Claims7
A device for passive humidification of tracheostomized or intubated patients, comprising an outer body which has an opening for connection to the patient and is connected to at least one seat of a filtering element which is connected to the outside, characterized in that it comprises, on said outer body, a coupling for connection to at least one oxygen delivery duct which ends proximate to the outer part of said filtering element.
The device according to the preceding claims, characterized in that said opening is arranged between said wings.
The device according to one or more of the preceding claims, characterized in that said seat is formed at the outer end of said wings.
The device according to one or more of the preceding claims, characterized in that said at least one filtering element is constituted by a ribbon which is wound on a core which internally forms a channel which can be connected to said delivery duct.
The device according to one or more of the preceding claims, characterized in that said coupling is connected to delivery ducts which are arranged mutually opposite.
The device according to one or more of the preceding claims, characterized in that it comprises, on said outer body, a port which can be removably closed by a plug and is arranged so as to be substantially axially aligned with respect to said opening.
