Nebulizer and reservoir

A nebulizer (1) for a fluid (2), comprising:

• a reservoir (3) containing multiple doses of the fluid (2), and
• a fluid pump (8) for withdrawing a dose of the fluid (2) from the reservoir (3) and pressurizing the respective dose for nebulization,
• wherein the reservoir (3) comprises:
• a tank or bag (4) with multiple doses of a fluid (2) to be nebulized, and
• a housing part (7) containing the tank or bag (4),
• wherein the tank or bag (4) extends in a circumferential direction within the housing part (7) and/or is curved around a central axis (R) of the reservoir (3), and/or
• wherein the reservoir (3) comprises a flexible fluid connection (5) and a connector (6) for fluidically connecting the tank or bag (4) to the nebulizer (1).

A nebulizer (1) for a fluid (2), comprising:

• a reservoir (3) containing multiple doses of the fluid (2), wherein the reservoir (3) comprises:
• a tank or bag (4) with multiple doses of a fluid (2) to be nebulized, and
• a housing part (7) containing the tank or bag (4),
• wherein the tank or bag (4) extends in a circumferential direction within the housing part (7) and/or is curved around a central axis (R) of the reservoir (3), and/or
• wherein the reservoir (3) comprises a flexible fluid connection (5) and a connector (6) for fluidically connecting the tank or bag (4) to the nebulizer (1);
• and
• a fluid pump (8) for withdrawing a dose of the fluid (2) from the reservoir (3) and pressurizing the respective dose for nebulization,
• wherein the reservoir (3) or a tank or bag (4) thereof is arranged at least partially around an energy store or drive of the nebulizer (1) for driving the fluid pump (8) and/or at least partially around the fluid pump (8) or its pump or pressure chamber (11).

A nebulizer (1) for a fluid (2), comprising:

• a reservoir (3) containing multiple doses of the fluid (2), wherein the reservoir (3) comprises:
• a collapsible bag (4) with multiple doses of a fluid (2) to be nebulized, and
• a housing part (7) containing the collapsible bag (4),
• wherein the collapsible bag (4) extends in a circumferential direction within the housing part (7) and/or is curved around a central axis (R) of the reservoir (3), and/or
• that the reservoir (3) comprises a flexible fluid connection (5) and a connector (6) for fluidically connecting the collapsible bag (4) to the nebulizer (1);
• and
• a fluid pump (8) for withdrawing a dose of the fluid (2) from the reservoir (3) and pressurizing the respective dose for nebulization,
• characterized in that the fluid pump (8) comprises a reciprocating conveying element (9), wherein the reservoir (3) is held non-reciprocating by the nebulizer (1) and fluidically connected or connectable via a preferably flexible fluid connection (5) with the conveying element (9).
