Abstract

Device for macroscopic photographs of anatomopathological specimens of small size, consisting of a white interior box that allows to place inside a container of black interior inside which is centered and stabilized on a metal ring the sample to be photographed, immersing it in alcohol. Four light sources located on the floor of the box allow to illuminate it diffusely. The inner black circle of the lid and the hole in its center allow to avoid the appearance of reflections on the surface of the alcohol. Once the device is mounted with the part inside it, photographs can easily be taken by supporting a mobile phone on the limpet and placing the camera in its hole.

Description

DESCRIPTION

Device for macroscopic photographs of small pathological specimens

Technical sector

Clinical diagnosis. Pathological anatomy. Photography

Background of the invention

The Macroscopic study of the surgical pieces that are sent to the Pathological Anatomy laboratory is the first approach to diagnosis. Obtaining quality images of these pieces allows you to conveniently document cases for your study, for publication or for presentation for clinical, teaching or research purposes.

The pathological specimens of small size (for example: eyes, ovaries, thyroid ...) allow the taking of macroscopic images that encompass the entire structure.

In the daily clinical practice the following problems occur: the lack of professional photography mechanisms in many laboratories, or their complicated access or use: in many cases the photographs are taken with the mobile phone, so that its quality is altered by the perspective given by the position of the phone and by the tremor if it is held by hand.

Immersing the specimens in alcohol improves the color and contrast of the photographs, but on the surface of this liquid there are reflections of the illumination of the laboratory, the camera or the hands of the photographer.

Explanation of the invention.

The technique we propose below allows:

1. - Stabilize the pathological specimens so that they do not move and remain motionless during the photographic process.

2. - Present them on a dark background that improves the contrast of their structures.

3. - Dip the specimen in alcohol to improve its appearance (color and texture).

4. - Illuminate specimens with diffused and indirect light.

5. - Avoid reflections on the surface of the alcohol, coming from the lighting, the photographer or the camera.

6. - Stabilize the camera on the zenith axis of the piece avoiding tremors and image distortions.

The device is designed to be used with the camera of any mobile phone.

Brief description of the drawings

To complement the description that is being made and in order to help a better understanding of the features of the invention, it is accompanied as an integral part of Said description, a set of drawings where, for illustrative and non-limiting purposes, the following has been represented:

b. - You can see the inside of the device cover with a black circle centered in the hole for the camera.

Preferred Embodiment of the Invention

The device consists of a box with the white interior, with a lid that can be easily removed and replaced. In the center of said cover there is a hole that should be sufficient for the size of the camera of a mobile phone. Inside the box, on its floor, four light sources are placed. To facilitate the centering of the specimen, the center of said floor is marked with an "X". A black hemispherical container is placed in the center of said "X." A metal ring is placed in the center of the bottom of this container. 2 cm in diameter (it should not float in alcohol) The anatomopathological specimen that will be perfectly stabilized will be placed on the ring, then the container should be filled with alcohol completely covering the piece.

The inside of the lid of the box must also be white, except for a circle painted black whose center will be the hole for the chamber and whose diameter must be greater than that of the inner hemispherical vessel.

The white walls of the box diffusely reflect the light, avoiding the reflection of the light sources on the surface of the alcohol, and the black circle inside the lid prevents reflections on the surface of the alcohol.

The mobile phone rests on the outer surface of the case, matching the camera with the central hole, which coincides with the zenith axis of the specimen, so that perspective distortions and tremors are avoided, and it can be easily zoomed.

The invention is susceptible of industrial application, due to its simple design and handling, and the potential interest of its use in any pathology laboratory.

Claims (13)

1. Device for macroscopic photographs of pathological specimens of small size characterized in that it comprises: - A box open at the top (figure 1-b) - A cover that can be put on and taken off (figure 1-a) - Four light sources (figure 1-c) - A hemispherical vessel (figure 1-d) - A metal ring (figure 1-e) 2. Device according to claim 1 characterized in that the box has sufficient height to house the rest of the integrating elements, allowing the lid to close properly. 3. Device according to claim 1 characterized in that the inside of the box is white so that the light is reflected in a scattered manner. Device according to claim 3, characterized in that the center of the floor of the box is indicated by an "x" for the correct centering of the specimens (Figure 2a). 5. Device according to claim 1 characterized in that it has a cover with the white interior to reflect the light in a scattered manner. 6. Device according to claim 5 characterized in that in the center of the cover it has a hole of sufficient diameter to be able to take pictures with the camera of a mobile phone (Figure 2b). 7. Device according to claim 5 characterized in that inside the lid there is a black circle centered the central hole, to avoid reflections on the surface of the alcohol (figure 2b). 8. Device according to claim 1 characterized in that on the floor of the box there are four light sources located in the four corners, leaving the center of the floor free (Figure 2a). 9. Device according to claim 1 characterized in that a hemispherical container whose interior is black is placed in the center of the floor of the white interior box (Figure 2a). 10. Device according to claim 9 characterized in that the hemispherical container must be filled with alcohol so that the photograph of the specimen is taken with this submerged in its entirety. 11. Device according to claim 1 characterized in that a metal ring two centimeters in diameter is placed in the center of the inner floor of the hemispherical vessel (Figure 2a). 12. Device according to claim 11, characterized in that the pathological specimen is placed on the metal ring, which is thus stable inside the hemispherical vessel. 13. Device according to claim 1 characterized in that once the specimen is placed on the metal ring, inside the hemispherical container, filled with alcohol, and closed the lid, a mobile phone with camera is supported on it, so that this it is placed over the hole and through it the photographs are taken on the zenith axis of the piece avoiding tremors and distortions.
