Design Improvement Side Arm Rejected Due to Burning Process

Abstract

The new material proposed is Polycarbonate Clear(PC clear) which is identified to be able to solve the issue. In addition, the cost of PC clear is much cheaper compared to aluminum alloy plus the manufacturing process is much easier. Since this new side arm is made from PC based material, the flexibility to change the design is excellent as compared to current material of side arm. This new design also eliminates sharp edges on the inner diameter of the side arm which minimize the probability of disconnecting the rubber thread in threading process. The result of producing catheter using new side arm is comparable to current aluminum alloy side arm.
