[0001] The present application relates to the technical field of medical devices, in particular to a vital sign monitoring and transmission system. BACKGROUND

[0002] With the rapid development of wireless sensor network technology, wireless sensor network is applied more and more widely in life. Wireless sensor network is an application-oriented network system close to the objective physical world, and its generation and development have always been related to application. For many years, different field researchers have deduced that the application of WSN technology in the fields of military, fine agriculture, security monitoring, environmental monitoring, construction, industrial monitoring, intelligent transportation, logistics management, free space exploration, smart home, medical care, etc. has been fully affirmed and demonstrated. Among them, in the field of medical care, the patient's vital sign data obtained by the patient's position monitoring instrument based on wireless sensor network technology can be wirelessly and remotely transmitted to the device of the medical staff, so that the medical staff can monitor the patient's vital signs at any time, in order to monitor the patient's condition and provide effective clinical diagnosis basis for medical staff.

[0003] The prior art such as the patent document with publication number CN105769147A proposes a vital sign monitoring device and vital sign monitoring method. The vital sign monitor is integrated on the bracelet. The vital sign monitor includes a vital sign detection module, a single-chip microcomputer, an A / D converter, a buzzer, and a sending module. The single-chip microcomputer is connected with the vital sign detection module, the A / D converter, the buzzer, and the sending module respectively. The vital sign detection module is used to obtain vital sign data. The bracelet integrates the vital sign monitor, which is convenient for the monitored person to wear and monitor data in real time, such as monitoring body temperature, pulse, and blood oxygen saturation data. The data is sent to the mobile phone, and the mobile phone sends the data to the cloud server to realize real-time control of human health.

[0004] The prior art such as the patent document with publication number CN115005828A proposes a vital sign monitoring method and vital sign monitoring system. The vital sign monitoring system includes a vital sign acquisition device, a signal relay device, and a signal analysis device. The vital sign monitoring method includes: the vital sign acquisition device acquires a plurality of vital sign signals of a corresponding part of a human body, processes the plurality of vital sign signals to generate transmission data, and wirelessly transmits the transmission data to the signal relay device; the signal relay device receives the transmission data sent by the vital sign acquisition device, processes the received transmission data to acquire the plurality of vital sign signals, and transmits the plurality of vital sign signals to the signal analysis device; the signal analysis device receives the plurality of vital sign signals and processes the plurality of vital sign signals to acquire a plurality of target vital sign signals, and processes the plurality of target vital sign signals to acquire a vital sign signal analysis result.

[0005] The prior art such as the patent document with publication number CN112137579A proposes a signal transmission processing method of a mobile monitoring device, which comprises: obtaining at least one vital sign parameter signal of a patient by using at least one measurement sensor, wherein the measurement sensor can be attached to the 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 working 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 working power according to the distance; transmitting the physiological data information on the communication channel between the target device and the communication device based on the second working power, wherein the second working power is different from the first working power.

[0006] In the prior art, when the monitor transmits data in a wireless transmission mode, it is usually limited by the transmission distance. When the distance between the patient and the data analysis device exceeds a certain distance, the data analysis device cannot receive the data or receives incomplete data, resulting in data loss. The method of increasing the transmission power of wireless transmission data is usually used to solve the limitation of transmission distance, but the increased transmission power of the monitor will become interference noise, which will seriously affect the working state of other medical devices. In addition, there are certain defects in adjusting the power of data transmission only by distance, for example, when the amount of data to be transmitted increases, only the transmission power required by the distance is increased, or in the case where the amount of data to be transmitted increases while the distance decreases, the transmission power will be reduced according to the prior art solution, resulting in an increase in the time required for data transmission, which is not conducive to obtaining abnormal data information in a timely manner when the patient's vital signs are abnormal. Moreover, real-time detection of distance changes to dynamically adjust transmission power results in high computing power and power consumption, resulting in short working time, especially for miniature monitoring devices that rely on battery power.

[0007] In addition, on the one hand, there are differences in understanding among those skilled in the art, and on the other hand, the inventors have studied a large number of literatures and patents when making the invention, but due to the limited space, all the details and contents are not listed in detail, which does not mean that the invention does not have these characteristics of the prior art. On the contrary, the invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0008] In view of the deficiencies of the technical solutions proposed by the prior art, the present application proposes a system capable of monitoring vital signs and transmitting vital sign signals to a target device, aiming to solve the problems of inaccurate transmission power adjustment and short working time caused by high energy consumption of transmission distance detection in the prior art.

