Title
(EN) MEDICAL TUBULAR BODY TRANSPORT DEVICE AND METHOD FOR PRODUCING SAME
(FR) DISPOSITIF DE TRANSPORT DE CORPS TUBULAIRE MÉDICAL ET SON PROCÉDÉ DE PRODUCTION
(JA) 医療用管状体搬送装置およびその製造方法
Abstract
(EN)
Provided are: a medical tubular body transport device which decreases friction resistance between an outer tube and other objects, reduces the operation resistance when pulling the outer tube, is easy to handle, and makes it possible to stably hold a medical tubular body therein. A device which transports a medical tubular body (2) into a living body and has an outer tube (10) having the medical tubular body (2) positioned in the internal cavity thereof, a pulling member (20) connected to the outer tube (10), a pulling member storage tube (30) having the pulling member (20) inserted into the internal cavity thereof, a guide wire tube (80) having a guide wire inserted into the internal cavity thereof, a covering tube (50) having the pulling member storage tube (30) and the guide wire tube (80) positioned in the internal cavity thereof, and a protective tube (60) having the covering tube (50) positioned in the internal cavity thereof, wherein: the pulling member storage tube (30) and the guide wire tube (80) are secured to one another on the distal side of the distal end (50a) of the covering tube (50) and on the proximal side of the proximal end (10b) of the outer tube (10); and the pulling member storage tube (30) and the guide wire tube (80) are not secured to one another in the section where the covering tube (50) is present.
