Abstract

A holding device for holding and supporting at least one medical instrument, more specifically a surgical handpiece. The holding device includes a central feedline, at least one line portion of which is connected to the end portion of a central feedline. At least one surgical handpiece can be coupled to the line portion. The holding device also includes a connector portion formed on another end portion of the central feedline. The connector portion can be coupled to a preliminary cleaning unit, more specifically a water/compressed air gun, and a cleaning unit, more specifically a filter unit connected to a rinsing line.

First claim

The invention claimed is:

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.

2. The holding device according to claim 1 , wherein the connector portion is configured as a Luer lock connection.

3. The holding device according to claim 1 , wherein at the second end portion of the central feedline a puncture spike is arranged which is couplable to an oil unit.

4. The holding device according to claim 3 , wherein the puncture spike is configured to selectively couple to a removable oil reservoir.

5. The holding device according to claim 1 , wherein the connector portion is couplable to an oil unit.

6. The holding device according to claim 1 , wherein the second cross-section of the flow passage comprises a minimum cross-section of the flow passage.

7. A processing and cleaning system comprising:
the holding device according to claim 1 ;
a pre-cleaning unit configured to be connected to the connector portion of the holding device; and
an oil reservoir configured to be connected to the oil connector of the holding device.

8. 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 at which an oil connector is formed in a branching manner which is couplable to an oil reservoir, and
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,
wherein at the second end portion of the central feedline a puncture spike is arranged which is couplable to an oil unit, and
the venturi nozzle is configured such that a flow of air passing through the venturi nozzle in a direction of fluid flow generates a vacuum to draw oil from the oil reservoir, when connected to the oil connector, into the venturi nozzle.

9. The holding device according to claim 8 , wherein the puncture spike is configured to selectively couple to a removable oil reservoir.
