Description

Technical Field

[0001] This invention relates primarily to the field of medical devices, and in particular to an intelligent detection device. Background Technology

[0002] In a healthy person, the pancreas automatically monitors blood glucose levels and secretes the necessary insulin / glucagon. However, in diabetic patients, the pancreas malfunctions and cannot secrete insulin as needed. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function and is a lifelong condition. Currently, medical technology cannot cure diabetes; it can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar levels.

[0003] Diabetic patients need to have their blood glucose levels checked before injecting insulin. Most current testing methods can continuously monitor blood glucose and send the data in real time to a remote device for user viewing; this method is called Continuous Glucose Monitoring (CGM). This method requires a testing device to be attached to the skin surface, with its probe inserted into the subcutaneous tissue fluid to complete the measurement.

[0004] However, currently, after the transmitter of the detection device is installed on the base, it is impossible to determine the degree of firmness of the connection between the transmitter and the base. If the connection between the transmitter and the base is too loose, the transmitter is prone to displacement or falling off, resulting in the loss of detection signal. Conversely, if the connection between the transmitter and the base is too tight, the electrical connection area between the transmitter and the sensor is prone to damage.

[0005] Therefore, existing technologies urgently need a detection device that can detect the transmitter's presence information to solve the above problems. Summary of the Invention

[0026] As mentioned earlier, after the transmitter of the existing detection device is installed on the base, it is impossible to determine the firmness of the connection between the transmitter and the base. If the connection between the transmitter and the base is too loose, the transmitter is prone to displacement or falling off, resulting in the loss of detection signal. Conversely, if the connection between the transmitter and the base is too tight, the electrical connection area between the transmitter and the sensor is prone to damage.

[0027] To address this problem, the present invention provides an intelligent detection device. After the transmitter is installed on the bottom shell, the in-situ detection module generates an in-situ detection signal, and the degree of firmness of the connection between the transmitter and the bottom shell is determined based on the in-situ detection signal.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments should not be construed as limiting the scope of the invention.

[0029] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not necessarily drawn to actual scale; for example, the thickness, width, length, or distance of some units may be enlarged relative to other structures.

[0030] The following description of exemplary embodiments is merely illustrative and is not intended to limit the invention or its application or use in any way. Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but where applicable, such techniques, methods, and apparatus should be considered part of this specification.

[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined or described in a figure, it will not need to be discussed further in the subsequent description of the figures.

[0032] Figure 1 This is a schematic diagram of the structure of the intelligent detection device according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the back of the transmitter in an embodiment of the present invention.

[0033] The intelligent detection device includes a base 10, a sensor 11, and a transmitter 12.

[0034] The base 10 is used to support the sensor 11 and the transmitter 12. The sensor 11 is disposed on the base 10, and the transmitter 12 is mounted on the base 10. Typically, the bottom surface of the base 10 also includes medical tape (not shown) for attaching the detection device to the skin surface.

[0035] The sensor 11 includes a probe 113 and a base 111. The probe 113 includes an external part (not shown in the figure) and an internal part (not shown in the figure). The internal part is inserted subcutaneously into the host to detect analyte parameters (such as blood glucose concentration, drug concentration, etc.) and generate corresponding electrical signals. The external part is bent relative to the internal part and laid flat on the base 111. The sensor 11 is mounted and fixed to the base 10 via the base 111.

[0036] The internal portion of the sensor consists of a substrate and at least two electrodes, namely a working electrode and a counter electrode, to form a two-electrode system. Preferably, the internal portion consists of a substrate and three electrodes, namely a working electrode, a counter electrode, and a reference electrode, to form a three-electrode system.

[0037] When the in vivo part consists of a substrate and three electrodes to form a three-electrode system, the external part includes conductive pins that correspond one-to-one with the three electrodes, so the number of pins is three.

[0038] The sensor 11 is also provided with a conductive adhesive strip 115 that contacts the pins. The conductive adhesive strip 115 includes at least two conductive areas and an insulating area. The conductive areas correspond one-to-one with the pins on the external part. Therefore, when the sensor 11 is a three-electrode system, the conductive adhesive strip 115 has at least three conductive areas and at least four insulating areas.

