UA116198U - CONTAINER FOR OBJECTS OF BIOLOGICAL ORIGIN - Google Patents

Abstract

The container for objects of biological origin contains a cylindrical body with upper and lower threaded lids. In the case in a separate additional compartment, separated from the main compartment by a perforated partition, a desiccant is placed; the lower cover is made of transparent material for visual inspection of the dehumidifier, and the upper cover has a toothed clamp for fixing the object.

Description

The useful model belongs to the means of forensic technology and is intended for the preservation of traces of biological origin, which are removed from the scene.

In the work practice of forensic units, the task of preserving traces of biological origin removed at the scene often arises, which include traces of blood, semen, saliva, traces of sweat and fat, hair, as well as bones, parts of human organs and tissues (including particles of nails, skin, etc.).

Traces of biological origin at the scene are usually detected in the form of microparticles (drops, stains, smears, etc.) on the surfaces of various objects, clothing and the human body. Such traces and objects are removed from the scene during its examination for the purpose of further forensic investigations, therefore their proper preservation is extremely important for establishing the truth in criminal proceedings.

A common method of preserving biological traces is to pack them in paper bags and then seal them. The use of waterproof polymer bags that prevent air circulation is not allowed. Wet objects or tangible evidence, which are carriers of traces of biological origin, are pre-dried at room temperature in a darkened room. Each removed object is packed in a separate paper bag. The disadvantages of using paper bags are the need for preliminary preparation (drying) of samples and their insufficient protection against moisture from atmospheric air.

Along with this, various test tubes and containers intended for medical and laboratory purposes (storage of blood tests, urine, etc.) are also used in practice. For example, as part of a universal set for work at the scene of an event ESKTO0A ZEAKSN 3-Ogamzheg/5iogade Emidepse

SoiPesiop Kii of the American company 5igspie includes 6 types of cans and containers of different capacities (per/lumlmu.vitspiv.sot/rgodisiv/emidepse-soPesiiop-iooi5-Kiiv/emidepse-soiPTesiop-Kyiv/zeagsp-3- dgaumeg-5iogade-eymidepse-soPesiop- KI. pitiy. 4 m7ySx9R'). Hermetic properties of these containers do not allow storing wet samples for a long time due to the decomposition processes of the latter.

For storing samples that require drying or staying in an atmosphere with

With a given level of humidity, desiccators are widely used (P.I. Voskresenskyi Tehnika laboratornih rabot. - 10th edition, stereotyped. - M.: Chemistry, 1973). A desiccator is a cylindrical vessel made of thick glass or plastic. The desiccator is closed from above with a lid, the surface of which joins with the body is lubricated with a special substance to achieve tightness. The desiccator has a special shape, with a narrowing in the lower part, which allows you to place the desiccant substance on the bottom, and above it to install a lattice porcelain tray on which samples or boxes and crucibles with samples are placed.

However, desiccators are intended for use in laboratories and cannot be used in the field due to their large dimensions and unsuitability for transportation.

The useful model is based on the task of creating a container that allows for the storage of extracted substances and other biological objects, as well as small objects that carry traces of biological origin, including wet ones, and also provides for the possibility of its reliable sealing for the prevention and detection of cases unauthorized opening.

At the same time, the design of the container should be simple, cheap and provide for its multiple use. The solution to this problem is achieved due to the original design of the container and the use of common materials.

The task is solved by the fact that the container for objects of biological origin, which consists of a cylindrical body with upper and lower threaded caps, which is distinguished by the fact that the indicator substance-desiccant is placed in the body in a separate additional compartment, separated from the main compartment by a perforated partition ; the lower cover is made of transparent material for visual control of the condition of the desiccant, and the upper cover has a toothed clamp to fix the object.

Drawings explain the essence of a useful model.

In Fig. 1 shows the general view of the container, and Fig. 2 - its section with the main structural elements. The container consists of a cylindrical body 1, an upper threaded cover 2 and a lower threaded cover 3. The inner cavity of the body is divided into two compartments by means of a perforated partition 4, one of which (main) is intended for storing the extracted traces of biological origin, and the other (additional) - for placing the desiccant. A square rod 5 is attached to the inner surface of the upper cover 2, at the end of which there is a toothed clamp for holding the selected object. As a desiccant, a mixture of ordinary and indicator granulated silica gels is used.

The lower threaded cover 3 is made of transparent material, which allows you to visually monitor the condition of the desiccant substance (humidity level).

When preparing the container for use, the additional compartment is filled with a desiccant substance and the lower lid is screwed tightly. The cylindrical surface of the housing in the place of its connection with the lower cover is sealed, for example, with a special adhesive tape or tape, on which information about refueling with a desiccant (date, name of the responsible person) is applied. When using the container during the inspection of the scene, the lid of the main compartment is unscrewed, to which a biological object or an object bearing traces of biological origin (for example, a fragment of filter paper with traces of blood) is placed directly or with the help of a toothed clamp, which must be removed for further examination . After that, the cover is twisted and the cylindrical surface at the junction of the body and the top cover is sealed. For sealing, a special multi-layered sealing adhesive tape (sticker) can be used, for example "Secure-Yit" (Original seal (vesyhe-yi) - pyrzi/Lymly.rietkiIv.de/gy/tadagip/ ogidipaI-paia-riotbra-5ek-ishck -y-5esyge-y.pti). Such a protective sticker provides protection against unauthorized opening of containers.

The possibility of air flow between the compartments of the case through the perforated partition ensures the process of drying the sample during storage and prevents the development of the decomposition process of biological substances. The possibility of subsequent sterilization of the container body and lids ensures their multiple use.

This device provides: reliable and long-term storage of objects of biological origin due to the use of a desiccant; reliable and high-quality sealing of the container during use; - humidity control; multiple use of the container.

This device can also be used in the medical field for the selection and preservation of samples from various objects with subsequent analysis and research; in the field of food technologies during sampling during product certification; in the emergency service when conducting fire-technical studies and examinations.
