Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a portable electrical stimulator. Background Technology

[0002] EEG-based bionic electrical stimulation, as an important neurorehabilitation treatment, has been widely used in the treatment and rehabilitation of brain diseases. Currently, EEG-based bionic electrical stimulation devices on the market mainly suffer from the following problems:

[0003] 1. Poor portability: Most existing equipment is desktop-style, making it bulky. For example, the HB520D model measures 420mm × 360mm × 232mm and needs to be fixed in the treatment room or ward, making it difficult to move flexibly to the bedside or emergency room. Although some mobile devices are equipped with wheels, their overall weight exceeds 10kg, resulting in low operating efficiency.

[0004] 2. Dependence on power supply and wiring: Most devices require an external 220V power supply and are equipped with complex cables to connect the electrodes. For example, the electrode wires are up to 1850mm long, which leads to messy wiring in the treatment area, poses a tripping risk, and cannot be used in places without a fixed power supply.

[0005] 3. Limited treatment scenarios: Traditional equipment is only suitable for fixed treatment environments and cannot meet the needs of home rehabilitation, community medical care, or emergency scenarios. For example, patients in the recovery period of cerebral hemorrhage need long-term treatment, but frequent trips to the hospital are costly.

[0006] 4. High maintenance costs: Large mainframes require regular calibration and maintenance, which increases the burden of equipment operation and maintenance.

[0007] Therefore, developing a highly integrated, portable electrical stimulator that can be used in various scenarios has significant clinical implications and market value. Utility Model Content

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a top view of the entire utility model. Figure 3This is a schematic diagram of the overall internal structure of this utility model.

[0022] This utility model provides a portable electrical stimulator, including a convenient stimulation component. The component comprises a plastic lower shell 6, a battery 9, a control circuit board 10, a transformer 11, a plastic upper shell 1, a protective film 2, a panel button 3, a display screen 4, a power button 5, magnetic contacts 7, and spring contacts 8. This solution addresses the problems of poor portability, reliance on power and wiring, limited treatment scenarios, and high maintenance costs in existing technologies. Specifically, when the power is on, pressing the power button 5 allows the battery 9 to power the device. Current is distributed to various functional modules via the control circuit board 10, and the transformer 11 regulates the voltage to provide adaptation for different functions. When setting the power parameters, the user selects the desired treatment mode (such as cerebellar parietal nucleus electrical stimulation, magnetic therapy, or limb electrical stimulation) on the display screen 4 via the panel button 3, and sets the corresponding treatment parameters, such as current intensity, frequency, and treatment time. For example, when selecting the cerebellar parietal nucleus electrical stimulation mode, the current intensity can be set to 2mA and the treatment time to 20 minutes. For electrode connection, the device is connected to the external electrode pads using the magnetic contact 7 and the spring contact 8. The magnetic design facilitates quick positioning and adsorption, while the spring contact ensures a tight connection and conductivity, allowing the electrode pads to stably transmit current to the treatment area. To begin treatment, after setting the parameters and connecting the electrodes, press the panel button again. Button 3 initiates treatment. Taking magnetotherapy as an example, the control circuit board 10 controls the transformer 11 to generate a specific magnetic field, which acts on the human body through electrode pads, regulating the body's biomagnetic field and generating induced microcurrents to achieve auxiliary therapeutic effects such as reducing swelling and relieving pain. During limb electrical stimulation, the control circuit board 10 outputs pulsed current, which stimulates the nerves controlling the muscles through the electrode pads, causing muscle contraction. During treatment, the display screen 4 displays treatment parameters and remaining time in real time for user monitoring. When treatment ends, the device automatically stops working after the preset treatment time is reached. The user disconnects the electrode pads from the device and presses the power button 5 again to turn off the device, completing one treatment cycle. In a home rehabilitation setting, patients do not need to go to the hospital. This portable electrical stimulator can be used for treatment at any time in the hospital. Its compact size (a compact shell composed of the upper plastic shell 1 and the lower plastic shell 6) and lightweight design make it convenient for patients to move and use in different spaces such as bedrooms and living rooms. The built-in battery 9 supports long-term battery life, eliminating dependence on external power sources. Even if there is a power outage at home, treatment will not be affected. In community healthcare scenarios, when medical staff carry this device to provide services to multiple patients, the convenient magnetic contact 7 and spring contact 8 connection method allows for quick replacement of electrode pads, improving work efficiency. The simple operation interface of the panel button 3 and the display screen 4 makes it easy for medical staff to quickly set treatment parameters and provide personalized treatment for different patients.

[0023] In this specific embodiment, the battery 9 is detachably connected to the lower plastic shell 6 and is located inside the lower plastic shell 6. The transformer 11 is fixedly connected to the lower plastic shell 6 and is located inside the lower plastic shell 6, with the transformer 11 disposed on one side of the battery 9.

[0025] Secondly, the panel button 3 is detachably connected to the film 2 and is located above the film 2, and the panel button 3 is perpendicular to the film 2. The display screen 4 is fixedly connected to the film 2 and is located on one side above the film 2, and the display screen 4 is located on one side of the panel button 3.

[0026] Meanwhile, one end of the power button 5 passes through the lower plastic shell 6 and is detachably connected to the battery 9, and is located on one side of the battery 9. The other end of the power button 5 is located on one side of the lower plastic shell 6, and the power button 5 is perpendicular to the lower plastic shell 6.

[0027] In addition, the magnetic contact 7 is fixedly connected to the lower plastic shell 6 and is located below the lower plastic shell 6. The spring contact 8 is fixedly connected to the lower plastic shell 6 and is located at the lower center of the lower plastic shell 6. The spring contact 8 is located on one side of the magnetic contact 7.

[0028] When using this invention, when the power is turned on, the user presses the power button 5, the battery 9 supplies power to the device, and the current is distributed to each functional module via the control circuit board 10. The transformer 11 regulates the voltage to provide suitable power for different functions. When setting parameters, the user selects the desired treatment mode (such as cerebellar parietal nucleus electrical stimulation, magnetic therapy, or limb electrical stimulation) on the display screen 4 via the panel button 3, and sets the corresponding treatment parameters, such as current intensity, frequency, and treatment time. For example, when selecting the cerebellar parietal nucleus electrical stimulation mode, the current intensity can be set to 2mA, and the treatment time can be set to... The treatment lasts for 20 minutes. During electrode connection, the magnetic contact 7 and spring contact 8 are used to connect the device to the external electrode pads. The magnetic design facilitates quick positioning and adhesion, while the spring contact ensures a tight connection and conductivity, allowing the electrode pads to stably transmit current to the treatment area. To begin treatment, after parameter settings and electrode connection are complete, press the panel button 3 again to start the treatment.
