Description

尿量測定システム及びそれを用いた尿量管理データの作成方法、ならびに、尿量管理データ作成端末Urine volume measurement system, urine volume management data creation method using the same, and urine volume management data creation terminal
　本発明は、超音波素子を用いて膀胱内の蓄尿量を測定する尿量測定システム、及び、そのシステムを用いて尿量管理データを作成する方法、ならびに、上記尿量管理データを作成する尿量管理データ作成端末に関するものである。 The present invention relates to a urine volume measuring system that measures the amount of urine stored in the bladder using an ultrasonic element, a method for creating urine volume management data using the system, and a urine that creates the urine volume management data. The present invention relates to a quantity management data creation terminal.
　従来から、排尿機能に障害を持った患者の膀胱内に溜まった尿量（蓄尿量）を測定する尿量測定器としては、超音波を膀胱に向けて発信し、膀胱壁面からの反射波を受信することで膀胱内の蓄尿量を測定するものが知られており、その一例として、特許文献１に記載されたものが挙げられる。この種の超音波を利用した尿量測定器によれば、所定の測定周期毎に測定した膀胱内の蓄尿量を測定時刻と関連付けて記憶することができるため、その測定結果を医師等の医療従事者や患者本人等に提供することにより、患者の自立的な排尿を支援するのに役立つ。 Conventionally, as a urine volume measuring instrument that measures the amount of urine collected in the bladder of a patient with impaired urination function (urine accumulation volume), an ultrasonic wave is transmitted toward the bladder and the reflected wave from the bladder wall surface is transmitted. A device that measures the amount of accumulated urine in the bladder by receiving the signal is known, and an example thereof is described in Patent Document 1. According to this type of urine volume measuring device using ultrasonic waves, the amount of accumulated urine in the bladder measured at every predetermined measurement cycle can be stored in association with the measurement time. By providing it to workers, patients, etc., it helps to support the patient's independent urination.
　ところで、排尿障害のうち、特に尿意と排尿や蓄尿量との連携に障害が生じる過活動膀胱等の症状を改善するにあたっては、行動療法すなわち膀胱訓練が有効であることが知られている。そして、このような膀胱訓練においては、時刻に関連付て排尿量や尿意等のデータを一定期間継続して記録する排尿日誌が活用されている。この排尿日誌は、医療従事者が患者の排尿に関する症状を客観的に把握するためのものである。特に、尿意を知覚した時刻が含まれる情報は、患者自身が自己の症状を認識できると共に、医療従事者は患者の自覚症状と実際の膀胱機能を把握することが可能であること等から、患者の排尿習慣に合った適切な膀胱訓練を計画するにあたって非常に有益なものとなっている。 By the way, it is known that behavioral therapy, that is, bladder training, is effective in improving symptoms such as overactive bladder in which dysuria is particularly impaired in coordination between urination and urination and urine accumulation. In such bladder training, a urination diary that records data such as the amount of urination and urine content continuously for a certain period in association with the time is utilized. This urination diary is for medical personnel to objectively grasp symptoms related to urination of patients. In particular, the information that includes the time at which urinary perception was perceived is that the patient can recognize his / her symptoms and the medical staff can grasp the patient's subjective symptoms and actual bladder function. It is very useful in planning proper bladder training that fits your urination habits.
　しかしながら、現状において、排尿日誌のような尿量管理データを作成するにあたっては、患者自身が尿意や排尿量をその都度計測し表などに記録を付ける必要があるため、患者にとって大きな負担となっている。また、このような記録を付ける作業は患者の記憶に依存せざるを得ないため、必ずしも正確なデータを得ることができない場合が考えられ、その場合には、上記排尿日誌に記録される尿量管理データは客観性を欠き、患者に合った適切な膀胱訓練を実施することができなくなるという問題がある。
　そこで、このような尿量管理データの作成に上記尿量測定器を利用することにより、患者にできるだけ負担をかけることなく正確なデータを取得することが望まれている。 However, at present, when creating urine volume management data such as a urination diary, it is necessary for the patient himself to measure urine and urine volume each time and record it in a table, which is a heavy burden on the patient. Yes. In addition, since the operation of attaching such a record must be dependent on the patient's memory, it may not always be possible to obtain accurate data. In that case, the urine volume recorded in the urination diary Management data lacks objectivity, and there is a problem that appropriate bladder training suitable for patients cannot be performed.
