Description

Technical Field

[0001] The present invention relates to a blood sugar detection device, in particular to a non-invasive blood sugar detection device with a wearing fit detection function. Background Art

[0002] Most existing non-invasive blood glucose detection devices are designed to be worn by users on specific parts of the body, such as upper or lower limbs, and the detection unit is attached to the skin surface of the specific part and performs the sending and receiving of optical signals to detect the blood glucose value in the user's blood. Since the existing non-invasive blood glucose detection devices must be fixed to the specific part of the user's body with the assistance of accessories such as bracelets, fixing belts, adhesives, etc., once the user wears it incorrectly or the position is deviated, the existing non-invasive blood glucose detection device will not fit tightly with the skin and a large gap will be generated, which will easily cause the optical signal to be lost during the sending or receiving process, thereby affecting the accuracy of the detection.

[0003] Therefore, how to design a non-invasive blood glucose detection device that can improve the above-mentioned problems is indeed a topic worth studying. Summary of the invention

[0004] The object of the present invention is to provide a non-invasive blood glucose detection device with a wearing fit detection function.

The substrate defines a first setting area and a second setting area, and the second setting area is between the edge of the substrate and the first setting area. The blood glucose detection module is disposed in the first setting area, and the optical feedback detection module is disposed in the second setting area. The optical feedback detection module includes at least one light-emitting element and at least one photosensitive element. Each light-emitting element emits a light signal corresponding to at least one specific wavelength, and each photosensitive element receives a light signal corresponding to at least one specific wavelength after reflection as a basis for judging the wearing fit. At least one light blocking wall is located between the first setting area and the second setting area to block the blood glucose detection module and the optical feedback detection module.

[0007] In one embodiment of the present invention, the photosensitive element corresponds to a wavelength response range, and a plurality of specific wavelengths are included in the wavelength response range.

[0008] In one embodiment of the present invention, the wavelength response range is between 500 nm and 1100 nm.

[0009] In one embodiment of the present invention, the center distance between each light emitting element and the adjacent light sensing element is between 1 mm and 4 mm.

[0010] In an embodiment of the present invention, the number of the at least one light emitting element is not less than the number of the at least one photosensitive element.

[0011] In one embodiment of the present invention, when there are multiple at least one light emitting element and multiple at least one photosensitive element, the light emitting elements and the photosensitive elements are symmetrically arranged based on the blood sugar detection module.

[0012] In one embodiment of the present invention, the non-invasive blood glucose monitoring device with a wearing fit detection function further includes a processing unit, which uses a photoplethysmography method to analyze the reflected light signal corresponding to at least one specific wavelength to determine the wearing fit of the device.

[0013] In one embodiment of the present invention, the first disposition area is located at the center of the substrate, and the second disposition area surrounds the first disposition area.

[0014] In one embodiment of the present invention, the optical feedback detection module further includes at least one blocking structure, each blocking structure is disposed between any light emitting element and an adjacent light sensing element, and each blocking structure extends from an edge of the substrate to connect to or be adjacent to any light blocking wall.

[0015] In one embodiment of the present invention, the non-invasive blood glucose detection device with a wearing fit detection function further includes a packaging structure disposed on the substrate, and the packaging structure is used to package the blood glucose detection module and the optical feedback detection module.

[0016] In one embodiment of the present invention, the non-invasive blood glucose detection device with a wearing fit detection function further includes a transparent cover plate disposed on the packaging structure to protect the blood glucose detection module and the optical feedback detection module.

[0017] Accordingly, the present invention uses the optical feedback detection module and the photoplethysmography method to analyze the light signal to determine whether the user has correctly worn the non-invasive blood glucose detection device, which can better ensure the reliability and accuracy of blood glucose detection compared to the existing non-invasive blood glucose detection module. And by setting at least one light blocking wall, the signal detection mutual interference between the blood glucose detection module and the optical feedback detection module can be avoided.

