Apparatus and method for measuring biologic parameters
View Patent ↗Support structures for positioning sensors on a physiologic tunnel for measuring physical, chemical and biological parameters of the body and to produce an action according to the measured value of the parameters. The support structure includes a sensor fitted on the support structures using a special geometry for acquiring continuous and undisturbed data on the physiology of the body. Signals are transmitted to a remote station by wireless transmission such as by electromagnetic waves, radio waves, infrared, sound and the like or by being reported locally by audio or visual transmission. The physical and chemical parameters include brain function, metabolic function, hydrodynamic function, hydration status, levels of chemical compounds in the blood, and the like. The support structure includes patches, clips, eyeglasses, head mounted gear and the like, containing passive or active sensors positioned at the end of the tunnel with sensing systems positioned on and accessing a physiologic tunnel.
1. A thermal sensing support structure comprising:
a body for placement on a skin surface, said body including an adhesive layer for securing the body on the skin surface, said body being connected to an arm movable towards a brain tunnel area and a measuring portion located at a free end of the arm and configured to be placed at the brain tunnel area and biased against the brain tunnel area by the arm, said measuring portion having a thermally insulating surface,
said thermally insulating surface having at least one thermal sensor exposed to directly contact and receive thermal energy from said skin surface, the movable arm being configured to ensure the direct biased contact of the at least one thermal sensor with the skin surface at the brain tunnel area,
the measuring portion being free of adhesive, and
said at least one thermal sensor being only partially surrounded by said thermally insulating surface so that said at least one thermal sensor is located exposed from said thermally insulating surface for direct contact of the at least one thermal sensor with the skin surface at the brain tunnel area.
