CLEMENT CLARKE ONE WAY VALVE EXPIRATORY MOUTH PIECE is designed to provide protection against possible cross infection amongst patients in expiratory procedures with an existing valve in place that only allows air to flow in one direction. It is used together with the CLEMENT CLARKE MINI-WRIGHT PEAK FLOW METER STANDARD and LOW RANGE. The varnished and non-absorbent finish of the mouth piece allows greater patient comfort by minimising “stuck-lips”. There is excellent seal with the peak flow meters and consistent readings are achieved.