[0054] Since the various schemes and embodiments are only illustrative and non-limiting, after reading this specification, people with ordinary technical knowledge may also come up with other schemes and embodiments without departing from the scope of the present invention. According to the following detailed description and claims, the features and advantages of these embodiments will be more prominent.

[0055] In this document, "a" or "an" is used to describe the elements and components described herein. This is only for convenience of description and to provide a general meaning to the scope of the present invention. Therefore, unless it is obvious that it is otherwise intended, such description should be understood to include one or at least one, and the singular also includes the plural.

[0056] In this document, the terms "first" or "second" and the like are mainly used to distinguish or refer to the same or similar elements or structures, and do not necessarily imply the order of these elements or structures in space or time. It should be understood that in some cases or configurations, the ordinal numbers can be used interchangeably without affecting the implementation of the present invention.

[0057] As used herein, the terms "include", "have" or any other similar terms are intended to cover a non-exclusive inclusion. For example, an element or structure containing multiple elements is not limited to only those elements listed herein, but may include other elements that are not explicitly listed but are generally inherent to the element or structure.

[0058] Please refer to Figures 1 to 2C ,in Figure 1 is a schematic diagram of a non-invasive blood glucose detection device with a wearing fit detection function according to the present invention, Figure 2A is a top view of a first embodiment of a non-invasive blood glucose detection device with a wearing fit detection function according to the present invention, Figure 2B For along Figure 2A A cross-sectional view of the midline segment A, and Figure 2C For along Figure 2A The cross-sectional view of the midline segment B. Figure 1 and Figure 2A As shown, the non-invasive blood glucose detection device 1 with a wearing fit detection function of the present invention includes a substrate 10, a blood glucose detection module 20, an optical feedback detection module 30 and at least one light blocking wall 40, and the blood glucose detection module 20, the optical feedback detection module 30 and at least one light blocking wall 40 are all arranged on the substrate 10. A conductive circuit is pre-arranged on the substrate 10 to form an electrical connection with the blood glucose detection module 20 and the optical feedback detection module 30. In the present invention, the substrate 10 can be a ceramic substrate, a silicon substrate or a PCB substrate, but the present invention is not limited thereto, and the substrate 10 can also be made of other materials. The overall structural appearance of the substrate 10 can be changed according to different design requirements, for example, the substrate 10 can be rectangular or circular.

[0059] In the present invention, the substrate 10 defines a first setting area 11 and a second setting area 12, and the second setting area 12 is between the edge 13 of the substrate 10 and the first setting area 11. The first setting area 11 is used to set the blood glucose detection module 20, and the second setting area 12 is used to set the optical feedback detection module 30. As the position of the first setting area 11 changes, the position of the second setting area 12 will also change relatively. For example, in this embodiment, if the first setting area 11 is located at the central position of the substrate 10, the second setting area 12 is arranged around the first setting area 11, so that the second setting area 12 forms a frame-like area located outside the first setting area 11, but the positions of the first setting area 11 and the second setting area 12 are not limited to this.

[0060] The blood sugar detection module 20 is disposed in the first setting area 11 of the substrate 10, and the blood sugar status of the user is detected by the blood sugar detection module 20. The blood sugar detection module 20 includes at least one light source 21, at least one photo sensor (Photo Detector) 22 and at least one barrier 23. Each light source 21 mainly emits light of a fixed wavelength to the user's skin. Each light source 21 can be a single LED, but the type of the light source 21 is not limited to this. Each light source 21 can be electrically connected to the substrate 10 through a welding wire. Each photo sensor 22 mainly receives the light of a fixed wavelength transmitted back after diffuse reflection from the skin. Each photo sensor 22 can be electrically connected to the substrate 10 through a welding wire. Each barrier 23 is used to separate at least one light source 21 and at least one adjacent photo sensor 22. Each barrier 23 can be made of black plastic or other materials with non-light-transmitting (including visible light and invisible light) properties. The number and position of at least one light source 21, at least one light sensor 22 and at least one barrier 23 may vary depending on design requirements. For example, in the present embodiment, the blood glucose detection module 20 forms a 4x5 matrix by 16 light sources 21 and 4 light sensors 22, and the light sensors 22 are separated from the light sources 21 by two barriers 23 located on both sides to perform the blood glucose detection function, but the present invention is not limited thereto.