[0011] 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 updated according to the detection time period and the at least one vital sign signal.

[0012] According to a preferred embodiment, the processing module is capable of switching between a first detection period and a second detection period at least based on the vital sign signal when detecting the distance between the transmission module and the target device, wherein the processing module detects the transmission distance between the transmission module and the target device based on the first detection period when the vital sign signal is stable, and the processing module detects the transmission distance between the transmission module and the target device based on the second detection period when the vital sign signal is mutated.

[0013] According to a preferred embodiment, when the processing module processes multiple vital sign signals, the processing module switches all the first detection periods to the second detection period in the case that one of the vital sign signals is mutated, wherein the first detection period is greater than the second detection period.

[0014] According to a preferred embodiment, the processing module is capable of detecting the transmission distance between the transmission module and the target device at least in a measurement manner within the detection time period, wherein the measurement manner means that the processing module acquires the physical distance between the transmission module and the target device by a ranging method, and the processing module characterizes the transmission distance by using the physical distance.

[0015] According to a preferred embodiment, the processing module is further capable of detecting the transmission distance between the transmission module and the target device at least in a calibration manner within the detection time period, wherein the calibration manner means that the processing module characterizes the transmission distance based on the channel attribute quality between the transmission module and the target device for signal transmission.

[0016] According to a preferred embodiment, the transmission module determines the transmission power based on the transmission distance and / or the vital sign signal, wherein the transmission power is at least linearly related to the variation of the transmission distance; and the transmission power is at least related to the category of the vital sign signal.

[0017] According to a preferred embodiment, the transmission module is capable of pre-setting a plurality of power levels according to the variation of the transmission distance, and the transmission module determines the power level of the transmission power based on the transmission distance and / or the variation of the transmission distance fed back by the processing module.

[0018] According to a preferred embodiment, the transmission module is capable of pre-setting a plurality of corresponding power increments based on the category and / or state of the vital sign signal, and the transmission module increases the corresponding power increment on the current power level of the transmission power based on the vital sign signal fed back by the monitoring module. The category of the vital sign signal can be the pulse frequency, breathing frequency, heartbeat, body temperature and / or blood pressure of the patient, etc.; and the state of the vital sign signal refers to the normal state and abnormal state, i.e. the stable state and the mutation state.

For example, the detection time periods of the application are at least divided into a first detection period and a second detection period, and the processing module can detect the distance between the transmission module and the target device at least according to the first detection period and / or the second detection period. The first detection period of the processing module is greater than the second detection period, thereby increasing the time interval of the processing module detecting the transmission distance under the first detection period, so that the power consumed by the processing module for distance detection in the same period is reduced. Further, the distance detection power of the processing module under the first detection period is less than that under the second detection period, thereby further reducing the power consumed by the processing module for distance detection under the first detection period. In combination with the above two modes, the power consumed by the processing module for distance detection can be greatly saved, thereby prolonging the continuous working time of the micro monitoring device.

[0028] The application will be described in detail below in combination with the drawings.

[0029] Embodiment 1

[0030] Figure 1 A logic relationship diagram between various modules of a vital sign monitoring transmission system of the present application is shown, 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 transmissible physiological data information; and a transmission module 300 for transmitting the transmissible physiological data information converted by the processing module 200 to a target device 500.

[0031] According to a preferred embodiment, the processing module 200 is configured to determine a detection time period for detecting the distance between the transmission module 300 and the target device 500 according to the at least one vital sign signal and a preset rule.

[0032] For the prior art, the prior art proposes to dynamically adjust the transmission power by real-time detection of the distance change to solve the problem that the existing monitor is limited by the transmission distance when transmitting data in a wireless transmission manner, and usually uses the method of strengthening the transmission power of the wireless transmission data to solve the limitation of the transmission distance, but the strengthened transmission power of the monitor will become interference noise, which seriously affects the working state of other medical equipment. However, the scheme of the prior art to dynamically adjust the transmission power by real-time detection of the distance change will cause an increase in power consumption, especially for a miniature monitoring device 400 relying on battery power supply, the single working time of which depends on the duration that the battery can last. In other words, for the same miniature monitoring device 400, the more power it consumes per unit time, the shorter the time it can work.

