AN INFUSION PUMP

摘要

An infusion pump has a housing (10) accommodating a pump finger mechani sm (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 guarantee a proper and positionally correct placement of the pump hose, one of the holders (16) comprises two oblique pins. The associated transition piece (15) of the pump hose (13) has two holes (18) with the same inclination angle as the pins. The other transition piece (20) is of a different structure so that the transition pieces cannot be mixed up . A longitudinal color strip on the pump hose indicates any twisting of the hose.
