Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a packaging bag for an electroencephalogram (EEG) monitoring electrode box. Background Technology

[0002] Electroencephalography (EEG) monitoring is a crucial technique for epilepsy diagnosis, brain function assessment, and neuroscience research. It uses multi-channel electrodes to acquire EEG signals, enabling continuous recording of brain electrical activity. With the widespread adoption of high-density electrode arrays and long-range monitoring technologies, the number of electrodes required for a single monitoring session can reach dozens to hundreds, posing significant challenges to the resulting circuit management systems. Currently, in clinical and research settings, EEG monitoring devices typically consist of multiple electrode boxes (such as amplifier boxes and signal conversion modules) and densely packed electrode leads, with the ends of the leads connected to the electrodes via plug-in interfaces. However, existing technologies lack standardized design for circuit layout, leading to the following prominent issues.

[0003] First, the physical management of the wiring is inefficient. During monitoring, electrode leads extending from the patient's head need to be centrally connected to the electrode box. However, due to the lack of a modular wiring solution, a large number of cables are often stacked haphazardly or scattered directly on the bed or hanging from the bedside bracket. When patients undergo imaging examinations such as MRI or CT, the wiring connection needs to be temporarily disconnected. During the reconnection process after the examination, problems such as wire tangling and misalignment of interfaces are very likely to occur. In addition, long-term friction between the cables and bed sheets and the patient's limbs can easily produce motion artifacts, and even cause poor electrode contact or detachment due to traction, which seriously affects the continuity of signal acquisition. Second, the messy wiring directly increases the risks and costs of clinical operation. Disorganized cables not only hinder medical staff from quickly locating faulty electrodes, but may also delay clinical treatment in emergency situations. The lack of dedicated storage tools or marking systems during repeated disassembly and assembly further aggravates the risk of interface contamination. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a packaging bag for EEG monitoring electrode boxes, which effectively solves the problem of inconvenient storage of EEG monitoring electrode boxes and circuits.

[0005] The technical solution is as follows: This utility model includes a wrapping cloth in the left-right direction. An elastic positioning block is fixed to the right side of the front end of the wrapping cloth. The positioning block has a placement groove with an opening facing forward. The lower side of the placement groove is trapezoidal with a larger upper side and a smaller lower side, and the lower end is connected to the outside. Multiple stop bars are fixed in the placement groove, evenly distributed in the left-right direction and vertically. Multiple rectangular rings are fixed in the placement groove, evenly distributed in the left-right direction. Multiple stop bars are located between two adjacent rectangular rings. Multiple positioning strips corresponding to the rectangular rings are fixed in the placement groove. The upper end of the positioning strip is fixed with a hook that can cooperate with the rectangular ring. The positioning strip is made of elastic material and has a clearance groove that runs through the front. Pressure strips located below the stop bars are fixed on the left and right sides of the placement groove. The two pressure strips are horizontally oriented and their opposite ends can be connected to each other. A gathering strip located below the pressure strips is fixed in the placement groove.

[0006] This invention features a regional layered design for orderly wire arrangement, preventing tangling and positioning of multiple electrode boxes. The dual constraint of the pressure band and the coiling band significantly reduces cable sway. A trapezoidal placement slot, combined with an elastic positioning block, ensures the electrode boxes are stable and can be quickly assembled and disassembled. The electrode wires can also be coiled downwards and extended. Velcro wrapping provides physical shielding, reducing interface exposure. The interlocking locking mechanism of the insertion block and limiting rod enhances the reliability of the pressure band connection and prevents accidental detachment by children. The combined coiling scheme of the connecting ring and adhesive tape accommodates different numbers of cables, ensuring a stable wire bundle shape. The entire device is portable and suspended via a hook, meeting the clinical needs of patient care and examinations. This design is simple, easy to operate, innovative, and highly practical.

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 5The package includes a wrapping cloth 1 extending in the left-right direction. A flexible positioning block 2 is fixed to the right front end of the wrapping cloth 1. The positioning block 2 has a forward-facing placement groove 3. The lower side of the placement groove 3 is trapezoidal, wider at the top and narrower at the bottom, and its lower end is connected to the outside. Multiple baffles 4 are evenly distributed in the left-right direction and vertically in the placement groove 3. Multiple rectangular rings 5 ​​are evenly distributed in the left-right direction and fixed in the placement groove 3. Each baffle 4 is located between two adjacent rectangular rings 5. Multiple positioning straps 6 are fixed in the placement groove 3, each corresponding to one of the rectangular rings 5. The upper end of the positioning strap 6 is fixed with a hook 7 that can cooperate with the rectangular rings 5. The positioning strap 6 is made of elastic material and has a through-hole chute 8 on its front side. Pressure straps 9 are fixed on the left and right sides of the placement groove 3, located below the baffles 4. The two pressure straps 9 are horizontally oriented and their opposite ends can be connected to each other. A gathering strap 10 is fixed in the placement groove 3, located below the pressure straps 9.

