Part number: 960903
Corival Pediatric
Easy accessible and approachable for children

The special design of the Corival Pediatric guarantees easy access and ergometry testing of children. The ergometer is standard supplied with a communication module and can therefor be easily controlled by all known stress ECG and pulmonary devices in the world. The workload, rpm and time can be readout from the 7" colour display. The Corival has an eddy current electro-magnetic braking mechanism. The biggest advantage of this system is the accuracy which is one of the most important Lode principles. With this ergometer, the stress tests performed are reliable and reproducible. The workload is adjustable in a range of 7 to 1000 watt.


A USB A-B cable for service purposes as well as connecting to ECG and pulmonary testing devices will be standard delivered with the product.To connect older ECG and pulmonary testing devices with RS232 or other connectors you need a special interface cable that can be ordered separately.

Overview

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 9001:2003, ISO 13485:2008 and FDA 510K certified. All medical products comply to MDD 93/42/EEC, incl. IEC 60601-1.
Rotatable handlebar
The handlebar can be rotated 360 degrees and is constructed in such a way that the test subject can sit comfortably at every seating height. This design makes a height-adjustable handlebar redundant.
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.
Multifunctional
The ergometer can be used in various ergometry settings, enabling a multifunctional deployment.
Features
Child friendly design
The special design of this ergometer makes it easy accessible and approachable for children.
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.
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.
Service friendly
Service friendly ergometer
Lode ergometers are very service friendly. In general, total costs for spare parts are so low that they are negligible. Furthermore, most options are so easy to install and firmware is so easy to update that labor costs are minimal. Moreover, the ergometer can be cleaned easily.

FAQ

Q - In what range are the handlebars of the Corival and Excalibur adjustable?

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.

Q - Is it possibe to estimate the travelled distance?

This is possible for all ergometers from 2004 on. Since 2009 it is possible to create yourn own calculation by using the adjustable resistance. Note: both pedalling speed and workload are taken into account by estimating the travelled distance.

Q - What is Eccentric ergometry

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.

Q - Is it possible to control the Lode ergometers and treadmills with external equipment

Yes, you can find interface sheets for most common devices on the website at the "service" tab of this website. If your device is not present you can ask us to support you. In most cases we can quickly provide you with a solution.

Q - What is the principle of the Heart rate option?

The HR option is the well known Polar* heart rate receiver. The receiver is integrated in the software of the controller. The test subject has to wear the heart rate belt around the chest. The receiver is placed in front of the test subject (or integrated in the controller in case of a Corival) and the HR data will be displayed on the controller of the ergometer

Q - What is heart rate controlled cycling / protocol?

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.

Q - What is the 0 Watt start up system?

The 0-Watt start-up system is an option for the Corival and Excalibur ergometers. It offers the opportunity to start the ergometer at a preset pedal speed (30-80 rpm). The number of revolutions is increased from 0 to the desired rpm by means of a motor drive. With this option there is no energy-loss for the test subject due to the start-up phase. The motor has to be built-in in the ergometer during manufacturing. Example: before starting the test the ergometer must be set at the lowest workload (7 watt), or a protocol must be selected with a first step of 7 Watt (max 10 Watt). When pushing the 0-watt button, the number of revolutions is increased to the required pedal speed. Release the button and the ergometer will have a workload of 7 watt. The test subject does not have to overcome the initial resistance of the braking mechanism and can start the test with the lowest workload at the required rpm in the normal rpm-independent mode.

Q - Is it possible to turn the display around so it is facing the physician?

Yes, before purchasing, you can order or it can be changed by a service engineer.

Q - Is the SpO2 option compatible with LCRM?

Yes the SpO2 results are visible during the rehab session.

Q - Is it possible to request RPM and Load data through the RS232 port while cycling in Manual mode.

Yes you can request the actual pedalling speed and power when you are cycling in Manual, Analogue or Terminal mode.
The load will only be returned when the pedalling speed is 30 RPM or more. For technical details see the Lode RS232 protocol

Q - Can I use a RS232 to USB converter to connect an ergometer?

Yes you can. Make sure the chipset used in the converter is from FTDI to have good data acquisition.
Not sure what this means? Contact us and we will help you to get the right converter.
