Description

The utility model relates to the field of medical equipment, namely, portable thermal containers for storing, transporting medicines, pharmaceutical substances, biologically active additives, parapharmaceutical, cosmetic products and their active substances / substances, as well as other non-medical products requiring compliance and temperature control within strictly specified limits.

Known thermal container (RU No. 108025, class B65D 81/38, published September 10, 2011), including a detachable composite case, a lid and a bottom made of flexible (foamed) thermal insulation material, covered on the outside with a single fabric cover with incomplete ring fasteners zippers located on the side surface of the cover. The components of the housing include a cavity for the container with the product, and at least one cavity for heat and cold elements, which are separated by at least one mesh partition sewn around the perimeter in the cover. One zipper is located on the wall of the cavity for the product container, the bottom of which is a mesh partition, and the other is at the edge of this cavity with the possibility of folding part of the cover with the cavity for heat and cold elements.

A disadvantage of the known thermocontainer is the inability to control the temperature and maintain the required temperature inside the cavity for the product container, which makes it impossible to temporarily store during transportation of thermosensitive biomaterials.

Closest to the claimed device is a thermal container for storing and transporting biological products (RU No. 2495340, class F25D 3/14, F25D 11/00, publ. 10/10/2013), comprising a body of thermally insulating material with a cover and thermal accumulators installed with an air gap between the walls of the housing, as well as the working chamber with thermal insulation and a cover with a seal. The working chamber is made with the possibility of alternating air exchange with the environment or cavity between the walls of the housing and the inner chamber through ducts with integrated valves that are connected to a temperature sensor, bellows or bimetallic spring located in the inner chamber. The set temperature is maintained in the thermocontainer by means of valves opening and closing functionally related to the temperature, through which cooled air from the thermal accumulators enters the inner chamber when the temperature rises above the set temperature or, when the temperature decreases, warmer air from the environment.

A disadvantage of the known design of the thermal container is the lack of an accurate measurement of the temperature inside the housing at a particular point in time. An increase in the temperature of thermal accumulators to ambient temperature during long-term storage or transportation can lead to changes in the properties of biological objects that require maintaining thermal conditions within strictly specified limits. In addition, the design is quite complicated to manufacture.

The problem of the utility model is the development of a simple and reliable design of a thermal container that provides storage and transportation of biological objects at a given temperature regime from 2 to 8ºС due to temperature control inside the working chamber.

The technical result of the utility model is to simplify the design.

The indicated problem and the claimed technical result are achieved in that the thermal container includes a body of thermally insulating material with a lid, a working chamber and thermal accumulators. According to a utility model, an integrated temperature sensing unit with a temperature sensor is additionally mounted in the walls of the container of the thermal container, the recording end of which is moved outside the walls of the container body into the working chamber. The walls of the working chamber are formed by thermal accumulators, conjugated with each other at the edges.

The case of the thermal container is made of rigid polyurethane foam.

Thermal accumulators are made mainly in the form of a rigid rectangular hermetic frame.

It is advisable to carry out thermal accumulators on the basis of “Safepack MAX” and / or “Safepack PLUS” of the PCM class.

The recording end of the temperature sensor is located between the edges of adjacent thermal accumulators

The installation in the case of the thermal container, for example, in the cover, of an integrated reading unit with a temperature sensor, the free end of which is outside the container cover inside the working chamber, allows maintaining the optimal temperature regime due to the possibility of adjusting the temperature measurement inside the thermal container, and also reacting to temperature changes in time by placing the thermal container in the required temperature zone.

The implementation of the working chamber of the composite thermal accumulators based on "Safepack MAX" or "Safepack PLUS" PCM class placed in the housing provides an increase in the duration of passive maintenance of a given temperature regime for storing biological objects during their transportation.

The use of thermal accumulators of the largest possible size minimizes cold bridges, and the tight arrangement of thermal accumulators to each other ensures a reduction in thermal convection, and, consequently, increases the time for maintaining the optimum temperature regime.

The implementation of the thermal accumulator in the form of a rigid rectangular frame eliminates direct contact of the heat-accumulating substance with the product.

The execution of the housing made of rigid polyurethane foam, which has low thermal conductivity and high thermal insulation properties, allows you to maintain optimal temperature conditions and simplifies the installation of an integrated reading unit with a temperature sensor in the walls of the housing during its manufacture.

The utility model is illustrated by drawings, where in FIG. 1 shows a general view of the thermal container, in FIG. 2 - the cover of the thermal container, in FIG. 3 is a three-dimensional image of a thermal container in an exploded isometric view.

The thermal container includes a housing 1 made of thermally insulating material with a cover 2, a working chamber 3, and thermal accumulators 4. The housing 1 is made of rigid polyurethane foam with high thermal insulation characteristics and increased impact strength. An integrated reading unit 5 with a temperature sensor 6 is installed in the lid 2 of the thermal container, the recording end of which is outside the lid 2 of the container inside the working chamber 3. At the same time, the working chamber 3 is formed by thermal accumulators 4, conjugated to each other at the edges. The working chamber 3 is located inside the housing 1. Thermal accumulators 4 are stacked close to each other, forming a closed temperature box. The recording end of the temperature sensor 6 is located between the edges of adjacent thermal accumulators 4.

Thermal container works as follows.

Thermal accumulators 4, cooled to a temperature of 5 ° C, are placed in the housing 1 of the thermal container with the formation of the working chamber 3. Inside the working chamber 3 there is biological material that must be stored or transported for a certain time at a temperature of 2 to 8 ° C. In the case of cargo transportation in this thermocontainer at an ambient temperature of 35 ° C, with information from the integrated reading unit 5 from the temperature sensor 6 that the temperature inside the working chamber 3 is 7.5 ° C, i.e. approaching the maximum allowed, the thermal container with the load is moved to a temperature zone not exceeding the value of 8 ° C or replace the thermal accumulators 4 with a temperature (5 ° C). This operation allows you to prevent the temperature inside the working chamber 3 from exceeding the set temperature range.

The thermal container is easy to manufacture and can be manufactured using known technologies. The container is currently undergoing pilot testing.
