Abstract
It is an object of the invention to provide a method of working an end portion of a tube for a medical instrument capable of being worked easily in a short period of time and capable of providing a smooth end portion of an outer surface thereof. According to a method of working an end portion of a tube for a medical instrument, first, a core member is inserted into a thermoplastic tube and arranged at a front end of the tube, a thermally contracting tube is covered to cover the front end of the tube, and heat is applied to the thermally contracting tube to contract at a position of the front end to thereby deform the front end of the tube by a contracting force of the thermally contracting tube and the heat from the thermally contracting tube.
Claims6
A method of working an end portion of a tube for a medical instrument comprising a thermoplastic tube, a tube end portion of the thermoplastic tube which is formed into a narrowed shape, the method comprising:
- inserting a core member into the tube for the medical instrument and arranging the core member at the end portion of the tube for the medical instrument;
- covering, with a thermally contracting tube, the end portion of the tube for the medical instrument in which the core member is inserted;
- and
- contracting the thermally contracting tube by applying heat at a position of the end portion of the tube for the medical instrument to thereby deform the end portion of the tube for the medical instrument by a contracting force of the thermally contracting tube and the heat from the thermally contracting tube.
A method of working an end portion of a tube for a medical instrument comprising a thermoplastic tube formed with a pipe line in an axial direction at inside of a tube peripheral wall, the pipe line which is closed by narrowing the end portion of the tube, the process comprising;
- inserting the core member to the tube for the medical instrument and arranging the core member at an end portion of the tube for the medical instrument;
- covering, with a thermally contracting tube, the end portion of the tube for the medical instrument in which the core member is inserted;
- and
- contracting the thermally contracting tube by applying heat at a position of the end portion of the tube for the medical instrument to thereby (i) deform the end portion of the tube for the medical instrument and (ii) close the end portion of the pipe line by a contracting force of the thermally contracting tube and the heat from the thermally contracting tube.
