The device description and performance studies focus on the chemical composition and physical properties of a dry powder concentrate for hemodialysis, with no mention of AI or ML technologies.
Yes
The device is clearly indicated for use in bicarbonate hemodialysis, which is a therapeutic treatment for acute and chronic renal failure or intoxication.
No
This device is a cartridge containing sodium bicarbonate, which is used to prepare a solution for hemodialysis. Hemodialysis is a treatment for renal failure, not a diagnostic procedure. The device facilitates the treatment, it does not diagnose a condition.
No
The device description clearly states it is a "dry powder concentrate used to prepare sodium bicarbonate concentrate solution" contained within a "polypropylene cartridge." This is a physical, hardware-based medical device, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "bicarbonate hemodialysis for acute and chronic renal failure, or intoxication with dialyzable substances." This describes a therapeutic treatment process, not a diagnostic test performed in vitro (outside the body) on biological samples to diagnose a condition.
- Device Description: The device is a "dry powder concentrate used to prepare sodium bicarbonate concentrate solution for use in conventional hemodialysis." This is a component used in the hemodialysis process itself, which is a treatment.
- Lack of Diagnostic Elements: The description and performance studies focus on the chemical composition, physical properties, and functionality of the cartridge in preparing the hemodialysis solution. There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information about a patient's condition.
IVD devices are specifically designed to perform tests on samples like blood, urine, or tissue to provide information for diagnosis, monitoring, or screening. This device's function is to provide a necessary component for a therapeutic procedure.

Device Description
The Di-Chem Hemo-Lyte C sodium bicarbonate cartridge for hemodialysis is a dry powder concentrate used to prepare sodium bicarbonate concentrate solution for use in conventional hemodialysis. The Hemo-Lyte C cartridge is a single use/non-refillable polypropylene cartridge containing a measured amount of sodium bicarbonate (USP Hemodialysis grade) which enables the online preparation of bicarbonate hemodialysis solution on commercially available hemodialysis machines/monitors equipped for use with bicarbonate cartridges. Testing has demonstrated that this device can be safely used on the Nipro Surdial DX with a maximum dialysate flow rate of 600 ml for up to 4 hours. Use with other machines and/or outside the testing parameters have not been verified and therefore is not recommended.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Summary of Non-Clinical Tests: In vitro testing was performed to verify the chemical composition of the proposed device was identical to that of the predicate devices and within the ranges set forth by ANSI/AAMI 13958:2014. The results of the testing met the requirements of ANSI/AAMI 13958:2014, confirming the device met listed range requirements and is chemically equivalent to predicate devices.
Transportation Testing: Performed per ASTM D4169-16, DC13, Assurance Level I, Schedules: A, C, F, I, E, and A. Results indicate the device can be shipped and transported safely and effectively.
Biocompatibility Testing: Performed in accordance with ISO 10993 requirements, including Cytotoxicity, Sensitization, Acute Systemic Toxicity, ASTM Hemolysis, Material Mediated Pyrogenicity, Intracutaneous Reactivity, Chemistry Characterization, Biological Evaluation Report, and Toxicological Risk Assessment.
Sterilization and Shelf-Life Testing: The device is non-sterile when used. Shelf-life verification testing on aged product ensured the device maintained the labeled value for sodium bicarbonate and conformed to ANSI/AAMI 13958:2014 standards at the conclusion of the storage period.
Bench Testing: Evaluated 12 total cartridges (3 samples from each of the proposed weight sizes) for physical, chemical, and non-clinical aspects to meet requirements for "sodium bicarbonate cartridges" for use on the Nipro SURDIAL DX Hemodialysis System. Tests included: Visual inspection, confirmation of proper cartridge fit to machine, concentration of bicarbonate in initial and final dialysate samples, initial and final pH of dialysate sample, initial and final conductivity of dialysate sample. Conductivity and pH values were also recorded every 30 minutes during the 4-hour test cycle. Results showed the device functions as intended with the Nipro SURDIAL DX Hemodialysis machine.
Endotoxin Analysis on Device Contents: Performed on 60 total test samples (30 from pre-stability and 30 from shelf-life study) from three different lots of sodium bicarbonate in accordance with ANSI/AAMI 13958:2014. All samples were below the stated limit of 0.5 EU/ml.

§ 876.5820 Hemodialysis system and accessories.
(a)
Identification. A hemodialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. Blood from a patient flows through the tubing of the extracorporeal blood system and accessories to the blood compartment of the dialyzer, then returns through further tubing of the extracorporeal blood system to the patient. The dialyzer has two compartments that are separated by a semipermeable membrane. While the blood is in the blood compartment, undesirable substances in the blood pass through the semipermeable membrane into the dialysate in the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the dialyzer.(1) The extracorporeal blood system and accessories consists of tubing, pumps, pressure monitors, air foam or bubble detectors, and alarms to keep blood moving safely from the blood access device and accessories for hemodialysis (§ 876.5540) to the blood compartment of the dialyzer and back to the patient.
(2) The conventional dialyzer allows a transfer of water and solutes between the blood and the dialysate through the semipermeable membrane. The semipermeable membrane of the conventional dialyzer has a sufficiently low permeability to water that an ultrafiltration controller is not required to prevent excessive loss of water from the patient's blood. This conventional dialyzer does not include hemodialyzers with the disposable inserts (Kiil type) (§ 876.5830) or dialyzers of high permeability (§ 876.5860).
(3) The dialysate delivery system consists of mechanisms that monitor and control the temperature, conductivity, flow rate, and pressure of the dialysate and circulates dialysate through the dialysate compartment of the dialyzer. The dialysate delivery system includes the dialysate concentrate for hemodialysis (liquid or powder) and alarms to indicate abnormal dialysate conditions. This dialysate delivery system does not include the sorbent regenerated dialysate delivery system for hemodialysis (§ 876.5600), the dialysate delivery system of the peritoneal dialysis system and accessories (§ 876.5630), or the controlled dialysate delivery system of the high permeability hemodialysis system § 876.5860).
(4) Remote accessories to the hemodialysis system include the unpowered dialysis chair without a scale, the powered dialysis chair without a scale, the dialyzer holder set, dialysis tie gun and ties, and hemodialysis start/stop tray.
(b)
Classification. (1) Class II (performance standards) for hemodialysis systems and all accessories directly associated with the extracorporeal blood system and the dialysate delivery system.(2) Class I for other accessories of the hemodialysis system remote from the extracorporeal blood system and the dialysate delivery system, such as the unpowered dialysis chair, hemodialysis start/stop tray, dialyzer holder set, and dialysis tie gun and ties. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.
