Lode MR Ergometer – Exercise instead of Medicine
The Lode MR ergometer has been specially designed for use within an MRI scanner. The Lode MR ergometers are designed to produce physical stress within an MRI device. The MR ergometer can be used for cardiac examinations, cardiac research, spectroscopy and other examinations and research.
The MR ergometer package contains the MR Ergometer mounted on a frame, specific for the table used with the MRI scanner. Furthermore the package contains the Power Unit, the Carrier, fibre optic communication cables and Lode Ergometry Manager (LEM) 10 software.
4 Models available:
- Pedal
- Push / Pull
- Up / Down
- Ankle Dorsal Flexion
Compatible with various MRI scanners
Our bespoke made frame can be adapted to fit on all major MRI scanner brands, such as; Phillips, GE and Siemans.
When we receive an enquiry we need to capture as much information as possible about your location and setting. This helps us to determine the correct ergometer for your requirements and to make sure we have the necessary documentation of your scanner. Integral to the functionality of the ergometer is the bespoke frame that secures the ergometer to the scanner bed.
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.
Perfect for Stress Testing inside the Magnet
The Lode MR ergometers workload is adjustable in 1 watt increments. The working range of the ergometer depends on the pattern of movement desired. The Pedal has a range of 10 to 300 Watts and the other models (Up/ Down, Push/Pull, Ankle flexion) have a range of 5 to 100 Watts.
This offers a wide working range for test subjects of all strengths and abilities. Each Lode MR Ergometer is standard supplied with the Lode Ergometer Manager 10 Software. Lode Ergometry Manager 10 enables the operator to program protocols, control ergometers, visualise, save and analyse ergometry data and print customised reports in PDF. Commonly used bicycle protocols are pre programmed as standard.
The program also provides a patient database and the possibility to connect to a SQL server or the Hospital Information System (HIS) with HL7. LEM 10 is also backwards compatible with previous versions, allowing you import and use your existing database easily.
Accuracy
For Pedal Ergometer:
Workload below 100w – Accurate within 3W
Workload between 100w – 300w – Accurate within 3%
For Up/Down, Push/Pull and Ankle Flexion Ergometers:
Workload below 100w – Accurate within 3W
Adjustable handgrips
When the MR Ergometer (Pedal) is fixated and the participant is positioned on the MRI table the last step before the test can start is to adjust the position of the handgrips, so that the participant can grab them during the test.
Carrying Frame for easy mounting and storage of the MR Ergometer
The ergometer is stored and transported to the side of the MRI scanner bed on the tiltable trolley frame. The trolley bottom is filled with sand in order to stabilise the frame as the ergometer is tilted onto the bed.
The MR Ergometer trolley has handles to adjust the height and tilt angle. All handles are easy to use and require minimal effort to move the ergometer to the desired position on or off the table.
Easy to Clean
All surfaces on the Lode MR Ergometer are easily wipeable . 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.
Versatile data and ergometer management with – LEM 10
The Lode Ergometry Manager (LEM) is a software package used for controlling Lode ergometers and comes supplied as standard with all Lode MR compatible ergometers. Connection to the Lode MR Ergometer is made via an optical interface cable supplied as standard.
Easily create and edit protocols
The software enables the operator to program protocols, control ergometers, visualise, save and analyse ergometry data and print customised reports in PDF. Commonly used bicycle protocols are pre programmed as standard.
The program also provides a patient database and the possibility to connect to a SQL server or the Hospital Information System (HIS) with HL7. LEM 10 is also backwards compatible with previous versions, allowing you import and use your existing database easily.
Pre programmed Bicycle Protocols:
- 25 Watt / minute Bicycle protocol
- Body Weight Controlled Bicycle protocol
- Isokinetic Bicycle protocol
- Target Distance Bicycle protocol
- Target Energy Bicycle protocol
- Weight Dependent Bicycle protocol
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.
Adjustable cranks for perfect positioning
Get your patient in the optimum position with adjustable cranks. 50 to 90 mm adjustable cranks for MR ergometer to allow for optimal versatility. Suitable for most core diameters and patient sizes.
Service & Warranty
All Lode products are manufactured with precision to ensure reliability in all applications.
Lode ergometers are almost maintenance free, and will give you many years of service when correctly maintained. It is recommended by Lode that the Lode MR Ergometer should be calibrated and serviced once per year. Our team of experienced engineers, use our dedicated Lode calibrator to check the ergometers power output at a variety of power increments and cadences. Giving you peace of mind that the ergometer is fully functional and as accurate as the day it left the factory.
The Lode MR Ergometer has a 12 months parts and labour warranty. Extended warranty is available for an additional 4 years (5 in total).
Cranlea offer a comprehensive annual maintenance service, checking the running and electrical parts of the ergometer. Contact our service team here.
