Description

Technical Field

[0001] This invention relates to the field of health management technology, and in particular to a method, system, and smart water cup for collecting vital sign data based on a smart water cup. Background Technology

[0002] With increasing health awareness, smart wearable health devices, such as smart bracelets and watches, are becoming increasingly popular. However, these devices have significant drawbacks: low monitoring accuracy; being located on the wrist, the extremity of blood flow, they are easily affected by environmental and movement interference, leading to discrepancies between measured data such as heart rate and core physiological parameters; requiring active and prolonged wear by the user, which may cause skin discomfort; and limited battery life necessitates frequent charging, interrupting continuous monitoring; their data acquisition dimensions are relatively limited, unable to penetrate the skin barrier to obtain key biochemical markers in bodily fluids such as saliva, resulting in insufficient information comprehensiveness. In contrast, while blood monitoring is the gold standard, it requires invasive procedures, and subcutaneous tissue monitoring carries the risk of infection. Summary of the Invention

[0003] The main objective of this invention is to provide a method, system, and smart water cup for collecting vital sign data, aiming to collect high-quality, highly consistent, and long-term comparable effective vital sign data without being noticed.

[0004] To achieve the above objectives, this invention proposes a method for collecting vital sign data based on a smart water cup. The smart water cup includes a straw, a main controller, and a sensor acquisition module, a saliva sample analysis module, and a wireless communication module electrically connected to the main controller. The sensor acquisition module is located at the end of the straw near the mouthpiece and includes a pressure sensor, a temperature sensor, an optical sensor, a bioimpedance sensor, and an acceleration sensor. The saliva sample analysis module includes a suction unit, a filtering unit, and a detection unit. S100, in response to the pressure sensor detecting the negative pressure generated by the user's sucking, the main controller outputs a collection trigger signal to enable the main controller to start a collection window for a preset collection duration; and, at each preset time interval, the main controller activates the suction unit to collect a portion of the user's saliva, transports it to the filtering unit to filter out impurities, and then detects the presence or relative concentration of specific components in the saliva through the detection unit. S200, when the acquisition window is open, the main controller controls the temperature sensor, optical sensor and bioimpedance sensor to acquire vital sign data to characterize the user's oral cavity state, and controls the accelerometer to acquire acceleration data to characterize the user's movement state, so as to obtain the original set of vital sign data corresponding to the drinking session. S300, after the collection window ends, the main controller determines whether the drinking water meets the preset valid collection conditions based on the original vital sign data set, and only marks the original vital sign data set that meets the valid collection conditions as valid vital sign data, and stores it in association with the corresponding time information; S400, the effective vital sign data is sent to the mobile terminal through the wireless communication module, and the analysis engine set in the mobile terminal analyzes the effective vital sign data and generates a health report.

[0005] In one possible implementation, after step S200, the method further includes: S210, when the temperature sensor detects a sudden change in reading caused by the liquid passing through the straw, the main controller immediately forces the termination of the acquisition window; S220, the main controller intercepts part of the vital signs data collected before the sudden change in readings, and marks the remaining part of the vital signs data as invalid vital signs data.

[0006] In one possible implementation, after step S220, the method further includes: S230, based on the data obtained from the accelerometer, the main controller determines whether the user is in a stationary state and marks the set of raw vital signs data collected in a non-stationary state as invalid vital signs data.

[0007] In one possible implementation, after step S300, the method further includes: S310, at the end of the acquisition window, the main controller shuts off the power to at least some of the sensors except the pressure sensor and its power supply circuit, and the power to the wireless communication module to enter a low-power state, and restores power when the main controller outputs the acquisition trigger signal again.

[0008] In one possible implementation, after step S310, the method further includes: S320, when the acquisition window ends, the main controller immediately starts or resets an internal timer with a preset time interval threshold; S330, if the user drinks water again before the time interval threshold is reached, steps S100 to S300 are still executed, but the collected vital signs data will be marked as invalid vital signs data.

