The 2008T BlueStar Hemodialysis Machine is indicated for acute and chronic dialysis therapy in a healthcare facility. Additional therapy options for patients receiving hemodialysis include: Isolated Ultrafiltration, Sustained Low Efficiency Dialysis (SLED), and low volume hemodialysis (patients weighing ≥ 20 kg). This machine accommodates the use of both low flux and high flux dialyzers. The SLED therapy option is not to be used for patients weighing ≤ 40 kg. The 2008T BlueStar Hemodialysis Machine is not to be used for plasma replacement therapies, for patients weighing less than 20 kg, or for renal therapies using substitution fluid.

bibag System (Optional):

The bibag system is used with three stream proportioning Hemodialysis Machines equipped with the bibag module such as the 2008T BlueStar Hemodialysis Machine and intended for use in bicarbonate hemodialysis for acute and chronic renal failure. The bibag is intended for extracorporeal bicarbonate hemodialysis according to a physician's prescription.

Crit-Line Clip Monitor (CLiC) (Optional):

The Crit-Line Clip Monitor is used with the 2008T BlueStar Hemodialysis Machine to non-invasively measure hematocrit, oxygen saturation and percent change in blood volume. The CLiC device measures hematocrit, percent change in blood volume and oxygen saturation in real time for application in the treatment of dialysis patients with the intended purpose of providing a more effective treatment for both the dialysis patient and the clinician. Based on the data that the monitor provides, the clinician/nurse, under physician direction, intervenes (i.e., increases or decreases the rate at which fluid is removed from the blood) in order to remove the maximum amount of fluid from the dialysis patient without the patient experiencing the common complications of dialysis which include nausea, cramping and vomiting.

The 2008T Machine is an electromechanical device. Software controls the machine during hemodialysis treatment, including fluid flow, mixing, heating, and alarms. The 2008T Machine provides hemodialysis treatment by controlling and monitoring both the dialysate circuit and the extracorporeal blood circuit. The machine pumps blood from the patient's body through an extracorporeal circuit, one component of which is the dialyzer. The dialyzer contains a semi-permeable membrane that uses diffusion to transfer toxins and ultrafiltration to transport excess water from the blood into the dialysate circuit. In this separate dialysate circuit, the dialysate concentrates are mixed with purified water, heated, degassed, and delivered to the dialyzer through platinum cross-linked silicone tubing. Balancing chambers control the dialysate during treatment. During treatment, the extracorporeal blood circuit is monitored for venous and arterial blood pressures as well as for the presence of air and blood.

The provided text is a 510(k) summary for the Fresenius Medical Care 2008T BlueStar™ Hemodialysis Machine. This document outlines the device description, indications for use, comparison to a predicate device, and performance data to demonstrate substantial equivalence to a legally marketed device.

However, the information provided does not describe acceptance criteria and a study that proves a device meets those criteria in the context of an Artificial Intelligence (AI) or machine learning (ML) enabled medical device.

The document is for a hemodialysis machine, which is an electro-mechanical device, not an AI/ML device for diagnostic or predictive purposes. The "performance data" sections are related to physical and biological safety, functional verification, and material compatibility of the hemodialysis machine itself, not validation of an AI/ML algorithm's performance on a dataset.

Therefore, I cannot extract the requested information (table of acceptance criteria with reported device performance, sample sizes for test/training sets, data provenance, number of experts for ground truth, adjudication methods, MRMC study details, standalone performance, type of ground truth, training set size, and training ground truth establishment) as this document does not pertain to an AI/ML enabled medical device study.

To answer your request, I would need a document describing the validation of an AI/ML medical device.

The HDF Assist Module is indicated for use, with the Fresenius 2008K2, and 2008T dialysis machines, for treatment of adult patients with acute or chronic renal failure or whenever hemodiafiltration is physician.

The HDF Assist Module works in conjunction with a qualified host high permeability (UF controlled) hemodialysis machine and its accessories (i.e., bloodlines, dialysate, concentrates, etc.), the HDF Assist Module accessories (HDF Infusion Set and Substitution Filter), appropriately purified water and ultrapure dialysate for hemodialysis, and a high permeability hemodialyzer / hemodiafilter (i.e., the OLPür™ MD 220 Hemodiafilter).

The HDF Assist Module is a software controlled; electro-mechanical medical device designed to work in combination with a sterile single use HDF Infusion Set (an accessory included in this submission) and a qualified host high permeability (UF controlled) hemodialysis machine, which produces ultrapure dialysis fluid. Upon installation the HDF Assist Module is connected to the host dialysis machine's IV Pole and plugged into a Standard 120VAC electrical mains power source.

To perform a hemodiafiltration treatment with the HDF Assist Module, the device is used in unison with the accessory sterile, single-use HDF Infusion Set to generate and control the online substitution fluid for hemodiafiltration from the ultrapure dialysis fluid of the host dialysis machine. The sterile HDF Infusion Set consists of an 0.25 m² ultrafilter, tubing including a peristatic pump segment, pressure sensor pods, and check valves.

The HDF Infusion Set is primed prior to treatment to remove air from the Set. The HDF Infusion Set is placed on the unit in preparation for each HDF treatment. A peristatic pump in the HDF Assist Module pumps a preset amount of ultrapure dialysis fluid produced by the host dialysis machine via the peristatic pump segment in the HDF Infusion Set. The dialysis fluid is drawn from an input dialysate Hansen T-connector and pumped through a sterile single use 0.25 m² ultrafilter in the HDF Infusion Set. The rest of the dialysis fluid flows outside of the fiber in the OLPūr™ MD 220 Hemodiafilter as in conventional hemodialysis.

During priming and treatment, the ultrafilter in the HDF Infusion Set removes bacteria and endotoxins from the ultrapure dialysis fluid, thereby generating an injectable quality substitution (replacement) fluid of correct electrolyte composition. The ultrafiltered substitution fluid flows through tubing connected to the extracorporeal circuit where it is infused as part of the hemodiafiltration treatment at the MD220 Mid-Dilution port. The ultrafilter is 100% tested in a production integrity check during manufacture.

This document is a 510(k) Premarket Notification for the Nephros, Inc. HDF Assist Module, HDF Infusion Set, and Substitution Filter. The acceptance criteria and the study that proves the device meets them are primarily described within the "Assessment of Non-Clinical Performance Data/Substantial Equivalence" section.

Here's an analysis based on the provided text:

Key Takeaway: This 510(k) submission is for modifications to an existing cleared device (K112314, OLPūr™ H2H Hemodiafiltration Module). Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are focused on demonstrating that the modified device remains substantially equivalent (safe and effective) to the predicate device, rather than proving a de novo device's initial safety and effectiveness. No clinical studies were performed for this submission.

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a modification submission, the "acceptance criteria" are generally compliance with relevant standards and demonstration of continued substantial equivalence. The "reported device performance" refers to the successful completion of various tests.
