Abstract:
An inhaler has a housing containing a chamber (1a) providing a reservoir (8) for liquid providing an active ingredient to be supplied to a liquid outlet (10a). First and second electrodes are spaced apart (11 and 12) with the first electrode being provided at or adjacent the liquid outlet (10a). A voltage supply (5, 7) is activated in response to air flowing through an air inlet (30) of the housing to provide a potential difference between the first and second electrodes (11 and 12) to create an electric field for causing comminution of liquid issuing from the liquid supply outlet (10a) to produce a stream of electrically charged comminuted matter for supply to the nasal passages of a user via an outlet (4) of the housing.
Abstract:
A device for comminuting a liquid, which comprises at least two electrohydrodynamic comminution means (24) arranged so that in use comminution of opposing polarity are formed which are substantially admixed after formation and a pump (22) for use in the dispensing device.

Abstract:
An eye covering (700) for covering an exposed surface portion of an eye, the covering comprising a body having front and rear surfaces (702a and 701a) with the rear surface being shaped to conform to said exposed surface portion (701, 702) and at least a portion of the body comprising biologically compatible polymer fibre.
Abstract:
A dispensing device and method for forming at least partially solid or gel-like material from a liquid are described. In one example, at least one liquid issuing from an outlet is subjected to an electric field causing the liquid to form at least one electrically charged jet which, after formation, forms a fibre (F) or breaks up into fibre fragments (FF) or particles (D). The thus formed at least partially solid or gel-like material may be directly deposited, by virtue of the energy in the electrical field, onto a surface area, for example an area of skin enabling, for example, formation of a dressing for a wound or burn which is of high specific area and extremely absorbent. A biologically active ingredient such as for example a pharmaceutical ingredient or biological matter such as DNA may be incorporated into the fibres (F), fragments (FF) or particles (D). In another example, fibrils, particles or microcapsules incorporating a biologically active ingredient may be supplied for oral or nasal administration to an animal such as a human being.
Abstract:
A device for comminuting a liquid, which comprises at least two electrohydrodynamic comminution means (24) arranged so that in use comminutions of opposing polarity are formed which are substantially admixed after formation, so as to provide a comminution having a residual electrical charge.
Abstract:
Consumable or dissolvable tablets are manufactured by: supplying a liquid containing a biodissolvable carrier to an outlet (41); establishing an electric field between the outlet (41) and a support surface (6) to cause liquid issuing from the outlet to form at least one fibre or fibrils of the biodissolvable carrier which fibre or fibrils deposit(s) onto the surface to form a fibre web or mat; separating the web or mat into a plurality of individual tablets; and incorporating at least on e active ingredient on or in the tablets.
