HiCycle Durability Tester

ViVitro offers a family of quality data acquisition software products to aid in collection of data to meet ISO5840 requirements including ViVitest, Hitest and QCtest. The software is pre-installed on a laptop and tested with all hardware and A-D converters prior to shipment.

Each complete system is supplied with the following components to make up a functional system:

• I/O Module – inputs/outputs signals from the software
• Laptop
• Connecting cables
• Software (ViVitest, Hitest or QCtest)
• AmPack Pressure Measuring System including transducers and amplifier

When coupled with the HiCycle or the Real-Time Wear Tester, Hitest provides the most powerful, userfriendly tool for durability testing. Operators are able to monitor pressure and collect data through an intuitive user interface. Hitest provides accurate pressure data and statistical analysis to ensure the tested devices are meeting ISO5840 standards. The results highlight the percent of cycles and percent time per cycle the device is meeting or exceeding target pressure.

The ViVitro HiCycle Cart makes the ViVitro HiCycle system portable and raises it to a comfortable working height. The HiCycle Cart features:

• Locating pin and quick release fasteners
• Locking castor wheels for secure positioning
• Height adjustable pressure head post

Compact, battery-operated stroboscope enables operator to view devices while they are cycling. The rechargeable hand-held system provides mobility throughout the lab. It delivers fast and accurate cycle per minute measurements to verify cycle rates.

• User adjustable flash rates - 40.0 to 12,500 fpm (flashes per minute)
• Advance or retard flash timing by degrees of angle, without changing actual fpm
• Includes AC adapter and extra flash bulb

 

Precision, handheld digital pressure reference manometer conveniently calibrates pressure transducers. Can be recalibrated in the field for zero, span, and linearity.

• Accurate primary standards to calibrate devices locally
• Engineering Units - Inches of H₂O (select 4° C, 20° C, or 60° C), PSI, mm of Hg, inches of Hg, mBars, Bars, kPa, kg/cm², cm of H₂O and user selectable scaling.
• 1 point of 5 point calibration options
• Accuracy: ±0.05% FS
• Media Compatibility - DN: Non-isolated differential sensor for clean, dry, non-corrosive gases. GI & AI: Isolated Gauge or Absolute sensor for fluids compatible with 316L SS

This enhanced version of the ViVitro HiCycle Durability Tester supports mitral valve durability testing for devices up to 55 mm in diameter. The Mitral HiCycle tests up to three devices simultaneously.

The Mitral HiCycle system uses the same electrodynamic motor as the original ViVitro HiCycle to drive three pistons within fluid-filled, temperature-controlled chambers moving the device rather than the fluid. The result is more stable fluid flow. Cycle rates are adjustable from 500 – 1,650 cpm. The Mitral HiCycle is available as a complete system or an upgrade kit can be purchased to convert existing HiCycles. The Mitral HiCycle is fully compatible with all the other ViVitro HiCycle components and accessories including:

• Data Acquisition Software
• HiCycle Cart
• Bellows
• Stroboscope
• Manometer
