Abstract
A method of molding the main body of a Y-adapter that has a straight passageway extending from one extremity to the other and an arcuate passageway that is generated along the arc of a circle. Core pins for the straight and arcuate passageways are placed in a mold such that they merges together to form a single, smooth lumen in the Y-adapter. The arcuate core pin can be withdrawn from the finished Y-adapter as a result of its circular arc.
Claims3
A method of molding the main body for a Y-adapter that has a straight passageway extending from one extremity to the other and an arcuate branch passageway that smoothly merges into the straight passageway including the step of:
- (a) providing a mold for the main body that includes means for supporting a straight core pin and an arcuate core pin, said straight and arcuate core pins each include corresponding mold shut off surfaces that interface with each other such that a single, smooth passageway is formed in the main body and such that after the main body has been molded the proximal and distal ends of the straight and arcuate core pins are accessible from outside of the molded main body,
- (b) placing the straight and arcuate core pins in the mold prior to injecting the material, from which the main body is to be formed, into the mold;
- (c) injecting the material from which the main body is to be formed into the mold;
- and
- (d) exerting force on the straight and arcuate cores causing them to slide out of the molded main body.
