Morgan Technical Ceramics has introduced a new tube contact sensor to precisely distinguish the obstructions in medical infusion lines. The sensor detects the pressure changes non-invasively in a flexible tube and eliminates the need for disposable cassettes.
The sensor is ideal for using in soft thin-walled tubing. It gives exceptional performance and is able to sense both positive and negative pressure changes from -0.5 to 1 bar.
The MEMS silicone machined technology and an accurate machined lid and catch are integrated in the pressure sensor. The sensor is ideal for medical grade silicone rubber tubing having 4 to 4.7 mm external diameter and 0.8 mm wall thickness. The housing geometry of the sensor is planned in a way to reduce footprint. It is available with a short flexi-circuit to facilitate simple connection through a typical ZIV connector.
The sensor can be modified to fit particular OEM needs such as housing geometry, materials, tube diameter, and connector type. It can be fitted in any direction. If a clamping mechanism option is preferred, then it can be provided without lid and catch. The company’s ElectroCeramics facility has created the sensor.
The main safety factor for medical equipment is exact pressure detection. When there is a block in the line, the sensor can sense the pressure change that specifies the blockage.
