It is a device for individual use.

Description

The utility model relates to medical technology, namely phototherapy. For the treatment of acute respiratory diseases (ARI) and ENT diseases, the methods of light irradiation of the mucous membranes of the upper respiratory tract, the entrance gate of infection, are now widely used [1, 2, 3]. As a rule, the majority of acute respiratory diseases and ENT diseases are caused by pathogens constantly circulating in the upper respiratory tract. In RU 2316366 and in work [4], in experiments "in vitro" it was shown that the light of the blue spectrum range effectively suppresses the reproduction of opportunistic bacteria, for example, "Staphylococcus aureus". The methods of irradiation of the mucous membrane of the upper respiratory tract with blue light are especially relevant for the treatment and prevention of acute respiratory diseases and ENT diseases. The use of irradiators in the blue spectrum range makes it possible to reduce or completely abandon the use of antibiotics in the treatment of mild and moderate acute forms of acute respiratory infections and ENT diseases. For example, for the treatment and prevention of acute respiratory infections and ENT diseases in young children, various phototherapeutic devices have been developed and used [5, 6].

In patents RU 2260459; RU2286186; RU 2038 and RU 146971 describe a method and technique for the treatment of acute respiratory infections and ENT diseases, as well as modern compact phototherapeutic devices, which are used to treat young children. For ease of use, these phototherapy devices are standard pacifier bodies that house sealed miniature LED electronic components inside. The mucous membranes of the oropharynx and nasopharynx are irradiated with light. The positive experience of the medical use of phototherapeutic devices for the treatment and prevention of acute respiratory infections in young children indicates the relevance of creating self-contained compact photographic devices also for young children and adolescents.

We have carried out clinical trials of experimental phototherapeutic devices UFS "Firefly SM" in relation to this category of patients.

The main findings of these tests are as follows:

A clinical trial of a phototherapeutic, LED UFS "Firefly-SM" device in young, middle-aged and older children (from 2 years to 17 years) in the treatment of mild and moderate forms of acute respiratory infections has shown its sufficient effectiveness.

The duration of the main clinical symptoms (runny nose, cough, swelling and hyperemia of the pharynx, intoxication, sore throat, temperature reaction) was reduced by one and a half times compared with the control group in the vast majority of patients.

The use of the UFS "Firefly - SM" device significantly reduces the risk of bacterial complications (by 33%).

The use of the device significantly reduces the drug load, makes it possible to exclude antibacterial drugs in the treatment of moderate forms of acute respiratory infections.

The use of the device 2-3 times a day during the epidemic period significantly reduces the likelihood of seasonal illness.

The required doses of blue light irradiation to achieve a pronounced therapeutic effect do not exceed 1 J / session.

The test results showed that the patients were well tolerated by the irradiation procedures with the UFS "Firefly-SM" device. Allergic reactions and cases of individual intolerance were not noted.

Based on these clinical trials, it became possible to formulate the main technical requirements for a small-sized, self-contained phototherapy device for the treatment and prevention of acute respiratory infections and ENT diseases in young children and adolescents.

From the existing level of technology known phototherapeutic devices for the treatment and prevention of respiratory diseases, such as: APS [5]; BioNette [6]. A similar device is described in patent RU111766.

Known phototherapeutic device for irradiation of the mucous membrane of the oropharynx of a child, which is used for the treatment and prevention of mild and moderate acute forms of respiratory diseases and ENT diseases, U-Ssd "Firefly SM" [7]; RU 146971. This device is the closest prototype of the claimed model.

It is a LED device with a stabilized dose of irradiation, including a pacifier, in which are built: a light-emitting diode, an autonomous power supply, a microcontroller with an ADC and a sealed contact. The microcontroller sums up the amount of electricity passed through the LED and turns it off when the predetermined radiation dose RU 146 971 is reached.

The U-Ssd "Firefly SM" device is intended for young children, less than 3 years old. The phototherapeutic dose of radiation per session is 0.1 J.

