Abstract: An infusion pump has a housing (10) accommodating a pump finger mechanism (12). The pump finger mechanism (12) acts on a pump hose (13) fastened at holders (16, 21) of the housing. The pump hose (13) is supported by a door (24). In order to facilitate proper and positionally correct placement of the pump hose, one of the holders (16) includes an oblique pin. The associated transition piece (15) of the pump hose (13) has a hole (18) with the same inclination angle as the oblique pin. The other transition piece (20) is of a different structure so that the transition pieces cannot be mixed up. A longitudinal color strip (29) on the pump hose is provided to visually indicate any twisting of the hose.

Abstract: A dividable short catheter tube made of a modifying polymer intermixed with, or inserted into, a base polymer. The modifying polymer is usually one which is incompatible with the base polymer.The dividable short catheter tube is readily tearable longitudinally so that it can be removed from around a flexible catheter after the flexible catheter has been guided into a patient by means of the short catheter previously positioned in a body puncture.The tube can be extruded from a mixture of the two polymers or it can be extruded with modifying polymer longitudinal strips in walls of the base polymer.
