[0042] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0043] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the drawings only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the shape, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0044] The present invention provides a cochlear implant water bath test device. The device comprises a test container, a temperature acquisition unit, and a transmitter. The test container is used to hold a test solution. The temperature acquisition unit is used to collect temperature data of the test solution. The transmitter is communicatively connected to the cochlear implant, the temperature acquisition unit, and an electronic device, enabling the electronic device to display the status of the cochlear implant in real time during the water bath test, thereby resolving the technical problem in the prior art of being unable to accurately obtain cochlear implant test results.

[0045] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0046] Figure 1 Shown is a structural diagram of a cochlear implant water bath test device provided by an embodiment of the present application. Figure 1 As shown, the cochlear implant water bath test device provided in the embodiment of the present application includes a test container 11 , a temperature collection unit 12 , a transmitting unit 13 and a cochlear implant 14 .

[0047] The test container 11 is used to hold a test solution, and the cochlear implant 14 is located in the test solution for performing a water bath test.

[0048] For example, the test solution may be 0.9% saline.

[0049] The temperature collecting unit 12 is used to collect temperature data of the test solution during the water bath test and send the collected temperature data to the transmitting unit 13 .

[0050] In some embodiments, the temperature acquisition unit 12 is connected to the transmitting unit via SPI. The temperature acquisition unit 12 transmits the real-time collected temperature data to the transmitting unit 13 via a serial peripheral interface (SPI), and the transmitting unit 13 transmits the temperature data to the electronic device wirelessly.

[0051] Exemplarily, the temperature acquisition unit 12 includes a temperature collector 121 and a sensor 122. The sensor 122 is used to detect the temperature data of the test solution and send the temperature data to the temperature collector 121. The temperature collector 121 sends the received temperature data to the transmitting unit 13.

[0052] In some embodiments, the transmitting unit 13 is connected to the cochlear implant 14 by magnetic positioning coupling.

[0053] The transmitting unit 13 is coupled to the cochlear implant 14 through magnetic positioning, and is used to receive the impedance telemetry data sent by the cochlear implant 14 during the water bath test, and send the impedance telemetry data and the temperature data to the electronic device.

[0054] Impedance telemetry refers to the cochlear implant 14 measuring the impedance between its own electrodes according to the test instructions sent by the transmitting unit 13.

[0055] Exemplarily, the transmitter unit 13 is attached to the outside of the test container 11 and, through the magnetism of a magnet, magnetically couples the transmitter unit 13 to the cochlear implant 14 in the test solution. The specific location of the magnetic coupling between the transmitter unit 13 and the cochlear implant 14 can be determined by adjusting the position of the magnet.

[0056] In some embodiments, the apparatus further includes an insulation jacket 15, which is disposed over the upper and lower portions of the test container 11 to expose a test operation area located in the middle of the test container 11. The insulation jackets 15 disposed over the upper and lower portions of the test container 11 can improve the temperature stability of the test solution in the test operation area.

[0057] For example, according to the thermal insulation cover 15 provided on the test container 11, the specific position of the magnetic positioning coupling between the transmitting unit 13 and the cochlear implant 14 can be the middle of the test container 11 where there is no thermal insulation cover 15, which is convenient for observing the status of the cochlear implant 14 during the test and is more conducive to the magnetic positioning coupling between the cochlear implant 14 and the transmitting unit 13.

[0058] It should be noted that the above-mentioned arrangement of the insulation sleeves 15 at the upper and lower parts of the test container 11 is only for illustrative purposes. In actual applications, the insulation sleeves 15 can also be arranged at other positions of the test container 11 according to specific scenarios, and this application does not impose any restrictions on this.

[0059] The present invention provides a cochlear implant water bath test device, comprising a test container 11, a temperature acquisition unit 12, and a transmitter 13. The device also includes a cochlear implant 14. The transmitter 13 is communicatively connected to the cochlear implant 14, the temperature acquisition unit 12, and an electronic device to display the status of the cochlear implant 14 during the water bath test in real time on the electronic device, thereby reducing testing costs and improving the accuracy of the cochlear implant water bath test. The cochlear implant water bath test device provided in the present invention may also include a thermal insulation cover 15. By providing the thermal insulation cover 15 on the upper and lower portions of the test container 11, the temperature stability of the test solution in the test operation area is greatly improved, allowing the cochlear implant 14 to be kept at a suitable temperature for a long period of time during the water bath test, thereby improving the efficiency of the test.

[0060] Figure 2 Shown is a structural diagram of another cochlear implant water bath testing device provided by an embodiment of the present application.

[0061] like Figure 2 As shown, the device further includes a heating rod 161 , one end of which extends into the test solution for heating the test solution to maintain a stable temperature of the test solution.

[0062] Exemplarily, the device may further include a temperature controller 162 , which is connected to the heating rod 161 , wherein the temperature controller 162 and the heating rod 161 form a temperature control unit 16 .

[0063] Illustratively, when the test solution is lower than the test temperature, the temperature controller 162 drives the heating rod 161 to heat the test solution until the test solution reaches the test temperature, and the temperature controller 162 controls the heating rod 161 to stop heating the test solution.

[0064] Figure 3 The structure diagram of the transmitting unit provided by an embodiment of the present application is shown as follows: Figure 3The transmitting unit 13 includes: a power supply 131; a low-voltage dropout linear regulator 132, one end of the low-voltage dropout linear regulator 132 is connected to the power supply 131; a radio frequency integrated circuit 133, the radio frequency integrated circuit 133 is connected to the other end of the low-voltage dropout linear regulator 132; a serial peripheral interface 134, the serial peripheral interface 134 connects the wireless communication module 135 to one end of the radio frequency integrated circuit 133; a transmitting coil 136, the transmitting coil 136 is connected to the other end of the radio frequency integrated circuit 133.

