1. A holding device for holding and storing at least one medical instrument during a processing and cleaning process, the holding device comprising:
a central feedline;
at least one line portion connected to a first end portion of the central feedline, at a free end of which a coupling device is arranged for coupling to the at least one medical instrument; and
a connector portion formed or arranged at a second end portion of the central feedline,
the connector portion being couplable to a pre-cleaning unit and a cleaning unit,
the second end portion of the central feedline comprising a venturi nozzle comprising a flow passage having a first portion with a first cross-section and a second portion with a second cross-section, wherein the first cross-section is greater than the second cross-section, and the flow passage reduces in size from the first cross-section to the second cross-section in a direction of fluid flow away from the connector portion, and an oil connector is formed at the second portion in a branching manner, wherein the oil connector is couplable to receive oil from an oil reservoir,
the at least one line portion comprising a valve device arranged in the at least one line portion, the valve device being closed in a basic position in which the at least one line portion and the at least one medical instrument are uncoupled, and the valve device being opened when the at least one medical instrument is coupled to the at least one line portion, and
wherein the venturi nozzle is configured such that a flow of air passing through the venturi nozzle in the direction of fluid flow generates a vacuum to draw oil from the oil reservoir, when connected to the oil connector, into the venturi nozzle.
