Assignee: CARDIACSENSE LTD.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 6:
7. A measuring device, comprising:
at least one biological sensor; and
a displacement sensor assembly, configured to increase accuracy of operation of the at least one biological sensor, the at least one biological sensor being configured for optically measuring at least one biological parameter of a user
wherein the displacement sensor assembly is configured for use in measuring a biological parameter at the skin of a user, the displacement sensor assembly comprising:
a skin contact surface facing towards an exterior of the assembly and configured for contacting the skin of a user, and movable along a central axis of the assembly in response to pressure change at the skin;
a sensing unit disposed within an interior of the assembly and having an optical axis lying in a plane perpendicular to the central axis of the assembly; the sensing unit comprises a light source configured to emit light along the optical axis and a light detector facing towards the light source and configured to detect light emitted by the light source directly towards the detector; and
a light blocking member operative to change the amount of light reaching the detector directly from the light source in consequence with displacement of the contact surface, whereby the light received by the light detector being indicative of the displacement of the contact surface.
