Referring to fig. 1, in an embodiment of the present invention, a noninvasive intelligent blood glucose measuring instrument 100 includes: the device comprises a processor 1, an input and output device 2, a finger near-infrared image acquisition device 3 and an external device 4. The finger near-infrared image capturing device 3 captures near-infrared images of the fingers of the user (images captured by the near-infrared camera under near-infrared light), and then the images are transmitted to the processor 1 for processing, and after comparison and calibration are completed in the processor 1, the result is output. The result can be displayed in the input and output device 2 integrated into the noninvasive intelligent blood glucose measuring instrument 100 and also can be transmitted to the external device 4. It should be understood that, although the present invention is described by using the finger near-infrared image capturing module in the illustrated embodiment, the present invention is not limited thereto, and various human body near-infrared image capturing modules, for example, a palm near-infrared image capturing module, etc., may be applied.

It should be understood that in other embodiments of the present invention, the input/output device 2 and the external device 4 may not be included. They are illustrated together in this embodiment for the purpose of exhaustive description, but this does not imply that these components are essential.

As shown in fig. 1, the finger near-infrared picture taking device 3 includes a near-infrared camera 31, a near-infrared light source part 32, and a finger fixing device 33. The near-infrared camera 31 is used to take a near-infrared picture of a finger, and the near-infrared light source section 32 is used to emit near-infrared light to the finger of the user so that the near-infrared camera 31 takes a picture. When the user correctly places the finger on the finger fixing device 33, the near-infrared light source part 32 sequentially emits four kinds of near-infrared light of different wavelengths, and the near-infrared camera 31 sequentially takes four near-infrared pictures of different wavelengths. It should be understood that while near infrared light is preferred in this embodiment, other embodiments are possible in which other bands of light are employed, and such alternatives should not be excluded from the scope of the present invention. It should also be understood that while the present embodiment is preferred to capture photographs of four different wavelengths of near infrared light, in other embodiments it is possible to use one, two, or three, five, or even more different wavelengths of photographs, and such alternatives should not be excluded from the scope of the present invention.

Referring to fig. 1, the near-infrared light source part 32 is located above the finger hold 33, and the near-infrared camera 31 is located below the finger hold 33. A layer of transparent glass is arranged between the finger fixing device 33 and the near infrared camera 31. The transparent glass plays a dustproof role in the near-infrared camera 31; the near infrared camera 31 can photograph a finger through the glass. It is emphasized again that "up" and "down" in this embodiment merely indicate relative positions between the components, and in other embodiments, for example, the near-infrared light source component 32 may be located on the left side of the finger holder 33, and the near-infrared camera 31 may be located on the right side of the finger holder 33. Of course, the position of the one side and the other side is preferably the position of the opposite side, but may be a certain range of positions deviating from the position of the opposite side in some embodiments. It should be understood by those skilled in the art that these solutions should not be excluded from the scope of the present invention as long as the near-infrared light source component 32 can illuminate the finger of the user and the near-infrared camera 31 can take the picture of the near-infrared light passing through the finger. It should be understood that if a near-infrared image capture module of another human body part is used, such as a palm near-infrared image capture module, the finger holder of the illustrated embodiment may be designed as a holder for another human body part, such as a palm holder.

The finger hold means 33 is a "U-shaped" recess with a hollow bottom. The top end (corresponding to the finger tip) of the U-shaped structure is provided with a capacitive touch sensing switch, and the touch sensing function of the capacitive touch sensing switch is triggered by a capacitive sensing chip circuit arranged at the top end. It should be understood that in other embodiments, the finger holds 33 may be other than U-shaped and may have other suitable shapes; the bottom of the device is not necessarily hollow, so long as the near-infrared camera 31 can shoot a picture of near-infrared light passing through fingers; the inductive touch switch is not necessarily arranged at the top end of the U shape, and other suitable positions are also possible. It should also be understood that although the sensing touch switch is capacitive in this embodiment, other forms of sensing touch switches are possible; also, even other forms of switches, such as mechanical switches, light sensitive switches or voice activated switches are possible. None of these alternatives should be excluded from the scope of the present invention.