[0009] In one possible implementation, in step S100, the preset acquisition duration of the acquisition window is set to between 300 and 800 milliseconds.

[0010] This application also proposes a vital signs data acquisition system, including: The detection and activation module is used to respond to the negative pressure generated by the user's sucking detected by the pressure sensor. The main controller outputs a collection trigger signal to enable the main controller to start a collection window for a preset collection duration. At each preset time interval, the main controller activates the suction unit to collect a portion of the user's saliva, which is then transported to the filtering unit to remove impurities. The detection unit then detects the presence or relative concentration of specific components in the saliva. The data set module is used to control the temperature sensor, optical sensor and bioimpedance sensor to collect vital sign data to characterize the user's oral cavity status within the acquisition window, and to control the accelerometer to collect acceleration data to characterize the user's movement status, so as to obtain the raw vital sign data set corresponding to the drinking session. The storage module is used to determine whether the drinking time meets the preset valid collection conditions based on the original vital sign data set when the collection window ends, and only the original vital sign data set that meets the valid collection conditions is marked as valid vital sign data and stored in association with the corresponding time information. The analysis report module is used to send valid vital sign data to the mobile terminal via the wireless communication module. The analysis engine set in the mobile terminal analyzes the valid vital sign data and generates a health report.

[0011] This application also proposes a smart water cup, including a cup body, a straw, a sensor acquisition module, and a saliva sample analysis module: The saliva sample analysis module includes an aspiration unit, a filtering unit, and a detection unit; The cup body is equipped with a main controller and a wireless communication module, as well as the filtering unit and the detection unit; The sensor acquisition module is located at the end of the straw near the drinking mouthpiece, and the vital sign acquisition module includes at least one or more of the following: pressure sensor, temperature sensor, optical sensor, bioimpedance sensor, and acceleration sensor. The main controller is electrically connected to the sensor acquisition module, the saliva sample analysis module, and the wireless communication module, respectively, wherein: The pressure sensor is used to output a data acquisition trigger signal to the main controller when it detects negative pressure generated by the user's sucking. The main controller is configured to: upon responding to the acquisition trigger signal, open an acquisition window for a preset acquisition duration, acquire vital sign data from the temperature sensor, optical sensor, and bioimpedance sensor in parallel within the acquisition window, store the vital sign data along with a timestamp after the acquisition window ends, and shut down the power supply to at least some sensors except the pressure sensor and its power supply circuit and the wireless communication module outside the acquisition window to enter a low-power state; and at each preset time interval, the main controller activates the aspiration unit to collect a portion of the user's saliva, transports it to the filtration unit to filter out impurities, and then detects the presence or relative concentration of specific components in the saliva through the detection unit. The wireless communication module is used to send the vital sign data to the mobile terminal under the control of the main controller.

[0012] This invention employs a synergistic mechanism of suction negative pressure triggering and liquid arrival sensing, setting a collection window of 300-800 milliseconds to ensure that bioimpedance signals are collected in a pure state uncontaminated by liquid. Through motion state screening and forced silent period judgment based on physiological recovery cycles, a multi-level, intelligent data quality control system is constructed, effectively eliminating interference from motion artifacts and physiological instability caused by frequent water intake. This successfully achieves the collection of high-quality, highly consistent, and long-term comparable vital sign data without the user's awareness, laying a solid data foundation for generating reliable personal health trend reports.

