Cycle type medical dynamometer is fully automated so that brake torque and seat height can be set automatically and settings and measurements, including blood oxygen concentration, recorded automatically

摘要

Medical dynamometer (1) comprises a frame (2) with foot pedals (5) linked to a braking device (6) that is controlled using a control unit (29) that adjusts the braking torque. A patient using the dynamometer sits on a saddle (3) and pedals against the braking torque while blood oxygen concentration is measured using a monitoring device (35). Blood oxygen concentration is measured using an infrared light barrier that passes through a body part such as a finger so that oxygen content in the blood of a capillary can be determined. Optionally if the blood oxygen level falls below a threshold value an alarm can be sounded.
