This battery is shipped only to customers who request a replacement battery for a particular device or to replace a competitor's replacement battery. The biomedical equipment technician therefore knows the intended use is as a replacement battery.
Rechargeable Battery Part Number MS61010
The provided text is a 510(k) premarket notification approval letter for a replacement battery, the Alexander Manufacturing Company Rechargeable Battery Part Number MS61010. This document addresses regulatory approval and substantial equivalence to a predicate device, rather than the performance of a novel medical device or AI system against specific acceptance criteria in a clinical study.
Therefore, the information required to answer your request (acceptance criteria, study details, sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC study results, or standalone performance for an AI/medical device) is not present in the provided text.
The document states: "We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976...". This signifies a regulatory determination based on comparison to an existing device, not a performance study against predefined acceptance criteria as would be typical for a new diagnostic or AI-based device.
§ 880.2910 Clinical electronic thermometer.
(a)
Identification. A clinical electronic thermometer is a device used to measure the body temperature of a patient by means of a transducer coupled with an electronic signal amplification, conditioning, and display unit. The transducer may be in a detachable probe with or without a disposable cover.(b)
Classification. Class II (performance standards). The device is exempt from the premarket notification procedures in part 807, subpart E of this chapter, subject to the limitations in § 880.9 and the following conditions for exemption:(1) Device is not a clinical thermometer with telethermographic functions;
(2) Device is not a clinical thermometer with continuous temperature measurement functions; and
(3) Appropriate analysis and testing (such as that outlined in the currently FDA-recognized editions, as appropriate, of ISO 80601-2-56, “Medical electrical equipment—Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement,” or ASTM E1965, “Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature,” or ASTM E1112, “Standard Specification for Electronic Thermometer for Intermittent Determination of Patient Temperature,” or ASTM E1104, “Standard Specification for Clinical Thermometer Probe Covers and Sheaths”) must validate specifications and performance of the device.
