- Another object is to provide such a device which more effectively prepares the inhalable fluid for administration.
- a further object is to provide such a device which can be utilized in many different manners.
- a self-containing device which comprises a container for a liquid, and'inlet means for a gaseous fluid and outlet means for treated fluid at the upper end of the container, the inlet and outlet means being formed of plastic material and having an end formation for sealing the inlet and outlet means and being constructed and arranged to be removed or cut away to open the inlet and outlet means.
- the container may be equipped with.
- an aspirator near the inlet means including anozzle in fluid flow communication with the inlet means for directing the gaseous fluid downwardly and a second nozzle positioned crosswise and adjacent the first nozzle for the eduction of a spray of the liquid, and a bafile member adjacently below the nozzles onto which the spray of liquid is directed and in conjunction with the container wall and liquid surface to nebulize the same.
- a porous gas diffusing element in fluid flow communication may be placed in the liquid, which is confined by the container and which causes the gas to be humidified.

- a tube such as a cannula or catheter (not shown) is telescoped over the tube 32 and the other end inserted into a persons nostril.
- An inhalable gas is delivered by the tube 19 through the bore 23 of the inlet fitting 17 and aspiration and nebulization take place as already described.
- the nebulizedliquid is discharged through the tubular portion 32 which has been opened at the outlet formation 37.
- blister formation 40 (see FIGS. 1 and 2) on an annular protuberance 42 of the outlet section column 30 and this blister formation 40 is provided as a cutable surface to enable the scissors 41 to be readily inserted therethrough, so as to cut away the entire upper portion of protuberance 42 including tubular section 31 and tubular portion 32, after which the opened section of protuberance 42 is connected for face mask or hood application.
- the contents of the container are administered to a single patient and the entire device is discarded when treatment of the patient is completed or when the entire contents of the container have been discharged.
