The device description lists standard water purification components and the performance studies focus on water quality analysis against established standards, with no mention of AI/ML technologies or methodologies.
No.
This device purifies water for hemodialysis treatment, but it is not directly applied to the patient to treat a disease or condition. Its function is to prepare the water used in the therapeutic process, not to deliver the therapy itself.
No
This device is a water purification system for hemodialysis, which purifies water rather than diagnosing medical conditions. The performance studies and tests described relate to the quality of the purified water, not the diagnosis of patients.
No
The device description clearly outlines a physical water purification system with multiple hardware components (booster pump, filters, tanks, alarms, etc.). It is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "Purify water used in hemodialysis treatment." This is a water purification system for a medical procedure, not a device used to examine specimens derived from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a water purification system with various components for filtering and treating water. It does not describe a device that analyzes biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing patient samples, detecting analytes, or providing diagnostic information. The performance testing focuses on the quality of the purified water, not on the analysis of biological specimens.
Therefore, this device falls under the category of a medical device used in the treatment process, but not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical tests: Following the installation of the water purification system a sample of the product water produced by the system is taken and analyzed by an independent laboratory to determine the level of contaminants in the water. These laboratory results are compared with the maximum permitted level for each contaminant in order to determine that the product water purified by the system meets the customer's requirements for purified water. This method was also used by the predicate device to demonstrate compliance with recognized acceptable contaminant levels in product water. The performance test results of the candidate device complied with the requirements of: AAMI Standard RD62:2001, Water Treatment Equipment for Hemodialysis Applications; USP: Total Organic Carbon.

§ 876.5665 Water purification system for hemodialysis.
(a)
Identification. A water purification system for hemodialysis is a device that is intended for use with a hemodialysis system and that is intended to remove organic and inorganic substances and microbial contaminants from water used to dilute dialysate concentrate to form dialysate. This generic type of device may include a water softener, sediment filter, carbon filter, and water distillation system.(b)
Classification. Class II (special controls). The device, when it is a water purification subsystem disinfectant, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.
