PORTABLE AND PROGRAMMABLE INTERACTIVE VISUAL ANALOGUE SCALE DATA-LOGGER DEVICE

摘要

A portable, interactive clinical data-logger device signals to a patient under investigation a succession of recording time periods spaced apart by predetermined time intervals. After a recording time period has been signalled, questions such as 'What intensity of pain are you feeling ?', 'What degree of discomfort are you feeling ?' or 'How severe is a given symptom ?' are displayed. The patient answers each question by means of a pushbutton-controlled bar graph associated to a pain intensity, discomfort degree and/or symptom severeness representative V.A.S. scale. The V.A.S. data are then stored and available for further processing into an outside computer.
