Description

本発明は、尿(小便)と便(大便)を分別した重量測定方法とその装置に関するものである。 The present invention relates to a weight measuring method for separating urine (urine) and stool (stool) and an apparatus therefor.

尿量の測定方法は、蓄尿瓶やプラスチックバックに集めた尿をメスシリンダーや重量計等で測定する方法、自動尿量測定器で計測する方法、便器の内部に取り付け外しできる容器で測定する方法が知られている。他に、特許文献1では、蓄尿容器に600〜800nmに吸収を持つ物質を添加しておき、蓄尿後にその物質の濃度を測定する方法、これと同様に特許文献2では、酵素基質を含有させ、蓄尿後にこの濃度を計る方法、特許文献3では、直接便器内に尿捕集のボウルを備えて、排泄前後のボウル内の水位に基づき排泄物量を算出する方法が知られている。近年、尿と大便を区別してその量を測定することが望まれているが、そのような要望に対応できるものは、先行技術では、見当たらない。 The method of measuring urine volume is a method of measuring urine collected in a urine storage bottle or plastic bag with a graduated cylinder or weighing scale, a method of measuring with an automatic urine volume measuring device, a method of measuring with a container that can be attached to and detached from the toilet. It has been known. In addition, in Patent Document 1, a substance having absorption at 600 to 800 nm is added to a urine storage container, and the concentration of the substance is measured after urine storage. Similarly, in Patent Document 2, an enzyme substrate is contained. A method for measuring this concentration after storing urine, Patent Document 3 discloses a method in which a bowl for collecting urine is provided directly in the toilet and the amount of excreta is calculated based on the water level in the bowl before and after excretion. In recent years, it has been desired to distinguish between urine and stool and measure the amount thereof, but there is no prior art that can meet such a demand.

図1は、本発明にかかる尿と便を分別した重量測定方法の測定フローの一実施態様を示す図である。図9に示すように尿と便が混在している場合に分別して測定することが一番難しい。先ず図9において、オムツや水分吸収シート、採便・採尿容器等の尿便受け体210と尿220と便230が混在状態を示す。
図2は、本発明にかかる尿と便を分別した重量測定方法及びその装置の便部水分率r決定手段の一実施態様を示す図である。
本願では、便の状態(便秘などかなり固め、普通、下痢など水っぽい)を把握する工程を取る。一般に便は、2−Cに示すように、便状態により、水分の量が、便秘などかなり固めで70%、普通で80%、下痢状態で90%と言われる。これらの事情をまず説明する。オムツや水分吸収シート、採便・採尿容器等の尿便受け体210に尿220と便230が混在していたとする。このような状態を医者や看護人が見れば、便の状態を見て、おおよその水分率を判断は容易である。2−Bにおいては、便状態の把握を人的に行った場合の便部水分率r決定手段を示す。医者や看護人など人的に便部を見れば、固い便か、普通の便か、下痢状の便か、或いは、それらの中間の状態か、一目瞭然であるから、例えば、下痢状態なら、それに対応する便状態選択ボタン240を押す。押された便状態選択ボタン240の出力により水分率選択テーブル250のなかから対応する便部水分率rが決定され出力され、後の計算に用いられる。例えば、下痢状態に対応するボタンが押され、便部水分率rは0.9として決定される。
FIG. 1 is a diagram showing an embodiment of a measurement flow of a weight measurement method for separating urine and feces according to the present invention. As shown in FIG. 9, it is most difficult to measure separately when urine and feces are mixed. First, in FIG. 9, a urine / stool receiving body 210 such as a diaper, a water absorbing sheet, a stool collection / urine collection container, the urine 220 and a stool 230 are shown in a mixed state.
FIG. 2 is a diagram showing an embodiment of a weight measuring method for separating urine and stool according to the present invention and a stool moisture content r determining means of the apparatus.
In the present application, a step of grasping the state of stool (constipation such as constipation is fairly solid, usually watery such as diarrhea) is taken. In general, as shown in 2-C, stool is said to have a moisture content of 70% for constipation, 80% for normal, and 90% for diarrhea, depending on the stool condition. First, these circumstances will be explained. It is assumed that the urine 220 and the stool 230 are mixed in the urine / stool receiving body 210 such as a diaper, a moisture absorbing sheet, and a stool / urine collection container. If a doctor or nurse sees such a state, it is easy to determine the approximate moisture content by looking at the state of the stool. In 2-B, the stool part moisture content r determination means at the time of grasping | ascertaining a stool state is shown. If you look at the stool partly, such as a doctor or nurse, it is obvious whether it is a hard stool, a normal stool, a diarrhea-like stool, or an intermediate state between them. The corresponding flight state selection button 240 is pressed. Based on the output of the pressed stool state selection button 240, the corresponding stool moisture content r is determined and output from the moisture content selection table 250, and is used for subsequent calculations. For example, a button corresponding to a diarrhea state is pressed, and the stool moisture content r is determined as 0.9.

