Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a scalp pressure detection device for a cochlear implant sound processor. Background Technology

[0002] The cochlear implant system consists of an implant and a sound processor. The implant is placed in the patient's head, while the sound processor is worn on the outside of the head. Both are secured and transmit data using magnetic force. To ensure patient safety and comfort, national regulations require that the magnetic pressure on the scalp be controlled within a certain range. Therefore, pressure testing is necessary before the product leaves the factory. Currently, pressure testing typically uses a metal fixture for positioning and clamping, with a 2mm thick pad for testing. This fixture is complex to install, easily scratching the product surface and causing aesthetic defects; it also requires skilled operators and has low testing efficiency. Therefore, a novel scalp pressure testing device for cochlear implant sound processors needs to be designed to avoid damage to the product during testing, simplify the device structure, and improve testing efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a scalp pressure detection device for cochlear implant sound processors. This device can simplify the structure and improve detection efficiency while avoiding damage to the product during detection.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] This utility model provides a scalp pressure detection device for a cochlear implant sound processor, including a sound processor positioning plate, an implant fixation plate, and a pressure detection component;

[0006] The implant fixing plate has a groove that matches the shape of the implant for placing the implant; the sound processor positioning plate is placed above the implant fixing plate, and the sound processor positioning plate has a cavity that matches the shape of the sound processor to be tested for securing the sound processor. The side of the cavity that contacts the sound processor is covered with a cushioning material, and a pad for simulating the human scalp is provided between the cavity and the implant fixing plate.

[0007] The pressure detection component includes a lifting device and a tension indicator. One end of the lifting device is connected to the tension indicator, and the other end is connected to the sound processor positioning plate. The sound processor positioning plate and the implant fixation plate are connected by magnetic attraction between the sound processor and the implant. The lifting device is used to apply a tension force away from the implant fixation plate to the sound processor positioning plate. The tension indicator is used to read the value of the tension force applied by the lifting device when the sound processor positioning plate is completely separated from the implant fixation plate, which is used as the scalp pressure detection result of the cochlear implant sound processor.

[0008] Furthermore, the buffer material is a PK material.

[0009] Furthermore, the thickness of the pad is 2mm.

[0010] Furthermore, the implant is placed into the groove of the implant fixation plate and then secured with adhesive tape.

[0011] Furthermore, the lifting device is connected to the tension indicator via a lifting ring.

[0012] Furthermore, the lifting device includes multiple connecting rods of equal length and multiple hanging ropes of equal length. Each connecting rod is set perpendicular to the sound processor positioning plate, with one end fixed to the side of the sound processor positioning plate away from the implant fixation plate, and the other end connected to the lifting ring via a hanging rope.

[0013] Furthermore, the center of mass of the area enclosed by all the connecting rods of the sound processor positioning plate coincides with the center of mass of the entire sound processor positioning plate.

[0014] Furthermore, the number of connecting rods is 4.

[0015] Furthermore, the surface of the implant fixation plate is provided with a limiting mark. After the sound processor positioning plate is placed based on the limiting mark, the sound processor on the sound processor positioning plate and the implant on the implant fixation plate are directly opposite each other.

[0016] Furthermore, the limiting mark is a vertical protrusion that matches the edge of the sound processor positioning plate.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This utility model designs a scalp pressure detection device for a cochlear implant sound processor, including a sound processor positioning plate, an implant fixation plate, and a pressure detection assembly. The implant fixation plate has a groove matching the shape of the implant for placement. The sound processor positioning plate is placed above the implant fixation plate and has a cavity matching the shape of the sound processor to be tested, allowing direct insertion and fixation of the sound processor. The side of the cavity in contact with the sound processor is covered with cushioning material to prevent scratching the product surface during testing. A pad simulating the human scalp is provided between the cavity and the implant fixation plate to press... The force detection component includes a lifting device and a tension indicator. One end of the lifting device is connected to the tension indicator, and the other end is connected to the sound processor positioning plate. The sound processor positioning plate and the implant fixation plate are magnetically attracted to each other by the sound processor and the implant. The lifting device applies a tension force away from the implant fixation plate to the sound processor positioning plate. When the sound processor positioning plate is completely separated from the implant fixation plate, the value read by the tension indicator is the scalp pressure detection result of the cochlear implant sound processor. The above device eliminates the need to place a pad simulating the human scalp during each test, and also eliminates the need to adjust the clamping device to fix the sound processor before each test, thus improving the testing efficiency to a certain extent.

