Description

Technical Field

[0001] This utility model relates to the field of physiological detection technology, specifically a multi-lead electrode device for physiological detection. Background Technology

[0002] A multi-lead electrode device is a medical device used to record and monitor bioelectrical signals, simultaneously recording electrophysiological activity across multiple channels. This device is widely used in cardiac electrophysiology, neuroscience, sleep research, and other fields requiring the monitoring of electrophysiological signals. The following are the main components and functions of a multi-lead electrode device.

[0003] When conducting physiological tests, multi-lead electrodes typically have multiple electrode wires, which are attached to various parts of the subject's body via electrode pads at the ends of the wires. However, in actual use, multiple electrode wires lack cable management mechanisms, and they are prone to tangling and knotting, which is inconvenient for use. Therefore, we have introduced a multi-lead electrode device for physiological testing. Utility Model Content

[0004] The purpose of this invention is to provide a multi-lead electrode device for physiological testing, which can quickly organize and store multiple electrode wires, prevent multiple electrode wires from tangling and knotting during use, improve the convenience of use, and solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-lead electrode device for physiological testing includes multiple electrode wires and two U-shaped frames. The two U-shaped frames are symmetrically arranged, and one end of each U-shaped frame is rotatably connected by a hinge. The other end of each U-shaped frame is provided with a first rectangular groove and a second rectangular groove, respectively. The sidewall of the first rectangular groove is provided with a through hole, and a locking mechanism is provided between the first rectangular groove and the second rectangular groove. Multiple elastic sheets are fixedly provided on opposite sides of each of the two U-shaped frames. The multiple elastic sheets are evenly distributed, and the multiple electrode wires are respectively disposed in the multiple elastic sheets. The cross-section of each elastic sheet is C-shaped.

[0007] Furthermore, the locking mechanism includes a rectangular block, which is slidably disposed in the first rectangular groove near the through hole. One end of the rectangular block extends into the second rectangular groove. The groove wall of the second rectangular groove is provided with a locking block. The side wall of the rectangular block is provided with a locking groove that cooperates with the locking block. A push rod is slidably disposed in the through hole. One end of the push rod is fixedly connected to the rectangular block. A spring is fixedly disposed on the side of the rectangular block away from the through hole. The other end of the spring is fixedly connected to the first rectangular groove.

[0008] Furthermore, the locking block has a bevel on the side near the push rod.

[0009] Furthermore, the angle of the inclined plane is set to 45°.

[0010] Furthermore, a push plate is fixedly provided at the end of the push rod away from the spring.

[0011] Furthermore, the push plate sidewall is slidably provided with an anti-accidental touch frame, and one side of the anti-accidental touch frame is fixedly connected to the corresponding U-shaped frame.

[0012] Furthermore, both ends of the elastic sheet are equipped with rollers that rotate via pins.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This multi-lead electrode device for physiological testing comprises a U-shaped frame, electrode wires, elastic sheets, rollers, locking blocks, springs, rectangular blocks, an anti-accidental contact frame, a push plate, and a push rod. Pushing the push plate causes the rectangular block to compress the spring via the push rod. Simultaneously, the locking block moves to the outside of the locking slot. At this point, the two U-shaped frames can be opened via hinges. After connecting the electrode sheets at the ends of multiple electrode wires to designated positions on the body, the multiple electrode wires are respectively inserted into the multiple elastic sheets. Then, the two U-shaped frames are closed, and the rectangular block is inserted into the second rectangular slot. The inclined surface facilitates the locking block pushing the rectangular block downwards and compressing the spring. When the locking block aligns with the locking slot, the spring pushes the rectangular block, causing the locking block to engage with the locking slot. This allows for quick organization and storage of multiple electrode wires, preventing tangling and knotting during use, thus improving ease of use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution:

[0022] A multi-lead electrode device for physiological testing includes multiple electrode wires 2 and two U-shaped frames 1. One end of each electrode wire 2 is fixedly provided with an electrode sheet, and the other end of each electrode wire 2 is connected to a detection host. The two U-shaped frames 1 are symmetrically arranged, and one end of each U-shaped frame 1 is rotatably connected by a hinge. The other end of each U-shaped frame 1 is provided with a first rectangular groove and a second rectangular groove, respectively. The side wall of the first rectangular groove is provided with a through hole, and a locking mechanism is provided between the first rectangular groove and the second rectangular groove. Multiple elastic sheets 3 are fixedly provided on opposite sides of each of the two U-shaped frames 1. The multiple elastic sheets 3 are evenly distributed, and the multiple electrode wires 2 are respectively disposed in the multiple elastic sheets 3. The cross-section of the elastic sheet 3 is C-shaped, and both ends of the elastic sheet 3 are provided with rollers 4 rotatably via pins. The rollers 4 facilitate the user to insert the electrode wires into the elastic sheet 3.

[0023] The locking mechanism includes a rectangular block 7, which is slidably disposed within a first rectangular groove near the through hole. One end of the rectangular block 7 extends into a second rectangular groove, the groove wall of which is provided with a locking block 5. The side wall of the rectangular block 7 is provided with a locking groove that mates with the locking block 5. A push rod 10 is slidably disposed within the through hole, one end of which is fixedly connected to the rectangular block 7. A spring 6 is fixedly disposed on the side of the rectangular block 7 away from the through hole, the other end of which is fixedly connected to the first rectangular groove. The locking block 5 has an inclined surface near the push rod 10, with the angle of the inclined surface set at 45°. The inclined surface facilitates the locking block 5 to push the rectangular block 7 downward and compress the spring 6. A push plate 9 is fixedly disposed on the end of the push rod 10 away from the spring 6, facilitating the pushing of the push rod 10. An anti-accidental touch frame 8 is slidably disposed on the side wall of the push plate 9, one side of which is fixedly connected to a corresponding U-shaped frame 1, preventing the user from accidentally touching the push plate 9.

[0024] In use, push the push plate 9, which drives the rectangular block 7 to compress the spring 6 via the push rod 10. As the rectangular block 7 moves, the locking block 5 moves to the outside of the locking groove. At this time, the two U-shaped frames 1 can be opened by hinges. After the electrode plates at the ends of multiple electrode wires 2 are attached to the designated positions on the human body, the multiple electrode wires 2 are respectively inserted into the multiple elastic plates 3. Then close the two U-shaped frames 1, and insert the rectangular block 7 into the second rectangular groove. The inclined surface makes it easy for the locking block 5 to push the rectangular block 7 downward and compress the spring 6. When the locking block 5 is aligned with the locking groove, the spring 6 pushes the rectangular block 7 and makes the locking block 5 engage with the locking groove. This allows for quick organization and storage of multiple electrode wires 2, preventing multiple electrode wires 2 from getting tangled and knotted during use, thus improving the convenience of use.
