Abstract

A cholesterol measurement device includes a measuring instrument body; and a light-intensity check member mounted on and integrated with the measuring instrument body. The light intensity check member reflects light emitted from a light-emitting unit, allowing detecting abnormal light intensity and accurate assessing light intensity change, which prevents a measurement value change due to the change in light intensity and improves reliability of the measurement value. The device keeps a measurement unit clean all the time since the measurement unit can be easily cleaned by separating a strip fixation unit, when a specimen flows into the strip fixation unit in which a measurement strip is inserted.

Core Innovation

A cholesterol measurement device is provided with a measuring instrument body that includes a measurement unit where a measurement strip is positioned and a light-emitting unit that emits light to the measurement unit. The device detects the intensity of light reflecting with a photo diode after emitting the light to the measurement strip to measure the quantity of cholesterol, and includes a light-intensity check member that is mounted on and integrally provided with the measuring instrument body to reflect emitted light and check whether the intensity of light is abnormal.

The measuring instrument body includes a body housing member where the measurement unit is provided at one side and the light-emitting unit is provided therein. An opening/closing member opens and closes the measurement unit, and the light-intensity check member is positioned on a lower surface of the opening/closing member. A measurement window member through which the light emitted from the light-emitting unit passes is positioned in the measurement unit, and the light-intensity check member is elastically supported by a spring member in a state where the opening/closing member is closed, and is positioned in close contact with the measurement window member.

A strip inlet is positioned at one side of the opening/closing member so that the measurement strip can be inserted between the light-intensity check member and the measurement window member in the state where the opening/closing member is closed. The light-intensity check member has a block shape having a flat lower surface and an inclined surface positioned at a front end side toward the strip inlet to guide insertion of the measurement strip.

The device includes a real-time clock and a light-intensity abnormality checking unit, and when power is turned on, the device checks for a date change and operates the light-emitting unit to emit light for a light-intensity check, thereby determining whether the light-emitting unit is abnormal based on light reflected by the light-intensity check member. The device can output the cholesterol measurement values by using a detachably coupled portable printer body that is electrically connected and includes a rechargeable battery.

Claims Coverage

The claim coverage includes one independent claim for a cholesterol measurement device with an integrated light-intensity check member and photodiode-based reflected light intensity detection, with structural arrangement including an opening/closing member, a measurement window member, elastic support, and a strip inlet guide. Additional dependent claims further specify RTC-tied checking, a detachable printer with rechargeable battery, and strip fixation geometry and locking.

The inventive features center on photodiode-based reflected light intensity measurement for cholesterol, integration of a light-intensity check member to determine abnormal light intensity, and the mechanical arrangement that places the check member in close contact with a measurement window during operation while guiding strip insertion using a block-shaped check member with an inclined surface.
