Abstract
A method for simultaneously isolating the flow of blood in a nasal cavity and withdrawing the blood from the nasal cavity is disclosed. The method comprises the steps of inserting a catheter into the nasal cavity. The catheter is composed of a tube and a duct and a forward end capable of being enlarged to form a balloon. Once the catheter is positioned in the nasal passage, air is pumped into the catheter through the tube to inflate the balloon. The inflated balloon forms a seal within the nasal cavity that prevents the flow of blood beyond the seal. Simultaneously, blood is drawn into the catheter by applying a suction force to the duct. Suction may be accomplished by attaching a vacuum at the opposite end of the catheter and connecting it to the duct. The blood is drawn into the duct through a plurality of holes that connect the periphery of the catheter with the duct. The blood thus drawn into the duct is removed from the nasal cavity and disposed away from it.
