Description

Technical Field

[0001] The present invention relates to a microelectronic information acquisition system, and in particular to a processing microsystem used for acquiring and monitoring wearing information on a dental appliance. Background Art

[0002] In Chinese patent CN107865663A, a wearable device for tooth attachment and a sensing device for tooth fixation are disclosed, and specifically disclosed: the wearable device for tooth attachment includes a sensing part for sensing the biological information of the patient, and a communication control part for storing the biological information sensed on the above-mentioned sensing part in data and sending the above-mentioned stored data. In addition, the above-mentioned sensing part includes a sensing head that contacts the tongue or gums of the patient, or is exposed inside the oral cavity, senses saliva or body temperature, and senses the biological information of the patient, and a sensor chip combined with the above-mentioned sensing head. In addition, at least one of a thermoelectric element, a piezoelectric element, a chemical substance detection element, and a marker sensor is equipped on the above-mentioned sensing head. In addition, the above-mentioned communication control part includes a data storage part that stores the biological information of the patient sensed by the above-mentioned sensing part in the form of data, and a data transmission part that remotely transmits the data stored in the above-mentioned data storage part. In addition, it also includes a monitoring part that displays the data sent by the above-mentioned data transmission part. In addition, in order to display the above-mentioned data, the above-mentioned monitoring part is equipped with at least a desktop computer, a laptop computer, and a smart phone as a display device for remote transmission. In order to prevent the sensor from being deformed by saliva, at least a part of the sensor is coated with a hydrophobic coating film. In addition, the wearable device for tooth attachment of the present invention is a wearable device for tooth attachment that forms a tooth attachment portion corresponding to the tooth shape of the tooth, including a sensor head that is exposed in the oral cavity after being combined with one side of the tooth attachment portion to sense the patient's body temperature, and a time measurement unit that uses the body temperature sensed on the sensor head to measure the attachment time of the tooth attachment portion on the tooth. In addition, the sensor head is equipped with a thermoelectric element, which generates electricity only at a set temperature, and the electricity generated by the thermoelectric element can be provided to the time measurement unit.

[0003] In the above patent, the sensor head 11, sensor chip 12 and communication control unit 20 of the sensor are installed on the tooth attachment part, and the three are electrically connected by wires (see the attached figure of the specification of patent CN107865663A). A wearable device, such as a transparent correction device, is used to sense the patient's body temperature and measure the attachment time of the wearable device on the teeth. However, in the above scheme, the sensor is indirectly installed on the wearable device or installed on the gums in an invasive way. If it is installed on a wearable device such as a dental brace, it will inevitably lead to a complex structure of the brace, and cause a strong foreign body sensation and discomfort to the wearer after wearing it. Moreover, it adopts a method in which three components (sensor head 11, sensor chip 12 and communication control unit 20) are separately set and electrically connected, and are set on the tooth attachment part. First, it will cause a serious foreign body sensation in the patient's mouth, and second, it is very likely that the electrical connection will fail due to the high humidity in the patient's mouth and cannot work. In addition, the wearing time detected by temperature will be affected by environmental factors, resulting in inaccurate detection data.

[0004] Chinese patent CN108784859A discloses a dental correction system, including a dental brace (such as invisible braces), a (passive) radio frequency tag and a card reader; the dental brace and the radio frequency tag can be placed inside the oral cavity, and the card reader can be placed outside the oral cavity. The radio frequency tag further includes an IC chip, a power supply circuit, a contact device and an adjustment resistor; the IC chip, the power supply circuit and the adjustment resistor are located inside the dental brace; the contact device is placed on the surface of the dental brace (preferably the tongue side) that contacts the teeth, and is connected in parallel with the adjustment resistor; the contact device includes a first contact and a second contact that are not in contact connection, and when all or part of the first contact and the second contact contact the tooth surface, the first and second contacts can form an electrical connection; the contact device and the adjustment resistor are used to control the power supply circuit to supply power to the IC chip when receiving a read signal from the card reader... and the card reader reads the information of the radio frequency tag at every fixed time T0 (for example, every 10 minutes, or at non-fixed time), and records the read status information Si; the status information can be used to determine the wearing time T of the dental brace.

