Description

[0001] The original basis for this divisional application is patent application No. 202310564273.8, filed on May 18, 2023, entitled "A Vital Signs Monitoring and Transmission System". Technical Field

[0002] This invention relates to the field of medical device technology, and in particular to a method and apparatus for coordinated switching of detection cycle and power based on vital sign signals. Background Technology

[0003] With the rapid development of wireless sensor network (WSN) technology, its applications in daily life are becoming increasingly widespread. WSNs are application-oriented network systems closely aligned with the objective physical world, and their emergence and development have always been linked to applications. Over the years, through the efforts of researchers in various fields, WSN technology has been fully recognized and demonstrated in applications such as military, precision agriculture, security monitoring, environmental monitoring, construction, industrial monitoring, intelligent transportation, logistics management, free space exploration, smart homes, and medical monitoring. In the field of medical monitoring, WSN technology enables the wireless and long-distance transmission of vital sign data acquired by monitoring instruments at the patient's location to devices at the medical staff's location. This allows medical staff to monitor the patient's vital signs at any time, facilitating monitoring of the patient's condition and providing effective clinical diagnostic evidence.

[0004] Existing technologies, such as the vital signs monitoring device and method proposed in patent document CN105769147A, integrate a vital signs monitor onto a wristband. The vital signs monitor includes a vital signs detection module, a microcontroller, an A / D converter, a buzzer, and a transmission module. The microcontroller is connected to the vital signs detection module, A / D converter, buzzer, and transmission module. The vital signs detection module is used to acquire vital signs data. The wristband integrates the vital signs monitor, allowing the monitored person to wear it in real time for real-time data monitoring, such as body temperature, pulse, and blood oxygen saturation. The data is then sent to a mobile phone, which in turn sends it to a cloud server, enabling real-time monitoring of human health.

[0005] Existing technology, such as the vital signs monitoring method and system proposed in patent document CN115005828A, includes a vital signs monitoring system comprising a vital signs acquisition device, a signal relay device, and a signal analysis device. The vital signs monitoring method comprises: the vital signs acquisition device acquiring multiple vital signs signals from corresponding parts of the human body, processing the multiple vital signs signals to generate transmission data, and wirelessly transmitting the data to the signal relay device; the signal relay device receiving the transmission data sent by the vital signs acquisition device, processing the received transmission data to acquire multiple vital signs signals, and transmitting the multiple vital signs signals to the signal analysis device; and the signal analysis device receiving and processing the multiple vital signs signals to acquire multiple target vital signs signals, and processing the multiple target vital signs signals to acquire vital signs signal analysis results.

[0006] Existing technology, such as the signal transmission processing method for a mobile monitoring device proposed in patent document CN112137579A, includes: obtaining at least one vital sign parameter signal of a patient using at least one measuring sensor, wherein the measuring sensor can be attached to a relevant part of the patient's body; processing the at least one vital sign parameter signal into transmittable physiological data information; transmitting the physiological data information on a communication channel between a target device and a communication device based on a first operating power, wherein the communication device can be worn on the patient's body; detecting the distance between the patient wearing the communication device and the target device; determining a second operating power based on the distance; and transmitting the physiological data information on the communication channel between the target device and the communication device based on the second operating power, wherein the second operating power is different from the first operating power.

[0007] In existing technologies, when patient monitors transmit data wirelessly, they are typically limited by transmission distance. When the distance between the patient and the data analysis device exceeds a certain limit, the data analysis device may fail to receive data or receive incomplete data, leading to data loss. While increasing the transmission power of wireless data transmission is a common solution to this distance limitation, the increased transmission power of the monitor can become interference noise, severely affecting the operation of other medical devices. Furthermore, adjusting data transmission power solely based on distance has drawbacks. For example, when the amount of data to be transmitted increases, only the required transmission power for the distance is increased; conversely, when the amount of data to be transmitted increases while the distance is relatively small, existing solutions may actually reduce the transmission power, leading to increased transmission time. This is detrimental to timely acquisition of abnormal data when the patient's vital signs are abnormal. Moreover, dynamically adjusting transmission power based on real-time distance changes results in high computational and power consumption, leading to short operating times, especially for battery-powered miniature monitoring devices.

