Description

Laser / LED pad for photochemical therapy {laser / LED pad for use in photochemistry medical}

The present invention relates to a photochemical therapeutic laser / LED fabric, and more particularly, by arranging semiconductor lasers or LEDs in an array form at appropriate intervals and accommodating them in a mat, a wide lesion having a diameter of 10 cm or more may be formed in the shape of a lesion. The present invention relates to a photochemical therapeutic laser / LED fabric that can be evenly irradiated accordingly.

The photo-chemical action on plants can be seen in the carbon assimilation. When light is irradiated to a living body, it is known that ATP is produced by the optical action to activate cells. In other words, when the laser light is irradiated to the living body with low energy that does not damage the living cells, the physiological function of the living body is activated and the natural healing power of the affected area is already enhanced. Experiences in laser surgery have been well known in the medical field.

Recently, Low Level Laser Therapy (LLLT), which actively uses this action to treat various diseases, has been developed and started to be used in various disease fields.

The biochemical action of light is determined by the wavelength, polarization, and intensity of light. According to the experiment, light having energy of about 100mW as the polarization in the range of 600um-1000um is known to be the most effective.

Such light can be generated by using a He-Ne laser, a semiconductor laser or a YAG laser. Especially, in terms of size and price, semiconductor lasers are advantageous, and now GaAs (904 nm) and GaAlAs (780-820-870 nm, InGaAlP ( 630-685 nm) is mainly developed and sold.

However, it has been reported that instead of such lasers, it is also possible to use the light emitted from the LED, which is particularly adopted for products that emphasize manufacturing costs. Since LEDs are not coherent light like laser light, they can't focus the beam width to some extent, and if they aren't polarized, they can produce light in the 600-1000 um region and can guarantee an intensity of around 100 mW / cm. The effect is almost the same as using a semiconductor laser.

The most widespread use of LLLT therapy is in pain treatment, and it was developed by Professor Plague of Canada, who used He-Ne laser to irradiate acupuncture points in the form of laser acupuncture to get a great effect on pain relief. . Currently, not only acupuncture points, but also direct examination of the affected areas have been found to be very effective in healing pain as well as the disease itself. In particular, LLLT not only has an excellent effect on various chronic diseases known as refractory, but the treatment technology is inherently non-invasive (non-surgical), non-invasive, has little pain and side effects to patients, and has no burden of medical expenses. There are significant advantages over traditional treatments.

However, the therapeutic devices developed for the purpose of LLLT so far are suitable for menstrual blood irradiation where the irradiation diameter is narrow within a few centimeters, but it is inadequate when a large area of irradiation is required. Especially in the case of promoting the healing of the surgical site after surgery, treating a wide range of inflammation, etc., in order to activate a wide range of living cells by evenly irradiating light on a broader surface than menstrual blood, or when a non-specialist wants to treat at home It requires a light source with a large diameter of about 10 cm.

In addition, the short wavelength of 600-700um is absorbed by hemoglobin and the long wavelength of 1,000um is well absorbed by fat and water to activate the cells of the part. effective. However, since the wavelength and output of the generated light are determined by the semiconductor material and structure, the laser diode cannot be arbitrarily adjusted to the wavelength or output that is optimal for a particular disease or affected part.

Therefore, it is necessary to make an array by mixing two or three kinds of semiconductor lasers or LEDs having different characteristics and to switch them externally.

In addition, in the case of using a plurality of arrays of laser semiconductors, the fabrication cost of the fabric increases. For cost savings, it is necessary to adopt a method that uses LEDs with wavelengths similar to those of semiconductor lasers, although less effective.

Accordingly, an object of the present invention is conceived by the above-mentioned problems, and the semiconductor laser or LEDs are arranged in an array form at appropriate intervals to be accommodated in the mat, so that a wide area of 10 cm or more in diameter is formed in the shape of the affected part. Its purpose is to ensure that you can evenly investigate.

In order to achieve the above object, the present invention uses a plurality of semiconductor lasers or LEDs to make a flat array (array) to attach to or attach to a cushion or cutting type flexible foam (contact) in contact with the affected area when used It is characterized in that the light is irradiated to a large area to enable low-power photo-chemical treatment (LLLT or LEDT).

In addition, in the LLLT or LEDT treatment device, two or more mixed light source elements are installed in a soluble forge of the cutting type so that the wavelength and output of the irradiation light can be switched as needed. It is characterized by a semiconductor laser or LED device.

In addition, when the instantaneous output and the irradiation time of the irradiation light is set, it is equipped with a control device that automatically switches or flashes the irradiation light, and always monitors the total dose and a safety device that automatically cuts when the allowable amount is exceeded.

Objects, features, and structural points of the present invention described above will become more apparent from the detailed and preferred embodiments of the present invention described below with reference to the accompanying drawings. It should be noted that in the drawings, the same to similar parts are described with the same to similar reference numerals for convenience of explanation and understanding.

