Description

The utility model relates to the field of medicine and biotechnology and can be used to transport various biopsy material with or without transport media, followed by homogenization.

The active implementation of laboratory and, in particular, microbiological research methods in various fields of medicine, with a significant distance from the collection site and the research base, sets the task in the direction of creating universal transportation systems. The importance of preserving and transporting biomaterial at the initial temperature of taking the material develops various alternatives and proposals in the segment of laboratory transport devices. When using standard transport containers (with or without transport media already entered), the question arises of using additional temperature-saving devices, or the use of expensive container devices with an autonomous temperature storage system (Patent RU 2487687 C1) [1].

The disadvantages of these container devices are a significant increase in the cost of delivery, the use of special devices that require processing, and the need for recharging from electric power sources.

An additional problem is the lack of the possibility of mechanical homogenization and grinding of biomaterial directly in the container, subject to biological safety and maintaining the integrity of the container walls. Thus, it is necessary to create conditions for the transportation of biopsy material, which make it possible to maintain its temperature, tightness, ensuring biological safety, the possibility of using transport media, and also, if necessary, homogenizing the material for further microbiological research.

There is an invention related to universal packaging and / or packaging in the form of a plastic container with a round inlet and a lid, which can be used for medical, household and domestic needs, for example, for transporting biomaterial for subsequent analysis for diagnostic purposes. The container contains a housing with a nose and a cover made with a lateral sealing wall, which is inserted when installed in the cavity of the housing with the overlapping of the nose and the possibility of rotation (prototype) [2].

The disadvantage of this device is the inability to homogenize the biomaterial directly in the container, subject to the requirements of biological safety and the efficient implementation of the stages of preparation of the biomaterial for laboratory research, as well as the lack of thermal insulation of the biopsy material during transportation.

The purpose of creating a utility model is to develop a container for transportation under isothermal conditions and homogenization of biopsy material for microbiological studies. This goal is achieved as follows.

Brief description of the drawing. On the drawings attached to the description is a diagram of the design of the container for transportation in isothermal conditions and homogenization of biopsy material for microbiological studies.

In the drawing of Figure No. 1, the following positions are indicated: 1 — cap, 2 — thread on the bottle, 3 — air gap, 4 — inner contour of the container with a semicircular bottom, 5 — bottom of the outer contour for stability on the surface, 6 — jumper for attaching the loops, 7 -carving on the cover.

Implementation of a utility model. The proposed version of the container for transportation under isothermal conditions and homogenization of biopsy material for microbiological research, consisting of two parts (container and lid). The container consists of external and internal circuits. The outer contour of the container is made in the form of a cylinder with a height of 55 to 55.06 mm and an outer diameter of 31 to 32.04 mm. The inner contour is 48 ± 0.02 mm high and the outer diameter is 12 ± 0.02 mm (position 4 in Figure No. 1). An air gap forms between the inner and outer contours, providing temporary isothermal conditions during transportation (position 3 in Figure No. 1). The external and internal contours of the container are tightly soldered to each other with the help of "jumpers" (position 6 in Figure No. 1). The container is equipped with a thread (position 2 in Figure No. 1) which provides a connection to the lid (position 1 in Figure No. 1) to ensure tightness and biological safety conditions in the closed position, which prevent spilling, evaporation of contents during transportation or accidental capsizing of the container. The outer diameter of the bottom of the container for transportation under isothermal conditions and homogenization of biopsy material for microbiological studies (threaded) from 55 to 55.06 mm. The bottom of the outer contour (position 5 in Figure No. 1) ensures a stable position of the container on the surface. The main material for the manufacture of the container is polypropylene 21060-16, premium grade GOST 26996-86. Allowed the use of polystyrene GOST 20282-86. LOXAMID OA SPEZIAL sliding additive is introduced into the main material in an amount of 0.2-0.5% of the total polymer mass to facilitate the movement of parts relative to each other.

The lid of the container for transportation in isothermal conditions and homogenization of biopsy material for microbiological studies (position 1 in Figure No. 1) is made in the form of a cylinder with a height of 18.9 mm to 19.1 mm, an outer diameter of 57.1 mm to 58.3 mm and an internal diameter of 52.9 mm to 53.1 mm. The inner diameter of the lid of the container for transportation under isothermal conditions and homogenization of biopsy material for microbiological studies on threads from 56 to 56.06 mm. The lid is equipped with a thread (position 7 in Figure No. 1) to ensure tightness in the closed position and to ensure biological safety that prevents spilling, evaporation of contents during transport or accidental tipping of the container. The lid of the container is made of styrene copolymer MSN-L GOST 12271-76. Allowed the use of polystyrene GOST 20282-86. Before casting, add a LOXAMID OA SPEZIAL brand slip additive to the granulate.

The utility model allows expanding the possibilities of transportation and temporary storage of biopsy material in isothermal conditions, ensuring the biological safety of the contents of the container, and also, if necessary, homogenizing the biomaterial directly in the container.

In addition, the proposed utility model allows to reduce the use of tubes for transportation, homogenization and temporary storage, which reduces economic losses in the case of preparatory stages of microbiological examination of biopsy material.