[0008] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0009] In view of the shortcomings of the existing technical solutions, this application proposes a system that can monitor vital signs and transmit vital sign signals to a target device, aiming to solve the problems of inaccurate transmission power adjustment and high energy consumption in transmission distance detection that leads to short working time in the existing technology.

[0010] This application proposes a vital signs monitoring and transmission system, comprising: at least one monitoring module for acquiring at least one vital signs signal of a patient; a processing module for converting the at least one vital signs signal acquired by the at least one monitoring module into transmittable physiological data information; and a transmission module for transmitting the transmittable physiological data information converted by the processing module to a target device.

[0011] Preferably, the processing module is configured to determine the detection time period for detecting the distance between the transmission module and the target device according to a preset rule based on at least one vital sign signal.

[0012] Preferably, the transmission module is configured to determine the transmission power for transmitting the physiological data information to the target device based on the transmission distance between the transmission module and the target device, which is updated according to the detection time period, and at least one vital sign signal.

[0013] According to a preferred embodiment, when the processing module detects the distance between the transmission module and the target device, it can switch between a first detection cycle and a second detection cycle based on vital signs signals. When the vital signs signals are stable, the processing module detects the transmission distance between the transmission module and the target device based on the first detection cycle; when the vital signs signals change abruptly, the processing module detects the transmission distance between the transmission module and the target device based on the second detection cycle.

[0014] According to a preferred embodiment, when the processing module processes multiple vital sign signals, if one of the vital sign signals suddenly changes, the processing module switches all the first detection cycles to the second detection cycle, wherein the first detection cycle is longer than the second detection cycle.

[0015] According to a preferred embodiment, the processing module is able to detect the transmission distance between the transmission module and the target device at least by means of measurement within the detection time period. The means of measurement is that the processing module obtains the physical distance between the transmission module and the target device by means of a ranging method, and the processing module uses the physical distance to characterize the transmission distance.

[0016] According to a preferred embodiment, the processing module is also able to detect the transmission distance between the transmission module and the target device in a calibrated manner at least during the detection time period, wherein the calibrated manner means that the processing module characterizes the transmission distance based on the channel attribute quality for signal transmission between the transmission module and the target device.

[0017] According to a preferred embodiment, the transmission power determined by the transmission module based on the transmission distance and / or vital sign signals is dynamic, wherein the transmission power is at least linearly related to the amount of change in the transmission distance; and the transmission power is at least related to the category of the vital sign signals.

[0018] According to a preferred embodiment, the transmission module can pre-set several power levels according to the change in transmission distance, and then the transmission module determines the transmission power level based on the transmission distance and / or the change in transmission distance fed back by the processing module.

[0019] According to a preferred embodiment, the transmission module can pre-set several corresponding power increments based on the type and / or state of vital signs signals. Then, the transmission module increases the transmission power at the current setting based on the vital signs signals fed back by the monitoring module. The types of vital signs signals can include the patient's pulse rate, respiratory rate, heart rate, body temperature, and / or blood pressure; the state of vital signs signals refers to normal and abnormal states, i.e., stable and abrupt changes.

[0020] According to a preferred embodiment, the transmission module is at least able to adjust the transmission time period based on the transmission distance and vital signs signals, and the transmission module dynamically adjusts the transmission time period based on the change in the transmission distance and the type and / or state of the vital signs signals.

[0021] According to a preferred embodiment, the system includes a verification device for data verification, wherein the verification device acquires the transmitted data sent by the transmission module and the received data received by the target device from the transmission module via a wired connection, and the verification device determines whether the data received by the target device is missing by comparing and analyzing the differences between the transmitted data and the received data.

