図5は、実施形態1に係る測定部210の内部構造の一例を模式的に示す図である。具体的には、図5は、測定部210を構成する撮影部212のフィルムに係る構造の例を示すものである。図5に示すように、撮影部212は、フィルムを一方のリールから張架して他方のリールに巻き取る二つのリールを含み、測定の開始都度または測定の終了都度の自動でリールを回転させることで前記フィルムを排尿が流れ込んだ溜水に順次送り出して浸漬させることができる。
図6は、実施形態2に係る測定部210の内部構造の一例を模式的に示す図である。測定部210は、図6に示すように、仕切り40bを基準に上部と下部の2層に分けて、仕切り40bから上部(使用済みのフィルムが巻き取られたリール20bの配置側)を廃棄部として、仕切り40bから下部(未使用のフィルムが巻き取られたリール10bの配置側)を使用部とすることもできる。廃棄部は、使用済みの水溶性のフィルムを便器内の溜水に溶解させることで廃棄するための格納スペースとして用いてもよい。
ここで、本実施の形態において、一例として、記憶部130に記憶される各種DBのデータ構成の例について図8を用いて説明する。なお、各種DBはそれぞれ、サーバ100の記憶部130を記憶先として限定せず、測定装置200の記憶部250でもよいし、ユーザ端末300の記憶部330でもよい。また、当該データ構成は、サーバ100の機能構成、処理内容等によって適宜変更してもいいことは言うまでもない。
以上、各種DBのデータ構成である。
図9は、健康モニタリングシステム100が実行する処理の一例を示すフローチャートである。
記憶部130は、予め初期設定として、または、測定の都度、便器のボウルの形状情報、溜水の水量情報、溜水の水温情報を記憶する(ステップS11)。ユーザ識別部220は、ICカード、ユーザ端末300等を用いて使用者を識別する(ステップS12)。なお、当該ステップ後に、測定部212は、一旦、溜水の水温を測定してもよい(不図示)。照度センサ部213は、フィルム面の照度を測定する(ステップS13)。測定部210は、使用者から手動で制御部230に備える入力手段で測定開始が入力されたことを伝達された場合は、各測定を開始する(ステップS14)。なお、当該ステップは、電極部211、撮影部212、温度測定部214が測定開始を自動で行う場合は省略することができる。
本発明に係る健康モニタリングシステムは、医療機関等と連動して、遠隔医療の一環として利用することができる。例えば、記憶部130に記憶するユーザDBの中に各ユーザが係る医療機関、医師等の情報を記憶し、測定・検査結果DBの更新の際等に当該DBの測定値および検査結果データを上記医療機関等に送信し、医師等は、当該送信されたデータに基づいて、患者が自宅にいても遠隔から健康に関する診察、指導等を行うことができる。
