Intended Use
The DIMI RRT System is indicated for use in patients with acute and/or chronic renal failure, with or without fluid overload, who require hemodialysis, hemofiltration, or ultrafiltration. The DIMI RRT System is intended for use in a clinical setting or in a home environment by a trained and qualified patient or caregiver. The DIMI RRT System is intended to be used with a prescription from a physician.
Device Story
DIMI RRT System is a portable hemodialysis machine for acute/chronic renal failure treatment. It performs hemodialysis, hemofiltration, or ultrafiltration. Device operates in clinical or home settings; managed by trained patients, caregivers, or clinicians. System processes blood and dialysate flows; monitors treatment parameters via integrated software. Output includes real-time treatment data and status alerts to ensure therapy adherence and patient safety. Device facilitates renal replacement therapy outside traditional clinical environments, potentially improving patient quality of life and treatment flexibility.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by bench testing, including performance verification, electrical safety, electromagnetic compatibility, and software validation.
Technological Characteristics
Portable hemodialysis system for home/clinical use. Utilizes high permeability hemodialysis technology. Includes integrated software for treatment monitoring and control. Connectivity features for data management. Sterilization and biocompatibility standards applied to fluid path components.
Indications for Use
Indicated for patients with acute and/or chronic renal failure, with or without fluid overload, requiring hemodialysis, hemofiltration, or ultrafiltration. Intended for use in clinical or home settings by trained patients or caregivers under physician prescription.
Regulatory Classification
Identification
A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.). (3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).
