Description
It swings non-stop!
Plastic device containing a valve inside to intercept the return of air, if you stop blowing, when inflating a balloon. Very motivating and rewarding element for those who start in the control of oral expiratory murmur. You can work on air management at different resistances, varying the characteristics of the balloon attached to its end. The package includes a valve plus five balloons of assorted colors of a special thickness so that they can offer more resistance. The “deluxe” valve is differentiated and characterized by superior performance to the conventional non-return valve, as it contains a button or device inserted in the same element to release air when pressed.
Contains: deluxe non-return valve and 5 balloons of assorted colors.