2−Aにおいては、機械的な判断の例である。
もっとも容易なのは、便230の画像を撮影することである。
画像等便状態出力(この図ではカメラによる映像)は、便部水分率r決定手段410に入力される。
尿220部と便230部は、便部水分率r決定手段410内の便部特定手段260でパターンマッチングすれば、容易に分別できる。尿220部は、水分だけで構成されているし、固形部を含んだ部分は、便230部と判断すればよい。便230部の映像は、便部水分率r決定手段410内の便状態と水分率対応テーブル270のデータを参照して、便状態が同じか近い状態の便部水分率rを求める。これを行うのが、便状態マッチング手段280である。その結果が出力され、後の計算に使われる。
尚、医者や看護人などが、便状態から適当と思われる便部水分率rの値自体を直接入力することも可能である。
上記の3段階の値でも誤差は少ないが、予め、色々な既知(計測されて)の便部水分率rの便状態を比較のための値として用意することもでき、測定精度を上げることができる。
例えば、便部の全重量200gとして、普通状態と固い又は、下痢状態を入れた水分の量は、160±20g(12%)に過ぎない。従って、3段階でも十分な精度で計算に使えるのである。従って、上記の12%の誤差を許容すれば、便部水分率rを0.8と固定した値に設定して計算することも可能であり、その場合には、便状態の把握を省くこともでき便利である。
2-A is an example of mechanical judgment.
The easiest way is to take an image of the stool 230.
The stool status output (image by the camera in this figure) such as an image is input to the stool moisture content r determining means 410.
The urine 220 parts and the stool 230 parts can be easily separated by pattern matching by the stool part specifying means 260 in the stool part moisture content r determining means 410. 220 parts of urine is composed only of moisture, and the part including the solid part may be determined as 230 parts of stool. The image of the stool 230 part refers to the stool state in the stool part moisture content r determining means 410 and the data in the moisture rate correspondence table 270 to obtain the stool part moisture content r in a state where the stool state is the same or close. This is performed by the fecal state matching means 280. The result is output and used for later calculations.
It is also possible for a doctor, a nurse, or the like to directly input the value of the stool moisture content r, which is considered appropriate from the stool state.
Although there are few errors even with the above three-stage values, various known (measured) stool moisture percentages of the stool moisture content r can be prepared in advance as values for comparison, thereby increasing the measurement accuracy. it can.
For example, assuming that the total weight of the stool is 200 g, the amount of water that is firm and normal or that includes diarrhea is only 160 ± 20 g (12%). Therefore, even three stages can be used for calculation with sufficient accuracy. Therefore, if the above error of 12% is allowed, it is possible to calculate by setting the stool moisture content r to a fixed value of 0.8. It is also convenient.

このように、便状態を把握した後では、便部水分率rが求まるので、これを使い計算を行う。再び、図1に戻る。
次に、尿と便の全体の重量Mを計る。
その後、尿と便の水分重量WH2O又は、便の固形物重量Hを計る。前者では、水分のみを検出する測定が必要であり、図3で説明する。後者では、尿を含む水分の除去を行った後、固形分の重量を計る。この場合は、図7で説明する。いずれの測定も、尿便受け体210の重量は、既知であるため、これを差し引いた正味の重量値であることは当然である。
次に、尿重量Uと便重量MBを算出する。算出に使う式は図1に示される通りである。
計算した結果を出力手段により出力する。
このようにして、尿と便が混在した場合も、両者を分別して各々の重量を求めることができる。
In this way, after grasping the stool state, the stool moisture content r is obtained, and this is used for calculation. Returning again to FIG.
Next, the total weight M of urine and feces is measured.
Thereafter, the moisture weight WH2O of urine and feces or the solid weight H of feces is measured. The former requires measurement for detecting only moisture, and will be described with reference to FIG. In the latter, after removing water including urine, the solid content is weighed. This case will be described with reference to FIG. In any measurement, since the weight of the urine / feces holder 210 is known, it is natural that it is a net weight value obtained by subtracting the weight.
Next, urine weight U and fecal weight MB are calculated. The formula used for the calculation is as shown in FIG.
The calculated result is output by the output means.
In this way, even when urine and feces are mixed, the weights of the urine and stool can be obtained by classification.

