Description

A device for inspecting and facilitating photography.

The technical field to which the utility model belongs.

The utility model relates to devices for inspecting and facilitating photography in the ultraviolet spectral range with protection from external sources of illumination in relation to the device, in particular to medical diagnostic equipment and products used in forensics, where it can be used to study the skin in case of detection pathologies and prevention of skin diseases, to detect traces of blood, urine, saliva.

The level of technology.

Known fluorescent illuminators. They are used for examination in the ultraviolet spectral range, luminescent analysis in veterinary medicine, medicine, forensics, to analyze the quality of food and seed planting material, they are also called ″ black light lamps ″, ″ Wood lamps ″. When used for examining patients in medicine, they can detect fluorescence (the so-called ечение luminescence ’in the medical literature) arising from a number of physiological and pathological processes (see Gupta LK, Singhi M K. Wood′s lamp. Indian J Dermatol Venereol Leprol [serial online] 2004 [cited 2014 Sep 20]; 70: 131-5, http://www.ijdvl.eom/text.asp72004/70/2/131/6915). The disadvantage of this device is that the examination must be carried out in a room protected from other light sources (in a dark room), so that the detected glow (fluorescence) is most noticeable, for example, green glow with microsporia with hair damage. In particular, when using the OLD-8M luminescent diagnostic illuminator, according to the product certificate, it is required to darken the room to a level of natural illumination of no more than 10 lux. Another condition for the operation of these devices is the need to connect the device to an external source of electricity with respect to the device, as a rule, to a 220 V. power supply network. Another drawback is that when using them, it is difficult to take photographs and video: in order for fluorescence to be good noticeable in the picture, photography and video need to be done without the use of additional light sources, this makes it difficult to focus and degrades the image quality due to the fact that in such devices conditions you have to use slow shutter speeds when taking photographs (see Light and lighting in digital photography: a professional practical guide for using any kind of light and lighting to create vivid creative photographs / Michael Freeman; translated from English. - M.: Publisher ″ Good Book ″ , 2013 .-- 224 pp., 22-34 pp.). To reduce the movement of the subject and the camera relative to each other, it is necessary to fix the location of the camera relative to the subject. The above-described illuminators providing illumination in the ultraviolet spectral range are not equipped with such devices.

Dermatoscopes are known that can be connected to cameras and fix the position of a camera connected to a dermatoscope relative to a patient due to the contact part of a dermatoscope, for example, Heine dermatoscopes and Dermlite dermatoscopes. But they either are not equipped with ultraviolet lamps of the spectral range, or do not provide protection from external light sources and fixation relative to the patient when examined without immersion fluids, since according to the procedure it is non-contact (see Dermatoscopy in clinical practice. Manual for doctors. N. Potekaev. N., Shuginina E.A., Kuzmina E.E., Harutyunyan L.S. MDV, Moscow, 2010, pp. 1-50; a description of the devices on the official website of Heine. On the official website of Dermlite).

Known devices equipped with lighting systems that allow you to inspect the investigated object with protection from external sources of light relative to the device without using a dark room, such as RDS (Russian Sergeev Dermatoscope) patent for the invention "Dermatoscope", RU 2459572, 03/17/2011, IPC А61В 5/00 (2006.01), А61В 5/103 (2006.01)). This invention is the closest analogue and prototype of the proposed utility model. RDS (Dermatoscope) allows inspection with a source of polarized light in the cross-polarization mode in the visible spectral range, or using unpolarized light in the visible spectral range, as well as using unpolarized light in the ultraviolet spectral range. Protection from other (extraneous, external) light sources is ensured by the device of the device itself. The walls of the device protect the studied area from the penetration of light from external sources. The disadvantage of this device is that to use it you need to connect to a computer, without connecting to a computer, inspection is impossible, since the device does not have a monitor, or a device for inspection without a computer.

Disclosure of a utility model.

The technical result is the creation of a device that allows inspection under artificial lighting in the ultraviolet spectral range with protection from external sources of light to the device, capable of providing a result without working with a computer and connecting at the time of inspection to sources of electricity external to the device, in particular, to an alternating current network, which has a mount for collaboration with the camera, which allows you to fix the position of the camera relative to itelno patient at the time of shooting.

For this, the shading case must be made of light-protective (lightproof) material, the lighting system must be attached to the inner surface of the body, the energy source must be attached to the inner surface

case and connected to the lighting system, the switch must be attached to the outer surface of the case, near the place of its attachment to the case there should be a hole for connecting the switch to the complex, consisting of a lighting system and a power source for the lighting system. The shading case has two free edges. The edge of the shading case from the side of the observer should be equipped with a mount for the camera in the form of a thread for connecting to the front end of the lenses with threads for screwing on the front (facing the subject of shooting) end. The mount thread for the camera must be compatible with the lens of at least one circumference, at least one of the manufacturers of cameras and lenses. In order to prevent light from external light sources in relation to the device from penetrating the study area and so that the device and camera are fixed relative to the subject, the edge of the shading case on the side of the observation object must be leaned against the object of study, for this the length of the shading the housing must be at least the minimum focusing distance of the lens for which it is intended to be connected.

Implementation of a utility model.

The device comprises a shading case (1), a lighting system (2), an energy source for operating the lighting system (3), a switch (4), a mount for the camera (5)

The device operates as follows: the shading case (1) is attached to the free edge of the lens for the SLR camera using the mount for the camera (5), using the switch (4) the lighting system (2) is turned on, the edge of the shading case on the side of the observation object is leaned against the object so that the gap between the object of study and the edge of the shading case is the smallest and the light from sources external to the device does not penetrate the study area. Then, using the monitor or the viewfinder of the switched on camera, examine the studied area and, if necessary, take pictures. If it is necessary to inspect without using a camera, disconnect the camera and the shading case and examine the studied area through the opening of the shading

the case from the researcher’s side (from the side where the mount for the camera is located), tightly leaning the other free edge of the shading case against the object under study.
