Technical Field

[0001] The invention relates to the field of otolaryngology medical instruments, and more particularly to an ear vagus nerve stimulator testing device. Background Art

[0002] The vagus nerve is the longest and most widely distributed nerve in the cranial nerves. Early studies have found that treatment of the vagus nerve has a certain effect on hypertension, diabetes, drug-resistant epilepsy and depression. Modern anatomy believes that the vagus nerve has a branch in the external ear, namely the auricular branch of the vagus nerve, which is mainly distributed in the external auditory canal and the concha area. Figure 1 A (external auditory canal opening) and B (concha area) are the ear acupoints of the vagus nerve. By electrically stimulating the acupoints A and B, the stimulation reaches the solitary nucleus of the vagus nerve through the neural pathway, thereby achieving the effect of electrical nerve stimulation treatment.

[0003] The existing ear vagus nerve stimulator is mainly composed of two parts: the main unit and the ear electrode. The ear electrode of the ear vagus nerve stimulator is provided with two electrode contacts in the auricle area and the external auditory canal to form a stimulation circuit to achieve a therapeutic effect. In order to ensure that the ear vagus nerve stimulator can work safely and effectively, it is very important and necessary to test the performance and effect of this device. At the same time, multi-mode testing is required for batch testing to quickly select unqualified products and improve the detection efficiency. Therefore, according to actual needs, there is a need for a test device with simple structure, easy operation, reliable electrical connection, and batch detection. Summary of the invention

[0004] In order to solve the problem of accuracy of the performance and effect of an ear vagus nerve stimulator, the present invention provides an ear vagus nerve stimulator testing device.

[0005] The invention comprises: at least one test fixture and a control terminal, wherein the test fixture comprises: an upper shell structure, a lower shell structure and a circuit board located between the upper shell structure and the lower shell structure, wherein the upper shell structure has an earplug slot, an auricle connecting male head, a host connecting male head and a conductive ring located in the earplug slot; the conductive ring, the auricle connecting male head and the host connecting male head are all conductively connected to the circuit board; the conductive ring, the auricle connecting male head and the host connecting male head obtain the ear vagus nerve stimulation signal and transmit it to the circuit board, which is then sent to the control terminal through the circuit board. The above device can quickly and accurately detect the performance and effect of the ear vagus nerve stimulator, thereby judging whether it is qualified, and improving the qualified rate of the product.

In this embodiment, a test board 300 is further included, and the test fixture 100 is installed on the test board 300. A plurality of test fixtures 100 can be installed on the test board 300 at the same time, wherein the number of test fixtures 100 can be arranged in an array as required. For example, 10 test fixtures are installed in this embodiment.

[0021] Specifically, the upper and lower shell structures are made of insulating material, preferably nylon. Figure 6a and Figure 6b As shown, the upper and lower shell structures are fixed and limited by four pairs of standard cross cylindrical head screws 180 and hexagonal nuts 190. The upper shell structure is provided with an auricle slot 140, a host slot 145, and a circuit board mounting slot 146; the circuit board mounting slot is used to fix and limit the circuit board 130, and a hexagonal nut mounting slot is reserved in the middle part of the upper shell structure for fixing and limiting the circuit board and the fixing parts in the lower shell structure.

[0023] like Figure 8aAs shown, the conductive ring 170 adopts a hollow cylindrical structure, which is used to fix and limit the earplug electrode. The hollow design of the middle part of the conductive ring 170 can increase the contact area between the conductive ring and the earplug electrode, effectively improving the current transmission efficiency and stability. The conductive ring is made of conductive material, and copper is preferred to ensure high conductivity. Figure 8b Schematic diagram of the installation of a conductive ring of an ear vagus nerve stimulator testing device according to an embodiment of the present invention.

[0024] like Fig. 9 As shown, the conductive ring 170 also includes a conductive ring fixing member 171 disposed on the lower shell structure, which is made of insulating material, preferably nylon. A conical groove base structure 172 is provided at the left end of the conductive ring fixing member 171. Figure 8b As shown, the conductive ring 170 is installed in the conductive ring fixing part. When the earplug electrode is inserted into the conductive ring, the conical groove base structure 172 makes the top of the earplug electrode fit and fix the groove to effectively prevent the displacement of the earplug electrode. A square protruding screw mounting hole structure 173 is provided at the right end for fixing and limiting the conductive ring fixing part.

[0025] like Fig.10 As shown, the circuit board is provided with a male connector 181 for connecting to the signal of the test board; an annular conductive area 174 is provided to ensure the electrical continuity of the circuit board so that the current transmitted by the auricle electrode can flow smoothly through the circuit board, and copper is preferably used as the material. The circuit board is provided with a host connector male connector extending from the side of the host storage slot, which is connected to the host for signal connection, and is used to read the host serial number and control the working mode of the host.