図3は、本発明にかかる尿と便を分別した重量測定方法の測定フローの内、水分重量の測定値から尿と便の各量を計算する方法のフローの一実施態様を示す図である。
この測定の長所は、水分を除去することが必要なく、短時間で測定可能なことである。
図1で説明した、便部水分率rの決定と、尿と便の全体重量Mの測定は、同じである。尿と便の水分重量WH2Oの測定を行う。これができれば、尿重量Uと便重量MBを算出する。算出に使う式は図3に示される通り、
尿重量計算U=(WH2O−rM)/(1−r)
便重量計算MB=(M−WH2O)/(1−r)である。
計算結果を出力する。
水分だけの重量WH2Oの測定は、どのように行うのがよいか、その例を図5を使い説明する。図5は、図4の装置の水分重量測定手段の一実施態様を示す図である。
FIG. 3 is a diagram showing an embodiment of a flow of a method for calculating each amount of urine and feces from a measured value of moisture weight in the measurement flow of the weight measuring method for separating urine and feces according to the present invention. .
The advantage of this measurement is that it can be measured in a short time without having to remove moisture.
The determination of the stool moisture content r and the measurement of the total weight M of urine and stool described in FIG. 1 are the same. Measure urine and fecal moisture weight WH2O. If this is possible, the urine weight U and the stool weight MB are calculated. The formula used for the calculation is as shown in FIG.
Urine weight calculation U = (W H2O -rM) / (1-r)
Stool weight calculation M B = (M−W H2O ) / (1−r).
Output the calculation result.
An example of how to measure the weight WH2O with only water is described with reference to FIG. FIG. 5 is a view showing an embodiment of the moisture weight measuring means of the apparatus of FIG.

載置台510の上に、尿便受け体210上に尿220と便230が混在して、存在している。電磁波照射手段520から既知の強度の電磁波が照射され、尿便受け体210、尿220と便230を透過する。尿便受け体210と載置台510と便固体は、電磁波に対して吸収性でないか、有っても水より弱い。電磁波としては、マイクロ波、ミリ波、テラヘルツ波が水に吸収される。図の真ん中には、水の無い場合を参照基準にして、水分量に応じた吸収があることを示す。すなわち、水分量に応じて電波強度が低下する。右には、この傾向を示している。このように、電磁波の吸収量(電磁波強度の低下量)から水分だけの重量WH2Oを測定できる。既知の水分量に対して較正すれば、重量が求まる。特に、電子レンジに使われるマイクロ波が使用して都合がいい。水を加熱して昇温することが目的ではないので、弱い強度で瞬時に測定が可能である。尚、載置台510の下側に電磁波受波手段530を設けたが、反射波を測定すれば、載置台510の上側に電磁波受波手段530を設けることができる。電磁波受波手段530は、水による吸収がされたあとの電磁波の強度を測定するものである。尚、載置台510以外に、オムツや水分吸収シート、採便・採尿容器等の尿便受け体210は、電磁波の吸収性が低く透過性であることがよいのは当然である。 On the mounting table 510, the urine 220 and the stool 230 exist together on the urine / feces receptacle 210. An electromagnetic wave having a known intensity is irradiated from the electromagnetic wave irradiation means 520 and passes through the urine / feces receptacle 210, the urine 220 and the stool 230. The urine / feces receptacle 210, the mounting table 510, and the stool solid are not absorbable with respect to electromagnetic waves or are weaker than water. As electromagnetic waves, microwaves, millimeter waves, and terahertz waves are absorbed by water. In the middle of the figure, it is shown that there is absorption according to the amount of water with reference to the case without water. That is, the radio wave intensity decreases according to the amount of moisture. On the right, this trend is shown. Thus, the weight WH2O of only moisture can be measured from the amount of electromagnetic wave absorption (the amount of decrease in electromagnetic wave intensity). If you calibrate against a known amount of moisture, you can determine the weight. In particular, it is convenient to use microwaves used in microwave ovens. Since the purpose is not to raise the temperature by heating water, measurement can be performed instantaneously with a weak intensity. Although the electromagnetic wave receiving means 530 is provided on the lower side of the mounting table 510, the electromagnetic wave receiving means 530 can be provided on the upper side of the mounting table 510 if the reflected wave is measured. The electromagnetic wave receiving means 530 measures the intensity of the electromagnetic wave after being absorbed by water. In addition to the mounting table 510, the urine / stool receiving body 210 such as a diaper, a moisture absorbing sheet, and a stool / urine collection container naturally has low electromagnetic wave absorbability and is permeable.

