초록 ▼

A device for passive humidification of tracheostomized or intubated patients, comprising an outer body which forms 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, the device further comprising, on the outer body, a coupling for connection to at least one oxygen delivery duct which ends proximate to the outer part of the filtering element.

대표청구항 ▼

1. A device for passive humidification of tracheostomized or intubated patients, comprising:at least one filtering and humidifying element having an internal channel;an outer body enclosing said at least one filtering and humidifying element, said outer body having a first opening adapted to connect to a patient, at least one second opening adapted to receive said at least one filtering and humidifying element, at least one oxygen delivery duct, and a coupling on said outer body connected to said at least one oxygen delivery duct, said internal channel of said at least one filtering and humidifying element being connected to said at least one oxygen delivery duct to conduct oxygen from said, at least one oxygen delivery duct through said internal channel; andat least one cross-member having a first end pivotally connected to said outer body and a second end removably connected to said outer body for removably retaining said at least one filtering and humidifying element in said outer body, said at least one cross-member being spaced apart from said channel of said at least one filtering and humidifying element and redirecting oxygen from said channel through said at least one second opening of said outer body through said at least one filtering and humidifying element to said first opening, so as to filter and humidify said oxygen supplied to the patient from said oxygen delivery duct.2. The device according to claim 1, wherein said at least one filtering and humidifying element comprises two filtering and humidifying elements, said at least one second opening comprises two second openings, and said outer body comprises two mutually inclined flattened wings including said two second openings for receiving said filtering humidifying elements.3. The device according to claim 2, wherein said first opening is arranged between said wings.4. The device according to claim 1, wherein said at least one filtering and humidifying element comprises a ribbon which is wound on a core which internally forms said internal channel connected to said oxygen delivery duct.5. The device according to claim 1, wherein said at least one delivery duct comprises a plurality of branches, and said coupling is connected to said plurality of branches of said at least one delivery duct, and wherein said plurality of branches are arranged mutually opposite.6. The device according to claim 1, wherein said outer body comprises a port which can be removably closed by a plug, and wherein said port is arranged so as to be substantially axially aligned with respect to said first opening.