[0022] This application proposes a design for detecting the distance between the transmission module and the target device under different conditions and according to different detection time periods. For example, the detection time period of this application is at least divided into a first detection period and a second detection period. The processing module can periodically detect the distance between the transmission module and the target device according to at least the first detection period and / or the second detection period. The first detection period of the processing module is longer than the second detection period, thereby increasing the time interval for the processing module to detect the transmission distance in the first detection period. This reduces the power consumption of the processing module for distance detection within the same period. Furthermore, the distance detection power of the processing module in the first detection period is less than the distance detection power in the second detection period, thereby further reducing the power consumption of the processing module for distance detection in the first detection period. Combining the above two methods can greatly save the power consumption of the processing module for distance detection, thereby extending the continuous working time of the micro monitoring device.

[0023] Furthermore, this application proposes a technical solution that combines transmission distance and vital sign signals to determine the transmission power. This avoids the problem of the power being automatically adjusted to low power when the detection distance is short, but when a large amount of data or even urgent data needs to be transmitted, the low power can lead to untimely data transmission or data loss. In the technical solution of this application, the transmission power level and transmission distance also show a linear correlation. However, in addition to adjusting the transmission power level, this application also designs corresponding power increments based on the type of vital sign signal. Thus, the transmission module adjusts the power level according to the transmission distance, and adds the power increment set according to the vital sign signal when the transmission power level is determined, thereby ensuring that the data can be transmitted completely.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1 Figure 1 The diagram illustrates the logical relationship between the various modules of a vital sign monitoring and transmission system according to this application, including: at least one monitoring module 100 for acquiring at least one vital sign signal of a patient; a processing module 200 for converting the at least one vital sign signal acquired by the at least one monitoring module 100 into transmittable physiological data information; and a transmission module 300 for transmitting the transmittable physiological data information converted by the processing module 200 to a target device 500.

[0028] According to a preferred embodiment, the processing module 200 is configured to determine the detection time period for detecting the distance between the transmission module 300 and the target device 500 based on at least one vital sign signal according to a preset rule.

[0029] To address the following issues with existing technologies, a method of dynamically adjusting transmission power based on real-time distance detection is proposed: Current patient monitors, when transmitting data wirelessly, are limited by transmission distance. This is typically addressed by increasing the transmission power of the wireless data transmission. However, this increased transmission power can become interference noise, severely affecting the operation of other medical devices. Furthermore, the existing method of dynamically adjusting transmission power based on real-time distance detection leads to increased power consumption, especially for battery-powered miniature monitoring devices 400. Their single-cycle operating time depends on the battery's lifespan; in other words, for the same miniature monitoring device 400, the more power it consumes per unit time, the shorter its continuous operating time.

[0030] Based on the aforementioned deficiencies, this application proposes a design that detects the distance between the transmission module 300 and the target device 500 under different circumstances and according to different detection time cycles. For example, the detection time cycle of this application is at least divided into a first detection cycle and a second detection cycle. The processing module 200 can periodically detect the distance between the transmission module 300 and the target device 500 according to at least the first detection cycle and / or the second detection cycle. The first detection cycle of the processing module 200 is longer than the second detection cycle, thereby increasing the time interval for the processing module 200 to detect the transmission distance in the first detection cycle. This reduces the power consumption of the processing module 200 for distance detection within the same period. Furthermore, the distance detection power of the processing module 200 in the first detection cycle is less than the distance detection power in the second detection cycle, thereby further reducing the power consumption of the processing module 200 for distance detection in the first detection cycle. Combining the above two methods can greatly save the power consumption of the processing module 200 for distance detection, thereby extending the continuous working time of the micro monitoring device 400.

[0031] Preferably, the reason why the first detection cycle and the second detection cycle can be designed in the above manner is that the processing module 200 can determine the detection time cycle for detecting the distance between the transmission module 300 and the target device 500 according to a preset rule based on at least one vital sign signal.

