Description

The technical field to which the utility model relates.

The invention relates to devices for inspecting, operating and facilitating photography and video recording under artificial lighting conditions with protection from external sources of light in relation to the device, in particular, to medical diagnostic equipment and products used in forensic science, where it can be used to study skin cover for the detection of pathologies and prevention of skin diseases, in forensics - to detect traces of blood, urine, saliva.

State of the art

Luminescent illuminators are known, such as OLD-8M diagnostic luminescent illuminator (see product passport on the website http://www.medrk.ru/uploads/doc/lampa_vuda_old-8m_ps.pdf). 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 "glow" in the medical literature) that occurs during 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.com/text.asp?2004/70/2/131/6915). The disadvantage of this type of 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 power supply network with a voltage of 220 V, in particular, in the passport of a luminescent diagnostic OLD-8M lighter, the voltage of the AC mains voltage is 220 ± 5 V A drawback is that when using them, taking photographs is difficult: in order for fluorescence to be clearly visible, photographing must be done without using additional light sources , this makes it difficult to focus and degrades image quality due to the fact that 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 ; transl. from English. - M.: Publishing house "Good book", 2013. - 213 p., 22-34 p.).

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 are either not equipped with ultraviolet lamps of the spectral range, or do not provide protection from external light sources and fixation relative to the patient during examination without immersion systems, since, according to the technique, it is contactless (see Dermatoscopy in clinical practice. Manual for doctors. Potekaev NN, Shuginina E.A., Kuzmina T.S., Harutyunyan L.S. MDV, Moscow, 2010, pp. 1-50; a description of the devices on the official website of the Heine company http://www.heine.com/ PRODUCTS / PRODUCT-OVERVIEW / Dermatoscopes, on the official website of Dermlite http://dermlite.com/collections/all.

Known devices equipped with lighting systems that allow you to inspect the test object with protection from external sources of illumination in relation to the device without using a dark room, such as RDS (Russian dermatoscope Sergeeva, patent for the invention: "Dermatoscope", RU 1359572, 03/17/2011, IPC A61 B 5/00 (2006.01), A61B 5/103 (2006.01)). This invention is the closest analogue and prototype of the proposed utility model. A “dermatoscope” (referred to in the medical literature as RDS) allows inspection with a polarized light source 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.

Also, the device does not have devices to protect against penetration of rays from external sources of illumination when operating (manipulating) in the field of view.

Disclosure of a utility model.

The objective of the utility model is to create a device that allows inspection and operation (manipulation) in artificial lighting conditions with protection from external sources of light to the device, using at least two lighting systems with the ability to turn on each of the lighting systems independently having a mount for collaboration with the camera, when photographing allows you to fix the position of the camera relative to the object of study at the time of shooting, capable of providing inspection without working together with a computer and without connecting at the time of inspection to external sources of electricity, but having a connector for connecting to an external power source and having an adapter for connecting to an external power source. The device should allow the replacement of elements in contact with the object of study (for example, when working with contagious objects of study).

The technical result is the ability to perform actions in the field of view of the device while maintaining protection against the penetration of rays from external light sources.

To do this, the shading case must be made of light-protective (lightproof) material, lighting systems in an amount of at least two must be attached to the inner surface of the body, the energy source must be connected to the lighting systems, at least one of the lighting systems must be compatible with the light source ultraviolet spectral range, each of the lighting systems must be equipped with a switch.

The shading case has two free edges. The free edge from the side of the observer should be equipped with a mount (hereinafter referred to as “rear mount”) for connecting to a device for photographing or filming in the form of a thread for connecting to the front end of lenses, adapters, by at least one of the manufacturers of cameras, lenses, adapters. This thread can be used to connect to SLR cameras, cameras and video cameras with threads for screwing on the front (facing the subject of the shooting) end of the lens, as well as for connecting with adapters used to connect compact cameras with devices with a threaded connection.

To fix the attached devices for photographing and video recording, the edge of the shading case from the side of the observer should be equipped with two fasteners for soft clips (by the type of belts and tapes) and attached to the fasteners for soft clips by soft clips (by the type of tapes or belts of soft material) for fixing the device to the camera or camcorder, due to the fact that the soft mount can be first attached with one edge (end) to the mount on the device, then tightly wrapped around the camera, or video camera and then another free edge is again attached to one of the device mounts.

The edge from the side of the object of observation should be equipped with a mount for a nozzle for operation (manipulation) (hereinafter referred to as "front mount").

The operation nozzle must be made of opaque material, have a mount for connecting to the front mount of the shading case, must have a hole on the side of the object of observation and cutouts (cutouts of the operation nozzle) in an amount of at least one on the side wall. To reduce the ingress of rays from light sources external to the device, a shading sleeve should be placed in the area of each cutout of the nozzle for operation. The shading sleeve should be made of opaque material, with one edge it should be fixed around the cutout of the nozzle for operation (this part can be made of any soft opaque material), the other edge is not fixed (free edge), the free edge has a hole made of elastic material, tightly fits the tools used, or the hands of the researcher.

In order to avoid contact of the device with the object of observation, a protective removable layer can be used. To fix it on the inside and outside of the nozzle for operation, fastenings for the protective removable layer should be placed. First, the protective removable layer is attached to the inner surface of the nozzle, then, through the opening of the cut-out of the nozzle for operation, or through the hole of the edge of the nozzle for operation, facing the object of observation, it is transferred to the outer surface, partially covers it and is fixed with the mount located on the outside nozzles for operation.
