Patent number: 10272213Abstract: Fluid delivery device for discharging a fluid, having: a housing; piston pump; biasing mechanism; and trigger mechanism. The housing has a basal end and a discharge end with outlet for discharging the fluid. The piston pump has a casing defining a pump chamber for storage of fluid, a piston slidably movable relative to the pump chamber, a piston plunger, and a delivery channel. The trigger mechanism is movable from a cocked configuration wherein the trigger mechanism prevents transfer of a biasing force of the biasing mechanism to the casing to a triggered configuration with the trigger mechanism enabling transfer of the biasing force to the casing to cause movement of the casing towards the housing outlet to discharge fluid from the pump chamber, along the delivery channel and out of the outlet of the housing. The biasing mechanism has one or more flexible catch members and a manually operable trigger.Type: GrantFiled: July 14, 2014Date of Patent: April 30, 2019Assignee: CONSORT MEDICAL PLCInventor: Paul Allsop

Publication number: 20110116094Abstract: Surface plasmon generation on a metal or semiconductor layer at an outer surface of an optical waveguide, using light reflected or scattered from inside the optical waveguide. One aspect provides a main optical waveguide (11) (e.g. optical fibre) having a second optical waveguide (18) adhered thereto, the second optical waveguide including an optically transparent material (610) separating two surface plasmon supporting layers (600, 620). Another aspect provides a surface plasmon supporting layer of material(s) adhered to the main optical waveguide, the layer having photo-induced regions of material compaction. The regions of compaction may cause un-inscribed refractive index modulations in the main optical waveguide. The surface plasmons are coupled to the guided mode(s) in the main optical waveguide. Surface plasmon resonance depends on sample material in contact with an outermost surface plasmon supporting layer.Type: ApplicationFiled: November 4, 2008Publication date: May 19, 2011Applicant: ASTON UNIVERSITYInventors: Thomas David Paul Allsop, Ian Bennion, David John Webb, Ronald Neal

Publication number: 20090303489Abstract: The generation of surface plasmons on a metal layer arranged upon an outer surface of an optical waveguide, using light reflected from inside the optical waveguide. The reflected light may be a reflected part of guided light travelling along the optical waveguide and may be a back-reflected (e.g. obliquely back-reflected) part of the guided light. The reflected part of guided light may form a radiative optical mode(s) which is used to excite surface plasmons and which is also coupled to the remaining guided mode(s) of the light from which it derives. This coupling of the radiation mode(s) and the guided mode(s) enables changes in the radiation mode(s) to cause consequential changes in the guided mode(s) of light. Such changes in the radiation mode(s) may occur due to the coupling of the reflected mode(s) to the surface plasmons they excite at the metal layer.Type: ApplicationFiled: July 13, 2007Publication date: December 10, 2009Applicant: ASTON UNIVERSITYInventors: Thomas David Paul Allsop, David John Webb, Ronald Neal, Ian Bennion