[0039] The transmitter 12 includes a transmitter housing 121 and internal circuitry (not shown in the figure), with the internal circuitry housed within the transmitter housing 121. The internal circuitry has at least two electrically insulated terminals 123. When the transmitter 12 is mounted on the base 10, the electrical terminals 123 are electrically connected to the pins on the external part of the sensor body via the conductive area of ​​the conductive adhesive strip 115. Preferably, as previously described, when the sensor 11 is a three-electrode system, there are three electrical terminals 123.

[0040] The bottom shell 10 is provided with a locking structure 103, and correspondingly, the transmitter housing 121 is provided with a buckle 1211 corresponding to the locking structure 103. Here, "corresponding" means that the number and position of the buckles 1211 and the locking structure 103 are consistent, so that the transmitter 12 is fixed to the bottom shell 10 by the buckle engagement of the buckles 1211 and the locking structure 103. Preferably, the locking structure 103 is provided on the side wall of the bottom shell 10, and the number is four. Correspondingly, the buckles 1211 are provided on the side wall of the transmitter housing 121, and the number is four.

[0041] In other embodiments of the present invention, the positions of the engaging structure 103 and the buckle 1211 may also be in other locations, and their number may be one, two, three, five, etc., without specific limitations here.

[0042] In this embodiment of the invention, the sensor 11 is further provided with an in-situ detection module 114. The in-situ detection module 114 includes a second physical component 1141, such as a voltage transformer, a magnetic component, an inductor, a capacitor, etc. It will be understood by those skilled in the art that the above physical components can also be used in combination, and the physical components that can be used in the in-situ detection module 114 are not limited to these. Other physical components that can trigger position signals can be used here.

[0043] Corresponding to the in-situ detection module 114, the transmitter 12 is provided with a first physical component 122. When the transmitter 12 is installed on the housing 10, the first physical component 122 and the second physical component 1141 are operably electrically connected. Here, "operable" electrical connection means that, depending on the type of the first physical component 122 and the second physical component 1141, they have different electrical connection methods.

[0044] Example 1

[0045] Piezoresistive devices

[0046] In this embodiment of the invention, the second physical component 1141 of the in-situ detection module is a piezoresistive device. The piezoresistive device is sensitive to pressure; changes in pressure exerted on it by external devices can cause changes in its resistance value. These changes can be linear or non-linear. This principle can be used to detect the firmness of the connection between the transmitter 12 and the base shell 10.

[0047] Figure 3 This is a schematic diagram of the in-situ detection module including a piezoresistive device according to an embodiment of the present invention. The second physical component 1141 is a piezoresistive device located on the sensor base 111. Correspondingly, the first physical component 122 on the transmitter is a rigid electrical contact. When the transmitter is installed on the base, the rigid electrical contact contacts the piezoresistive device. As those skilled in the art will know, in order to form a closed-loop circuit, there are two rigid electrical contacts, namely the first rigid electrical contact 122a and the second rigid electrical contact 122b.

[0048] In this embodiment of the invention, when the transmitter and the base are normally connected, the rigid electrical contact point contacts the piezoresistive device, generating a base pressure F1. Corresponding to this base pressure, the piezoresistive device generates a base resistance R1. When the connection between the transmitter and the base becomes loose and misaligned, the pressure generated by the rigid electrical contact point contacting the piezoresistive device decreases, for example, becoming F2. Obviously, F2 < F1, and the corresponding resistance value of the piezoresistive device becomes R2. If the piezoresistive device is a positive feedback device, then R2 < R1; conversely, if the piezoresistive device is a negative feedback device, then R2 > R1. When the connection between the transmitter and the base becomes tight, the pressure generated by the rigid electrical contact point contacting the piezoresistive device increases, for example, becoming F3. Obviously, F3 > F1, and the corresponding resistance value of the piezoresistive device becomes R3. If the piezoresistive device is a positive feedback device, then R3 > R1; conversely, if the piezoresistive device is a negative feedback device, then R3 < R1.

