Description

The utility model relates to medical equipment, in particular to devices for transporting and storing a corpse, cadaveric material, biologically hazardous objects.

Known sanitary cover (RU 2114593 [1]), consisting of the top, containing made along the entire length of the device closing and opening, bottom and side panels, the transverse sides of the bottom and top panels are made combined.

The disadvantage of the known device is the lack of tightness, which reduces the scope.

Closest to the claimed technical solution is a sealed container with odor protection for the remains (US 5659933 [2]), including a sleeve made of composite material, welded at the ends of the sleeve.

The known device has an increased tightness compared to [1] due to the integral soldering of the walls.

The disadvantages of the composition include insufficient reliability due to insufficient thermal stability of the material.

The technical result is an increase in reliability due to an increase in thermal stability.

The technical result is achieved by the fact that the hermetic package (for transportation, storage of a corpse, cadaveric material, biologically hazardous objects), including a blank made of composite material, welded along the edges with a transverse seam, is characterized by the fact that the film of the package contains 4 layers, counting from the outer: 1 - thermal varnish, 2 - polyethylene terephthalate (PET), 3 - foil, 4 - medium pressure polyethylene (PSD).

The film may have a total thickness of 220-230 µm, which will provide sufficient strength at the required cost.

The seam can be made with a manual sealer at a temperature of 200°C for 3-4 seconds, 10 mm wide, which will increase reliability and strength due to the optimal strength of the seam. At the same time, the thermal varnish, the top layer of the film, does not allow the underlying layers to be burned under the temperature of the sealer. In the experiment, the film completely burns out at temperatures above 500°C. The film does not release toxic substances into the environment and does not have a harmful effect on the human body upon direct contact, which is not unimportant for workers of morgues and ritual services during constant work and contact with the film. Working with it does not require special precautions.

Metallization can be made of aluminum, which will increase reliability due to the low gas permeability of aluminum.

Implementation of the utility model

In FIG. 1 shows the arrangement of the layers of the hermetic bag, FIG. 2 - a package blank with an unfolded edge for clarity, where

1 - thermo varnish;

2 - polyethylene terephthalate;

3 - foil;

4 - medium pressure polyethylene;

5 - weld;

6 - sealed side of the package;

7 - open side of the package;

8 - inner surface of the lower film;

9 - the inner surface of the upper film.

The blank of the film has straight edges, the outer layer consists of a thermal varnish 1, under which there is a layer of polyethylene terephthalate 2, under which there is a foil 3 and an inner layer of medium pressure polyethylene. The ends of the film, when exposed to temperature during soldering, are pressed against each other, forming a seam 5. The bags are made and stored individually. For sealing bodies, packages are used, in the manufacture of which two adjacent sides 6 are sealed, the other two 7 remain open. For clarity, the inner surface of the lower film 8 and the inner surface of the upper film 9 are shown. This design allows you to effortlessly place a body of any size without technical difficulties in a bag, and then the remaining two sides are sealed.

A package made of a metallized protective film is airtight when sealed, prevents the spread of an unpleasant odor, leakage of liquid, and the release of biologically hazardous contaminants. Transmits x-rays. Burns at high temperatures. It is used to transport corpses with signs of decay to the place of burial / cremation.

To contain the spread of dangerous and especially dangerous infections, including Covid-19, Ebola, etc. by sealing the bodies of those who died from such infections.

Tightness, density, high strength of the package, air and moisture impermeability, throughput for X-rays allows the transportation of the bodies of the dead by air transport, as well as over long distances by ground transport without additional galvanized boxes. At the same time, the weight of one package is not more than 1500 and at a price 3 times cheaper than zinc coffins and galvanized boxes.

Thus, the package is a unique substitute for a zinc coffin. The body is placed in a bag, hermetically sealed and placed in a regular box for transportation. Such a package replaces a heavy expensive zinc coffin, saves time on manufacturing, manipulations for its sealing and desoldering.

The use of bags is possible in order to contain the spread of especially dangerous zoonotic infections (anthrax) for transporting the bodies of dead animals to the place of burial / cremation.

The possibility of burning the package allows it to be used in crematoria without opening them and extracting the bodies of dead people, animals and other biological objects.

The dimensions and weight of the package allow the body, closed in such a package, to be placed in a coffin to create the aesthetics of a funeral procession.

The production of bags allows you to adjust the size depending on the size of the biological object placed in it.

The difference from polyethylene pathoanatomical bags lies in its tightness and high strength, at many stages of transportation, evacuation it can completely replace it, while the bag restrains the spread of an unpleasant odor, leakage of liquids, and the spread of infectious agents. While the polyethylene pathological bag does not meet such requirements. The use of a bag instead of a pathoanatomical bag makes it possible to classify a bag made of a metallized film as a medical device.

Properties of the metallized film

Breaking force of a welding seam longitudinal 98 N/15 mm.

Breaking strength of the welding seam transverse 89 N / 15 mm.

Penetration strength (impact strength) 150 N.

Elongation at break in the longitudinal direction 378 N/mm ² .

Elongation to break in the transverse direction 437 N/mm ² .

As a sealer, a constant heating manual sealer such as FKR-200, 300, 400 made in China or others can be used. Given the high tensile strength, opening the package is possible only with the use of sharp objects (scissors, knife, etc. objects).

EFFECT: increase in efficiency is achieved in its tightness and high strength, at many stages of transportation, evacuation it can completely replace it, while the package restrains the spread of an unpleasant odor, leakage of liquids, and the spread of infectious agents. The use of a bag instead of a pathoanatomical bag makes it possible to classify a bag made of a metallized film as a medical device.

Industrial Applicability

The proposed package can be made using well-known technologies and used for transportation, storage of a corpse, cadaveric material, biologically hazardous objects.
