Embodiment

[0128] Hereinafter, examples of the present invention will be described, but the present invention is not limited to the following examples.

[0129] In non-invasive lipid measurement, even if the same person is measured, there are places where the change in lipid concentration can be measured and places where it cannot be measured.

[0130] For example, the results of the fat loading test showed that even on an individual level measurements can be made in the veins of the internal forearm, while fluctuations in lipid concentration cannot be measured on the wrist. ( Figure 9 )

[0131] In addition, in the measurement results of the triceps brachii with many capillaries, there were also subjects who could confirm changes in lipid concentration and subjects who could not measure changes in lipid concentration. That is, there are differences among individuals depending on the location, and further, there are individual differences.

[0132] The reason for these differences is...

Abstract

The invention provides a device and a method that enable identification of a suitable site for lipid measurement. This device has: an irradiation unit for irradiating a predetermined site on a livingbody with light directed from the outside to the inside of the living body at a predetermined light intensity; a light intensity detection unit which is either spaced apart by a predetermined distanceor continuous with the light irradiation position used by the irradiation unit, and detects the intensity of light released from the living body; and a control unit for calculating an in vivo staticparameter on the basis of the light intensity detected by the light intensity detection unit, calculating a dynamic parameter which is an index of blood movement on the basis of a change in the staticparameter over time, and determining a site on the living body which is suitable for lipid measurement on the basis of the static parameter and the dynamic parameter.

Description

technical field [0001] The present invention relates to lipid measuring devices and methods thereof. Background technique [0002] Postprandial hyperlipidemia has attracted attention as a risk factor for arteriosclerosis. Reported that if the concentration of neutral fat in the non-fasting period is increased, the risk of incident coronary artery disease is increased. [0003] The diagnosis of postprandial hyperlipidemia requires observation of changes in blood lipid concentration 6 to 8 hours after a meal. That is, in order to measure the state of hyperlipidemia after a meal, it is necessary to restrain the subject for 6 to 8 hours and to collect blood several times. Therefore, the diagnosis of postprandial hyperlipidemia is beyond the scope of clinical research, and it is unrealistic to implement the diagnosis of postprandial hyperlipidemia in the clinical field. [0004] Patent Document 1 discloses a method for solving such a problem. According to the method of Patent...
