  • the causes of motion sickness can be explained in various ways, but there is an opinion that explains the difference between vision and other senses as a self-defense phenomenon that occurs when the human body judges it to be a danger signal. According to this opinion, in situations where motion sickness is likely, the autonomic nervous system determines that a problem has occurred in the body and sharpens the senses to find the cause. In particular, the sense of smell is greatly affected because, from an evolutionary perspective, it is said that the need to increase olfactory sensitivity remains when the cause of physical abnormalities is spoiled food or toxic food such as poisonous mushrooms.
  • Prevention of motion sickness is effective, and representative treatments for prevention include antihistamines, anticholinergics (parasympathetic nerve blockers), antispasmodics (anticonvulsants), and sympathomimetics.
  • antihistamines are first-generation antihistamines such as meclizine, dimenhydrinate, and chlorpheniramine, and are mainly used in combination with pyridoxine or caffeine.

  • Drugs such as antihistamines and scopolamine have anticholinergic side effects such as blurred vision, dry mouth, constipation, and urinary retention. In some cases, the side effects can make motion sickness worse. In the case of children, pregnant women, and patients, extra caution is required when using motion sickness medication, making it difficult to use motion sickness medication on a daily basis without risk.

  • Motion sickness is a phenomenon that occurs when the human body judges the difference between vision and other senses as a danger signal.
  • the autonomic nervous system which determines that there is a problem with the body, tends to sensitize other senses to find the cause, and the sense of smell is especially greatly affected. This appears to be because it is thought to be an effect of toxic food such as spoiled food or poisonous mushrooms.
  • Symptoms vary slightly from person to person, but usually include dizziness, headache, and nausea caused by low blood pressure. Sometimes you break out in a cold sweat, and often burp or yawn for no reason. The sense of smell is strengthened, the stomach weakens, and you may feel drowsy. In particular, when nausea becomes severe, sour fluid comes out of the mouth and eventually causes vomiting. This spreads to the surrounding area, causing other people who are also suffering from motion sickness to vomit as well. It may cause shock and fear.
  • Symptoms persist for quite a long time even after getting off the vehicle. It lasts at least 10 minutes and on average several hours. In severe cases, it may last more than 2 days.
  • vagus nerve connected to the stomach is overexcited, producing too much acetylcholine and histamine, and when these neurotransmitters stimulate the vestibular system again, it stimulates the vomiting center in the medulla oblongata. .
  • the factors that cause motion sickness may be diverse, but motion sickness can be understood as a result of a disruption in the harmony and balance of the autonomic nervous system.
  • electrical stimulation of the vagus nerve is provided to alleviate and prevent problems with the autonomic nervous system, thereby preventing motion sickness symptoms from occurring.
  • the vagus nerve is one of the cranial nerves and corresponds to the 10th cranial nerve.
  • the vagus nerve emerges from the brain and is distributed throughout the face, chest, and abdomen. It is a mixed nerve containing parasympathetic nerve fibers and is involved in the regulation of the parasympathetic nerves that act on the heart, lungs, and digestive tract. It is the longest and most complex of the 12 pairs of cranial nerves, and contains both sensory and motor nerve fibers. It is known that electrical stimulation of the vagus nerve can improve cerebral plasticity and increase neural activity, and can especially regulate the activity of the parasympathetic nerve among the activities of the autonomic nervous system.
  • the parasympathetic nerve is suppressed and the sympathetic nerve is activated. Therefore, similar to the mechanism of existing motion sickness drugs, motion sickness is alleviated by the action of parasympathetic nerve blockers (anticholinergics), antispasmodics (anticonvulsants), and sympathomimetics.

Abstract

L'invention concerne un dispositif qui transmet une stimulation de la forme d'un écouteur porté sur l'oreille d'un porteur pour prévenir et atténuer le mal des transports d'un utilisateur. Le dispositif comprend une pluralité d'électrodes qui sont en contact avec différentes parties parmi le nerf vague du porteur et transmettent une stimulation électrique, et un processeur pour commander à la pluralité d'électrodes de réguler la fréquence et/ou l'intensité de la stimulation. Le dispositif comprend un premier ensemble destiné à venir en contact avec l'oreille gauche d'un porteur et un second ensemble destiné à venir en contact avec l'oreille droite du porteur, le même nombre d'une pluralité d'électrodes étant inclus dans le premier ensemble et le second ensemble, respectivement, dans une structure symétrique.
