Claims13
A device for detecting the relative humidity in a breathing circuit;
- comprising:
- a housing closed towards the outside by a transparent element and towards the inside by a membrane permeable to the humidified gas passing through an equipment to which said device is applied;
- a humidity indicator element disposed inside the housing, the humidity indicator element dividing the housing into a first chamber and a second chamber, the first chamber being located between the humidity indicator element and the membrane, the second chamber being located between the humidity indicator element and the transparent element.
A heat-moisture exchanger in a respiratory circuit comprising:
- a central container having a filter therein;
- a first connector connecting the central container to a patient;
- a second connector connecting the central container to a ventilator;
- and
- a device housed on a wall of the central container, including:
- a housing having a first wall and a second wall, the first wall including a membrane permeable to the humidified gas passing through the heat-moisture exchanger, the second wall including a transparent element;
- and
- a humidity indicator element disposed in the housing and separating the housing into a first chamber and a second chamber, the first chamber being located between the humidity indicator element and the first wall, the second chamber being located between the humidity indicator element and the second wall.