[0061] The optical feedback detection module 30 is disposed in the second setting area 12 of the substrate 10, and the optical feedback detection module 30 is used to detect the wearing fit of the user when wearing the device. The optical feedback detection module 30 includes at least one light emitting element 31 and at least one photosensitive element 32. Each light emitting element 31 emits a light signal corresponding to at least one specific wavelength. In the present invention, each light emitting element 31 adopts a multi-chip LED light source, and the multiple LED chips contained therein correspond to the emission of multiple specific wavelengths of light signals, but each light emitting element 31 can also adopt a single LED light source to correspond to the emission of a single specific wavelength of light signals according to different design requirements. The type, setting position and number of at least one light emitting element 31 can be adjusted according to different design requirements. In one embodiment of the present invention, each of the above-mentioned specific wavelengths is between 500nm and 1100nm. It should be noted that any specific wavelength corresponding to the light signal emitted by each light emitting element 31 of the optical feedback detection module 30 is different from the fixed wavelength corresponding to the light signal emitted by each light source 21 of the blood glucose detection module 20, so as to avoid mutual interference between the blood glucose detection function and the wearing fit detection function. The light emitting element 31 may be electrically connected to the substrate 10 via bonding wires.

[0062] Each photosensitive element 32 receives a light signal corresponding to at least one specific wavelength after being reflected by the skin as a basis for judging the degree of fit. In the present invention, each photosensitive element 32 can adopt a single photodetector, and the photosensitive element 32 can be designed to correspond to a wavelength response range, and at least one specific wavelength corresponding to the light signal emitted by the aforementioned light-emitting element 31 is included in the wavelength response range, so that the photosensitive element 32 can sense the light signal with a specific wavelength. The type, setting position and number of at least one photosensitive element 32 can be adjusted according to different design requirements. The photosensitive element 32 can be electrically connected to the substrate 10 through a welding wire.

[0063] In one embodiment of the present invention, it is assumed that each light-emitting element 31 is a multi-chip LED light source having 4 LED chips, and the multiple specific wavelengths corresponding to the light signal emitted by the light-emitting element 31 are 530nm, 660nm, 850nm and 940nm respectively; accordingly, a wavelength response range corresponding to the wavelength between 500nm and 1100nm can be designed for each photosensitive element 32, so that the multiple specific wavelengths corresponding to the light signal emitted by the light-emitting element 31 are covered within the wavelength response range of the photosensitive element 32.

[0064] In one embodiment of the present invention, the number of at least one light-emitting element 31 is not less than the number of at least one photosensitive element 32. That is, in design, each photosensitive element 32 will detect the light signal emitted by one or more light-emitting elements 31. For example, the optical feedback detection module 30 basically uses one photosensitive element 32 and one light-emitting element 31 as each independent detection unit to perform the wearing fit detection of the device, but according to different design requirements, the optical feedback detection module 30 can also use one photosensitive element 32 and two light-emitting elements 31 as each independent detection unit. When one photosensitive element 32 is used with two light-emitting elements 31, the two light-emitting elements 31 are respectively located on different sides of the photosensitive element 32, and the center distance between each light-emitting element 31 and the photosensitive element 32 is the same. In order to facilitate the transmission and reception of light signals to maintain the detection accuracy, in one embodiment of the present invention, the center distance between each light-emitting element 31 and the adjacent photosensitive element 32 is between 1 mm and 4 mm, but the present invention is not limited thereto.

