Abstract

A nasal flushing catheter, made of silicone or other soft and elastic material, can be operated by the user himself or herself. The catheter comprises a closed end and an open end on the opposite side. There are multiple side-holes near the closed end. This catheter, when adapted to a connector and further connected to a syringe, can eject multiple strong thin spouts within the nasal cavity and nasopharynx for cleansing mucus and crust. The catheter may contain at least one stylet to improve its controllability. By a given injection rate of 10 cc/sec using a syringe, the average vertical height of spouts can be predicted by the total area of side-holes, the catheter is therefore classified as following: 1. a low pressure catheter, having 3.367 mm2~4.123 mm2 of total areas of side-holes to eject 30 to 45 cm spouts; 2. a medium pressure catheter, having 2.381 mm2~3.367 mm2 of total area of side-holes to eject 45 to 90 cm spouts and 3. a high pressure catheter, having less than 2.381 mm2 of total area of side-holes to eject longer than 90 cm spouts.
