Definitions

• the invention relates to a method for rinsing endoscope channels of an endoscope.
• the invention further relates to a device for flushing endoscope channels of an endoscope and the use of a corresponding device.
• a measuring device for example a flow meter or a pressure gauge, is provided in the flushing line.
• the channels are rinsed and tested one at a time or simultaneously.
• the processing time is significantly reduced if the channels are flushed in parallel.
• the effort for the flow test increases with the number of channels, because a measuring device with associated electronics must be provided per channel.
• the invention has for its object to keep the processing time for cleaning an endoscope with multiple endoscope channels as short as possible and the necessary effort as low as possible.
• a flow rate or a pressure of the rinsing agent is measured or determined by means of the testing device.
• Pressure and flow rate are particularly dependent on the diameter of an endoscope channel, which changes with partial or complete blockage, in particular reduced.
• the measurement or determination of pressure and / or flow rate, in particular a volume flowing per unit time thus ensures that a blockage of an endoscope or an endoscope channel is reliably detected.
• the first test device and / or the second test device preferably comprise a flow meter or a pressure gauge.
• one of the two test devices may comprise a flow meter and the other of the two test devices may comprise a pressure gauge.
• the second test device in the form of a flow meter, may preferably measure the total flow through the other channels.
• a flushing agent distributor is designed as a flushing agent chamber or as a flushing agent reservoir. This makes possible a particularly compact flushing agent distributor with very short line paths, which for reasons of hygiene are preferable to longer and / or branched lines.
• the object underlying the invention is also achieved by the use of a device according to the invention in a method according to the invention.
• the volume of flushing agent measured or determined by means of the flowmeter 28 corresponds to the amount of flushing agent flowing through the endoscope channel connected to the flushing channel 30b. If this endoscope channel is completely or partially blocked, the volume of flushing agent flowing through the endoscope channel per unit of time changes, which can be measured on the flowmeter 28. By means of the flow meter 28 or the test device 24, the endoscope channel 30b can thus be checked for blockage.
• all other endoscope channels are supplied with rinsing agent via the second supply line 23 and the second distribution chamber 22 and are cleaned or rinsed.
• all endoscope channels are individually and successively connected to the first distribution chamber 20 and checked by the test device 24 in the manner described for blockages out.
• the respective other endoscope channels are connected to the second distribution chamber 22 and are rinsed.
• one line shows a combination of the simultaneously set positions of all the change-over valves 32a-d, and one column shows the positions consecutive for a specific change-over valve 32a, 32b, 32c, 32d.
• position A means that the corresponding endoscope channel is checked for blockage
• position B means that the corresponding endoscope channel is flushed.
• a configuration 5 may be set in which, for example, all the switching valves 32a-d are in position B and Thus, all endoscope channels are rinsed once again for any remaining time required.
• FIG. 2 schematically shows a circuit diagram of a further flushing device 1 according to the invention, from which some further developments and modifications of the invention can be seen by way of example.
• the supply line 23 also has a test device 24, this test device comprising a flow meter 28 with the already described in connection with FIG. 1 operation.
• the switching valve 32a of the exemplary flushing device 1 shown in FIG. 2 is designed as a 3/2-way valve, wherein in the first position flushing agent from the distributor 20 and in the second position flushing agent from the distributor 22 is directed to a flushing channel 30a, on which in turn an endoscope channel is or will be connected.
• the operation of the switching valve 32a thus substantially corresponds to the switching function described in connection with FIG.
• the switching valve 32b is designed as a 3/3-way valve. In a In the first position, rinsing agent is conducted from the distributor 20 into the rinsing channel 30b. In a second position, rinsing agent is conducted from the distributor 22 into the flushing channel 30b. In a third position, the valve is closed, ie no flushing agent flows.
• the flushing channel 30b is thus a switch-off flushing channel, which can remain free, for example, when the endoscope to be flushed has fewer endoscope channels than flushing channels 30a-c are present. This functionality is particularly advantageous in a flushing device with numerous, for example more than five, flushing channels.
• An exemplary endoscope has three endoscope channels of different diameters.
• the thinnest endoscope channel i. the endoscope channel with the smallest cross-section or the greatest flow resistance
• the thickest endoscope channel or the endoscope channel with the lowest flow resistance is connected, for example, to the lockable flushing channel 32b and the third endoscope channel to the flushing channel 32a.
• position A means that the corresponding endoscope channel is connected to the first distributor 20
• position B assumes that the endoscope channel is connected to the second distributor 22, and position C, which is provided only for the switching valve 32b, that the corresponding endoscope channel of both distributors 20, 22 and thus of the detergent supply is completely separated.
• one of the endoscope channels is connected one after the other to the first distributor 20 one after the other and is connected by means of the first test device 24 in the supply line 21, i. be checked for blockage by means of the check valve 26 and the pressure gauge 25.
• the other two endoscope channels are supplied with rinsing agent via the second distributor 22 and rinsed.
• one of the endoscope channels is connected one after the other to the second distributor 22 one by one, and by means of the second testing device 24 in the supply line 23, i. be checked for blockage by means of the flow meter 28.
• the switching valve 32b is in the position C, in which the corresponding endoscope channel is separated from the detergent supply.
• This is, for example, the endoscope channel with the lowest flow resistance, which usually requires the least flushing time for proper cleaning. In this way, detergent is saved.
