Dosating unit for an ultrasonic atomizer device
First Claim
1. A dosating unit removably mountable to an atomizing device, said unit comprising:
- an elongated first section for accepting therein an ampoule containing liquid to be delivered to the atomizing device through a delivery pipe; and
a second section secured to said first section and including a drive mechanism for cooperating with a plunger in the ampoule to cause said plunger to translate within the ampoule to force liquid therein through said liquid delivery pipe, a transmission mechanism for converting rotary motion applied thereto into translating motion applied to said drive mechanism and a driving member for applying rotary motion from a motor in the device to said transmission mechanism.

Abstract
The invention relates to an ultrasonic atomizer device (2) for a fluid (60), in particular a bronchospasmolytic agent, in which a propelling element (10) operable by an electronic circuit (6) to deliver the fluid to an atomization surface (28) that is also supplied with ultrasound waves from the electronic circuit (6) is provided in a housing (4), the propelling element (10) having a coupling member (32) which is meshing with a further coupling member (34) of a replaceable dosating unit (14) for transferring propelling power to the dosating unit (14) to effect a linear movement (68) of a piston (66) arranged in an ampoule (28) within the dosating unit (14). The invention also relates to a system comprising a device (2) as described and a dosating unit (14) inserted into that device (2).

9. A dosating unit removably mountable to an atomizing device, said dosating unit comprising:
-
a housing for accepting therein a cartridge containing a liquid to be delivered to the atomizing device; a fluid delivery pipe having an inlet into which liquid in the cartridge is introduced when said fluid delivery pipe is in an operating position on said housing, and an outlet for delivering fluid to an atomizing surface of the atomizing device; and positioning means on said housing for cooperating with the device to locate said outlet precisely in three orthogonal directions relative to the device, wherein said outlet is precisely located relative to said positioning means so that said outlet will be precisely located in the device when the dosating unit is in the operative position thereof. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A dosating unit removable mounted to an atomizing device, said unit comprising:
-
a housing accepted by the atomizing device; an ampoule containing a medicament liquid to be supplied to the device for atomization, said ampoule being contained in said housing; and a housing cover disposed on said housing and having a fluid delivery pipe for piercing said ampoule, said cover and said housing including cooperating securing means for securing said cover to said housing in a first position wherein said fluid delivery pipe does not pierce said ampoule and a second position wherein said fluid delivery pipe pierces said ampoule, said securing means resisting movement of said cover from said second position toward said first position. - View Dependent Claims (20, 21, 22, 23, 24)
