Title:
FLEXIBLE PIPE
Document Type and Number:
Japanese Patent JP3262858
Kind Code:
B2
Abstract:
PURPOSE: To simplify the sealing structure of a pressurizing pipe and to improve the workability for sealing by providing the outer periphery of the flexible pipe with the pressurizing pipe in the state of disposing a pressure expandable pipe part in a curved part.
CONSTITUTION: Pressurizing air flows from a compressor 16 into the second pipe part 6b of the pressurizing pipe 6 when a solenoid valve 25 connecting to the pressurizing pipe 6 existing in the direction desired to be curved by the operation signal from an operating part 20. The pressurizing air flows into the pressurizing chamber 8 of the first pipe part 6a of the pressurizing pipe 6 to pressurize and expand the pressurizing chamber 8. The outer peripheral side of the pressurizing chamber 8 expands and the outer periphery of the curved part 10 is correspondingly pulled. The curved part 10 is thereby curved in the direction opposite from the expanded pressurizing chamber 8. A catheter 1 is disposed with a pressurizing pipeline 6 having the pressurizing chamber 8 formed by the pressure expandable first pipe part 6a on the outer periphery of the catheter body 2, by which the sealing structures of the pressurizing pipe 6 and more particularly the pressurizing chamber 8 are simplified, the workability for sealing is improved and the sealability is improved.
