Scope of application
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.
Infinite movability and adjustability via remote control
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.
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.
User-friendly control centre
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.
Comprehensive ergometry for cardiopulmonary diagnostics
The modern, processor-based electronic control of the sana couch 250 L 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 sana couch 250 L is equipped 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. Alarm limits can be set for the load, heart rate and blood pressure. If these limits are exceeded, an alarm is issued. For heart-catheter examinations, any required load can be set manually.