[0049] Regardless of whether the piezoresistive device is a positive feedback device or a negative feedback device, its resistance value has a unique correspondence with the pressure it is subjected to. The pressure it is subjected to is positively correlated with the firmness of the connection between the transmitter and the base. Therefore, the resistance value of the piezoresistive device indirectly characterizes the firmness of the connection between the transmitter and the base.

[0050] In a preferred embodiment of the present invention, the resistance value R of the voltage transformer device is converted into relative position data between the transmitter and the base after being processed by a relevant algorithm. The transmitter then wirelessly transmits the data to a remote device, such as a PDM (Personal Diabetes Manager) or a mobile terminal, so that the user can understand the tightness of the transmitter installation in real time.

[0051] In a preferred embodiment of the present invention, the voltage-transformer device is a voltage-transformer conductive adhesive strip. The voltage-transformer conductive adhesive strip is easy to cut and can be processed into any shape to meet the structural design requirements of the detection device.

[0052] Example 2

[0053] Magnetic components

[0054] In this embodiment of the invention, the second physical component 2141 of the in-situ detection module is a magnetic element that provides a stable magnetic field. At different effective distances, the magnetic element has different magnetic field directions and intensities. This principle can be used to detect the firmness of the connection between the transmitter and the base shell.

[0055] Figure 4This is a schematic diagram of the in-situ detection module including a magnetic component according to an embodiment of the present invention. The second physical component 2141 is a magnetic component, and correspondingly, the first physical component 222 on the transmitter is a magnetic sensing element. When the transmitter is installed on the base, the magnetic sensing element senses the direction or intensity of the magnetic field of the magnetic component, or simultaneously senses both the direction and intensity of the magnetic field. The direction or intensity of the sensed magnetic field varies depending on the distance O between the magnetic sensing element and the magnetic component. Preferably, the magnetic sensing element senses the magnetic field intensity H of the magnetic component.

[0056] In this embodiment of the invention, when the transmitter and the base shell are normally connected, the distance between the magnetic sensing element and the magnetic component is O1, and the magnetic sensing element senses the basic magnetic field strength H1 of the magnetic component. When the connection between the transmitter and the base shell becomes loose and misaligned, the distance between the magnetic sensing element and the magnetic component increases, for example, to O2, where O2 > O1, and the corresponding magnetic field strength sensed by the magnetic sensing element becomes H2, which is obviously H2 < H1. When the connection between the transmitter and the base shell becomes tight, the distance between the magnetic sensing element and the magnetic component decreases, for example, to O3, where O3 < O1, and the corresponding magnetic field strength sensed by the magnetic sensing element becomes H3, which is obviously H3 > H1.

[0057] Regardless of how the distance O between the magnetic sensing element and the magnetic component changes, there is a unique correspondence between the distance O and the magnetic field strength H. The distance between the magnetic sensing element and the magnetic component is related to the firmness of the connection between the transmitter and the base shell. Therefore, the magnetic field strength H of the magnetic component sensed by the magnetic sensing element indirectly characterizes the firmness of the connection between the transmitter and the base shell.

[0058] In a preferred embodiment of the present invention, the magnetic field strength H of the magnetic component sensed by the magnetic sensing element is converted into relative position data between the transmitter and the bottom shell after being processed by a relevant algorithm. The transmitter 12 then wirelessly transmits the data to a remote device, such as a PDM (Personal Diabetes Manager) or a mobile terminal, so that the user can understand the tightness of the transmitter installation in real time.

[0059] Example 3

[0060] Inductor

[0061] In this embodiment of the invention, the second physical component 3141 of the in-situ detection module is an inductor coil, and the inductance value L of the inductor coil can be calculated by the following formula:

[0062]

[0063] In the formula,

[0064] D is the diameter of the inductor coil;

[0065] l is the length of the inductor coil;

[0066] N is the number of turns in the inductor.

[0067] For the same inductor coil, its diameter D and number of turns N will remain unchanged, while its length l can change with the compressive or tensile forces at both ends. When its length l changes, its inductance value L will also change. This principle can be used to detect the firmness of the connection between the transmitter and the base shell.

