Description

System and method for collecting and processing user health data

Technical Field

The present invention relates to the field of health technology, and more particularly, to a system and method for collecting and processing user health data.

Background

Along with the improvement of living standard and consumption standard of people, people pay more and more attention to their health. The oral health condition is an important aspect reflecting the health condition of a person, so the oral health condition is always paid attention by the health management department of China. National oral health epidemiological surveys have been conducted four times in 1983, 1995, 2005 and 2015 in China. The findings include a number of aspects of oral health epidemiology, including tooth brushing rates at various ages, daily tooth brushing times, fluoride-containing toothpaste usage, child caries status, and the like. However, such oral health epidemiological surveys typically rely only on school census, hospital clinical data, physical examination data, and even a portion of questionnaires. Such statistical surveys require a large amount of manpower and material resources, so that the number of samples is limited, and the accuracy and timeliness of data are affected.

On the other hand, in recent years, various types of health terminal devices for personal use by users have been developed on the market, and many of them are intelligentized to some extent, such as smart bracelets, smart watches, smart blood pressure meters, and the like. However, the current intelligent health terminal devices mainly focus on recording the exercise data of the user, such as the step number, the running speed and the exercise track, and part of the products can provide health reports or feedback for the user, but the health reports or feedback are mainly represented by the BMI index of the user and the heat consumed by the exercise. There is a lack of intelligent end products in the oral health field. Some so-called "intelligent toothbrushes" appearing in the market at present have intelligence that is generally embodied in detecting and reminding a user whether a brushing manner is standard, such as brushing strength, coverage, brushing times, etc., is appropriate, and do not collect and analyze oral health conditions of the user.

It would therefore be desirable to provide a solution that allows a wide range of user oral health data to be collected.

Detailed Description

The present invention will be described in detail below with reference to the attached drawings, and the features of the present invention will be further apparent from the following detailed description.

FIG. 1 is an exemplary architecture diagram of a user health data collection processing system, according to one embodiment of the present invention. As shown in fig. 1, the user health data collection processing system 100 may include a plurality of smart oral care products 102 for collecting user health data, and a data collection processing unit 104 communicatively coupled with the smart oral care products 102. Optionally, the user health data collection processing system 100 may also include a plurality of mobile computing devices 106, such as smartphones. As an example, the smart oral care product 102 may send the collected user health data directly to the cloud data collection processing unit 104 or via the mobile computing device 106 to the data collection processing unit 104.

As one example, the smart oral care product 102 may be a smart dental scaler (hereinafter "scaler") having data collection, storage, transmission, processing, etc. capabilities. The physical structure and internal functional structure of the smart oral care product 102 will be described in greater detail below in conjunction with fig. 2-4. The user health data that the smart oral care product 102 can collect includes various oral health data including, but not limited to, dental data, oral data, and brushing behavior data. Dental data may include, but is not limited to: tooth age, tooth size, tooth shape, distance between teeth, dental plaque, tooth number, caries condition, gingival bleeding level, tooth looseness, tooth sensitivity level, ultrasonic data of teeth, fluorescence data of teeth, and the like. Oral data may include, but is not limited to: saliva pH, saliva viscosity, tongue coating condition, oral ozone content, oral bacterial content and approximate composition, oral ulcer condition, pharyngeal condition, and the like. Brushing behavior data may include, but is not limited to: number of teeth brushed, time of teeth brushed per day, geographic location of teeth brushed per day, time spent brushing each time, intensity of teeth brushed, type of toothpaste, etc.

In addition to oral health data, the smart oral care product 102 may also collect facial health data outside of the oral cavity, including but not limited to: eye congestion, skin condition, lip chapping, etc., which may directly or indirectly reflect the health of the user.

In addition, the smart oral care product 102 may also collect health behavior data of the user including, but not limited to, body temperature, daily wake up time, daily go to bed time, and the like. Wherein the time to get up and time to go to bed can be approximated by the morning and evening brushing time, e.g. fitting based on statistics of brushing times for a large number of users, e.g. when the statistics show that most users brush their teeth within 5-15 minutes to get up, and get up (fall asleep after 30-60 minutes) within 5-10 minutes after brushing their teeth at night, people of different ages have different times to get up and times to fall asleep, it can be distinguished by classification and fitting whether this brushing corresponds to the time to get up or to brushing after a meal, e.g. a brushing activity that occurs for 30 minutes at 11 o' clock on weekend, for users over 60 years old it is more likely to be inferred to be brushing after lunch, and for users over 18-30 years old it is more likely to be inferred to be brushing after getting up.

