Specification
Bard Limited, a UK unit of C R Bard Inc., is involved in the servicing of Bard® Magnum® biopsy needle injector guns for its clients located across the globe. In the reusable handheld instrument, the key component is a powerful spring equipped with a dual-action trigger for handling the biopsy sample.
Since the compressed spring is locked in place by the cocking slide, the resistance applied by single-finger pressure should be within design specification. The resistance should be neither too strong for the operator’s finger, nor too weak to carry out a complete, effective insertion and removal.
Tolerances have been defined by Bard for the force needed to cock the gun and for continued compliance, Bard was seeking an instrument to measure every unit.
The solution
To meet this requirement, two MultiTest 1-i test stands were supplied by Mecmesin, with a bespoke grip system for holding the sample. The gun to be tested is securely clamped into position, while the cocking slide is engaged by an upper stirrup.
Custom test sample grips
The Emperor™ software is programmed to perform a series of tests, showing instant green/red pass/fail indicators and real-time characteristic graphs. Every unit is referenced, and all test results are saved for subsequent analysis and reporting. The new instrument enables a consistent testing, rapid throughput, and accurate reporting. As a result, Bard is able to save considerable time and money.

Testimonial
The performance to standard of our biopsy devices is critical, and our MultiTest systems enable a rapid and accurate assessment of every one. The repeatability of the test cycle, and above all the traceability of each unit under test, give us the guarantees we need.”