[0014] In order to facilitate the covering of the positioning block 2 and the placement groove 3 by the wrapping cloth 1, the front left side of the wrapping cloth 1 is provided with a Velcro closure, and the front right side of the wrapping cloth 1 is provided with a Velcro closure that can be glued to the Velcro closure.

[0015] To facilitate the suspension of this device, an arc-shaped hook 11 is fixed to the upper end of the positioning block 2.

[0016] To increase stability, the positioning block 2 is fixed with multiple pressing bands 12 evenly distributed in the left and right direction. The front side of the pressing band 12 and the right end of the positioning block 2 are fixed with a male buckle 13, and the rear side of the pressing band 9 is provided with a female buckle 14 that can cooperate with the male buckle 13.

[0017] To facilitate the connection of the two pressure bands 9, connecting blocks 15 are fixed at opposite ends of the two pressure bands 9 respectively. A slot 16 with an opening facing right is provided on the left connecting block 15, and an inverted L-shaped insert 17 is fixed on the right connecting block 15. A limiting rod 18 is slidably connected to the left connecting block 15. The upper end of the limiting rod 18 passes through the connecting block 15 on its corresponding side and the lower side contacts the stepped surface of the insert 17.

[0018] To facilitate the movement of the limiting rod 18, a pressure groove 19 is provided on the connecting block 15 on the left side. A pressure plate 20 is fixed to the left end of the limiting rod 18. The pressure plate 20 is located in the pressure groove 19 and its upper end is connected to the upper side wall of the pressure groove 19 via a V-shaped elastic sheet 21.

[0019] To facilitate the use of the gathering strap 10, a connecting ring 22 is provided on the lower side of the placement groove 3, located to the left of the gathering strap 10. The free end of the gathering strap 10 passes through the connecting ring 22 and is provided with an adhesive sticker.

[0020] In use, the electrode box is inserted longitudinally into the placement groove 3 of the positioning block 2, so that the bottom of the electrode box contacts the bottom of the positioning band 6. Since the positioning band 6 is elastic, the electrode box is initially positioned by the cooperation of the hook 7 and the rectangular ring 5. Then, through the above process, multiple electrode boxes are placed one by one between the stop bars 4. Then, each electrode wire is inserted into the electrode box in sequence according to the left and right sections, and the multiple electrode wires are arranged downwards and extend from both sides of the positioning band 6. Then, the multiple pressing bands 12 are connected to each other by the snaps on the pressing band 12 to further position the electrode wires. Since the electrode box is shaped like a large top and a small bottom, the lower side of the electrode box can extend from the relief groove 8 on the positioning band 6.

[0021] After straightening the wire bundle downwards, gather the left and right pressure bands 9 towards the center and lock them in place by engaging the insert 17 with the slot 16. Press down the elastic sheet 21 on the limiting rod 18 so that the lower end abuts against the stepped surface of the insert 17 to prevent detachment. Fold the free end of the gathering band 10 back through the connecting ring 22 and then stick it tightly with adhesive tape to form a closed loop. At this time, the electrode wire is located in the closed loop formed by the gathering band 10 and extends out from the lower opening of the placement slot 3. Wrap the wrapping cloth 1 around to the left and cover the placement slot 3 by the adhesion of the Velcro and the sub-adhesive. Lift the hook 11, disassemble the whole thing, and hang it on the bracket for easy movement and placement during inspection.

[0022] This utility model, through the design of positioning straps, wrapping cloth, positioning blocks, stop bars, and placement slots, achieves regional layered design during use, enabling orderly arrangement of wires and avoiding tangling. It also positions multiple electrode boxes, and the dual constraint of the pressure strap and the coiling strap significantly reduces cable sway. The trapezoidal placement slot, combined with the elastic positioning block, ensures the electrode boxes are stable and can be quickly assembled and disassembled, while allowing the electrode wires to be coiled downwards. The Velcro wrapping cloth provides physical shielding, reducing interface exposure. The interlocking locking of the insertion block and limit bar enhances the reliability of the pressure strap connection and prevents accidental detachment by children. The combined coiling scheme of the connecting ring and adhesive tape adapts to different numbers of cables, ensuring a stable wire bundle shape. The entire device is portable and suspended via a hook, meeting the clinical needs of patient care and examination. This structure is simple, easy to operate, innovative in design, and highly practical.
