Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an adjustable elastic cap for electroencephalography (EEG). Background Technology

[0002] Video electroencephalography (VEEG) combines an electroencephalogram (EEG) monitoring system with a recording device to synchronously and dynamically record the patient's EEG and the child's consciousness and activity levels. This helps doctors interpret the clinical significance of EEG changes in conjunction with the child's abnormal behavior in the context of the situation, thereby achieving accurate diagnosis. In pediatric intensive care, VEEG is not only a core tool for assessing brain function but also a key technology for achieving precise neurocritical care, especially in critical scenarios such as coma, status epilepticus, and brain injury, where VEEG can provide real-time, dynamic information on brain function.

[0003] The entire process of performing a video EEG requires wearing a matching EEG fixation cap. The existing EEG fixation caps have a fixed size. Due to the differences in head circumference and compliance among children of different ages, the cap may become too large and cause the electrodes to loosen, or too small and cause pressure injuries to the child's head.

[0004] Therefore, designing a fixed cap that can be adjusted in size according to the size of the child's head has become an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable elastic EEG cap, which can solve the problems of existing EEG caps having a fixed size, where too large a cap will cause the electrodes to fall off, and too small a cap will cause pressure sores on the scalp.

[0006] To achieve the above objectives, this utility model provides an adjustable elastic cap for EEG, the specific implementation of which is as follows:

[0007] An adjustable elastic cap for EEG includes a loop-shaped latitudinal elastic band for placement along the latitudinal direction of the head and a semi-loop-shaped radial elastic band for placement along the radial direction of the head. The two ends of the latitudinal elastic band are connected by Velcro with adjustable fastening. The two ends of the radial elastic band are connected to the latitudinal elastic band, and at least one end of the radial elastic band passes around the latitudinal elastic band and is then connected to the radial elastic band itself by Velcro with adjustable fastening. The radial elastic band is divided into a first radial elastic band placed on the head along a first radial direction and a second radial elastic band placed on the head along a second radial direction. The first radial direction is perpendicular to the second radial direction, and the first radial direction is a radial direction from the forehead to the back of the head.

[0008] In one embodiment, the weft elastic band includes a weft band body and an inner hook and loop fastener layer disposed at one end of the weft band body. The weft band body includes a skin-friendly layer, an elastic layer and an outer hook and loop fastener layer disposed sequentially from the inside to the outside. The inner hook and loop fastener layer is located on the side of the skin-friendly layer that faces away from the elastic layer.

[0009] In one embodiment, the number of the second radial elastic bands is three, and the three second radial elastic bands are arranged at intervals along the first radial direction.

[0010] In one embodiment, the first radial elastic band has a front end near the child's forehead and a rear end near the back of the child's head; the front end of the first radial elastic band passes around the latitudinal elastic band and is connected to the first radial elastic band itself by means of Velcro with adjustable position, and the rear end of the first radial elastic band is fixedly connected to the latitudinal elastic band.

[0011] In one embodiment, the outer and inner sides of the first radial elastic band are respectively made of Velcro and skin-friendly material.

[0012] In one embodiment, the second radial elastic band has a left end and a right end. The left end of the second radial elastic band is non-detachably fixed to the weft elastic band, and the right end of the second radial elastic band is pasted around the weft elastic band and then attached to the second radial elastic band itself by means of Velcro with adjustable position.

[0013] In one embodiment, the second radial elastic band has a left end and a right end, and the left end and the right end of the second radial elastic band are both wrapped around the weft elastic band and then attached to the second radial elastic band itself by means of Velcro with adjustable adhesive position.

[0014] In one embodiment, the outer and inner surfaces of the second radial elastic band are respectively made of magic skin-friendly and skin-friendly surfaces.

[0015] In one embodiment, a wire fixing strap is further included. The wire fixing strap is connected to the rear end of the first radial elastic band. A hook and loop fastener is provided on one side of the wire fixing strap. One end of the hook and loop fastener is fixed to the wire fixing strap, and the other end is used to be attached to the outer surface of the wire fixing strap by hook and loop fastener.

[0016] In one embodiment, a wire fixing strap is further included, which is connected to the rear end of the first radial elastic band, and binding ropes are provided on both sides of the wire fixing strap.

