The super hydrophobic surface and the super hydrophilic surface, or the medical instrument which possesses the both parties of that

摘要

To offer the medical instrument with one feature of this invention, as for this instrument below: (A) the super hydrophobic surface territory of one or more, (b) the super hydrophilic surface territory of one or more which possesses the durometer which at least is 40A, or (c) the super hydrophobic surface territory of one or more it possesses the combination of the super hydrophilic surface territory of one or more which possesses the durometer which at least is 40A. By the fact that such surface is formed, for example, resistance to the movement of the contiguity material which includes the fluid and the solid matter which it adjoins is decreased. As example of the medical instrument surface territory where this invention is beneficial, for example, below: The blood vessel catheter and the urine road catheter, haidororaizakateteru and the guide wire, the pullback sheath, the left cardiac ventricle auxiliary circulating device, the endoscope, the tube and the injection needle inside the windpipe and in addition outside many instruments and/or inside (lumen) the surface is included.