[0032] Preferably, the so-called preset rule means that when the processing module 200 detects the distance between the transmission module 300 and the target device 500, it can switch between a first detection cycle and a second detection cycle based on the vital signs signal. Specifically, when the vital signs signal is stable, the processing module 200 detects the transmission distance between the transmission module 300 and the target device 500 based on the first detection cycle; when the vital signs signal changes abruptly, the processing module 200 detects the transmission distance between the transmission module 300 and the target device 500 based on the second detection cycle.

[0033] Specifically, when vital signs are stable, the data transmission is not urgent, and the requirements for transmission distance are relatively relaxed. Therefore, the time interval for distance detection can be extended, and the detection power can be reduced. However, when vital signs suddenly change or experience abnormal fluctuations, the data needs to be transmitted to the target device 500 at the medical staff's location as quickly as possible. Furthermore, the transmission quality must be fully guaranteed. Therefore, the current transmission distance needs to be calculated as soon as possible so that the transmission module 300 can adjust the appropriate transmission power to avoid problems such as slow transmission or even data loss due to the data transmission power being incompatible with the transmission distance.

[0034] Preferably, when processing multiple vital sign signals, the processing module 200 switches all first detection cycles to second detection cycles in the event of a sudden change in one of the vital sign signals, wherein the first detection cycle is longer than the second detection cycle. Specifically, the monitoring module 100 can acquire at least one vital sign signal, or it can acquire multiple vital sign signals. More specifically, the vital sign signals may be the patient's pulse rate, respiratory rate, heart rate, body temperature and / or blood pressure, etc.

[0035] Preferably, the processing module 200 is able to detect the transmission distance between the transmission module 300 and the target device 500 by means of measurement within the detection time period. The means of measurement is that the processing module 200 obtains the physical distance between the transmission module 300 and the target device 500 by means of a distance measurement method, and the processing module 200 uses the physical distance to characterize the transmission distance.

[0036] Specifically, the physical distance measurement methods include at least infrared ranging, microwave ranging, or ranging using a GPS positioning map, that is, displaying the location of the target device 500 and the location of the patient wearing the communication device on the map to obtain the physical distance between the two.

[0037] Preferably, the processing module 200 can also detect the transmission distance between the transmission module 300 and the target device 500 in a calibrated manner during the detection time period. The calibration means that the processing module 200 characterizes the transmission distance based on the channel attribute quality for signal transmission between the transmission module 300 and the target device 500.

[0038] Preferably, the calibration method specifically refers to the processing module 200 detecting the transmission signal on the communication channel between the target device 500 and the communication device, and determining the channel attribute quality based on the detected transmission signal. The processing module 200 then determines the transmission distance based on the channel attribute quality. For example, determining the transmission distance based on the channel attribute quality can be based on the relationship between the channel attribute quality and the transmission distance. For instance, a deterioration in channel attribute quality indicates a greater transmission distance between the patient wearing the communication device and the target device 500; conversely, a better channel attribute quality indicates a smaller transmission distance. Therefore, the change in transmission distance can be obtained based on the relationship between channel attribute quality and the transmission distance, thereby enabling the determination of the transmission distance based on the channel attribute quality.

[0039] Preferably, the processing module 200 evaluates channel attribute quality based on at least one or more of the following parameters: The signal strength when transmitting data between the transmission module 300 and the target device 500; The signal-to-noise ratio during data transmission between the transmission module 300 and the target device 500; Packet loss rate when transmitting data between transmission module 300 and target device 500.

[0040] Specifically, channel attribute quality deteriorates, which can manifest as decreased signal strength, reduced signal-to-noise ratio, and / or increased packet loss rate; conversely, channel attribute quality improves. Alternatively, channel attribute quality can be assessed and determined based on at least two or three of the aforementioned factors—signal strength, signal-to-noise ratio, and packet loss rate—to determine the change in distance between the target device 500 and the communication device.

