Description

The utility model relates to medical equipment, namely, devices for phototherapy, preferably children from infancy to 4 years.

Until recently, only blue lamps were used to prevent and treat mild and moderate forms of acute respiratory viral infections in maternity hospitals, as well as in physiotherapy departments of children's clinical institutions.

The generated light emission of the blue region of the spectrum is scattered and does not produce a spot focused on the sore spot.

A device is known for irradiating oral cavity and larynx in children, including a red light source, characterized in that an emitter is a LED mounted in a pacifier, which plays the role of a light-scattering screen (RF patent No. 2074752).

This device is effective for healing small wounds, but ineffective for the treatment of acute respiratory viral infections, especially common among young children.

A LED irradiating device is known, including a pacifier, a light emitting diode, and an autonomous power source with a microcontroller and a sealed contact is hermetically mounted in the body of the nipple (RF patent No. 28035).

As mandatory features, RF patent No. 28035 does not indicate what kind of light irradiates, but when it is absorbed exactly blue light, the blood circulation improves, especially at the microcirculation level, respiratory functions are activated, oxygen delivery and utilization by tissues are enhanced, and hemorheology system regulation is observed and hemostasis. In this case, an activation of metabolism, a decrease in the level of atherogenic

blood lipids, normalization of metabolic parameters and stimulation of the activity of the immune system.

The closest analogue is the LED device, which includes a pacifier with a monochromatic blue LED hermetically mounted in it, an autonomous power supply with a microcontroller and a sealed contact, and a restriction ring (LED pacifier "LIGHT SM SM" TU 9444-003-18898190-2003-09-23 )

The light radiation created in the known device can only be constant, the possibility of obtaining alternating radiation by the known device is not provided. A self-contained power supply with a microcontroller integrated in the nipple housing provides a total of 150 starts. The known device does not take into account that when a child flips on one side, a solid ring can disturb, wake him, injure his cheek.

The technical result achieved by using the proposed utility model is to create a more durable physiotherapeutic device, lightweight, convenient, safe, comfortable, especially for infants, providing an additional therapeutic effect, which consists in stimulating blood supply and oxygen uptake.

The achievement of the technical result is ensured by the fact that in a physiotherapeutic device including a pacifier with a monochromatic blue LED hermetically mounted in it, an autonomous power supply with a microcontroller and a sealed contact and a restrictive ring with a washer, the microcontroller is made with an internal 32 kHz oscillator having a zero mode power consumption, providing a supply of pulse voltage with a frequency of 50 Hz, and the restrictive ring with a washer made of silicone material .

Preferably, the pacifier is made of a transparent latex or silicone material.

The use of a therapeutic resonant frequency of 50 Hz further stimulates blood supply and oxygen uptake.

Used for the manufacture of the restrictive ring and washer medical silicone material (in contrast to hard polypropylene) allows you to make the proposed device lightweight, soft, durable and safe.

The microcontroller used, preferably 4 × 4 mm in size, allows you to increase the number of inclusions (when using a single current source) up to 400 turns.

As the microcontroller, the MLF-20 device is preferably used, designed for a voltage of 1.8-6.6 V.

The electronic unit is preferably sealed with SIEL 159-356 compound TU 6-05-11552412-007-95 of modification PKMB-03.001-03. As a radiation source, for example, LEDs EQL-5GBCCCO-EG or EQL-5GBCCCV-EG from EQL Excellence opto.inc., USA, manufacturer Taiwan. For the manufacture of a key card, a magnet is preferably used according to TU 3498-001-10856794-92.

Each LED physiotherapy device is packaged in an individual consumer packaging - a reusable polymer packaging in the form of a cup, with an airtight lid, which provides for disinfection with a 3% solution and sterilization with a 6% hydrogen peroxide solution in accordance with OST 42-21-2-89. Packing material - food polyethylene.

The proposed device is presented in figure 1, in section, where:

1 - soother, 2 - ring with a washer; the electronic unit is represented by the positions: 3 - LED, 4 - battery, 5 - microcontroller,

6 - sealed contact "Reed switch", 7 - a cup with a sealed lid in the context.

The exposure time (3 min) and the radiation intensity (0.3-0.5 milliwatts) are programmed in the microcontroller. The device can be used while the patient is sleeping.

LED physiotherapy device operates as follows.

A key card is brought to the electronic unit, thereby closing the “Reed” 6 contacts, an electric current passes through the microcontroller 5 to the monochromatic emitter-LED 3, creating a pulsed emission of blue light for 3 minutes.

The proposed device and packaging have passed a toxicological study in accordance with the documents:

- Standards of the GOST R ISO 10993 series "Assessment of the biological effects of medical devices":

"Part 1. Assessment and research ”

"Part 10. The study of irritating and sensitizing effects "

"Part 11. Sample and standard preparation ”

- GOST R 51148-98 “Medical devices. Requirements for samples and documentation submitted for toxicological, sanitary and chemical tests, sterility and pyrogenicity tests ”

- “A collection of guidelines for toxicological and hygienic studies of polymer materials and medical products based on them”, Ministry of Health of the USSR, 1987

- GN 2.3.3.972-00 “Maximum allowable quantities of chemicals released from materials in contact with food”.

The research results showed the complete toxicological safety of the claimed device.

The device underwent clinical trials, which showed a decrease in the duration of treatment in comparison with the prototype due to additional stimulation of blood supply and oxygen uptake due to the therapeutic effect of a variable frequency of 50 Hz.

In addition, when using the same power source, it is possible to provide 400 turns, instead of 150 turns, as in the known device.

Due to the use of silicone materials for the manufacture of the restrictive ring and washer, the device is absolutely safe and very light.

The device is easily sterilized in packaging containers, if used in stationary medical institutions and organized children's groups.
