Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to an electromyography feedback electrical stimulator. Background Technology

[0002] Electromyographic feedback electrical stimulators are mainly used to treat and improve neuromuscular dysfunction. They stimulate peripheral nerves and muscles with low-frequency electrical pulses, causing muscle excitation and contraction, promoting nerve function regeneration, and improving muscle condition. This instrument can be used to treat muscle dysfunction caused by central and peripheral nerve damage, as well as problems such as delayed motor function development in children.

[0003] Traditional electromyography feedback electrical stimulators typically employ a three-dimensional design, resulting in a relatively large overall volume and heavy weight, which also causes inconvenience during transportation and carrying, leading to a poor user experience. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1: This utility model provides a myocardial feedback electrical stimulator, such as... Figures 1 to 6 As shown, the device includes a chassis 1, a bracket 2 fixedly mounted at the center of the top of the chassis 1, a storage box 3 fixedly fitted onto the outer surface of the bracket 2, a top plate 4 fixedly mounted on the top of the bracket 2, and an electrostimulation device body 5 mounted on the outer side of the top plate 4. In use, the operator applies conductive paste to the electrode surfaces of the electrostimulation device body 5, then fixes it to the skin of the patient's treatment area, connects the motor wires to the electrostimulation device body 5, and activates the device. The device then begins to collect electrical signals from the patient's muscles. All of the above are existing technologies and will not be repeated here; a mounting plate 6 is fixedly installed on the back of the electrical stimulator body 5, and sliders 7 are symmetrically fixedly installed on the outer surface of the mounting plate 6. A groove is opened inside the top plate 4 corresponding to the outer position of the slider 7. A locking block 8 is slidably installed inside the top plate 4. A locking groove is opened inside the two sliders 7 corresponding to the outer position of the bottom end of the locking block 8. During installation and use, the sliders 7 are slidably installed inside the top plate 4, so that the bottom end of the locking block 8 is engaged in the locking groove of the slider 7. A fixing shaft 9 is fixedly connected between the inner walls of the locking blocks 8. Figure 3 and Figure 6 As shown, a through groove is provided at the locking block 8, and the fixing shaft 9 is located inside the through groove. The connecting frame 11 can completely pass through the through groove. An auxiliary seat 10 is fixedly installed on the back of the top plate 4. The connecting frame 11 is rotatably connected to the outer side of the auxiliary seat 10. A spring 12 is fixedly installed at the bottom end of the connecting frame 11. The end of the spring 12 away from the connecting frame 11 is fixedly connected to the outer surface of the auxiliary seat 10. A slot is provided inside the connecting frame 11. The outer surface of the fixing shaft 9 is in contact with the inner wall of the slot of the connecting frame 11. By pressing down the tail end of the connecting frame 11, the spring 12 is compressed and deformed. When the connecting frame 11 is pressed, the connecting frame 1... 1. When the end of the connecting frame 11 with the slot moves upward, the outer surface of the fixed shaft 9 comes into contact with the inner wall of the slot. When the end of the slot of the connecting frame 11 moves upward, it drives the fixed shaft 9 to move upward. When the fixed shaft 9 moves, it drives the locking block 8 to slide upward, so that the bottom end of the locking block 8 disengages from the locking groove inside the slider 7. Thus, the slider 7 is no longer limited, and the mounting plate 6 and the electrical stimulator body 5 are pulled out and removed from the inside of the top plate 4 as a whole. This facilitates the disassembly of the electrical stimulator body 5 and makes it convenient for staff to separate the electrical stimulator body 5 from the bracket 2 for use. This meets the user's needs in complex environments and improves the practicality of the equipment.

[0023] like Figure 1 and Figure 5As shown, a sliding rod 13 is slidably installed inside the bracket 2. A connecting rope 14 is fixedly connected to the bottom end of the sliding rod 13. A counterweight 15 is fixedly connected to the end of the connecting rope 14 away from the sliding rod 13. The number of connecting ropes 14 and counterweights 15 corresponds one-to-one, and the counterweights 15 are all slidably installed inside the chassis 1. When using the device, the counterweights 15 are slid out from inside the chassis 1, so that the bottom end of the counterweights 15 contacts the ground, thereby increasing the contact area between the device and the ground and improving the stability of the device.

[0024] like Figure 4 and Figure 5 As shown, the top outer side of the slide bar 13 is rotatably sleeved with a limiting block 16. The inside of the bracket 2 is provided with a limiting notch 17 corresponding to the outer position of the limiting block 16. The limiting block 16 is engaged inside the limiting notch 17. At this time, the counterweights 15 inside the chassis 1 are all off the ground, so that the counterweights 15 are retracted into the inside of the chassis 1, making it convenient for the staff to move and operate the device.

[0025] Working principle: When in use, the operator presses down on the tail end of the connecting frame 11, causing the end of the connecting frame 11 with the slot to move upward. The outer surface of the fixed shaft 9 contacts the inner wall of the slot, causing the fixed shaft 9 to move upward as the end of the connecting frame 11 with the slot moves upward. When the fixed shaft 9 moves, it causes the locking block 8 to slide upward, causing the bottom end of the locking block 8 to disengage from the sliding groove position inside the top plate 4. Then, the electrostimulator body 5 and the mounting plate 6 are slidably installed inside the top plate 4. The connecting frame 11 is released, and the spring 12 is compressed, causing the tail end of the connecting frame 11 to move upward. This causes the annular end of the connecting frame 11 to slide downward, causing the bottom end of the locking block 8 to engage inside the slot of the slider 7. Thus, the electrostimulator body 5 and the mounting plate 6 are installed on the top of the bracket 2, which is convenient for operation and allows the user to quickly disassemble the electrostimulator body 5. It also allows the operator to separate the electrostimulator body 5 from the bracket 2 for use, meeting the flexible needs of the device in different scenarios and improving the practicality of the device.

[0026] When using this integrated device to treat a patient, rotating the limiting block 16 disengages it from the limiting notch 17, causing the counterweight 15 inside the chassis 1 to be no longer fixed. This allows the counterweight 15 to slide downwards under the influence of gravity, resulting in the bottom of the counterweight 15 contacting the ground. The upper part of the counterweight 15 is engaged inside the chassis 1, effectively increasing the contact area between the device and the ground and improving the stability of the three-dimensional equipment during use.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
