A collapsible nasal ejecting catheter, made of thermoplastic elastomer or other soft and elastic materials, can be operated by the patient to insert into nasal cavity and nasopharynx. The catheter comprises a catheter body and a connector, having a flat closed end and an open end on the opposite side. There are multiple side-holes near the closed end. This catheter, when connected to a syringe, can eject multiple strong thin spouts within the nasal cavity or nasopharynx for cleansing mucus and crust. The flat close end and the collapsibility facilitate better navigation of the catheter through the slit like space of nasal cavity to reach the deeper and narrower region to improve the flushing efficacy and also can avoid incidental insertion into sinus.一種以熱塑性彈性體或其他柔軟具彈性之材質製成之可塌陷鼻腔噴射導管,可供病人自行操作置入鼻腔及鼻咽。該導管包括一扁平狀封閉末端及一相反於該封閉末端之開放端。該導管於接近該封閉末端處開設複數邊孔,如配合一銜接器及一注射筒可在鼻腔及鼻咽噴出多重強勁細長水柱以清洗粘液及結痂。因為導管之扁平狀封閉末端及可塌陷性,使較大外徑之導管可順行於隙縫狀空間,抵達狹窄之深處產生較佳的沖洗效果,也可以避免誤入鼻竇。61‧‧‧導管本體611‧‧‧扁平狀封閉末端613‧‧‧邊孔
