MEDICAL DRAIN TUBE
Document Type and Number:
Japanese Patent JP3206877
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a patient from having pain by providing inner and outer surfaces at a step part directed to a removal direction with a gentle inclination angle to a drain center axis, and a surface directed toward a tip with a side hole for connecting an inner cavity to an outer surface which is almost parallel to the center axis for smoothly removing invaded tissue from the side hole.
SOLUTION: An internal storage part 1 is provided with an inner cavity 3 by rolling a sheet like a tube, and a groove is provided. The groove is directed to be almost parallel to a center axis, and an outer surface and the inner cavity 3 are connected to each other to form a side hole 4. The side hole 4 is directed toward a tip 5. The internal storage part 1 of a drain tube can be sucked from the tip and the side hole 4 in a side surface of the internal storage part 1. A cross-sectional surface of an outer wall of the internal storage part 1 is provided with a step, and an inner and an outer surface of a step part directed to a removal direction is provided with a gentle inclination angle to a drain center axis. Invaded tissue can thus be smoothly removed, and breakage of the drain tube can be prevented, thereby the drain tube can be removed without giving burden on a patient.
