Description
The present invention mainly relates to the field of medical device, and in particular, to an intelligent detection device.
The pancreas in a normal person can automatically monitor the amount of glucose in the blood and automatically secrete the required dosage of insulin/glucagon. However, for diabetic patients, the function of the pancreas is abnormal, and the pancreas cannot normally secrete required dosage of insulin. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function and also a lifelong disease. At present, there is no cure for diabetes, but the onset and development of diabetes and its complications can be controlled by stabilizing blood glucose.
Patients with diabetes need to check their blood glucose before injecting insulin into the body. At present, many detection devices can continuously detect blood glucose, and send the blood glucose data to the remote device in real time for the user to view. This detection method is called Continuous Glucose Monitoring (CGM) . The method requires the detection device to be attached to the surface of the patient’s skin, and the sensor of the device to be inserted into the subcutaneous tissue fluid for testing.
However, at present, when the transmitter of the detection device is installed on the bottom case, the firmness of the combination between the transmitter and the bottom case cannot be judged, if the transmitter is loosely attached to the bottom case, the transmitter is likely to shift or fall off, resulting in losing of detection signal. On the other hand, if the transmitter is tightly attached to the bottom case , electric connection between transmitter and sensor area is easy to damage.
Therefore, the existing technology urgently needs an intelligent detection device that can detect the position information of the transmitter to solve the above problems.

FIG. 1 is a structural schematic diagram of the intelligent detection device in an embodiment of the invention. FIG. 2 is a structural schematic diagram of the back of the transmitter in an embodiment of the invention.
The intelligent detection device comprises bottom case 10, sensor 11 and transmitter 12.
The internal part of the sensor is composed of a substrate and at least two electrodes, which are the working electrode and the counter electrode respectively, to form a two-electrode system. Preferably, the internal part is composed of a base and three electrodes, which are working electrode, counter electrode and reference electrode respectively, to form a three-electrode system.
While the internal part consists of a base and three electrodes and constitutes a three-electrode system, the external part comprises conductive pins corresponding to the three electrodes one-to-one, so the number of pins is three.
The conductive tape 115 in contact with the pin is also provided on the sensor 11, the conductive tape 115 comprises at least two conductive and insulated area, and the conductive area corresponds to the pin of the external part one-to-one, so when the sensor 11 is three-electrode system, conductive tape 115 has at least three conductive areas, accordingly, there are at least four insulation areas.
A clamping structure 103 is provided on the bottom case 10. Correspondingly, a buckle 1211 corresponding to the clamping structure 103 is provided on the transmitter housing 121. Here, "corresponding" means that the number and position of the buckle 1211 and the clamping structure 103 are consistent, so that the transmitter 12 could be fixed on the bottom shell 10. Preferably, the clamping structure 103 is arranged on the side wall of the bottom case 10 with a quantity of four; correspondingly, the clamping buckle 1211 is arranged on the side wall of the transmitter housing 121 with a quantity of four.
In other embodiments of the invention, the clamping structure 103 and the buckle 1211 can also be located in other places, and the number of the clamping structure 103 and the buckle 1211 can also be one, two, three, five, etc., where no specific restriction is made.
In the embodiment of the invention, the sensor 11 is also provided with an in-position detection module 114, which comprises a second physical component 1141, such as a voltage variant resistance device, a magnetic part, an inductor coil, a capacitor, etc. It is understood by technical personnel in this field that the physical components mentioned above can also be combined. In addition, the physical components that can be used by the in-position detection module 114 are not limited to this, and other physical components that can trigger position signals can be used here.
The first physical component 122 is configured on transmitter 12 corresponding to the present detection module 114. When transmitter 12 is mounted on bottom case 10, the first physical component 122 is electrically operable with the second physical component 1141. The "operable" electrical connection here means that the first physical component 122 and the second physical component 1141 have different electrical connections according to the type of the first physical component 122 and the second physical component 1141.
First embodiment
Voltage variable resistance device
In the embodiment of the present invention, the second physical component 1141 of the in-position detection module is a voltage variant resistance device, which is sensitive to pressure, and the change of the external device's pressure on the voltage variant resistance device can cause the change of the resistance value of the voltage variant resistance device, which can be linear or nonlinear. This principle can be used to detect the firmness of the combination between transmitter 12 and bottom case 10.
