Abstract
【解決手段】溶媒に低溶解性の水溶性樹脂とpH指示薬とを溶解し、pH緩衝液にてpH3〜5の酸性に調整した溶液を、中性で且つ吸水性を有する基材に塗布又は含浸した後乾燥して得たことを特徴とする。かかる構成により、基材に担持させたpH指示薬の周囲が、低溶解性の水溶性樹脂からなる薄膜で覆われるようになる。このため、この水溶性樹脂からなる薄膜が乾燥遅延材として機能し、基材に付着させた尿が乾燥するのを遅延させることができる。
【選択図】なし
Description
基材として市販の医療用6インチ綿棒を用意すると共に、下表1に示す条件でpH指示薬混合溶液を調製した。調製後のpH指示薬混合溶液のpHは概ね4であった。
そして、尿pH検査用具の綿球すなわちpH測定部位を各人工尿に浸漬した後、引き上げて、以下の項目について評価を行った。
(1)色の見やすさ;色覚に異常のない5名のパネラーが、pH測定部位に担持させたpH指示薬の色調の変化を、◎=「非常に見やすい」,○=「見やすい」,△=「やや見にくい」,×=「見にくい」の4段階で官能評価した。そして、最もよい結果と最も悪い結果とを除いたデータの中から最も多い評価のものを採用した。
(2)色落ち;5名のパネラーが、尿pH検査用具を人工尿に漬けて引き上げた後、ティッシュペーパー上に載置し、3分経過後にpH指示薬の色がティッシュに染みているかどうかを、◎=「ほとんど色落ちなし」,○=「多少色落ちあり」,△=「色落ち有り」,×=「色落ちが激しい」の4段階で官能評価した。そして、最もよい結果と最も悪い結果とを除いたデータの中から最も多い評価のものを採用した。
(3)発色の持続性;5名のパネラーが、尿pH検査用具を人工尿に漬けて引き上げた後、初期の発色状態から明らかに色調が変化するまでの時間を計測した。そして、最もよい結果と最も悪い結果とを除いたデータの中から最も多い評価のものを採用した。
本実施例及び比較例の尿pH検査用具に関する上記(1)〜(3)の評価結果を下表4に示す。
Claims (3)
- 溶媒に低溶解性の水溶性樹脂とpH指示薬とを溶解し、pH緩衝液にてpH3〜5の酸性に調整した溶液を、中性で且つ吸水性を有する基材に塗布又は含浸させた後乾燥して得たことを特徴とする尿pH検査用具。
- 前記水溶性樹脂がポリビニルアルコール,ポリアクリル酸,ポリアクリルアミド又はポリエチレンオキシドから選ばれる少なくとも1種であることを特徴とする請求項1に記載の尿pH検査用具。
- 前記pH指示薬がフェノールレッド,ブロモチモールブルー又はアントシアニンから選ばれる1種であることを特徴とする請求項1又は2に記載の尿pH検査用具。
