Simple and efficient carsickness prevention method and device

Abstract

The invention discloses a carsickness prevention method and device. High-pressure gas with variable frequency and pressure intensity can be generated in a running vehicle. In a dynamic system formed by the nose, the ears and the eyes of a carsickness person, and'airflow with variable frequency and pressure 'and'images seen by the eyes' in a vehicle, the variable high pressure or gas can enter or be conducted to the vestibule of the carsickness person through the ears or the nose, so that the vestibule directly or indirectly sends a false motion signal to the brain, and the false motion signal is transmitted to the brain of the carsickness person. And meanwhile, the eyes can generate a static signal and transmit the static signal to the brain, and the brain can carsickness after receiving a motion and static conflict signal. After the mask, the eyeshade and the earplugs are worn, the nose (mouth), the ears and the eyes of a carsickness person can be separated from the system to form a new independent system, so that variable high pressure or gas does not enter the middle ears through the nose and the ears, false motion signals generated by the vestibule and transmitted to the brain are avoided or reduced, and no static signals generated by the eyes and transmitted to the brain are generated; carsickness caused by the fact that the brain receives motion and static conflict signals is avoided or reduced.

Description

Technical Field

[0001] This invention relates to the field of motion sickness prevention technology, and in particular to an "efficient and simple method and apparatus for preventing motion sickness". Background Technology

[0002] When a person is inside a moving vehicle, their body is jolted and accelerated by the vehicle's movements. The vestibular system senses "motion," sending a signal to the brain that the person is "moving." However, if the person inside the vehicle also looks at stationary objects moving with the vehicle (such as a mobile phone or a book), the eyes send a "stationary" signal to the brain. This conflicting "motion" signal from the two senses can cause the brain to misinterpret and confuse the person, especially someone prone to motion sickness, leading to symptoms such as nausea, vomiting, dizziness, headache, vertigo, and fatigue. In addition, the vibrations of airflow with varying frequency and pressure can disrupt the body's balance regulation function, which is also a mechanism leading to motion sickness.

[0003] To date, there is no highly effective or particularly effective method or device to fundamentally prevent or solve motion sickness. Current technology— 1. The essential oil for relieving motion sickness published under CN115040625A is effective because it evaporates quickly in the respiratory tract. However, many people are allergic to certain elements of it, and it also contains toxins that people generally believe "all medicines have some degree of toxicity". 2. The patent CN202411066375.8, "A method and system for evaluating occupant motion sickness during intelligent chassis driving process", is not only complex, but also has four steps, each of which is extremely complex. The first step alone includes "collecting chassis motion information, calculating chassis roll angle motion sickness excitation index, chassis pitch angle motion sickness excitation index, chassis yaw angle motion sickness excitation index, and calculating frequency-weighted acceleration vibration total amount"; 3. Patent application CN202511233379.5, entitled "A Seat Air Blowing System, Seat Air Blowing System Control Method, Seat and Vehicle", uses a very complex inflation drive component and multi-way valve, air circuit component, etc., to adjust multiple outlets of the multi-way valve and change multiple air outlets of the air circuit component to control the air volume, so as to realize multi-channel air blowing, multi-blowing mode control, etc.

[0004] The first technology mentioned above causes allergies in some people and contains so-called "toxins." The latter two technologies are not only complex in structure, system, and method, but also very expensive. Summary of the Invention

[0005] Inside a moving car, especially at high speeds, highly mobile gases are generated. These gases, upon colliding with other objects or gases, further increase their pressure. The cold or hot air emitted by the car's air conditioning system exacerbates this pressure increase, resulting in "high-pressure" gases with fluctuating frequency and pressure inside a moving vehicle. These fluctuating pressures, and even the gas itself, can enter the middle ear through two pathways: first, from the outer ear; and second, first through the nasal cavity (or mouth) into the Eustachian tube in the nasopharynx (an accessory structure of the middle ear), before finally entering the middle ear (causing abnormal pressure in the middle ear, etc.). The changing pressure and gas enter the middle ear and then enter or are conducted to the semicircular canals, otolith organs, and otoliths of the vestibule, causing the vestibule to send or aggravate false motion signals and changing frequency and pressure stimulation signals to the brain. At the same time, if the person in the car looks at stationary objects in the car (such as mobile phones, books, etc.), the eyes will transmit a "stationary" signal to the brain. The contradictory and conflicting motion and stillness signals from these two senses, as well as the changing frequency and pressure stimulation signals, can cause or aggravate motion sickness symptoms in people who are prone to motion sickness (in fact, everyone can get motion sickness, but some people can supposedly resist it, and the symptoms of motion sickness are extremely minor or short-lived, passing in an instant without being felt).