Therefore, it is desired to obtain accurate data without imposing a burden on the patient as much as possible by using the urine volume measuring device for creating such urine volume management data.

　次に、本実施形態で用いられている膀胱内に蓄積された尿量すなわち蓄尿量の算出方法について説明する。
　まず、超音波素子１１から発信された超音波は組織間の境界において反射される。そのため、超音波素子１１から膀胱に向けて発信された超音波は膀胱の前壁と後壁とで反射し、この反射波が超音波素子１１で受信される。 Next, a method for calculating the amount of urine accumulated in the bladder used in this embodiment, that is, the amount of accumulated urine will be described.
First, the ultrasonic wave transmitted from the ultrasonic element 11 is reflected at the boundary between tissues. Therefore, the ultrasonic wave transmitted from the ultrasonic element 11 toward the bladder is reflected by the front wall and the rear wall of the bladder, and the reflected wave is received by the ultrasonic element 11.
　図３は、各超音波素子１１にて受信される反射波の波形の概略図である。該概略図は、縦軸を反射強度、横軸を発信からの時間とした図で表される。ここで、ｉ番目の超音波素子１１にて受信した波形のうち前壁からの反射波のピーク強度をＰｉ、前壁及び後壁からの反射波強度のピーク間距離をＤｉとすると、膀胱内の蓄尿量ＥＵは、以下の式（１）、（２）に基づいて算出することができる。
　ＰＤｊ＝ΣＰｉ×Ｄｉ　　　　　　　　　　　　　　　　　　　　　　　　・・（１）
　ＥＵ＝ＰＤ×Ｒ　　　　　　　　　　　　　　　　　　　　　　　　　　　・・（２）
　ここで、ＰＤｊは測定指標値、ＥＵは推定される膀胱内の蓄尿量、ＰＤは後に詳述する平均指標値、Ｒは解剖構造に基づく個人差や測定中の姿勢に対応して定められる係数を示す。また、ＰＤｊのｊは後述する所定の発信周期で発信される超音波の順番を意味しており、ここでは１から１０までの整数となっている。また、Ｐｉ，Ｄｉのｉは前記超音波プローブ１０に設けられた複数の超音波素子１１に付された番号を意味しており、ここでは１から４までの整数となっている。 FIG. 3 is a schematic diagram of the waveform of the reflected wave received by each ultrasonic element 11. The schematic diagram is represented by a graph with the vertical axis representing the reflection intensity and the horizontal axis representing the time from transmission. Here, if the peak intensity of the reflected wave from the front wall of the waveform received by the i-th ultrasonic element 11 is Pi and the distance between the peaks of the reflected wave intensity from the front wall and the rear wall is Di, The urine accumulation amount EU can be calculated based on the following equations (1) and (2).
PDj = ΣPi × Di (1)
EU = PD × R (2)
Here, PDj is a measurement index value, EU is an estimated urine accumulation amount in the bladder, PD is an average index value described in detail later, and R is a coefficient determined corresponding to individual differences based on the anatomical structure and the posture being measured. Indicates. Moreover, j of PDj means the order of ultrasonic waves transmitted at a predetermined transmission cycle to be described later, and is an integer from 1 to 10 here. Further, i in Pi and Di means numbers assigned to the plurality of ultrasonic elements 11 provided in the ultrasonic probe 10, and is an integer from 1 to 4 here.
