Abstract
Systems, devices, and methods for providing a feedback signal to assist a patient in repeating a breath-hold at the same point in successive respiratory cycles. The tracking device includes: a spring-biased wheel; a strap configured to wrap around a patient and having a segment configured to wind around a portion of the wheel when the patient exhales, and to unwind when the patient inhales; and a processor configured to detect an angular position of the wheel and to present the patient with a corresponding feedback signal.
Claims20
A respiratory tracking device comprising:
- a spring-biased wheel;
- a strap configured to wrap around a patient and having a segment configured to wind around a portion of the wheel when the patient exhales, and to unwind when the patient inhales;
- and
- a processor configured to detect an angular position of the wheel and to present the patient with a corresponding feedback signal.
A method of facilitating a breath-hold event at a predetermined point within a respiratory cycle, comprising:
- providing a strap configured to wrap around a patient and having a segment configured to wind around a portion of a spring-biased wheel when the patient exhales, and to unwind when the patient inhales;
- providing a processor configured to detect an angular position of the wheel;
- and
- presenting the patient with a feedback signal corresponding to the angular wheel position.
The method of claim ii, further comprising:
- converting the angular position of the wheel into the feedback signal using a transducer.
The method of claim ii, wherein presenting the feedback signal comprises displaying at least one of a graphical, audible, and haptic indication of a breath-hold set point.
A respiratory set point tracking device, comprising:
- a belt configured to extend around a patient and engage a spring-biased wheel;
- and
- a transducer configured to convert an angular position of the wheel into a haptic feedback signal.