[0033] Based on the above defects, the present application proposes a design of detecting the distance between the transmission module 300 and the target device 500 according to different detection time periods in different cases. For example, the detection time periods of the present application are at least divided into a first detection period and a second detection period, and the processing module 200 can detect the distance between the transmission module 300 and the target device 500 according to the first detection period and / or the second detection period. The first detection period of the processing module 200 is greater than the second detection period, thereby increasing the time interval of the processing module 200 detecting the transmission distance in the first detection period, reducing the power consumption of the processing module 200 for distance detection in the same period, and further reducing the distance detection power of the processing module 200 in the first detection period, thereby further reducing the power consumption of the processing module 200 for distance detection in the first detection period. In combination with the above two methods, the power consumption of the processing module 200 for distance detection can be greatly saved, thereby prolonging the continuous working time of the micro monitoring device 400.

[0034] Preferably, the first detection period and the second detection period can be designed in the above manner, thanks to the processing module 200 being able to confirm the detection time period for detecting the distance between the transmission module 300 and the target device 500 according to at least one vital sign signal according to a preset rule.

[0035] Preferably, the so-called preset rule means that the processing module 200 can switch between the first detection period and the second detection period based on at least one vital sign signal when detecting the distance between the transmission module 300 and the target device 500. When the vital sign 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 period. When the vital sign signal is mutated, the processing module 200 detects the transmission distance between the transmission module 300 and the target device 500 based on the second detection period.

[0036] Specifically, when the vital sign signal is stable, the data to be transmitted is not urgent, and the requirement for the transmission distance is relatively loose, so the time interval of distance detection can be prolonged, and the detection power of distance detection can be reduced. When the vital sign signal is mutated or abnormally fluctuates, the data needs to be transmitted to the target device 500 of the medical staff as soon as possible, and the transmission quality needs to be fully guaranteed, so the current transmission distance needs to be calculated as soon as possible in order to adjust the appropriate transmission power of the transmission module 300, so as to avoid the problem of slow transmission or even loss of transmission data due to the inadaptability of transmission power and transmission distance.

[0037] Preferably, when the processing module 200 processes multiple vital signs signals, the processing module 200 switches all the first detection periods to the second detection period in the case of a mutation in one of the vital signs signals, wherein the first detection period is greater than the second detection period. Specifically, the monitoring module 100 can acquire at least one vital sign signal, and can also acquire multiple vital signs signals. More specifically, the vital sign signals can be the number of patient pulses, the respiratory rate, the heartbeat, the body temperature, and / or the blood pressure, etc.

[0038] Preferably, the processing module 200 can at least detect the transmission distance between the transmission module 300 and the target device 500 in a detection time period in a measurement manner, wherein the measurement manner means that the processing module 200 acquires the physical distance between the transmission module 300 and the target device 500 by a ranging method, and the processing module 200 uses the physical distance to represent the transmission distance.

[0039] Specifically, the measurement manner of the physical distance at least includes an infrared ranging method, a microwave ranging method, or a method of measuring the distance on a GPS positioning map, i.e., displaying the position of the target device 500 on the map and the position of the patient wearing the communication device on the map to obtain the physical distance between the two, etc.

[0040] Preferably, the processing module 200 can at least detect the transmission distance between the transmission module 300 and the target device 500 in a detection time period in a calibration manner, wherein the calibration manner means that the processing module 200 represents the transmission distance based on the channel attribute quality between the transmission module 300 and the target device 500 for signal transmission.

[0041] Preferably, the calibration manner specifically means that the processing module 200 detects the transmission signal on the communication channel between the target device 500 and the communication device, determines the channel attribute quality on the communication channel based on the detected transmission signal, and determines the transmission distance according to the channel attribute quality, for example, determining the transmission distance according to the channel attribute quality can be based on the change relationship between the channel attribute quality and the transmission distance to determine the transmission distance according to the channel attribute quality. For example, the channel attribute quality becomes worse, which means that the transmission distance between the patient wearing the communication device and the target device 500 becomes larger; the channel attribute quality becomes better, which means that the transmission distance between the patient wearing the communication device and the target device 500 becomes smaller. Therefore, the change of the transmission distance can be obtained based on the change of the channel attribute quality according to the change relationship between the channel attribute quality and the transmission distance, so as to determine the transmission distance according to the channel attribute quality.

[0042] Preferably, the processing module 200 evaluates the channel attribute quality based on one or more of the following parameters:

[0043] a signal strength when the transmission module 300 transmits data to the target device 500;

[0044] a signal-to-noise ratio when the transmission module 300 transmits data to the target device 500;

[0045] a packet loss rate when the transmission module 300 transmits data to the target device 500.

