Description

Earbuds with near-infrared radiation

The present invention relates to an earbud having a near-infrared irradiation unit.

Traumatic brain injury (TBI), stroke, multiple sclerosis (MS), schizophrenia, autism, insomnia, post-traumatic stress disorder (PTSD), dementia and Alzheimer's disease (Alzheimer's), Parkinson's disease (Parkinson's) And in the case of the treatment using drugs for chronic brain diseases such as a number of other neurological conditions and disorders, there are many side effects and disadvantages.

One of the alternative therapies for this, brain stimulation, has been in use for some time, based on the fact that the nervous system responds to these techniques in a practical way. Many of these technologies are based on electromagnetic shock.

Brain stimulation can be broadly divided into invasive brain stimulation and non-invasive brain stimulation. As an invasive brain stimulation technique, electric stimulation through implanted eletrodes can be exemplified, and it is a method of controlling abnormal neural circuits by inserting electrodes into the brain base and applying electrical stimulation. In the case of electrode insertion brain stimulation, deep brain (thalamic, basal ganglia, hypothalamus ganglia of the brain) can be stimulated. Therefore, it is used as a treatment method to improve symptoms of abnormal motor diseases such as Parkinson's disease, essential tremors, and dystonia. There is a disadvantage in that it requires surgery to insert electrodes and stimulation generators into the body.

Non-invasive brain stimulation techniques include Transcranial Magnetic Stimulation (TMS) and Transcranial Direct-Current Stimulation (TDCS). TMS and TDCS technologies have low penetrating power and cannot stimulate the center of the brain.

In addition, ultrasound brain stimulation (Transcranial Ultrasound Stimulation) and near-infrared stimulation (Near-Infrared Stimulation, NIS) are safe compared to invasive brain stimulation methods, and, unlike TMS and TDCS, stimulation to the deep brain is possible.

In near-infrared (NIR), mitochondrial CCO enzyme (Cytochrome C Oxidase) absorbs near-infrared rays and increases the production of ATP (Adenosine triphosphate; the main energy source in the human body). In addition, it stimulates vascular endothelial cells and red blood cells to increase production of nitric oxide (NO, Nitric Oxide; prevents blood clotting, relaxes smooth muscles). When ATP increases, it promotes cell metabolism and energy to regenerate cells and prevent cell death. When NO increases in the body, blood vessels expand, blood flow increases, and the amount of oxygen supplied to the brain increases, thereby improving memory and cognitive functions.

These near-infrared rays can pass through the skull and penetrate the brain. It can penetrate through the skull and scalp to an average depth of 23.6mm (depth from the scalp) (when shaved). However, the near-infrared wavelength has a blind spot that the transmittance to the hair is low, and more than 85% of the near-infrared energy irradiated on the scalp is absorbed by the scalp and skull.

One side of the housing 100 is provided with a conduit 120 protruding into an external space so as to be easily inserted into the user's ear canal. An opening formed at one end of the conduit 120 communicates the receiving space of the housing 100 and the external space, and an acoustic discharge port 130 is formed at the opening of the conduit 120. The sound generated by the sound output device 200 is discharged to the external space through the sound discharge port 130 through the conduit 120 and transmitted to the user's ear.

On the other hand, a near-infrared emission port 140 through which near-infrared rays are emitted is formed at the opening of the conduit 120. A window (not shown) made of a near infrared ray transmissive material may be formed in the near infrared ray emission port 140.

A partition wall 104 is formed between the accommodation space (including the opening of the conduit 120) and the outer space, and the partition wall 104 is a near-infrared irradiation path (or area) including the irradiation unit 300 or the irradiation direction and sound The sound output path (or region) or the output direction in which the output device 200 is included is physically divided into at least two or more regions. The partition wall 104 extends from the accommodation space to the opening of the conduit 120, an acoustic emission port 130 is formed in one area partitioned by the partition wall 104, and a near-infrared emission port 140 in the other area. Is formed.

The irradiation unit 300 and the sound output device 200 for emitting near-infrared rays may be installed on the bracket 102 provided in the housing 100. As shown in Figure 2, the partition wall 104 is connected to at least a portion of the bracket 102, so that the structure is rigid.

As described above, in the case of the earbuds partitioned by the partition wall 104 and having a near-infrared irradiation direction parallel or substantially parallel to the acoustic emission direction, irradiation by installing the irradiation unit 300 in the pipe 120 inserted into the ear canal There is an effect that the near-infrared rays can stimulate the deep part of the brain by avoiding the two bones with a high absorption rate of near-infrared rays.

In addition, at least one irradiating

portion

310a, 310b, 310c, and 310d for irradiating near-infrared rays may be formed on an outer surface of the housing 100 other than the inside of the pipe 120. The irradiation direction of the near-infrared rays of each of the irradiation units 310a to 310d is the same as the irradiation direction of the irradiation unit 300, or by forming a right angle or an acute angle with respect to the irradiation direction of the irradiation unit 300, generated by each of the irradiation units 310a to 310d The generated near-infrared rays are irradiated to the user's ear wheels.

These irradiation units 310a to 310d may stimulate the user's cerebral cortex, deep brain, facial nerve, or vagus nerve when the earbuds are worn.

Vagus verve stimulation is also used to treat depression, and other mental disorders such as dementia, schizophrenia, and autism have also been tried.

When stimulating the cerebral cortex, it is effective in treating depression, obsessive-compulsive disorder, and chronic pain, and improving memory and cognition through increased blood flow.

In particular, the vagus nerve, the cerebral cortex, and the facial nerve are stimulated according to the installation positions of the

irradiation units

310a, 310b, 310c, and 310d. At this time, it is preferable that the

irradiation units

310a, 310b, 310c, and 310d are located in portions that do not come into contact with cartilage to increase the transmission rate of near-infrared rays.

In addition, when a pair of earbuds 100 are respectively inserted and seated in both ears of a user and worn to be worn, the irradiated near-infrared rays may stimulate the deep brain. Since the near-infrared rays are irradiated through the empty space of the skull (the ear canal), it has the advantage of being able to stimulate deeper places than when stimulating through the scalp. In addition, near-infrared stimulation increases blood flow and oxygen supply to the brain, thereby improving memory and cognitive function. The advantage of irradiating near-infrared rays from both earbuds is that intensive light stimulation (focusing) in the deep part of the brain is possible.