　すなわち、上記蓄尿量算出部２４ｂでは、一定の測定周期毎、例えば１分毎に１回、膀胱内の蓄尿量を算出する。また、上記超音波素子１１は、この１回の測定周期における畜尿量を算出するために、超音波を一定の発信周期毎、例えば０．１秒毎に１回、計１０回（一秒間）発信する。従って、各発信周期における測定指標値ＰＤｊは、各超音波素子１１で受信される反射波の反射強度Ｐｉとピーク間の距離Ｄｉとの積をｉ＝１～４につき加算することにより得ることができ、その結果、１回の測定周期において１０個の測定指標値ＰＤｊを得ることができる。そして、これら測定指標値ＰＤｊ（ｊ＝１～１０）に対して適宜の平均化処理を行うことで、平均指標値ＰＤを得ることができ、該平均指標値ＰＤに係数Ｒを乗ずることで、各測定周期における膀胱内の蓄尿量ＥＵを算出することができる。
　なお、このようにして算出された蓄尿量ＥＵは、時系列的に上記測定データ記憶部２３ａに記憶される。図５は、上記測定データ記憶部２３ａに記憶されている各時刻（１分毎の測定周期）における蓄尿量を表形式にして表したものである。 That is, the urine accumulation amount calculation unit 24b calculates the urine accumulation amount in the bladder once every certain measurement period, for example, once every minute. In addition, the ultrasonic element 11 calculates the amount of livestock urine in one measurement cycle, for example, once every fixed transmission cycle, for example, every 0.1 second, for a total of 10 times (one second). )send. Therefore, the measurement index value PDj in each transmission period can be obtained by adding the product of the reflection intensity Pi of the reflected wave received by each ultrasonic element 11 and the distance Di between the peaks for i = 1 to 4. As a result, ten measurement index values PDj can be obtained in one measurement cycle. Then, by performing an appropriate averaging process on these measurement index values PDj (j = 1 to 10), an average index value PD can be obtained, and by multiplying the average index value PD by a coefficient R, The urine accumulation amount EU in the bladder in each measurement cycle can be calculated.
The urine accumulation amount EU calculated in this way is stored in the measurement data storage unit 23a in time series. FIG. 5 shows the amount of urine stored at each time (measurement cycle per minute) stored in the measurement data storage unit 23a in the form of a table.
　次に、図１、図４－図１２を用いて、本実施形態における尿量測定システム１について、より具体的に説明する。
　上記入力部２２は、被測定者が尿意を知覚した際に尿意信号を入力する尿意入力部２２ａを有している。図４に示すように、上記尿意入力部２２ａは、上記入力部２２を構成する複数の操作子のうち何れか一の操作子から成っており、当該操作子を押圧することで該尿意入力部２２ａに尿意信号が入力され、当該尿意信号の入力時刻（押圧時刻）に対応する尿意時刻が、上記測定データ記憶部２３ａに記録されるように構成されている。なお、図６は、測定データ記憶部２３ａに記録される上記尿意時刻を表形式で表したものである。 Next, the urine volume measurement system 1 in the present embodiment will be described more specifically with reference to FIGS. 1 and 4 to 12.
The input unit 22 includes a urinary input unit 22a that inputs a urinary signal when the measurement subject perceives urinary intention. As shown in FIG. 4, the urine input unit 22a is composed of any one of the plurality of operators constituting the input unit 22, and the urine input unit is pressed by pressing the operator. The urinary signal is input to 22a, and the urinary time corresponding to the input time (pressing time) of the urinary signal is recorded in the measurement data storage unit 23a. FIG. 6 shows the urine time recorded in the measurement data storage unit 23a in a tabular format.
　上記尿意入力部２２ａに尿意信号が入力された際、上述したように、その尿意時刻が測定データ記憶部２３ａに記憶されると共に、その尿意時刻に対応する尿意時蓄尿量が上記演算部２４で算出される。そして、尿意時蓄尿量は、演算部２４における比較部２４ａで所定のアラーム閾値（アラーム尿量）と比較され、図７（ａ）、図７（ｂ）に一例として示すように、該尿意時蓄尿量が上記表示部２６に表示される。上記比較部２４ａで比較されるアラーム尿量は、例えば、予め定められた値であってもよいが、上記入力部２２を介して被測定者や医療従事者等が入力したものであってもよく、適宜の値とされる。 When a urinary signal is input to the urinary input unit 22a, as described above, the urinary intention time is stored in the measurement data storage unit 23a, and the urinary urine storage amount corresponding to the urinary intention time is stored in the arithmetic unit 24. Calculated. The urinary retention amount is compared with a predetermined alarm threshold (alarm urine amount) by the comparison unit 24a in the calculation unit 24, and the urinary retention amount is shown as an example in FIGS. 7 (a) and 7 (b). The amount of accumulated urine is displayed on the display unit 26. The alarm urine volume to be compared by the comparison unit 24a may be, for example, a predetermined value, or may be input by a person to be measured, a medical worker, or the like via the input unit 22. It is often an appropriate value.
