Definitions
- the present invention relates to pull throughs such as those suitable for cleaning endoscopes.
- Endoscopes require frequent cleaning. It is found that endoscopes (such as those lined with, for example, a polyurethane sleeve) can be sterilised between uses by a cleaning regime that involves the pushing and/or pulling through of a brush or other cleaning head, the effect of which is to smooth the inwardly directed surface and surface deposits of the polyurethane sleeve or its equivalent. Hence this better enables chemical cleaning and sterilisation to ensure. See for example the post 2 March 2000 published content of PCT/AU99/00669 (WO00/10476) of Novapharm Research (Australia) Pty Limited, the full content of which is here included by way of reference.
- a feature of the pull through of aforementioned WO00/10476 is the requirement that the cleaning member at the end of the pull through be 0.1mm narrower than the passageway of the endoscope to be cleaned.
- PCT/NZOO/00198 published as WO01/28406 of Galantai (Plastics) Group Limited discloses a pull through manufacturing process where the pull through is suitable for cleaning endoscopes.
- the pull through is manufactured reliant upon a filament having at least a thermoplastic surface and a moulded thermoplastic mass about the filament defining a pull through profile adapted for the purpose of the pull through.
- the filament is preferably a monofilament sufficiently stiff to enable its threading through a conduit, passageway or the like of an endoscope for which it is adapted or intended for use.
- the moulded thermoplastic mass i.e. the pull through profile or cleaning feature
- a feature of the manufacturing procedure of a pull through of WO01/28406 is the conditioning of the coil or spool fed filament at an elevated temperature whilst under axial tension so as to reduce coil or spool memory in the filament. This better enables a manufacturing procedure whereby substantially straight pull throughs can be accumulated for packaging or other downstream treatment.
- the cleaning profile, mass or head of WO01/28406 involved a materials blend and outstanding 360° fins requiring matching of the pull through to specific endoscope channel sizes.
- US Patent 5964004 of DC Bean describes an endoscopic tube cleaner where the body of the cleaner extends axially in relation to the tube with a plurality of blades integral with the body.
- a feature of that particular arrangement is the provision whereby each blade of an axially spaced set of such blades is such that there is 360° wiping but each blade itself does not provide for 360° wiping. This may enable some adaptability to different endoscope channel sizes.
- US5964004 states that the invention is directed to a system where the user must be absolutely certain that every portion of the inside surface of the endoscopic tube has been wiped by the blades.
- the present invention is directed, in one aspect, to cleaning apparatus such as an endoscopic pull through with adaptability to accommodate different size circular conduits (e.g. endoscopic conduits, channels, passageways or the like ("channels")) such that the one size can effectively accommodate the cleaning requirement of each of a range of endoscopic channel diameters.
- endoscopic conduits e.g. endoscopic conduits, channels, passageways or the like (“channels")
- channels passageways or the like
- the invention in an alternative aspect, is directed to a manufacturing process suitable for pull through production.
- the invention is a pull through suitable for cleaning a channel of, for example, an endoscope, the pull through having a filament about which, at least in part, there is carried at least one mass to fulfil a cleaning role, said mass defining a sheath at least in part on the filament and at least two radial fins integral with and/or carried by the sheath (or extension thereof) and axially spaced with respect to the sheath and filament axis, wherein said fins are each substantially radially directed with respect to said axial axis yet are of a profile and are formed in a material such that each, without the interference of the other, can assume a configuration for a conduit to be cleaned smaller than that notionally just touchable by the undeformed fins.
