Corival Eccentric
Possibility to train severe cardiac and pulmonary patients with eccentric exercise
Eccentric ergometry or “negative ergometry” is used to train severe pulmonary and cardiac patients. The motor is pushing the crank axle of the ergometer in the opposite direction. The test subject has to resist this workload and keep the pedal frequency at a selected number to get the desired training effect.
The Eccentric Corival is an ergometer with a design like the Corival with a motor next to the usual electromagnetical braking principle. The maximal eccentric workload is 250 watt. The range of target rpm (30-100 rpm) can be customized and adjusted during the training. The eccentric ergometer has safety protections but may not be used without supervision. Besides this eccentric ergometry, this ergometer can be used for normal ergometry as well.
The ergometer is standard equipped with both a 7" programmable control unit and a 3,5" display.
Highlights
Reliable and reproducible stress tests
The experience of professionals who calibrate many ergometers showed that the Lode ergometers are the most reliable across the complete workload and rpm range and still within specifications even after many years of intensive use.
High standards
Lode is a socially and environmentally responsible company. All Lode products are RoHS/WEE compliant and Lode is ISO 9001:2015, and ISO 13485:2016 certified. All medical products comply to MDD 93/42/EEC, incl. IEC 60601-1.
Various test modes
Besides the hyperbolic (rpm-independent) mode that is used most of the time, the standard control unit offers several other test modes, like the fixed torque mode and the linear mode.These modes can be used in both manual and terminal mode.
Q-factor equal to road-bike
The Q-factor of the ergometer is equal to the Q-factor of road bikes, creating perfect training circumstances.

Features
Compatible with ECG and pulmonary devices
The Lode ergometers have digital interfaces and can be controlled easily by all known stress ECG and pulmonary devices available in the world. This is one of the reasons why the Lode ergometers are very popular worldwide.
Extreme low start up load
The extreme low start-up load of 7 watts and the adjustability in small steps of 1 watt make this ergometer perfectly suitable for many different applications. The standard control unit shows multiple ergometry parameters and you can determine your specific default setting and start-up menu.
Low noise
Due to accurate manufacturing and the careful choice of materials the product has an extremely low noise level.
Accurate over a long period of time
The Lode ergometers are supplied with an electro-magnetic braking mechanism of Lanooy (eddy current). The biggest advantage of this braking system compared to a friction braking system is the absolute accuracy and the accuracy over time. Moreover, friction braking systems have more wearing parts.
RS232 connectivity
RS232 ports enable connectivity to most ECG and ergospirometry devices as well as PC's.
Readout of saddle height
The height of the saddle is stepless adjustable and can be read-out on the saddle shaft
Perfect ergonomic position
Improved ergonomic position according to the latest requirements.
Ultra-low step-through
The lowest possible step-through guarantees easy access to the ergometer for all test subjects: a must for people who are not so mobile!
USB connectivity
USB to connect to PC or ECG or ergospirometry products facilitates easy connectivity.
Small adjustment steps
The workload of the Lode ergometers is adjustable in steps of only 1 watt. Depending on your wishes, the test operator or the test subject can adjust the workload. The steps of 1 watt are possible in the manual mode as well as within protocols.

FAQ
The Corival handlebar is adjustable within 0-360 degrees.
The Excalibur Sport's handlebar is adjustable in both vertical (465- 855 mm) and horizontal (229- 600 mm) direction.

Yes, you can use most commercial available saddles. For the Excalibur an easy saddle exchange option is available. Please contact your service coordinator
During Eccentric or negative ergometry you have to resist against a workload produced by a motor instead of an electromagnet, see article prof. Folgering: Effects of positive and negative exercise on ventilatory CO2 sensitivity.
Yes, you can find interface sheets for most common devices on the website at the "interfacing" tab of the product. If your CPET device is not present you can ask us to support you. In most cases we can quickly provide you with a solution.
During heartrate controlled cycling or running, you can determine a maximum heartrate limit. When this limit is reached, the ergometer/treadmill will adjust the workload/speed so the heartrate will stay more or less stable. You can perform a HR controlled test with the standard controller. You can program HR controlled protocols with the controller of the Valiant, Corival, Angio and Excalibur (more heartrate limits in one protocol (per step)), and the LEM (multi control) software module.
Yes, before purchasing, you can order or it can be changed by a service engineer.
Yes the SpO2 results are visible during the rehab session.
The Q factor of a bicycle ergometer is the distance from crank to crank. For the Excalibur the Q factor is simular to a racing bike meaning 147mm (+/- 3 mm).
The Q factor of the other ergometers is a little bit bigger (like a city bike), for the Corival this is 180 mm.
The Q factor of the other ergometers is a little bit bigger (like a city bike), for the Corival this is 180 mm.
The motor turning the pedals backwards is strong. When the patient can't keep up with the target rpm range or moves a foot from one pedal, the motor will continu speeding up de rpm. A supervisor needs to watch when intervention is needed.
Yes, Due to the fact that the scientific research on the spread of Covid-19 is not yet conclusive Lode recommends to disinfect and clean all Lode products and their accessories (cuffs, heart rate belts, SpO2 sensors, handgrips/rails, touchscreens etc) that are in contact with the patient and or the medical personnel with a standard disinfectant as used in the hospital before and after every patient, with attention and care!
Since these agents are sometimes aggressive it might be advisable to check the effect on sensitive surfaces, like cushioning on non-visible areas. Lode will not take responsibility for discoloration due to these agents.