FIG. 3 is a schematic diagram of an embodiment of the invention in -position detection module comprising a voltage transformer resistor. The second physical component 1141 is a voltage transformer device located on the sensor base 111, and the corresponding first physical component 122 on the transmitter is a rigid electrical contact point. When the transmitter is installed on the bottom case, the rigid electrical contact point contacts with the voltage transformer device. Technicians in this field can know that in order to form a closed loop circuit, the number of rigid electrical contact points is two, namely the first rigid electrical contact point 122a and the second rigid electrical contact point 122b.
In the embodiment of the invention, when the transmitter and the bottom case are normally connected, the rigid electrical contact point contacts with the voltage variant resistance device to generate a base pressure F1, and corresponding to the base pressure, the voltage variant resistance device generates a base resistance R1. When the connection between the transmitter and the bottom case becomes loose and lost the position, the pressure generated by contact between the rigid electrical contact point and the voltage variant resistance device decreases, for example to F2, apparently F2<F1, corresponding pressure variable resistance device resistance R2, if the voltage variant resistance device is a positive feedback device, the R2<R1, on the contrary, if the voltage variant resistance device is a negative feedback device, the R2>R1. When the connection between the transmitter and the bottom case becomes tight, the pressure generated by contact between the rigid electrical contact point and the varistor device is increased, for example F3, obviously the F3>F1, corresponding pressure variable resistance device resistance to R3, if the voltage variant resistance device is a positive feedback device, the R3>R1, on the contrary, if the voltage variant resistance device is a negative feedback device, the R3<R1.
Whether the voltage transformer device is a positive feedback device or a negative feedback device, there is a unique correspondence between the resistance value and the pressure, and the pressure is positively correlated with the firmness of the combination between the transmitter and the bottom case, so the resistance value of the voltage variant resistance device indirectly represents the firmness of the combination between the transmitter and the bottom case.
In the preferred embodiment of the invention, the resistance value R of the voltage variant resistance device is converted into the relative position data between the transmitter and the bottom case after being calculated by the relevant algorithm, and then transmitted wirelessly by the transmitter to a remote device, such as PDM (Personal Diabetes Manager) , mobile terminal, etc, it is convenient for users to know the tightness of the installation of the transmitter in real time.
In the preferred embodiment of the invention, the voltage variant resistance device is a voltage variable resistance conductive rubber strip, and the voltage variable resistance conductive rubber strip is easy to cut and can be processed into any shape to meet the structural design requirements of the testing device.
Second embodiment
Magnetic
In the embodiment of the invention, the second physical component 2141 of the in-position detection module is a magnetic component, which provides a stable magnetic field. At different effective distances, magnetic components have different magnetic field directions and magnetic field strengths. This principle can be used to detect the firmness of the combination between the transmitter and the bottom case.
FIG. 4 is a schematic diagram of an embodiment of the invention in -position detection module comprising a magnetic component. The second physical component 2141 is the magnetic component, and the corresponding first physical component 222 on the transmitter is the magnetic sensor. When the transmitter is mounted on the bottom case, the magnetic sensor inducts either the magnetic field direction or the magnetic field strength of the magnetic component, or both. The direction or strength of the induced magnetic field varies with the distance O between the magnetic sensor and the magnetic component. Preferably, the magnetic field strength H of the magnetic component induced by the magnetic sensor.
In the embodiment of the invention, when the transmitter is normally connected to the bottom case, the distance between the magnetic sensor and the magnetic component is O1, and the magnetic sensor senses the basic magnetic field strength H1 of the magnetic component. When the connection between the transmitter and the bottom case becomes loose and loses position, the distance between the magnetic sensor and the magnetic component becomes larger, for example, becomes O2, O2>O1, and the magnetic field strength of the magnetic component induced by the corresponding magnetic sensor becomes H2, obviously H2<H1. When the connection between the transmitter and the bottom case becomes tight, the distance between the magnetic sensor and the magnetic component becomes smaller, for example, O3, there O3<O1, and the magnetic field strength of the magnetic component that the corresponding magnetic sensor senses becomes H3, obviously H3>H1.
