Definition
Noun: 1. A medical instrument used in percussion: A small, thin, flat object, historically often made of ivory or metal, that is placed against a patient's body during a physical examination. The examiner then taps (percusses) the plessimeter with another instrument (a plexor) to produce sounds that help assess the condition of the underlying organs or tissues.
Usage
The word "plessimeter" is a highly specialized medical term. It is used almost exclusively in the context of historical or traditional clinical diagnostic techniques, specifically percussion. * The physician placed the plessimeter on the patient's chest and began the examination. * In the 19th century, a plessimeter and plexor were essential tools for diagnosing chest conditions.
Advanced Usage
- The technique of using a plessimeter is called mediate percussion, as the sound is mediated (transmitted) through the instrument, as opposed to immediate percussion where the examiner taps directly on the body.
- The use of a dedicated plessimeter has largely been replaced in modern medicine by the use of the examiner's own finger as the mediating surface.
