Abstract
Description
以下、本発明の一実施形態について、詳細に説明する。
点眼補助具の概要について、図3を参照しながら以下に説明する。図3は、本実施形態に係る点眼補助具1の使用例を示す。
補助具本体10は、図1に示すように、略円筒状であり、点眼液を収容した点眼容器30を着脱自在とする装着部である。補助具本体10の周囲には、点眼容器30を出し入れするための第1開口部10aと、第1開口部10aに対向する位置に、当該第1開口部10aよりも小さな第2開口部10bとが形成されている。これにより、この補助具本体10に、点眼容器30の点眼吐出部30aを接眼ガイド20側に向けて、当該点眼容器30の点眼液収容部30bを装着すれば、当該点眼液収容部30bの一部が第1開口部10aと第2開口部10bとから露出する。ユーザは、補助具本体10から露出した点眼容器30の点眼液収容部30bを指で直接押さえることで、当該点眼液収容部30bに収容された点眼液を点眼吐出部30aから吐出させることができる。
接眼ガイド20は、補助具本体10に連接され、図3に示すように、患者1の眼101の周囲に接触する部分である。接眼ガイド20と補助具本体10は一体的に形成されていてもよいし、別々に形成されていてもよい。
点眼補助具1の接眼ガイド20による位置決めについて、図1,図3および図4を参照しながら以下に説明する。
図5は、点眼補助具1を用いた点眼実験を行う際の各種条件を説明するための図である。図6は、点眼補助具1を用いた点眼実験を行う際の、点眼距離、点眼角度による点眼の成功率を説明するための図である。
ベクトルOX=d1/2(cosθ、sinθ)
ベクトルXQ=d3(cos(θ+π/2)、sin(θ+π/2))
ベクトルQR=h(cosθ、sinθ)
となり、瞳101cにおける下眼瞼から液滴端の距離H1は(1)で表すことができる。
すなわち、H1は、ベクトルORのX成分から液滴半径のd2/2を引いた値となる。
すなわち、H2は、ベクトルORのX成分と液滴半径のd2/2を、d1cosθから引いた値となる。
図7は、ずれ量hを2mmとしたときに、式(1)、(2)を用いて傾斜角θ、点眼距離d3を変えて求めた値を示す表である。図中の(1)(2)は、それぞれ式(1)(2)に対応する。
以上のように、上記構成の点眼補助具1によれば、点眼対象者が座位あるいは立位姿勢であっても、適切に点眼することができる。このように、点眼液を正確に点眼できることで、薬剤の効果が十分に発揮される。その結果、眼疾患の治癒期間の短縮、患者の精神的な負担の軽減や医療費の大幅な抑制効果が期待される。しかも、点眼補助具1の構造がシンプルなため、製造コストを抑え、しかも、壊れにくいという効果も奏する。
点眼補助具1等の点眼デバイスに、カメラ、LED(light emitting diode:発光ダイオード)ライトやセンサを組み込むことで、患者の投薬実態を把握することが出来る。
図10は、点眼デバイスとして点眼補助具1を用いた患者の点眼管理を行うための投薬管理システムの概略ブロック図を示している。
点眼補助具1には、専用の製剤を装着して投薬管理を行うために、時計、カウンタ、カメラ、メモリ、LEDライト、バッテリー、バッテリーインジケータ、通信機能(Bluetooth(登録商標)4.0、WiFi(登録商標))、バーコード読取り機能、ICタグ読取り機能、アラーム鳴動機能が搭載されている。これにより、点眼補助具1を用いて、以下に示す基本的な投薬管理を行うことが可能となる。
(8)残滴量管理:容器内の残液量と使用可能な期間を示すことで、点眼液の残滴量管理を行う。
スマートフォン401として搭載している機能を用いて以下示す基本的な投薬管理を行うことが可能となる。
基本的に、パーソナルコンピュータ402では、スマートフォン401ができる機能を実行することができる。パーソナルコンピュータ402において、スマートフォン401ができる機能以外でできる機能として、少なくとも以下のような機能を実行することができる。
(点眼補助具1の操作)
点眼補助具1による製剤認識の方法として、ソフトウェアによる製剤認識を行う方法と、ハードウェアによる製剤認識を行う方法がある。なお、点眼補助具1には、電源スイッチは存在しなく、電池が装着し、電源が有る限り駆動し続けるものとする。
点眼補助具1は、搭載したカメラを製剤のバーコード表示部分に向け。そして、バーコードの読取り完了すると「ピピッ」と鳴る。これで製剤の種類の登録が完了する。登録完了した製剤のノズルの向きを合わせて点眼補助具1にセットする。
製剤には、製剤の種類により製剤を入れた点眼容器30の点眼吐出部30aに突起があり、それぞれの製剤により突起の位置が異なる。この製剤を点眼吐出部30aのノズルの向きを合わせて点眼補助具1にセットする。これにより、点眼吐出部30aに形成された突起の位置により点眼補助具1にセットされた製剤の種類が認識され、当該点眼補助具1に登録される。
スマートフォン401には、投薬管理システムで用いるための点眼補助具1専用のアプリケーションがインストールされているものとする。
クラウドサーバは、インターネット上でクラウドコンピュータ404と管理サーバ405とで構築されており、データベース機能と解析表示機能とを有している。クラウドサーバには、スマートフォン401を通して、日々若しくは一定の期間のデータがロードされる。ロードは、スマートフォン401上に蓄積されたデータを当該スマートフォンの表示画面に表示された「保存」をクリックすることで実行される。