[0041] Preferably, the distance detection in the first detection cycle and the second detection cycle can be one or more of the measurement method and the calibration method. In the measurement method, the distance detection power specifically refers to the infrared emission power and microwave emission power mentioned above, such as infrared ranging and microwave ranging methods. In the calibration method, the distance detection power specifically refers to the power of sending the detection signal mentioned above.

[0042] Example 2 This embodiment is an improvement and supplement to embodiment 1, and repeated content will not be repeated.

[0043] Figure 1 The diagram illustrates the logical relationship between the various modules of a vital sign monitoring and transmission system according to this application, including: at least one monitoring module 100 for acquiring at least one vital sign signal of a patient; a processing module 200 for converting the at least one vital sign signal acquired by the at least one monitoring module 100 into transmittable physiological data information; and a transmission module 300 for transmitting the transmittable physiological data information converted by the processing module 200 to a target device 500.

[0044] According to a preferred embodiment, the transmission module 300 is configured to determine the transmission power for transmitting physiological data information to the target device 500 based on the transmission distance between the transmission module 300 and the target device 500, which is updated according to the detection time period, and at least one vital sign signal.

[0045] Existing technologies have proposed technical solutions for adjusting the transmission power of the transmission module 300 based on the transmission distance. However, adjusting the data transmission power solely based on distance has certain drawbacks. For example, when the amount of data to be transmitted increases, only the transmission power required for the distance increases. In other words, when the amount of data to be transmitted increases while the distance decreases relatively, the existing technology would actually reduce the transmission power, leading to an increase in the time required to transmit data. This is not conducive to timely acquisition of abnormal data information when the patient's vital signs are abnormal.

[0046] To address the aforementioned shortcomings, this application proposes a technical solution that combines transmission distance and vital sign signals to jointly determine transmission power. This avoids the problem of automatically adjusting the power to low when the detection distance is short, even when a large amount of data or urgent data needs to be transmitted, resulting in untimely or lost data transmission due to low power. In this application's technical solution, the transmission power level also exhibits a linear correlation with the transmission distance. However, in addition to adjusting the transmission power level, this application also designs corresponding power increments based on the type of vital sign signal. Consequently, the transmission module 300 adjusts the power level according to the transmission distance and, given the determined transmission power level, adds the power increment set according to the vital sign signal, thereby ensuring that the data can be transmitted completely.

[0047] Preferably, the transmission power determined by the transmission module 300 based on the transmission distance and / or vital sign signals is dynamic, wherein the transmission power is at least linearly related to the amount of change in the transmission distance; and the transmission power is at least related to the category of the vital sign signals.

[0048] Preferably, the transmission power is at least linearly related to the change in transmission distance, meaning that the transmission module 300 can at least pre-set several power levels according to the change in transmission distance, and then the transmission module 300 determines the transmission power level based on the transmission distance and / or the change in transmission distance fed back by the processing module 200.

[0049] Specifically, the transmission module 300 can determine the specific transmission power based on changes in distance. For example, if the transmission distance and operating power are linearly related, the transmission module 300 can adjust the transmission power to the corresponding level by progressively increasing or decreasing the power according to a pre-set number of steps or levels based on changes in the transmission distance. In actual use, if the channel quality of data transmission between the transmission module 300 and the target device 500 deteriorates, indicating a larger transmission distance between the patient wearing the communication device and the target device 500, the transmission module 300 will adjust the transmission power to a higher level based on the transmission distance; conversely, if the channel quality improves, indicating a smaller distance between the transmission module 300 and the target device 500, the transmission module 300 will adjust the transmission power to a lower level based on the transmission distance. More specifically, taking the distance between the transmission module 300 and the target device 500 varying within 100m as an example, several power levels can be set according to the distance. For example, the distance can be divided into 20m segments, with one power level added for each 20m segment, and the power increase for each power level is the same. Another example is to set four power levels for 0-10m, 10-30m, 30-60m, and 60-100m, which are respectively the first, second, third, and fourth power levels, and the power increase for each power level increases accordingly.

