Device for checking endoscope channels
First Claim
1. A device for checking unobstructed flow through endoscope channels, the device comprising:
- a plurality of liquid containers that are each assigned to a channel that is to be checked, whereby each liquid container has a predetermined volume and an outlet that is capable of being connected to the channel that is to be checked;
a common compressed air source to which all the liquid containers are capable of being connected and which subjects liquid in the liquid containers to a predetermined pressure;
at least one sensor that registers whether a liquid level in one or more of the liquid containers has dropped below a predefined value; and
a control unit that measures the period of time within which the predetermined volume has flowed through the channel that is to be checked.

Abstract
In order to check endoscope channels, a predetermined quantity of liquid is led, at a predetermined pressure, through the channel that is to be checked, and the period of time for this is measured and evaluated. The predetermined quantity of liquid is determined via the volume of a liquid container whose outlet is capable of being connected to the channel that is to be checked. A compressed air source subjects the liquid in the container to a predetermined pressure. A sensor registers whether the liquid level in the container has dropped below a predefined value. A control unit measures the period of time within which the predetermined volume of liquid has flowed through the channel that is to be checked.
