SORBENT SYSTEM FOR HEMODIALYSIS

Ash医疗公司开发了一种新的基于吸附剂的单通道药物

Ash Medical has developed a new sorbent-based, single-access hemodialysis machine which is safe, simple, and portable. The BioLogic-HD currently uses a plate dialyzer to actively pump blood while dialyzing the blood, and a Redy HiSorb column to regenerate dialysate. Previous research has proven that a thick sorbent suspension can flow through the screen supports of the plate dialyzer, replacing the Redy column. A sorbent suspension in the dialysate can produce higher clearances of uremic toxins, and use of sorbents with light density and small particle size, which are difficult to put into columns, such as zeolites. The current proposal is to further develop a sorbent suspension which will effectively remove uremic toxins, release appropriate substances, and minimize release of potentially harmful substances. This sorbent suspension will include powdered charcoal, and microcapsules which include calcium-sodium loaded zeolites and urease. In vitro tests will demonstrate the safety and efficacy of the sorbent suspension. If these tests are positive, an IDE will be prepared to allow clinical trials of the sorbent suspension in the BioLogic-HD system.