[0005] The above patents have the following technical problems: First, the information on the wearing status of the braces depends on the card reader device that is carried around the body all day outside the oral cavity, and the radio frequency tag is continuously read to achieve the purpose of effectively collecting complete data. The long-term close-fitting use of radio frequency tags and card readers based on radio frequency technology will directly threaten the health of the wearer with its electromagnetic radiation. Second, the above patents use passive radio frequency tags, and the volume of passive radio frequency tags is in the order of centimeters, that is, the volume of the passive radio frequency tags in the above patents is more than 10mm, at least more than 8mm. Then the above patent installs the passive radio frequency tag in the dental braces, and the contacts are installed on the surface of the dental braces (preferably the tongue side) that contacts the teeth. In this way, it is necessary to redesign the shape of the dental braces, and leave a position for the installation chamber for the radio frequency tag in the braces, which will further cause the tongue side of the braces to have a protruding protrusion protruding outward, causing the patient to have a serious foreign body sensation in the oral cavity, greatly affecting the wearing experience, and may even cause the patient to wear it frequently and affect the correction effect. In addition, since it is necessary to set up an installation chamber for installing a passive radio frequency tag in the corrector, the installation effect of the corrector and one of the orthodontic accessories on the teeth will inevitably be sacrificed, which may cause the force effect of the corrector to be less than expected and affect the correction effect. Third, passive radio frequency tags are generally used for close-range contact identification. Passive radio frequency tags operate in the low-frequency bands of 125KHz, 13.56MHz, etc., and their typical applications include: bus cards, second-generation ID cards, canteen meal cards, etc. The above patent uses the card reader as both a charging device for passive radio frequency tags and an information reading device. Then the card reader must be set close to the radio frequency tag. If the distance is a little far, neither charging nor information reading can be achieved. In the comparative document, the card reader is installed on the mobile terminal, which will cause the card reader to be unable to charge the passive radio frequency tag in time, resulting in its inability to collect wearing information. It will also cause information collection failure due to the long distance, so that the wearing information obtained by the doctor is inaccurate. Summary of the invention

[0006] The purpose of the present invention is to provide a micro system for collecting, monitoring and processing wearing information of a micro dental appliance.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented as follows: a microsystem for collecting, monitoring and processing wearing information of a dental appliance, characterized in that it includes a microsystem information collection device, an external wireless charging device and an information reading and processing device; wherein the microsystem information collection device includes a micromechanical pressure sensor, an information processing IC chip and a wireless charging receiving module, and the microsystem information collection device is installed on the tooth surface as a mounting bump of the dental appliance. In the above manner, the information collection device is installed on the wearer's teeth as an orthodontic accessory (i.e., a bump) of the appliance. After the wearer wears the appliance, the groove on the appliance that originally cooperates with the orthodontic accessory cooperates with the information collection device, and the micromechanical pressure sensor on the information collection device is pressurized and transmits the signal to the information processing IC chip for storage. The external wireless charging device only wirelessly charges the microsystem information collection device to ensure real-time monitoring when wearing the appliance, thereby improving the accuracy of the monitoring information. After the wearer has undergone a period of correction (e.g., two to eight weeks), when the wearer goes to the hospital for a follow-up visit, the doctor can use the information reading and processing device to read the wearing time information collected by the information collection device, and plan the wearer's next correction cycle based on the collected information. In addition, in the above manner, the microsystem information collection device is attached to the tooth surface just like a general orthodontic accessory, which will not affect the wearer's comfort and aesthetics at all, and can ensure the accuracy and stability of information collection.

[0008] To further realize wireless charging of the microsystem information acquisition device, the wireless charging receiving module includes a wireless charging receiving circuit connected to the information processing IC chip and the pressure sensor, and the wireless charging receiving circuit includes a capacitor C and a receiving inductor.