[0050] Preferably, the transmission module 300 can pre-set several corresponding power increments based on the type and / or state of the vital signs signals, and then the transmission module 300 increases the transmission power at the current level based on the vital signs signals fed back by the monitoring module 100. The types of vital signs signals can be the patient's pulse rate, respiratory rate, heart rate, body temperature and / or blood pressure, etc.; the state of the vital signs signals refers to normal state and abnormal state, that is, stable state and abrupt change state.

[0051] Preferably, the power increment set by the transmission module 300 according to the type of vital sign signal means that the amount of data converted into physiological data information may be different for each type of vital sign signal. For example, body temperature and heartbeat change relatively little in a short period of time, but heartbeat is active in a short period of time. Therefore, the size of the physiological data information of body temperature and heartbeat obtained may not be the same, and usually is different. As a result, the power required to transmit physiological data information is also different, and thus the power increment corresponding to body temperature and heartbeat is also different.

[0052] Preferably, the power increment set by the transmission module 300 according to the type of vital sign signal means that for a certain type of vital sign signal, which has at least two states, namely normal state and abnormal state, the power increment corresponding to the same vital sign signal includes at least a first increment and a second increment, wherein the first increment is slightly smaller than the second increment. The first increment is the power increment when the vital sign signal is in the normal state, and the second increment is the power increment when the vital sign signal is in the abnormal state. For the same type of vital sign signal, the information data in the abnormal state is more urgent and necessary. Therefore, more power needs to be added on the basis of the same transmission power level to leave enough spare power to transmit the abnormal state information and avoid the problem of untimely or missed transmission of abnormal information.

[0053] Preferably, the transmission module 300 is at least able to adjust the transmission time period based on the transmission distance and vital signs signals, and the transmission time period is dynamically adjusted based on the change in transmission distance and the type and / or state of vital signs signals.

[0054] Preferably, the transmission time period of the transmission module 300 is at least divided into a first transmission period and a second transmission period, wherein the first transmission period is longer than the second transmission period. The transmission module 300 selects whether to transmit physiological data information in the first transmission period or the second transmission period based on whether the vital sign signal fed back by the processing module 200 is abnormal.

[0055] Specifically, when the processing module 200 reports stable vital signs, the transmission module 300 transmits physiological data information based on the first transmission cycle according to the corresponding transmission power (including power level and power increment). The time interval of the first transmission cycle is longer than that of the second transmission cycle, so the transmission module 300 consumes less power in the first transmission cycle, which helps extend the battery life of the micro monitoring device 400.

[0056] Specifically, when the processing module 200 reports abnormal vital signs, the transmission module 300 transmits physiological data information based on the second transmission cycle according to the corresponding transmission power (including power level and power increment). The time interval of the second transmission cycle is shorter than that of the first transmission cycle. Thus, the transmission module 300 can send physiological data information at a faster frequency during the second transmission cycle, which helps medical staff to detect the patient's abnormality in a timely manner.

[0057] In this application, the monitoring time period, detection time period, and transmission time period can be the same or different. Specifically, the monitoring time period refers to the monitoring module 100 monitoring the vital signs signals of the corresponding body parts of the human body according to the monitoring time period; in other words, the monitoring module 100 monitors the vital signs signals according to the time intervals within the monitoring time period. The detection time period refers to the processing module 200 detecting the distance between the transmission module 300 and the target device 500 according to the detection time period; in other words, the processing module 200 detects the distance between the transmission module 300 and the target device 500 according to the time intervals within the detection time period. The transmission time period refers to the transmission module 300 transmitting the acquired physiological data information to the target device 500 according to the transmission time period; in other words, the transmission module 300 transmits the acquired physiological data information according to the time intervals within the transmission time period.

