SU85858A1 - Regenerative Oxygen Respirator - Google Patents

Description

Known reactive oxygen respirators consisting of a mouthpiece with tubes, a cylinder with compressed oxygen, a pulmonary bag, a regenerative cartridge, a reducer with a lung machine, a bypass and a filter used, for example, in mining and rescue operations are heavy and have a heavy gauge. sizes.

In the described respirator, the volume of the pulmonary bag with the elastic tape inside it is more fully used; a light capillary tube was used to connect the high-pressure oxygen cylinder with a finimeter and a lightweight structure (I breathe and expiratory valves of a reduced size; sizes, three preserving other environmental qualities.

FIG. 1 shows a respirator, side view; in fig. 2 is the same view from the front; in fig. 3 shows the upper part of the regenerative cartridge with a cut along the body of the exhaust valve; in fig. 4 - section of the exhalation valve.

The regenerative oxygen respirator consists (Fig. 1 and 2) of the following main parts: rubber 3ary6HHiKa 1, mouthpiece box 2 with two tubes 3, exhalation valve 4 mounted in the body of the regenerative cartridge 5, pulmonary bag 6 with elastic tape 7, moisture box 8 , oxygen cylinder 9 with shut-off valve. 10 valve and connecting pipe 11, gearbox 12 with a lung machine 13, bypass 14 and inhalation valve 15.

Work in a respirator is carried out when taken into the mouth of a rubber mouthpiece. The exhaled air through the mouthpiece 2, one of the tubes 3 and the exhalation clalan 4 enters the regenerative -patron 5, trapping carbonic acid from the exhaled air. Next, exhaled air enters the pulmonary mesh. 6, where "from the air, moisture is collected, captured by vlatosbornik 8 and additional oxygen is produced. Oxygen uniformly enters the pulmonary bag from the balloon 9 through the stop valve 10, the connecting tube 11 and the pressure reducer reducing pressure 12. If the volume of oxygen supplied is insufficient, then the amount of oxygen supplied will be insufficient.

No. 85858.- 4 -

in the pulmonary membrane, due to increased respiration, a vacuum w w is created and the oxygen volume will flow through the lung machine / 5, which is a pressure reducing valve. In the event of a malfunction of any of the oxygen supply devices, the latter can be introduced into the pulmonary room through the manual bypass actuator M. When you inhale, the inhalation rivet 15 opens, and breathable air from the pulmonary sac enters the lungs through the oj th from the tubes.

A feature of the expiration valve device (Fig. 4) is the removable lid-stop 17 installed in the seat body 16; as a result, the mica valve 18 can be easily replaced.

Elastic tape 7 connects the upper movable wall of the pulmonary sac with the fixed lower one. When in, the upper wall has the ability to descend, thus achieving a more complete use of the pulmonary volume. For fuse protection: Nenya I pulmonary from raising the pressure in it above a predetermined value, a safety clamp 19 is installed in it. A finimeter 20 indicating the pressure in the oxygen cylinder 9 is connected to the last capillary tube 21.
