The sana couch 250 L couch/semi-couch safety ergometer has been developed for use in the cardiology sector. Special safety aspects, e.g. in cases of suspcted cardiovascular disorders, stress test after a cardiac infarction or after bypass operations, and special exercise ergometry applications, such a heart catheter examinations, require the use of a couch/semi-couch safety ergometer. Its use is also recommended for the examination of elderly and disabled patients.
Thanks to the couch's infinite movability (0-45°), it is possible to find the ideal lying position for every patient and examination method. In case of incident, the patient can be moved immediately into a suitable treatment position. The patient's calm position enables high quality ECG presentation and blood pressure measurements. The height is fixed by means of an adjustable saddle, which also prevents the patient from sliding to the side. The patient's comfort is increased by a headrest. Both elements as well as the couch's slope can be adjusted via remote control. The reclining position at 45° is very comfortable. Medical exercise examinations have proven that the performance in this position corresponds to the performance on a bicycle ergometer. Unlike with previous couch ergometers, the pedalling movement of the legs is now identical to the movement on a bicycle ergometer. This is due to the unique design of the pedal crank shaft. This feature eliminates all performance-related obstacles in couch-ergometry.
The speed-independent load is granted by a high-end eddy current brake with computer-controlled torque measurement. This control, together with the ideal centrifugal mass dimensioning, results in a very pleasant pedalling feeling, allowing the patient to fully exploit his or her reserves. The mechanism, consisting of state-of-the art components, runs almost noiseless, even at high speed.
The computer-controlled electronic high-end control centre is situated in the measuring head of the sana couch 250 L. The measuring head’s front-side features the control elements and a backlit graphic high-resolution LCD display. Its side, containing the display, is usually oriented towards the person operating the device. This is why an LED speed display is mounted on the head’s upper side, clearly visibile for the patient. If the device is used in the rehabilitation or training sector, the measuring head can easily be turned around to allow view on the display and control unit.
