FIELD: medical equipment.SUBSTANCE: self-contained breathing apparatus using chemically combined oxygen is designed for respiratory protection in emergency situation and comprises a body of film, in which there is placed a regenerative product in the form of reinforced plates. Body is made of separate sections, connected in parallel to the insulation join, and each section is additionally equipped with shutoff element installed on the inlet and outlet of each section. Shutoff element is made up of thermosetting film, produced by tensile deformation of film of ftoroplastic F-4 MB. Between the sections there is installed thermal insulation.EFFECT: invention provides uniform working off of plates of the regenerative product, thereby reducing the weight of the device, reducing breathing resistance and increase usability of use of self-contained respiratory apparatus both in working position, and carrying.7 cl, 8 dwg |
