Intended Use

The SmartHDM-510 system may be used by hemodialysis personnel to test the conductivity, temperature, pH and flow of the dialysate solution used with hemodialysis delivering systems. The SmartHDM-510 system may also be used to test the conductivity/temperature and pH of acid and sodium bicarbonate dialysate concentrates and water used in hemodialysis applications. The intended use is limited to periodic use for installation and maintenance of hemodialysis delivering systems and does not include the daily monitoring of hemodialysis delivering systems prior to treatment.

Device Story

SmartHDM-510 is a hemodialysis service system for installation and maintenance of hemodialysis delivery equipment. It utilizes external sensors (HDU-Sensors, HDM-Sensor Modules, 90XL-Sensors) to measure conductivity, temperature, pressure, pH, and flow. Data is transmitted to an Android-based display module running the SmartHDM-510 App. The system provides high-resolution graphical displays, statistical values, and user hints to assist technicians in identifying errors and verifying system conditions. Used by hemodialysis personnel in clinical settings; output allows technicians to perform precise adjustments and maintenance on dialysis machines, ensuring accurate dialysate composition and system performance, ultimately supporting safe patient treatment.

Clinical Evidence

Bench testing only. Performance verified through software testing, code reviews, system verification/validation, and electrical/electromagnetic safety compliance. Testing addressed user interface, usability, sensor communication, and measurement accuracy against specifications.

Technological Characteristics

System comprises external sensors (conductivity, temperature, pressure, pH, flow) and an Android-based display module. Connectivity includes USB and Wi-Fi (HTTPS/TLS for manuals/registration only). Cybersecurity controls include signed apps, Google Play Store updates, and no open incoming network ports. Measurement ranges: Conductivity 0-200 mS/cm, Temperature 0-100°C, Pressure -672 to +1551 mmHg, Flow 100-2000 ml/min, pH 0-14.

Indications for Use

Indicated for hemodialysis personnel to test conductivity, temperature, pH, pressure, and flow of dialysate solutions, concentrates, and water during installation and maintenance of hemodialysis delivery systems. Not for daily monitoring prior to treatment.

Regulatory Classification

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.

# SmartHDM-510 System 510(k) Summary

{8}------------------------------------------------

## Performance Testing

The performance testing for the SmartHDM-510 System includes software testing and code reviews, system verification and validation testing, and testing to compliance standards for electrical and electromagnetic safety. Traceability has been documented between the system specification to verification and validation test protocols. Verification and validation test procedures also address the user interface, user manual descriptions, usability, sensor communication and general performance including measuring accuracy.

The design of the device has been verified and validated both through testing and actual experience in international use.

The testing and international experience provided data that demonstrated substantial equivalence to the predicate devices.

## Conclusion

The characteristics of the SmartHDM-510 System are identical to those of the predicate devices in almost all categories. The device has the same intended use as its primary predicate device. Also, it has similar measuring ranges and measuring accuracy as the predicate.

Different to HDM99 and the HDM97, where the display unit, all measuring electronic and pressure sensor are integrated into one housinq, and identical to the 90XL, the SmartHDM-510 System consist of separate devices for the display unit and external connected sensors with integrated measuring electronic. However, SmartHDM-510 System passed all performance tests and hence is as safe as its predicate devices.

The performance of the SmartHDM-510 System is substantially equivalent to that of the predicate devices and do not raise any new questions of safety or effectiveness and performs as well or better than the predicate devices.

Therefore, we conclude that it is substantially equivalent to its cleared predicate devices.
