The catheter has a closed end and an open end on the opposite side. There are multiple 5 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 10cc/sec using a syringe, the average vertical height of spouts can be 10 predicted by the total area of side-holes, the catheter is therefore classified as following: 1. a low pressure catheter, having 3.367mm 2 4.123mm 2 of total areas of side-holes to eject 30 to 45cm spouts 2. a medium pressure catheter, having 2.381mm 2 ~3.367mm 2 of total area of side-holes to eject 45 to 90cm spouts and 3. a high pressure catheter, having less than 2.381mm 2 of total area 15 of side-holes to eject longer than 90cm spouts.16/18 F1 GI FIG.16
