Interface Data Systems Develops Sensor for Measuring Blood Clotting

3/22/2004 - Interface Data Systems (IDS), a wholly owned subsidiary of White Electronic Designs Corporation (NASDAQ:WEDC) expands their capabilities by working in conjunction with Hemosense, a medical device manufacturer, to develop a test strip for their INRatioTM meter.

“The INRatioTM meter is a diagnostic Point Of Care system that provides Prothrombin Time (PT) and International Normalized Ratio (INR) results using fresh capillary whole blood.” PT handheld testing devices are the most common way to measure blood clotting levels. Using the INRatioTM device, PT test results are reported in INR, a standardized conversion unit.

IDS utilized its conductive printing technology to help design and manufacture a sensor intended to assist in the testing of coagulant in a patient’s blood, while ensuring complete functionality of the testing device. This sensor is a disposable test strip that is inserted into the PT device and enables users to monitor blood clotting time more effectively while automatically performing electronic self-tests.

Experience in the sensor technology field made IDS a sensible choice and partner for Hemosense. As a result, for the past 5 years IDS has worked closely with Hemosense to produce the test strips for their INRatioTM Meter. Interface Data Systems manufacturers a complete line of keypads, sensors, graphic overlays, labels, and other printed products using conductive, thermochromic and other specialty and standard inks.