[0068] Figure 5 This is a schematic diagram of the in-situ detection module including an inductor coil according to an embodiment of the present invention. The second physical component 3141 includes an inductor coil 3141a and a conductive boss 3141b. The conductive boss 3141b is located on the sensor base 311, and the inductor coil 3141a is electrically connected to the conductive boss 3141b. Correspondingly, the first physical component 322 on the transmitter includes a pressing member 322a that contacts one end of the inductor coil and an elastic electrical contact point 322b that is electrically connected to the other end of the inductor coil through the conductive boss 3142b. As those skilled in the art will know, in order to obtain the inductance value L of the inductor coil, the conductive boss 3141b, the pressing member 322a, and the elastic electrical contact point 322b are all made of conductive materials.

[0069] In this embodiment of the invention, when the transmitter and the base are normally connected, the pressing member 322a contacts one end of the inductor coil, and the elastic electrical contact 322b contacts the other end of the inductor coil. The pressing member 322a, the inductor coil, and the elastic electrical contact 322b form a closed circuit. The internal circuit inside the transmitter can obtain the inductance value L of the inductor coil. At this time, the distance between the transmitter and the base is s1, and the length of the inductor coil is l1. Corresponding to this length of the inductor coil, the basic inductance value of the inductor coil is L1. When the connection between the transmitter and the base becomes loose and misaligned, the distance between the transmitter and the base becomes s2. The pressing member 322a moves with the transmitter, and the length of the inductor coil becomes l2. Since s2 > s1 and l2 > l1, the inductance value of the inductor coil becomes L2. Obviously, L2 < L1. When the connection between the transmitter and the base becomes tighter, the distance between them becomes s3. The pressing element 322a moves with the transmitter, and the length of the inductor coil becomes l3, where s3 < s1 and l3 > l1. At this time, the inductance of the inductor coil becomes L3, which is obviously greater than L1. Regardless of the change in the distance between the transmitter and the base, since the elastic contact 322b is made of elastic material, it can maintain good electrical contact with the inductor coil unless the transmitter is completely detached from the base.

[0070] Regardless of how the length l of the inductor coil changes, there is a unique correspondence between the length l and the inductance value L. The length l of the inductor coil is related to the firmness of the connection between the transmitter and the base. Therefore, the inductance value L of the inductor coil indirectly characterizes the firmness of the connection between the transmitter and the base.

[0071] In a preferred embodiment of the present invention, the inductance value L of the inductor coil is converted into relative position data between the transmitter and the bottom shell after being processed by a relevant algorithm. The transmitter 12 then wirelessly transmits the data to a remote device, such as a PDM (Personal Diabetes Manager) or a mobile terminal, so that the user can understand the tightness of the transmitter installation in real time.

[0072] Example 4

[0073] capacitance

[0074] In this embodiment of the invention, the second physical component 4141 of the in-situ detection module includes the lower electrode of a capacitor. Correspondingly, the first physical component 422 includes the upper electrode 422a and an elastic electrical contact 422b of the capacitor. The upper electrode 422a and the lower electrode combine to form a complete capacitor. The elastic electrical contact 422b is used to make electrical contact with the lower electrode to form a closed circuit. The internal circuit in the transmitter can measure the capacitance value C of the capacitor. The capacitance value C of the capacitor can be determined by the following formula:

[0075]

[0076] In the formula: ε is a constant;

[0077] S is the area of ​​the upper and lower plates of the capacitor facing each other;

[0078] k is the electrostatic constant;

[0079] d is the distance between the upper and lower plates of the capacitor.

[0080] For a capacitor composed of upper and lower plates, its facing area S and electrostatic constant ε are constant and will not change. However, the distance d between the upper and lower plates can vary depending on the firmness of the connection between the transmitter and the base. When the distance d changes, the capacitance C also changes. This principle can be used to detect the firmness of the connection between the transmitter and the base.