No matter how the distance O between the magnetic sensor and the magnetic component changes, there is a unique correspondence between the distance O and the magnetic field strength H , and the distance between the magnetic sensor and the magnetic component is related to the firmness of the transmitter and the bottom case, so the magnetic field strength H of the magnetic component induced by the magnetic sensor indirectly represents the firmness of the combination of the transmitter and the bottom case.
In the preferred embodiment of the invention, the magnetic field strength H of the magnetic component induced by the magnetic sensor is converted into the relative position data between the transmitter and the bottom case after the relevant algorithm operation, and then transmitted wirelessly to the remote device, such as PDM (Personal Diabetes Manager) , mobile terminal, etc., by the transmitter 12. It is convenient for users to know the tightness of the installation of the transmitter in real time.
Third embodiment
Inductance coil
In the embodiment of the invention, the second physical component 3141 of the in-position detection module is an inductor coil, and the inductance value L of the inductor coil can be calculated by the following formula:
In the formula,
D is the diameter of inductor coil;
l is the length of inductor coil;
N is the number of turns of inductor coil
For the same inductor coil, its diameter D and the number of turns N will not change, and the length l can vary depending on the extrusion force or the tensile force at both ends, when the length l changes, its inductance value L will also change. This principle can be used to detect the firmness of the combination between the transmitter and the bottom case.
FIG. 5 is a schematic diagram of the in-position detection module comprising inductor coil in an embodiment of the invention. The second physical component 3141 comprises 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 with the conductive boss 3141 b. Correspondingly, the first physical component 322 on the transmitter comprises a pressing part 322a in contact with one end of the inductor coil and an elastic electrical contact point 322b electrically connected with the other end of the inductor coil through conductive boss 3142b. What technicians in this field can know is that in order to obtain the inductance value L of the inductor coil, the conductive boss 3141 b, the pressing part 322a and the elastic electrical contact point 322b are all conductive materials.
In the embodiment of the invention, when the transmitter is normally connected to the bottom case, the pressing part 322a contacts one end of the inductor coil, and the elastic electrical contact point 322b contacts the other end of the inductor coil. The pressing part 322a, the inductor coil and the elastic electrical contact point 322b form a closed circuit, and the internal circuit in the transmitter can obtain the inductance value L of the inductor coil. At this time, the distance between the transmitter and the bottom case is s1, the length of the inductor coil is l1, corresponding to the length of the inductor coil, the basic inductance value of the inductor coil is l1. When the connection between the transmitter and the bottom case becomes loose and loses position, the distance between the transmitter and the bottom case becomes s2, the pressing part 322a moves with the transmitter, the length of the inductor coil becomes l2, s2>s1, l2>l1, and the inductance value of the inductor coil becomes L2, obviously L2<L1. When the connection between the transmitter and the bottom case becomes tight, the distance between the transmitter and the bottom case becomes s3, and the pressing part 322a moves with the transmitter, the length of the inductor coil becomes l3, s3<s1, l3>l1.
At this time, the inductance value of the inductor coil becomes L3, obviously L3>L1. Regardless of the distance between the transmitter and the bottom case, the elastic electrical contact 322b can maintain good electrical contact with the inductor coil because of its elastic material, unless the transmitter is completely removed from the bottom case.
No matter how the length l of the inductor coil changes, there is a unique correspondence between the length l and the inductor value L, while the length l of the inductor coil is related to the firmness of the combination between the transmitter and the bottom case. Therefore, the inductance value L of the inductor coil indirectly represents the firmness of the combination between the transmitter and the bottom case.
In the preferred embodiment of the invention, the inductance value L of the inductor coil is converted into the relative position data between the transmitter and the bottom case after being calculated by the relevant algorithm, and then transmitted wirelessly to a remote device, such as PDM (Personal Diabetes Manager) , mobile terminal, etc. It is convenient for users to know the tightness of the installation of the transmitter in real time.

