Description

[0002] Users with water intake restrictions, such as heart failure and gastrointestinal bleeding, often experience strong thirst due to the restriction of the intake amount. If the continuous thirst cannot be relieved in time, the user will suffer from strong discomfort, trigger anxiety, depression and other emotions, reduce the compliance of fluid restriction, and thus make the user intake excessive water -> increase blood volume -> increase the burden on the heart / kidney -> trigger complications (such as pulmonary edema and hypertensive crisis) -> further strengthen the treatment restriction demand, form a negative feedback cycle, and thus affect the prognosis. Therefore, it is necessary to accurately evaluate the thirst degree of the user with water intake restriction so as to timely perform individualized intervention.

[0003] The evaluation of the thirst degree is a process of judging the body fluid balance state by comprehensively considering symptoms, signs and objective examinations, and has the characteristics of stage, dynamics and individuality.

SUMMARY

[0004] The main purpose of the present application is to provide a multi-dimensional evaluation method and system for user thirst degree, which aims to solve the problem in the prior art that the evaluation is subjective and can only analyze and evaluate the approximate range of the thirst because the method mainly relies on the self-narration of the user, cannot match the real degree of water loss reflected by the body, especially when the user has early dehydration but no thirst, or the user exaggerates the thirst degree due to emotional and psychological factors.

[0056] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The occurrence of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0057] In order to enable those skilled in the art to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings.

[0058] The user thirst degree multi-dimensional evaluation method provided by the embodiments of the present application can be applied to a user thirst degree multi-dimensional evaluation application environment. The method can be applied to a terminal, a server, or a system including a terminal and a server, and is implemented through the interaction of the terminal and the server. The terminal can be, but is not limited to, various personal computers, notebook computers, etc. The terminal can evaluate the user's thirst degree in multiple dimensions by combining body fluid detection, blood detection, and appearance detection, etc. In the evaluation, the actual water deficiency degree of the user is accurately analyzed based on the body fluid detection and the blood detection through the water deficiency degree evaluation model designed by the present application, thereby avoiding the delay problem of the thirst degree. In addition, the actual thirst degree of the user is comprehensively analyzed based on the thirst degree range in the appearance detection image as a limiting standard and the actual water deficiency degree as a recognition basis, thereby avoiding the subjectivity, error, and limitation of human analysis, and improving the evaluation accuracy of the actual thirst degree of the user.

[0059] In one embodiment, as shown in Figure 1 The user thirst degree multi-dimensional evaluation method is described by taking the terminal as an example, which includes the following steps:

[0060] In step S101, the body fluid detection data of the user, the blood detection data of the user, and the appearance detection image of the user are acquired, and based on the appearance detection image of the user, each water deficiency characteristic feature of the user is extracted.

[0061] In this embodiment, the terminal acquires the body fluid detection data of the user and the blood detection data of the user by receiving the user detection data transmitted by the body fluid detection device and the blood detection device. The user is mainly a population of patients who need to limit water intake. The body fluid detection data includes but is not limited to body fluid discharge data and body fluid content data (i.e., the unit content value of each body fluid substance), and the blood detection data of the user includes blood content data (i.e., the unit content value of each blood substance). Then, the terminal obtains the appearance detection image of the user by image shooting of the appearance of the user and image collection of the eating and action of the user. The appearance detection image includes the lip image, the face image, and the oral cavity image of the user. Then, the terminal extracts each water deficiency characteristic feature of the user based on the appearance detection image of the user. The water deficiency characteristic features include but are not limited to the lip feature, the internal oral cavity skin feature, and the face skin feature, and the specific extraction method will be described in detail later.

[0062] In step S102, based on each water deficiency characteristic feature of the user, the thirst degree range of the user is identified, and based on the body fluid detection data of the user and the blood detection data of the user, the actual water deficiency degree of the user is identified by a water deficiency degree evaluation model.

