Product details

Efficient polygraph system for sleep apnoea - The SleepDoc Porti 9

The SleepDoc Porti 9 polygraphy device is used for the differentiated diagnosis of sleep apnoea syndrome. Measurements are taken using a thorax and an abdomen sensor.

The device is characterised by three attributes: SMART, Simple and Small

The advantages at a glance:

SMART - Thanks to its integrated Bluetooth interface, the Porti 9 enables wireless data exchange with the prisma SMART max sleep therapy device from Löwenstein Medical. Important signals such as flow, pressure, leakage and tidal volume are transmitted directly to the Porti 9, making therapy settings and therapy monitoring very easy.
Simple thanks to the intuitive plug-in and connection options for sensors and the colour display
Small thanks to its small dimensions and low weight. This makes it very comfortable for patients to wear at night.
Time-synchronised display on the computer with the evaluated polygraphic parameters (respiration, SpO2, pulse and position)
OR5 software available in 11 languages and no software licencing required
Maintenance and service free
