  • Apparatus for introducing liquids and/or elongated elements into a body cavity
    Patent number: 4838873
    Abstract: The apparatus for medical purposes comprises a sleeve-type catheter hub (10) having a cylindrical longitudinal channel (11) and a flexible catheter capillary (24) which, through an orifice portion (11a) of the longitudinal channel (11) extends into an expanded intermediate section (11c) of the longitudinal channel (11). The catheter capillary (24) includes a thicker head portion (23) tightened in the expanded intermediate section (11c) of the longitudinal channel (11) by an annular shoulder (22) of a radial annular collar (20) which is formed by ultrasonic welding into the wall of the longitudinal channel (11). To obtain a stepless passage of the cylindrical channel (11), an adapter (18) with a conical passage (19) is joined by press fit to the annular collar (20). The catheter capillary (24) is firmly anchored. In addition, the conical passage (19) serves as an insertion aid for a probe or the like.
