Technical Field

The invention relates to the technical field of medical treatment, in particular to the technical field of transcranial direct current stimulation (tDCS), and specifically relates to a system for realizing disease self-evaluation aiming at a portable head-wearing intelligent self-service transcranial direct current stimulator, a corresponding firmware processing method and a stimulator.

Background

Transcranial direct current stimulation (tDCS) is a non-invasive nerve regulation technology and comprises one or more cathodes and anode electrodes, after the electrodes are placed on the surface of a scalp, a stimulator outputs 1-2 mA weak direct current, and the current flows from the anode to the cathode to form a loop. Part of the current can be shunted by skin, skull and cerebrospinal fluid, part of the current can reach the brain parenchyma, and the stimulation of 2mA at the maximum for 30 minutes is safe and can change the cortical excitability and synaptic plasticity. Alterations in cortical excitability and prominent plasticity are also one of the pathophysiological mechanisms of many psychiatric disorders, and thus tDCS may ameliorate the symptoms of various psychiatric disorders, such as sleep disorders, depression, obsessive-compulsive disorders, anxiety disorders, and the like. In view of the limitations of traditional drug therapy and psychological therapy in the efficacy of psychiatric disorders, physical interventions including tDCS hold good promise in the field of psychiatric disorders. Common stimulation targets for tDCS include dorsolateral prefrontal lobe (DLPFC), orbitofrontal cortex (OFC), and the like. the tDCS has the advantages of safety, portability, wearability and low cost, but because the treatment period is usually more than 10 continuous days, and the time and labor cost are high, the portable and self-service tDCS is used for increasing the accessibility of tDCS treatment, reducing the time for going to and from a medical institution and facilitating more patients with mental diseases in need. Meanwhile, the pubic sensation of mental disease often causes patients to refuse to receive treatment, and if the attribute of 'medical equipment' of the appearance of the treatment equipment can be reduced, the acceptability of the treatment equipment can be improved.

The system for realizing self-evaluation of diseases by aiming at the portable head-wearing intelligent self-help transcranial direct current stimulator, the corresponding firmware processing method and the portable head-wearing intelligent self-help transcranial direct current stimulator have the following remarkable technical effects:

1. the use of the self-service and portable tDCS instrument is beneficial to improving the popularity and the acceptability of the tDCS, so that the wearing, the positioning, the mode selection and other operations of the cap type stimulator can be automatically completed by a patient in a home environment, and the time and the economic cost caused by repeatedly going to and fro to treat the disease by a medical institution are avoided.

2. According to the symptom self-evaluation (evaluation method with independent intellectual property rights) result of mobile phone end software or the psychological evaluation result of an independent input professional organization, different mental symptom stimulation modes are intelligently recommended, selected and switched, and tDCS treatment of various mental symptoms is integrated into one device, so that the application range of the tDCS is enlarged.

3. The device has a plurality of optimized stimulation modes built in the stimulator end based on a large amount of clinical research, and the stimulation modes can be updated irregularly according to the latest evidence-based research result, so that intelligent and self-service intervention is realized; meanwhile, the independent setting function at the mobile phone end is also reserved, and the psychiatric department professional is allowed to guide the use.

4. The head stimulator adopts a cap type design, so that the operation is convenient, the appearance is attractive, the 'sick pubic feeling' possibly brought by the traditional stimulator is reduced, and the head stimulator is more easily accepted by a user.

In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
