Description:

① Smooth inner and outer surfaces: Reduces overall friction

The high-quality PVC catheter series clearly indicates that both the inner and outer surfaces have been smoothed. This treatment directly reduces the friction between the catheter and the urethral mucosa during insertion and removal, and polishes the edge of the drainage side hole to avoid the hole edge becoming an additional source of friction or cutting.

② Catheter head shape: Switch from “rounded” to “through”

The head end design of the PVC catheter is usually a round head, closed structure, and is combined with staggered arranged side drainage holes (staggered eyelets). The design logic of this combination is twofold: The rounded closed head end provides a smooth guiding surface during insertion, making it less likely to “stick” to the mucosa; The staggered side holes maintain the structural strength of the head end while completing the drainage, avoiding weakening the smooth contour of the head end for the purpose of opening the hole. “A gentle, rounded head end helps smooth insertion.” “The unique smooth head end treatment” is less likely to damage the mucosa and reduces the catheter insertion resistance.