The mobile computing device 106 may communicate with the smart oral care product 102 by wired or wireless means. In one example, the mobile computing device 106, upon receiving the collected user health data (e.g., the aforementioned oral health data, facial health data, health behavior data, etc.) from the smart oral care product 102, uploads the data to the cloud-based data collection processing unit 104. Further, the mobile computing device 106 may be bound with one or more smart oral care products 102. The mobile computing device 106 also collects user fill-in data from the user. For example, the user may provide basic information data of the user, including but not limited to age, gender, blood pressure, blood lipids, and other physical health data, through the mobile computing device 106. Additionally, the user may also upload health report data via the mobile computing device 106, including, but not limited to, dental CT photographs, dental panoramic photographs, physical examination reports, and other physical health reports provided by the medical facility, and may also include information to receive treatment, such as tooth washing, tooth filling, tooth implantation, and the like.

The data collection processing unit 104 may include one or more servers or data centers located in the cloud and may receive data collected by the smart oral care products 102 and user information data and statement-of-health data provided by the user via the mobile computing device 106 over a network. The data collection processing unit 104 may collate and convert the data into a unified data structure. As an example, various types of data are bound with user IDs representing respective users, sorted and stored according to a preset data structure. For example, one example data structure may be:

the structure-transformed data is available for further processing. As an example, the data collection processing unit 104 may capture relevant data from the database for data processing based on multiple dimensions of the user's age, gender, region, etc., for different points of interest (e.g., brushing times, caries condition, etc.), and generate data processing results for a group of users. As yet another example, for a single user, various aspects of the health data may be processed to generate a user representation for their individual, characterizing their health and behavior. For example, data processing may include statistics for particular data items, making decisions for certain health aspects, mining data using various big data, machine learning, etc. techniques to discover various factors that affect health, training various pre-trained models, and profiling users, information feedback, service recommendations, etc. based on the trained models. It is noted that, since the data collection terminal of the user health data collection processing system of the present invention is based on an intelligent oral care product, and the collection frequency of the data is usually one to two times per day or more, the data uploaded to the data collection processing unit has particularly good timeliness, so that various data processing for individual or group of users can be dynamically performed, accordingly, the processing result of the latest or any interested time period can be obtained, and the training efficiency and accuracy of various models can be effectively provided. More details regarding data processing will be described in further detail later in connection with fig. 5-6.

Furthermore, the results of the statistical analysis for the user population may then be used as a basis for the health judgment of the individual user. For example, if a certain health index of a user meeting a certain condition (e.g., age, sex) is mostly located in a certain interval, if the health index of a user meeting the same condition is not located in the interval, the health index can be determined as a health index needing attention, and a corresponding health suggestion can be provided for the health index.

Additionally, while the present invention is described in a configuration in which the data processing unit is illustrated as being located in the cloud and separate from the smart oral care product, those skilled in the art will appreciate that in some embodiments the data processing unit may be located locally or some of its functionality may be implemented by the smart oral care product or the mobile computing device or a combination of both. For example, for some simple health index judgment and information feedback, it is not necessary to complete through a cloud data processing unit, for example, some oral cavity data such as tooth age, tooth size, tooth shape, and the like, and oral cavity data such as saliva acidity-basicity, saliva viscosity, and the like, such data that can be directly judged by a local sensor, or some simple indexes such as brushing strength, which can directly determine the judgment degree through a numerical threshold, and can also be locally completed and directly display feedback to the user. In contrast, the data processing unit located at the cloud is more suitable for processing user data of a large number of users, performing dynamic tracking on the users, judging health conditions and feeding back information based on the dynamic tracking data, and executing a relatively comprehensive user portrait.

Fig. 2 is a schematic diagram of a non-hand-held intelligent dental scaler 200 that can be used as the intelligent oral care product of the present invention. Fig. 3 is a schematic view illustrating a construction of a pump socket part of the non-handheld intelligent dental scaler 200 of fig. 2. The dental scaler may include a hand-held scaler and a non-hand-held scaler, as well as a toothbrush type scaler and a bite type scaler according to its classification. It will be understood by those skilled in the art that the intelligent oral care product of the present invention is not limited to the non-handheld intelligent dental scaler described in fig. 2 and 3.

