Description

The field of technology

The technical solution deals with the construction of a photothermal regeneration device (biolamp) for personal purposes with high power without the need for polarization for tissue regeneration with the application of power LEDs for surface mounting with a wavelength in the near infrared region.

Current state of the art

Biolamp, a device intended for biostimulation and phototherapy applications, is used to treat certain diseases. Either a halogen bulb or LED diodes with a wavelength in the range of 630 - 950 nm (red - near infrared) or a laser are used as a source of radiation. The output radiation is usually adjusted by a linear or circular (or elliptical) polarization filter. As a filter, a linear polarizing film is used, or polarizing plates, where the Brewster angle is used. This radiation irradiates the skin. Unfortunately, polarizing techniques absorb a significant amount of radiation, usually around 60% (linear polarizing film), which also reduces the stimulating effect of the biolamp. In addition, the radiation energy is reduced by the part that is reflected from the skin and depends primarily on the distance of the source from the skin. Currently, biolamps using halogen lamps and low-power LEDs (636 nm, red) are on the market. Their radiated power ranges from 2.5 to 90 mW/cm ² . Some solutions in the mentioned field of technology are also published in the patent literature.

Patent document US6,955,684 B2 "PORTABLE LIGHT DELIVERY APPARATUS AND METHODS" discloses a biolamp solution where radiation sources are used in a design with terminals for through-hole mounting technology, which reduces the possible performance of the device. This solution has a separate LED module from the control.

Document US6,860,896 B2 "THERAPEUTIC METHOD AND APPARATUS" describes the method of applying the biolamp to various body surfaces under the influence of radiation. The proposed device is not integrated and consists of several blocks. The proposed ways of addressing individual LEDs in the visible area can cause an epileptic seizure.

Document US2006/0282134 A1 "PHOTO-THERMAL THERAPEUTIC DEVICE" describes a photothermal therapeutic device that consists of several parts and heat is obtained mainly from passive components (resistive heat), while this heat is generated and regulated directly on the LED module as a secondary effect of generation heat when emitting LEDs.

Document US2007/0239233 A1 "SURFACE MOUNT LIGHT EMITTING DIODE MEDICAL APPARATUS" discloses a solution for an integrated biolamp using surface mounted LEDs. It differs from the proposed solution in a different way of construction, attaching the LED with the absence of temperature regulation, and the document US2010/0331930 A1 "PHOTOTHERAPY DEVICE" describes the construction of a biolamp with a separate LED emitter and control. It uses LED diodes in the version with terminals for the through-hole mounting technology, the drawback of which is the limitation of the possible performance.

The essence of the technical solution

The essence of the technical solution consists in the construction of a photothermal regeneration device (biolamp) using powerful LEDs with a minimum distance from the application area to increase the regeneration efficiency. A biolamp working in the red and near-infrared range using powerful LEDs consists of a biolamp body with air channels for heat removal, an LED module on which there is at least one LED, a microprocessor unit with a power driver, control buttons, a display and a USB connector. while the LED module is placed in a cover with a protective film and the microprocessor unit is protected by an electronics cover with a front film. The protective film is transparent or linearly polarized or circularly polarized. Air channels are created between the LED module and the correspondingly shaped body of the biolamp. The photothermal regeneration device (biolamp) is equipped with a fixation belt threaded through air channels for attachment to the affected area.

The LEDs are controlled from the microprocessor via a power driver. This solution provides setting of the mode (pulse, continuous), power and timer, the use of which is suitable, for example, during sleep. The pulse mode with frequencies of 10 Hz, 5 Hz and 1 Hz is suitable for repeated applications of regeneration where there is no significant heating of the radiation source. It is possible to choose a pulse mode with power regulation and its limitation when the specified temperature is reached. In a technical solution, the advantage of the pulse mode is that the wavelength used is outside the range of the visible spectrum of human vision, that is, it is invisible to humans. This prevents undesirable phenomena such as inducing an epileptic seizure in the pulse mode. The pulse mode delivers the highest possible dose of radiation to the regenerated tissue and does not induce a memory effect of the cells. The continuous mode is suitable for thermostimulation applications, for example for colds. In addition to the radiation source with a wavelength of 860 nm, the power LEDs generate heat secondarily, which is used in the solution to heat the application plate of the biolamp and helps with colds and flu. The electrical circuits enable the biolamp to be powered from various energy sources, for example an external battery, mains adapter, USB socket in the car, from a PC, etc. Cooling of the power LEDs is ensured by the construction of the biolamp and natural air flow. The LEDs are mounted on the surface of the MCPCB (Metal Core Printed Circuit Board) board, which ensures heat distribution from the point sources of the LEDs to the surface source. The number of LEDs can be different, there can be at least one. Similarly, the application surface can have different shapes from a simple surface to curved surfaces. The biolamp is applied to the affected area using a fixation belt that fixes the biolamp to this area. The technical solution can also be used when moving, for example when walking. The individual modules of the biolamp are integrated in one package, which simplifies its use. The number of LEDs depends on the required power and the specific application.

The maximum temperature is regulated electronically, using a microprocessor according to user settings in a defined range from 40 to 70 °C, which ensures an adjustable photothermal stimulation effect. The protective film is made of a material that allows the use of common disinfectants to disinfect the contact surface. The packaging of the photothermal regeneration device is made of durable plastic suitable for contact with the skin. The photothermal regeneration device includes an element for generating an audio tone and/or melody to announce the end of the selected stimulation program, which can be a piezo speaker.

Implementation examples

In fig. 1 is the layout of the components of the photothermal regeneration device, which consists of a microprocessor unit 5 with a power driver, a temperature sensor, control buttons, a display and a USB connector 5a, to which an LED module 3 built on a heat-conducting board (MCPCB - metal core printed) is connected with an air gap circuit board) with LEDs 3a on its surface. The LED module 3 is covered by the cover 2 of the LED module and the protective film 1. The board of the microprocessor unit 5 is stored in the body 4 of the photothermal regeneration device and equipped with the cover 6 of the electronics with the front protective film 7. The photothermal regeneration device is equipped with a fixing belt 9 passed through the air channels 8 - fig. 3. The maximum temperature is regulated electronically, using a microprocessor according to user settings in a defined range from 40 to 70 °C, which ensures an adjustable photothermal stimulation effect. The protective film 1 is made of a material that allows the use of common disinfectants for disinfecting the contact surface. The packaging of the photothermal regeneration device is made of durable plastic suitable for contact with the skin.

In fig. 2 shows a block diagram of a biolamp. The USB-C connector is used to connect the power source to the circuits of the biolamp. MCU, a microprocessor provides control of the photothermal regeneration device, which includes user settings of mode, timer, power and maximum temperature. The setting is carried out using the control buttons and the display, which, in addition to the setting, shows the current state of the photothermal regeneration device. The microprocessor ensures the regulation of the LED module through the power driver, while it checks the temperature of the LED module using a thermal sensor and adapts the power to the LED module accordingly. In the case of powering the photothermal regeneration device from the power bank, the microprocessor keeps it in an active state by artificially increasing the consumption from the power bank every 10 seconds. If the photothermal regeneration device is not used for more than 2 minutes, this algorithm is deactivated and the powerbank turns off after a certain time. The end of the stimulation program is accompanied by a sound signal (tone or melody), as well as by pressing any button using the built-in piezo speaker.

Industrial applicability

Biolamp with photostimulation and thermostimulation effect is used for therapeutic purposes, primarily for stimulation of cells and tissues with penetration to a depth of 9 mm. It is recommended to use for wound healing and healing of 5 scars, treatment of diabetic foot, cold, joint and muscle pain and many other problems.
