| 摘要 |
A device (10) and method for substantially preventing contamination of the patient environment by contact thereof with contaminating material associated with the outer surface of an indwelling catheter (70) when extracting same from the patient body, comprising: a collecting duct (20) comprising a distal inlet end (24), having a rigid edge (11), and a proximal outlet (27); an extensible protecting sleeve (86), having a distal open end (83) sealingly attached onto said collecting duct (20) in open communication with said proximal outlet (27) and a proximal open end (87) sealingly attached onto said catheter (70) at or near to the proximal end of the same, said sleeve (86) extending to cover the external surface of said catheter (70) as the same is passed through said proximal outlet (27) of said collecting duct (20); and catheter guiding means (30) mounted by suitable mounting means (31) within said collecting duct (20) at or near said distal inlet end (24) for guiding said catheter (70) towards said proximal outlet (27) of said collecting duct (20) as said catheter (70) is passed through said collecting duct (20), said catheter guiding means (30) being in a spaced relationship with respect to said rigid edge (11) to define a clearance (77) between said catheter (70) or at least a portion thereof adjacent to said distal edge (11) for substantially preventing contact between said contaminating material and said edge (11), and said mounting means (31) minimising runoff of contaminating material that may become attached to said guiding means (30) towards said rigid edge (11). |