FIG. 7 shows an embodiment of a flow of a method for calculating each amount of urine and stool from a measurement value of a stool solid part (heavy) amount in the measurement flow of the weight measurement method for separating urine and stool according to the present invention. FIG.
The difference from FIG. 3, instead of the water weight W H2 O measurements, is to measure the solids weight H stool, as a result, stool weight calculated M B and urine weight calculated U is a formula shown in FIG. 7 Sought after,
Stool weight calculation M B = H / (1-r)
Urine weight calculation U = M−M B = M−H / (1−r).
The calculated value is output.
In order to measure the weight H of the stool, the weight is measured after removing water. Centrifugation and high-temperature heating are well known as treatments for removing water and can be used.
FIG. 8 shows an apparatus corresponding to the flow of the method for calculating each amount of urine and feces from the measured value of the stool solid part (heavy) amount in the measurement flow of the weight measuring method for separating urine and feces according to the present invention. It is a figure which shows one embodiment of a structure. The difference from FIG. 4 is that the stool solid weight measurement H measurement means 810 and the water removal means 820 are replaced with a water weight WH 2 O measurement means 430.

尿又は便が混在せず、単独である場合にも、水分重量WH2O、便の固形物重量Hから計算を行う両者とも、計算式は使える。例えば、水分重量WH2Oから求める場合で、尿のみの場合では、固形物はないので、r=0、尿量U=WH2O、WH2Oは、Mに等しい。MB=0となり、式は満足されている。逆に、便のみの場合、便の重量MBは全重量Mに等しい。
便の水分は、rMB=rMであるから、尿重量U=WH2O―rM=0(両者は等しいため)、
便重量MB=(M−WH2O)/(1−r)=(M−rM)/(1−r)=Mとなり、前重量Mが便の重量になる。これも式が満足されている。
今度は、便の固形物重量Hから求める場合で、尿のみの場合では、固形物はないので、r=0、又、H=0であるので、MB=0、尿量U=Mとなり、尿量Uは、全重量になる。
これも式が満足されている。逆に、便のみの場合は、便重量Mは全重量Mに等しいので、尿重量U=0となり、便重量MB=H/(1−r)で計算され、式が満足されている。
Even when urine or stool is not mixed and used alone, the calculation formula can be used for both of calculating from the moisture weight W H2O and the solid weight H of the stool. For example, in the case of obtaining from the moisture weight W H2O , in the case of urine alone, there is no solid matter, so r = 0, urine volume U = W H2O , W H2O is equal to M. M B = 0 and the equation is satisfied. Conversely, if only stools, weight M B of the stool is equal to the total weight M.
Since the stool moisture is rM B = rM, urine weight U = W H2O -rM = 0 (because both are equal),
Stool weight M B = (M−W H2O ) / (1−r) = (M−rM) / (1−r) = M, and the previous weight M becomes the weight of the stool. This also satisfies the formula.
This time, it is calculated from the solid weight H of the stool. In the case of urine alone, there is no solid matter, so r = 0 and H = 0, so that M B = 0 and urine volume U = M. The urine volume U is the total weight.
This also satisfies the formula. Conversely, in the case of only stool, since the stool weight M B is equal to the total weight M, the urine weight U = 0, and the stool weight M B = H / (1-r) is calculated, and the equation is satisfied. .

以上のように本発明にかかる尿と便を分別した重量測定方法とその装置では、両者が混在した場合でも、両者の量を区別して把握できるので、医療や介護等の患者の状態管理に使用され、産業上利用して極めて好都合である。 As described above, the weight measurement method and apparatus for separating urine and stool according to the present invention can distinguish and grasp the amount of both, even when both are mixed, so it can be used for patient management such as medical care and nursing care. It is very convenient for industrial use.
