Fresenius Medical Care Introduces Wireless Wetness Detector to Prevent Blood Loss During HHD


WALTHAM, Mass.—Fresenius Medical Care announced its introduction of the WetAlert wireless wetness detector, designed to detect venous needle displacement (VND) and prevent blood loss for dialysis patients at home. The WetAlert transmitter is the only device in the U.S. market that senses moisture at the venous needle site and sets off a process toautomatically stop the blood pump, close the venous clamp, display a visual alarm, and soundan audible alarm. The device transmits radio signals directly to the 2008K@home machine.  It is  unique and highly effective in design, and reusable for up to six months.

VND is a potential, serious complication related to dialysis therapy. If the venous needle becomes dislodged or disconnected from the patient’s vascular access, it could cause the patient to hemmorhage.  In just five to eight minutes, patients can lose 40-50 percent of their blood volume as a result of VND. Patients who lose more than 40 percent of their blood are more likely to suffer from permanent life-altering consequences such as stroke and other permanent disabilities. Instances of VND can also be expensive, and require emergency care or hospitalization.

“The WetAlert wireless wetness detector is a brand new option that may help reduce the fear of blood leaks during home dialysis because the blood pump stops on the 2008K@homemachine, thereby decreasing the amount of potential blood loss if VND occurs,” said Dr. JoseDiaz-Buxo, MD, FACP, chief medical officer at Fresenius Medical Care. Recently, the U.S. Foodand Drug Administration (FDA) cleared the WetAlert wireless wetness detector for use.
