Abstract

Contact between a medical device and tissue accounts for approximately a third of damage to soft tissue in hospitals. The use of sensors at the interface between the device and tissue can be used to maintain the optimum pressure and reduce such injuries. A sensorised endotracheal tube has been developed and is proposed as a method of reducing soft tissue damage and improving design of future devices. Optical fibre sensing is used to monitor both cuff contact pressure (via a fibre Bragg grating) and tissue perfusion (via reflectance photoplethysmography). The monitoring system developed has been used in an animal study and demonstrates reliable measurement of contact pressure and perfusion.
