摘要：
A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.導尿管可包括一導管軸及一連接器，該連接器與該導管軸的近端耦合。該連接器可具有第一支路及第二支路，該第一支路結束於一流體出口，該流體出口經配置以允許尿液從該導尿管流出，該第二支路具有一孔洞且結束於一膨脹入口，該膨脹入口用於將膨脹流體導入至該導尿管中。該導管可進一步包括一主要管腔、一膨脹管腔、一留置球囊、及一前導球囊，該留置球囊在靠近一流體入口且在一遠側填注孔上方處安裝至該導管軸，該前導球囊在該孔洞上方經安裝至該連接器的該第二支路上。該前導球囊在一膨脹壓力下膨脹，該膨脹壓力高於該留置球囊的膨脹壓力並低於一預設壓力閾值。