[0017] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] This invention features a weft elastic band with both ends connected by Velcro, and a radial elastic band with at least one end wrapped around the weft elastic band and also connected to the radial elastic band by Velcro. Because of the Velcro fastening method, the fastening position is adjustable, allowing for adjustment of both the circular weft elastic band and the semi-circular radial elastic band. This enables the overall size of the fixation cap to be adjusted according to the size of the child's head, preventing the cap from being too large and causing electrode detachment, or too small and causing pressure sores on the child's head. Furthermore, the weft elastic band that adheres to the forehead can be adjusted to a suitable size, preventing it from pressing too tightly on the forehead and thus avoiding forehead pressure sores.

[0028] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0029] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0030] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0031] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0032] Please see Figures 1 to 7 This utility model describes an adjustable EEG elastic fixation cap, comprising a ring-shaped latitudinal elastic band 10 placed latitudinally along the head and a semi-ring-shaped radial elastic band placed radially along the head; the two ends of the latitudinal elastic band 10 are connected by Velcro with adjustable fastening; the two ends of the radial elastic band are connected to the latitudinal elastic band 10, and at least one end of the radial elastic band passes around the latitudinal elastic band 10 and is connected to the radial elastic band itself by Velcro with adjustable fastening; the radial elastic band is divided into a first radial elastic band 20 placed on the head along a first radial direction and a second radial elastic band 30 placed on the head along a second radial direction, the first radial direction being perpendicular to the second radial direction, and the first radial direction being a radial direction from the forehead to the back of the head.

[0033] The latitudinal elastic band 10 is used to press on the forehead of the child; the first radial elastic band 20 is used to press on the first electrode piece placed on the head of the child along the first radial direction; and the second radial elastic band 30 is used to press on the second electrode piece placed on the head of the child along the second radial direction. By fixing the electrode piece placed on the head with the first radial elastic band and the second radial elastic band 30, the electrode piece can be prevented from moving.

[0034] This invention features a weft elastic band with both ends connected by Velcro, and a radial elastic band with at least one end wrapped around the weft elastic band and also connected to the radial elastic band by Velcro. Because of the Velcro fastening method, the fastening position is adjustable, allowing for adjustment of both the circular weft elastic band and the semi-circular radial elastic band. This enables the overall size of the fixation cap to be adjusted according to the size of the child's head, preventing the cap from being too large and causing electrode detachment, or too small and causing pressure sores on the child's head. Furthermore, the weft elastic band that adheres to the forehead can be adjusted to a suitable size, preventing it from pressing too tightly on the forehead and thus avoiding forehead pressure sores.

[0035] In one embodiment, such as Figure 3 As shown, the weft elastic band 10 includes a weft band body and an inner hook and loop fastener layer 14 disposed at one end of the weft band body. The weft band body includes a skin-friendly layer 11, an elastic layer 12, and an outer hook and loop fastener layer 11 arranged sequentially from the inside to the outside. The inner hook and loop fastener layer 14 is located on the side of the skin-friendly layer 11 facing away from the elastic layer 12. The skin-friendly layer 11 increases the comfort of the weft elastic band 10, and the elastic layer 12 makes the weft elastic band 10 elastic. The outer hook and loop fastener layer 11 and the inner hook and loop fastener layer 14 are arranged such that the two ends of the weft elastic band 10 can be connected by the inner hook and loop fastener layer 14 being attached to the outer hook and loop fastener layer 11. Moreover, by changing the attachment position of the inner hook and loop fastener layer 14 on the outer hook and loop fastener layer 11, the size of the semi-circular weft elastic band 10 can be adjusted. Further, the elastic layer 12 is preferably a latex pad layer.

[0036] The first radial elastic band 20 needs to cover the first electrode pads placed on the head along the first radial direction so that the first electrode pads can be firmly attached to the child's head. If the width of the first radial elastic band 20 is sufficient to cover all the first electrode pads placed on the child's head along the first radial direction, then one band is sufficient. Figure 1 As shown; if the width of the first radial elastic band 20 cannot completely cover all the first electrode pads placed along the first radial direction on the child's head, then one or more bands are installed until the number of bands installed covers all the first electrode pads placed along the first radial direction on the child's head. Therefore, the width and number of the first radial elastic bands 20 are set according to actual needs. Figure 1 and Figure 4 As shown, the first radial elastic band 20 has a front end 21 near the child's forehead and a rear end 22 near the back of the child's head. In one embodiment, the front end 21 of the first radial elastic band 20 passes around the weft elastic band 10 and is connected to the first radial elastic band 20 itself via Velcro with adjustable adhesion. The rear end 22 of the first radial elastic band 20 is fixedly connected to the weft elastic band 10. By changing the adhesion position of the rear end 22 of the first radial elastic band 20 on the first radial elastic band 20, the size of the semi-circular structure formed by the first radial elastic band 20 can be adjusted. In this case, the outer surface of the first radial elastic band 20 is made of Velcro.