[0081] Figure 6 This is a schematic diagram of the in-situ detection module of the present invention, including the lower electrode of a capacitor. As mentioned above, the first physical component 422 includes an upper electrode 422a and an elastic electrical contact 422b of the capacitor. The upper electrode 422a and the lower electrode combine to form a complete capacitor, and the elastic electrical contact 422b is used to make electrical contact with the lower electrode to form a closed circuit. Those skilled in the art will understand that the elastic electrical contact 422b is made of a conductive material in order to obtain the capacitance value.

[0082] In this embodiment of the invention, when the transmitter is normally connected to the base, the upper plate 422a and the lower plate form a capacitor. The elastic contact 422b contacts the lower plate, providing the lower plate with a charge opposite to that of the upper plate 422a. At this time, the distance between the upper plate 422a and the lower plate is d1, and the capacitance value of the capacitor is C1 corresponding to this distance. When the connection between the transmitter and the base becomes loose and misaligned, the distance between the transmitter and the base becomes d2, where d2 > d1, and the capacitance value of the capacitor becomes C2, which is obviously C2 < C1. When the connection between the transmitter and the base becomes tight, the distance between the transmitter and the base becomes d3, where d3 < d1, and the capacitance value of the capacitor becomes C3, which is obviously C3 > C1. Regardless of how the distance between the transmitter and the base changes, since the elastic contact 422b is made of elastic material, it can maintain good electrical contact with the inductor coil unless the transmitter is completely detached from the base.

[0083] Regardless of how the distance d between the upper and lower plates of the capacitor changes, there is a unique correspondence between the distance d and the capacitance value C. The distance d between the upper and lower plates is related to the firmness of the connection between the transmitter and the bottom shell. Therefore, the capacitance value C of the capacitor indirectly characterizes the firmness of the connection between the transmitter and the bottom shell.

[0084] In a preferred embodiment of the present invention, the capacitance value of the capacitor is converted into relative position data between the transmitter and the bottom shell after being processed by a relevant algorithm. The transmitter 12 then wirelessly transmits the data to a remote device, such as a PDM (Personal Diabetes Manager) or a mobile terminal, so that the user can understand the tightness of the transmitter installation in real time.

[0085] In the above embodiments, the internal circuit is also provided with a signal threshold range for when the transmitter is in normal position. Figure 7 This diagram illustrates the normal in-situ signal threshold range. The in-situ detection module may be one or a combination of several of the following: a piezoresistive device, an inductor, a magnetic component, or a capacitor. The relationship between its parameter signal and the strength of the connection between the transmitter and the base may be linear or non-linear, and may be positive or negative feedback. Regardless of the relationship, the parameter signal and the strength of the connection between the transmitter and the base are uniquely correlated. Therefore, the parameter signal has a unique maximum threshold and a unique minimum threshold. The interval between these maximum and minimum thresholds is the normal in-situ threshold range, within which the transmitter is normally fixed to the base.

[0086] If the parameter signal exceeds the normal in-position threshold range, it indicates that the transmitter has become loose, or that the transmitter is too tightly connected to the bottom shell due to external pressure. At this time, the internal circuit will issue an alarm signal, prompting the user to press the transmitter, replace the transmitter, or remove the external pressure.

[0087] To meet the needs of different users, the alarm signal can be designed to be one or a combination of light, vibration, and sound signals.

[0088] In other embodiments of the present invention, the second physical component of the in-situ detection module is located on the bottom shell 10, for example, on the upper bottom surface or side surface of the bottom shell 10.

[0089] Those skilled in the art will understand that different intelligent detection devices, or in-situ detection modules located in different positions, may have the same or different normal in-situ threshold ranges, and need to be calibrated before leaving the factory.

[0090] In summary, this invention discloses an intelligent detection device. After the transmitter is installed on the base shell, the internal circuit acquires an in-situ detection signal and compares it with a preset normal in-situ threshold range. If the signal exceeds this threshold range, the internal circuit issues a warning signal. The in-situ detection signal can determine the firmness of the connection between the transmitter and the base shell, allowing the user to take appropriate measures and enhancing the user experience.
