Method for treatment of fingernail and toenail microbial infections using infrared laser heating and low pressure
A method of treating microbial infections, which consists of the steps of sequentially and repeatedly irradiating the microbe with continuous or pulsed infrared radiation and continuous or pulsed cooling such that heat and cold alternatively penetrates to the site of the infection in order to inactivate the pathogen.
1. A method of treating microbial infections in the nail of a toe or a finger, the method comprising the steps of: sealing the site of microbial infection within a vacuum chamber that fits over a toe or finger, thus creating a sealed chamber surrounding the toe or finger, wherein the vacuum chamber made of a material transparent to infrared radiation; irradiating the microbes through the transparent vacuum chamber with infrared radiation; and inducing mechanical damage to the site of the microbial infection by applying low pressures and temperatures between 45 degrees Celsius and 60 degrees Celsius.
2. The method of claim 1 , further including the step of using pulsed radiation with a wavelength that is selectively absorbed by the microbes and with a pulse length that is chosen to match the thermal diffusion properties of the microbe.
3. The method of claim 1 , further comprising the step of introducing gold nanoparticles (GNPs) or other particle seeds to create a rapid and violent thermoelastic expansion or cavitation of the microbial infection, thereby increasing the disinfection efficiency during laser irradiation.
4. The method of claim 1 , wherein the microbial infection is a toenail fungus or infection.
5. The method of claim 1 , further comprising the step of hydrating the site of microbial infection prior to irradiating with infrared radiation.
6. The method of claim 5 further comprising the step of hydrating the toe or finger nail by bathing in warm water.
7. The method of claim 1 , wherein the step of irradiating the microbe with infrared radiation is performed using laser energy having a wavelength between 1450 nm and 1550 nm.
8. The method of claim 1 , wherein the step of irradiating the microbe with infrared radiation is performed using laser energy having a wavelength of 1470 nm.
9. The method of claim 1 , wherein the vacuum chamber further comprises (I) an open end having a circular sealing member, (ii) a central tubular section, and (iii) a sealed end, the method further comprising the step of sealing the vacuum chamber around the site of microbial infection with the circular sealing member to create a vacuum therein.
