The sana cardio 1000 is based on the technology of the couch/semi-couch safety ergometer sana couch 1000. An additional rotation axis of the couch to the right allows the patient being turned during stress to a left-side position to max. 30°. This position is especially suited for high-quality ultrasound images during a stress echo examination. A hip belt and a stable shoulder support grant the patient's safety and comfortable position whilst the couch is turned to its side.
Besides this special application, the ergometer can, of course, also be used as a normal couch/semi-couch safety ergometer. Special safety aspects, e.g. in cases of suspected cardiovascular disorders, stress tests after a cardiac infarction or after bypass operation, and special exercise ergometry applications, such as heart catheter examinations, require the use of this ergometer. The use of a stress echo couch is also recommended for the examination of elderly and disabled patients.
Thanks to the infinite movability of the couch (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 prove 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 cardio 1000. 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.

|Variable couch||Couch size 90 cm x 55 cm for heights from 140 cm to 205 cm; weights up to 160 kg. The seat and the headrest are adjustable to the patient's correct reclining position via remote controle. A 50 cm wide paper-roll carrier is situated under the headrest.
The couch can be continiously altered from a slope of about 45° (exercise position) to a flat position. The slope is also adjusted via remote controle.To optimize the patient's examination position, the couch can also be turned to the left by up to 30°. A hip belt and a stable shoulder support guarantee the patient's safety whist the couch is being turned to the side.
The arm rest for blood pressure measurement and a handle can be flexibly mounted on the guide rails, located on both sides of the couch.
|Handle as mounting aid||A stable, adjustable handle serving as a mounting aid is located near the head.|
