Metran believes that the most important requirement of equipment in the clinical field is to offer reliability and safety to both clinicians - the providers, and patients - the receivers of treatment. Our own R&D forms the fundation for the high quality of our products. We have been making a large upfront investment in our R&D in order to meet the sophisticated needs of physicians at the front lines of clinical fields, to attentively respond to their requests, and to provide high-quality products in a timely manner.

Components Developed by Metran
Piston

For Calliopeα. A magnet-joint-type transverse piston that greatly reduces noise compared to conventional pistons.

Rotary Valve

The heart of the R100. Because of this switching valve, which converts linear airflow into oscillatory airflow, high-capacity HFO can be used for adults.

Linear motor and piston

For the Humming V. A linear motor the driving force, and a piston for high frequency oscillation (HFO)

Diaphragm

This converts the oscillatory airflow from the rotary valve into a smooth sinusoidal pressure waveform that becomes the basis for HFO

 Breathing Circuit for Hummax (heated humidification system)

This uses a porous hollow fiber polyethylene membrane. It eliminates the problem of insufficient moisture content in inhaled gas by providing humidified gas at a uniform relative humidity of 100% in proportion to the temperature in the breathing circuit.