[0046] Specifically, the channel attribute quality can deteriorate, which can be a decrease in signal strength, a decrease in signal-to-noise ratio, and / or an increase in packet loss rate, or vice versa. Of course, the channel attribute quality on the communication channel can also be evaluated and determined based on at least two factors or three factors of the above-mentioned signal strength, signal-to-noise ratio, and packet loss rate, so as to determine the distance change between the target device 500 and the communication device.

[0047] Preferably, the distance detection in the first detection period and the second detection period can be one or more of a measurement manner and a calibration manner. The distance detection power in the measurement manner specifically refers to the above-mentioned infrared emission power, microwave emission power, etc. in the infrared ranging, microwave ranging manner, etc. The distance detection power in the calibration manner specifically refers to the power of the transmitted detection signal.

[0048] Embodiment 2

[0049] This embodiment is an improvement and supplement based on embodiment 1, and the repeated content will not be described again.

[0050] Figure 1 A logical relationship diagram between various modules of a vital sign monitoring transmission system of the present application is shown, 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 physiological data information capable of being transmitted; and a transmission module 300 for transmitting the physiological data information capable of being transmitted converted by the processing module 200 to a target device 500.

[0051] According to a preferred embodiment, the transmission module 300 is configured to determine a transmission power for transmitting the physiological data information to the target device 500 based on the transmission distance between the transmission module 300 and the target device 500 updated according to the detection time period and the at least one vital sign signal.

[0052] There is prior art that adjusts the transmission power of the transmission module 300 according to the transmission distance. However, there are certain defects in adjusting the power of data transmission only by distance. For example, when the amount of data to be transmitted increases, only the transmission power required by the distance increases, or in the case where the amount of data to be transmitted increases while the distance decreases, the transmission power according to the prior art solution will decrease, resulting in an increase in the time required for data transmission. When the patient's vital signs are abnormal, it is not conducive to obtaining abnormal data information in a timely manner.

[0053] Based on the above defects, the present application proposes a technical solution that determines the transmission power in combination with the transmission distance and the vital sign signal, avoiding the problem that when the detected distance is small, the power is automatically adjusted to low power, but at this time a large amount of data or even emergency data needs to be transmitted, and due to the low power, the data transmission is not timely or data transmission is lost. In the technical solution of the present application, the gear of the transmission power is also linearly related to the transmission distance, but in addition to the adjustment of the gear of the transmission power, the present application also designs a corresponding power increment according to the type of the vital sign signal. Furthermore, the transmission module 300 adjusts the gear according to the transmission distance, and adds the power increment set according to the vital sign signal in the case where the gear of the transmission power is determined, thereby ensuring that the data can be completely transmitted.

[0054] Preferably, the transmission power determined by the transmission module 300 based on the transmission distance and / or the vital sign signal is dynamic, wherein the transmission power is at least linearly related to the change amount of the transmission distance; the transmission power is at least related to the category of the vital sign signal.

[0055] Preferably, the at least linearly related to the change amount of the transmission distance means that the transmission module 300 can at least pre-set a plurality of power gears according to the change amount of the transmission distance, and then the transmission module 300 determines the gear of the transmission power based on the transmission distance and / or the change amount of the transmission distance fed back by the processing module 200.

[0056] Specifically, the transmission module 300 can determine the specific size of the transmission power according to the change amount or change condition of the distance, for example, the transmission distance is linearly related to the working power, and the transmission module 300 adjusts the transmission power step by step according to the pre-set step segmentation number or segmentation amount based on the change amount or change condition of the transmission distance. In actual use, the channel attribute quality of the transmission data between the transmission module 300 and the target device 500 will be poor, indicating that the transmission distance between the patient wearing the communication device and the target device 500 is large, and then the transmission module 300 adjusts the transmission power to a larger power according to the transmission distance; the channel attribute quality will also be good, indicating that the distance between the transmission module 300 and the target device 500 is small, and then the transmission module 300 adjusts the transmission power to a smaller power according to the transmission distance. More specifically, taking the distance between the transmission module 300 and the target device 500 as an example, the distance changes within 100m, and a plurality of positions can be set according to the distance, for example, segmented by 20m, and one position is added every 20m, and the power of each position is increased by the same amount; for example, four positions are set at 0-10m, 10-30m, 30-60m, and 60-100m, respectively, and the power of each position is increased by one, two, three, and four, respectively.