　本実施形態においては、上記尿意時蓄尿量は、尿意入力部２２ａに尿意信号が入力された入力時の直前の測定周期における蓄尿量に基づいて算出されている。具体的には、この尿意時蓄尿量は、尿意入力部２２ａの尿意信号の入力時に、上記測定データ記憶部２３ａに記憶された最も直近の蓄尿量と成っている。
　そして、上記比較部２４ａは、その尿意時蓄尿量値と上記アラーム尿量とを比較し、尿意時蓄尿量がアラーム尿量の所定割合（例えば８０％）を超えない場合には、例えば、数値で示すなど、被測定者に対し排尿を行う必要はないことが認知できるように表示される。このように、尿意入力部２２ａに尿意信号を入力（操作子を押圧）すれば、上記表示部２６を介して尿意時蓄尿量が数値化されると共に、比較部２４ａによる比較結果が数値として表示されるため、例えば、被測定者が、膀胱内の蓄尿量が僅かであるにも関わらず尿意を知覚した場合であっても、排尿を行う必要性がないことが分かり、それに伴い、次第に膀胱内に尿を満たすことができる時間を増やし、排尿間隔を広げていくことができる。 In the present embodiment, the urinary retention amount is calculated based on the urine storage amount in the measurement period immediately before the input when the urinary signal is input to the urine input unit 22a. Specifically, the urine storage amount at the time of urination is the latest urine storage amount stored in the measurement data storage unit 23a when the urinary intention signal is input to the urine input unit 22a.
Then, the comparison unit 24a compares the urinary urine accumulation amount value with the alarm urine amount, and if the urine intention urine accumulation amount does not exceed a predetermined ratio (for example, 80%) of the alarm urine amount, for example, a numerical value For example, it is displayed so that it can be recognized that there is no need to urinate to the measurement subject. In this way, if a urinary signal is input to the urine input unit 22a (the operator is pressed), the amount of urine stored during urine is digitized via the display unit 26, and the comparison result by the comparison unit 24a is displayed as a numerical value. Therefore, for example, it is found that there is no need to urinate even when the subject perceives urinary urgency even though the amount of accumulated urine in the bladder is small. The time that urine can be filled in is increased, and the interval between urinations can be increased.
　なお、上記尿意時蓄尿量は、測定ばらつきなどを考慮して、尿意信号の入力時の直前の測定周期における複数の蓄尿量値に基づいて尿意時蓄尿量を求めてもよい。この場合、例えば、上記尿意入力部２２ａへの尿意信号入力時に、測定データ記憶部２３ａに記憶された複数の蓄尿量値から最大値と最小値とを除いた蓄尿量の平均として求めることもできる。また、尿意信号の入力時に、上記測定データ記憶部２３ａに記憶された複数の蓄尿量値から補間して尿意時蓄尿量を求めることでもよい。 Note that the urinary urine storage amount may be obtained based on a plurality of urine storage amount values in the measurement cycle immediately before the input of the urinary signal in consideration of measurement variation and the like. In this case, for example, when a urinary signal is input to the urine input unit 22a, it can be obtained as an average of the urine storage amount obtained by removing the maximum value and the minimum value from a plurality of urine storage amount values stored in the measurement data storage unit 23a. . In addition, when a urinary signal is input, the urinary urine storage amount may be obtained by interpolation from a plurality of urine storage amount values stored in the measurement data storage unit 23a.
