Abstract: A device for treating wounds with negative pressure is provided that includes an adhesive film that defines a chamber in relation to the wound; a vacuum source can be adjusted to produce negative pressures in the same chamber; a canister for collecting liquids drained from the wound; a reservoir containing medicated liquids to be instilled in the wound; an unit for setting both the negative pressure and the quantity of administered medication; and a pressure sensor to detect the negative pressure present in said chamber. The device further includes a spiral diffuser mounted on said film comprising a high number of protrusions on tube coils, the spiral diffuser being connected both to vacuum source and to a pump; micro-valves for diffusing medicated liquids, one for each protrusion on coiled tube of spiral diffuser; and a pump administering medicated liquids exerting a pressure capable of opening the micro-valves present in protrusions.

Abstract: A dispensing apparatus for dispensing a unit dose of a pharmaceutical substance, in particular for intranasal administration, is described. The apparatus includes a nozzle unit having a safety cap thereon and an actuating device. The safety cap has legs, which can locate within the actuating device. Upon mounting the nozzle unit on the actuating device, the legs on the safety cap push down a ram in the device against the action of a spring, until the head of the ram engages over a shoulder. The ram is released by depression of a button on the device and by relative movement of two parts of the device.

Abstract: A dispensing apparatus for dispensing a unit dose of a pharmaceutical substance, in particular one for intranasal administration, is disclosed. The unit dose is contained in a cylinder which is moved relative to a piston to expel the contents thereof through a passage in the piston and out of a nozzle opening. The dispensing apparatus includes a case with a base part and a cover.

Abstract: The application describes a dispensing apparatus (1) for dispensing a unit dose of a pharmaceutical substance, in particular for intranasal administration. The nozzel unit (3) has a safety cap (48) thereon and the cap has legs (51) which can locate within the actuating device. Upon mounting of the nozzle unit on the actuating device, the legs on the safety cap push down a ram (8) in the device against the action of a spring (10), until the head (23) of the ram engages over a shoulder. The ram is released only by both depression of a button (34) on the device and by relative movement of two parts of the device. That relative movement is blocked by a wing (53) on the safety cap so that actuation cannot occur until after removal of the cap. Force on the button moves the two parts together and depresses the button, so that the ram is released and is forced by the spring to move a cylinder relative to a piston (71), thereby discharging the contents of the cylinder through the nozzle opening.