[0063] In this embodiment, the terminal identifies the thirst degree range of the user based on each water deficiency characteristic feature of the user, and identifies the actual water deficiency degree of the user based on the body fluid detection data of the user and the blood detection data of the user by a water deficiency degree evaluation model. The water deficiency degree evaluation model is a classification evaluation model constructed by using a common machine learning classifier, such as a support vector machine (SVM), a logistic regression (LR), a random forest (RF), and a multi-layer perceptron (MLP). The specific identification process will be described in detail later.

[0064] In step S103, based on the thirst degree range of the user and the actual water deficiency degree of the user, the actual thirst degree of the user is identified.

[0065] In this embodiment, the terminal identifies the actual thirst level of the user based on the thirst level range of the user and the actual water deficiency level of the user. Specifically, the terminal presets a conversion program of the thirst level and the water deficiency level, and the conversion program is a proportion value table, wherein there is a fixed conversion proportion value between different thirst level ranges and water deficiency level ranges. The terminal calculates the thirst level value corresponding to the actual water deficiency level based on the conversion proportion value, and identifies the actual thirst level of the user based on the thirst level range of the user and the calculated thirst level value. The specific identification process will be described in detail later.

[0066] Based on the above scheme, the thirst level of the user is evaluated in multiple dimensions by combining body fluid detection, blood detection, and appearance detection. In this scheme, the actual water deficiency level of the user is accurately analyzed based on the body fluid detection and blood detection through the water deficiency level evaluation model designed in this scheme, thereby avoiding the delayed problem of the thirst level. In addition, the actual thirst level of the user is comprehensively analyzed based on the thirst level range in the appearance detection image as the limiting standard and the actual water deficiency level as the identification basis, thereby avoiding the subjective, error, and limited problems of human analysis, and thereby improving the evaluation accuracy of the actual thirst level of the user.

[0067] Optionally, based on the appearance detection image of the user, the user's water deficiency feature is extracted, including: filtering the range image of each water deficiency feature range in the appearance detection image of the user through a preset feature range filtering model; based on the range image of each water deficiency feature range, extracting the image feature data of each water deficiency feature range through an image feature extraction network, and identifying the user part type corresponding to each water deficiency feature range; and taking the image feature data corresponding to each user part type as the water deficiency feature of the user.

[0068] In this embodiment, the terminal filters the range image of each water deficiency feature range in the appearance detection image of the user through a preset feature range filtering model. The feature range filtering model is a convolutional neural network based on deep learning, which extracts the image of the water deficiency feature range concerned in each appearance detection image to obtain the range image of each water deficiency feature range. The water deficiency feature range includes but is not limited to the mouth range, the oral cavity range, the face range, etc.

[0069] Then, the terminal extracts image feature data of each water shortage representation range through an image feature extraction network based on the range image of each water shortage representation range, and identifies the user part type corresponding to each water shortage representation range. The terminal predefines the correspondence between different water shortage representation ranges and user part types of the user, for example, the mouth range corresponds to the mouth part type of the user, the oral cavity range corresponds to the oral cavity part type of the user, and the face range corresponds to the face part type of the user. The image feature extraction network is a convolutional neural network based on an attention mechanism.

[0070] Finally, the terminal takes the image feature data corresponding to each user part type as the water shortage representation features of the user.

[0071] Based on the above scheme, the image features of specific user parts are extracted to identify water shortage representation features, thereby improving the comprehensiveness and accuracy of water shortage representation identification.

[0072] Optionally, based on the water shortage representation features of the user, the thirst degree range of the user is identified, including: for each user part type, based on the image feature data of the user part type, the sub-thirst degree range corresponding to the user part type is identified through the thirst degree evaluation strategy corresponding to the user part type; based on the sub-thirst degree range corresponding to each user part type, the thirst degree range of the user is identified through the pre-set thirst representation weight value of each user part type.