　或いは、上記尿意時蓄尿量は、尿意入力部２２ａに尿意信号が入力された入力時に、上記超音波素子１１によって超音波を膀胱に向けて発信し、その反射波に基づいて上記蓄尿量算出部２４ｂで算出された蓄尿量値であってもよい。この場合には、上記尿意時蓄尿量は、各測定周期単位で推測され記憶された過去の蓄尿量に基づくものではなく、尿意入力部２２ａに相当する上記操作子が押圧された時点で測定された蓄尿量値となる。 Alternatively, the urine storage amount at the time of urine is transmitted from the ultrasonic element 11 toward the bladder when the urine signal is input to the urine input unit 22a, and the urine storage amount calculation unit is based on the reflected wave. The urine accumulation value calculated in 24b may be used. In this case, the urinary urine storage amount is not based on the past urine storage amount estimated and stored in each measurement cycle unit, but is measured when the operation element corresponding to the urine input unit 22a is pressed. It becomes the urine accumulation amount value.
　被測定者の膀胱内の蓄尿量値はモニタリングされており、蓄尿量算出部２４ａで算出された蓄尿量のうち最大蓄尿量がＭＡＸ値として上記記憶部２３に記録される。具体的には、演算部２４において、測定周期毎に得られる蓄尿量と記憶部２３に記録されているＭＡＸ値とを比較して、蓄尿量がＭＡＸ値を超えた場合には、その蓄尿量値が新たなＭＡＸ値として記憶部２３に記録される。また、上記ＭＡＸ値は、上記記憶部２３から読み出され、例えば図４に示すように、上記表示部２６（画面右上）に表示される。また、出力部２５からの出力時において上記記憶部２３からＭＡＸ値を読み出し、例えば蓄尿量や尿意時刻等と共に出力されてもよい。
　このＭＡＸ値は数時間～１日間の測定により、被測定者の膀胱内に貯められる大凡の最大蓄尿量となり、以後の膀胱訓練の目安となる。また、ＭＡＸ値が表示部２６等に表われることに伴い、被測定者は自身の膀胱内に、より多くの尿が保持されるようになることを自覚する。 The urine accumulation amount value in the bladder of the measurement subject is monitored, and the maximum urine accumulation amount among the urine accumulation amount calculated by the urine accumulation amount calculation unit 24a is recorded in the storage unit 23 as the MAX value. Specifically, in the calculation unit 24, the urine accumulation amount obtained for each measurement cycle is compared with the MAX value recorded in the storage unit 23, and when the urine accumulation amount exceeds the MAX value, the urine accumulation amount The value is recorded in the storage unit 23 as a new MAX value. The MAX value is read from the storage unit 23 and displayed on the display unit 26 (upper right of the screen), for example, as shown in FIG. Further, at the time of output from the output unit 25, the MAX value may be read from the storage unit 23 and output together with, for example, the amount of urine stored or the urine time.
This MAX value is an approximate maximum amount of urine stored in the bladder of the subject, measured for several hours to one day, and is a measure for subsequent bladder training. Further, as the MAX value appears on the display unit 26 or the like, the measurement subject realizes that more urine is retained in his / her bladder.
　また、本実施形態における上記演算部２４は、上記記憶部２３に記憶されたデータに基づいて、少なくとも所定の測定周期毎の蓄尿データ、尿意時刻を含む尿意データ、及び、蓄尿データに基づいて算出された排尿量とその排尿時刻とを含む排尿データを、時系列的に並べて尿量管理データを作成する管理データ作成部２４ｃを有している。この管理データ作成部２４ｃは、例えば、測定データ記憶部２３ａに記憶されている各時刻における蓄尿量と尿意時刻とが合成されることで、尿量管理データが作成される。この尿量管理データは、上記出力部２５から出力され、または表示部２６に表示されるように構成されている。 Further, the calculation unit 24 in the present embodiment is calculated based on the data stored in the storage unit 23 based on at least urine accumulation data for each predetermined measurement cycle, urinary data including urinary time, and urine accumulation data. There is a management data creation unit 24c that creates urine volume management data by arranging the urination data including the urination volume and the urination time in time series. For example, the management data creation unit 24c creates urine volume management data by synthesizing the urine accumulation amount and the urinary intention time stored at each time stored in the measurement data storage unit 23a. The urine volume management data is output from the output unit 25 or displayed on the display unit 26.
