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.
