Description

Field of technology

The utility model is used in medicine and in particular in ophthalmology.

The utility model is designed for personal measurement of ultraviolet radiation.

BACKGROUND OF THE INVENTION

A radiometer [1] is known, which works with an ultraviolet sensor [2]. The measurement data is transmitted from the ultraviolet sensor to the radiometer in which it is processed and displayed.

The known radiometer, due to the conductive connection between the ultraviolet 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, individual exposure time and exposure time. .

Technical essence of the utility model

The task of the utility model is to create a personal ultraviolet dosimeter with small dimensions and weight, autonomous power supply, measuring the ultraviolet load in the area of the visual analyzer, and 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 placed near the eyes to measure ultraviolet radiation in the field of view of a person.

The utility model contains a plastic housing with a lid. The housing has an electronic unit connected electrically to a battery attached to its underside by a contact clamp. There is a communication module in the middle of the upper side of the electronic unit. An ultraviolet sensor module and a flash memory are located on the front of the upper part of the electronic unit. The communication module is electrically connected to the ultraviolet sensor module and the flash memory. There is an ultraviolet window on the upper side of the housing in front of the ultraviolet sensor module. There is an adhesive layer on the underside of the lid.

An advantage of the utility model is that it allows to measure the amount of ultraviolet load, leading pathological changes of the visual analyzer and behavioral habits as a function of the cumulative effect of ultraviolet radiation, exposure time and individual profile of ultraviolet load.

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

Example of implementation of the utility model

An exemplary embodiment of the utility model is shown in FIG. from 1 to 4. The ultraviolet radiation dosimeter contains a plastic housing 1 with a cover 2. In the housing 1 there is an electronic unit 5, electrically connected to a battery 9, attached on its lower side by a contact bracket 10. In the middle of the upper side of the electronic unit 5 there is communication module 7. In front of the upper side of the electronic unit 5 are located ultraviolet sensor module 6 and flash memory 8. Communication

1899 Descriptions to utility registration certificates № 06.2 / 29.06.2018 the ultraviolet sensor module 6 and the flash memory 8 are electrically connected to the ultraviolet sensor module 6. An ultraviolet window 4 is located on the upper side of the housing 1 in front of the ultraviolet sensor module 6. the underside of the lid 2 has an adhesive layer 3 with a protective foil.

The algorithm for operation of the ultraviolet radiation dosimeter is determined by software stored in the flash memory 8, which is not the subject of the utility model. The algorithm allows to control the status, to change the settings and to view the accumulated data in the ultraviolet radiation dosimeter.

The ultraviolet sensor module 6 is integrated and contains photodiodes, an analog-to-digital converter and a digital signal processor. The ultraviolet sensor module 6 measures the parameters of the ultraviolet radiation incident on it through the ultraviolet window 4. Depending on the selected mode manual or automatic, the ultraviolet sensor module 6 performs single or multiple periodic measurements at regular intervals. The measured results are in analog form, converted to digital form and sent to communication module 7.

The communication module 7 is integrated and contains a radio transmitter, an antenna, a non-volatile memory and a RAM microprocessor controller. The communication module 7 periodically sends through the wireless telecommunication channel 11, which is not an element of the utility model, the accumulated data from the measurements for processing, recording and displaying the information from external devices, such as a personal computer or smartphone. In case of temporary interruptions of the connection through the telecommunication channel 11, the communication module 7 stores the data and sends them after the connection is re-established.

The ultraviolet radiation dosimeter, when used, is mounted on glasses or other accessories near the eyes so that the ultraviolet window 4 is in the direction of the field of view. The ultraviolet radiation dosimeter measures the energy intensity, ultraviolet index and cumulative effect of ultraviolet radiation, which determines the individual dose of ultraviolet radiation received, recording information for an indefinite period of time and creating individual ultraviolet curves and profiles of ultraviolet radiation.
