Description

Technical Field

[0001] This utility model relates to the field of electroencephalogram (EEG) signal acquisition technology, specifically to a sensor fixing device for headwear. Background Technology

[0002] Commonly known physiological sensors typically connect to metal clips via lead wires, which in turn connect to electrode pads via snap-fit ​​connections. Standard EEG lead wires consist of three leads: positive, negative, and reference. GSR (Georetinal Surgical Resonance) leads have two wires, while TEMP (Temperature Modulation) leads consist of 2-4 wires depending on the probe. Before treatment, the sensor probes and electrode pads need to be installed, and the electrode pads must be individually attached to the skin. When treating a large number of patients, this preparation process is time-consuming, increasing the operator's workload and resulting in low efficiency.

[0003] To address the problems existing in the prior art, utility model CN222384054U discloses a headband-mounted transcranial magnetic stimulation device (hereinafter referred to as Prior Art 1), comprising a ring-shaped headband, a fixing rod inside the ring-shaped headband, several electromagnetic blocks distributed and installed on the fixing rod, an EEG detection module, a composite detection module, and a main control box installed on the fixing rod, the composite detection module including a body temperature detection module, a blood oxygen detection module, and a heart rate detection module, the composite detection module being installed on the fixing rod at the temple position, the main control box containing a communication module, a controller, a battery, and a pulse circuit adjustment module, the blood oxygen detection module, the communication module, and the pulse circuit adjustment module being electrically connected to the controller, the electromagnetic blocks being electrically connected to the pulse circuit adjustment module, the communication module being used to transmit detection data to a host computer and receive instructions from the host computer, the electromagnetic blocks adjusting the transmission power according to the controller instructions, and the battery supplying power to the power modules within the device.

[0004] In the prior art 1, by mounting each detection module on a ring headband, all sensors can be worn by wearing the ring headband. However, during the detection process, the fixation effect of wearing each detection module by the ring headband alone is not good. If the user moves slightly during the detection process (such as nodding or turning their head), the electrodes of a single headband may shift or loosen due to the single direction of force.

[0034] Example

[0035] See Figures 1-3 This embodiment discloses a fixing device for fixing a sensor detection module to the head of a person being tested. Specifically, it is a sensor fixing device for headwear, including a data acquisition module 101 and a ring fixing component 102. The data acquisition module 101 is mounted on the ring fixing component 102.

[0036] The ring-shaped fixing assembly 102 includes a fixing plate 103 and a first fixing strap 104. The left and right ends of the fixing plate 103 are connected by the first fixing strap 104. A second fixing strap 105 is installed on the first fixing strap 104. The first fixing strap 104 and the second fixing strap 105 are connected to form an installation area for fitting onto the patient's head.

[0037] A rotating part 106 is symmetrically and rotatably mounted on the first fixing strap 104, and the left and right ends of the second fixing strap 105 are connected to the first fixing strap 104 through the rotating part 106.

[0038] In this embodiment, the acquisition module 101 is used to detect the subject's brain electrical activity, sweating rate, and skin temperature. By mounting the acquisition module 101 on the ring fixation component 102, the subject can complete the setting of multiple sensors after wearing the ring fixation component 102, making the electrodes reusable and simplifying the installation process. After the first fixation strap 104 and the second fixation strap 105 are connected, a hemispherical installation area for fitting onto the patient's head is formed between the first fixation strap 104, the second fixation strap 105, and the fixation plate 103, allowing the first fixation strap 104 and the second fixation strap 105 to... The second fixing strap 105 better conforms to the contour of the subject's head, preventing the fixing plate 103 and the acquisition module 101 from shifting or loosening during slight user movements, thus ensuring the stability, safety, and accuracy of the acquisition module 101 during use. After the left and right ends of the second fixing strap 105 are rotatably connected to the first fixing strap 104 through the rotating part 106, the subject can rotate the second fixing strap 105 according to the size and shape of their head to fine-tune the position of the second fixing strap 105, ensuring that the second fixing strap 105 fits tightly to the subject's head without causing pressure, thus improving the subject's user experience.

[0039] In some embodiments, the second fixation strap 105 is an elastic band structure. By making the second fixation strap 105 an elastic band structure, the test subject can adjust the length of the second fixation strap 105 according to the size and shape of their head, and under the elastic force provided by the elastic band structure, the second fixation strap 105 can further conform to the patient's head.

