Putting Tubes to the Test with Terahertz

Kelly Hall Blog 1 Comment

To ensure a long and happy life, we try to be  fairly careful about what we put inside our bodies. From eating our fruits and veggies, to getting our 8+ glasses of water a day and trying to kick that chocolate/chip/deep-fried food habit (hey, we aren’t perfect!), we know that what we put inside our bodies has a direct correlation to the type of lifestyle we lead.

But what happens when things go awry and our bodies need more than what our refrigerators and faucets can provide?

A nearly $4 billion market, use of plastic tubing in the medical industry has been growing since its first appearance in the 1940s. A go-to medical material, plastic tubing not only plays an essential role in transferring fluids, medication, and oxygen but is also a key part of more advanced procedures taking on the roles of catheters, conduits and stents.

Flexible, tolerant of bodily fluids and low in cost, use of plastic medical tubing is only increasing with the growth of minimally invasive surgeries and the continuous development of co-extrusion technologies. (Plastemart: “Steady growth expected for plastic medical tubing”)

With plastic medical tubing playing such an essential role in today’s healthcare practices, it is no surprise that it must undergo stringent testing procedures at manufacturing.

When it comes to ensuring quality, measuring the dimensional tolerances of the various medical tubes is the most critical; effectively measuring the inner diameter (ID), outer diameter (OD), overall wall thickness, concentricity and ovality of plastic medical tubes provides the essential data for quality assurance before these products ultimately make their way to future patients.

Current quality control practices however, are highly invasive, time-consuming and prone to human error. Spending several hours per day conducting these highly-detailed measurements by hand, current practices involve a high level of human interaction and rely on the tube to be cut cleanly to ensure the most accurate data possible. What’s more, human interpretation of the resulting data leaves room for further errors to occur.

In a large and extremely important market, an alternative solution that is accurate, repeatable and time-saving is needed; and a terahertz-powered solution could be the answer.

TeTechS’ MediMeasure™ is a medical tubing dimensional profiling system that uses the unique characteristics of terahertz waves to measure the ID, OD, wall thickness, concentricity and ovality of multi-layer and multi-lumen plastic medical tubes. Powered by TeraGauge™, MediMeasure™ is able to conduct measurements in less than 1 minute on opaque, translucent and transparent plastic tubes and can effectively replace current quality control practices.

Although we can’t always control what happens with our bodies, innovative technology such as TeraGauge™ and MediMeasure™ can help ensure that if things go awry, the essential tools used are in their best form and of the best quality.
