Description

Technical Field

[0001] The present invention relates to the technical field of electrical stimulation for depression treatment, and in particular to an electrical stimulation system for depression treatment and a control method thereof. Background Art

[0002] Depression, also known as depressive disorder, is a common psychiatric illness characterized by overt, persistent depression, which may be accompanied by cognitive impairment and somatic symptoms. Current treatments for depression primarily include medication, psychotherapy, combined therapy, and physical therapy. Medication for depression can generally be divided into three phases: acute treatment, ongoing treatment, and maintenance therapy. Medication can improve symptoms in 60% to 70% of acute depressive episodes, with similar efficacy but varying side effects. However, it is only suitable for patients after the acute phase, particularly those in remission. Regarding combined therapy, there are numerous reports on combining psychotherapy and medication, which, by combining the advantages of each, is more effective than single medication. In recent years, several studies have demonstrated the effectiveness of transcranial direct current stimulation (tDCS) for the treatment of depression. This noninvasive neurostimulation technique uses small electrodes to deliver a low-voltage electrical current to specific brain regions, modulating cortical excitability and inducing changes in brain function. Existing empirical research demonstrates that tDCS is highly effective in treating depression, offering new hope for patient recovery and making it a highly promising therapeutic approach.

[0003] However, tDCS treatment of depression suffers from poor spatial positioning accuracy, making it difficult to effectively determine the electrode pad coverage area. This can lead to activation of the target brain region while also stimulating activity in other brain regions, potentially causing adverse reactions in patients with depression. To address this, we propose an electrical stimulation system and control method for depression treatment. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the prior art and to propose an electrical stimulation system for treating depression and a control method thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An electrical stimulation system for treating depression includes a nerve stimulation device, a positioning device, and an electrical stimulation output device, wherein the electrical stimulation output device is in contact with the center of the top of the head skin by binding;

[0007] The nerve stimulation device includes a pulse generator, which transmits the output electrical stimulation signal to the skin through the electrical stimulation output device, thereby forming electrical stimulation on the skin surface and acting on the brain nerves;

[0008] The positioning device includes a rotating seat and an angle plate. The electrical stimulation output device changes its angle through the rotating seat. At the same time, the rotation angle of each electrical stimulation output device is recorded and compared according to the angle plate. Finally, the electrical stimulation output position is determined according to the specific position of each adsorption lock, forming a precise determination of the electrical stimulation output area.

[0009] The electrical stimulation output device is bound to the center of the patient's head through a positioning device to change the angle, and by further changing the coverage area of ​​the electrical stimulation output device on the top of the head, precise adjustment can be achieved to activate the target brain area.

[0010] The area of ​​the electrode sheet on the electrical stimulation output device is set to 16 cm 3 .

[0011] Preferably, the neurostimulation device also includes a control unit and a power supply device. The control unit and the power supply device are electrically connected to the pulse generator. The power supply device supplies power to the pulse generator. At the same time, the pulse generator transmits the electrical stimulation signal emitted by the neurostimulation device to the electrode through a wire. After the electrode contacts the patient's head skin, the electrical stimulation signal is transmitted to the human body.

[0012] Preferably, the electrical stimulation output device includes an insulating sheet and a conductive sheet. The insulating sheet is composed of a non-woven fabric material and an isolation film. When in use, the isolation film is torn off to complete the adhesion of the non-woven fabric material to the skin on the top of the head.

[0013] Preferably, the electrical stimulation output devices are evenly distributed, and the surgical electrical stimulation output devices include at least two electrodes, and the electrical stimulation signal can be transmitted through one of the electrodes.

[0014] Preferably, the control unit includes a single-chip microcomputer control unit and a signal amplitude control unit. The single-chip microcomputer control unit generates a digital electrical stimulation signal and transmits the signal to the signal amplitude control unit for amplitude adjustment, and then transmits the signal to the pulse generator.

[0015] Preferably, the positioning device also includes a strap and a fixing strap, which are cross-stacked and arranged. The fixing strap is pivotally connected to the strap through a rotating seat, and the relative rotation angle between the strap and the fixing strap can be clearly recorded after the strap is rotated.

[0016] Preferably, the free ends of the fixing belts are embedded with evenly distributed adsorption lock buckles, and the relatively aligned fixing belts are adsorbed and fixed by the adsorption lock buckles.

[0017] A method for controlling an electrical stimulation system for treating depression comprises the following steps:

[0018] S1: First, calm the patient's emotions, then have the patient sit on the treatment chair. The chair's wrapping keeps the patient's body relaxed and head still, and removes any objects that may interfere with the electrical stimulation signal output.

[0019] S2: Set the parameters of the nerve stimulation device, fix the electrical stimulation output device on the patient's head skin, and adjust the fixed position according to the positioning device;

[0020] S3: Specifically, the angle disc and angle line on the positioning device are used to adjust the direction of the fixing belt, thereby determining the rotation angle of each electrical stimulation output device. After recording, the fixing belt is fixed using the adsorption lock, thereby determining the electrical stimulation output area;

[0021] S4: Each treatment time is controlled within 15 minutes, and 36 stimulations per minute;

[0022] S5: After the treatment is completed, the insulation sheet is disinfected so that it can be used again on the same patient next time.

[0023] The present invention proposes an electrical stimulation system for depression treatment and a control method thereof, which has the following beneficial effects:

[0024] The accuracy of spatial positioning is better, and it can effectively determine the coverage area of ​​the electrode plate, so as to achieve the purpose of activating the target brain area without driving the activity of other brain areas. BRIEF DESCRIPTION OF THE DRAWINGS
