Description

Intelligent eye physiotherapy equipment with electroencephalogram feedback

Technical Field

The invention relates to the technical field of beauty physiotherapy electronic equipment, in particular to an electroencephalogram feedback intelligent eye physiotherapy instrument.

Background

The massage is based on the theory of viscera and meridians of traditional Chinese medicine, and combines the anatomical and pathological diagnosis of western medicine, and acts on specific parts of the body surface by specific manipulations to regulate the physiological and pathological conditions of the body, and belongs to physical physiotherapy methods in nature classification; the electric massage is to use electric energy to drive the power device to make the massage head vibrate, thereby achieving the purpose of massage. Acupuncture is a general term of acupuncture and moxibustion, and acupuncture means that an acupuncture tool is inserted into a human body according to a method, and various methods of waking up the needle are used for stimulating specific parts of the human body so as to achieve the effect of physical therapy; the electric acupuncture does not penetrate into the body, and the skin patch type pulse therapy is used, although the effect on deep muscles is not satisfactory, the electric acupuncture has an especially obvious effect on superficial muscles, and the problems of wound, complexity and the like of the traditional acupuncture can be definitely solved. The electric acupuncture and massage can relax muscles and tendons, promote blood circulation, and relieve fatigue, and can be used for adjuvant treatment of chronic diseases.

Currently, most of eye physiotherapy instruments studied adopt an optical principle or a hot compress principle, or only have a single electric massage or electric acupuncture physiotherapy function, the two are not combined, the effect cannot be reflected through visual data, and the physiotherapy effect is unsatisfactory.

On the basis of the existing medical studies, and prior studies on tolerance, it is known that: 1) the receptors are each suitable for stimulation; (2) the receptor has a transduction function; (3) the receptors have the ability to encode the quality and quantity of stimulation, as well as other attributes; (4) the above characteristics indicate that the sensors have a modulation function.

The adaptation phenomenon that the receptor enters the chamber of the cheese and does not smell the fragrance for a long time refers to the phenomenon that the sensitivity of the receptor changes under the continuous action of the same stimulus. In general, the sensitivity is reduced by the sustained action of strong stimulation, and the sensitivity is increased by the sustained action of weak stimulation.

The resistance is called a phenomenon in which the acupuncture effect is reduced when the human body is subjected to long-term or repeated acupuncture stimulation. At present, the tolerance mainly stays in the aspects of subjective feeling and curative effect response of patients, and the verification of human body scientific data is lacked

"no disease but first acupuncture is inverse", and the theory that acupuncture therapy can treat 'no disease' is proposed in the traditional Chinese medicine as early as the Ming dynasty, and the ancient famous texts on acupuncture health care such as acupuncture key and massage ten methods, urgent gold key and acupuncture Dacheng provide assistant evidence for the traditional Chinese medicine, but lack scientific assistant evidence of modern technology.

In years of previous researches, it is found that under the condition that a human body is in a brain fatigue state, the power spectral densities of waves at a low frequency range of 0.5-3Hz and theta waves at 4-7Hz are enhanced and greatly changed, and the power spectral densities of beta waves at a high frequency range of 8-13Hz alpha waves and beta waves at 14-30Hz are reduced and slightly changed. In order to overcome brain fatigue, magnetic stimulation is applied to a human body, the power spectral density of the electroencephalogram signals in a low frequency band is found to be reduced and greatly changed, and the power spectral density of the electroencephalogram signals in a high frequency band is found to be increased and slightly changed. Therefore, the power spectral density change generated when the electric acupuncture tolerance is generated is similar to the electric acupuncture tolerance, the power spectral density change is taken as an important basis for identifying the tolerance of the instrument, and a large number of experiments are carried out to verify the correctness of the instrument.

In view of the above problems, the following solutions are proposed: the invention reads and analyzes the tolerance of human body to electric pulse and external physical massage stimulation, adjusts the physical therapy mode of the physical therapy instrument and achieves the novel physical therapy apparatus which improves the treatment effect of the comprehensive physical therapy instrument. Its aim at combines together traditional electric acupuncture appearance and massage appearance, solves traditional physiotherapy equipment and can not intelligent regulation pulse stimulation and easily makes the problem that the human body produced the tolerance, reduces complicated artifical judgement, simplifies operation flow, improves the physiotherapy curative effect.

The wires are connected to corresponding ports of the electroencephalogram acquisition chip through an electroencephalogram acquisition bus integrating four connecting wires.

It should be particularly noted that, after the theoretical research of the prior period, in order to improve the portability and accuracy of the invention, an optimal position for acquiring brain electricity is especially found, as shown in FP2 in fig. 6.

The brain electricity collecting function electrode is placed at the position of the international lead standard FP2 according to the above, and comprises a dry electrode 6 and an attached shielding layer. The electroencephalogram acquisition ear clip 10 is clipped at the left earlobe and is used as an electrode with a body relatively zero potential, the electroencephalogram signals acquired by the electroencephalogram acquisition part are potential differences between the FP2 conduction part and the left earlobe, and the shielding layers can effectively shield the interference of the outside and other signals of the body.
