Description

Device for treating the nasal cavity by light irradiation}

The present invention relates to a device that directly irradiates irradiated light to the endonasal cavity. More specifically, the present invention relates to an endonasal light that can treat inflammation and quickly restore the area damaged by inflammation to its original state by directly irradiating irradiated light energy to the endonasal cavity. It's about research devices.

In general, LED stands for light emitting diode and is a semiconductor that emits light when an electric current flows through it. These LEDs can not only emit all types of light, including ultraviolet rays, visible rays, and infrared rays, but can also control output and color, so they are widely used as light sources for lighting or medical devices.

The light generated from LED, which is a light source, has low energy and can control the light of the desired wavelength, so it has few side effects on the human body and does not cause damage to other body tissues. Therefore, the U.S. Food and Drug Administration (FDA) regulates the use of LED light wavelengths in the visible and near-infrared regions on the human body. It is permitted to be used for treatment.

The LED light source varies slightly in terms of the type of photosensitizer, irradiation wavelength, light irradiation intensity (mW/cm2), light irradiation time (min), and light irradiation cycle (Hz) depending on the bacteria in the nasal cavity, but in general, it is used to kill pathogenic bacteria. It is effective in sterilization, and as the energy (J/cm2) by irradiance (mW/cm2) increases, the death rate of bacteria increases, and light with a visible wavelength of 400nm or more has a sterilization effect similar to UV when used at high energy. can show the effect.

The intensity of irradiance (mW/㎠) for effective sterilization of pathogenic bacteria in the nasal cavity is closely related to the light irradiation distance, and the irradiance is one minute or one tenth of a tenth at a distance of 5-10 cm from the patient's treatment site. It has the characteristic of weakening intensity.

Accordingly, the medical field using LEDs, which have advantages compared to lasers as an alternative light source for low-power lasers, are expanding. They are safe as there is almost no damage or direct tissue damage caused by LEDs, and light of various wavelengths is widely and easily transmitted. It is effective and economical because it can be arranged to treat a wide area.

In photodynamic therapy (PDT) using LEDs, an effective method of removing nasal bacteria is to simultaneously irradiate all parts of the nasal cavity with high intensity irradiance (mW/㎠) at a close distance of less than 10 mm, thus eliminating pathogenic bacteria. It can increase the sterilizing power of.

In addition, light irradiation devices using LEDs are used for various treatment areas such as the skin, eyes, nasal cavity, and oral cavity, and are also used to treat wounds or inflammation in the nasal cavity.

Specifically, LED light irradiation devices that irradiate near-infrared rays to treat dry mouth, stomatitis, tonsillitis, oral inflammation, and periodontal disease are widely known.
