The invention relates to a device for generating sterile water, in particular for unfolding or rinsing the During diagnostic and operative endoscopy, the bladder is introduced by introducing sterile water into the urethral i introduced instrument.

In medical interventions of various kinds, the use is of sterilized water has become a common practice. When using the sterile water, for example To rinse the bladder, the water taken from an irrigator is passed through a flexible hose using a suitable Instrument inserted through the uretra. The irrigator serves to quantize the water entering the bladder and at the same time to achieve the desired pressure. what by raising or lowering the irrigator, he follows.

For interventions of this type, for example, there is a wcr.ou, -liche Risk of iatrogenic infection the Ilarnweg or the male abnc that flows into it: -; '- and the genital organs. To prevent a transurc ϊ; ΐυ ·. ·· .ι · μι The use of high quality sterile water is a prerequisite for germ invasion. This is what happens in the hospital these days or prepared in the Pachpraxds itself from tap water. The tap water is filtered through the filter patronou;: nloitot, the filter ^ being arranged directly above the airtight closing lid of the irrigator vessel.: · ηπι. However, the water treated by such filter systems is not completely free of germs.

The object of the invention is therefore to provide a device to create, with which an increase in sterility can be achieved.

This achieves the invention in that between a Drinking water connection and a delivery, he keeps an ultrafiltration module and a UV sterilizer in series for the sterile * water are arranged.

This device produces sterile water of a quality such as it is required for most medical procedures.

Refinements of the invention are attached to the subclaims remove.

An embodiment of the invention will now be based on the figure explained in more detail:.

The drinking water to be cleaned is taken from a raw water connection 1 and first reaches the pre-filter 2, which has a pore size of approximately 5 micrometers and. thus larger impurities removed from drinking water.

The drinking water pre-cleaned in this way passes through a non-return valve 3 »so that no undesirable components can escape into the water supply network in the event of a possible suction back. Via a pressure reducing valve 4- to generate oinor. Operating overpressure of approx. 2 bar, the pre-cleaned (. '; To water reaches an ultrafiltration module 6 for further processing by means of known, bacterial abachoicioiut' η? ^Ι ] ϊ tcrinembi-an.en.

After this cleaning process, the water is sent to a UV sterilizer 7, in which any bacteria or viruses that may still be present are killed by ultraviolet light. '

Finally, the sterile water passes through a flow heater 8, where it is heated to the required use temperature.

The sterile water then reaches a dispensing container 10 via a solenoid valve 9. When the device is used for unfolding or rinsing the bladder, the dispensing container 10 is an irrigator, from which it is applied a tube or something similar, the sterile water into the urethra can be initiated.

The top of the dispensing container 10 can be hermetically sealed with a lid. At the dispensing end of the dispensing container there is a shut-off valve, not shown.

Additional devices are provided to ensure proper operation.

A manometer 5 monitors the operating pressure after the pressure reducing valve ^L v.

The disinfectant required in the ultrafiltration module 6 is sucked in via a connection 15. A solenoid valve 1Λ opens or closes the suction line, a non-return valve 1 17 prevents that as a result of a pressure drop between the dome water line area and the disinfection connection 15 water can reach the outside via the disinfection connection 15.

When the solenoid valve 14- releases the suction line, canoe the disinfectant by a pump 16, which is from a Motor 13 is driven, transported to the ultrafiltration module will.

For occasionally required rinsing of the Ultrafiltrnticm ;; module 6 is another solenoid valve 12, which the 1 / Ί · τ · connection to a drain 11 establishes for sewage disposal. This causes bacteria and viruses that are stuck to the surface and partially flushed pyrogens into the drain 11.

The solenoid valve 9 also has a further output connected to the drain 11, so that in the event of an imperfect quality of the sterile water this instead of in the Dispensing container 10 can be deflected into the drain 11.
