No.
The document explicitly states that the device "does not perform any data processing on the data received" and "Central Station itself does not have the function to perform alarm indication judgment." It also does not mention AI, DNN, or ML. The device functions primarily as a display, recording, and printing system for data processed by other Nihon Kohden devices.
No
The device is a "Central Station" software that displays, records, and prints physiological data from other monitoring devices. It does not perform any data processing for therapeutic purposes, nor does it deliver any therapy. Its function is limited to monitoring and data management.
No
Explanation: The device is a 'Central Station' that displays, records, and prints physiological data from other monitors and devices. It does not perform any data processing or alarm judgment itself, rather it presents data processed and judged by connected Nihon Kohden devices. Its function is to facilitate remote monitoring and data management, not to diagnose.
Yes
The device is explicitly stated as a "software only product that is installed on a Commercial Off The Shelf (COTS) Computer." Its functions are all software-based, primarily focusing on displaying, recording, and managing data from other Nihon Kohden devices. There is no indication of integrated hardware or image processing, AI, or other functionalities that would typically categorize it as a hardware device.
No.
The device displays and manages physiological data from other medical devices, but does not perform tests on specimens derived from the human body.

Dear Arthur Webb:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

(https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

Summary of Nonclinical/Bench Studies
Software
The software documentation was prepared following the FDA's "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" (released June 14, 2023), specifically for an Enhanced Documentation Level. The rationale for choosing this documentation level is detailed in the Documentation Level document.
Verification testing was conducted at the system integration level to confirm that the device software fulfills its requirements and that safety and

security risk mitigations, where applicable, were effective. Additionally, system-level testing was carried out to show that the software addresses user needs. All unit, integration, and system-level tests successfully met the test protocols.
Cybersecurity information has been provided in line with the FDA's "Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions" guidance document, dated September 27, 2023.
The CENTRAL STATION has been designed and verified through a risk analysis that considers the risks associated with interoperability, the anticipated users, reasonably foreseeable misuse, and reasonably foreseeable combinations of events that can result in a hazardous situation. Our Interoperability-related risk management activities are included in Cybersecurity Risk Management activities.
Conclusion:
The results of the substantial equivalence assessment, taken together with non-clinical bench testing, software verification, and validation demonstrate that the Central station does not raise concerns regarding its safety and effectiveness compared to its predicate device and operates in accordance with claimed indications for use.