[0073] In this embodiment, the terminal identifies the sub-thirst degree range corresponding to each user part type based on the image feature data of the user part type through the thirst degree evaluation strategy corresponding to the user part type for each user part type. Each user part type corresponds to a different thirst degree evaluation strategy. Each thirst degree evaluation strategy includes a correspondence between each image feature data range and a thirst degree value, and the terminal identifies the sub-thirst degree value corresponding to each user part type through the correspondence.

[0074] Then, the terminal performs summing processing on the sub-thirst degree values corresponding to each user part type through the pre-set thirst representation weight value of each user part type to obtain the initial thirst degree value of the user. Since there is a time delay between the physical representation and the actual thirst degree, the terminal performs range screening on the initial thirst degree value based on the pre-set degree range width value, that is, screens the thirst degree range with the initial thirst degree value as the center and the degree range width value as the range width, as the thirst degree range of the user.

[0075] Based on the above scheme, the sub-thirst degree values identified by combining different user part types are combined, and then weighted summation is performed to obtain the initial thirst degree value of the user, so that different user performance characteristics and the correlation weight of different part sign representations with the actual thirst degree of the user are considered, thereby intelligently identifying the thirst degree range of the user and improving the identification accuracy of the thirst degree range of the user.

[0076] Optionally, based on the body fluid detection data and the blood detection data of the user, the actual water deficiency degree of the user is identified through a water deficiency degree evaluation model, including: based on the body fluid detection data of the user, the body fluid excretion data and the body fluid content data of the user are identified, and based on the body fluid excretion data of the user, the excretion abnormal information of the user is identified; based on the blood detection data of the user, the blood content data of the user is identified, and based on the body fluid content data, the blood content data, and the excretion abnormal information of the user, the actual water deficiency degree of the user is identified through the water deficiency degree evaluation model.

[0077] In this embodiment, the terminal identifies the body fluid excretion data and the body fluid content data of the user based on the body fluid detection data of the user, and identifies the excretion abnormal information of the user based on the body fluid excretion data of the user. The excretion abnormal information includes but is not limited to the number of excretions per unit time (such as half a day, 1 day, 3 hours, 2 hours, 1 hour, etc.) being lower than a preset number threshold, or the single excretion amount being lower than a preset excretion amount threshold.

[0078] Then, the terminal identifies the blood content data of the user based on the blood detection data of the user, and identifies the actual water deficiency degree of the user based on the body fluid content data, the blood content data, and the excretion abnormal information of the user through the water deficiency degree evaluation model. The specific identification process will be described in detail later.

[0079] Based on the above scheme, the actual water deficiency degree of the user is detected by combining the detection data of the body fluid and the blood, thereby improving the identification accuracy of the actual water deficiency degree of the user.

[0080] Optionally, based on the user's body fluid content data, the user's blood content data, and the user's excretion abnormal information, the actual water deficiency degree of the user is identified through a water deficiency degree evaluation model, including: based on the user's excretion abnormal information, the excretion frequency of the user and the excretion amount distribution information of the user are identified, and based on the excretion frequency of the user and the excretion amount distribution information of the user, the water deficiency degree range of the user is identified through a water deficiency evaluation strategy; based on the user's body fluid content data and the user's blood content data, the target substance proportion information of the user's body fluid and the target substance proportion information of the user's blood are calculated; based on the target substance proportion information of the body fluid and the target substance proportion information of the blood, the actual water deficiency degree of the user is adapted in the water deficiency degree range through the water deficiency degree evaluation model.

[0081] In this embodiment, the terminal identifies the excretion frequency of the user and the excretion amount distribution information of the user based on the user's excretion abnormal information, and identifies the water deficiency degree range of the user based on the excretion frequency of the user and the excretion amount distribution information of the user through a water deficiency evaluation strategy. Among them, the water deficiency evaluation strategy includes the corresponding relationship between different excretion frequency ranges, excretion amount distribution trend ranges, and water deficiency degree ranges, and the terminal identifies the initial water deficiency degree range corresponding to the user based on the corresponding relationship. Then, the terminal adapts the water deficiency degree range corresponding to the initial water deficiency degree range in the body state database based on the user's age, gender, body shape, and diet state information, etc., to obtain the water deficiency degree range of the user. Among them, the body state database includes the corresponding relationship between different age ranges, gender, body shape ranges, and diet state ranges, and water deficiency degree deviation values, and the terminal identifies the water deficiency degree deviation value corresponding to the user through the corresponding relationship, and adjusts the range of the initial water deficiency degree range according to the water deficiency degree deviation value to obtain the water deficiency degree range.

