Description

Transcutaneous laser therapy patch.

Technical sector

The present invention relates to an apparatus of Low intensity laser therapy for transcutaneous application and instant anywhere in the body for the treatment of different medical pathologies or aesthetic treatments.

State of the art

The low intensity laser class IIIA, IIIB and IV is applied therapeutically by irradiating both large body surface areas and punctually over small areas for the treatment of multiple diseases such as tendonitis, tendinosis, peripheral paralysis, muscle allergies, epitrocleitis, epicondylitis, sprains, rhizarthrosis, Talalgias, dorsalgias, osteoporosis, bruises, herpes zoster, arthralgias, muscle contractures, neuralgia, arthritis, sciatica, periarthritis, osteoarthritis, gonarthrosis, cervicoarthrosis, edema, fractures and wounds. These therapeutic applications extend to different medical specialties: traumatology, rheumatology, dermatology, vascular, dentistry and neurology. (Jan Tuner and Lars Hode: Laser Therapy. Clinical practice and scientific background. Prima Books, Sweden,
2002).

The therapeutic effects of low laser intensity are based on biochemical, bioelectric effects and bioenergetics that produce photons in their interaction with biological structures These effects are increased adenosine triphosphate (ATP) and protein production, increase of cell proliferation and trophism, increased microcirculation, membrane permeability changes cellular, elevated levels of endorphins and serotonin, increased of lymphocytes and increased lymphatic flow.

The traditional technique of applying the Low intensity laser therapy is performed using equipment located in hospitals and clinics for a certain number of sessions and through short periods of time. The big limitation existing in the clinical application of this technique consists of the existence of a period of time from its clinical indication to its therapeutic application in the patient and not having it technique immediately or domiciliary. In the technique of skin contact laser energy penetrates deeper, it applies through probes that the therapist applies manually and You need more treatment time.

The non-contact technique uses higher density laser power to compensate for the distance between the beam opening and treatment area, effective times of treatment are shorter and usually radiate the beam automatically in sweeping over the fabric.

In both techniques the depth of action of the low intensity laser therapy, adding the direct effects and the indirect ones, can reach up to 3 cm and is a function of the wavelength, intensity and collimation of the beam and the anatomical feature of the application surface.

The different parameters that are part of the correct selection of the low laser therapy dosage intensity are: the nominal power of the laser (milliwatts, mW), the laser power density (watts per square centimeter, W / cm2), energy (Joules, J), energy density (Joules per square centimeter, J / cm2), the surface area of treatment (square centimeter, cm2), the distance from the laser emission point to the therapeutic objective (centimeters, cm), the irradiation time, the modality of the emission: pulsatile or continuous, the duty cycle (%), the pulse repetition rate (cycles per second or Hertz, Hz), the pulse duration (nanoseconds or microseconds, ns or ms), the laser wavelength (nanometer, nm) and the divergence of the beam (degrees, °).

The low laser energy dosage intensity is comparable to a pharmacological model in which we supply a substance in a given dose in order to Get a therapeutic effect.

The most used parameter for the dosage of Laser therapy is energy density, which is quantified in Joules / cm2 and for its calculation the following is used formula:

J / cm2 = \ frac {Power \ media \ (W) \ x \ Time \ of \ exposure \ (s)} {Area \ of \ the \ surface \ (cm2)

There is a dosage of laser energy for the treatment of different pathologies depending on the parameters above based on experience therapeutic of the years of use of this technique. For example the dose of energy density for low back pain (6 J / cm2), periarthritis (6 J / cm2), gonarthrosis (4 J / cm2), epicondylitis (3 J / cm2), sprain (4 J / cm2), syndrome of carpal tunnel (4 J / cm2). In general the dosage based on The energy density ranges from 1 J / cm2 to 99 J / cm2.

The laser therapy equipment is currently developed in the solid state or by laser diodes semiconductor. High-light LEDs (LED) intensity have minituarized this technology which have allowed the use of irradiation for the diagnostic purpose of the laser in small or specific areas such as in Doppler laser equipment, Oxymetry laser or laser spectroscopy.

In the treatment of different diseases uses the permanent or transient transcutaneous application of Different types of therapeutic patches.

Explanation of the invention.

The present invention relates to a patch of laser therapy for transcutaneous application, application Instant, automatic operation and use domiciliary.

The laser therapy patch consists of a source of power or battery, control circuit that monitors the operation and activates the laser diode which generates a laser beam of visible or infrared light.

The dose is administered instantly and automatic by activating the patient with a button "on" and deactivation by an "off" button (although both functions can be performed by the same button "on / off" according to the previous state and in order to simplify and reduce space).

The laser patch is placed transcutaneously and all the parameters that form the energy dosage lasers remain constant except the exposure time that it varies with what we generate a different energy density For each disease.

With the laser patch, the dosage of the laser energy applied in each treatment according to its pathology is based on which parameters to calculate energy density (J / cm2), average power (W), energy (J) and the area of the Treatment surface (cm2) remains fixed by varying exposure time as a function of energy dose (J) indicated for each treatment.

From the above we obtain an energy density different for each clinical situation according to the formula:

Time = \ frac {\ text {Surface Dose}} {\ text {Power half}}

The average power is calculated as next:

Average power (Wm) = Wp x Tp x F

Where Wm is the average power (W), Wp is the peak power (W), Tp is the pulse duration (ns or ms) and F the pulse rate (Hz).

In the most simplified mode, the power considered will be the maximum power of the laser diode since no pulse work regime is applied being its operation continuous and therefore the average power will be equal to the maximum of laser diode

Time (s) = \ frac {Energ \ text {í} a \ (J) \ x \ Surface \ (cm ^ {2})} {Power \ half \ (W)}

The advantages of this method of application of Laser therapy are: reuse capacity by it sick for an indeterminate number of sessions (the stack can be replaceable), localized therapeutic action, non-invasive technique and painless, transcutaneous placement, immediate application and Instant, non-pharmacological therapeutic agent, offers multiple treatment pathologies, portable application (the assistance to clinics or hospitals for its application), technique Complementary or alternative to traditional therapy, activation Very simple and automatic operation, low consumption and low cost. When the laser is located in the part in contact with the skin and being the upper part of opaque material it is not necessary to carry glasses for therapeutic use.
