The BioHoop Collection Bags are ideal for a variety of uses, including collecting emesis, urine, or other bodily fluids, evidence collection, or holding patient personal belongings (cell phones, jewelry, wallets, for example). The semi-rigid hoop at the top of the bag keeps the large mouth open wide to provide a large area for expelled fluids to find a way into the bag (instead of all over the responder). After the bag has been filled, the top quickly and securely zips shut by pulling a strap. Each bag includes a hook so it can be attached to a patient, on an ambulance cot, hospital bed, or wheel chair. The leak-proof, transparent material and the included volume measurements on the bag make it easy for health care professionals to inspect the sample as needed. Latex-free.
