Abstract
A dialyzer reprocessing device and method are disclosed. The device and method are of the type which include a dialyzer and means for cleaning the dialyzer by treatment with fluids. Included is a treating device for modifying the fluids prior to introduction into the dialyzer. The treating device includes means for directly injecting into the fluids electromagnetic radiation having a preselected frequency through a nonelectrically insulated conductor.
Claims16
In a dialyzer reprocessing device of the type which includes a dialyzer and means for cleaning the dialyzer by treatment with fluids, and a conduit for conveying the fluids to the dialyzer, the improvement comprising a treating device for modifying the fluids prior to introduction thereof into said dialyzer, said treating device comprising means for directly injecting into said fluids electromagnetic radiation having a preselected frequency through a non-electrically insulated conductor.
A dialyzer reprocessing device, comprising:
- a dialyzer;
- conduit means for conveying cleaning, rinsing and disinfecting fluids to said dialyzer;
- said dialyzer arranged to receive said fluids and having an outlet conduit through which said fluids are discharged;
- and
- treatment means for treating said fluids to be received by said dialyzer through said conduit means by directly injecting into said fluids electromagnetic radiation having a preselected frequency through a non-electrically insulated conductor.
An apparatus for reprocessing or otherwise cleaning filtering systems, comprising:
- filter means containing at least one filtration membrane module, said filter means including inlet means, first outlet means for concentrate and second outlet means for permeate;
- cleaning means for said filter means including means for delivering cleaning fluids under pressure to said inlet means of said filter means;
- said cleaning means including a first conduit interconnecting said delivery means and said first outlet means and a valve means for selectively directing said fluids from said delivery means to said inlet means or to said first outlet means through said first conduit means;
- and
- electromagnetic treatment means for directly injecting into said fluids through said first conduit means electromagnetic radiation of a preselected frequency through a non-electrically insulated conductor.
A method for enhancing the lifetime of filters in a system in which fluids are fed into filters, comprising the steps of:
- (a) providing a filter system, a supply of fluids and conduit means for conveying the fluids to the filters;
- (b) generating an electromagnetic signal at a preselected frequency;
- (c) injecting said electromagnetic signal into said fluids at a location prior to their entering the filter system, through a nonelectrically insulated conductor in electrical contact with the fluids;
- and
- (d) said preselected frequency is selected from the range of 20 to 60 MHz.
A method of extending the reuse of dialyzers, comprising the steps of:
- (a) providing one or more dialyzers to be reprocessed for reuse arranged to receive cleaning and disinfecting fluids;
- (b) subjecting said dialyzers to said cleaning fluids;
- (c) generating an electromagnetic signal at a preselected frequency;
- (d) injecting said electromagnetic signal into said fluids at a location prior to their entering a filter, through a conductor in electrical contact with the fluids;
- and
- (e) said preselected frequency is selected from the range of 20 to 60 MHz.
A filtration device, comprising:
- a filter;
- conduit means for conveying feed fluids to a filter;
- said filter being arranged to received said fluids and having an outlet through which said fluids are discharged;
- and
- treatment means for treating said fluids to be received by said filter by directly injecting into said fluids electromagnetic radiation having a preselected frequency through a non-electrically insulated conductor.
