Description

The utility model relates to devices for ensuring biological safety during the transportation of pathogenic biological agents (PBA) and is intended for use in medical, veterinary, agricultural profiles in research, diagnostic and medical institutions.

Pathogenic biological agents - pathogenic bacteria, viruses, chlamydia, rickettsia, fungi, mycoplasmas, genetically modified microorganisms, toxins, helminths, as well as any objects and materials, including field, clinical, sectional ones, containing / suspicious for the contents of the listed agents - must be contained and transported in a container kit or kit that provides individual and public biological safety (Safety of work with microorganisms of I-II pathogenicity (danger) groups; San final rules. SP 1.3.1285-03, Safety of work with microorganisms of pathogenicity groups III-IV and helminths. Sanitary rules. SP 1.2.731-99; Procedure for recording, storage, transfer and transportation of microorganisms of I-IV pathogenicity groups. Sanitary rules. SP 1.2.036-95. - M .: Goskomsanepidnadzor of Russia, 1996).

The basic requirements for a device for transporting pathogenic biological agents should be as follows:

- ensuring biosafety during transportation and storage;

- providing the ability to transport a different number of different-sized containers with pathogenic biological agents;

- the use of durable materials for the manufacture of containers for transportation: metal - for pathogenic biological agents of groups I-II, metal or plastic - for groups III-IV.

Numerous universal containers, cases, wardrobe trunks, sets, and piling for the collection, storage and transportation of biomaterial are known.

Known thermal container for storage and transportation of biomaterials (Application for invention No. 96109396, 07.27.1998). An adjustable thermal container for storing and transporting biomaterials contains a thermally insulated body with a lid and containers with a cold-containing substance. The housing with the cold-containing substance consists of several composite blocks, the boundary between the blocks passing between the slots for ampoules. The container with a cold-containing substance is made in the form of a rectangular or other shape of the case with the outside open

nests for ampoules (packages) with biomaterial, which enter the case and directly contact with the cold-containing substance.

However, the described container does not meet the requirements for the transportation of pathogenic biological agents.

A device for transporting pathogenic biological agents is known, comprising a tightly closed or screwed case in the form of a pencil case made of metal or plastic, a hermetically sealed container installed in the case. The interior of the housing contains hygroscopic material for sorption of the liquid in case of damage to the container (Transport of infectious substances. - WHO, 2004). Cases have structural elements for sealing. The disadvantage is the inability to accommodate and transport a large number of hermetically and non-hermetically sealed containers of various sizes with pathogenic biological agents, for example, when working in emergency situations caused by accidents, natural or environmental disasters, epidemics, epizootics, epiphytotics, and the act of bioterrorism.

The technical result of the claimed utility model is to ensure the biological safety of personnel and the environment during transportation of various amounts of different-sized containers with pathogenic biological agents in accordance with the requirements for the transport of infectious materials, as well as the safety of samples for laboratory diagnosis. In addition, the use of an adsorbent with a moisture indicator allows you to visually determine the fact of a leak of a material containing pathogenic biological agents as a result of violation of the integrity of the containers; locking and sealing elements prevent unauthorized access to pathogens; the use of an autoclavable transport bag ensures safety and simplifies the preparation for disinfection of the ingredients and components contained in it after removing containers with pathogenic biological agents from the bag at the destination; the proposed constructive solution provides compactness during transportation.

The essence of the utility model is to achieve the specified technical result by the proposed device.

A device for transporting pathogenic biological agents consists of many containers interconnected by fasteners in a single unit. Each container contains a housing with a lid installed in it with the possibility of forming an inner enclosed space by an autoclavable transport bag containing modular partitions and / or supports with

lodgments for different-sized containers. In this case, the space between the containers, as well as between the containers and the inner wall of the bag, is filled with an adsorbent with a humidity indicator.

The container body is made of solid, shockproof, water and gas impermeable materials, resistant to chemical disinfectants and physical disinfectants. The container body may be made of metal or plastic. On the side surfaces of the housing in the upper part on both sides are handles for easy transfer. The use of a belt secured to these handles for carrying by one person is also provided.

Modular partitions for the formation of niches / sections for laying, protecting and fixing containers with PBA of any configuration are made of light, disinfected materials, such as aluminum, plastic, corrugated cardboard. They are designed to exclude the possibility of moving containers and violating their integrity during transportation.

The support with lodges is a rigid structure and made of autoclavable material at a temperature of at least 132 ° C, for example, aluminum wire, plastic. At the end ends, it is equipped with handles for easy removal from the box. The stand is designed to transport large containers, bottles with screw caps for sampling water with a volume of 500 ml or more.

