The SNAP device clicks directly onto a conventional surgical mask. It creates a hole in the mask through which an endoscope can easily pass. The patient then wears the mask and aligns the internal aspect with their nose, the clinician can then endoscope the patient. On withdrawal of the endoscope, there is a one-way valve that closes the hole. Any coughs, splutters or sneezes during the procedure are caught within the mask which is disposed of at the end. We envisage this device will reduce the risk for clinicians and help us get back nasendoscoping patients and delivering high quality healthcare.
