Definitions
- the invention relates to a fluid distributor for a treatment device for processing surgical instruments, in particular endoscopes.
- the invention further relates to a processing device for processing surgical instruments, in particular endoscopes, as well as a use of a corresponding fluid distributor in a processing device.
- endoscopes are used for the diagnosis and therapy of diseases.
- endoscopes and other surgical devices it is necessary that these surgical instruments be prepared after use in a patient, i. E. must be cleaned and disinfected.
- Surgical instrument reprocessing devices particularly endoscopes, have devices that clean and disinfect both the outer surfaces of the surgical instruments as well as the inner channels and channel systems using appropriate fluids. For this purge cycles are usually provided.
- the hygienic result in the preparation depends on the flow rates of a treatment fluid.
- the treatment fluid may be liquids or gases.
- a treatment device from Olympus Winter & Ibe GmbH, Hamburg is known for the treatment and disinfection of flexible endoscopes under the name ETD.
- ETD a treatment device from Olympus Winter & Ibe GmbH, Hamburg
- the channels of the endoscopes with a treatment fluid or rinsing, cleaning and / or disinfecting fluids flushed through.
- the preparation of surgical instruments after their use in a reprocessing device places high demands on the clinical area.
- the treatment typically includes the steps of washing, disinfecting and drying the endoscopes. Before disinfecting, one or two washing or pre-washing cycles are carried out. Followinged by rinsing with clear water and further drying steps. For washing and disinfecting, one or more chemicals are added to the washing medium or the cleaning agent for disinfecting. The exact dosage is important here.
- the channels of the surgical instruments are connected to a rinsing circuit of the treatment device.
- the channels are e.g. connected to an adapter of a receiving basket, in which the endoscope to be cleaned is arranged, so that subsequently connected to the cleaning end of the receiving device with the channels to be cleaned endoscope in the washing compartment of the treatment device channels with flushing channels of the flushing circuit or the adapter with a counterpart of the flushing become .
- Y-hose distributing pieces or directional valves For supplying fluids, in particular liquids and gases, to the channels to be cleaned or into the rinsing circuit, there are terminating valves, Y-hose distributing pieces or directional valves, which are diverted and brought together in a complex and often loss-making manner. In this case, the fluids flow through channels and can be distributed over several hoses. However, it is difficult to provide a uniform distribution and to provide moderate dosage.
