Embodiment two

Step 201: the position that will contain fungus is cleaned;

Instep 201; In the process of cleaning, some foreign material flush awaies that the position that contains the fungus that remains to be killed can be contained like this, in the process of using ultrasonic sterilization, are convenient to ultrasound wave and directly act on the fungus, and moment are with its deactivation.

Step 202: form ultrasound wave and focusing, obtain concentration ultrasonic;

Instep 202, be specially the process of focus ultrasonic, its process is to utilize ultrasound wave as the energy, and hyperacoustic a lot of wave beams are transmitted into the internal medium from external environment condition, focuses in the middle of the transmission process, and focus on the point, transform by sound wave and heat energy, form a high-temperature area in a short period of time, when high-temperature area is in the position at fungus place, can be with the fungus deactivation, its principle is similar to the poly-sunlight of solar cooker and produces huge energy in the focus place.

Step 203: concentration ultrasonic is aimed at the position of containing fungus;

In above-mentionedsteps 203, concrete, after ultrasound wave focused on, all energy were focused in the very little zone, and therefore, when its aligning contained the position of fungus and certain time, a large amount of funguses then can be inactivated.

When the concentration ultrasonic aligning is contained the position of fungus, can can realize by the effect of the temperature at irradiation position rising second at the position chronic exposure 1-5 that contains fungus, the temperature at radiation exposed position can obtain raising in moment, when the temperature of fungus environment of living in raises, the metabolism of himself then can be affected, therefore, fungus can be in the moment deactivation.

Step 204: control hyperacoustic wave beam, make concentration ultrasonic mobile at the position of containing fungus, and make the temperature at the position of containing fungus reach 40 ℃-70 ℃.

Instep 204, ultrasound wave after focusing on is aimed at when containing the position of fungus, and when moving in the zone of containing fungus, the whole temperature that contains the zone of fungus will raise, therefore, generally speaking, can reach the purpose of sterilization when temperature reaches 40 ℃-70 ℃, preferred 65 ℃ is best sterilization temperature.

Step 205, the cleaning second time is carried out at the position that will contain fungus;

After fungus passes through the ultrasound wave deactivation, can clean again it, to reach the effect with the fungus flush away of deactivation, optionally, after cleaning is finished for the second time, the most of fungus that is killed by ultrasound wave can be by flush away, and then after reducing fungus that minority do not killed fully it losing ultrasonic irradiation, recovers active probability again.Preferably, the time of cleaning for the second time is for finishing after the ultrasonic irradiation 12 hours.

In the above-described embodiments, preferred, hyperacoustic sound intensity is 2.5-3w/cm²Described frequency of ultrasonic is 1.8 megahertzes-2.2 megahertzes, is preferably 2 megahertzes; Hyperacoustic beam type can be collimation-type, and ultrasound wave is preferably pulse ultrasonic wave, and its pulse duration be the 18-22 millisecond, preferred 20 milliseconds; And the pulse repetition period of pulse ultrasonic wave is the 80-120 millisecond, preferred 100 milliseconds; And then the dutycycle of pulse ultrasonic wave can be maintained 1:5, and working as ultrasound wave in the present embodiment elects as under the prerequisite of pulse ultrasonic wave, when its irradiation contained the position of fungus in 1-2 minute, it can reach the temperature that makes the position of containing fungus and be increased to 40 ℃-70 ℃.

Generally speaking, hyperacoustic sound intensity, frequency are more high, can produce bigger energy after it focuses on, and then can more effectively sterilize, but, consider in the process of operation, if the energy after focusing on is too big, it may have potential harm to human body so, so the sound intensity that ultrasound wave is concrete and frequency serve as preferred with above-mentioned data of being lifted, and hyperacoustic beam type of present embodiment is preferred with the collimation-type, the wave beam of collimated ultrasound is even, is beneficial to focusing more.

In addition, after ultrasound wave focuses on, aligning contains the position of fungus and thereon in the mobile process, the movement of wave beam can be selected straight reciprocating motion or circular motion dual mode, the uniform temperature of temperature that can realize radiation exposed position in the process that wave beam moves like this raises, and reach maximum temperature gradually, and then with the fungus deactivation.In this enforcement, the kind of described fungus is various, for example can be the Mycophyta that causes tinea unguium; As, dermatophytosis (trichophyton, Epidermophyton or Microsporon), candidiasis (candidiasis) and non-tinea mushroom fungus etc.

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
