Abstract: An inhaler for inhalation of a medicament from a pierced capsule has a swirling or emptying chamber where the capsule is emptied by inhalation action of an operator. A rotary magazine for a multi-unit does inhaler which holds a number of capsules containing a medicament in a number of recesses arranged around the periphery of the magazine. The capsules are held in place by pins or plugs at both ends. Either the capsules are pierced before being loaded into the magazine or they are pierced by the pins when they are loaded into the magazine. In either case a seal may be provided around the ends of the capsules near the holes which are plugged to keep them fresh. When a recess is rotated to a particular position within the magazine then it releases its capsule. Contents of a capsule are drawn out during inhalation when the capsule is in the swirling chamber. A motor can be used to operate the magazine.

Abstract: An inhaler for inhaling pulverulent medicament from within a capsule comprises a chamber (24) within which the capsule is free to rotate while having its longitudinal axis in the median plane of the chamber and thus generally parallel to the front and rear walls (30) and (31) of the chamber, by virtue of the fact that the spacing between said front and rear walls is less than the axial length of the capsule but just greater than the diameter of the capsule. The device includes pins (21) serving as opening means to pierce the ends of the capsule while it is seated in a recess (25), whereupon the retraction of the pins (21) allows the capsule to be entrained into swirling airflow in the chamber (24) during inhalation of air through air inlets (26) and out through a mouthpiece nozzle (27).

Abstract: A single handed breast pump comprises a pump body (1) housing a piston (7) releasably connected to a hand lever (9) itself releasably pivoted to the pump body, the latter including a funnel (2) to be laid against the nipple and an outlet (4) at which a container may be connected. The funnel connects with a variable volume chamber in the pump body, said chamber having valves (11, 24) respectively for venting and for opening communication with the container outlet, whereby on operation of the hand lever an alternating pressure can be built up and relieved at the funnel.
