GuideControl | Evolution in Light Guide Cable Testing

Of course there were already Light Guide Cable Testing devices on the market but if you’d ask the people who used them they all would give the same feedback; “The measurements are fluctuating and the result is interpretable”. So this triggered us to come up with something new and better.
We already build the ScopeControl, the world’s first fully automatic endoscope tester so we were excited to take the next challenge to develop the light guide cable tester, called GuideControl!

Problem description

Because there are already some light guide cable testing devices on the market, which some of them actually do a pretty good job, we needed to listen closely to the users in order to build something that stands out from the competition. Fluctuating measurement results in between measuring attempts, the need for more than 1 tester because a lot of testers support only 1 cable adapter size (and there are about 6 different sizes on the market). The third issue was interpretability, by default regulatory organisations advice to mark a cable as defect when the light transmission drops below 70%. But in practice users are able read the percentage that led to own interpretation.

GuideControl (Cable Testing)

GuideControl is our intelligent light guide cable testing device, specifically designed for the Central Sterilization Department. Existing testers need multiple connectors for the different brands and the test result requires certain interpretation from the user in order to determine whether the light guide cable is good or bad for the OR. The design of the GuideControl creates an unambiguous use, where we have just one connector for all different brands and suppliers of light guide cables. The unique LED interface will let the user directly know, whether the light guide cable is approved (green) or failed (red).

GuideControl also provides the ability to store the measured values. By using datamatrix codes or RFID tags, ‘unknown’ light guide cables can be recognized, and the measured values and snap-shots of the cable are stored to its unique identifier in the cloud.
Where existing testers will only measure the light transmission of the cable, we additionally measure the fiber density and the color correctness. This can give insights on how cables are treated at the OR and the CSSD. Discoloration for example, can disclose the fact of repeatedly turning the light source to high, resulting in burned-in fibers or dissolving glue.

The CSSD manager can check the status and quality of all light guide cables that are in use by the hospital, through the hospitals cloud environment. Here you can adjust your threshold values and get valuable insights by analyzing trends, such as degradation or the lifespan of light guide cables. The connection to the cloud also allows you to choose for automatically ‘care-free’ replacement of your faulty light guide cables.