[0009] In order to further monitor the wearing status in real time, the information processing IC chip is integrated with a non-volatile memory, and the information processing IC chip includes a real-time acquisition control module, a real-time clock module, a non-volatile storage module and a serial port module; the real-time acquisition control module acquires the wearing status information of the dental braces sensed by the micromechanical pressure sensor in real time through the key port, and writes the time information of the real-time clock module into the non-volatile storage module.

[0010] In order to further improve the monitoring accuracy, the internal circuit of the key port of the information processing IC chip has a pull-up function.

[0011] Wireless charging of a microsystem information acquisition device is realized, wherein the peripheral wireless charging device includes a wireless charging transmitting module, the wireless charging transmitting module includes a wireless charging transmitting circuit, the wireless charging transmitting circuit includes a power supply and a rectifier circuit connected to the power supply, and a transmitting inductor connected to the power supply and the rectifier circuit.

[0012] Preferably, the information reading and processing device includes a card reader and a PC terminal, and can also be a mobile phone terminal or other reading devices, smart device terminals.

[0013] To further improve comfort, the thickness of the information acquisition device is no more than 1.5 mm.

[0014] To further improve comfort, the length x width x thickness of the information acquisition device is not greater than 5mm x 4mm x 1.5mm.

[0015] Beneficial effects:

[0016] The present invention is used for the micro-system for collecting, monitoring and processing the wearing information of the dental appliance. The micro-information collection device is installed on the wearer's teeth as an orthodontic accessory (i.e., a bump) of the appliance. After the wearer wears the appliance, the groove on the appliance cooperates with the information collection device and collects and monitors the wearing information through the sensor. The micro-system information collection device can be charged through an external wireless charging device to ensure real-time monitoring when the appliance is worn, thereby improving the accuracy of the monitoring information. After the wearer has undergone a period of correction (such as two to eight weeks), when the wearer arrives at the hospital for a follow-up visit, the doctor can use the information reading and processing device to read the wearing time information collected by the information collection device, and can plan the wearer's next cycle of correction based on the collected information. Moreover, by using the system of the present invention, the micro-system information collection device is attached to the tooth surface just like a general orthodontic accessory, which will not affect the wearer's comfort and beauty at all, and will not affect the doctor's operating habits, and can ensure the accuracy and stability of information collection.

[0017] In addition, the space in the human oral cavity is narrow, and the skin of the tongue and other parts is sensitive, so foreign objects of excessive size in the oral cavity may cause discomfort to the patient, and the patient may reduce the wearing time due to the discomfort, thereby affecting the correction effect. Compared with the existing dental appliance wearing time monitoring equipment, the scheme of the present invention adopts an integrated microsystem information acquisition device composed of a built-in information processing IC chip (non-volatile memory), a pressure sensor and a wireless charging receiving circuit (a capacitor C with a small capacity and a small volume), so that it can be the same size as an orthodontic accessory (thickness less than 1.5mm, length and width are not more than 5mm), and truly realizes a "miniature" monitoring and processing microsystem. The wearer has no discomfort, ensuring the patient's wearing time during the correction cycle, thereby improving the correction effect. Moreover, the microsystem information acquisition device in the present invention adopts a built-in information processing IC chip (non-volatile memory), which is powered by an external device, and can collect wearing information for a long time, until the doctor uses an information reading and processing device to read the information during the return visit before rewriting. Therefore, information can be stored reliably for a long time, and the danger caused by the built-in power supply or wires in the mouth and the health impact caused by the radiation generated by the radio frequency tags set in the mouth can be avoided.

[0021] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings, but the present invention is not limited to these implementation modes, and any improvement or substitution based on the basic spirit of the present embodiment still falls within the scope of protection required by the claims of the present invention.