[0037] Furthermore, the outer and inner sides of the first radial elastic band 20 are respectively made of Velcro and skin-friendly material. The outer side of the first radial elastic band 20 is made of Velcro, which allows the end of the first radial elastic band 20 to be pasted onto the first radial elastic band 20 itself after passing over the weft elastic band 10, and the pasting position can be adjusted at will. The inner side of the first radial elastic band 20 is made of skin-friendly material because the inner side of the first radial elastic band 20 will come into contact with the skin of the head, and this setting can increase the comfort of the first radial elastic band 20.

[0038] In the first embodiment, as Figure 1 As shown, there are three second radial elastic bands 30, which are arranged at intervals along the first radial direction to fix three electrode plates placed sequentially along the first radial direction.

[0039] In one embodiment, such as Figure 5 As shown, the second radial elastic band 30 has a left end 31 and a right end 32. The left end 31 of the second radial elastic band 30 is non-detachably fixed to the weft elastic band 10, and the right end 32 is wrapped around the weft elastic band 10 and then attached to the second radial elastic band 30 itself using Velcro. By changing the attachment position of the right end 32 on the second radial elastic band 30 itself, the size of the semi-annular structure formed by the second radial elastic band 30 can be adjusted. In other feasible embodiments, such as... Figure 6 As shown, the left end 31 and the right end 32 of the second radial elastic band 30 can be arranged to pass around the weft elastic band 10 and then be attached to the second radial elastic band 30 itself by Velcro with adjustable adhesive position. By changing the adhesive position of the left end 31 and the right end 32 of the second radial elastic band 30, the size of the semi-ring structure formed by the second radial elastic band 30 can be adjusted.

[0040] Furthermore, the outer and inner sides of the second radial elastic band 30 are respectively made of Velcro and skin-friendly surfaces. The outer side of the second radial elastic band 30 is made of Velcro, which allows the end of the second radial elastic band 30 to be wrapped around the weft elastic band 10 and then attached to the second radial elastic band 30 itself. Moreover, the attachment position can be adjusted at will. The inner side of the second radial elastic band 30 is made of skin-friendly surface because the inner side of the second radial elastic band 30 will come into contact with the head skin. This setting can increase the comfort of the second radial elastic band 30.

[0041] Furthermore, the first radial elastic band 20 and the second radial elastic band 30 are connected by Velcro so that the second radial elastic band 30 can be further fixed by the first radial elastic band 20, making it less prone to positional changes, and allowing the second radial elastic band 30 to better fix the second electrode sheet.

[0042] In one embodiment, the adjustable EEG elastic fixation cap further includes a wire fixing strap 40, such as... Figure 1 and Figure 4As shown, with the rear end 22 of the first radial elastic band 20 fixedly connected to the weft elastic band 10, a wire fixing band 40 is connected to the rear end 22 of the first radial elastic band 20. A Velcro strap 50 is provided on one side of the wire fixing band 40. One end of the Velcro strap 50 is fixed to the wire fixing band 40, and the other end is attached to the outer surface of the wire fixing band 40 via Velcro, thereby fixing the conductive wires used for electrically connecting the electrodes to the wire fixing band 40 and avoiding tangling of the conductive wires. In other feasible embodiments, such as... Figure 7 As shown, binding ropes 60 replace Velcro straps 50. Binding ropes 60 are provided on both sides of the wire fixing strap 40. The wires of the electrode are fixed to the wire fixing strap 40 by connecting the binding ropes 60 on both sides of the wire fixing strap 40.

[0043] In one embodiment, the thread fixing strap 40 is non-detachably fixed to the weft elastic band 10. In other feasible embodiments, the thread fixing strap 40 may be detachably connected to the weft elastic band 10. For example, the thread fixing strap 40 is connected to the weft elastic band 10 via a snap fastener. Another example is that the thread fixing strap 40 and the weft elastic band 10 are connected via Velcro.

[0044] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
