Remote Control Systems' Radiotelemetry Receiver 7060: its use in clinical colonic motility measurement

Abstract

A new radiotelemetry receiver type 7060 for use with radiopills is described. Its performance under laboratory conditions was assessed and its use for clinical colonic pressure measurements evaluated. The receiver, which resembles a small microcomputer, was easy to set up and worked reasonably well under ward conditions. Difficulties were experienced with the belt aerial supplied with the receiver, which did not reliably pick up signals from a freely moving radiopill. The receiver is not suitable for ambulatory applications. Its main clinical use is in situations where frequent sampling of the radiopill's signal over a long period of time is essential (e.g. colonic pressures). The large quantity of data generated can be fed from the receiver's analogue or digital output on line to a recorder.