[0019] 2. In this utility model, the lifting device and the tension indicator are connected by a lifting ring. The lifting device includes multiple connecting rods of equal length and multiple lifting ropes of equal length. Each connecting rod is set perpendicular to the sound processor positioning plate. One end of the connecting rod is fixed to the side of the sound processor positioning plate away from the implant fixation plate, and the other end is connected to the lifting ring by a lifting rope. The center of mass of the area of ​​the sound processor positioning plate surrounded by all the connecting rods coincides with the center of mass of the entire sound processor positioning plate. This can avoid uneven force distribution among the connecting rods, which would affect the resultant force of each connecting rod and thus cause errors in the final test result. This can maintain the stability of the test process and improve the reliability of the test result. Attached Figure Description

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] Example:

[0028] This embodiment provides a scalp pressure detection device for a cochlear implant sound processor, such as... Figure 1 As shown, it includes a sound processor positioning plate 5, an implant fixation plate 8, and a pressure detection component.

[0029] like Figure 3 As shown, the implant fixation plate 8 has a groove matching the shape of the implant 7 for placing the implant 7. The sound processor positioning plate 5 is placed above the implant fixation plate 8. The sound processor positioning plate 5 has a cavity matching the shape of the sound processor 6 to be tested for securing the sound processor 6, avoiding the need to adjust the clamping device to fix the sound processor before each test, thus improving testing efficiency to some extent. The side of the cavity that contacts the sound processor 6 is covered with a cushioning material (e.g., PK material) to prevent scratching the product surface during testing. Figure 2 As shown, a pad (generally 2mm thick) for simulating human scalp is provided between the cavity and the implant fixation plate 8, so that the pad for simulating human scalp does not need to be placed during each test.

[0030] The pressure detection component includes a lifting device and a tension indicator 1. One end of the lifting device is connected to the tension indicator 1, and the other end is connected to the sound processor positioning plate 5. Because there is a magnetic force between the sound processor 6 and the implant 7, the sound processor positioning plate 5 is initially attracted to the implant fixation plate 8. A pulling force is applied to the sound processor positioning plate 5 away from the implant fixation plate 8 using the lifting device. When the sound processor positioning plate 5 is completely separated from the implant fixation plate 8, the value read by the tension indicator 1 is the scalp pressure detection result of the cochlear implant sound processor.

[0031] In a preferred embodiment, such as Figure 1 As shown, the lifting device can be configured as follows: The lifting device includes four connecting rods 4 of equal length and four hanging ropes 3 of equal length. Each connecting rod 4 is perpendicular to the sound processor positioning plate 5, with one end fixed to the side of the sound processor positioning plate 5 away from the implant fixation plate 8, and the other end connected to the hanging ring 2 via a hanging rope 3. The lifting device is also connected to the tension indicator 1 via the hanging ring 2. To maintain the stability of the testing process, the center of mass of the area enclosed by all the connecting rods 4 of the sound processor positioning plate 5 coincides with the center of mass of the entire sound processor positioning plate 5. This avoids uneven force distribution among the rods, which would affect the resultant force of each rod and improve the reliability of the testing results.

[0032] In another preferred embodiment, the surface of the implant fixation plate 8 is provided with limiting marks (e.g., vertical protrusions that match the four corners of the sound processor positioning plate 5). After the sound processor positioning plate 5 is placed based on the limiting marks, the sound processor 6 located on the sound processor positioning plate 5 and the implant 7 located on the implant fixation plate 8 are directly opposite each other, which can reduce the error of the detection results.

[0033] The specific steps for using the above device are as follows:

[0034] S1. Fix the implant fixation plate 8 on the horizontal platform.

[0035] S2. Place the implant 7 into the groove on the implant fixation plate 8, and then fix it with tape.

[0036] S3. Press the sound processor 6 into the cavity of the sound processor positioning plate 5, and place the sound processor positioning plate 5 on the implant fixation plate 8.

[0037] S4. Pull the lifting device vertically upwards until the sound processor positioning plate 5 is completely separated from the implant fixation plate 8, and read the value of the tension indicator 1 at this time as the test result.

[0038] In a preferred embodiment, the lifting device can be controlled by a motor to make the applied force more uniform, thereby further improving the accuracy of the test results and the ease of operation.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
