Blood analyte level measurement device

A device for non-invasive measurement of at least one blood analyte level in a user, the device comprising:

• a light arrangement configured to emit a light beam with a first wavelength, the light arrangement adapted to be arranged to emit the light beam towards a body part of the user;
• a filtering unit adapted to be arranged to receive the light beam passed through the body part of the user, the filtering unit comprising a polarized filter configured to be displaced between a base position and a target position, wherein the filtering unit is configured to block the light beam received directly from the light arrangement at the base position thereof and to block the light beam received after passing through the body part of the user at the target position thereof;
• a measuring arrangement configured to measure an angle of the polarized filter at the target position with respect to the base position thereof;
• a sensor arranged to receive the light beam passed through the polarized filter, the sensor configured to generate a block signal in response to blockage of the light beam to be received thereat;
• and
• a control unit in signal communication with the measuring arrangement to receive value of the measured angle of the polarized filter at the target position with respect to the base position thereof, and in signal communication with the sensor to receive the block signal indicative of the blockage of the light beam thereat,
• wherein the control unit is configured to determine the at least one blood analyte level in the said body part of the user based on a value of the measured angle of the polarized filter at the target position thereof in response to receipt of the block signal;
• wherein the filtering unit further comprises a motor arrangement configured to displace the polarized filter between the base position and the target position thereof;
• wherein the motor arrangement is configured to displace the polarized filter by performing at least one of an angular displacement or a linear displacement of the polarized filter;
• and
• wherein the polarized filter is displaced by an angular displacement in a range of 0 degree to 90 degrees and/or a linear displacement in the range of 0 millimeters to 50 millimeters at the target position.

• and
• wherein the control unit is configured to determine the at least one blood analyte level in the said body part of the user as normal when the value of the measured angle is about 52.76 degrees in response to the receipt of the block signal.
