  • Patent number: 9011745
    Abstract: It is an object to stably provide a thin-walled flexible medical tube having excellent kink resistance and tensile strength by a simple manufacturing method. The object is achieved by a method for manufacturing a medical tube that includes a coil layer on an inside of an outer layer tube made of a resin, and the method includes inserting the coil layer into the outer layer tube and heating the outer layer tube at a molding temperature lower than a melting point of the outer layer tube, thereby bringing the outer layer tube into contact with the coil layer to slidably fix the outer layer tube onto the coil layer.
    Type: Grant

  • Publication number: 20110245807
    Abstract: Provided is a medical tube which is flexible and achieves good kink resistant properties and high tensile strength at the same time. Even when connected to another tube, the medical tube maintains the above-mentioned kink resistant properties and tensile strength. A medical tube is provided with at least one coil layer, a first outer layer provided outside the coil layer, and a second outer layer provided outside the first outer layer. The melting point of the material which forms the second outer layer is lower than the melting point of the material forming the first outer layer. The outer surface of the coil layer and the inner surface of the first outer layer are in contact with and affixed to each other in a slidable state.
