Abstract: A fluid dispenser device including a body (10) with a dispenser orifice (1), a plurality of reservoirs (21) on a strip (20) that includes a leading end (25) and a trailing end (28), a reservoir-opening mechanism (30) adapted to open a respective reservoir upon actuation, and a drive mechanism (40) for the strip (20) and bring a reservoir into register with the opening mechanism. A movable wall (500; 600, 601) separates a storage housing (11) for the elongate strip (20) from a reception housing (15), the elongate strip (20) disposed mainly in the storage housing (11) before the device is used and displaced progressively in the reception housing (15) during use. The movable wall (500) causes the volume of the storage housing (11) to decrease progressively, and the volume of the reception housing (15) to increase progressively.

Abstract: Apparatus, e.g. a syringe, for dispensing foam includes means for ensuring that only foam of adequate quality is dispensed. In use, the syringe may be filled from a pressurised canister which generates foam e.g. for therapeutic use in treating varicose veins. An initial quantity of foam dispensed from the canister may be of inadequate quality in which case it should not be used: the syringe includes means to ensure that this initial quantity of foam is diverted to a waste port or to an internal waste chamber e.g. located in the syringe plunger. Foam dispensed after the initial quantity of poor quality foam is stored in the main barrel of the syringe ready for administration to a patient in need of treatment.

Abstract: A foam transfer device (600) is described, for use with aerosol canister apparatus for producing a sclerosant foam for the treatment of, inter alia, varicose veins. The device enables diversion of an initial quantity of below-specification foam from the canister to waste, e.g. to an integral waste chamber, before dispensing a further quantity of foam for use in treatment. The switching of the flow from the waste chamber to a different outlet (618) for use is accomplished without interrupting the flow from the aerosol canister since this would cause the foam to drop below specification again. The waste chamber may be transparent so that the foam entering it can be observed and a decision made by a user when to stop diverting foam to waste. Alternatively, the foam may be diverted automatically e.g. when a set time has elapsed or a set volume of foam dispensed. The foam for use is normally dispensed into a syringe for subsequent injection into a varicose vein of a patient.

Abstract: A blister pack dispensing device comprises a housing having first (10) and second (12) walls and containing a blister pack (23) and a movable frame (14). The first wall (10) has an array of apertures (11) which correspond to the array of blisters on the blister pack (23). The second wall (12) has an array of buttons (13) which are aligned with the apertures (11). Each button (13) is provided with a projection (22) while the frame (14) has corresponding apertures (15). The frame may be urged by a user to a first position in which the projections (22) on the buttons (13) are aligned with the apertures (15) to allow the buttons (13) to be depressed to disperse the blister contents through the apertures (11). A spring (17) restores the frame (14) to a second position, when released by the user, such that the projection (22) are misaligned with the apertures (15) on the frame (14) and prevent the buttons (13) being depressed.