The adsorbent contains granules of the indicator, which, when absorbed by the adsorbent of water (from 20%), change color. It is possible to use silica gel as an adsorbent with a moisture indicator produced by SPL LLC. The indicator is made of biologically safe organic materials. Its blue granules, upon absorption of water, change color to pink or light purple, and then become colorless. The adsorbent is designed to absorb liquid in case of material leakage in case of violation of the integrity of the tanks with PBA. The amount of adsorbent introduced into the autoclavable transport bag is calculated based on its absorption capacity.

If it is necessary to observe a special temperature regime during transportation, the space between the inner walls of the container and the autoclavable transport bag is filled with refrigerants or heat transfer agents.

On the surface of the container, a visual system of symbols is made, which includes three elements of information. On one of the side surfaces of the container, the first and second information elements are applied. The first element of information is made in the form of a pictogram - an international sign “Biological

danger! ” The second element of information is made in the form of a pictogram - the international sign “Infectious substance”. The third element of information is applied on the side surface and on the upper side (lid) of the container and is made in the form of a pictogram and a written notice indicating the correct vertical position of the cargo - the international handling sign "Do not turn over!"

The container is equipped with a lock and an element located in the lock and intended for applying a seal.

On the front and rear sides of the container, two pairs of fasteners are provided, for example, locks-brackets, which allow connecting several containers into a single device, thereby ensuring a strong fixation and compactness during transportation. Depending on the working conditions and the tasks to be solved, it is possible to connect containers of the same size or of different sizes.

The essence of the utility model is illustrated by drawings, where

Figure 1 shows a General view of the device.

Preparing the device for transportation.

Material containing / potentially containing pathogenic biological agents selected for transportation is placed in airtight and leakproof containers (9). Hermetically sealed containers are represented by sealed ampoules and test tubes, sealed vials, sealed tubes of thick glass or plastic material, as well as test tubes, closed corks and sealed with various plasticizers (Procedure for recording, storing, transferring and transporting microorganisms of I-IV pathogenicity groups. Sanitary rules. SP 1.2.036-95. - M .: Goskomsanepidnadzor of Russia, 1996). Leak-tight containers can be represented by disposable and reusable cups, test tubes, bottles, bottles with screw caps, transport systems (containers with transport media), tubers, special transport containers with anaerobic environment, (Collection and

transporting biomaterials to microbiological laboratories. MU 4.2.2039-05). Capacities are marked.

An autoclavable transport bag (7) is placed in the container (1) so that it lines the interior, repeating the contours. An adsorbent with a moisture indicator (11) is poured onto the bottom of the bag with a thin layer. Separate containers or containers mounted in tripods and stands are placed in a bag. To pack large containers (bottles, bottles) in a bag, a stand with lodges is installed on the adsorbent layer (10). All containers are separated by modular partitions made of flexible materials (corrugated cardboard, aluminum, plastic), forming niches / sections inside the bag (8). After that, the remaining adsorbent with a moisture indicator is introduced into the space between the containers and partitions. The total amount of adsorbent placed in the stack is calculated based on the absorption capacity of the product used and the volume of all the material that must be absorbed in case of leakage. For example, when using silica gel (100 g absorb 40 ml of liquid) for packaging 6 bottles with water samples from water bodies of 500 ml each, 7.5 kg of adsorbent should be placed in a container. After filling, the air is removed from the bag, sealed with a cloth tape, tightly tied over the tucked edge, forming an inner enclosed space. Accompanying documents with the list and the number of containers with PBA are attached to the bag. In order to preserve PBA for laboratory diagnostics, in some cases, during transportation of the material, special temperature conditions must be observed. To do this, use refrigerants or heat transfer agents that are placed in the space between the bag and the walls of the container. The container, after filling the entire volume, is tightly closed with a lid, locked (2) and sealed (3). To carry out sealing through the provided holes in the upper and lower parts of the lock, the twine is passed and the ends are connected with a seal. In this form, it is ready for transportation. Subsequent containers are similarly equipped. Then the containers are mounted on top of each other and fixed between themselves by fasteners (6).

Upon arrival at the destination, the containers with PBA are removed from the autoclavable transport bag. The bag and its accessories and ingredients (modular partitions, stand, adsorbent) are autoclaved and disposed of as household waste. In case of repeated use, they must be dried. Silica gel type adsorbent is calcined in a muffle furnace at 180 ° C. for 10 hours. The inner and outer surfaces of the container are decontaminated by regulated methods (Safety of work with microorganisms of groups I-II

pathogenicity (danger). Sanitary regulations. SP 1.3.1285-03; Safety of work with microorganisms of the III-IV pathogenicity groups and helminths. Sanitary regulations. SP 1.2.731-99).

The utility model provides biological safety, protecting personnel and the environment from infection during transportation and disinfection of infectious material, provides compact placement of containers during transportation, is convenient to use, and saves preparation time for departure to complete assigned tasks.
