DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] As shown in Figure 1 , Figure 4 , Figure 6 , the present application provides a medical EEG headgear with a protection structure, comprising a wearing ring 1, further comprising:

[0049] a limiting ring 2 arranged on the inner side of the wearing ring 1;

[0050] The annular plate 3 is sleeved on the limiting ring 2 and is arranged in parallel with the central axis of the wearing ring 1.

[0051] The first elastic member 4 is arranged between the annular plate 3 and the limiting ring 2.

[0052] The displacement rod 5 is arranged in the annular plate 3 and is arranged in perpendicular to the central axis of the wearing ring 1.

[0053] The second elastic member 6 is arranged between the displacement rod 5 and the annular plate 3.

[0054] The flexible detection sheet 7 is arranged at the end of the displacement rod 5 and the other end is arranged adjacent to the central axis of the wearing ring 1.

[0055] When the flexible detection sheet 7 contacts the head of the person to be detected, the flexible detection sheet 7 is driven to displace away from the central axis of the wearing ring 1 and the annular plate 3 and the flexible detection sheet 7 are vertically displaced to adapt to the detection points of the head of the person to be detected in the horizontal direction and the vertical direction respectively.

[0056] Through the design of the horizontal and vertical displacement of the flexible detection sheet 7 and the annular plate 3, the surface undulations of different head shapes can be adapted, the range of applicable people is expanded, the accurate fitting of the detection sheet and the detection point is ensured, the detection error caused by position deviation is reduced, and the accuracy of the detection signal is protected.

[0057] For example, for the case that there is a special detection point on the temple of the head, the flexible detection sheet 7 can displace horizontally to the temple, vertically displace to the same height as the detection point, ensure the accurate alignment of the flexible detection sheet 7 with the detection point, effectively protect the accuracy of the detection point, and improve the reliability of the detection result.

[0058] As shown in Figure 1 , Figure 5 , further comprising:

[0059] The sliding block 8 is arranged on the annular plate 3.

[0060] One end of the displacement rod 5 penetrates the sliding block 8, and the other end is connected with the flexible detection sheet 7.

[0061] The above design can make the flexible detection sheet 7 displace circumferentially under the cooperation of the sliding block 8, so as to adapt to different detection points of different people's heads at multiple angles. The detection points of different regions of the head are widely and irregularly distributed, and this displacement adaptation mechanism can cover more potential detection points. During the detection process, even if there are some detection points that are not easy to detect or are relatively hidden in position, through the flexible displacement in the horizontal, vertical and circumferential directions, the omission of the detection points is prevented, and the integrity of the detection process is protected.

[0062] The second elastic member 6 is arranged between the sliding block 8 and the flexible detection sheet 7.

[0063] The elastic characteristic of the second elastic member 6 enables the flexible detection sheet 7 to automatically adjust to a state of being in contact with the scalp according to the shape and hardness of the scalp.

[0064] As shown in Figure 3 , Figure 4 , the arc-shaped abutting plate 9 is further provided, which is connected to the end of the flexible detection sheet 7, and a soft pad is arranged on the side of the arc-shaped abutting plate 9 away from the wearing ring 1, so that a good comfort can be provided when the arc-shaped abutting plate 9 contacts the head of the person to be detected.

[0065] The arc-shaped design of the arc-shaped abutting plate 9 can be pushed to move when contacting the human head, so that the movement of the flexible detection sheet 7 can be smoothly realized without additional operation, and compared with directly contacting the human head with the flexible detection sheet 7, the local pressure concentration can be reduced, and the wearing comfort can be improved.

[0066] The end of the arc-shaped abutting plate 9 away from the flexible detection sheet 7 extends to the outside of the wearing ring 1 as an operation end 10.

[0067] The operation end 10 is located outside the wearing ring 1, so that the operator can intuitively and conveniently adjust without directly contacting the flexible detection sheet 7 or other internal sensitive components, so that damage to the detection components caused by misoperation can be avoided, and direct contact between the operator and the detection area can be reduced.

[0068] The above design enables the flexible detection sheet 7 to slide on the plane of the annular plate 3 in addition to the original horizontal and vertical displacement, so that when the head detection point positions of the person to be detected are irregularly distributed, the operator can control the sliding of the sliding block 8 through the operation end 10 or the flexible detection sheet 7, so that the flexible detection sheet 7 can be more accurately aligned with the detection point positions, and the detection accuracy and flexibility can be further improved.

[0069] As shown in Figure 4 , Figure 7 , the annular plate 3 comprises:

[0070] A plurality of butt joint rings 31 are provided, each of which has a containing cavity 32, the limiting ring 2 abuts one end of the containing cavity 32, and the first elastic member 4 is arranged between the limiting ring 2 and the other end of the containing cavity 32;

[0071] The first elastic member 4 arranged in each butt joint ring 31 can enable the corresponding flexible detection sheet 7 to independently adjust the vertical position according to the specific conditions of the head at the position, for example, for the case that one side of the head is relatively flat and the other side has a significant curvature, the corresponding flexible detection sheet 7 can adjust the vertical height to fit the head contour through the first elastic member 4 in the respective butt joint ring 31, so that the detection head 72 can be in good contact with the head detection point positions, and the detection accuracy can be improved.

