A new tube contact sensor is now available for accurate detection of occlusions in medical infusion lines. The sensor reportedly allows non-invasive detection of pressure changes in a flexible tube without the requirement for disposable cassettes; as a result, it can provide medical device OEMs with a simple and reliable method of recognizing when the tube is blocked.
The pressure sensor can be used with soft thin-walled tubing and can be clipped on and removed. It reportedly can detect both negative and positive changes in pressure from -0.5 to 1 bar with a sensor accuracy of ± 0.05 bar. The pressure sensor combines MEMS silicone machined technology with a precision machined lid and catch. It is suitable for a 4-4.7 mm outside diameter x 0.8 mm wall thickness medical grade silicone rubber tubing. The housing geometry has been designed to minimize footprint, and it comes with a short flexi-circuit for easy connection via a standard ZIV connector (6 pin 0.5mm pitch).