[0016] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] Reference Figure 1 This invention proposes a method for collecting vital sign data based on a smart water cup. The smart water cup includes a straw, a main controller, and a sensor acquisition module, a saliva sample analysis module, and a wireless communication module electrically connected to the main controller. The sensor acquisition module is located at the end of the straw near the mouthpiece and includes a pressure sensor, a temperature sensor, an optical sensor, a bioimpedance sensor, and an acceleration sensor. The saliva sample analysis module includes a suction unit, a filtering unit, and a detection unit. The invention is characterized by including: S100, in response to the pressure sensor detecting the negative pressure generated by the user's sucking, the main controller outputs a collection trigger signal to enable the main controller to start a collection window for a continuously preset collection duration; and, at every preset time interval, the main controller starts the suction unit to collect a portion of the user's saliva, transports it to the filter unit to filter out impurities, and then detects the presence or relative concentration of specific components in the saliva through the detection unit. S200: When the acquisition window is open, the main controller controls the temperature sensor, optical sensor and bioimpedance sensor to acquire vital sign data to characterize the user's oral cavity state, and controls the accelerometer to acquire acceleration data to characterize the user's movement state, so as to obtain the original set of vital sign data corresponding to the drinking session. S300: After the collection window ends, the main controller determines whether the drinking water meets the preset valid collection conditions based on the original vital sign data set, and only marks the original vital sign data set that meets the valid collection conditions as valid vital sign data, and stores it in association with the corresponding time information; The S400 transmits valid vital sign data to a mobile terminal via a wireless communication module. The analysis engine located in the mobile terminal then analyzes the valid vital sign data and generates a health report.

[0019] Understandably, the smart water cup of this application triggers multiple sensors through the sucking action when drinking water, quickly collecting state data of the user's mouth and body, thereby monitoring health trends in a long-term and imperceptible manner. The straw and pressure sensor act as the starting switch for the entire process. It detects the negative pressure generated by the sucking action, triggering and initiating the timing of the data acquisition window, thus determining the start of a drinking action. The temperature sensor is located at the top of the inner wall of the mouthpiece, preferentially contacting the upper lip or tongue during the window period to achieve instantaneous measurement of near-core body temperature. This data serves as an indicator for assessing metabolism, immunity, and circadian rhythms. In this case, the optical sensor is a photoplethysmography (PPG) sensor, embedded in the surface below the mouthpiece and close to the cup body, ensuring a tight fit with the lower lip. Using PPG, it rapidly captures hemodynamic signals during operation to extract heart rate and heart rate variability, which are neurological indicators for assessing energy load, fatigue, and stress levels. The bioimpedance sensor has at least one pair of microelectrodes on the inner and outer walls of the mouthpiece. During the window period, it measures the impedance characteristics of saliva or mucous membranes, serving as a core basis for inferring cellular hydration and electrolyte balance.

[0020] The saliva sample analysis module and the sensor acquisition module operate independently. The saliva sample analysis module can be started via a separate button. During non-drinking periods, the aspiration unit uses negative pressure generated by a micro-electromagnetic pump to actively draw in and store a micro-quantitative saliva sample from a dedicated inlet at the spout of the water cup. The filtration unit separates impurities from the stored saliva sample through a filter membrane before measurement, and then introduces it into a sealed chamber equipped with a detection unit for testing. For example, by detecting the rise in melatonin before bedtime each day, the short-term or long-term circadian rhythm can be assessed, or by analyzing cortisol concentration at a fixed time each day, the short-term or long-term stress load can be assessed. Furthermore, after the measurement is completed, the measured sample can be discharged into a preset waste liquid tank, and the detection chamber and flow channel can be rinsed with clean water or buffer solution.

[0021] S100 is the trigger phase. When the user sucks on the straw, the pressure sensor detects a negative pressure signal, the main controller is activated, and a preset data acquisition window is opened. This ensures that each data acquisition is performed within a standardized time range. In this example, the window duration is 500 milliseconds. This time is sufficient to complete one data acquisition, but shorter than the time required for the liquid to be drawn from the bottom of the cup to the sensor position. Since the working principle of temperature and bioimpedance sensors relies on the measurement of body tissue, if these sensors are covered by liquid, the signal transmission will be severely interfered with. The temperature and electrical properties of liquid are different from those of human tissue, which will lead to data distortion. Therefore, the window duration is set to ensure that all key vital sign data are acquired before the liquid reaches and contaminates the sensor.

