FR2458267A1 - Screen used for clinical photography - is vertical sheet of transparent material with wire grid marked on it for direct reaping of subjects dimensions - Google Patents

Abstract

The screen has a grid marked on it to assist in the interpretation of clinical photographs. The equipment comprises a platform on which the subject stands. The transparent screen is positioned between the subject and the camera and permits the height of the subject to be read directly from the photograph. The grid is made of wire squares and the small size of the squares permits physiological symmetry or asymmetry to be detected. The screen has a device for marking the name and details of the subject which are to be recorded on the photograph.

Description

 The present invention relates to devices making it possible during a clinical medical examination to obtain a photographic image of a subject, highlighting its size, that of its members, its morphological type, the aonformation and possibly the lateral or antero-deformation. posterior of his spine.

 In known devices of this kind the subject was placed between the camera and a blackboard gridded every 5 centimeters. In the photograph obtained, the subject, whose important morphological landmarks had been marked with a dermographic pencil, masked the grid of the painting on which he was projecting, limiting the clinical appreciation sought. We could possibly in the photograph obtained "drag a rectangle delplexiglasst'quadrillé "to facilitate morphological reading The grids of the photograph, the painting and the plexiglass had to be exactly the same and overlap just as rigorously, which was impossible to obtain in addition on various photographs with the same rectangle of plexiglass .

 The device according to the invention makes it possible to avoid these drawbacks. In this one indeed, it is possible to obtain a rigorously exact grid of the plan of the photographed subject allowing measurements having sufficient clinical qualities for a rapid screening before engaging in an X-ray examination made possibly necessary and thus avoiding exposure X-rays become useless and expensive for healthy subjects.

 Its easy application in a school environment would lead to the discovery of harmful attitudes which can be corrected because they are still flexible during the growth of the subject.

 The device which is the subject of the invention comprises a floor base (C) on which the subject will stand upright with his feet placed on variable markers according to the desired position.

 A test pattern frame (B) squared with wire (D) sufficiently fine and of a color allowing the contract with the skin of the subject will be fixed vertically on one of the sides of the plinth floor (C). This target frame (B) will have the minimum height (L2) and width (L3) sufficient to allow standing photography of the subject considered. Direct reading on the photograph of the size of the subject will be possible, the vertical uprights of the frame carrying centimeter measurements.

 The necessary marks will be marked with a dermographic pencil on the skin of the subject who may appear on the floor base in the desired position: back, face, profile, inclined.

 The test frame located between the camera and the; subject will project his grid on the subject and the photograph thus obtained will allow direct reading of the markers marked on the subject and the appreciation on the same scale of the morphological equilibria or imbalances.

 The name of the subject and the date of the examination entered by an appropriate means in a corner of the target frame will make it possible to follow over time through successive examinations the evolution and the results of a possible treatment.

 The camera of a current model will be installed in the axis of the target frame at a focal distance (L6) sufficient to take in its field all or part of the subject of interest. The foot supporting the camera can be adjusted to a height (L5) suitable for taking the camera.

 The wire grid can be replaced by a transparent or translucent grid glass but it is preferable in order to avoid diffraction phenomena when taking the photograph.

 The device which is the subject of the invention can be used in all clinical and morphological examinations in the medical field and very particularly in screening examinations in school or occupational medicine, in industry, for artistic works or uses. domestic applications, the most interesting applications being screening for morphological deformations in schools or in occupational medicine.

 As a variant, the test pattern can be directly incorporated into the camera.