[0057] Preferably, the transmission module 300 can pre-set a plurality of corresponding power increments based on at least the type and / or state of the vital sign signal, and then the transmission module 300 increases the corresponding power increment based on the transmission power of the current position of the vital sign signal fed back by the monitoring module 100. The type of vital sign signal can be the pulse frequency, breathing frequency, heartbeat, body temperature, and / or blood pressure of the patient; and the state of the vital sign signal refers to the normal state and abnormal state, i.e., the stable state and the mutation state.

[0058] Preferably, the transmission module 300 sets the power increment according to the type of vital sign signal, which means that for each different type of vital sign signal, the data amount after being converted into physiological data information can not be consistent, taking body temperature and heartbeat as an example, the change of body temperature in a short time is low, while the heartbeat is moving in a short time, so the size of the physiological data information obtained by the body temperature and the heartbeat is not necessarily the same, and usually different, and thus the power required for transmitting the physiological data information is also not the same, so the power increment corresponding to the body temperature and the heartbeat is also not the same.

[0059] Preferably, the transmission module 300 sets the power increment according to the type of vital sign signal, that is, for the same vital sign signal, it has at least two states, normal state and abnormal state, and for the same vital sign signal, the power increment includes at least a first increment and a second increment, the first increment is slightly less than the second increment, wherein 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 vital sign signal, the information data of the abnormal state is more urgent and necessary, so more power needs to be added on the basis of the same transmission power level to leave enough surplus power to transmit the abnormal state information, avoiding the problem of not timely or missing transmission of abnormal information.

[0060] Preferably, the transmission module 300 can at least adjust the transmission time period based on the transmission distance and the vital sign signal, and the transmission time period is dynamically adjusted based on the change amount of the transmission distance and the type and / or state of the vital sign signal.

[0061] 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 greater than the second transmission period, and the transmission module 300 selects the first transmission period or the second transmission period for transmission of physiological data information according to whether the vital sign signal fed back by the processing module 200 is abnormal.

[0062] Specifically, when the processing module 200 feeds back that the vital sign signal is stable, the transmission module 300 transmits physiological data information based on the first transmission period according to the corresponding transmission power (including power level and power increment), and the first transmission period has a longer time interval than the second transmission period, so that the transmission module 300 consumes less power in the first transmission period, which helps to prolong the endurance of the micro monitoring device 400.

[0063] Specifically, when the processing module 200 feeds back that the vital sign signal is abnormal, the transmission module 300 transmits physiological data information based on the second transmission period according to the corresponding transmission power (including power level and power increment), and the second transmission period has a shorter time interval than the first transmission period, so that the transmission module 300 can send physiological data information at a faster frequency in the second transmission period, which helps medical staff to discover abnormalities in patients in a timely manner.

[0064] In the present application, the monitoring time period, the detection time period and the transmission time period can be the same or different. Specifically, the monitoring time period refers to the monitoring module 100 monitoring the vital sign signal of the corresponding body part of the human body according to the monitoring time period, in other words, the monitoring module 100 monitors the vital sign signal according to the time interval under 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 interval under 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 interval under the transmission time period.

[0067] According to a preferred embodiment, the monitoring module 100 can be attached to the relevant part of the patient's body to acquire the vital sign signal at that part of the patient.

[0068] Preferably, in the present embodiment, the at least one monitoring module 100 can be a sensor or the like for measuring the patient's pulse frequency, respiratory rate, heartbeat, body temperature and / or blood pressure, respectively.

[0069] Specifically, the monitoring module 100 corresponding to measuring the pulse can be attached to the wrist or finger of the patient or the like.

[0070] Specifically, the monitoring module 100 for measuring the respiratory rate can be attached to the relevant position of the patient's chest, such as near the heart, using an electrocardiogram sensor to measure the respiratory rate using impedance respiration.

[0071] Specifically, the monitoring module 100 for measuring the body temperature can be attached to the axillary, oral cavity or anus of the patient or the like.

[0072] Specifically, the monitoring module 100 for measuring blood pressure can be attached to the arm of the patient, for example, the monitoring module 100 for measuring blood pressure can employ a photoelectric sensor, or employ a combination of air pump and cuff, and use the combination to perform blood pressure inflation measurement or blood pressure deflation measurement to obtain blood pressure values.

[0073] Specifically, the monitoring module 100 for measuring heartbeat can be attached to the relevant position of the chest of the patient, such as the vicinity of the heart, and the specific attachment position can be adjusted according to actual conditions, which is not limited here.

[0074] Preferably, the 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, and the final vital sign parameter signal can be recorded in digital form or in graphical form, which is not limited here.

[0075] Preferably, the target device 500 is physically separated from the mobile monitoring device, and is two independent devices.
