[Detailed description of the invention] Title of invention Medical phototherapy device field of invention The present invention relates to medical phototherapy devices, including but not limited to acupuncture, dental fEl is intended for use in medicine, including medical, physical therapy and veterinary applications. Ru.

This invention further controls instruments at the medical laboratory stage by controlling the interaction of light sources. This enables its use in proving the medical value of medical phototherapy.

The light energy to which this invention relates can penetrate the biological structures of animals, including humans. can be done. Preferably, such light energy is delivered to the living body using a laser. Applicable to structures, the invention is described below in connection with the use of specific lasers.

This device is called “acupuncture treatment computer using therapeutic energy with laser information processing function”. 8 cupuncture Col + 1 puterised unit by La5er IntclligenL Treat High■shitan@E It is called ``Aculite (＾CυshiITE)'', which is an acronym for ``ner8y　)''. .

Background of the invention Laser beams placed at a distance from or in direct contact with the animal's skin. The use of lasers in the medical treatment of animals, including humans, is well known.

The energy of the laser light can penetrate into the animal's anatomy and provide various therapeutic effects. .

The therapeutic effect depends primarily on the amount of energy introduced into the biological structure to be treated. Guidance The amount of energy input depends on the energy density of the laser beam and the laser beam applied to the biological structure. It is the product of the periods that can be achieved. Structures just below the skin surface per square meter Experience clear therapeutic effects by applying 1 to 2 joules of laser light energy However, deeper biological structures require larger amounts of energy.

The practical limit on the amount of energy that can be bound to biological structures is typically 5 joules per torr. The greater energy density is found in animal skin and/or or tend to damage vital or biological structures and, therefore, are generally avoided. It will be done. Most treatments are based on the amount of energy that can be coupled to biological structures per unit time. Ku. For example, a 30 mW laser source delivers 1.8 Joules or It is said to provide energy of 0゜030W x 60 seconds = 1.8 joules. .

This application of energy reduces the energy of the laser light from the laser source to the biological structure. Assume 100% of -. However, there are significant reflections on the animal's skin surface. I found out. The reflection may be due to the skin's natural oils or flakes on the skin. However, it may still occur even when these two factors are less present. stomach. In fact, the skin seen under a low-power microscopy appears to be silver foil and highly reflective. Seem. To prevent this from entering optical runaway, a solid-state laser diode is used. Combine that laser diode with a photodiode to control it. solid state laser Due to the nature of the structure of the diode, the laser light reflected from the animal's skin is transmitted to the photodiode. This indicates that the laser diode is approaching optical runaway. and Therefore, the photodiode does not attenuate the effective output of the laser diode. That's it. For example, if 20% of the laser light is reflected by the skin, the laser light 80% of □ enters the biological structure.

In traditional medical laser treatment equipment, the solid-state laser diode is fixed for treatment. It is driven with a power selected to produce the required energy for a period of time. but However, some of the laser light is not coupled into the biological structures, so the desired dose of energy is Rugi is not applied. Therefore, the effect of laser light therapy was not as expected; Failure to succeed is not easily explained by the user of the device.

In addition, in acupuncture therapy, it is important to manipulate the acupuncture needle to further stimulate the animal's vertex. It is knowledge. In laser light therapy, the same effect as needle manipulation in acupuncture therapy is achieved using a laser diode. This is achieved by modulating the output of the However, the modulation should be carefully It must be controlled to avoid distortion introduced by the modulating signal.

If we introduce distortion, we can predict the effective modulation of the output of the laser diode operation. This leads to stimulation of the upper and lower parts of the body structure, and therefore the operation of the medical phototherapy device is impaired. becomes inaccurate. These inaccuracies make the device unsuitable for laboratory-grade test equipment. It will no longer be.

The exact operation of the laser diode 12 is This can be achieved with Che element 104, and therefore the optimal stimulation of DNA/RNA is achieved by laser energy. can be achieved for many effective applications of energy. Using multiple microprocessors allows you to control individual functions in real time. In addition, control accuracy is important for treatment planning. Reproducibility was achieved and therefore MLTAlo, 100, 200 and 300 are laboratory instruments. It can serve as a first time in this field to provide clinical experiments.

MLTAloo and 300 have also been monitoring the temperature of laser diode 12; Advantages of being able to control the laser diode 12 for greater stability during operation has. Similarly, the voltage and current to the laser diode 12 can be monitored and therefore The operation of the laser diode 12 can be controlled.

The MLTA300 also precisely controls the modulation of the laser diode 12 to eliminate distortion. operation of the laser diode 12 at an unknown output level. can be avoided.

MLT describes numerous variations and modifications without departing from the basic principles of the invention. It will be clear to those skilled in the art what A would do. For example, the keypad 20 is dedicated to the key parameter dryer 1 and labeling, i.e. having non-QWERTY. The sharp 6 key band 10 can be placed with a voice command module and a voice synthesizer. It can be replaced. All such modifications and variations are within the scope of this invention. and its nature should be determined from the above description.
