Abstract
A pull through such as might be used for an endoscope where a thermaplastics monofilament substantially free of spool or coil memory has molded thereon a desirable thermoplastic mass profile in a material of lower melting point than at least part of the filament, such melting point differential with preferably pre-heating of the filament ensuring an appropriate keying of the profile on the filament.
Claims27
A pull through comprising
- a filament having at least a thermoplastics surface, and
- a molded thermoplastic mass about said filament defining a pull through profile adapted for the purpose of the pull through,
- the filament being a monofilament sufficiently stiff at ambient temperature to enable threading of the filament through a passageway of a member,
- and said molded thermoplastic mass being of a material of a lower melting point than at least part of said filament.
1 more element
A pull through endoscope cleaning apparatus, said apparatus comprising
- an elongate member capable of being inserted in part through a conduit and thereafter to be pulled fully therethrough, said elongate member being at least in part a first plastic material, and
- an injection molded form located at least adjacent to one end of said elongate member, said form being of a second plastic material and providing at least one of a smoothing and a cleaning effect upon being pulled through the conduit,
- the form of said second plastic material being injection molded onto said first plastic material of said elongate member, a melting point of said second plastic material being less than that of said first plastic material.
