ISOLATING BREATHING SELF-RESCUER WITH CHEMICALLY BOUND OXYGEN

摘要

A breathing self-rescuer with chemically bound oxygen comprises the case with the cover, the housing intended for carrying the device with the ears for attaching the locking device containing two coupling strips with locking appliances designed as the bar with the hooks for the ears at the ends of the strips and as the square-topped bar with the hooks in one of the strips and two-arm lever in the second strip contacting by the smaller arm with the hooks of the square-topped bar with the seal and the wire passed through the openings of the square-topped bar and the lever. The device also contains the regenerative cartridge with oxygen-containing substance, the breathing bag with the pressure-relief valve, the facial mask with the corrugated tube, the nasal clamp and the mouth-piece, the actuator with the starting cord over the cartridge, and the additional belt attached to the cartridge. For improving the operational conditions of the device due to simplification of the design, the carrying devices are made demountable representing the flat T-shape bar with the groove along the axis of the symmetry with the attaching device above representing L-shaped flat spring. The carrying device is attached to by its larger part the bar with the connected C-shaped eye for the waist belt. The bar is located in the longitudinal grooves on the sides of the housing with the flexed free end of the attachment element being in the groove on the end-face of the cover.