[0022] Example: Figure 1-3 As shown, this embodiment provides a microsystem for collecting, monitoring and processing wearing information of a dental appliance, including a microsystem information collection device, an external wireless charging device and an information reading and processing device; the microsystem information collection device is installed on the tooth side of the wearer to collect the wearing time information of the dental appliance, and the external wireless charging device is used to wirelessly charge the microsystem information collection device to support its normal operation. The information reading and processing device is used to obtain the data information collected by the microsystem information collection device for the doctor's reference.

[0023] Among them, the microsystem information acquisition device is block-shaped and is pre-installed on the wearer's teeth. The installation method in this embodiment adopts the method of pasting. And the microsystem information acquisition device can be installed on the lip side or tongue side of the wearer, and can be installed on any molar of the wearer. In this embodiment, the microsystem information acquisition device is installed on the tongue side of the wearer's molars or molars, and the microsystem information acquisition device in this embodiment is pasted on the tooth surface as an orthodontic accessory for installing a dental brace, and the outward protrusion cooperates with the groove on the dental brace. Therefore, the size of the microsystem information acquisition device in this embodiment is consistent with the size of a general orthodontic accessory. Its thickness generally does not exceed 1.5mm, and the length x width x height of the microsystem information acquisition device in this embodiment is basically not more than 5mmx4mmx1.5mm.

[0024] The external wireless charging device can be configured as an accessory or other device that is convenient for the wearer to carry and is within the effective charging range, such as a necklace, earrings, ear hooks, headwear, or an accessory that can be clipped on a collar.

[0025] The information reading device is generally a card reader and a PC terminal, and a mobile phone can also be used as a data reading terminal.

[0026] Figure 1 The internal structure diagram of the microsystem information acquisition device in this embodiment includes an information processing IC chip, a micromechanical sensor pressure switch and a wireless charging receiving module. Among them, the information processing IC chip is the non-volatile storage chip with the lowest power consumption in the world, with a standby current of 3-6μA and a working current of 0.1mA-0.5mA. The wireless charging receiving module includes a wireless charging receiving circuit, and the wireless charging receiving circuit includes a capacitor C and a receiving inductor. After receiving the wireless charging, the capacitor supplies power to the information processing IC chip. Once the wearer puts on the dental braces, the dental braces will contact the microsystem information acquisition device, the micromechanical sensor pressure switch will feel the pressure from the braces, and the information processing IC chip will start to collect wearing time information.

[0027] The peripheral wireless charging device includes a wireless charging transmitting circuit of a wireless charging transmitting module. Specifically, the wireless charging transmitting circuit includes a micro power supply, the positive electrode of the micro power supply is connected to a rectifier circuit, the rectifier circuit is composed of 4 diodes in series, and the rectifier circuit and the negative end of the micro power supply are connected to a transmitting inductor. Wireless charging is achieved through the transmitting inductor and the receiving inductor. Among them, the volume and capacity of the capacitor C in this embodiment are relatively small, and the volume of the capacitor C is 1-2mm in size. In this embodiment, the volume of the capacitor C is 1mm. The peripheral wireless charging device is configured to charge the microsystem information acquisition device at regular intervals, and each charging time is only a few seconds. After each charging, the microsystem information acquisition device immediately works and discharges naturally, and can be used continuously for more than tens of minutes (such as 45 minutes). The peripheral wireless charging device can charge the wireless charging receiving module of the microsystem information acquisition device for more than 30 times. When the wearer eats or removes the dental braces, the peripheral wireless charging device can be removed and charged at the same time.

[0028] Figure 2 The figure is the internal structure diagram of the information processing IC chip, which is composed of a real-time acquisition control module, a real-time clock module, a non-volatile storage module, and a serial port module. The real-time acquisition control module acquires the wearing status information of the dental braces in real time through the key port, and writes the time information of the real-time clock module into the non-volatile storage module. When the amount of information collected reaches a certain level, the doctor can use the card reader to extract the data collected and stored in the non-volatile storage module through the serial port module for comprehensive analysis between doctors and patients.

