Non-invasive medical monitoring device for blood analyte measurements

A system for measuring physiological parameters from a tissue site of a patient, the system comprising:

• a plurality of noninvasive sensors configured to obtain physiological data associated with a patient;
• a tissue site attachment component;
• and
• one or more sensor heads comprising:
• a frame configured to support at least a portion of each of the plurality of noninvasive sensors;
• and
• an interlocking component configured to mate with the tissue site attachment component so as to limit movement of the interlocking component with respect to the tissue site attachment component, wherein the tissue site attachment component is configured to couple to a tissue site of the patient, the interlocking component comprising:
• an opening configured to allow at least one of the plurality of noninvasive sensors to obtain physiological data associated with the patient at the tissue site;
• and
• a raised structure configured to be received into a recess of the tissue site attachment component at least partially formed by one or more raised walls of the tissue site attachment component.
