Abstract
A protective sheath for an endoscope probe comprises a pair of elongated plastic sheets peripherally sealed together at the sides and distal ends thereof, while being unsealed at the proximal ends. A first of the sheets is transparent, having greater optical clarity than the other sheet. The other sheet has better frictional slip characteristics than the first sheath. Also, an intermediate plastic sheet may be provided between the pair of plastic sheets, so that the endoscope probe slides into the sheath between the other sheet and the intermediate sheet. The intermediate plastic sheet may have better frictional slip characteristics than the first sheet, to render easier the advancement of the probe into the sheath. The intermediate sheet terminates short of the distal ends of the sheet pair.
Claims19
A protective sheath for an endoscope probe which comprises a pair of elongated plastic sheets peripherally sealed together at the sides and distal ends thereof and unsealed at the proximal ends thereof, a first of said sheets being transparent and having greater optical clarity adjacent its distal end than the other sheet, the other sheet having better frictional slip characteristics than the first sheet adjacent said first sheet distal end.
A protective sheath for an endoscope probe which comprises a pair of elongated plastic sheets peripherally sealed together all the sides and distal ends thereof, and unsealed at the proximal ends thereof, a first of said sheets being made of polyethylene and being transparent with greater optical clarity adjacent its distal end than the other sheet, the other sheet being made of a material selected from the group consisting of EMA plastic and polyethylene, said other sheet having greater frictional slip characteristics and lower optical clarity than said first sheet adjacent said first sheet distal end, said sheath being packaged in an openable outer sheath.
A protective sheath for an endoscope probe which comprises a pair of elongated plastic sheets peripherally sealed together at the sides and distal ends thereof, and unsealed at the proximal ends thereof, a first of said sheets being transparent and having a greater optical clarity than the other sheet, the other sheet having better frictional slip characteristics than the first sheet, said sheath also comprising an intermediate plastic sheet positioned between said pair of plastic sheets and sealed to at least one of said pair of sheets adjacent their respective lateral edges, said intermediate sheet being spaced from said distal sheet ends, whereby an endoscope probe can be inserted from the proximal sheath end between said other sheet and the intermediate sheet, and advanced until a distal tip portion of said endoscope probe engages a distal end portion of said first sheet while spaced from said intermediate sheet, said intermediate sheet having better frictional slip characteristics than said first sheet, said first sheet extending proximally beyond the proximal end of said other sheet, and in which said first sheet and intermediate sheet are transversely sealed together adjacent proximal ends thereof, to prevent an endoscope probe from entering the sheath between said first sheet and said intermediate sheet.