[0040] In some embodiments, the rotating part 106 is provided with an opening, and an adjusting shaft 108 is installed in the opening. One end of the second fixing strap 105 located inside the rotating part 106 is fixedly connected to the adjusting shaft 108. A limiting mechanism 109 for limiting the adjusting shaft 108 is provided inside the rotating part 106. In this embodiment, the adjusting shaft 108 is movably connected to the opening, and the second fixing strap 105 is slidably connected to the rotating part 106. By rotating the adjusting shaft 108, the second fixing strap 105 can be wound around the adjusting shaft 108 or unwound and moved outside the rotating part 106. The subject can adjust the length of the second fixing strap 105 according to the size and shape of their head. After the length of the second fixing strap 105 is adjusted to a suitable size, the limiting mechanism 109 can lock the adjusting shaft 108, so that the length of the second fixing strap 105 no longer changes, further improving the stability and accuracy of the acquisition module 101 during use.

[0041] In some embodiments, the limiting mechanism 109 includes a limiting block 113 and a spring 111. The spring 111 is rotatably mounted in the rotating part 106, and the adjusting shaft 108 is rotatably connected to the rotating part 106 through the spring 111. The connecting block 110 is fixedly mounted in the rotating part 106, and a limiting groove 112 is provided on the connecting block 110. A limiting block 113 that cooperates with the limiting groove 112 is fixedly connected to the adjusting shaft 108. In this embodiment, a rotating rod is rotatably mounted on the rotating part 106, and the end of the spring 111 away from the adjusting shaft 108 is fixedly connected to the rotating rod; there are several limiting grooves 112, which are evenly spaced along the circumferential direction of the connecting block 110; when it is necessary to rotate the adjusting shaft 108 to adjust the length of the second fixing belt 105, the adjusting shaft 108 is pushed towards the spring 111 to compress the spring 111. After the adjusting shaft 108 moves until the limiting block 113 separates from the limiting groove 112, the adjusting shaft 108 can be rotated to... The second fixing band 105 is wound around the adjusting shaft 108 or unwound and moved outside the rotating part 106 to adjust the length of the second fixing band 105. After the length of the second fixing band 105 is adjusted to a suitable size, the limiting block 113 moves into the limiting groove 112 under the action of the elastic force provided by the compressed spring 111. The limiting block 113 and the limiting groove 112 can lock the adjusting shaft 108, so that the length of the second fixing band 105 no longer changes, further improving the stability and accuracy of the acquisition module 101 in use.

[0042] In some embodiments, there are two first fixing straps 104, which are respectively connected to the left and right ends of the fixing plate 103. Adjustable buckles 115 are provided on each first fixing strap 104 for connecting the two straps. In this embodiment, the adjustable buckle 115 is a conventional connecting buckle in the prior art. The adjustable buckle 115 is installed on either first fixing strap 104, allowing the two first fixing straps 104 to be connected and their length adjusted. This allows the user to adjust the length of the two connected first fixing straps 104 according to the size and shape of their head.

[0043] In some embodiments, the fixing plate 103 has an arc-shaped structure. In this embodiment, by setting the fixing plate 103 to an arc shape, the acquisition module 101 installed on the concave surface of the fixing plate 103 can fit closely to the head of the subject, improving the accuracy and stability of signal acquisition while reducing discomfort during wear.

[0044] In some embodiments, a buffer pad 107 is installed on the second fixing strap 105. The buffer pad 107 is made of rubber or sponge material. By setting the buffer pad 107, the contact area between the second fixing strap 105 and the head of the subject can be increased, thereby improving the stability of the acquisition module 101 during the detection process. Furthermore, by setting the buffer pad 107, the pressure exerted by the second fixing strap 105 on the head of the subject under the weight of the fixing plate 103 and the acquisition module 101 can be dispersed, preventing the subject's head from feeling pain or discomfort during the detection process.

[0045] In some embodiments, the acquisition module 101 includes an electroencephalogram (EEG) sensor, a skin conductance sensor, and a skin temperature sensor mounted on the fixing plate 103. In this embodiment, the EEG sensor, skin conductance sensor, and skin temperature sensor are conventional sensors used in the prior art to detect brain electrical activity, sweating rate, and skin temperature, and their specific structures and functions will not be described in detail here.

[0046] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
