ABSTRACT:
A nasal pack syringe is provided that includes a barrel, a plunger, an expandable, absorbent packing material, and a suture for retrieval of the packing material. The barrel is substantially rectangular in cross-section. The dimensions of the barrel and packing material are influenced by the dimensions of the human nasal cavity. The barrel and packing material are of sufficient length to allow penetration as far as the posterior wall of the nasopharynx. The barrel has ribs projecting from an interior wall thereof to facilitate movement of the packing material and a notch for holding the suture to avoid any obstruction during the movement of the packing material relative to the barrel. The plunger has a split end to assure a tight fit between the plunger and the barrel. In using the nasal pack syringe, the plunger is moved to push the packing material from the barrel into the patient's nasal cavity. The packing material expands upon contact with blood. The packing material absorbs the blood to prevent aspiration of the blood by the patient. Once expanded, the packing material applies hemostatic pressure to ruptured vessels to arrest the flow of blood. Retrieval of the packing material is accomplished by the suture attached to the packing material.
