Description

Technical Field

[0001] This application relates to the field of bioelectronics technology, and in particular to a brain oxygenation detection cap. Background Technology

[0002] Cerebral oxygenation detection technology is an important tool in modern medicine for monitoring the oxygenation status of the brain, especially in neurosurgery, neurological monitoring, and intensive care, where brain oxygen saturation can provide crucial information for clinical decision-making. Currently, most common cerebral oxygenation detection devices use optical principles, analyzing the oxygenation level in the blood under the scalp through light signals emitted by a light source and light signals received by a detector.

[0003] Existing brain oxygenation detection devices typically mount the detection head directly onto the cap body. The detection head includes a light source and a detector. The light source emits light of a specific wavelength, and the detector receives the light signals reflected or scattered by the scalp and tissues. The mounting base is generally fixed directly into the through-hole of the cap body using a simple fixing structure, such as a snap-fit ​​or thread.

[0004] However, existing brain oxygenation detection devices fix the mounting base directly inside the through hole of the cap. This direct mounting method makes it difficult to ensure that the light source and detector are always perpendicular to the scalp. During use, the tilt of the light source and detector will affect the transmission path of the light signal, resulting in errors in the detection results and affecting the accuracy of the brain oxygenation signal. Utility Model Content

[0005] To ensure that the light source and detector remain perpendicular to the scalp to a certain extent, thus minimizing errors in the detection results, this application provides a brain oxygenation detection cap. This application provides the following technical solution:

[0006] A brain oxygenation detection cap includes a cap body with a through hole. A detection head mounting seat is snapped into the through hole. The detection head mounting seat includes a connecting plug and a mounting part. The plug passes through the through hole, and the mounting part is used to connect with a light source or detector used in conjunction with the brain oxygenation detection cap. The portion between the plug and the mounting part is located in the through hole and is snapped with a gasket.

[0007] In one specific implementation, the detection head mounting base has an annular groove located between the insertion part and the mounting part, and the detection head mounting base is engaged with the through hole of the cap body through the annular groove.

[0008] In one specific implementation, the gasket includes a sheet body, with a mating portion at one end of the sheet body near the detection head mounting base and a snap-fit ​​portion at the other end of the sheet body away from the detection head mounting base. The sheet body, the mating portion, and the snap-fit ​​portion are engaged in the annular groove and located below the cap body.

[0009] In one specific implementation, an annular protrusion is provided between the snap-fit ​​portion and the plate body, and the diameter of the annular protrusion is smaller than the diameter of the mounting portion and the plug-in portion.

[0010] In one specific implementation, the annular protrusion is provided with a chamfer.

[0011] In one specific implementation, the mounting part is provided with internal threads, and the light source or detector is connected to the mounting part via the threads.

[0012] In one specific implementation scheme, there are multiple through holes, detection head mounting bases, and gaskets, and the through holes, detection head mounting bases, and gaskets are in one-to-one correspondence.

[0013] In summary, the beneficial effects of this application include at least the following:

[0014] 1) Because the diameter of the annular protrusion is smaller than the diameter of the insertion part and the mounting part, the gasket is not easy to fall off in the annular groove, thereby avoiding the loosening or rotation of the detection head and ensuring that the light source and detector are always kept in the correct working position, especially perpendicular to the scalp.

[0015] 2) The threaded connection not only provides reliable mechanical fixation, but also makes the installation and replacement of light sources or detectors more convenient. It supports modular design, and users can replace different detectors or light sources as needed.

[0016] By simultaneously securing the cap and gasket within the annular groove, the overall robustness of the device is ensured. This design utilizes the extensibility of the cap and the limiting effect of the annular groove to prevent the device from easily loosening or shifting during use, thus guaranteeing a stable working state of the detection head. To a certain extent, this also ensures that the light source and detector remain perpendicular to the scalp during operation, thereby improving detection accuracy.

[0026] This application discloses a brain oxygenation detection cap.

[0027] Reference Figure 1The cerebral oximetry cap includes a cap body 1 with several through holes 11. Taking one through hole 11 as an example, a detailed description is provided below. Each through hole 11 houses a detection head mounting seat 2. The detection head mounting seat 2 includes a fixedly connected insertion part 22 and a mounting part 23. An annular groove 21 is also provided on the detection head mounting seat 2, located between the insertion part 22 and the mounting part 23. The detection head mounting seat 2 is engaged within the through hole 11 of the cap body 1 via the annular groove 21, thus completing the engagement. (Combined with...) Figure 2 The mounting part 23 is used to connect to a light source or detector used in conjunction with a cerebral oxygenation detection cap. The mounting part 23 has an internal thread 25, through which the light source or detector connects to the mounting part 23. The internal thread 25 on the mounting part 23 facilitates the installation of the light source or detector. This threaded connection not only provides reliable mechanical fixation but also makes the installation and replacement of the light source or detector more convenient, supporting a modular design, allowing users to replace different detectors or light sources as needed.

[0028] Reference Figure 1 and Figure 3 After the detection head mounting base 2 is engaged with the through hole 11, a gasket 3 is engaged with the detection head mounting base 2 through the through hole 11. The gasket 3 includes a sheet body 32, with a mating portion 31 at the end of the sheet body 32 near the insertion portion 22 and a engaging portion 33 at the end of the sheet body 32 away from the insertion portion 22. An annular protrusion 34 is provided between the engaging portion 33 and the sheet body 32. The annular protrusion 34 is made of flexible material and has a chamfer. In practice, after the detection head mounting base 2 is engaged with the through hole 11, the gasket 3 is also engaged in the annular groove 21 located between the insertion portion 22 and the mounting portion 23. At this time, the sheet body 32, the engaging portion 33, and the mating portion 31 are all engaged in the through hole 11 and located below the cap body 1. At the same time, the annular protrusion 34 can play a certain limiting role. The diameter of the annular protrusion 34 is smaller than the diameter of the mounting portion 23 and the insertion portion 22, making it difficult for the gasket 3 to fall out of the annular groove 21. The annular protrusion 34 is made of flexible material, which can adapt to a certain range of displacement and deformation, providing a good buffering effect and preventing the connecting parts from being too tight or too loose due to external forces, thus improving the stability and service life of the overall structure. The annular protrusion 34, made of flexible material, is inserted into the annular groove 21, providing additional limiting function. Because the diameter of the annular protrusion 34 is smaller than the diameter of the insertion part 22 and the mounting part 23, the gasket 3 is not easily dislodged within the annular groove 21, thereby preventing the detection head from loosening or rotating, ensuring that the light source and detector always remain in the correct working position, especially perpendicular to the scalp. Several through holes 11, detection head mounting base 2, and gaskets 3 are provided, and each through hole 11, detection head mounting base 2, and gasket 3 corresponds to another gasket 3.

[0029] In summary, the cerebral oximetry cap consists of a cap body 1, several through holes 11, a detection head mounting base 2, and a gasket 3. The cap body 1 has multiple through holes 11, each of which houses the detection head mounting base 2. The detection head mounting base 2 consists of a connector 22 and a mounting part 23, and has an annular groove 21. The mounting part 23 has internal threads 25 for connection to a light source or detector, supporting a modular design that allows users to easily replace the detector or light source as needed. By simultaneously fixing the cap body 1 and the gasket 3 within the annular groove 21, the overall stability of the device is ensured. This design utilizes the extensibility of the cap body 1 and the limiting effect of the annular groove 21, making the device less prone to loosening or displacement during use, thus ensuring a stable working state of the detection head. To a certain extent, it ensures that the light source and detector remain perpendicular to the scalp during operation, thereby improving the accuracy of the detection.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