The combination between the upper electrode plate 422a and the lower electrode plate is a complete capacitor, and the elastic electrical contact 422b is used to make electrical contact with the lower electrode plate to form a closed circuit. An internal circuit in the transmitter can measure the capacitance value C of the capacitor. The capacitance value C can be determined by the following formula:
In the formula,
ε is a constant;
S is the frontal area of the capacitor's upper and lower plates;
K is the electrostatic force constant;
D is the distance between the upper and lower plates of the capacitor.
For the capacitance composed of the upper and lower plates, the positive area S and the static power constant ε are fixed, and the distance d between the upper and lower plates can change with the firmness of the combination between the transmitter and the bottom case. When the distance D changes, the capacitance C will also change. This principle can be used to detect the firmness of the combination between the transmitter and the bottom case.
FIG. 6 is a schematic diagram of an embodiment of the present invention in situ detection module comprising a capacitor lower plate. As mentioned above, the first physical component 422 comprises a capacitive upper plate 422a and an elastic electrical contact 422b. The combination between the upper plate 422a and the lower plate is a complete capacitor, and the elastic electrical contact 422b is used to make electrical contact with the lower plate to form a closed circuit. Technicians in this field can know that elastic electrical contact 422b is a conductive material in order to obtain capacitance value.
In the embodiment of the invention, the transmitter and the bottom case are normally connected, the upper plate 422a and the lower plate form a capacitor, elastic electrical contact 422b is in contact with the lower plate and is used to provide the lower plate with a charge opposite to the upper plate 422a, the distance between the upper plate 422a and the lower plate is d1, corresponding to the upper and lower plate distance, the capacitance of the capacitor is C1. When the connection between the transmitter and the bottom case becomes loose and loses position, the distance between the transmitter and the bottom case becomes d2, d2>d1, and the capacitance value of the capacitor becomes C2, obviously C2<C1. When the connection between the transmitter and the bottom case becomes tight, the distance between the transmitter and the bottom case becomes d3, d3<d1, and then the capacitance value of the capacitor becomes C3, obviously C3>C1. Regardless of the distance between the transmitter and the bottom case, elastic electrical contact 422b can maintain good electrical contact with the inductor coil because of its elastic material, unless the transmitter is completely removed from the bottom case.
No matter how the distance d between the upper and lower plates of the capacitor changes, there is a unique corresponding relationship between the distance d and the capacitance value C, while the distance d between the upper and lower plates is related to the firmness of the combination between the transmitter and the bottom case. Therefore, the capacitance value C of the capacitor indirectly represents the firmness of the combination between the transmitter and the bottom case.
In the preferred embodiment of the invention, the capacitance value of the capacitor is converted into the relative position data of the transmitter and the bottom case after the relevant algorithm operation, and then transmitted wirelessly to the remote device, such as PDM (Personal Diabetes Manager) , mobile terminal, etc., so that the user can understand the installation tightness of the transmitter in real time.
In the embodiment, the internal circuit is also provided with a signal threshold interval with the transmitter normally in position. Fig. 7 is a diagram of the threshold interval of the normally in-position signal. The in-position detection module may be one or more combinations of voltage transformer devices, inductor coils, magnetic components or capacitors. The parameter signals and the bonding degree of the transmitter and the bottom case may be linear or nonlinear, and may be positive feedback or negative feedback. Whatever the relationship, the parameter signal is uniquely corresponding to the firmness of the bond between the transmitter and the bottom case, and thus the parameter signal has a unique maximum threshold and a unique minimum threshold, the interval between the above maximum threshold and minimum threshold is the normal in-place threshold interval, during which the transmitter is properly fixed to the bottom case.
If the parameter signal exceeds the normal in-position threshold range, it indicates that the transmitter is loose, or the transmitter is too tightly combined with the bottom case due to external extrusion. At this time, the internal circuit sends out an alarm signal, prompting the user to press the transmitter, or replace the transmitter, or cancel the external pressure.
In order to meet the needs of different users, the expression form of alarm signal can be designed as one or more combinations of luminous signal, vibration signal and sound signal.
In other embodiments of the present invention, the second physical component of the in-position detection module is located on the bottom case 10, for example on the upper bottom surface or side of the bottom case 10.

In conclusion, the invention discloses an intelligent detection device. When the transmitter is installed in the bottom case, the internal circuit obtains the in-position detection signal and compares it with the preset normal in-position threshold interval.