When the top end of the finger touches the switch at the top end, the process of shooting the near-infrared picture is started. The near-infrared light source unit 32 includes four sets of near-infrared lamps, each set including one or more near-infrared lamps, and preferably 2 to 6 near-infrared lamps. Each group of near-infrared lamps can emit near-infrared light with the group of wavelengths when being started. When the near-infrared camera 31 starts the shooting process, the groups of wavelength near-infrared lamps are sequentially turned on, and finger near-infrared pictures at the wavelength are shot accordingly. Specifically, the near-infrared light source unit 32 turns on the near-infrared light of the first wavelength, the near-infrared camera 31 takes a photograph of the finger near-infrared light of the first wavelength, then the near-infrared light source unit 32 turns off the near-infrared light of the first wavelength, turns on the near-infrared light of the second wavelength, the near-infrared camera 31 takes a photograph of the finger near-infrared light of the second wavelength, then the near-infrared light source unit 32 turns off the near-infrared light of the second wavelength, turns on the near-infrared light of the third wavelength, the near-infrared camera 31 takes a photograph of the finger near-infrared light of the third wavelength, then the near-infrared light source unit 32 turns off the near-infrared light of the third wavelength, turns on the near-infrared light of the fourth wavelength, and the near-infrared camera 31 takes a photograph of the finger near-infrared light of the fourth wavelength. In a preferred embodiment, the entire photographing process takes less than 1 second. After the photographing is finished, the user can remove the finger from the finger fixing device 33 by himself. It should be understood that in some embodiments, the above-described lighting and photographing processes may be automatically performed upon activation, and in other embodiments, the processes may be controlled by a user, for example, through the above-described switch or another switch. It should also be understood that in some embodiments, after the photographing is finished, the user may be prompted in a light or sound manner, for example, the prompt may be sent on the input/output device 2 or the external device 4 of the noninvasive intelligent blood glucose measuring instrument 100; of course, a warning light or a horn may be provided for warning. None of these alternatives should be excluded from the scope of the present invention.

The four different wavelengths of the near-infrared light source component 32 are all between 700 nm and 1800 nm. In a preferred embodiment, the first wavelength is set between 700-800nm, the second wavelength is set between 800-900nm, the third wavelength is set between 900-1000nm, and the fourth wavelength is set between 1000-1100 nm. In a more preferred embodiment, the first wavelength is set between 740-800nm, the second wavelength is set between 840-900nm, the third wavelength is set between 940-1000nm, and the fourth wavelength is set between 1040-1100 nm.

As shown in fig. 1, the processor 1 is preferably a CPU processor, which includes a picture processing module, an alignment calibration module and a data management module (not shown). The image processing module processes the near-infrared image collected by the finger near-infrared image collecting device 3 and then transmits the processed near-infrared image to the comparison and calibration module for comparison and calibration, and the result of the comparison and calibration module is output to the data management module, and the data is analyzed and then output to the input and output device 2 or the external device 4 for a user.

In the picture processing module, the collected near-infrared picture is associated with the near-infrared wavelength during shooting, and the picture is compared and calibrated based on specific wavelength information in the comparison and calibration module. In a preferred embodiment, the comparison and calibration module reflects the corresponding blood glucose index through four near-infrared pictures with different wavelengths, and obtains the final blood glucose index through comparison and calibration. In some embodiments, a program for controlling the finger near-infrared image capturing device 3 to take a picture may be integrated into the image processing module. Of course, the functions of the image processing module may also be integrated into the comparison calibration module, or directly integrated into the finger near-infrared image capturing device 3.

In a preferred embodiment, the comparison calibration module is obtained by training an artificial intelligence machine learning algorithm, such as a deep learning algorithm, and the blood glucose value of the corresponding user can be obtained by sending the processed near-infrared image to the comparison calibration module. Specifically, the comparison calibration module is obtained by using a large amount of specially collected original data, accurately sorting and matching the data to serve as basic training data, and then applying a deep learning algorithm to a computer with high computing power, such as a GPU computer for training. The original data comprises a finger near-infrared light image of the person to be collected and a corresponding blood sugar index. The wavelength of the near-infrared light corresponding to the finger near-infrared light image used by the training data is the same as the wavelength of the near-infrared light used in the finger near-infrared image acquisition device 3. For example, the finger near-infrared pictures in the training data are also collected by four different wavelengths between 700 nm and 1800 nm. Preferably, four different wavelengths between 700-800nm, 800-900nm, 900-1000nm and 1000-1100nm are used for the collection. More preferably, four different wavelengths between 740-800nm, 840-900nm, 940-1000nm and 1040-1100nm are used for the acquisition.

In a preferred embodiment, the corresponding glycemic index values of the acquired training data are distributed between 3.6-22.0 over a span of 0.1, and at least 40 pictures are acquired at each wavelength for each blood glucose value. Of course, it should be understood that other numerical range distributions and spans, as well as the number of captured photographs, may be adjusted. None of these alternatives should be excluded from the scope of the present invention.