As shown in fig. 2 and 3, the dental scaler 200 may include a brush holder 201 and a brush head 202 having a shape corresponding to the teeth, and the brush holder 201 and the brush head 202 may be movably connected through a socket. The brush head 202 is provided with removable bristles 203 on its surface, and the brush head is provided with a slot 204 extending through both ends of the brush head, a sensor strip 205 is provided in the slot, and one or more pressure sensors 206 can be mounted on the sensor strip. A vibration generating circuit, a battery and a power management circuit can be installed in the brush seat 201, wherein the vibration generating circuit is electrically connected with a pressure sensor in the brush head through a socket, the battery supplies power for all parts in the non-handheld intelligent tooth cleaner, and the power management circuit charges the battery.

When the intelligent tooth cleaner 200 is used, a user can hold the brush head in the oral cavity and then bite the brush head with teeth, the pressure sensor senses the biting force of the user and then switches on the vibration generating circuit to enable the brush head to vibrate, and the bristles on the brush head clean the teeth in the vibration process. In the process, the vibration generation circuit adjusts the vibration strength of the brush head in real time according to the size of the occlusal force of the user, the occlusal force is large, the vibration strength is large, the occlusal force is small, the vibration strength is low, when the teeth of the user are loosened, the pressure sensor cannot sense the occlusal force of the user, and then the vibration generation circuit is disconnected to stop vibrating the brush head so that the user can take out the brush head from the oral cavity.

As one example, the brush head of the dental scaler 200 is customizable according to the user. The advantage of customization brush head lies in, on the one hand can more laminate user's oral cavity and tooth shape, realizes better clean tooth effect, and on the other hand still is favorable to more reasonable setting of sensor position to gather more accurate data. In addition, the design of the custom brush head can reduce the cost to the user, for example, multiple family members of a family can share a brush holder, which can also save the generally more limited bathroom counter space and power outlet requirements.

Fig. 4 shows a generalized structural schematic of a smart oral care product 102 that can be applied to the present invention. As shown in fig. 4, the smart oral care product 102 may include a data acquisition module 402, a data storage module 404, and a communication module 406. In addition, the smart oral care product 102 may also include functional units (not shown) for basic oral care functions, such as the brush holder, brush head, bristles, vibration generating circuits described in fig. 2 and 3, as well as battery and power management circuits to power the product, and the like.

The data acquisition module 402 may include various types of sensors including, but not limited to, a gyroscope/acceleration sensor, a pressure sensor, an image recognition sensor, an ultrasonic test sensor, a spectral test sensor, a ph sensor, a temperature sensor, and the like. These sensors are used to collect the various user oral health data and user health behavior data mentioned earlier, respectively. The same sensor can be used for acquiring different data or different purposes, for example, the image recognition sensor can be used for acquiring tooth images and can also be used for acquiring whole or other partial photos of the oral cavity of a user (for example, the photos are used for judging the gingival hyperemia condition, the oral mucosa ulcer condition, the tongue fur color, the lip rhagadia condition, the skin condition and the like), so that the use efficiency and the integration efficiency of the sensor of the intelligent oral care product are remarkably improved compared with the traditional intelligent tooth cleaner, and the types of the acquired data are greatly enriched. In yet another example, the image recognition sensor may also be used to capture images of the user's face, for user identification, or to capture other data that may directly or indirectly reflect the user's health, such as the user's eye congestion, skin condition, and the like. In addition, for other data which are not supposed at present, a corresponding sensor can be added.

The data storage module 404 may store programs, instructions, profiles, user information, etc. for controlling the various functions of the intelligent oral care product 102. The data storage module 404 may also be configured to temporarily store the collected data until the data is synchronized to an associated mobile computing device or uploaded directly to the data collection processing unit 104 in the cloud.