　上記尿量管理データは、過活動膀胱などの被測定者に対する排尿日誌として使用することができ、例えば、尿量管理データの例として、図８に示すように、各時刻における蓄尿量（１分毎の測定周期）と、被測定者が尿意を知覚して尿意入力部２２ａに尿意信号が入力された時刻と、排尿量とその時刻とを時系列的に表形式で表したものがある。また、本実施形態では、上記尿量管理データに最大蓄尿量としてのＭＡＸ値が表れている。 The urine volume management data can be used as a urination diary for a person to be measured such as overactive bladder. For example, as an example of urine volume management data, as shown in FIG. For each measurement cycle), the time when the person to be measured perceives urinary intention, and the urinary signal is input to the urinary input unit 22a, and the amount of urination and the time are expressed in a time-series table format. Moreover, in this embodiment, the MAX value as the maximum urine accumulation amount appears in the urine volume management data.
　排尿量と排尿時刻とについては、上記演算部２４によって、上記測定データ記憶部２３ａに記憶された各時刻毎の蓄尿量の時間的変化から、蓄尿量が大きく減少する時刻に基づいて算出される。具体的には、上記演算部２４における排尿量算出部２４ｄで、上記測定データ記憶部２３ａに記憶されたある時刻における蓄尿量と、その次の時刻における蓄尿量との尿量差が比較されると共に、その差が、上記記憶部２３に記憶された所定の排尿閾値以上になる時刻を探して、排尿閾値以上のときの尿量差を排尿量として算出されて、該排尿量が上記表示部２６に表示され又は出力部２５に出力されるようになっている。排尿閾値を設定するのは、測定誤差に基づく若干の尿量減少を「排尿」と判断しないためである。なお、この排尿閾値は予め設定されていてもよく、或いは、上記入力部２２を通じて被測定者等が設定することでもよい。なお、排尿閾値としては、例えば５０ｃｃが挙げられるが、この値に限られるものではない。 The urination amount and the urination time are calculated by the calculation unit 24 based on the time when the urine storage amount greatly decreases from the temporal change of the urine storage amount at each time stored in the measurement data storage unit 23a. . Specifically, the urine volume calculation unit 24d in the calculation unit 24 compares the urine volume difference between the urine storage amount at a certain time stored in the measurement data storage unit 23a and the urine storage amount at the next time. In addition, the time when the difference becomes equal to or greater than the predetermined urination threshold stored in the storage unit 23 is calculated, and the urine volume difference when the difference is equal to or greater than the urination threshold is calculated as the urination amount. 26 or output to the output unit 25. The reason why the urination threshold is set is that a slight decrease in urine volume based on the measurement error is not determined as “urination”. The urination threshold may be set in advance, or may be set by the measurement subject or the like through the input unit 22. An example of the urination threshold is 50 cc, but is not limited to this value.
　図８では、上記尿意時刻を、尿意入力部２２ａに尿意信号が入力された時点の時刻としているが、当該尿意時刻を、尿意信号の入力時刻付近で上記蓄尿量算出部２４ｂにより蓄尿量が算出された時刻として表示されていてもよい（図９参照）。或いは、図１０に示すように、縦軸を蓄尿量、横軸を時刻とする棒グラフで表現すると共に、上記尿意時刻を矢印などの記号を用いて示すこともできる。なお、図１０では、５分間隔毎の蓄尿量値が棒グラフとして表示されており、１１時２０分と１１：３０分との間で蓄尿量値が急激に下がっていることから、この間で排尿があったことが視認できる。 In FIG. 8, the urinary intention time is the time at which the urinary intention signal is input to the urinary input unit 22a. The urine retention time is calculated by the urine accumulation amount calculating unit 24b near the input time of the urinary intention signal. It may be displayed as the set time (see FIG. 9). Alternatively, as shown in FIG. 10, while representing the urine accumulation amount on the vertical axis and the bar graph with the horizontal axis representing time, the urinary intention time can also be indicated using symbols such as arrows. In FIG. 10, the urine accumulation value at intervals of 5 minutes is displayed as a bar graph, and since the urine accumulation value is drastically decreased between 11:20 and 11:30, urination is performed during this period. It can be visually recognized that there was.
