The Life Scope® CSM-1901 Bedside Monitoring Systems are systems which continuously monitors physiological information of a patient and is used in an operation room, a recovery room, general wards, ICU, CCU, HCU, NICU and an emergency room. These systems are placed near the patient and is intended to display patient's vital signs. These systems can also be connected to other external patient monitoring devices. In addition these systems can communicate patient's data to a central monitoring station via network to monitor multiple patients. The input unit is common to NK parent devices that require both a core unit and input unit. NK manufactures the input units with three (3) SpO2 options. The Life Scope® CSM-1901 Bedside Monitoring Systems have interchangeable input units that contains the MULTI socket ports. For larger monitoring systems is data acquisition unit is required to transmit data from the input unit to the core unit. The bedside monitoring systems require both a core unit and an input unit The input unit interprets the electrical impulses from the patient's body and transfers this data into the core unit. The core unit calculates the electrical impulses. Each monitor has a color display and is intended for one patient. The intended populations are all patient populations under the care of health professionals.
The provided text is a 510(k) summary for the Nihon Kohden Life Scope PT BSM-1700 Series, Data Acquisition Unit, LIFE SCOPE BSM 6000 SERIES BEDSIDE MONITORING SYSTEM, and Nihon Kohden CSM-1901 BEDSIDE MONITORING SYSTEM. It describes software modifications to enable compatibility with the Smart Cable NMT Module and Accessories, and updates to the stated Indications for Use.
The document does not contain information about an AI/algorithm-only study, a multi-reader multi-case (MRMC) comparative effectiveness study, or details on ground truth establishment for a training set. The device in question is a physiological monitor, and the software modifications are specifically related to integrating with a neuromuscular transmission (NMT) module and updating intended use statements, not for an AI/CADe (Computer-Aided Diagnosis/Detection) algorithm that would typically require such studies.
Therefore, many of the requested criteria related to AI/algorithm performance and clinical validation studies are not applicable to the information provided in this document.
Here's a breakdown of the available information:
1. Table of Acceptance Criteria and Reported Device Performance
The document states that the software modifications do not change the safety, performance of the predicate devices. It refers to integration testing, not a de novo performance study with specific quantifiable acceptance criteria for a new AI algorithm.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Device functions as intended with new software. | Confirmed operation of the device when the Smart Cable NMT software was integrated into the system. Results confirmed the device performed within specifications. |
| Software modifications do not raise different questions of safety and effectiveness. | Software input units modifications and labeling modification do not raise different questions of safety and effectiveness. |
| Compliance with relevant electrical safety and EMC standards. | Complies with ANSI AAMI ES60601-1 / IEC 60601-1 for safety and IEC 60601-1-2 for EMC. |
2. Sample size used for the test set and the data provenance:
- Sample Size: Not specified in terms of patient data. The testing mentioned is "software unit testing, integration level testing, and system-level testing" and a "system test... based on the software requirements specification." This suggests internal product testing rather than a separate clinical test set of patient data.
- Data Provenance: Not applicable, as no external clinical data test set is described. The focus is on the integration and functional testing of the software within the device system.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. The ground truth, in this context, would be the proper functioning and integration of the software and hardware, verified through engineering and system testing, not through expert reading of medical images or data.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable. This is typically used in clinical studies for establishing ground truth for AI algorithms, which is not the subject of this 510(k).
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No. The document explicitly states: "No clinical tests have been submitted, referenced or relied on in this premarket notification submission for a determination of substantial equivalence." This device is not an AI-assisted diagnostic or therapeutic tool; it's a physiological monitor with updated software for compatibility.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- No. This is not an AI algorithm requiring standalone performance evaluation. The "software modification" refers to updates enabling the NMT module to work with the monitoring system.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For the software and system functionality: The ground truth is the predefined technical specifications and expected behavior of the device and its integrated components. This is verified through "software unit testing, integration level testing, and system-level testing."
8. The sample size for the training set:
- Not applicable. There's no machine learning model or AI algorithm described that would require a "training set."
9. How the ground truth for the training set was established:
- Not applicable for the same reason as above.