The communication module 406 may include various wired and wireless communication means and interfaces. For example, the communication module 406 may include a data interface for communicating with the mobile computing device 106 over a data line, which may include, but is not limited to: interfaces such as USB, Micro USB, USB Type-C, Lighting. The communication module 406 may also include a short-range wireless communication module, such as a bluetooth module, a Wi-Fi module, or the like, for wireless data communication with the mobile computing device 106. In addition, the communication module 406 may further include a 4G, 5G, or other cellular communication module for connecting to the internet to directly transmit data to the cloud-based data collection processing unit 104. Alternatively, the system can also be connected to an available Wi-Fi network via a Wi-Fi module, and then transmit the data to the data collection processing unit 104 in the cloud. The communication means and interfaces listed above are examples only and those skilled in the art will appreciate that any existing or future communication means may be integrated into the smart oral care product as part of the communication module for providing data communication of the smart oral care product with the outside.

Optionally, the smart oral care product 102 may also include a user identification module 408. User identification module 408 may be used to identify the identity of the user and associate it with the collected user data in order to ensure the correspondence, authenticity, and accuracy of the collected user data and the user identity. For example, when an intelligent oral care product 102 is bound to a user, if other users inadvertently use the product, the relevant data is not mistakenly bound to the user, resulting in the uploading of incorrect user health data. Furthermore, in instances where, for example, the brush head and base of a dental scaler may be separable, it is particularly desirable to differentiate the identity of the user to ensure that the correspondence of the brush head to the user is correct. In one embodiment, when user identification module 408 detects that an unidentified user picks up a product, a prompt may be issued to remind the user to use the correct product.

According to one embodiment of the invention, the data collection processing unit 104 may also use machine learning techniques to train and model the collected user data, and classify the user, make a health determination, predict the user's future health status, and the like based on the trained user model.

As previously mentioned, the data collection processing unit 104 may perform data analysis for a user to generate a user representation for the user. As one example, the user profile may encompass multi-dimensional user information including oral health data, facial health data, health behavior data collected by the intelligent oral care device 102, health data filled in and submitted by the mobile computing device 104, reporting data, and the like, while the data for each dimension may change over time, and the data collection processing unit 104 may present the latest data values for each dimension of data and historical dynamic changes of those data to the user through various data visualization techniques.

The collected user data may be used to train and build various oral health models, user health models, and the like as desired. As one example, fig. 5 shows a schematic flow diagram of a method that may be performed by the data collection processing unit to build a model (e.g., a model for determining caries/plaque conditions) using machine learning techniques based on collected user data (e.g., oral dental image data).

The method begins at step 502 with collecting collected user data. The user data may include the aforementioned oral health data, facial health data, health behavior data collected by the intelligent oral care device 102, and health data and reporting data populated and submitted by the mobile computing device 104, among others. At step 504, a training data set is generated. Training of the model requires a certain amount of training data. In this example, the training data may primarily include dental image data of the labeled user for caries/plaque condition determination. Caries/plaque condition markers can be classified into several grades ranging from none, mild, moderate, to severe. In the early stages, the dental image data may be labeled by a dentist or professional to construct labeled data. As more and more user data is collected over time, the data collection processing unit may automatically label the previous dental image data to form new training data when the user's historical dynamic data is able to reflect the user's true health changes. This process may be continuously iterative, and the training data set may thus be continuously supplemented and dynamically updated.

At step 506, the training data is trained into a trained model using machine learning. As an example, a determination model for determining the presence and degree of caries/dental plaque can be trained by training data of the labeled user dental image data. In one example, this model may be built based on static data. In particular, a training data set may be assembled from a single image and analyzed (e.g., to analyze the area, color, distribution, etc. of the shadows therein) in conjunction with other user data (user age, gender, tooth cleaning habits, etc.) associated with the point in time at which the image was acquired, with the aforementioned factors in the user data as input and caries/plaque presence and extent as output. Weights can be assigned to each input factor, and a set of weight coefficients can be obtained after model training is completed. Subsequently, when real-time user data is entered into the model, the model can give a prediction of caries/plaque condition.

In yet another example, such a model may be established based on dynamic data. More specifically, the model may be established based primarily on a set of oral dental image data of the same user at different times as training data. According to experimental data evaluation, the use of such a training model based on a group diagram showing the dynamic development of caries/dental plaque makes it possible to judge the caries/dental plaque condition more accurately than a training model based on a single static picture. In addition, the dynamic model may still further incorporate various other factors employed in the static model. Such dynamic models are particularly suitable for a health data collection system of the present invention that can conveniently collect daily data of a user. By inputting dynamic images of tooth images of a user in front and at a time into a model, the caries/dental plaque condition of the user can be judged more accurately. In addition, as the user data collected by the invention is increased, more and more data reflecting the real health change of the user are collected, and the dynamic data can be continuously changed into new training data, so that the dynamic model can be continuously trained and iterated, and the accuracy is further improved.

