Definitions

  • Figure 13 of WO 03/011379 shows a particle cassette having a first cassette part 70 with a membrane 71 heat-bonded thereto and a second cassette part 72 with a membrane 73 heat-bonded thereto.
  • the first and second cassette parts are brought together in the longitudinal direction such that ribs on the external surface of the second cassette part interact with the inside annular surface 78 of a protrusion on a first cassette part. This provides an interference fit which holds the first and second cassette parts together.
  • the particle cassette is designed to be assembled by hand. A problem with such hand assembly is that the chamber 77 for the confinement of particles is not hermetically sealed.
  • the present invention addresses the above-mentioned problem by providing a method of producing a particle cassette, apparatus for producing a particle cassette, a kit of parts which, when assembled, forms a particles cassette, a particle cassette and first and second cassette parts which allow a properly hermetically sealed particle confinement chamber to be created.
  • platens allows the predetermined force to be transmitted reliably to the first and second cassette parts such that the sealing mechanism can reliably be achieved at the point of contact between the cassette parts.
  • Figure 9 shows apparatus for producing a particle cassette according to the present invention in the initial position
  • the reservoir 100 may comprise a valve rather than a frangible tip and may be positioned such that gas flows directly out and towards the filter rather than having to turn 180° upon exiting the reservoir.
  • a silencing system and a spacer for spacing the nozzle exit from the target may be provided as is known in the art.
  • the particle cassette of the present invention is generally applicable to any type of needleless syringe in which particles are picked up and entrained in a gas flow.
  • the radially outermost face 260 is the outer face of a series of castellations surrounding the perimeter of the second cassette part 250. As shown in Figure 2, these castellations have a tapered entry section which assists in the alignment of the first and second cassette parts. The reason for using castellations is to allow air to escape from between the cassette parts as they are brought together.
  • the one or more ribs 266 may be located either on the outer surface of the second cassette part (as shown in Figures 2 and 3) or on the inner surface of the first annular protrusion 214 such that an interference fit or friction fit is directly provided between the first and second cassette parts.
  • the ribs are preferably located on the outer surface 260 of the second cassette part but can just as easily be provided on the inner surface of the first annular protrusion 214 of the first cassette part 210.
  • the membrane 204 comes into contact with the inner part of the sealing face only, as shown in Figure 4b. At this point, there will be a very small area over which the membrane 204 is in contact with the sealing face 220. At this point the first and second cassette parts are preferably quite strongly held together by the interference-type interaction between face 260 and first protrusion 214 (e.g. via ribs).
  • the pressure in the first column is the pressure applied to a 50 mm diameter piston in the apparatus of Figure 9.
  • the actual load in Newtons is calculated and shown in the second column.
  • the dwell time for which the load is applied is given in the third column and the number of cassettes studied for each set of operating parameters is given in the fourth column.
  • the fifth column gives the number of cassettes that did not pass the seal integrity test.
  • the sixth column gives the total height of the assembled particle cassette after assembly. This is a measure of the size of the seal that has been achieved - due to the taper, a smaller total height means a larger seal area.