[0058] Example 3 Figure 1 The diagram illustrates the logical relationship between the various modules of a vital sign monitoring and transmission system according to this application, including: at least one monitoring module 100 for acquiring at least one vital sign signal of a patient; a processing module 200 for converting the at least one vital sign signal acquired by the at least one monitoring module 100 into transmittable physiological data information; and a transmission module 300 for transmitting the transmittable physiological data information converted by the processing module 200 to a target device 500.

[0059] According to a preferred embodiment, the monitoring module 100 can be attached to a relevant part of the patient's body to obtain vital signs signals at that part of the patient's body.

[0060] Preferably, in this embodiment, at least one monitoring module 100 may be a sensor, etc., used to measure the patient's pulse rate, respiratory rate, heart rate, body temperature and / or blood pressure.

[0061] Specifically, the corresponding pulse monitoring module 100 can be attached to the patient's wrist or fingers.

[0062] Specifically, the monitoring module 100 for measuring respiratory rate can use an electrocardiogram sensor attached to a relevant location on the patient's chest, such as near the heart, to measure respiratory rate using impedance breathing.

[0063] Specifically, the temperature monitoring module 100 can be attached to the patient's armpit, mouth, or anus.

[0064] Specifically, the blood pressure monitoring module 100 can be attached to the patient's arm. For example, the blood pressure monitoring module 100 can use a photoelectric sensor or a combination of an air pump and a cuff to measure blood pressure inflation or deflation to obtain blood pressure values.

[0065] Specifically, the heart rate monitoring module 100 can be attached to a relevant location on the patient's chest, such as near the heart, using an electrocardiogram sensor with electrode pads. The specific attachment location can be adjusted according to the actual situation, and no limitation is made here.

[0066] Preferably, at least one monitoring module 100 can collect at least one vital sign parameter signal of the patient at a certain interval frequency or continuously. The final vital sign parameter signal can be recorded in digital form or in graphical form, without any limitation.

[0067] Preferably, the target device 500 and the mobile monitoring device are physically separated, and are two independent devices. To facilitate medical staff to receive the patient's vital signs signals acquired by the monitoring module 100 at all times, the target device 500 can be placed in the place where medical staff spend the most time, such as the nurses' station; or, the target device 500 can also be set as a portable mobile device, which is convenient for medical staff to carry with them.

[0068] Preferably, the monitoring module 100 is capable of monitoring the patient's vital signs signals at least according to a monitoring time period, wherein the monitoring time period includes at least a first monitoring period and a second monitoring period, wherein the first monitoring period is longer than the second monitoring period.

[0069] Preferably, the monitoring module 100 typically monitors the patient's vital signs according to the first monitoring cycle and transmits the monitored vital signs to the processing module 200 for processing. If the processing module 200 detects an abnormality in the vital signs, it will send a signal to the monitoring module 100. The monitoring module 100 will then immediately adjust the first monitoring cycle to the second monitoring cycle, shortening the monitoring time interval and fully capturing the dynamics of the vital signs in case of an abnormality.

[0070] According to a preferred embodiment, at least one monitoring module 100, a processing module 200, and a transmission module 300 are configured together in a miniature monitoring device 400. The miniature monitoring device 400 can be attached to or worn on a specific body part of the patient's body to monitor the vital signs signals of that specific body part.

