摘要:
Disclosed is a flexible plastic hose (1) comprising a tubular hose body (2) having web portions (7) and a helical reinforcing rib (8), and a cuff (3a) mounted to an extremity (16) of the hose body (2) comprising a moulded end fitting (5a) bonded to the extremity (16a), and a stress relief element (4) with a first segment (S1) having an internal screw-thread (15) complementary to the helical reinforcing rib (8). Disclosed is also a method for making same, and use of the hose (1) as a medical hose.

摘要:
A method for producing polymeric tubing (20) which is resistant to permeation by organic material contained therein which has at least one region defined by a plurality of outwardly extending annular ridges. In this method polymeric material having a first outer diameter and composed of at least three overlying polymeric layers is introduced into a mold device upon exit of the tubular polymeric material from a suitable extrusion device. The mold surface of the mold device has at least one region defined by an annular depression (28) in an essentially cylindrical surface. Once the tubular material (20) is intruduced, it is expanded to a second outer diameter such that the tubular material (20) deformably contacts the mold surface. The corrugated tubular material then exist the mold device after completion of the expansion step.
摘要:
Bei einem flexiblen Schlauch, der eine mindestens aus einem ersten Innenschlauch (1) aus thermoplastischem bzw. elastomeren Material sowie einem Außenschlauch (4) bestehende Schlauchwandung aufweist, erstreckt sich eine abgeflachte Tasche (8) zur Aufnahme mindestens eines Energieleiters (10, 12, 13) im wesentlichen in Längsrichtung des Schlauches. Damit der Schlauch durch den Energieleiter, der auch nachträglich angebracht werden kann, möglichst wenig versteift wird, ist die Tasche (8) in Richtung zum Schlauchinneren elastisch dehnbar ausgebildet.
摘要:
One or more electric conductors (36, 236) in a flexible tube (10, 210) is protected from tensile and compressive forces exerted on or by the hose by providing an enclosure (32, 232) for the conductor(s) whose radial dimension (46, 246) provides a path for movement of the conductor(s) that is greater than any movement thereon exerted on or by the hose which might otherwise harm or break the conductor(s).