　また、本実施形態においては、尿量管理データを、上記測定データ記憶部２３ａに記憶された各時刻における蓄尿量と尿意時刻とを対比して、当該尿意時刻に対応する膀胱内の蓄尿量を抽出すると共に、上述した排尿量を算出する方法から排尿時刻を算出し、排尿時刻における蓄尿量を抽出することで、図１１に示す表形式のように表示することもできる。なお、図１１では、排尿時刻における蓄尿量が抽出されているが、それに加えて、排尿時刻直前に算出された蓄尿量も抽出して図１２のように出力されていてもよい。このような尿量管理データによれば、尿意時刻、及び、排尿量と排尿時刻における膀胱内の蓄尿量のみが表わされ、これらは排尿日誌においてポイントとなる活動のみが表れているため、例えば、病院の受診の際に有効に利用される。 Further, in the present embodiment, the urine volume management data is compared with the urine accumulation amount at each time stored in the measurement data storage unit 23a and the urine intention time, and the urine accumulation amount in the bladder corresponding to the urine intention time is calculated. In addition to the extraction, the urination time is calculated from the above-described method for calculating the urination amount, and the urine accumulation amount at the urination time is extracted, so that the table can be displayed as shown in FIG. In FIG. 11, the urine accumulation amount at the time of urination is extracted, but in addition to this, the urine accumulation amount calculated immediately before the urination time may also be extracted and output as shown in FIG. According to such urine volume management data, only the urine intention time, and the urination volume and the urine accumulation amount in the bladder at the time of urination are represented, and these represent only the activity that is the point in the urination diary, for example, It is used effectively when visiting a hospital.
　また、管理データ作成部２４ｃで作成された尿量管理データは、例えば、上記記憶部２３における管理データ記憶部２３ａに記憶させることもでき、当該尿量管理データを必要なときに該管理データ記憶部２３ａから読み出すことも可能である。 Further, the urine volume management data created by the management data creation unit 24c can be stored in, for example, the management data storage unit 23a in the storage unit 23, and the urine volume management data is stored when necessary. It is also possible to read from the unit 23a.
　本実施形態の尿量測定システム１によれば、排尿日誌等のような尿量管理データを作成するにあたり、当該被測定者が蓄尿量（排尿量）や尿意時刻等をその都度計測する必要がなく、当該尿量管理データが自動的に作成されるため、被測定者に対する負担が小さく、簡単且つ正確に作成することができる。また、本実施形態で作成される尿量管理データは、膀胱内の各時刻における蓄尿量、尿意時刻、及び、排尿量とその時刻とが時系列的に関連付けられていることから、被測定者自身が尿意と各時刻における蓄尿量（排尿量）との関係を視覚的に理解できる形で作成され、医療従事者においても、該尿量管理データによって被測定者の自覚症状と実際の膀胱機能とを把握することができ、被測定者に合った適切な膀胱訓練を計画することができる。 According to the urine volume measuring system 1 of the present embodiment, when creating urine volume management data such as a urination diary, the person to be measured needs to measure the urine storage volume (urination volume), urinary intention time, etc. each time. However, since the urine volume management data is automatically created, the burden on the person to be measured can be reduced and can be created easily and accurately. In addition, the urine volume management data created in the present embodiment has the urine accumulation amount, the urinary intention time, and the urination volume at each time in the bladder, and the urine volume and the time are correlated in time series. Created in such a way that the user can visually understand the relationship between urinary intention and the amount of urine stored (urine output) at each time, and even in the medical staff, the subject's subjective symptoms and actual bladder function And appropriate bladder training suitable for the measurement subject can be planned.
