DEVICE FOR DETECTING A DANGEROUS RESISTANCE TO FLOW IN A FLOW OF GAS THROUGH A FILTER EQUIPPED, IN CASE, WITH AN HME
First Claim
1. A device, housed in a filtering apparatus, for detecting and showing an excessive resistance to flow in a gaseous fluid through a filter;
- said filter dividing said filtering apparatus into a patient room and a ventilator room; and
wherein said device is designed to detect and to show the difference in pressure existing between said ventilator room and said patient room.

Abstract
A device (10) for detecting and showing a dangerous resistance to flow in a gaseous fluid through a filter (102). The device (10) is characterized:
by the fact that it comprises a body (11);
by the fact that the body (11) is divided into two chambers (CH1, CH2) by an elastic membrane (MBN); a preferably calibrated hole (13) connects the first chamber (CH1) with the patient end (A); the second chamber (CH2) being in communication, instead, with the ventilator end (B), by means of a pressure-relief channel (14), which traverses the filter (102); and
by the fact that it is provided with elements for detecting and showing a dangerous resistance to flow in a flow (FL) of gas that traverses the filter (102); the detection elements comprising the membrane (MBN).
