Description

The utility model relates to the field of medical technology, namely to protective equipment, and is aimed at improving the safety of medical and auxiliary personnel during the transportation / transportation of infected patients with respiratory failure, as a mechanical barrier to the spread of infected particles.

At present, the most urgent problem is to solve the problem of isolating medical and auxiliary personnel from a patient infected with a viral infection that does not belong to the class of especially dangerous infections (DOI), such as plague, cholera, smallpox, yellow fever, anthrax, tularemia. A viral infection is understood as the middle and severe stage of the course of diseases such as influenza, SARS, coronavirus. With a disease, a person is a distributor of these diseases by airborne droplets, which is one of the ways in which viral infections spread. But at the same time, this category of patients needs a number of preventive medical manipulations, such as, for example, intubation during transportation, in which it is necessary to control the correct location of special medical equipment in the patient's head and, if necessary, maintain the correct operation of this equipment, or elementary isolation during transportation with conventional ambulance crews who do not have expensive and massive means of isolation.

Known transport insulating box MED-MOS (https://med-mos.ru/transportirovochnyj-izoliruyucshij-boks-med-mos, manufacturer - the company "Medtekhnika MOSCOW", Russia). The box is a mobile device made of thermoplastic polyurethane and is designed for the safe transportation of patients during a pandemic and in emergency situations. Boxing is a reliable means of biological and chemical protection, which creates a reliable barrier between the internal and external environment and provides a high level of safety for both the patient and others. The device has two modes of operation, depending on the type of tasks. In the positive pressure mode, the box prevents the penetration of hazardous agents into the capsule space. Serves as a reliable protection against external influences for people with weakened immune systems. In negative pressure mode, it prevents pathogenic microorganisms from entering the environment. Allows you to protect medical personnel from infection during the transportation of a seriously infected patient. The product is completed with filter cassettes and protective gloves, which exclude direct contact with the capsule when opening.

However, this insulating box has a number of disadvantages: it is very expensive equipment; is intended for isolation of patients infected with especially dangerous infections (EOI), in milder cases, its use is not justified because of the high cost and bulkiness; depends on electricity (power supply from vehicles or batteries); power supply from vehicles through the cigarette lighter may not be sufficiently reliable and safe; battery life - 5 hours, which may not be enough when transporting over long distances, taking into account traffic congestion; 4 people are needed to carry; limited to a longitudinal dimension of 195 cm.

The closest is Mobile medical box for intubation of infected patients (RU 203495 U1). The body of the box is made in the form of an irregular trapezoid with two holes for hands in the front wall of the body and one hole in the side walls of the body, all holes are equipped with valves, which are made of three sheets of round polypropylene film, each sheet has four cuts through its center , dividing it into 8 identical segments, and the sheets are connected to each other with an offset of 30-35 degrees relative to the center so that the segments of the next sheet overlap the slot of the previous one, and the valve is attached over the hole for the hands using a clamping ring with three bolts, while still three bolts are screwed into the case from the inside and act as guide pins, a stiffening rib is located in the back of the case, and on the side walls of the case there are handles made of PET-G plastic by 3D printing. The entire body of the box is made of plexiglass of different thicknesses: cover - 2 mm, front wall - 5 mm, stiffener and side walls - 8 mm. The proposed medical box provides reliable isolation of medical personnel during intubation / extubation of the patient from abundant splashes of saliva and sputum. The part of the patient's body placed inside the box is isolated from the environment with a medical napkin or sheet.

However, the well-known box is not intended for transporting infected patients and there is no tight fit of the cover to the medical stretcher cart.

The technical result of the claimed utility model is the creation of a mobile medical box for transporting infected patients with a protective cover with a snug fit to the stretcher cart.

The technical result is solved by the fact that the box body is made in the form of an arch with one hole in the front wall, and in the upper part of the box and on the sides there are stiffening ribs, and on the side walls of the body there are holes for attaching handles made of PET-G-plastic by the method 3D printing, through which a belt is threaded, allowing the box to be attached to a medical couch, the box is equipped with a protective cover and has the shape of an isosceles trapezoid, which is attached to the body with studs threaded through the eyelets and fixed to the box with wing nuts, into the seams free from the body The covers are sewn in chains, which ensure a snug fit of the protective cover to the medical stretcher trolley.
