Efficient body fluid collection device and high-precision body fluid analysis device

Abstract

In the bodily fluid analysis device (71), a bodily fluid extraction unit (23) for storing a bodily fluid excretion-promoting drug and accommodating collected bodily fluid is provided on the lower surface of the bodily fluid collection chip (22). A body fluid discharge promoting drug storage part (31) storing a drug is connected to the drug injection hole (27) provided in the body fluid collection chip. An inspection part (30) for measuring characteristic components in the body fluid is arranged in the body fluid collection chip, and the body fluid extraction part and the inspection part are connected through a body fluid delivery path (29). In addition, a waste bodily fluid storage unit (52) is connected to the outlet of the bodily fluid delivery path. The medicine in the body fluid discharge-promoting medicine storage unit can be supplied to the body fluid extraction unit by operating the medicine supply mechanism (33) composed of a pump, etc., the medicine in the body fluid extraction unit can be discarded to the waste body fluid storage unit, and the medicine in the examination unit after measurement can be discharged. The body fluids are discarded to the waste body fluid storage department.

Description

technical field [0001] The invention relates to a body fluid collection device and a body fluid analysis device. Specifically, it relates to a body fluid collection device and a body fluid collection method for collecting or collecting body fluids (sweat, cell fluid, interstitial fluid of living tissue, etc.) to facilitate extraction of body fluids. Furthermore, the present invention relates to a body fluid analysis device for specifying types and concentrations of components in collected body fluid. Background technique [0002] In recent years, physical and mental stress caused by changes in human diet, lack of exercise, excessive fatigue, etc., as well as bad living habits such as smoking and drinking, have hindered the innate immune function of human beings, thus triggering various diseases. The onset and development of this disease are closely related to living habits, so it is often called lifestyle-related diseases. Lifestyle-related diseases include obesity, hyper...

AI Technical Summary

Problems solved by technology

[0017] In the analysis device of Patent Document 4, since the extracted body fluid is collected in physiological saline, the body fluid and physiological saline are mixed, which greatly affects the measurement accuracy.

Therefore, it is difficult to measure if the concentration of a specific component in a body fluid is low

In addition, depending on the type of specific component to be measured, the components in physiological saline may also become a disturbance factor, resulting in a decrease in measurement accuracy.

In addition, in this analysis device, since it does not have a structure to make physiological saline mixed with body fluids become waste liquid, repeated measurements cannot be performed in the state attached to the body.
