MINE RESCUE DEVICE Russian patent published in 2017 - IPC A61G1/00 

FIELD: rescue works.

SUBSTANCE: mine rescue device refers to the means of transport and evacuation of the wounded and injured as a result of emergency situations, especially in mine workings, when carrying out rescue operations in a limited space, and then transporting the injured. The mine rescue device includes a gas-tight air-filled shell-chamber with fixing elements, means for injecting the working medium with a pipeline, the gas-tight air-filled shell-chamber is made in the form of a series of cylinders communicating with each other and located perpendicular to the longitudinal axis of the gas-tight air-filled shell of the chamber. According to the invention, the medium injection means is made as gaseous medium discharge and emptying sources, a series of cylinders is made in the form of truncated cone-shaped sections with a variable surface curvature geometrically variable within each section, the fixing elements being shifted relative to each other under the outer surface of the gas-impermeable air-chamber, and the pipeline connects the cylinders working cavities and is made in the form of a filling pipeline and an emptying pipeline, which through the inlet and outlet valves located on them are connected respectively with the gaseous medium discharge and emptying sources.

EFFECT: simplified manufacturing technology of the device with orientation to typical operations of filled soft shells by fabricated rubber products plants, increasing the device reliability and in case of emergency assistance, evacuation of the injured in sparing conditions, delivery to the day surface in the event of elimination of possible injuries during lifting.