[0022] S200 is the data acquisition phase. During the acquisition window and its duration, the main controller simultaneously directs multiple sensors to work. Temperature, optical, and bioimpedance sensors collect oral cavity vital signs data such as body temperature, heart rate, hydration status, and electrolyte balance. The accelerometer collects motion data to determine if the user is moving. All data is packaged into a raw vital signs data set corresponding to that drinking session. It should be noted that the optical sensor is also activated when the acquisition window is open. However, due to the special nature of the optical sensor, its acquisition time usually takes several seconds or even longer. Therefore, its working duration is calculated independently and does not end synchronously with the acquisition window. It will continue to acquire data for several seconds before closing and storing the data.

[0023] S300 is the screening and storage stage. After the collection window ends, the main controller will screen the batch of raw data to determine whether it meets the valid collection conditions. For example, whether the sucking time is too short, whether the data is too much due to movement, etc. The data that passes the screening will be marked as valid vital sign data and stored together with the timestamp. At the same time, the data detected by the saliva sample analysis module will also be saved.

[0024] S400 is the analysis and reporting stage. The cup is only responsible for collection and initial screening. The stored valid data and saliva sample analysis data are sent to the user's mobile terminal, such as a mobile phone or tablet, through the wireless communication module. The analysis engine in the APP on the terminal will conduct in-depth analysis of this long-term accumulated data. If abnormalities are found in the data, the APP will send intervention information to the user and finally generate a health report, providing health advice and risk warnings.

[0025] This embodiment, through the fusion analysis of multimodal physiological data, can identify various health states of users, including but not limited to hydration status, energy and fatigue status, neurological stress status, immune and inflammation levels, and sleep and recovery quality. Through the above steps, non-invasive data collection is achieved, integrating health monitoring into daily drinking activities without requiring active user cooperation, greatly improving compliance and data continuity. The oral cavity is located in the core area of ​​the body, allowing this embodiment to acquire near-core data in a natural manner, perfectly balancing information quality and ease of access. Simultaneous collection of physiological and behavioral data makes the analysis results more comprehensive and accurate. Long-term monitoring data depicts a user's unique health baseline, which is more valuable than a single physical examination.

[0026] Reference Figure 2 In one embodiment of the present invention, after step S200, the method further includes: S210, when the temperature sensor detects a sudden change in reading caused by the liquid passing through the straw, the main controller immediately forces the termination of the acquisition window. S220: The main controller intercepts part of the vital signs data collected before the sudden change in readings and marks the remaining part of the vital signs data as invalid vital signs data.

[0027] Understandably, the acquisition window can end naturally after a preset time, or via event-based intelligent termination by the S210. After the acquisition window opens, the temperature sensor continuously monitors the temperature. Since the liquid temperature inside the straw is usually different from the oral cavity temperature, when the liquid flows past the sensor, it causes a sudden change in the temperature reading. The main controller treats this temperature change as a termination signal and immediately forces the acquisition window to close. This method is much more accurate than a fixed time; regardless of the user's sucking force or the liquid viscosity, it can stop acquisition at the moment of liquid interference, ensuring data purity.

[0028] The S220 performs data interception and labeling. When the acquisition window is forcibly terminated, the main controller will truncate the valid segment of the raw data already acquired. This truncation includes all data collected by the temperature and bioimpedance sensors from the start of acquisition until the moment before the temperature abrupt change. The small amount of data acquired after the abrupt change is marked as invalid vital sign data, as this data is distorted due to liquid interference and has no analytical value. Data from the optical sensors, however, is acquired independently and can be collected and stored normally.

[0029] In one embodiment of the present invention, after step S220, the method further includes: S230, based on the data acquired from the accelerometer, the main controller determines whether the user is stationary and marks the raw vital signs data collected in a non-stationary state as invalid vital signs data.

[0030] Understandably, step S230 is a secondary screening based on motion state. The main controller calls the acceleration sensor data acquired in the acquisition window for analysis. By analyzing the amplitude, frequency and pattern of the acceleration data, the main controller can determine whether the user is in a stationary state or a moving state. If it is determined to be in a stationary state, the data continues to flow to the next step S300. If it is determined to be in a non-stationary state, the main controller will directly mark the vital sign data as invalid vital sign data.

