Description

Technical Field

[0001] The utility model belongs to the technical field of electroencephalogram electrode wires, in particular to an electroencephalogram electrode wire storage device. Background Art

[0002] An EEG electrode cable, also known as an EEG electrode cable, is a medical device used to record EEG signals. It usually consists of multiple conductive electrodes that are fixed to the scalp to detect electrical activity in the cerebral cortex.

[0003] The designs and materials of EEG electrode wires vary, but they are usually made of soft and durable materials to ensure comfort and safety. After the electrode wires are used, they need to be aligned and stored using a wire reel or a storage box. When the electrode wires are rolled up and stored by the rotating column, when there are many electrode wire bundles, it is easy for the wire reel to roll up and store one wire bundle, and then the rotating column is rotated again to roll up another wire bundle. The stored wire bundle becomes loose on the surface of the wire reel due to the rotation of the rotating column. In order to prevent the stored wire bundle from becoming loose due to the rotation of the rotating column, an EEG electrode wire storage device is designed. The device rolls up and stores the wire bundle by using a rotating column, a convex column and a wire reel, and under the action of the first triangular head, the second triangular head and the trapezoidal sheet, the wire reel and the convex column can be misaligned, so that the wire reel stored on one side cannot rotate synchronously with the rotating column and the convex column, so that the stored wire bundle will not become loose due to the rotation of the rotating column.

The surface of the limiting rod 11 is slidably connected to the inner cavity of the limiting tube 10, and the inner cavity of the support frame 1 is provided with a connecting column 13. The connecting column 13 is located at the center position of the inner cavity of the support frame 1, and the left and right ends of the connecting column 13 are respectively fixedly connected to the convex column 3 on the left and the rotating column 2 on the right.

[0025] Embodiment 2:

[0026] Figure 1-5The present invention shows an embodiment of an EEG electrode wire storage device, which includes: a support frame 1: the left and right sides of the inner cavity of the support frame 1 are rotatably connected with a rotating column 2, the right sides of the two rotating columns 2 are fixedly connected with a convex column 3, the surfaces of the rotating column 2 and the convex column 3 are slidably connected with a winding drum 4, the surface of the convex column 3 is provided with four circular grooves, the inner cavity of the circular groove is slidably connected with a supporting sheet 5, a spring 6 is welded between the bottom end of the supporting sheet 5 and the inner wall of the circular groove, a triangular head 7 is welded on the top of the supporting sheet 5, four triangular heads 8 are welded on the inner walls of the two winding drums 4, four trapezoidal sheets 9 are welded on the inner walls of the two winding drums 4, and the trapezoidal sheets 9 fits the surface of the triangular head 8, a limiting groove is provided on the surface of the rotating column 2, and the inner wall of the winding drum 4 is fixedly connected to the limiting ring 12.

When the winding drum 4 on the left has completed storing the electrode wire, the two winding drums 4 are pushed to slide to the left.

At this time, the trapezoidal piece 9 on the left side is staggered with the triangle head 1 7 on the left side, and then the winding drum 4 on the right side is driven to reel in the electrode wire, so that the wire harness after storage will not be loosened due to the rotation of the rotating column 2.

[0028] To sum up: the EEG electrode wire storage device slides to the left by moving the two winding drums 4. Under the special shapes of the triangular head 1 7 and the triangular head 2 8, the triangular head 2 8 pushes the triangular head 1 7 to slide downward in the inner cavity of the circular groove.