[0072] The assembly area 33 is between the adjacent abutting rings 31;

[0073] The length of the slider 8 in the sliding direction is greater than the distance of the assembly area 33 between the adjacent abutting rings 31;

[0074] This design can effectively prevent the slider 8 from falling off from the assembly area 33 during sliding, ensuring the stability of the slider 8 sliding on the ring plate 3, and further ensuring the normal work of the displacement rod 5 and the flexible detection sheet 7;

[0075] The assembly area 33 is provided with a fixing block 34, and the limiting ring 2 and the wearing ring 1 are fixedly connected through the fixing block 34.

[0076] As shown in Figure 6 , Figure 7 , the first elastic member 4 is a snake-shaped spring, and the second elastic member 6 is a spiral spring;

[0077] The snake-shaped spring and the spiral spring can be respectively adapted to the installation space of the accommodating cavity 32 and the displacement rod 5 for use.

[0078] As shown in Figure 2 , Figure 5 , the flexible detection sheet 7 comprises:

[0079] A flexible assembly sheet 71 slides along the circumference on the abutting ring 31 along with the slider 8;

[0080] A plurality of detection heads 72 are arranged to slide along the radial direction of the flexible assembly sheet 71;

[0081] The electrode collection end of the detection head 72 has a plurality of strip-shaped silica gel protections, which can be inserted into the hair and scalp contact and fit during the insertion process, similar to the combing of hair, to reduce the interference of hair on the detection signal, ensure the direct contact of the electrode collection end with the scalp, and improve the reliability of the detection result;

[0082] The flexible assembly sheet 71 and the detection head 72 respectively slide along the circumference and the radial direction to adapt to the detection point of the head of the person to be detected.

[0083] The sliding of the flexible assembly sheet 71 along the circumference and the sliding of the detection head 72 along the radial direction can cooperate with each other to meet the requirements of various complex shapes of the head of the person to be detected (whether the head is wide or narrow, round or oval) and the detection point (the surface of the scalp is uneven, irregular shape, such as the different radii and slopes of the forehead, temporal part, etc.), improve the applicability to different individuals, realize positioning and fitting, protect the effective collection of the detection point signal, and improve the quality of the detection result.

[0084] As shown in Figure 3 , Figure 8As shown in the drawings, the flexible assembly piece 71 is provided with a slide 11 in the radial direction, and the flexible assembly piece 71 is provided with a guide channel 12 which is in communication with the slide 11, and the guide channel 12 is slidably provided with a limiting shell 13, and the limiting shell 13 is provided with a detection head 72 which is slidably arranged in the slide 11.

[0085] The slide 11 and the guide channel 12 provide a stable guide path for the radial sliding of the detection head 72, so that the detection head 72 is not easy to deviate during the sliding process, and the stability of the adjustment process is ensured.

[0086] As shown in the drawings, Figure 8 , Figure 9 The limiting shell 13 is provided with an internal threaded hole 14, the detection head 72 is rotatably provided with a threaded column 15 which is connected with the internal threaded hole 14, and the outer side of the threaded column 15 is provided with a positioning piece 16 which abuts against the flexible assembly piece 71.

[0087] The internal threaded hole 14 in the limiting shell 13 cooperates with the threaded column 15 on the detection head 72 to adjust the extension length of the detection head 72 in the slide 11, and for different scalp contour conditions, the detection head 72 can be flexibly changed to fit the scalp.

[0088] The positioning piece 16 comprises a positioning link 161 which is rotatably arranged on the outer side of the threaded column 15, a return spring 162 is arranged between the positioning link 161 and the limiting shell 13, an end portion of the threaded column 15 is provided with a control block 163, the control block 163 is rotatably provided with an abutting column 164 on the side facing the positioning link 161, and the flexible assembly piece 71 is provided with a plurality of link grooves 165 at equal intervals.

[0089] During the detection head 72 is inserted, the abutting column 164 pushes the positioning link 161 to be clamped with the link groove 165, so as to fix the detection head 72 at different radial positions, and the cooperation of the self-locking thread can realize the fixing operation of the detection head position, and the positioning link 161 can be automatically reset after being separated from the link groove 165 through the return spring 162, so as to provide convenience for the next positioning.

[0090] The working principle and use process of the present application are as follows:

[0091] When wearing the device, the wearing ring 1 is sleeved on the head, and because the head diameters of different people are different, the arc-shaped abutting plate 9 first contacts the head of the person to be detected, and pushes the arc-shaped abutting plate 9 and the displacement rod 5 to produce transverse displacement to compress the second elastic member 6, the flexible detection piece 7 follows the movement to adapt to the transverse difference of the head of the person to be detected, and the plurality of annular plates 3 can also produce vertical displacement under the action of the first elastic member 4 to adapt to the longitudinal difference of the head of the person to be detected, that is, the preliminary wearing operation is completed.

[0092] According to the distribution of the detection points, the flexible assembly piece 71, the sliding block 8 and the arc-shaped abutting plate 9 can be driven by the operation end 10 to slide along the circumference to be in the same plane with the head detection point, and then the detection head 72 is moved along the radial direction in the sliding channel 11 to be close to the detection point, so as to complete the alignment operation of the detection point.

[0093] Then, the annular plate 3 is driven by the operation end 10 to be displaced under the action of the first elastic member 4, so that the detection head 72 on the flexible assembly piece 71 is closer to the detection point, and the detection head 72 is rotated to be close to the head detection point under the rotation of the threaded column 15 in the internal threaded hole 14, at the same time, the abutting column 164 pushes the positioning link block 161 to be close to the link groove 165 to be clamped, the reset spring 162 is compressed, the position of the detection head 72 is fixed, the detection head is attached to the detection point, and the whole detection positioning operation is completed.