[0082] Then, the terminal calculates the target substance proportion information of the user's body fluid and the target substance proportion information of the user's blood based on the user's body fluid content data and the user's blood content data. Among them, the target substance proportion information of the body fluid is the content proportion value of substances such as urea, uric acid, and inorganic salt. And the target substance proportion information of the blood is the electrolyte ion content proportion information, for example, sodium, potassium, chlorine, calcium, magnesium, etc.

[0083] Finally, the terminal adapts the actual water deficiency degree of the user in the water deficiency degree range based on the body fluid target substance proportion information and the blood target substance proportion information through a water deficiency degree evaluation model. The water deficiency degree evaluation model can generate a water deficiency degree value corresponding to the body fluid target substance proportion information and the blood target substance proportion information. However, the water deficiency degree value may change due to the influence of the body specificity of the user and the body state of different age stages of the user. Therefore, the water deficiency degree value and the water deficiency degree range of the user need to be adapted. When the water deficiency degree value exceeds the water deficiency degree range, the boundary value of the water deficiency degree range closest to the water deficiency degree value is used as the actual water deficiency degree. When the water deficiency degree value does not exceed the water deficiency degree range, the water deficiency degree value is directly used as the actual water deficiency degree.

[0084] Based on the above scheme, the actual water deficiency degree of the user is comprehensively analyzed by combining the excretion information and the substance proportions in the body fluid and the blood. The water deficiency degree range is adaptively adjusted based on the basic information of the body of the user and the diet information, so as to ensure that the actual water deficiency degree obtained conforms to the actual water deficiency degree of the user at present, and the accuracy of obtaining the actual water deficiency degree is improved.

[0085] Optionally, the actual thirst degree of the user is identified based on the thirst degree range of the user and the actual water deficiency degree of the user, including: identifying a thirst degree evaluation value of the user through a thirst degree conversion strategy based on the actual water deficiency degree of the user; and identifying the actual thirst degree of the user based on the thirst degree range of the user and the thirst degree evaluation value of the user.

[0086] In this embodiment, the terminal identifies a thirst degree evaluation value of the user through a thirst degree conversion strategy based on the actual water deficiency degree of the user. Specifically, the terminal first identifies the water deficiency degree range to which the actual water deficiency degree belongs, and then identifies a conversion proportion value corresponding to the water deficiency degree range based on the thirst degree conversion strategy. Then, the terminal multiplies the actual water deficiency degree by the conversion proportion value to obtain the thirst degree evaluation value of the user.

[0087] Finally, the terminal identifies the actual thirst degree of the user based on the thirst degree range of the user and the thirst degree evaluation value of the user. Specifically, since the actual thirst degree of the user has a delay, the evaluation of the thirst degree of the user needs to be judged based on the thirst degree range to obtain the accurate thirst evaluation value of the user at present. Therefore, when the thirst degree evaluation value exceeds the thirst degree range, the terminal uses the boundary value of the thirst degree range closest to the thirst degree evaluation value as the actual thirst degree. When the thirst degree evaluation value does not exceed the thirst degree range, the terminal directly uses the thirst degree evaluation value as the actual thirst degree.

[0088] Based on the above scheme, by taking the thirst degree range in the appearance detection image as the limited standard, and taking the actual water deficiency degree as the identification basis, the actual thirst degree of the user is comprehensively analyzed, the problems of subjectivity, error and limitation of human analysis are avoided, and the evaluation accuracy of the actual thirst degree of the user is comprehensively improved.
