1. A method of forming a molded pulse oximeter sensor apparatus utilizing an overmolding step, comprising:
- supplying a preform first section having an interior surface and an exterior surface;
securing oximeter sensing components in a fixed configuration to said interior surface of said preform first section so that the position of said sensing components will be maintained during overmolding; and
utilizing injection molding to overmold a second section which is bonded to said preform first section such that said sensing components are enclosed between said preform first section and said overmolded second section, and wherein the bond between said preform first section and said overmolded second section at their peripheries comprises a mechanical bond of overlapping elements.