The task to be solved by the declared useful model is the creation of a small-sized, self-contained phototherapeutic device for the treatment and prevention of respiratory infections of the upper respiratory tract in young children and adolescents. This problem is solved due to the fact that a phototherapeutic device for irradiation of the mucous membrane of the oropharynx and nasopharynx, containing a LED electronic unit with a programmable dose of radiation and a light guide, characterized in that the LED electronic unit is placed in a sealed optically transparent plastic container, the bottom cover of which is made in the form a corrugated membrane, and a plastic cylindrical polished light guide with a polished output surface located perpendicular to the optical axis of the device is attached to the polypropylene cover of the device, and the light guide is attached to the polypropylene cover so that the polished end of the light guide is fully illuminated by the blue light of the LED.

The design of a phototherapeutic device for irradiation of the mucous membrane of the oropharynx and nasopharynx is shown in Fig. 1.

A cylindrical polished light guide made of polypropylene or polycarbonate (1) is attached to a polypropylene cover (2) so that the polished end of the light guide (1) is fully illuminated by the blue light of the LED (3) of the LED electronic unit (4), placed in a thin-walled, optically transparent, sealed container (5), the lower end wall of which is made in the form of a flat corrugated membrane (6). The container (5) is inserted inside the polypropylene lid (2) and fixed there with the fixing polypropylene ring (7).

The phototherapy device works as follows: a pre-sterilized light guide (1) is inserted into a polypropylene cover (2) and fixed. LED electronic unit (4) with LED (3), placed in a sealed plastic container (5), is installed inside a polypropylene cover (2). The container (5) is fixed inside the lid (2) with a fixing polypropylene ring (7). The light guide (1) is placed in the mouth or in one of the patient's nasal passages. By pressing the membrane (6), the microswitch of the LED electronic unit (4) of the phototherapeutic device is turned on and the procedure for irradiation of the mucous membrane of the oropharynx or nasopharynx is carried out. The LED electronic unit (4), upon reaching the required radiation dose, is automatically turned off. The procedure is over. If it is necessary to repeat the procedure, it is enough to press the membrane (6) again, before that, wait a pause for two minutes. A pause is necessary to restore the battery's performance. The LED electronic unit (4) is programmed in such a way that it does not allow the device to be switched on again during this pause (2 minutes).

At the end of the work, it is necessary to disassemble the device, for which it is required: unscrew the fixing ring (7), remove the sealed container (5) from the cover (2) with the LED electronic unit (4) placed in it, release and remove the light guide from the cover (2) ( 1).

All elements of the device, with the exception of the LED electronic unit (4), located in a sealed plastic container (5), can be subjected to high-temperature sterilization; for example, boiling for 30 minutes or processing in a steam sterilizer. A plastic sealed container (5) with a LED electronic unit (4) inside it can be washed with hot water at a temperature not exceeding 60 ° C using any detergent. During the irradiation procedure, the container (5) does not come into contact with the mucous membrane of the oropharynx and nasopharynx. After sanitizing and drying the elements of the device, the device must be assembled and stored until the next use, for example, in a plastic container.

The claimed phototherapeutic device can be widely used by patients of different ages. It is easy to use and maintain and quite effective, especially in the early stages of the disease and as a preventive measure. The device is self-powered from a built-in 3V disk battery. Device dimensions: light guide - ∅8 mm; length 70 mm. Optoelectronic unit in a container: ∅30 mm, height ≈20 mm, weight ≈ (30-40) g. The resource of the device is ~ 800 irradiation procedures, 5 min each.

The use of a PHOTOTHERAPEUTIC DEVICE FOR TREATMENT AND PREVENTION OF RESPIRATORY DISEASES OF THE UPPER RESPIRATORY TRACT IN YOUNG CHILDREN AND ADOLESCENTS will significantly reduce or completely eliminate the use of antibiotics in the treatment of mild and moderate acute respiratory infections.
