ABSTRACT:
A therapeutic apparatus for promoting deep breathing in a user has an elastic bag capable of expanding and contracting, the bag having an inlet, and a pipe with a bag engaging flange around one end connected to the bag inlet and a normally closed check valve on the one end for preventing air in the bag from escaping when the check valve is closed. The one end of the pipe and the check valve are made of elastic material and the normally closed check valve has the surface engaged with the pipe defined by a spiral cut around the periphery of the pipe, and the valve is operable by bending the pipe to open the spiral cut.
