Lode Corival Paediatric

What makes a Lode Ergometer?

Ever since Freerk Lode manufactured the first electro-magnetic bicycle ergometer in 1952, accuracy, reliability and durability have been fundamental for future product developments. Having started in the market of cardiology and pulmonary function, Lode BV has become the world market leader in Ergometry. Lode’s product range covers the the complete spectrum of medical ergometry.

The eddy current electro-magnetic braking mechanism is synonymous to all Lode Ergometers. Eddy current braking systems offer quiet, smooth, precise and adjustable control. Through design, this allows control of the workload without the need for physical contact between brake pads and the flywheel, reducing wear and tear.

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.

Child friendly design

The Lode Corival Paediatric workload is adjustable in 1 watt increments and in the range of 7 to 1000 watts. This offers a wide working range for test subjects of all strengths and abilities. The communication module built into the Lode Corival Paediatric will easily connect with our range of Cortex Metabolic devices or ECG devices.

The ultralow step-through enables easy access to the ergometer and combined with the easily adjusted handlebar it guarantees a perfect ergonomic position. The saddle height can be read out via the scale on the saddle shaft or digitally, via the optional 7″ touchscreen.

Maximum user weight – 180 kg

Accuracy

Workload below 100w – Accurate within 3W

Workload between 100w – 500w – Accurate within 3%

Workload between 500w – 1000w – Accurate within 5%

Easy to Clean

All surfaces on the Lode Corival Paediatric are easily wipeable thanks to their gloss finish. Use a lightly moistened cloth with a non-abrasive, soap or disinfectant. Cleaning agents containing alcohol or caustic components may damage and/or discolour surfaces.

Hidden Connectors

All cables and connections are underneath the ergometer, reducing the risk of wires accidentally being knocked or pulled out and give a cleaner look.

Display options and features

7″ Touchscreen Control Unit (fitted as standard)

The 7″ Colour Touchscreen enhances the capability of the Lode Corival Paediatric by allowing the ergometer to be used as a standalone piece of equipment in manual mode. The below parameters can be visualised on the 7″ Touchscreen display:

• Actual and target load, alpha or torque
• Distance
• Time
• Energy
• Mode
• Heart Rate (If purchased separately)
• Blood Pressure (If purchased separately)
• SpO2 (If purchased separately)

For full automation of a protocol, the 7″ Programmable touchscreen control unit is recommended.

7″ Programmable Touchscreen Control Unit

The program function enables testing and training on the Lode Corival Paediatric with a controlled change in workload during exercise. Protocols manage the load during exercise in steps, ramps or even a heart rate controlled function without having to change this manually. Defining the protocols beforehand not only provides a controlled workload but also gives room to focus on the test subjects during exercise.

Program stages include:

Step
The workload can be adjusted and the duration of this hyperbolic stage can be determined; the load is
independent of the RPM.

Ramp
The workload (watt) is increased linear as a function of time (proportional protocol). It will take the total duration time to reach the programmed workload.

Heartrate controlled
The workload is regulated as a function of the adjustable heart rate for a certain duration in this heartrate controlled step.

Fixed Torque for bicycle ergometers
The torque in Nm can be adjusted with a certain duration in this fixed torque stage; load P = 2*π*N*T [W] goes linear with cadence.

Linear for bicycle ergometers
The workload is coupled with RPM with constant α as the adjustable parameter for the desired duration; load P = α * N2 [W] goes up with square of cadence.

Recovery
The recovery stage is the last stage of a protocol, the recovery value can be selected as a percentage of the last stage in the [Settings] menu and will have an unlimited duration.

Programming is flexible, you can mix all above types of variables, except recovery which is always the last stage, within one protocol.

Up to 50 protocols can be programmed. For ergometers the predefined protocols are: 20Watt/minute, 25 Watt/minute, Interval 25-75, Hollmann, WHO and Ramp 0-300W.

3.5″ Colour second screen

The 3.5″ Colour second screen is used to display information to the test subject on the treadmill, such as:

• Speed
• Elevation
• Test time
• Heart rate(when available)

Further Options for the Lode Corival Paediatric

Heart Rate

This option gives the heart rate in beats per minute on the touchscreen display and offers the possibility of implementing heart rate controlled protocols. The test person wears a belt with a sensor.

NB this can only be ordered in combination with the (Programmable) 7″ touchscreen control unit.

Blood Pressure

The blood pressure monitor is designed for blood pressure measurements during physical activity. Thanks to mechanical and electrical filtering, the BP readings remain reliable even during high load exercise tests. For both stress and resting BP reading, the original auscultatory Korotkov / Riva-Rocci method is used.

Thanks to a built-in speaker, original Korotkoff sounds are clearly reproduced. An ECG trigger is not needed for reliable BP readings, although it is available if desired. Measurement time is very short (usually within 30 seconds) thanks to the rapid cuff inflation.

The blood pressure monitor can be used in 2 ways: Fully integrated control by all common ECG or CPET devices or as a stand alone device with automatic interval measurements.

Various Cuff sizes are available. The cuff is completely washable, thanks to the removeable microphone and inflation bag.

Adjustable Cranks

Adjustability of the cranks allows for optimal force application of different limb lengths and helps tailor the ergonomics of the Lode Corival Paediatric to best fit the test subject. The cranks are adjustable in the range of 80 – 180 mm, in steps of 5 mm. This option will be supplied instead of the standard cranks.

SpO2

This option gives the SpO2 on the display of the control unit of ergometers and can only be ordered in combination with the (Programmable) 7″ touchscreen.

Transport Wheel

The transportation wheel that can be mounted under the Lode Corival Paediatric to easily move your ergometer.

Lode Ergometry Manager 10 – Software to suit your needs

The Lode Ergometry Manager (LEM) is a software package used for controlling Lode ergometers and treadmills.

Easily create and edit protocols

The software enables the operator to program protocols, visualise, save, analyse treadmill data and print customised reports in PDF. Commonly used treadmill protocols are pre programmed as standard.

LEM provides a patient database and the possibility to connect to a SQL server or the Hospital Information System (HIS) with HL7 should this be required. LEM 10 is also backwards compatible with previous versions, allowing you import and use your existing database easily.

Åstrand Module – Estimation of VO2 max

The LEM Expansion Module Åstrand Test is a pre programmed test protocol of the well known Åstrand test with specific visualisations, analysis and reports. It is also possible to adapt the pre programmed Åstrand test to your specific requirements.

Architect Module – User specific, decision making – custom protocols

 

With this expansion module you can create completely versatile protocols, including defining your own outputs and formula’s.

The module is defined in such a way that you can create steps in a graphical way. To show the versatility of Architect, several well known protocols are included, which would not be possible to create without the Architect module because certain decisions and loopings are built-in into the protocols.

In the example to the left, at the start of the protocol stage LEM is asked a question based on HR of the test subject. If HR is below 120 bpm, we add 75 watts additional load, if it is between 120bpm – 134 bpm we add 50 watts additional load, if it is greater than 135 bpm we add 25 watts. Then we wait 180 seconds, after which the load is set to 25 watts, for another 120 seconds.

At this point, we ask LEM what the HR of the test subject is, if it is below 150 bpm they stay at 25 watts load until you decide they exit to protocol. For a HR of higher than 150 bpm, they automatically are removed from the loop and move to the next stage – recovery for example.

 

 

Export Module – Export to Excel

With the LEM expansion module Export it is possible to export data of the LEM database to other programs. The data can be exported to MS Excel. Data of one test subject or multiple test subjects can be exported to an Excel sheet for further analysis.
