Abstract
Description
Technical Field
[0001] The utility model relates to the field of electrode caps, in particular to an electroencephalogram electrode cap with a wire management function. Background Art
[0002] The traditional EEG electrode cap mainly includes a cap body, an electrode wire and an electrode holder. The electrode sensing end of the electrode wire is fixed on the electrode holder of the cap body, and the wire of the electrode wire is led out from the base end of the electrode holder. Most existing wire management solutions only simply bundle the wire direction of the electrode wire, such as an elastic band sewn on the cap or a plastic ring. The wire can be pulled at will, the electrode wire still slides, and there is no other force support point for the wire. In addition, if a plastic wire is used as a wire clamping wire, it is easy to be too tight, and the wire is easy to be damaged at the outlet. Therefore, in the prior art, during the test process, the lead-out point of the wire connected to the electrode holder end is easily pulled by the rear end, causing the instability of the test signal, and during the cleaning process, the lead-out point of the wire connected to the base end is pulled strongly, causing the wire to be easily damaged here. Utility Model Content
[0003] The utility model mainly aims to provide an electroencephalogram electrode cap with a wire-managing function, which can manage wires and keep the "electrode-scalp" contact stable when pulling the wires.
[0004] The technical solution adopted by the utility model is:
[0005] Provided is an electroencephalogram electrode cap with a wire management function, comprising a cap body and electrode wires, wherein a plurality of electrode seats are arranged on the cap body, and the electrode wires are fixed on the cap body through the electrode seats; the wires of each electrode wire transmit the electroencephalogram signal sensed by the electrode;
[0006] The cap body is also fixed with a plurality of wire management fixings, through which the wire of at least one electrode wire passes. When the wire is pulled, the pulling force is transmitted to the wire management fixing and is cut off.
[0007] According to the above technical solution, the wire management fixture is arranged on the cap body according to a certain preset distance, and fixes several nearby wires.
[0008] According to the above technical solution, at least one accommodating space is provided on the wire management fixture, and the accommodating space covers the wire passing through the accommodating space.
[0009] According to the above technical solution, the accommodating space is a variable space enclosed by two parts that can be opened and closed.
[0010] In accordance with the above technical solution, the wire management fixture is a press-type buckle, which is provided with a plurality of accommodating grooves inside and a pressure cover outside. The wires are placed in the accommodating grooves along the length direction and the wires are pressed by the pressure cover.
[0011] According to the above technical solution, the cable management fixing member is a locking member.
[0012] According to the above technical solution, the locking member includes a base fixed on the cap body and a locking buckle placed on the base. One side of the locking buckle is open, and the middle is two wiring spaces separated by a cross bar. The wire enters the locking buckle from the opening, passes through the cross bar in the two wiring spaces, and is fixed between the locking buckle and the base.
[0013] According to the above technical solution, the wire management fixture is sewn to the cap body by sewing thread or adhered to the cap body by waterproof adhesive.
[0014] According to the above technical solution, the cable management fixing piece is made of a soft elastic material with a certain hardness.
[0015] According to the above technical solution, the wires are fixed at certain intervals by wire management fixtures.
[0016] According to the above technical solution, the electrode is a dry electrode, a semi-dry electrode or a wet electrode.
[0017] The beneficial effects of the utility model are as follows: the utility model fixes a plurality of wire-manipulating fixtures on the electroencephalogram electrode cap, each wire-manipulating fixture at least limits the wire of one electrode wire, and when the wire is pulled, the pulling force is transmitted to the wire-manipulating fixture and cut off. It can be seen that the newly added wire-manipulating fixture can not only manage the wire but also prevent the electrode wire from moving when the wire is pulled, thereby maintaining the "electrode-scalp" contact stability; in addition, the wire-manipulating fixture is used as a support point to withstand the force generated by pulling the wire, so that the lead-out point of the wire at the base end of the electrode wire is not easily damaged by pulling, thereby improving the stability of the contact point, and then improving the stability of the contact between the electrode and the scalp, making the test signal more stable, and improving the service life of the electrode cap.
[0018] Furthermore, the wire management fixtures are arranged on the cap body at a certain preset distance and fix several nearby wires. The wire management fixtures are reasonably arranged according to the distance so that the wires can be reasonably bundled and not be in a disorder.
[0019] Furthermore, by providing an accommodating space on the wire management fixture, the accommodating space can be either a fixed space or a variable space, and can be adjusted according to the number of wires passing through.
[0020] Furthermore, the wire management fixture is configured to fix the wire in a manner such as a press-type buckle, a lock buckle or a snap buckle, so that the force relief effect when the wire is pulled can be well achieved in a simple manner.
[0021] Furthermore, the wire management fixing piece is made of a soft elastic material with a certain hardness, which can better unload the force and adapt to the curvature of the electrode cap, making it more comfortable to wear.
[0022] Furthermore, the wires are fixed by wire management fixtures at certain intervals, so that longer wires can be better bundled and more clearly organized, and there are corresponding support points as unloading points when being pulled at different positions.
[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0041] like Figure 1 As shown, the EEG electrode cap with wire management function of this embodiment includes a cap body 10 and an electrode wire, and the electrode wire includes an electrode 12 and a wire 13. A plurality of electrode seats 11 are arranged on the cap body 10, and the electrode wire is fixed on the cap body 10 through the electrode seat 11; the wire of each electrode wire transmits the EEG signal sensed by the electrode; a plurality of wire management fixings 14 are also fixed on the cap body 10, and the wire of at least one electrode wire passes through the wire management fixing 14, and when the wire is pulled, the pulling force is transmitted to the wire management fixing 14 and cut off.