[0029] Specifically, the micromechanical sensor pressure switch is used to collect the wearing status of the dental braces: when the dental braces are in the normal wearing state, the micromechanical sensor switch is in the closed state, and the logic state of the key port of the input information processing IC chip is 0; when the dental braces are in the non-wearing state, the micromechanical sensor switch is in the open state, and the logic state of the key port of the input information processing IC chip is 1, wherein the internal circuit of the key port of the information processing IC chip has a pull-up function. The information processing IC chip monitors the wearing status of the dental braces in real time through the key port: when the dental braces in the wearing state fall off or are normally removed, the information processing IC chip will collect a falling edge signal at the key port, and the information processing IC chip will record the information of the event, that is, save the data of the event information in the non-volatile memory integrated inside the information processing IC chip; when the dental braces are restored from the non-wearing state to the wearing state, the information processing IC chip will collect a rising edge signal at the key port, and the information processing IC chip will record the information of the wearing action event, that is, save the data of the wearing action event information in the non-volatile memory integrated inside the information processing IC chip.

[0030] Figure 3 The information extraction and analysis device of the dental brace information collection system includes an information processing IC chip, a card reader and a PC (which can also be a mobile phone or other reading device). The information processing IC chip and the card reader are connected through the serial port clock terminal SCK, the serial port data input terminal SDI, the serial port data output terminal SDO and the serial port read / write mode control terminal R / W. When MODE is connected to GND, the card reader can actively initiate an access operation to the information processing IC chip, that is, the data can be read and written to the non-volatile storage module of the information processing IC chip through the serial port. When the dental brace wearing status information has been collected and saved in the information processing IC chip, the data extracted by the card reader can be used for further comprehensive analysis by the user. The card reader and the PC can be connected through a universal interface (such as a USB interface, a UART interface, etc.). On the PC, mobile phone or other smart device end, with the help of application software, the card reader and the information processing IC chip can be operated more conveniently.

[0031] The microsystem for collecting, monitoring and processing wearing information of dental braces of this embodiment installs the miniaturized information collection device as an orthodontic accessory (i.e., a bump) of the braces on the wearer's teeth. When the wearer wears the braces, the groove on the braces cooperates with the information collection device and collects and monitors the wearing information through the sensor. The microsystem information collection device can be charged through an external wireless charging device to ensure real-time monitoring when wearing the braces and improve the accuracy of the monitoring information. After a period of correction (such as two to eight weeks), when the wearer arrives at the hospital for a follow-up visit, the doctor can use the information reading and processing device to read the wearing time information collected by the information collection device, and can plan the wearer's next cycle of correction based on the collected information. Moreover, using the system of this embodiment, the microsystem information collection device is attached to the tooth surface just like a general orthodontic accessory, which will not affect the wearer's comfort and beauty at all, and will not affect the doctor's operating habits, and can ensure the accuracy and stability of information collection.

[0032] In addition, the space in the human oral cavity is narrow, and the skin of the tongue and other parts is sensitive, so foreign objects of excessive size in the oral cavity may cause discomfort to the patient, and the patient may reduce the wearing time due to the discomfort, thereby affecting the correction effect. Compared with the existing dental appliance wearing time monitoring equipment, the scheme of the present invention adopts an integrated microsystem information acquisition device composed of a built-in information processing IC chip (non-volatile memory), a pressure sensor and a wireless charging receiving circuit (a capacitor C with a small capacity and a small volume), so that it can be the same size as an orthodontic accessory (thickness less than 1.5mm, length and width are not more than 5mm), and truly realizes a "miniature" monitoring and processing microsystem. The wearer has no discomfort, ensuring the patient's wearing time during the correction cycle, thereby improving the correction effect. Moreover, the microsystem information acquisition device in the present invention adopts a built-in information processing IC chip (non-volatile memory), which is powered by an external device, and can collect wearing information for a long time, until the doctor uses an information reading and processing device to read the information during the return visit before rewriting. Therefore, information can be stored reliably for a long time, and the danger caused by the built-in power supply or wires in the mouth and the health impact caused by the radiation generated by the radio frequency tags set in the mouth can be avoided.
