The Surflo Winged Infusion Set is indicated for venipuncture and intravenous administration of fluids for up to 24 hours using compatible/appropriate disposable infusion devices for medical purposes. It may be used for any patient population with consideration given to patient size.
The Surflo Winged Infusion Set consists of a protector, needle, wing, tubing, connector, and connector cap. The connector is 6% female Luer. It is primarily made from medical grade PVC (the whole device uses TOTM as plasticizer instead of DEHP) and medical grade stainless steel. The Surflo Winged Infusion Set is operated manually. The device is intended to be used by trained healthcare professionals in a healthcare facility. The Surflo Winged Infusion Set is available in different gauge sizes and tubing lengths. The Surflo Winged Infusion Set is a disposable device intended for single use only. The device is packaged and sterilized by ethylene oxide gas.
This document is a 510(k) Premarket Notification for the Surflo Winged Infusion Set, seeking substantial equivalence to a legally marketed predicate device. As such, it describes performance testing conducted to demonstrate product safety and effectiveness, rather than a study proving a device meets acceptance criteria for an AI/ML product. Therefore, several points in your requested output, such as those related to AI/ML specific criteria (e.g., sample size for training set, number of experts for ground truth establishment, MRMC study, standalone performance) are not applicable to this type of medical device submission.
However, I can extract and present the relevant information regarding acceptance criteria and performance testing for this traditional medical device:
