ABSTRACT:
An apparatus is disclosed for measuring a blood constituent. In a preferred embodiment, the apparatus includes a semipermeable membrane for defining a volume with a flexible membrane disposed on one end and with a light source disposed on an opposite end. The flexible membrane flexes to become the moving mirror in an FTIR system.
