| 摘要 |
The present invention is directed to a medical tube set comprising a tube 10 and a stylet 20 that improves the insertability of tube 10. The stylet 20 structure comprises an inner core 21 that can be inserted into tube 10, an apical tip 22 that is affixed to the apical end of inner core 21, and a movable expansion member 23 that can move between apical tip 22 of inner core 21 and stop 24 that is provided at a predetermined distance from apical tip 22. An engagement 22a is formed at the posterior end of apical tip 22, and is able to engage the apical end 11b of tube 10. By positioning movable expansion member 23 within apical end 11 b of tube 10, apical end 11b can expand radially outwards so that apical tip 22 can pass through. |