[0065] Among them, the wireless communication module is, for example, ESP32-PICO, which is used to provide complete network functions for the cochlear implant water bath test device and to send the received impedance telemetry data and temperature data to the electronic device.

[0066] Here, LDO 5V-3V3 indicates that the LDO converts the 5V voltage into 3.3V, so that the transmitting unit 13 can obtain a stable and reliable power supply under various conditions.

[0067] The RFIC in the transmitting unit 13 cooperates with the transmitting coil 136 to enable efficient and reliable data transmission between the transmitting unit 13 and the cochlear implant 14 in the cochlear implant water bath test system.

[0068] Figure 4 The structure diagram of the cochlear implant 14 provided in one embodiment of the present application is shown. Figure 4 The cochlear implant 14 includes a receiving coil 141 , an implant chip 142 , and a stimulation output unit 143 .

[0069] When the cochlear implant 14 receives the test instruction sent by the transmitting unit 13 through the receiving coil 141, the implant chip 142 of the cochlear implant 14 performs forward stimulation test and impedance telemetry, detects through the stimulation output unit 143, and returns the impedance telemetry result to the transmitting unit 13.

[0070] Figure 5 Shown is a structural diagram of another cochlear implant water bath test device provided by one embodiment of the present application. Figure 5 As shown, the device includes: a test container 11, a temperature collection unit 12, a transmitting unit 13, a cochlear implant 14, a thermal insulation cover 15, a temperature control unit 16, a power supply 17, a router 18, and an electronic device 19.

[0071] In some embodiments, the device further includes a power supply 17 , and the power supply 17 is used to supply power to the transmitting unit 13 .

[0072] Exemplarily, when the power supply 17 supplies power to the transmitting unit 13, the cochlear implant water bath test device is in working condition. When the cochlear implant 14 is in a normal water bath test, the display screen or display device of the corresponding electronic device 19 displays the processing results of the temperature data and impedance telemetry data received in real time.

[0073] If the power supply 17 stops supplying power to the transmitting unit 13, the electronic device 19 will assume that the water bath test of the cochlear implant 14 has ended. At this time, the display screen or display device of the electronic device 19 will display the processing results of the temperature data and impedance telemetry data corresponding to the moment when the power supply 17 stopped supplying power to the transmitting unit 13. During the water bath test of the cochlear implant 14, whether the power supply 17 has a power failure can be determined based on the display of the processing results on the corresponding display screen or display device of the electronic device 19.

[0074] For example, during a water bath test on a cochlear implant 14, the temperature acquisition unit 12 is used to collect the temperature of the test solution in the test container 11 in real time and transmit the collected temperature data to the transmitting unit 13. The cochlear implant 14 performs a positive stimulation test and impedance telemetry according to the test instructions transmitted by the transmitting unit 13, and transmits the impedance telemetry results to the transmitting unit 13. The transmitting unit 13 wirelessly transmits the temperature data and impedance telemetry results to the electronic device 19 via the router 18. The electronic device 19 processes the received temperature data and impedance telemetry data and displays the processed results in real time.

[0075] Furthermore, during the water bath test of the cochlear implant 14, multiple cochlear implant water bath test devices can be deployed to perform water bath tests on each of the cochlear implants 14. Each cochlear implant water bath test device includes at least a test container 11, a temperature acquisition unit 12, a transmitter unit 13, a cochlear implant 14, a thermal insulation cover 15, a temperature control unit 16, a power supply 17, a router 18, and electronic equipment 19. Performing water bath tests on multiple cochlear implants 14 simultaneously improves test efficiency. During the water bath test of multiple cochlear implants 14, temperature data and impedance telemetry data can be transmitted over a network composed of the same router, saving network deployment costs and reducing testing costs.

[0076] For example, to improve the accuracy of water bath testing of cochlear implants 14, when water bath testing is performed on n cochlear implants 14, n corresponding cochlear implant water bath testing devices are required, namely cochlear implant water bath testing device 1 through cochlear implant water bath testing device n. Furthermore, each cochlear implant water bath testing device includes at least a test container 11, a temperature acquisition unit 12, a transmitter unit 13, a cochlear implant 14, a thermal insulation cover 15, a temperature control unit 16, and a power supply 17.

[0077] It should be noted that the n cochlear implant water bath test devices described above may use the same electronic device 19 or different electronic devices 19. If the n cochlear implant water bath test devices use the same electronic device 19, the display screen corresponding to the electronic device 19 may be divided into n display areas, with the processed results of the temperature data and impedance telemetry data of the corresponding cochlear implant water bath test device displayed in each display area.

[0078] The present application provides a structural diagram of another cochlear implant water bath test device, which includes a power supply 17, a router 18, and an electronic device 19. The power supply 17 is used to power the transmitting unit 13. The router enables the transmitting unit 13 to wirelessly transmit temperature data and impedance telemetry results to the electronic device 19. The electronic device 19 processes the received temperature data and impedance telemetry data and displays the processing results in real time, significantly reducing the frequency of removing the cochlear implant 14 for performance evaluation, effectively reducing the risk of potential damage to the cochlear implant 14 due to physical contact, and improving the accuracy of water bath testing of the cochlear implant 14. Wireless monitoring of the cochlear implant 14 enables relevant technicians to monitor the test status in real time, facilitating timely handling of any abnormal situations, and further improving the professionalism and efficiency of water bath testing of the cochlear implant 14.
