Comfortable load unit

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.


Stable construction, individual configuration

The infinitely variable seat offers an optimal sitting position for patients between 120 and 210 cm height. The handlebar can be adjusted. The easy passage between handlebar and seat is especially helpful for elderly and handicapped patients. The comfortable seat corresponds to the latest developments of touring saddles in the bicycle industry. It might be useful to install differently shaped saddles for different purposes (e.g. pulmonary function examinations with athletes, rehabilitation etc.) For this reason, the saddle pipe is equipped with a standardised saddle fixation to enable easy mounting of all commercially available saddle models. The stable steel-aluminium construction of the ergometer frame and the drive mechanism easily supports a weight of up to 160 kg.


User-friendly control centre

The computer-controlled electronic high-end control centre is situated in the measuring head of the sana bike 450F. 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.


Comprehensive ergometry for cardiopulmonary diagnostics

The modern, processor-based electronic control of the sana bike 450F is designed to allow all common operational modes of the stress test load control. Frequent or regular ergometry measurements can be automated by means of easy programming functions. The user is guided through all operational steps on the display. The ergometer can also be accessed and controlled from an external PC program or ECG unit via the RS232 or USB interface.In this case, the ergometer does not have to be operated separately, as it is fully controlled by the master device’s program. In every mode, the LCD display shows the current load and, if set, the heart rate in an alphanumeric field as well as a graph to view the ergometry status.

The sanabike 450F is equiped with a precise, interference-free blood-pressure unit. This unit measures the systolic and diastolic blood pressures and the heart rate in user-defined time intervals during exercise. Its measuring algorithm is based on the latest trends of blood pressure measurement technology.