[0006] If the "high-pressure" airflow with its varying frequency and pressure causes the Eustachian tube to be unable to balance the middle ear pressure in time, it can lead to ear fullness, ear pressure, or even mild pain. This "ear discomfort signal" will be superimposed on the original "sensory conflict signal," further aggravating the brain's confusion and making motion sickness symptoms more pronounced. (This symptom proves that the changing pressure of the "high-pressure gas," and the gas itself, can enter the middle ear through the Eustachian tube in the nasopharynx, as well as the nasal cavity and oral cavity; otherwise, the middle ear could not experience a pressure imbalance.) The reason why motion sickness or worsening motion sickness occurs is mainly because the nasal cavity (oral cavity), ears, eyes, and the "airflow with changing frequency and pressure" and "images seen by the eyes" in the carriage are in a dynamic system. They influence each other, especially the latter two, which affect the former three.

[0007] Therefore, using the following three methods not only reduces the sensitivity of the human sensory system to the external environment, but also separates the nasal cavity (oral cavity), ears, and eyes from the dynamic system formed by the "frequency and pressure changes in airflow" and "images seen by the eyes" inside the car. This separates the nasal cavity (oral cavity), ears, and eyes from the "frequency and pressure changes in airflow" and "images seen by the eyes" into an "independent" system that the human body already possesses (in calm air) after the above organs are "closed". This prevents the pressure and gas of the high-pressure airflow with changing frequency and pressure inside the car from stimulating or impacting the facial nerves and eyes, and prevents or makes it difficult for them to enter the middle ear through the nasal cavity (oral cavity) and outer ear. This prevents or reduces the transmission of "false motion signals generated by the vestibule" and "stimulation signals of changing frequency and pressure" to the brain. Most importantly, it also avoids the transmission of static signals generated by the visual system to the brain, which could cause misjudgment or confusion in the brain, thus preventing or alleviating motion sickness symptoms.

[0008] The three methods are— 1. Covering the face of a person inside a moving vehicle with a semi-permeable cover (mainly to cover the nasal cavity and oral cavity) not only reduces the sensitivity of the facial sensory system to the external environment, but also prevents or reduces the pressure and gas of high-pressure airflow with varying frequency and pressure from entering the nasal cavity (or oral cavity) and then entering or being conducted through the Eustachian tube in the nasopharynx to the semicircular canals, otolith organs, and otoliths in the vestibule, thereby preventing or reducing or weakening the transmission of "false motion signals generated by the vestibule" and "stimulation signals with varying frequency and pressure" to the brain. 2. Blocking a person's ears inside a moving car not only reduces the sensitivity of the facial and auditory systems to the external environment, but also prevents or reduces the pressure and gas of high-pressure airflow with changing frequency and pressure from entering the middle ear from the outer ear, and then entering or being conducted to the semicircular canals, otolith organs, and otoliths of the vestibule, thereby preventing or reducing the transmission of "false motion signals generated by the vestibule" and "stimulation signals with changing frequency and pressure" to the brain. 3. Covering the eyes of people inside a moving car not only reduces the sensitivity of the eye system to the external environment, but also prevents the eyes from sending signals of stationary objects inside the car, such as mobile phones and books, to the brain.

