BG112440A - Personal dosimeter for ultraviolet radiation in the visual system - Google Patents

Abstract

The personal dosimeter for ultraviolet radiation finds application in the field of medicine, in particular in ophthalmology. It is intended for personal measurement of ultraviolet radiation in the study of pathological changes in the visual system and behavioural habits as a function of the cumulative effect of ultraviolet radiation. The dosimeter has an electronic unit (5) comprising a communication module (7), an ultraviolet sensor module (6) and a flash memory (8). The communication module (7) is electrically connected to the ultraviolet sensor module (6) and the flash memory (8). The UV sensor module performs single or multiple periodic measurements and the results are sent to the communication module (7), which periodically sends, via a wireless telecommunication channel, the measurement data.

Description

BACKGROUND OF THE INVENTION

A radiometer [1] known to operate with an ultraviolet sensor 2 |. The measurement data is transmitted from the ultraviolet sensor to the radio meter. in which they are processed and depicted.

Blow out and drink a radiometer. due to the wire connection between the \ .tt ravpo.tetovnya sensor and the radiometer. creates difficulties and inconvenience in its use as a personal ultraviolet dosimeter for the effect on the visual analyzer and behavioral habits as a function of the cumulative effect of ultraviolet radiation, exposure time and individual profile at ultraviolet load.

Technical essence of the utility model

The object of the invention is to provide a personal ultraviolet dosimeter with small dimensions and weight, autonomous power supply, measuring the ultraviolet load in the area of the visual analyzer, as the measurement data is transmitted for storage and display on a wireless telemetry channel.

The problem is solved with an ultraviolet radiation dosimeter, which incorporates a battery and a communication module for a telemetry channel and which can be mounted near the eyes to measure ultraviolet radiation in the field of view of a person.

The invention comprises an electronic unit electrically connected to a battery located on its underside. There is a communication module in the middle of the upper side of the electronic unit. In the front part of the upper side of the electronic unit there are an ultraviolet serial fertilizer module and a flash memory. The communication module is electrically connected to the ultraviolet sensor module and the in-memory memory.

An advantage of the invention is that it makes it possible to measure the amount of ultraviolet load leading to pathological changes in the visual analyzer and the behavioral habits Bi.B function of the cumulative effect of ultraviolet radiation, exposure time and individual profile under ultraviolet load.

Another advantage of the invention is that it provides convenience in personal measurement in the field of the visual analyzer of ultraviolet radiation, due to its small size and weight, autonomous power supply and transmission of data for storage and display on a wireless telemetry channel.

Example 5a implementation of the utility model

An exemplary embodiment of the invention is shown in FIG. 1 - 3. The ultraviolet radiation dosimeter contains an electronic unit (1) electrically connected to a battery (5) located on its lower side. There is a communication module (3) in the middle of the upper side of the electronic unit (1). An ultraviolet sensor module (2) and a flash memory (4) are located in the front part of the upper side of the electronic unit (1). The communication module (3) is electrically connected to the ultraviolet sensor module (2) and the flash memory (4).

The algorithm for the operation of the ultraviolet radiation dosimeter is determined by software stored in the flash memory (4), which is not the subject of the invention. The algorithm allows to control the status, to change the settings and to view the accumulated data in the dosimeter for ultraviolet radiation.

The ultraviolet sensor module (2) is integrated and contains photodiodes. analog-to-digital converter and digital signal processor. The ultraviolet sensor module (2) measures the parameters of the ultraviolet radiation incident on it. Depending on the selected manual or automatic mode, the ultraviolet sensor model (2) performs single or multiple periodic measurements at regular intervals. The measured results are in analog form. are converted into digital form and sent to the communication module (3).

The communication module (3) is integrated and contains a radio transmitter. antenna. permanent and RAM microprocessor controller. The communication module (3) sends periodically via a wireless telecommunication channel (6), which is not an element of the invention. the accumulated data from the processing measurements. drink and display information from external devices, such as a personal computer or smartphone. In case of temporary transfer of the connection through the telecommunication channel (6), the communication module (3) stores the data and sends them after the connection is restored.

Doses of ultraviolet radiation can be mounted in Kopnvc in the form of a box closed with a lid, and when used, the housing can be attached by gluing or other means on glasses or other accessories near the eyes. An ultraviolet window located in front of the ultraviolet sensor module (2) must be installed in the housing.

The ultraviolet radiation dosimeter measures the energy intensity, the ultraviolet index and the cumulative effect of ultraviolet radiation, which determines the individual received dose of ultraviolet radiation by recording the information for an indefinite period of time and creating the individual curves and creating the individual curves.