[0065] In one embodiment of the present invention, when there are at least one light emitting element 31 and at least one photosensitive element 32, the light emitting elements 31 and the photosensitive elements 32 are symmetrically arranged based on the blood glucose detection module 20. For example, in this embodiment, the substrate 10 is a square structure, the first setting area 11 is located at the center of the substrate 10 for setting the blood glucose detection module 20, and the second setting area 12 forms a rectangular frame area located outside the first setting area 11 for setting the optical feedback detection module 30. The optical feedback detection module 30 has 4 photosensitive elements 32 and 4 light emitting elements 31, the 4 photosensitive elements 32 are respectively located at the 4 corners of the rectangular frame area formed by the second setting area 12, and the 4 light emitting elements 31 are respectively located at the middle position of two adjacent photosensitive elements 32 based on the blood glucose detection module 20, so that the light emitting elements 31 and the photosensitive elements 32 are symmetrically arranged based on the blood glucose detection module 20.

[0066] At least one light-blocking wall 40 is located between the first setting area 11 and the second setting area 12 of the substrate 10 to block the blood glucose detection module 20 and the optical feedback detection module 30. In the present invention, at least one light-blocking wall 40 can be a plurality of light-blocking walls 40 that are discontinuous in structure and arranged in sections, and each light-blocking wall 40 can be located between any one of the light source 21 and the light sensor 22 of the blood glucose detection module 20 and any one of the light-emitting element 31 and the light-sensitive element 32 of the optical feedback detection module 30; however, at least one light-blocking wall 40 can also be a single light-blocking wall 40 that is continuous in structure and integrally formed. Each light-blocking wall 40 can be made of black plastic or other materials with non-transparent (including visible light and invisible light) characteristics. Accordingly, at least one light-blocking wall 40 can prevent the mutual interference of optical signals between the blood glucose detection module 20 and the optical feedback detection module 30.

[0067] like Figures 1 to 2C As shown, the non-invasive blood glucose detection device 1 with the function of detecting the degree of fit of the wearer of the present invention further includes a packaging structure 50. The packaging structure 50 is disposed on the substrate, and the packaging structure 50 is used to package the blood glucose detection module 20 and the optical feedback detection module 30. The packaging structure 50 is applied to the substrate 10 with a packaging material so that the blood glucose detection module 20 and the optical feedback detection module 30 are completely covered by the packaging material, and then the packaging material is molded to form the packaging structure 50 in which the blood glucose detection module 20 and the optical feedback detection module 30 are buried. The aforementioned packaging material can be a transparent liquid optical glue or epoxy resin, but the present invention is not limited thereto. In one embodiment of the present invention, the height of the packaging structure 50 is greater than the height of the light source 21 and the light sensor 22 of the blood glucose detection module 20 and the height of the light emitting element 31 and the light sensing element 32 of the optical feedback detection module 30, so as to reserve space for setting the corresponding welding wires.

[0068] The non-invasive blood glucose detection device 1 with the function of detecting the degree of wearing fit of the present invention further includes a transparent cover plate 60. The transparent cover plate 60 is arranged on the packaging structure 50, and the transparent cover plate 60 is used to protect the blood glucose detection module 20 and the optical feedback detection module 30. The transparent cover plate 60 is made of transparent materials such as glass, but the present invention is not limited thereto. The transparent cover plate 60 can be fixed to the packaging structure 50 by gluing. Since the packaging material forming the packaging structure 50 itself has adhesive force, the transparent cover plate 60 can be adhesively fixed to the transparent cover plate 60 by the packaging material when the transparent cover plate 60 is arranged. The transparent cover plate 60 further includes a coating 61, and the coating 61 is formed on the side of the transparent cover plate 60 facing away from the substrate 10. By setting the coating 61, the transparent cover plate 60 can provide the effect of allowing light of a specific wavelength band to pass through, and can effectively block stray light of other unnecessary wavelength bands. Since the coating 61 is a structural design often used in existing cover plates, it will not be described in detail here.

