A collection of sterile devices designed to perform an intraosseous (IO) infusion (i.e., an infusion directly into the bone's medullary cavity for the purpose of administering emergency medications and other fluids). It typically consists of a needle (possibly of a special design), an inserting handle, a scalpel, an infusion set, swabs and sutures. This device is used as an alternate to the preferred intravenous (IV) route when this cannot be established in a timely manner, typically during cardiac arrest, patients with respiratory failure or in shock, and when peripheral IV infusion is very difficult. This is a single-use device.
