Description

Technical Field

[0001] The utility model relates to the technical field of non-invasive electroencephalogram (EEG), and in particular to a tray structure for packaging a non-invasive electroencephalogram (EEG) sensor. Background Art

[0002] The EEG sensor is a dual-frequency EEG sensor that can reflect the excitation or inhibition state of the cerebral cortex. It can provide detection and evaluation of EEG consciousness state to meet more medical clinical needs. For example, a non-invasive EEG sensor disclosed in a Chinese patent (CN211066607U) mainly consists of a skeleton, a flexible circuit board and multiple electrode sheets. Since the flexible circuit board itself is a flexible material, small and thin electrode sheets are attached to the flexible circuit board, and the overall structure of the non-invasive EEG sensor is unstable.

[0003] At present, the packaging of non-invasive EEG sensors usually involves folding the flexible circuit board and placing it in a packaging bag. During handling and transportation, the simply packaged non-invasive EEG sensors are squeezed and impacted, which can easily lead to excessive folding and damage of the flexible circuit board.

Therefore, it should not be understood as a limitation on the present invention.

[0025] In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0026] See also Figure 1-6 As shown, the embodiment of the utility model provides a tray structure for packaging non-invasive EEG sensors. The tray structure is used to limit and fix the non-invasive EEG sensors when packaging them, so as to prevent the non-invasive EEG sensors from being damaged due to excessive folding during handling and transportation. Figure 1As shown, the non-invasive EEG sensor mainly includes a flexible circuit board 1, a plurality of electrode sheets 2 attached to the surface of the flexible circuit board 1, and a plug sheet 3 installed at one end of the flexible circuit board 1. The tray structure is mainly used to limit and fix the flexible circuit board 1, the electrode sheets 2 and the plug sheet 3. Figure 3 , Figure 4 As shown, the tray structure includes a tray body 4, which has an upper surface 41 and a lower surface 42. The upper surface 41 is provided with a plurality of electrode slots 43, which are used to limit and fix the electrode sheet 2, and the lower surface 42 is provided with an insert slot 44, which is used to limit and fix the insert sheet 3.

[0027] See also Figure 5 , Figure 6 As shown, after the non-invasive EEG sensor is installed on the tray body 4, the flexible circuit board 1 is attached to the upper surface 41 of the tray body 4, the electrode sheets 2 are fixedly engaged in the corresponding electrode slots 43, and the plug-in sheet 3 is fixedly engaged in the plug-in slot 44. The electrode sheets 2 and the plug-in sheet 3 will not be squeezed and impacted by external forces, and the flexible circuit board 1 is laid flat on the upper surface 41 of the tray body 4, reducing unnecessary folding. Under the protection of the tray structure, the non-invasive EEG sensor is difficult to be excessively folded and damaged during handling and transportation.

[0028] See also Figure 4 As shown, in one embodiment, a buckle 5 is respectively provided on the two side edges of the insert slot 44, and the two buckles 5 jointly limit and fix the insert 3 in the insert slot 44, so that the insert 3 can be firmly positioned in the insert slot 44, and it is also convenient to remove the insert 3 from the insert slot 44.

[0029] See also Figure 1 As shown, the flexible circuit board 1 includes a straight segment 11 and an arc segment 12. One end of the straight segment 11 is integrally connected to the middle of the arc segment 12. The other end of the straight segment 11 is installed with a plug 3. At least the arc segment 12 is attached to the upper surface 41. The straight segment 11 is bent but not folded. Specifically, a middle electrode group 6 and single electrode sheets 2 respectively connected to the two ends of the middle electrode group 6 are provided on the arc segment 12. The middle electrode group 6 includes five electrode sheets 2 arranged in sequence. It can be understood that the electrode card slot 43 on the upper surface 41 of the tray body 4 is adapted to the electrode sheet 2 on the arc segment 12, so that the flexible circuit board 1 can be laid flat on the upper surface 41 of the tray body 4, as shown in FIG. Figure 5 shown.

[0030] Furthermore, in one embodiment, an anti-folding portion 9 is provided at the edge of the tray body 4 , and the straight line segment 11 is bent and fits on the surface of the anti-folding portion 9 , so that the straight line segment 11 will not fold even if the bent portion is squeezed.

[0031] For further information, see Figure 4 As shown, in one embodiment, the pallet body 4 is further provided with reinforcing ribs, which protrude from the lower surface 42 of the pallet body 4. The reinforcing ribs include annular segment reinforcing ribs 7 and straight segment reinforcing ribs 8. The annular segment reinforcing ribs 7 are provided near the edge of the pallet body 4, and the straight segment reinforcing ribs 8 are located inside the annular segment reinforcing ribs 7. The straight segment reinforcing ribs 8 and the annular segment reinforcing ribs 7 provide additional rigid protection for the pallet body 4, ensuring that the pallet body 4 has strong anti-extrusion and anti-bending capabilities.

[0032] It can be understood that in order to further improve the fixing effect of the tray body 4 on the non-invasive EEG sensor, a detachable cover (not shown in the figure) can be designed on the upper surface 41 and the lower surface 42 of the tray body 4 respectively. After the non-invasive EEG sensor is installed on the tray body 4, the covers on the upper surface 41 and the lower surface 42 are respectively covered to prevent the non-invasive EEG sensor from being squeezed and impacted by external forces. However, the cover will increase the packaging volume and cost, and whether to use the cover can be selected according to actual conditions.

[0033] The above detailed description of the preferred embodiments of the utility model should not be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
