Abstract
In an apparatus for producing sterile water an ultrafiltration module and an ultraviolet steriliser are arranged in series between an untreated water connection and a dispensing container for the sterile water.
Description
SPECIFICATION
Apparatus for producing sterile water
The present invention relates to an apparatus for producing sterile water, more especially to be used for distending or flushing the bladder in diagnostic and operative endoscopy by means of introducing sterile water through an instrument inserted in the urethra.
In surgical operations of different kinds, the use of sterile water has become conventional practice,
When using sterile water, for example, for flushing the bladder, the water extracted from an irrigator is introduced through the urethra by means of a suitable instrument passed through a flexible tube.
The irrigator thus serves for the quantization of the water entering the bladder and at the same time for obtaining the required water pressure which occurs by raising or lowering the irrigator.
In operations of the kind referred to, there is considerable risk in the possibility of an iat
rogenous infection of the urinary passages orthe male adnexa and the genital organs. To prevent a transurethral germ invasion, the use of high quality sterile water is an essential condition. This water is nowadays prepared by using sterile filters in the hospital or in the professional practice itself from mains water. The mains water is thus conducted over filter cartridges, whereby the filter may be located directly above the hermetically sealed cover of the irrigator. Water prepared in such a manner, however, is not perfectly sterile.
It is an object of the present invention to provide an apparatus which permits an increased sterility to be obtained.
According to the present invention there is provided an apparatus for producing sterile water, more especially to be used for distending or flushing the bladder in diagnostic and operative endoscopy by means of introducing sterile water through an instrument inserted in the urethra, in which an ultrafiltration module and an ultravoilet steriliser are arranged in series between an untreated water connection and a dispensing containerforthe sterile water.
This apparatus produces sterile water of a quality as required for most surgical operations.
The present invention wi!l be further illustrated, by way of example, with reference to the accompanying drawing in which the single Figure is a schematic view of an apparatus in accordance with the invention.
The water to be purified is extracted from an untreated water connection 1 and first passes through a preliminary filter 2 which has a pore size of about 5 micrometres and hence removes larger size impurities from the water.
The water pre-purified in such a manner then passes through a non return valve 3, to prevent undesired components from escaping into the water mains during a possible reverse suction occurring.
The pre-purified water, via a pressure reduction valve 4 to produce an operational excess pressure of about2 barthen passes through an ultrafiltration module 6 for further purification by means of a bacteria separating filter membrane known perse.
After this purification, the water is supplied to an ultravbilet steriliser 7 in which any possibly still existing bacteria or viruses are killed by ultraviolet.
light. Finally, the sterile water passes through a throughflow heater 8 where it is heated to the required temperature of use.
The sterile water via a magnetic valve 9 then arrives at a dispensing container 10. When using the apparatus for distending or flushing the bladder, the dispensing container 10 is an irrigator from which via a tube or the like the sterile water can be introduced into urethra.
The upper surface of the dispensing container 10 is hermetically sealable by a cover. A stop valve, not shown, is provided at the dispensing end of the dispensing container.
To ensure proper operation, further apparatuses are also provided.
A pressure gauge 5 monitors the operating press ure and is located downstream of the pressure reduction valve 4.
The disinfectant required in the ultrafiltration module 6 is supplied by induction from a connection 15. A magnectic valve 14 respectively opens and closes the induction pipe, a non-return valve 17 prevents water being able to reach the outer atmosphere vai the disinfectant connection 15 due to a pressure drop between the water mains and the disinfectant connection 15.
When the magnetic valve 14 opens the inductipn pipe, the disinfectant can be fed to the ultrafiltration module through a pump 16 which is driven buy a motor 13.
A further magnetic valve 12, which produces the connection to an outflow 11 for the waste water removal is used for the occasionally required flushing of the ultrafiltration module 6. By this means bacteria, viruses and pyrogens stuck to the surface are flushed into the outflow 11.
The magnetic valve 9 is also connected by way of a further exit to the outflow 11, so that in the event of an unsatisfactory quality of sterile water being supplied, the latter can be diverted into the outflow 11 instead of into the dispensing container 10.

ultrafiltration module and an ultraviolet steriliser are arranged in series between an untreated water connection and a dispensing container for the sterile water.
2. Apparatus as claimed in claim 1, in which a preliminary filter is provided directly after the untreated water connection.
3. Apparatus as claimed in claim 1 or 2, in which the dispensing container is an irrigator.
