| 发明名称 | Method for manufacturing a medical tube | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method for manufacturing a medical tube, the medical tube including a coil layer on an inside of an outer layer tube made of a resin, the method comprising: 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, wherein the outer layer tube comprises a thermoplastic elastomer, and the outer layer tube has an inner diameter shrinkage ratio of 1% or more and 10% or less during the heating at the molding temperature. | ||
