Problems solved by technology

For the above reasons, the method of estimating daily excretion from nocturnal urine has the disadvantage that it is difficult to obtain accurate and reproducible values ​​unless appropriate corrections are made.
[0009] Furthermore, even if the method described in Non-Patent Document 1 is used to estimate the daily urine excretion from nighttime urine corrected by time (converting the urine volume to 8 hours), there are cases where the correction is insufficient.

Embodiment 1

[0094]

[0095] FIG. 2 is a hardware configuration diagram of a daily urine excretion measurement device according to this embodiment. The urine excretion measuring device 100 for one day is a device for measuring the urine volume of excreted urine and the amount of urine components contained in the urine in one urination, and by using this device to measure the last excretion of the day before going to bed The amount of urine components contained in excreted urine, that is, the amount of urine components contained in urine before going to bed, and the amount of urine components contained in urine that is excreted for the first time after waking up (hereinafter referred to as "night urine"), That is, the amount of components in the urine at night, so as to automatically calculate the total amount of the components in the urine excreted in the urine in a day (for example, from the time of the first excretion of urine after waking up). Unit 2 and sensor 3 are composed. The co...

Embodiment 2

[0141]

[0142] FIG. 8 is a block diagram showing the configuration of a daily urinary excretion measurement device 200 that calculates a daily urinary excretion by correcting the amount of urinary sodium at night for 8 hours. The main difference from the above-mentioned daily urine excretion measurement device 100 is that the 8-hour correction unit 712 performs 8-hour correction for the amount of urinary salt in the nighttime, and the 8-hour correction unit 712 is newly provided to calculate the daily urine excretion. unit 713 , excretion time information determination unit 714 , urine component amount storage unit 715 , regression equation storage unit 716 , notification menu display unit 717 , and notification schedule storage unit 718 . In the urine excretion measurement device 200 for one day, the notification menu display unit 717 and the display unit 207 correspond to the “measurement notification unit, which is used to collect spot urine and the urine content calculat...

[0166]

[0167] FIG. 10 is a block diagram showing the configuration of a daily urine excretion measuring device 300 for which a regression equation is prepared for each user. The daily urinary excretion measuring device 300 of the third embodiment accumulates the amount of urinary salt in urine before going to bed for at least three days, the amount of urinary salt in night time corrected for 8 hours, and the sum of these two amounts of urinary salt in urine. The amount of salt excreted in urine corresponding to a day is shown in a graph shown in FIG. 7 , and a regression equation is written for each user based on the least square method. In addition, after writing the regression equation, the urine excretion amount measuring device for one day calculates the urine excretion amount of salt using the written regression equation. The urine excretion measurement device 300 for one day includes: a suggestion storage unit 417, an 8-hour correction unit 712, a daily urine excreti...

Abstract

A daily urinary excretion measurement apparatus and a method thereof, for measuring daily excretion of a urine component highly accurately and easily, are provided. A daily urinary excretion measurement apparatus (100) includes: a urine component calculation unit (411) which measures the amount of the urine component included in before-bedtime urine that is excreted for the last time before bedtime in the day and the amount (salt) of the urine component (salt) included in overnight urine that is excreted for the first time after wake-up on the next day following a sleep; a regression equation storage unit (416) which stores a correlation (a regression equation) between the amount of the before-bedtime urine component and the amount of the overnight urine component and a total amount of the urine component included in daily urine; a daily urinary excretion calculation unit (413) which calculates the total amount of the urine component excreted in the daily urine according to the regression equation stored in the regression equation storage unit (416), using the amount of the before-bedtime urine component (salt) and the amount of the overnight urine component (salt) calculated by the urine component calculation unit (411).

Description

technical field [0001] The present invention relates to a device and method for measuring the amount of urinary components excreted in urine, thereby estimating the total amount of the urine components excreted in a day. Background technique [0002] Urinalysis is a non-invasive inspection method with a simple sampling method, and has been widely used for a long time because there is no invasion such as pain during urine collection. Urine contains various components such as salt, sugar, and protein whose concentration varies according to the living conditions and health status of the subject, and if these components can be easily measured at home, it will be useful for health management. For example, excessive intake of salt is considered a cause of high blood pressure or gastric cancer, and although intake management is desired, it is very troublesome and labor-intensive to measure and calculate the total amount of salt in food intake. Therefore, a method of managing the a...