In a preferred embodiment, the trained model (engine) is embedded in the comparison calibration module, and the blood glucose level of the user can be directly calculated after the near-infrared picture of the user is input. Therefore, the user does not need to draw blood to detect the blood sugar by using a traditional method, and does not need to draw blood by using the traditional method to establish a corresponding model of the blood sugar index value of the user in the initial stage like other non-pure 'non-invasive' blood sugar meters. Meanwhile, the trained model also ensures that the glucometer of the utility model can work under the condition without a network, namely all the measurement, calculation and storage work can be completed locally on the glucometer without intervention of a cloud (such as cloud storage, cloud calculation and the like); of course, the utility model discloses a blood glucose meter does not exclude the cooperation with high in the clouds device.

The data management module is used for managing the relevant information of the user and carrying out relevant analysis on the historical data of the blood sugar value measured by the user. In the data management module, a user information registration sub-module may be included for registering basic information of the user, including the user's name, age, sex, home address, and other additional specifications. Preferably, a plurality of users can be registered by the user information registration submodule. The data management module may further include a historical data analysis submodule by which a historical database of blood glucose level measurements can be created for each user, and the blood glucose level measurements can be output to the input/output device 2 and/or the external device 4 in the form of an appropriate graph and fed back to the user. At the same time, the current measurement data and the change of the historical data of the user can also give out specific health care suggestions, and the suggestions can also be output to the input and output device 2 and/or the external device 4 and fed back to the user.

It should be appreciated that in other embodiments of the present invention, some or all of the data management module may not be included. They are illustrated together in the present embodiment for the purpose of exhaustive description, but this does not mean that these modules are necessary.

As shown in fig. 1, the input/output device 2 is a touch screen, and is mounted on the main body of the noninvasive intelligent blood glucose measuring instrument 100 together with the processor 1 and the finger near-infrared image capturing device 3. The input and output device 2 is used for inputting, editing and presenting personal information of each user and the condition of measuring blood sugar, historical data, analysis results and nursing suggestions thereof. When there is a measurement result, the input-output device 2 may output the result directly according to the user's setting, or output in combination with the history data and/or the care advice. If there is no measurement result, the input-output device 2 may give a prompt to let the user measure again. It should be understood that the input/output device 2 may be, for example, a capacitive or resistive touch screen, and in other embodiments, may be a conventional form of non-touch screen plus physical buttons, or an input/output form using voice. None of these alternatives should be excluded from the scope of the present invention.

The external device 4 can be a user's own mobile phone, Pad computer or PC computer. In a preferred embodiment, it communicates with the processor 1 in a wired or wireless manner, and a corresponding interface or communication module is provided on the noninvasive intelligent blood glucose meter 100 to communicate with it; if necessary, a corresponding APP program or API program is also used. The wireless mode includes, for example, WiFi, bluetooth, Zigbee, etc., and also includes, for example, 3G, 4G, 5G, etc. Of course, the external device 4 may also be a component that is manufactured and sold together with other components of the non-invasive intelligent blood glucose meter 100, but is separate from the main body of the non-invasive intelligent blood glucose meter 100. It should be understood by those skilled in the art that if the aforementioned input/output device 2 is also disposed outside the main body of the noninvasive intelligent blood glucose meter 100, the input/output device 2 can be regarded as an external device in a sense. It will also be understood by those skilled in the art that the input-output device 2 and the external device 4 are not mutually exclusive and may be used simultaneously. Such alternatives should not be excluded from the scope of the present invention.

If the blood sugar value of the user cannot be obtained after the processing of the CPU processor 1, the user is requested to put the finger again for collection and analysis. After obtaining the blood sugar value of the user, the user can also select a time period to inquire the historical data of the blood sugar value in the time period and the analysis result thereof.

It should be understood that, although the present invention is explained by taking and analyzing the near infrared image of the finger in the above embodiments, the present invention is not limited to the embodiment only based on the finger of the user. Other suitable ways, such as taking a picture of collecting and analyzing the palm or other limb segment of the human body, are also possible. These alternatives should not be excluded from the scope of the present invention.

In addition, it should be understood by those skilled in the art that due to the variety of combinations of hardware and software (including firmware), a single software function is not necessarily implemented by only one piece of hardware, and various software functions may be implemented by being integrated into one piece of hardware or distributed among multiple pieces of hardware. The separation or integration of hardware, as well as not specifically illustrated, does not limit the functionality of the software. In particular, due to advances in cloud storage and cloud computing technologies, some functions may be implemented either locally, on the "cloud," or both. None of these alternatives should be excluded from the scope of the present invention unless otherwise specifically stated.