Before explaining the configuration of the present invention will be described with reference to FIG.

The laser diode (LD) is driven by the output intermediate amplifier PA. The light output is automatically controlled by a feedback control circuit consisting of a white noise generator WNG, a low pass filter LPF and a pulse width generator PWM.

In general, the output of the laser diode (LD) is easily changed by ambient temperature, power supply voltage, etc. In this case, the laser diode (LD) is not only at risk of burning out but also affects the treatment effect. It is designed to be suppressed. In addition, as the ambient temperature rises or the battery voltage increases, the noise power of the WNG increases, so the low-frequency components that pass through the LPF also increase, thereby reducing the duty cycle of the pulse width generated by the PWM. "Time is short.

The LED is an indicator that the LD is operating.

That is, when the main switch is turned "on" to operate the laser diode LD, the power is supplied to the LED driving circuit DRV simultaneously with the LD via the electronic switch ESW to "turn on" the LED. The electronic switch is not only a switch but also serves as a power stabilizer circuit.

The LLLT or LED therapy device operating on the principle described above will be described with reference to FIG. 2.

1 is the external appearance of the fabric of this invention.

The fabric 1 is made of thick insulating paper, and a flexible circuit board 2 as shown in FIG. 3 or 4 is installed therein.

On the circuit board 2, a laser semiconductor or an LED element 3 is arranged.

The semiconductor device 3 is divided into two modifications, one set (3a) and two sets (3b), and each uses a semiconductor having different characteristics.

Since the circuit board 2 is made of a flexible PCB, the shape can be changed without difficulty according to the shape of the edge 1. At this time, the suspenders 1 are attached to four suspenders 5 so that they can be firmly fixed to the affected part.

4 is the power supply cord.

In addition, a far infrared ray emitting medium 10 as shown in FIG. 7 is provided on the circuit board 2, and a laser semiconductor or an LED element 3 is fixed to the far infrared ray emitting medium 10.

That is, the far infrared ray emitting medium 10 is manufactured in a donut shape, and the laser semiconductor or the LED element 3 is fixed to the center installation hole 11.

At this time, the far-infrared ray emitting medium 10 may be natural jade or elvan rock, lumber stone, gold, copper, and may be used to put the pressed charcoal in the cloth (1).

Further, the laser semiconductor or LED element 3 is protected by the lens 3c, as shown in the enlarged view of the main part of FIG.

As described above, the photochemical therapeutic laser / LED fabric 1 is configured by first arranging a laser semiconductor or an LED element 3 on the flexible circuit board 2 at regular intervals to form a laser array. This allows the LED to emit light evenly over a wide area.

At this time, in general, in the semiconductor laser or LED device, the wavelength and output of the generated light are uniquely determined by the material and structure of the semiconductor.

Therefore, in order to generate light having a wavelength and intensity that is optimal for treatment, two or three kinds of semiconductors may be mixed and appropriately used.

For example, in FIG. 3, one tank 3a is a 100mW element, and two tanks 3b are 10mw, or one tank 3a is 800nm and two tanks 3b are 1000nm. By selectively switching and supplying (4), it is possible to appropriately switch the irradiation wavelength or irradiation intensity of the whole gun.

The arrays alternately arrange two different wavelengths or output semiconductors so that the wavelength or output can be switched in two stages as needed.

Thus, the two arrays are each connected to independent power lines and are properly switched by an external controller (not shown).

Next, the array circuit board 2 made as described above is enclosed in an insulating cloth as cozy as possible as shown in FIG. 6, and only the lens 3c portion of the laser element or the LED 3 is out as shown in FIG. Get out.

The photochemical therapeutic laser / LED fabric 1 made as described above is mounted in close contact with the skin of Fig. 5 and the affected part, and irradiated with laser light for a predetermined time. At this time, the irradiation time depends on the wavelength, output and waveform of the light. The total dosage is automatically adjusted by the controller according to a separately calculated standard.

As described above, the inventive photochemical therapeutic laser / LED fabric has the following effects.

First, the LLLT technology, which has been applied only to menstrual blood irradiation because of the small beam width of light, can be evenly distributed to a wider area. Chronic joint rheumatism, fifty shoulders, acute low back pain, cervical spine, and tendinitis Gout, sprains, bruises, arthritis, stress gastritis, atopic dermatitis, jaw arthrosis, stressful colon syndrome, asthma, hay fever, autonomic ataxia, paralysis due to cerebrovascular disorders, polio, Alz Hyma and Parkinson's can treat diseases such as senile plaque, menopausal mental and physical disorder, muscle paralysis and cramps, and numbness.

Second, by using LED arrays, more inexpensive photo-chemotherapeutic devices can be developed and more economical treatments are possible.

Third, by arranging two or three kinds of light emitting devices, a photo-chemical treatment device capable of varying the output and the wavelength may be implemented as necessary.
