Description

Technical Field

[0001] This utility model relates to the field of cochlear implant technology, and in particular to a monitoring system for reliability testing of cochlear implants. Background Technology

[0002] A cochlear implant is an extremely sophisticated medical device used to help deaf patients restore or improve their hearing. Because this device needs to be implanted in the body for a long period of time, high-quality materials, rigorous manufacturing processes, and comprehensive aging and validation processes are used to ensure that each implant meets the expected performance and safety standards.

[0003] In the high-temperature water bath test of cochlear implants, the current method uses a water tank control unit to control the water temperature of a certain number of implants to ensure the normal conduct of the water bath test. Management personnel need to record the temperature and process the data for each water tank. While this method can basically meet the initial reliability testing requirements, it has the following shortcomings: Low data recording efficiency: Existing methods often rely on manual recording of the temperature value in each water tank at regular intervals. This method is not only time-consuming and labor-intensive but also prone to human error; Lack of real-time monitoring capability: Traditional methods cannot achieve real-time monitoring of temperature changes in multiple water tanks; Difficult data analysis: Due to the scattered and inconsistent data formats, subsequent data analysis becomes complex, making it difficult to quickly and accurately assess the quality status of each batch of products. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides a monitoring system for reliability testing of cochlear implants, which mainly solves the technical problems existing in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0006] A monitoring system for reliability testing of cochlear implants includes a water tank and a heating rod inserted into the water tank. The system also includes multiple temperature acquisition terminals, a router, and a smart display terminal. Each temperature acquisition terminal includes a main control chip, a temperature sensor, a thermocouple connection circuit, and an output converter. The temperature sensor is used to acquire the water temperature in the water tank. The temperature sensor is connected to the output converter via the thermocouple connection circuit. The output converter is signal-connected to the main control chip. The main control chip is signal-connected to the smart display terminal via the router.

[0007] Optionally, the main control chip is an ESP32-PICO Wi-Fi chip, which is connected to the router via a 2.4G WiFi network. The smart display terminal is also connected to the router via the same 2.4G WiFi network.

[0008] Optionally, the main control chip is also connected to a personal terminal via a CH340G chip.

[0009] Optionally, the output converter is a MAX31856MUD+T chip.

[0010] Optionally, the temperature acquisition terminal also includes an LED indicator and a button, wherein the LED indicator and the button are respectively connected to the main control chip.

[0011] The beneficial effects of this invention are as follows: It sets up multiple temperature acquisition terminals, each located at the water tank. Each terminal uses a temperature sensor to collect the water temperature in the tank in real time and connects to an output converter via a thermocouple connection circuit. This converts the physical temperature signal into an electrical signal. The output converter then converts the weak electrical signal collected by the temperature sensor into a precise digital temperature reading. Cold junction compensation and linearity correction are also performed to improve measurement accuracy. This processed temperature data is then transmitted to the main control chip, which wirelessly communicates with the smart display terminal via a 2.4G WiFi network. After the temperature acquisition terminal uploads data, the smart display terminal updates and displays the temperature of each water tank in real time, while generating a temperature change curve for researchers to observe temperature fluctuations. Furthermore, users can view the current temperature data at any time and export historical data for further research and analysis. This is of great significance for verifying the stability and reliability of cochlear implants under different temperature conditions. Attached Figure Description

[0023] Please refer to the attached document. Figures 1 to 2 This application provides a monitoring system for reliability testing of cochlear implants. The monitoring system includes a water tank and a heating rod inserted into the water tank. The monitoring system also includes multiple temperature acquisition terminals 1, a router 2, and a smart display terminal 3. Each temperature acquisition terminal 1 includes a main control chip 101, a temperature sensor 102, a thermocouple connection circuit 103, and an output converter 104.

The main control chip 101 is signal-connected to the smart display terminal 3 through the router 2.