Similar examples also include modeling tooth deformities based on tooth position data at different times to discover potential users in need of orthodontic treatment. As yet another example, a model of the user's oral health may be established for the user's overall health of the teeth as a function of age. More specifically, caries, tooth loss, brushing habits of the same user's teeth at different ages may be collected, and the impact of many different factors on the user's oral health may be deduced, such as how likely a child will develop caries in the future, according to current oral hygiene practices, and how likely the user will lose teeth at 50, 55, 60 years, based on changes in tooth loosening that a user exhibits between 40 and 45 years, for example. When the model is established, real data of a plurality of different users at the same age can be used, and historical dynamic data of the same user can also be used, so that the user health data acquisition and processing system is extremely beneficial to the statistics of user health data and the analysis and training of the user health model.

FIG. 6 is an exemplary flow diagram of a method for building a user representation for a user based on collected user data, according to one embodiment of the invention. The method begins at step 602 by collecting user data. Collecting user data may include collecting oral health data, facial health data, health behavior data collected via the intelligent oral care device 102, and optionally health data and reporting data filled in and submitted via the user through, for example, the mobile computing device 104. Preferably, collecting user data comprises collecting dynamic user data over time.

At step 604, the collected data is input into one or more pre-trained models to obtain results of an assessment of one or more aspects of the user's health. The pre-trained models may be the various health models or user models described above in connection with FIG. 5, or may be other suitable models. The input data may be single user or multiple users, static data at a single point in time, or dynamic data at multiple points in time. The evaluation result can be aimed at specific aspects, such as caries condition, gum condition and the like, and can also be aimed at the overall health condition of the user, for example, the health condition of the user can be comprehensively evaluated based on a plurality of indexes including oral health condition and personal information of the user.

At step 606, a user representation is generated based on the collected user data and the evaluation results. The collected unprocessed data belongs to metadata, some of which can be directly presented to the user, such as visual data of oral bacteria content and approximate composition, salivary pH value, etc., and some of which are suitable for being processed and presented to the user in the form of evaluation results, such as caries/dental plaque condition which is more suitable for being presented to the user after being analyzed and evaluated compared with the original dental image data. Thus, user data and/or assessment results suitable for presentation can be combined to generate a user representation that is a multi-dimensional whole depicting the health of the user. The unrendered metadata will still be persisted for recall viewing when needed, and as part of the dynamic history data for training the model and result evaluation.

Optionally, at step 608, feedback information is presented to the user. The feedback information may comprise the user representation or at least a portion thereof. For example, in order to avoid excessive contents of feedback, only general information such as caries/plaque condition, number of teeth, overall oral health condition, overall physical health condition, and the like may be fed back to the user while health issues that need attention are fed back to the user while normal aspects are omitted. For example, if the user has a potential tooth loss problem (based on tooth looseness), the user has irregular tooth cleaning behavior, or has phenomena such as gum bleeding, abnormal oral bacteria content, etc., the user is presented with a reminder that the reminder is not needed if normal. In addition, the feedback information may also include recommendation information customized for the user. Based on the data analysis and the use of various models, other users or user groups with higher similarity to the user in one or more aspects can be found, and in this case, corresponding suggestions can be provided for the future body health change tracks of other users in the user group. For example, when a 40-year-old user and a 70-year-old user are found to be similar in various aspects of information at the age of 40, the experience between the ages of 40 and 70 of the 70-year-old user can be taken as a reference to recommend to the 40-year-old user, for example, "according to your current health condition and living habits, you may have teeth falling at the age of 50, and suggest that you start … … from now. As one example, the feedback information may be sent by the data collection processing unit to the mobile computing device for presentation to the user on a display device of the mobile computing device. Alternatively, the feedback information may be sent to the user or a third party via other means, such as by email, or to a medical facility designated by the user.

What has been described above includes examples of aspects of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the disclosed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.