[0009] In summary, the method of this invention is to isolate the nasal cavity (oral cavity), ears, and eyes—which are actually part of a dynamic system—from the dynamic system formed by the "frequency and pressure changing airflow" and the "images seen by the eyes" within a moving vehicle, making them an independent system (in calm air) inherent in the individual. This prevents the pressure and gas of the high-pressure airflow with changing frequency and pressure from entering the middle ear and then entering or being conducted to the vestibule (semicircular canals, otolith organs, and otoliths), nor from passing through the nasal cavity (or oral cavity) and the Eustachian tubes in the nasopharynx to enter or be conducted to the vestibule (semicircular canals, otolith organs, and otoliths), thereby avoiding or reducing— The pressure and gas of high-pressure airflow with varying frequency and pressure directly or indirectly affect the vestibular system, causing it to send false and erroneous motion signals to the brain; the eyes generate stationary signals that are transmitted to the brain; the brain simultaneously receives conflicting signals of motion and stillness; and the brain receives stimulating signals of varying frequency and pressure.

[0010] This can prevent or alleviate motion sickness.

[0011] II. The device of the present invention The simple and efficient motion sickness prevention device manufactured according to the method of the present invention includes: a mask, earplugs, and eye mask.

[0012] Masks can significantly reduce airflow, which not only reduces the sensitivity of the mouth, nose, and facial nerves to the external environment, but also prevents or reduces the pressure and gas of high-pressure airflow with changes in frequency and pressure from entering the nasal cavity (or oral cavity) and then entering or being conducted through the Eustachian tube in the nasopharynx to the semicircular canals, otolith organs, and otoliths in the vestibule. This prevents or reduces or weakens the transmission of "false motion signals generated by the vestibule" and "stimulation signals with changing frequency and pressure" to the brain. Earplugs not only reduce the sensitivity of the human facial ear system to the external environment, but also prevent or reduce the pressure and gas of high-pressure airflow with changes in frequency and pressure from entering the middle ear from the outer ear, and then entering or being conducted to the semicircular canals, otolith organs, and otoliths of the vestibule, thereby preventing or reducing the transmission of "false motion signals generated by the vestibule" and "stimulation signals with changing frequency and pressure" to the brain. Eye masks not only reduce the sensitivity of the eye system to the external environment, but also prevent or reduce the pressure and gas of high-pressure airflow with frequency and pressure changes generated inside a moving vehicle from stimulating and impacting the eyes and facial nerves around the eyes. In particular, they prevent the eyes from sending signals of the stationary state of objects inside the vehicle, such as mobile phones and books, to the brain.

[0013] Wearing a mask, earplugs, and goggles while in a moving vehicle can prevent or reduce motion sickness symptoms.

[0014] It can manufacture goggles, earplugs, masks or earplugs, masks or earplugs, goggles or goggles, masks connected together in one piece for people to wear or store (swimming goggles are sometimes connected to earplugs).

[0015] The earplug tip (also called the earplug head) of the earplug can be relatively short, about 0.5 to 1 cm long. This prevents the earplug tip from being inserted too deeply into the ear canal, which would reduce the amount of still air in the external auditory canal. This reduces the impact of the high-pressure gas with varying frequency and pressure inside the car on the vestibule, thereby preventing or reducing the transmission of false motion signals and stimulation signals of varying frequency and pressure from the vestibule to the brain. It also avoids discomfort caused by the earplug tip being inserted too deeply into the ear canal.

[0016] The eye mask can be black, which can effectively block out static or moving scenes from the eyes and make it easier for people to sleep and rest in the vehicle.

[0017] The ventilation resistance of a mask (i.e., the obstruction effect of fluid flow. The flow driving force or flow resistance of a fluid is expressed by pressure difference) can be greater than that of an ordinary mask, i.e., more than 49 Pascals, in order to reduce the fluidity of the airflow and control the pressure and gas of high-pressure gas that changes frequency and pressure in the vehicle, and the ability of the gas to enter or be conducted through the nasal cavity (or mouth) to the vestibule.

[0018] The inventor also suffers from motion sickness. After inventing this invention, he specifically tested it on himself and found that he no longer gets motion sickness; the effect was extremely good.