[0024] Specifically, the cochlear implant reliability testing and monitoring system provided in this application aims to ensure that the cochlear implant can pass a series of rigorous tests before long-term implantation in the human body, guaranteeing its performance and safety. The water tank simulates the human body environment, while the heating rod is responsible for adjusting the water temperature in the tank to the required standard temperature for high-temperature water bath testing. To accurately control and monitor the water temperature, multiple temperature acquisition terminals 1 are set up. Each temperature acquisition terminal 1 is located at the water tank, and each temperature acquisition terminal 1 includes a main control chip 101, a temperature sensor 102, a thermocouple connection circuit 103, and an input... The output converter 104 and temperature sensor 102 are responsible for real-time acquisition of the water temperature in the water tank. The temperature sensor 102 is connected to the output converter 104 via a thermocouple connection circuit 103, converting the physical temperature signal into an electrical signal. The output converter 104 then converts the weak electrical signal acquired by the temperature sensor 102 into a precise digital temperature reading, and also performs cold junction compensation and linearity correction to improve measurement accuracy. This processed temperature data is then transmitted to the main control chip 101. The main control chip 101 wirelessly communicates with the smart display terminal 3 via a 2.4G WiFi network. The WiFi network signal comes from router 2, with a frequency band between 2.400GHz and 2.485GHz. The intelligent display terminal 3 is mainly used for data visualization, storage, and further analysis. After the temperature acquisition terminal 1 uploads data, the intelligent display terminal 3 will update and display the temperature of each water tank in real time, and generate a temperature change curve to facilitate researchers to observe temperature fluctuations. In addition, users can view the current temperature data at any time and export historical data for more in-depth research and analysis. This is of great significance for verifying the stability and reliability of cochlear implants under different temperature conditions.

[0025] It should be noted that the technology of the intelligent display terminal 3 updating and displaying the temperature of each water tank in real time and generating a temperature change curve is a conventional technology in this field, which can be achieved using conventional application software. This embodiment will not be described in detail here.

The MAX31856MUD+T is a high-precision thermocouple-to-digital output converter used to read the temperature value of the thermocouple. The thermocouple is typically connected to the T+ and T- pins of the MAX31856MUD+T chip. In addition, the B IAS pin of the MAX31856MUD+T chip is connected to the negative terminal of the thermocouple to ensure that the thermocouple bias input is within the common-mode range.

[0029] Furthermore, the thermocouple connection circuit 103 typically includes a bias resistor and a filter capacitor. The bias resistor is usually added between the positive and negative terminals of the thermocouple to ensure the stability of the thermocouple output, while the filter capacitor is usually added to the T+ and T- pins of the MAX31856MUD+T chip to achieve filtering.

[0031] The ESP32-P I CO is a low-power system-on-a-chip (SoC) that integrates Wi-Fi and Bluetooth. It not only has powerful processing capabilities but also supports a rich set of peripheral interfaces, making it ideal for applications requiring wireless communication and complex data processing. GPIO21 and GPIO22 of the ESP32-P I CO are responsible for LED control. GPIO12, GPIO13, GPIO14, and GPIO15 are used as SDO, SDI, CS, and SCK respectively, electrically connected to the MAX318856MUD+T for data exchange via the SPI protocol. GPIO19 and GPIO38 are responsible for button 106 control, and U0TXD and U0RXD are responsible for serial communication with the CH340 chip.

[0032] In an optional implementation, the main control chip 101 is also connected to a personal terminal via a CH340G chip. The CH340G is a USB-to-serial communication chip, mainly used to enable data communication between a computer or other personal terminal with a USB interface and the main control chip 101.

[0033] Furthermore, the temperature acquisition terminal 1 also includes an LED indicator 105 and a button 106, the LED indicator 105 and the button 106 being signal-connected to the main control chip 101.

[0034] LED indicator lights 105 are connected to the main control chip 101 via signals. There are two LEDs, and their main function is to provide users with intuitive status feedback. For example, different colors or flashing patterns of LEDs can indicate the current working status of the system, such as normal operation, error occurrence, or data transmission status.
