Lode Brachumera Sport

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.

Lode Brachumera Sport – The dependable Arm Ergometer

The Lode Brachumera Sport has an adjustable workload of 10 to 3000 watts. This offers an enormous working range for test subjects of all strengths and abilities. The communication and network module built into the Lode Brachumera Sport will easily connect with our range of Cortex Metabolic devices or ECG devices and Lode’s own Ergometry Manager Software (LEM).

The ergometer is supplied with a 7″ colour touchscreen.

Superbly Accurate

Workload below 100w – Accurate within 2W

Workload between 100w – 1500w – Accurate within 2%

Workload between 1500w – 3000w – Accurate within 5%

Designed to be sweat-proof

The housing of the ergometer is designed in such way that sweat cannot drip into the mechanical parts and cables are protected. This ensures a long lifetime and makes the ergometer insensitive for malfunction. That being said, all surfaces on the Lode Brachumera Sport 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.

Display options and features

7″ Touchscreen Control Unit (fitted as standard)

The 7″ Colour Touchscreen enhances the capability of the Lode Brachumera Sport 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 Brachumera Sport 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:

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.

Lode Ergometry Manager (LEM) 10 – Software to suit your needs

Versatile data and ergometer management with – LEM 10

A cutting-edge software solution tailored for medical professionals, offering comprehensive control over the Lode Brachumera Sport with in-depth monitoring of ergometric parameters in a variety of clinical and research settings.

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.

Further Expand LEM

LEM 10 can be extended with various modules, each with its specific functions and visualisations. The Lode Ergometry Manager can be used for testing and training in several rehabilitation settings, sports medicine, physiotherapy and research environments.

Wingate Test Module – For explosive power assessment

The Wingate test is a 30 seconds enduring sprint test in which the torque is kept at a constant rate depending on the bodyweight of the test subject. With this option we obtain online information about anaerobic capacity and power. The data is corrected for the moment of inertia to give you the realistic information about the power output (depending on the acceleration of the test person).

In LEM 10 it is possible to compare different software versions (algorithms to correct the moment of inertia) with each other. It is also possible to adapt the pre programmed Wingate test to your specific requirements. Create different, multiple Wingate tests to define the optimum settings and save special Wingate views for testing and analysis.

Besides the rpm dependent and rpm independent modes of the ergometer, the Wingate software gives you a constant torque mode.

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.