[0042] like Figure 1 As shown, the wire management fixture 14 can be arranged on the cap body 10 at a certain preset distance and fix several nearby wires. The cap body 10 can be made of a variety of cap materials such as a fabric cap, an elastic fabric cap, a silicone cap, etc. The electrode 12 can be a dry electrode, a semi-dry electrode, or a wet electrode, etc.
[0043] like Figure 2A , 2B As shown, at least one accommodating space 142 is defined on the wire management fixture 14 , and the accommodating space 142 covers the wire 13 passing therethrough.
[0044] like Figure 2A-2EAs shown, the accommodating space 142 is a variable space surrounded by two parts 143 that can be opened and closed. The two parts 143 that can be opened and closed adjust the size of the accommodating space 142 according to the wire diameter and number of the coated wires, that is, the size of the variable space is adjusted to adapt to wires of different wire diameters and numbers. When the two parts are opened, the wires can be placed conveniently. The two parts 143 that can be opened and closed can change the size of the accommodating space 142 by gluing them at different positions, or the two parts 143 that can be opened and closed are deformable materials with a certain hardness and memory, so that the wires can be closed and fixed at any position.
[0045] like Figure 2B As shown, the accommodation space 142 of the wire management fixture 14 may include a plurality of vortex wire bundle barrel-shaped structures, and the vortex opening is larger so that the wire can slide into the wire bundle cavity from the opening, and this structure prevents the wire from sliding out, thereby improving the assembly production efficiency of the electrode cap without threading the wire. The accommodation space 142 of the wire management fixture 14 may be at a certain angle to the wire outlet direction, so that when the wire is pulled, the wire management fixture 14 can better play a role in unloading force.
[0046] like Figure 2B and Figure 6 As shown, the bottom of the wire management fixture 14 is provided with a connecting portion 141, such as an I-shaped groove structure, which is clamped on the cap body 10, and the vortex opening can be slightly tilted upward at a certain angle and can be slightly deformed, and the wire slides from the vortex opening into the accommodating space 142. Or as Figure 7 As shown, the bottom of the cable management fixture 14 is connected to the cap body 10 via a buckle, and the buckle may include a female buckle 14-1 and a sub-buckle 14-2.
[0047] like Figure 2C , 2D As shown, the accommodating space 142 has a certain angle with the outlet direction. After the wires 13 in different directions pass through the wire management fixture 14, the direction of the wires 13 at the outlet end is changed, and the wires 13 are bent. The outer side of the wires is squeezed and rubbed with the side wall edge of the wire management fixture 14 due to the bending of the wires, generating a large friction force. The stronger the rear end pulling force, the greater the friction force, and the less likely it is for the wires 13 and the wire management fixture 14 to slide relative to each other, thereby achieving the purpose of fixing the wires 13 at the point of the wire management fixture 14.
[0048] In addition to making the accommodating space 142 and the wire outlet direction form a certain angle to cause the wire to squeeze and rub against the wire management fixture, the accommodating space 142 itself can have a certain bending angle to cause the wire to squeeze and rub against the side wall inside the wire management fixture, such as Figure 2E shown.
[0049] Furthermore, in addition to applying a horizontal extrusion friction force to the wire in the above embodiment, a vertical extrusion friction force may also be applied to the wire. Figure 3 As shown, the wire management fixture 14 is a press-type buckle, which is provided with a plurality of accommodating grooves inside and a pressure cover outside, and the wire 13 is placed in the accommodating groove along the length direction, and the pressure cover is used to press the wire 13. When the wire is pulled, the pressure cover can apply a vertical extrusion friction force to the wire, thereby helping the electrode wire to unload force.
[0050] like Figure 4A , 4B As shown, in another embodiment of the present invention, the wire management fixing member 14 can also be a locking member. The locking member includes a base 144 fixed on the cap body 10 and a locking member 145 placed on the base 144. An opening 1451 is set on one side of the locking member, and the middle is separated into two wire bundle spaces 1453 by a cross bar 1452. The wire 13 enters the locking member 145 through the opening 1451, passes through the cross bar 1452 in the two wire bundle spaces 1453, and is fixed between the locking member 145 and the base 144.
[0051] like Figure 5 As shown in FIG. 1 , another embodiment of a cable fixing member 14 is provided with two through holes, and the wire 13 passes through one of the through holes and passes through the other through hole. The connection between the two through holes has a certain thickness, and the edge of the through hole also has a certain thickness, so that when the wire passes through the two through holes, a certain friction force is generated with the edge of the through hole and the connection, so that the tension generated when the wire is pulled is borne by the cable fixing member 14, and the tension is transmitted to the cable fixing member 14 and cut off. Based on this embodiment, as Fig. 8A As shown, the connection between the two through holes can be directly fixed on the cap body 10 by means of a suture 15. Figure 8B As shown, the wire fixing member 14 is made of a soft material with a certain hardness, and two holes are opened on both sides of the soft elastic material and then sewn on the cap body 10. It can be understood that if the material allows, the wire fixing member 14 can also be attached to the cap body 10 by waterproof glue.
[0052] In summary, the utility model fixes multiple wire management fixtures on the EEG electrode cap, each wire management fixture limits the wires of one or more electrode wires. When the wires are pulled, the pulling force is transmitted to the wire management fixture and cut off, so that the lead-out points of the wires and the base ends of the electrode wires are not easily damaged by pulling, thereby improving the stability of the contact points, making the test signals more stable, and increasing the service life of the electrode cap.
[0053] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