[0069] After the packaging structure 50 and the transparent cover plate 60 are set, the at least one barrier 23 and the at least one light blocking wall 40 of the aforementioned blood glucose detection module 20 can be half-cut at the required position on the packaging structure 50 and the transparent cover plate 60 to form a groove, and a dispensing operation is performed to fill the groove with black glue, and the molding is completed after the glue is solidified. Since the aforementioned molding technology of the at least one barrier 23 and the at least one light blocking wall 40 is an existing technology, it will not be described in detail here.

[0070] In addition, Figures 1 to 2AAs shown, the non-invasive blood glucose detection device 1 with the function of detecting the degree of fit of the present invention further includes a processing unit 70. The processing unit 70 may be disposed on the substrate 10 or another independent substrate, and the processing unit 70 may also be an independent device. The processing unit 70 may be a component or device with a signal processing function such as a processor, a microcontroller or a computer. The processing unit 70 is electrically connected to the blood glucose detection module 20 to control the transmission of the light signal corresponding to each light source 21, and to process the light signal received by each light sensor 22 after being reflected by the skin, so as to perform the analysis of the result of the blood glucose detection. The processing unit 70 is also electrically connected to the optical feedback detection module 30 to control the transmission of the light signal corresponding to each light emitting element 31, and to process the light signal received by each light sensing element 32 after being reflected by the skin, so as to perform the analysis of the detection result of the degree of fit of the device.

[0071] In one embodiment of the present invention, the processing unit 70 mainly uses photoplethysmography (PPG) to analyze the light signal corresponding to at least one specific wavelength received by each photosensitive element 32 after being reflected by the skin, and determines the wearing fit of the device based on the PPG signal strength. When it is determined that the PPG signal strength exceeds a set value, it indicates that the surrounding area of ​​the corresponding photosensitive element 32 has a better wearing fit; conversely, when it is determined that the PPG signal strength does not reach the set value, it indicates that the surrounding area of ​​the corresponding photosensitive element 32 has a poor wearing fit. When it is determined that the device has a poor wearing fit, the processing unit 70 can notify the warning unit (not shown) electrically connected thereto, and send a sound, light, vibration or other types of warning signals through the warning unit to remind the user to re-wear the non-invasive blood glucose detection device 1 with wearing fit detection function of the present invention.

[0072] In the first embodiment of the present invention, the substrate 10 is in a square structure, the blood sugar detection module 20 is disposed in the first setting area 11 in the center of the substrate 10, and the optical feedback detection module 30 is disposed in the second setting area 12 of the outer rectangular frame area. The optical feedback detection module 30 can form a detection combination of one light emitting element 31 and two photosensitive elements 32 in each straight line portion of the second setting area 12. Accordingly, the wearing fit of the inner side of the edge 13 of the substrate 10 corresponding to each straight line portion can be detected by the two photosensitive elements 32 disposed at any two adjacent corners and the light emitting element 31 sandwiched in the middle, and then the overall configuration fit of the device can be detected by the symmetrical arrangement of the four photosensitive elements 32 and the four light emitting elements 31.

[0073] In addition, if Figure 2DAs shown, for the first embodiment of the present invention, the optical feedback detection module 30 further includes at least one blocking structure 33. Each blocking structure 33 is disposed between any light emitting element 31 and its adjacent light sensing element 32 to block any light emitting element 31 and its adjacent light sensing element 32. Each blocking structure 33 can extend from the edge 13 of the substrate 10 to connect to any light blocking wall 40. The at least one blocking structure 33 can also be made by a molding technology similar to the at least one blocking member 23 and the at least one light blocking wall 40 described above.

