Description

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

Currently, the most urgent is the solution to the problem of isolating medical personnel from a patient infected with a viral infection. A viral infection is understood as a medium and severe stage of the course of diseases such as: influenza, ARVI, coronavirus. When a person is sick, he spreads these diseases by airborne droplets, which is one of the ways of spreading viral infections. But at the same time, this category of patients requires a number of medical manipulations, such as, for example, intubation / extubation, in which a burst of fluids from the patient into the environment is possible, which can cause a large percentage of subsequent diseases of the people around the patient, in particular, medical personnel.

If necessary, a box is installed on the infected person and transported around the hospital without fear of infecting other patients and doctors.

However, in the known device, the openings for the hands of medical personnel are located only in one plane - from the side of the head, while operations from the lateral sides are possible, which are impossible in this box.

The technical result of the claimed utility model is the creation of a mobile medical box for the intubation of infected patients, providing reliable isolation of medical personnel during intubation / extubation of a patient from abundant saliva and sputum splashes.

The technical result is solved in that the box body 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, and all holes are equipped with valves, which are made of three sheets of round polypropylene film, in each sheet four cuts are made through its center, dividing it into 8 identical segments, and the sheets are interconnected 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 pressure ring three bolts, while three more bolts are screwed into the case from the inside and act as guide pins, there is a stiffener in the back of the case, and on the side walls of the case there are handles made of PET-G plastic using 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.
