Abstract: A health appliance comprises a fitting member fittable in between toes or fingers and having in an interior thereof a pressurized medium charging portion. This portion is expanded in a direction so as to widen a space between the toes or fingers when the pressurized medium is charged therein. A pressurized medium charging port is provided at a location of the health appliance so as to communicate with the fitting member, for charging the pressurized medium into the pressurized medium charging portion.

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.

Abstract: An apparatus is provided for use in deep breathing exercises and includes a bag capable of expanding and contracting, a pipe connected to the bag for allowing air to be blown into the bag, and a check valve provided at an outlet hole of the pipe. At least the air outlet hole of the pipe and the check valve are formed of an elastic material so that the air collected in the bag can escape when the check valve is opened by elastically deforming the pipe adjacent the air outlet hole and the check valve, and so that the escape of the air is stopped when the check valve is closed due to elastic return of the pipe and the check valve. Accordingly, opening and closing of the check valve can be easily carried out so that deep breathing to improve health can be mastered irrespective of age or sex.
