I noticed in the description that it is disposable. Is it only a single use item or can it be used multiple times? If it is a multiuse product, how can it be disinfected in between patients?

No, this item is not designed to be re-used. It is sold sterile and designed to be used for one patient and then disposed of. A similar item is available that can be reused. It is called the DuraHand Non-Sterile Surgical Hand Immobilizer. The cleaning and sterilization instructions for that item are listed on the item detail page on our site.
