RU7588U1 - FIRST-AID KIT - Google Patents

Abstract

1. A first aid kit comprising a body in the form of two chambers with lids and locks, characterized in that one of the chambers is made heat-insulated and is equipped with a thermoelectric battery coupled with a radiator. 2. A first aid kit according to item 1, characterized in that the thermoelectric battery is installed on the rear outer surface of the heat-insulated chamber and is connected to a power source via an electric plug-converter.

Description

The utility model relates to devices intended for placement and storage of medicines.

It is known that the storage of many drugs requires a low temperature and the absence of light. In clinics, pharmacies and other medical institutions, medicines are stored, as a rule, in refrigerated cabinets, and at home - in domestic refrigerators. A simple, compact and reliable device for storing medicines in medical posts, gyms, campsites, traffic police posts, etc. no.

There is a known first-aid kit, the closest in technical essence and the achieved result to the claimed utility model, containing a case in the form of two chambers (parts) with covers and locks, the chambers being interconnected by a shell and made folding, and the locks have an original design.

see A.S. USSR, N 372991, M.C. A 47 B 67/02, declared 02/03/71., Publ. 03/12/73. , 6.

A well-known first-aid kit does not provide the possibility of lowering the temperature during storage of medicines and, therefore, increasing the life of their use.

FIRST-AID KIT

- 2

The objective of this utility model is to create a refrigerated first-aid kit of a simple and reliable design that ensures long shelf life of medicines.

The problem is solved in that in a well-known first-aid kit containing a case in the form of two chambers with lids and locks, ACCORDING TO THE USEFUL MODEL, one of the chambers is thermally insulated and equipped with a thermoelectric battery paired with a radiator.

The thermoelectric battery is installed on the rear outer surface of the insulated chamber and is connected to the power source through an electric plug-converter.

Analysis of the known technical solutions allows us to conclude that the claimed utility model is not known from the level of the technology being studied and, therefore, meets the criterion of novelty.

The possibility of manufacturing the proposed first-aid kit at domestic enterprises from commercially available structural elements allows us to conclude that it meets the criterion of industrial applicability.

The figures schematically depict the inventive First Aid Kit. Figure 1 is a front view (first aid kit is open). Figure 2 is a side view (first aid kit is closed). designations in figures:

1- upper heat-insulated chamber (cold);

2- lower chamber;

3- covers of the upper and lower chambers;

4- locks;

5- thermoelectric battery;

6- radiator;

7- electric plug-converter.

The inventive first-aid kit consists of a housing made in the form of an upper heat-insulated (item 1, figure 1) and a lower chamber (item 2, figure 1). moreover, the volume of the upper chamber is 2 l, the lower is 3 l. Both chambers can be made of aluminum or food grade plastic.

The first-aid kit has mainly the following overall dimensions, mm:

-height - 400;

-width - 280;

-depth - 120.

Thermal insulation of the upper chamber, for example, polyurethane foam, glass wool or other similar material. The cameras have covers (pos. 3, fig. 1) and locks (pos. 4, fig. 2).

Thermoelectric battery (5, 2) is installed on the rear outer surface of the upper thermally insulated chamber and consists of

- 3

- 4 Peltier elements (not shown in the figures). A thermoelectric battery (pos. 5, Fig. 2) is interfaced, for example, with a needle radiator (pos. B, Fig. 2). The thermoelectric battery is connected to the power source by means of an electric plug-converter (pos.7, Fig.2). The power source can be alternating current (voltage 220 V) or direct current (voltage 12 V). Both chambers are closed by covers (pos. 3, fig. 1) using locks (pos. 4, fig. 2). The proposed first-aid kit works as follows. Medicines that do not require cooling were placed in the lower chamber (item 2, figure 1), where they were stored at room temperature. Medicines requiring cooling were placed in the upper isolated chamber (item 1, figure 1). The cameras were closed with covers (pos. 3, Fig. 1). using locks (item 4, figure 2). After that, the plug-in converter (pos. 7, Fig. 2) was connected to a power source (for example, to an AC power socket with a voltage of 220 V). At the same time, using the developed surface of the needle radiator (pos. B, figure 2), paired with a thermoelectric battery (pos. 5, fig. 2), the upper thermally insulated chamber (pos. 1, fig. 1) was cooled at a speed of 0.5 ° C / min, until the temperature in the chamber stabilizes in the range of b-10 ° C. The use of the claimed First-aid kit in comparison with the known, taken as a prototype, see A. USSR N 372991, provides the following equipment

- 5 social and socially useful advantages: -stabilization of temperature in a cold chamber in the temperature range b-10 ° С; -simplicity and reliability of the design (warranty period 2 years); - increase the shelf life of drugs by cooling the environment in a cold chamber; - ease of placement and operation due to compactness and low weight (not more than 1.5 kg); -extending the scope of application (the possibility of use in domestic and industrial premises, first-aid posts, gyms, campsites, traffic police posts, car interiors, etc.) -low electrical consumption (not more than 20 W).
