Abstract

A valve comprises an elastically deformable body, 2, through which there is provided at least one flow channel, 4. A sealing member, 6, is located in each channel, 4, to inhibit the through-flow of fluid until a force is applied to compress the body, 2, sufficient to cause an increase in the cross- sectional area of the flow channel, 4, in the region of the sealing member, 6, thereby permitting the through-flow of fluid. A dispenser assembly, 8, incorporating the valve, 2,4,6, comprises a housing, 10, having an externally accessible chamber,12, in which the valve, 2,4,6, is contained and an externally mountable fluid container, 14, for containing fluid, 16, to be dispensed. The fluid container, 14, is provided with an egress port, 18, and is co-operably arranged with the housing, 10, to establish, when co-located therewith, a fluid tight connection between the egress port, 18, and the at least one flow channel, 4, of the deformable body, 2. Preferably a mechanical contact is established between the container, 14, and the deformable body, 2, when co-located with the housing, 10, and is movable relative to the housing, 10, so as to apply the force to compress the body, 2.

Valve and Dispenser Assembly for Fluid

Idee: Göran Cewers, S-Elema

A valve comprises an elastically deformable body, 2, through which there is provided at least oneflow channel, 4. A sealing member, 6,  is located in each channel, 4,  to inhibit the through-flow offluid until a force is applied to compress the body, 2, sufficient  to cause an increase in the cross-sectional area of the flow channel, 4,  in the region of the sealing member, 6, thereby permittingthe through-flow of fluid. A dispenser assembly, 8, incorporating the valve, 2,4,6, comprises ahousing, 10, having an externally accessible chamber,12,  in which the valve, 2,4,6, is containedand an externally mountable fluid container, 14,  for containing fluid, 16, to be dispensed. Thefluid container, 14, is provided with an egress port, 18, and is co-operably arranged with thehousing, 10, to establish, when co-located therewith,  a fluid tight connection between the egressport, 18, and the at least one flow channel, 4, of the deformable body, 2. Preferably a mechanicalcontact is established between the container, 14, and the deformable body, 2,  when co-locatedwith the housing, 10, and is movable relative to the housing, 10, so as to apply the force tocompress the body, 2.

In a preferred form of  the dispenser assembly, 8, shown in the figure, the elastically deformablebody,2, is formed of an elastomeric material having therein or thereon biasing elements, 20,arranged to provide a bias force in opposition to the applied force so as to tend to restore thebody, 2, to its original shape. The body, 2,  is contained within a housing, 10, which is open atone end, 22, and which connects to a specifically adapted fluid, for example liquid anaesthetic,container , 14, at an opposite end, 24.  Th...
