adjustment information. This adjustment information may include instructions to adjust the order of physical examination items, instructions to postpone the execution of a certain physical examination item, or instructions to prompt the examinee to rest or wait. For example, when it is detected that the examinee is about to undergo a relevant examination item before the fasting requirement is met, the physical examination guidance and collaborative processing module 203 can generate adjustment information to postpone the execution of that examination item and prompt the examinee to complete other examination items that are not subject to fasting restrictions first.

[0117] After generating the physical examination process adjustment information, the physical examination guidance and collaborative processing module 203 sends the information to the physical examination guidance and positioning smart bracelet 201 via communication. Upon receiving the physical examination process adjustment information, the physical examination guidance and positioning smart bracelet 201 adjusts the subsequent physical examination guidance strategy accordingly, such as updating the navigation target, changing the prompt content, or outputting alarm information, so that the physical examination guidance process of the examinee can reflect the adjustment results of the physical examination process in a timely manner.

[0118] Through the above system structure and operation mode, the smart bracelet system for guiding and positioning physical examinations can achieve dynamic coordination between the physical examination process, spatial guidance and the real-time physiological state of the examinee during the physical examination. This makes the physical examination guidance no longer limited to a fixed process or static path, but can be flexibly adjusted according to the actual state of the examinee, thereby ensuring the rationality and safety of the physical examination process.

[0119] Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.
