Definitions
- the invention relates to a chemical oxygen device according to the preamble of the claim 1.
- Chemical cartridges for breathing apparatus are known in the prior art. Such a chemical cartridge is described in DE-C-26 35 376. In this version, this is limited by an upper and lower space Chemical from the exhaled air through a forehead and lateral surface of the chemical volume flows through and passes as breathable air through a circumference with holes provided central tube in a breathing bag.
- the particle filter is immediately on Inhalation valve arranged.
- Inhalation valve arranged for devices based on the principle of pendulum breathing work (DE-A-41 37 331), an additional heat exchanger is necessary. Leading this means that when the user inhales, the filter and / or heat exchanger resistance must be overcome.
- the invention is based on an embodiment shown in the drawing explained in more detail.
- the figure shows a schematic representation of an embodiment of the chemical oxygen device according to the invention.
- the chemical cartridges (2) are on the exhalation side with a breathing bag (3) for the Exhaled air connected, at the input of an exhalation valve (5), in which a Fan (8) and on the wall of a pressure relief valve (11) is arranged.
- On the inhalation side are the chemical cartridges (2) with a breathing bag (7) for the Inhaled air connected, at the entrance of a particle filter (6) and at the Output an inhalation valve (4) is arranged.
- an energy source (10) e.g. a battery or a Accumulator arranged.
- the operator of the chemical oxygen device according to the invention requires exhalation only overcome the breathing resistance of the exhalation valve (5). Overcoming the breathing resistance of the chemical cartridges (2) and the Particle filter (6) takes over the blower (8), which for the first time in chemical oxygen devices is used.
- the conditions of use of the chemical oxygen device according to the invention are further improved by the evaluation unit (9), which is available at all times Indicates the supply of breathing gas.
- the display can e.g. through the evaluation the device parameters of the fan (8) and the resulting one Consumption of chemical takes place in the form of the remaining stock.