[0071] Based on the technical solution of this application, this embodiment also provides an application scenario for a vital signs monitoring and transmission system, such as... Figure 2As shown, A is a non-invasive blood pressure monitor (NIBP), B, C, and D are electrode pad sensors for measuring electrocardiogram, E is an anti-defibrillation module, F is a wearable device F in the miniature monitoring device 400 that is worn on the patient and integrates a processing module 200 and a transmission module 300, G is a transmission line, H is the target device 500, and I and J indicate the direction of data transmission, such as... Figure 2 As shown, B, C, D, and E can be connected to the wearable device F, which integrates the processing module 200 and the transmission module 300, via a transmission line G. The transmission line G is used for data transmission and power supply. The blood pressure measuring device A and the transmission module 300 of F worn by the patient in the mobile monitoring device can transmit data via Bluetooth Low Energy (BLE). That is, the electrocardiogram measuring electrode pads B, C, and D transmit the collected vital sign information to the transmission module 300 in the wearable device F via the transmission line G, and the blood pressure measuring device A transmits the collected blood pressure data to the transmission module 300 in the wearable device F via Bluetooth Low Energy (BLE). That is, the data transmission flow I uses the BLE method. The transmission module 300 in the wearable device F worn by the patient in the mobile monitoring device can communicate with H (i.e., the target device 500) via Near Field Communication (NFC) and / or Wireless Medical Telemetry System (WMTS), which corresponds to the data transmission flow J. In one implementation, the transmission module 300 in wearable device F transmits channel configuration information about the Wireless Medical Telemetry System (WMTS) to H (i.e., target device 500) via near-field communication methods such as Bluetooth. Based on this channel configuration information, the transmission module 300 or H (i.e., target device 500) in wearable device F is configured to establish a first communication channel between the transmission module 300 in wearable device F and H (i.e., target device 500), that is, to establish a wireless medical telemetry system communication channel. Based on the transmission power, physiological data information is transmitted between the transmission module 300 in wearable device F and H (i.e., target device 500) through the wireless medical telemetry system communication channel. The transmission signal on the wireless medical telemetry system communication channel between the transmission module 300 in wearable device F and H (i.e., target device 500) is detected, and the relevant distance is determined based on the detected transmission signal and the types of vital sign signals acquired by the monitoring modules 100 (A, B, C, D, E) to determine the transmission power.

[0072] Specifically, taking the acquisition of a vital sign signal by at least one monitoring module 100 as an example, such as... Figure 3 As shown, the workflow of the vital signs monitoring and transmission system of this application is as follows: S100: The monitoring module 100 monitors vital signs signals according to the monitoring time cycle and transmits the vital signs signals to the processing module 200; If the monitoring module 100 does not receive an abnormal signal from the processing module 200, it proceeds to S110; if the monitoring module 100 receives an abnormal signal from the processing module 200, it proceeds to S120. S110: Monitor according to the first monitoring cycle; S120: Monitor according to the second monitoring cycle; S200: The processing module 200 converts vital sign signals into physiological data information and determines whether the vital sign signals are normal; In step S200, if the processing module 200 determines that the vital signs signal is normal, it proceeds to S210; if the processing module 200 determines that the vital signs signal is abnormal, it proceeds to S220. S210: Detect the transmission distance between the transmission module 300 and the target device 500 according to the first detection cycle; S220: Send the abnormal signal to the monitoring module 100 and the transmission module 300, and detect the transmission distance between the transmission module 300 and the target device 500 according to the second detection cycle; S300: The transmission module 300 dynamically adjusts the transmission power based on the physiological data information transmitted by the processing module 200 and the transmission distance; In step S300, if the transmission module 300 does not receive a vital signs abnormality signal, it proceeds to S310; if the transmission module 300 receives a vital signs abnormality signal, it proceeds to S320. S310: The transmission module 300 determines the transmission power level based on the transmission distance, and adds a power increment corresponding to the vital sign category to the level. The power increment is selected as the first increment. Then, the transmission module 300 sends the physiological data information to the target device 500 according to the determined transmission power and the first transmission cycle. S320: The transmission module 300 determines the transmission power level based on the transmission distance, adds a power increment corresponding to the vital sign category to the level, wherein the power increment is selected as the second increment, and then the transmission module 300 sends the physiological data information to the target device 500 according to the determined transmission power and the second transmission cycle.

[0073] According to a preferred embodiment, the system includes a verification device for data verification. The verification device acquires transmitted data sent by the transmission module 300 and received data received by the target device 500 from the transmission module 300 via a wired connection. The verification device determines whether any data received by the target device 500 is missing by comparing and analyzing the differences between the transmitted data and the received data.
