Indications for Use

The DSU-H and SSU-H Ultrafilters are intended to be used to filter EPA quality drinking water. The filters retain bacteria, viruses and endotoxin. By providing ultrapure water for patient washing and drinking, the filters aid in infection control. The filters produce water that is suitable for wound cleansing, cleaning of equipment used in medical procedures and washing of surgeon's hands. The filters are not intended to provide water that can be used as a substitute for USP sterile water.

Device Story

DSU-H and SSU-H Ultrafilters are hollow fiber ultrafiltration devices designed for in-line plumbing installation. The device utilizes a polysulfone hollow fiber membrane encased in an ABS housing to remove bacteria, viruses, and endotoxins from EPA-quality drinking water via size exclusion. The filters are used in clinical settings to provide ultrapure water for patient washing, drinking, wound cleansing, and cleaning of medical equipment. The device is operated by healthcare personnel. By reducing biological contaminants, the filters aid in infection control. The device does not require complex software or electronic processing; it functions as a passive mechanical filtration system.

Clinical Evidence

Bench testing only. Performance testing demonstrated retention capabilities: bacteria reduction > 10^11, virus reduction > 10^8, and endotoxin reduction > 10^5. These results were compared against the predicate device, showing equivalent or superior performance in contaminant removal.

Technological Characteristics

Hollow fiber ultrafilter; polysulfone membrane; ABS housing; size exclusion filtration principle; in-line plumbing installation; passive mechanical operation; no energy source; no software.

Indications for Use

Indicated for filtering EPA quality drinking water to provide ultrapure water for patient washing, drinking, wound cleansing, cleaning of medical equipment, and washing of surgeon's hands to aid in infection control. Not for use as a substitute for USP sterile water.

Regulatory Classification

Identification
