Med-link Disposable Blood Pressure Cuff has the same intended use, basic construction and technology specification as the predicate device. They are wrapped around the patient's arm or thigh and secured by a hook and loop fastener commonly called Velcro.

We extend the size to satisfy some special patients such as different neonatal size. Based on the performance testing in this submission, the slight difference on the range of these blood pressure cuffs does not raise any safety or effectiveness issue.

#### 10. Comparison of Performance with Predicate Device

Performance testing was performed on the subject device and results were compared with predicate device. Tests were conducted following applicable procedures outlined in the FDA recognized consensus standard of AAMI/ANSI/ISO81060-1:2007/(R)2013, and results met all relevant requirements in the test standard.