[0031] Because both optical and bioimpedance sensors are highly sensitive to motion, muscle contractions and body swaying during movement can significantly interfere with the signals, leading to severely inaccurate measurements of heart rate and other vital signs. Vital signs measured at rest, such as resting heart rate, are the fundamental and comparable indicators for assessing health status. Measurements taken during exercise fluctuate greatly, limiting their relevance. By filtering out data from resting states, the system can construct a more stable and medically meaningful health baseline.

[0032] In one embodiment of the present invention, after step S300, the method further includes: S310, after the acquisition window ends, the main controller shuts off the power to at least some sensors and wireless communication modules except for the pressure sensor and its power supply circuit to enter a low-power state, and restores power when the main controller outputs the acquisition trigger signal again.

[0033] Understandably, the S310 aims to maximize battery life, ensuring the water bottle can remain in standby mode for extended periods between uses. After the data acquisition window ends, the main controller performs power management, actively shutting down the power to at least some of the temperature, optical, bioimpedance, accelerometer, and wireless communication modules. After disabling these high-power components, the entire system enters a "sleep" or "standby" mode, where only the pressure sensor and the minimum necessary circuitry to maintain the main controller's basic operation remain powered. This low-power state continues until the pressure sensor detects a sucking motion again, at which point the system is awakened and power is restored to all disabled sensors and modules, preparing for a new round of data acquisition.

[0034] One of the biggest challenges of smart wearable / portable devices is battery life. Optical sensors, bioimpedance sensors, and wireless communication modules are all power-intensive components. If they are left in standby mode, the battery will be depleted quickly. S310 in this embodiment solves this problem.

[0035] Reference Figure 3 In one embodiment of the present invention, after step S310, the method further includes: S320: When the acquisition window ends, the main controller immediately starts or resets an internal timer with a preset time interval threshold. S330: If the user drinks water again before reaching the time interval threshold, steps S100 to S300 will still be executed, but the collected vital signs data will be marked as invalid vital signs data.

[0036] Understandably, since the oral mucosal environment, including temperature, humidity, and saliva composition, requires sufficient time to recover to a stable physiological baseline after being physically and chemically disturbed by drinking, the main controller immediately starts or resets an internal timer at the end of a complete data acquisition cycle. This timer has a preset time interval threshold. If the pressure sensor detects the user's sucking behavior again before the timer reaches the threshold, the system will still execute the complete data acquisition cycle from S100 to S300. However, the main controller will forcibly mark this as invalid or reference data, and will not perform subsequent analysis by the analysis engine.

[0037] These two steps prevent data distortion caused by continuous and frequent water intake from the outset, ensuring that every data point used for long-term health analysis represents a stable and comparable physiological state, thereby greatly improving the accuracy and reliability of the system's judgment.

[0038] In one embodiment of the present invention, in step S100, the preset acquisition duration of the acquisition window is set to between 300 and 800 milliseconds.

[0039] Understandably, the acquisition window must end before the liquid reaches the sensor. The 300-800ms setting is a reasonable range based on measurements of the process from the lips touching the straw to the liquid flowing through the sensor; in this example, it is specifically set to 500ms.

[0040] Furthermore, 300-800ms is a time range far below the human perception threshold. It usually takes several seconds for a user to complete a sucking or drinking action. The system completes most of the data collection, judgment, and sleep preparation in a time that the user can hardly perceive, thus achieving the design goal of imperceptible monitoring.

[0041] This invention employs a synergistic mechanism of suction negative pressure triggering and liquid arrival sensing, precisely setting a collection window of 300-800 milliseconds to ensure that bioimpedance signals are collected in a pure state uncontaminated by liquid. Through motion state screening and forced silent period judgment based on physiological recovery cycles, a multi-level, intelligent data quality control system is constructed, effectively eliminating interference from motion artifacts and physiological instability caused by frequent water intake. This successfully achieves the collection of high-quality, highly consistent, and long-term comparable vital sign data without the user's awareness, laying a solid data foundation for generating reliable personal health trend reports.

[0042] This application also proposes a vital signs data acquisition system, including: The detection and activation module is used to respond to the negative pressure generated by the user's sucking detected by the pressure sensor. The main controller outputs a collection trigger signal to enable the main controller to start a collection window with a preset collection duration. At each preset time interval, the main controller activates the suction unit to collect a portion of the user's saliva, transports it to the filter unit to filter out impurities, and then detects the presence or relative concentration of specific components in the saliva through the detection unit. The data set module is used to control the temperature sensor, optical sensor and bioimpedance sensor to collect vital sign data to characterize the user's oral cavity state when the acquisition window is open, and to control the accelerometer to collect acceleration data to characterize the user's movement state, so as to obtain the raw vital sign data set corresponding to the drinking session. The storage module is used to determine whether the drinking water meets the preset valid collection conditions based on the original vital sign data set after the collection window ends. Only the original vital sign data set that meets the valid collection conditions is marked as valid vital sign data and stored in association with the corresponding time information. The analysis report module is used to send valid vital sign data to the mobile terminal via the wireless communication module. The analysis engine set in the mobile terminal analyzes the valid vital sign data and generates a health report.

[0043] This application also provides a smart water cup, including a cup body, a straw, a sensor acquisition module, and a saliva sample analysis module: The saliva sample analysis module includes an aspiration unit, a filtering unit, and a detection unit; The cup body is equipped with a main controller and a wireless communication module, as well as a filtering unit and a detection unit; The sensor acquisition module is located at the end of the straw near the drinking mouthpiece. The vital signs acquisition module includes at least one or more of the following: pressure sensor, temperature sensor, optical sensor, bioimpedance sensor, and acceleration sensor. The main controller is electrically connected to the sensor acquisition module, the saliva sample analysis module, and the wireless communication module, respectively, wherein: The pressure sensor is used to output a trigger signal to the main controller when it detects negative pressure generated by the user's sucking. The main controller is configured to: upon responding to a data acquisition trigger signal, open a data acquisition window for a preset duration, acquire vital sign data from the temperature sensor, optical sensor, and bioimpedance sensor in parallel within the acquisition window, store the vital sign data along with a timestamp after the acquisition window ends, and shut down the power supply to at least some sensors and the wireless communication module except for the pressure sensor and its power supply circuit outside the acquisition window to enter a low-power state; and at each preset time interval, the main controller activates the suction unit to collect a portion of the user's saliva, transports it to the filtering unit to filter out impurities, and then detects the presence or relative concentration of specific components in the saliva through the detection unit. The wireless communication module is used to send vital sign data to the mobile terminal under the control of the main controller; The drinking spout integrates a bioimpedance measurement electrode, a miniature temperature sensing probe, a PPG optical window, and a saliva sampling port for the aspiration unit; all of these are miniaturized components. The cup body houses a bioimpedance measurement circuit, a temperature signal processing circuit, a PPG signal processing circuit, as well as a miniature pump-valve system for the filtering and detection units, and a sealed detection chamber. These circuits are electrically connected to the corresponding probes in the drinking spout via flexible circuits or wires.

[0044] It should be noted that due to the special nature of optical sensors, they need to come into contact with the skin or mucous membranes to obtain accurate data. However, when a user drinks, there will be water flowing in their mouth, which will interfere with the readings of the optical sensor. Therefore, in this example, the optical sensor is placed on the lower side of the spout, close to the cup body, so that it will not enter the mouth when the user drinks, but will be located at the user's lower lip. This way, accurate data can be obtained without being interfered with by the water flow when drinking.

[0045] Since strong external light may penetrate the straw wall and interfere with the photodetector in the optical sensor, an optical sealing structure or modulation light source technology can be adopted as needed to make it emit light of a specific frequency and only detect the signal of that frequency, thus filtering out ambient light noise.
