    • A medical catheter assembly including a multi-piece connector. In one embodiment, the medical catheter assembly is a PEG implanting assembly comprising a tubular dilator and a silicone feeding tube having an internal bolster at its rear end. The assembly also comprises a multi-piece connector comprising an inner ring, a fitting and an outer ring. The inner ring has an outer diameter greater than the inner diameter of the feeding tube and is coaxially disposed within the feeding tube by a friction-fit. The fitting comprises a front portion, an intermediate portion and a rear portion, the intermediate portion including a shoulder having an outer diameter greater than the inner diameter of the feeding tube. The front portion of the fitting is inserted through the rear end of the dilator and is secured to the dilator by a plurality of barbs. The shoulder and the rear portion of the fitting are inserted into the feeding tube through its rear end, with the rear portion of the fitting being inserted into the inner ring and secured thereto by mating threads. The outer ring is inserted over the feeding tube and is positioned between the shoulder and the inner ring, the outer ring being sized to securely retain the feeding tube between the outer ring and the inner ring and between the outer ring and the shoulder.
    • 一种医疗导管组件,包括多片连接器。 在一个实施例中,医疗导管组件是PEG植入组件,其包括管状扩张器和在其后端具有内部枕垫的硅胶进料管。 组件还包括多片连接器,其包括内环,配件和外环。 内圈的外径大于进料管的内径,并通过摩擦配合同轴地设置在进料管内。 该配件包括前部,中间部分和后部,中间部分包括具有大于供给管内径的外径的肩部。 配件的前部插入穿过扩张器的后端,并通过多个倒钩固定到扩张器。 配件的肩部和后部通过其后端插入进料管中,配件的后部插入内圈并通过配合螺纹固定在其上。 外环被插入进料管上并且位于肩部和内圈之间,外圈的尺寸设计成将进料管牢固地保持在外圈和内圈之间以及在外圈和肩部之间。
