In addition, the lamp may also help muscle spasms, minor sprains and strains.

Device Description

The WSTM Far-Infrared Therapy Unit, Model: KP-B210, is an infrared heating system which delivers 3~25 um Far-infrared energy through Far Infrared (FIR) radiation plate. The device is a non-invasive physiology therapy device and emits topical heat to the human forearm and upper arm for therapeutic applications without direct contact. The model, KP-B210 is a single object without additional assembly which contains an emitter, a user control panel, a power switch and safety distance reminder.

AI/ML Overview

This document pertains to a 510(k) premarket notification for a medical device (WSTM Far-Infrared Therapy Unit, Model: KP-B210) and does not describe a study involving an algorithm's performance, human readers, or ground truth establishment in the context of AI. Therefore, I cannot extract the requested information.

The document primarily focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing (electrical safety, EMC, spectrum, functional certification, usability, and temperature safety tests) and comparing technical specifications. No clinical test data was used to support the decision of substantial equivalence, and there is no mention of an algorithm or AI.

Dear Chih-wen Tsai:

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 (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. 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.
