Problems solved by technology

However, vibrations cannot be completely avoided by this method because the pleated mesh insert is not spatially stable and can be displaced in the chemical cartridge
Difficult or impossible to evenly fill filter cartridges with particles
However, the respiratory physiology can be more significantly limited after the aforementioned mechanical loading

Embodiment Construction

[0051] The breathing apparatus for oxygen generation includes a breathing bag 1 made of a sealing material, a chemical filter cartridge 2 sealed and fixed in the opening of the breathing bag 1 , and a breathing hose 3 with an interface 4 and a nose clip 5 . The breathing hose 3 is integrally connected to the receptacle 6 enclosing the upper area of ​​the chemical filter cartridge 2 , whereby the chemical filter cartridge 2 is sealed and fixed in the breathing bag 1 by the holder 7 . In inactive use, the breathing apparatus is assembled in a stable sheet metal container, preferably secured to the user's belt. When the wearer of the breathing apparatus finds himself in an environment with unbreathable gas or smoke, he opens the packaging container and inhales and exhales via the interface 4 . CO contained in breathing air 2 with the KO contained in the chemical cartridge 2 2 The particles react to generate heat to generate oxygen, which enters the breathing bag 1 through an op...

Abstract

The invention relates to a respiratory protection device wherein the chemical cartridge through which inhaled air flows in order to produce oxygen is subdivided into a plurality of air treatment compartments (15 to 18) by means of retaining gratings. The outer air treatment compartments (15, 18) are provided with fine copper braid shock-absorbing means (21a, b) that rest flat against the respective cover. The center air treatment compartments (16, 17) are provided with a concertina-folded damping element (24, 25) from a multilayer fine braid having fold edges that extend in parallel and at a distance to the outer wall of the chemical cartridge (2). The one - zigzagged - edge of said damping element is fastened to a wire grating (26, 27). The damping elements of adjacent air treatment compartments are not aligned. The air treatment compartments accommodate potassium peroxide granules (22) for producing oxygen. An air treatment compartment (18) can be filled with lithium hydroxide tablets (23) for binding excess carbon dioxide. The inventive device is immediately operative at high mechanical stress even when it was not actively used for a long time and has a high output.

Description

technical field [0001] The present invention relates to an oxygen-generating breathing apparatus, which comprises a chemical cartridge (chemical cartridge), through which two-way flow occurs, and the chemical cartridge is connected with a breathing hose and a breathing bag, wherein the chemical cartridge includes A plurality of air treatment chambers separated from each other by a gas-permeable barrier grid, and the air treatment chamber at one end of the chemical cartridge adjoining the counterlung is filled with a chemical that binds carbon dioxide and that is present in particulate form for oxygen production chemicals, placed in other air handling chambers. Background technique [0002] An aerobic breathing apparatus of this type is previously known from US 4,515,156A. It is intended to achieve improved distribution and thorough mixing of breathing gases by dividing the chemical cartridge into chemical processing chambers. Multi-element spacer screens are available for...