[0026] The test fixture is connected to the earplug electrode of the ear electrode through a conductive ring, and the annular conductive area on the circuit board is connected to the auricle electrode of the ear electrode to form a test loop, thereby effectively testing the output performance of the ear electrode. Figure 3 The test board and the control terminal can transmit signals by wire or wirelessly. The test board is also provided with a female connector 300, the number of which is set according to actual needs, for connecting with the male connector of the test fixture.

[0027] The test board is also provided with an electrode output terminal for connecting an external test device, so that the circuit board can transmit electrical signals with the external test device. A screw mounting hole is reserved at the right end, and the circuit board can be firmly installed in the upper and lower shell structures through the upper shell nut and the lower shell screw to ensure the firmness and stability of the circuit board.

[0028] The indicator light 148 is used to indicate whether the output of the product is normal.

[0029] The switch 147 is used to control the on and off of the circuit.

[0030] Continue to refer Figure 3 The control terminal 200 is provided with a signal receiving module 210, a data analysis module 220, a data determination module 230, a data storage module 240, a data display module 250, a monitoring module 260, the monitoring module receives the host serial number information, and a mode switching module 270. The control terminal receives, analyzes, and determines whether the electrode output signal is normal, and the data display module displays some main parameter values ​​and determination results of the electrode output through a display screen.

[0031] For batch testing of multiple products, multiple test fixtures are controlled simultaneously through the control terminal. The electrode output signal on each test fixture is connected to the control circuit of the control terminal. The output parameters are analyzed and judged, and the indicator light on the test fixture is used to determine whether it is qualified. The control terminal can switch modes. After a certain mode data is tested, it can switch to the next mode for data measurement. The tested data is analyzed and judged. If it is unqualified, the information will be transmitted to the test fixture and displayed through the indicator light. At the same time, the display screen can also display relevant data information. The test and analysis data are stored in the storage module. The mode switching can be manual or automatic.

[0032] Compared with the prior art, the beneficial effects of the patent of the present invention are: 1. The test device for the ear vagus nerve stimulator provided, by designing the circuit board and the test device as a layered assembly structure in the test device, can replace the circuit board at any time according to the test requirements, which can effectively improve the test efficiency and reduce the test cost; 2. By arranging the conductive ring fixing part on the back of the lower shell, it is convenient to disassemble and replace the conductive ring used for testing, thereby improving the test efficiency and test accuracy of the ear vagus nerve stimulator; 3. It can detect multiple products at the same time, quickly screen out unqualified products, and control the multi-mode switching of products, read the product serial number and store test data.

[0033] The following is an explanation of the use of the test device.

[0034] When preparing for testing, the first step is to install the hexagonal nut into the nut installation slot of the upper shell, then put the circuit board into the circuit board storage slot of the upper shell, assemble the lower shell, and lock the upper shell and the lower shell with 4 pairs of screws and nuts to fix the circuit board.

[0035] The second step is to install the conductive ring into the mounting hole of the lower shell, weld the wire, connect one end of the wire to the conductive ring, and the other end to the output end of the earplug electrode of the circuit board, place the conductive ring in the boss of the lower shell, align one end of the round base of the conductive ring fixing with the conductive ring and place it in the square hole of the lower shell, press and fix it, and use a pair of screws and nuts to limit and lock the conductive ring fixing.

[0036] In the third step, the assembled test fixture is connected to the female connector of the test board through the male connector. Multiple test fixtures can be connected according to the number of tests required.

[0037] The fourth step is to turn on the ear vagus nerve stimulator, insert the earplug electrode of the ear vagus nerve stimulator into the conductive ring, make the auricle electrode contact and connect with the circular conductive area of ​​the circuit board, and perform the circuit board conductive loop detection. The ear vagus host is connected to the test fixture through the female connector and the male connector of the test fixture, and placed in the test fixture storage slot.

[0038] The fifth step is to turn on the switch of the test fixture. The serial number information of the product is sent to the monitoring module of the control terminal through the test fixture. After receiving the serial number information, the monitoring module stores and displays the data, and controls the indicator light of the test fixture through the display module to display green, indicating that the connection is successful.

[0039] Step 6. After the connection is successful, the host is automatically triggered to start running. The host feeds back the stimulation signal output by the stimulation electrode to the signal receiving module of the control terminal, stores it after data analysis and judgment, and then automatically switches the mode of the host on the test fixture through the mode switching module. Similarly, the data in different modes are tested and stored in a cycle. If the test process data is unqualified, it will be fed back to the indicator light of the test fixture through the display module. Flashing red light indicates that the product is unqualified.

[0040] Step 7. After the batch test is completed, all test data can be exported to facilitate data analysis and traceability management of the corresponding products.
