Nox Single Patient Use WristOx Straps (pack 100)

The straps are made from medical grade Tyvek (a registered trademark of Dupont). They are amazingly strong but can only be used once, as they have to be destroyed to be removed.  This also makes them fully compatible the the Nox "Chain of Custody" function, which ensures that the patient to be tested is the same person that wears the system overnight.