[0074] Please refer to Figure 3A and Figure 3B ,in Figure 3A is a top view of a second embodiment of the non-invasive blood glucose detection device with a wearing fit detection function of the present invention, Figure 3B For Figure 3A A top view of the optical feedback detection module of the second embodiment in which at least one barrier structure is added. Compared with the first embodiment, the present embodiment mainly changes the shape of the substrate and the locations of the light emitting elements and the light sensing elements of the optical feedback detection module. Figure 3A As shown, in this embodiment, the substrate 10 of the non-invasive blood glucose detection device 1a with the function of detecting the degree of wearing fit of the present invention is in a circular structure, the first setting area 11 is located in the center of the substrate 10, and the second setting area 12 forms an annular area located outside the first setting area 11. The optical feedback detection module 30 has 4 photosensitive elements 32 and 4 light-emitting elements 31, and the 4 photosensitive elements 32 are arranged at intervals of 90 degrees at the central angle of the circle in the annular area formed by the second setting area 12, and the 4 light-emitting elements 31 are respectively located in the middle position of two adjacent photosensitive elements 32, that is, any adjacent light-emitting elements 31 and photosensitive elements 32 are separated by a central angle of 45 degrees, so that the light-emitting elements 31 and the photosensitive elements 32 are symmetrically arranged based on the blood glucose detection module 20. As another example Figure 3B As shown, according to the second embodiment of the present invention, each barrier structure 33 is further disposed between any light emitting element 31 and its adjacent light sensing element 32 , and each barrier structure 33 extends from the edge 13 of the substrate 10 to any adjacent light blocking wall 40 .

[0075] Please refer to Figure 4A and Figure 4B ,in Figure 4A is a top view of a third embodiment of the non-invasive blood glucose detection device with a wearing fit detection function of the present invention, Figure 4B For Figure 4A A top view of the optical feedback detection module of the third embodiment of the present invention is provided with at least one barrier structure. Compared with the first embodiment, the present embodiment mainly reduces the number of the light sensing elements of the optical feedback detection module. Figure 4AAs shown, in this embodiment, the optical feedback detection module 30 of the non-invasive blood glucose detection device 1b with the function of detecting the wearing fit of the present invention has two photosensitive elements 32 and four light-emitting elements 31. The two photosensitive elements 32 are only arranged at the two diagonal positions of the rectangular frame area formed by the second setting area 12, while the four light-emitting elements 31 maintain the original setting positions, so that the light-emitting elements 31 and the photosensitive elements 32 are symmetrically arranged based on the diagonal lines of the blood glucose detection module 20. Accordingly, the optical feedback detection module 30 can form a detection combination of one light-emitting element 31 and one photosensitive element 32 in each straight line portion of the second setting area 12, and then the overall configuration fit of the detection device can be detected through the symmetrical arrangement of the two photosensitive elements 32 and the four light-emitting elements 31. As another example Figure 4B As shown, in the third embodiment of the present invention, each barrier structure 33 is further disposed between any light emitting element 31 and its adjacent light sensing element 32 , and each barrier structure 33 extends from the edge 13 of the substrate 10 to connect to any light blocking wall 40 .

[0076] Please refer to Figure 5A and Figure 5B ,in Figure 5A is a top view of a fourth embodiment of the non-invasive blood glucose detection device with a wearing fit detection function of the present invention, Figure 5B For Figure 5A A top view of a fourth embodiment of the optical feedback detection module in which at least one barrier structure is added. Compared with the second embodiment, the present embodiment mainly reduces the number of the light sensing elements of the optical feedback detection module. Figure 5A As shown, in this embodiment, the optical feedback detection module 30 of the non-invasive blood glucose detection device 1c with wearing fit detection function of the present invention has two photosensitive elements 32 and four light-emitting elements 31. The two photosensitive elements 32 are only arranged at intervals of 180 degrees at the central angle of the circle in the annular area formed by the second setting area 12, while the four light-emitting elements 31 maintain the original setting position, so that the light-emitting elements 31 and the photosensitive elements 32 are symmetrically arranged based on the diagonal line of the blood glucose detection module 20.
