Abstract
Description
本発明の第1の実施の形態に係る流体経路検査装置は、図2に示すような被測定加圧手段(コンプレッサ)303と専用チューブ(4a1,4a2,4a3,4b1,4b2,4b3)を有する被測定機器3の流体経路を検査する流体経路検査装置である。即ち、第1の実施の形態に係る流体経路検査装置は、図1に示すような30kPa程度以下の低圧領域の加圧が可能な測定用加圧手段(コンプレッサ)34を有する。流体経路検査装置からは、専用チューブ(4a1,4a2,4a3,4b1,4b2,4b3)とは異なる検査チューブ4xjが出ており、エラーモード・ノーマルモード時には検査チューブ4xjのみで被測定機器3と流体経路検査装置とを接続している。被測定機器3の通常使用時には専用チューブ(4a1,4a2,4a3,4b1,4b2,4b3)が被測定機器3とスリーブ(ガーメント)とを接続している。流体経路検査装置と検査チューブ4xj(4a1,4a2,4a3,4b1,4b2,4b3)のみを接続してリーク検査を行う。検査チューブ4xjの経路を流体経路の一部として閉じた流体回路を構成し、測定用加圧手段34によって流体回路を加圧して一定時間保持することにより検査チューブ4xjのリークを検査するリーク検査ユニット21aと、図2に示すような圧力調整用比例電磁弁(V1a2,V1a4,V1a6,V1b2,V1b4,V1b6)を有し、被測定機器3の流体経路に発生する可能性のある複数の異常モードのそれぞれの流体回路特性を、被測定加圧手段303による流体圧力の加圧と圧力調整用比例電磁弁(V1a2,V1a4,V1a6,V1b2,V1b4,V1b6)による流体圧力の調整によってそれぞれエミュレートして、被測定機器3の流体経路の異常を検査する異常エミュレーションユニット21bとを備える。
(イ)第1の異常モード(エラーモードE1)は、医療機器の内部圧力が高くなると出る「システム高圧エラー」である。図34及び図35に示すようなスリーブ(ガーメント)301a,301bを下肢や足底に巻き付ける場合で説明すれば、例えば、「第1部位」として定義した「足底」にスリーブを巻き付ける場合は、医療機器の内部圧力が24kPa以上で「システム高圧エラー」と規定し、「第2部位」として定義した「下肢(レッグ)」にスリーブを巻き付ける場合は、医療機器の内部圧力が12kPa以上で「システム高圧エラー」と規定することができる。
ただし、これらの4つの異常モード(エラーモードE1,E2,E3,E4)は例示であり、被測定機器3が呈する流体経路の特性によって、2つ~3つの異常モードや、5つ以上の異常モードや他の異常モードを設定して、異常エミュレーションユニット21bがエミュレートするようにしても構わない。
図16~図24のフローチャートを用いて、「エラーモード(異常モード)」における本発明の第1の実施の形態に係る流体経路検査方法の処理の流れを説明する。なお、以下の図16~図24のフローチャートを用いた説明では、被測定機器3がIPCに用いる医療機器の場合に問題となる「システム高圧エラー」、「高圧エラー」、「低圧エラー」及び「システム低圧エラー」の4つの異常モード(エラーモードE1,E2,E3,E4)を前提として説明するが、これらの4つの異常モードは例示であり、被測定機器3が呈する流体経路の特性によって、2~3の異常モードや、5以上の異常モードや他の異常モードを設定しても構わない。即ち、4つの異常モードを用いた流体経路検査装置の動作は、簡単な説明をするための一例であり、特許請求の範囲に記載した趣旨の範囲内であれば、この変形例を含めて、これ以外の種々の異常モード、手順、順番、選択、動作方法等により、実現可能であることは勿論である。
図25~図28のフローチャートを用いて、「ノーマルモード(正常モード)」の場合における第1の実施の形態に係る流体経路検査方法における処理の流れを説明する。なお、以下に述べるノーマルモード(正常モード)の場合の流体経路検査装置の動作は、簡単な説明をするための一例であり、特許請求の範囲に記載した趣旨の範囲内であれば、この変形例を含めて、これ以外の種々の手順、順番、選択、動作方法等により、実現可能であることは勿論である。なお、図27のフローチャートでは、図面上の枠の大きさの制限から「被測定機器」を被測定機器3の一例であるSCDと略記し、「流体経路検査装置」をIPCDと略記して簡略化表現を用いて説明しているが、単なる便宜上の表記であり、「SCD]や「IPCD」が特定の意味を有するものではない。
図29~図33のフローチャートを用いて、「リーク検査」を選択した場合における本発明の第1の実施の形態に係る流体経路検査方法における処理の流れを説明する。なお、以下に述べる流体経路検査装置の動作は、簡単な説明をするための一例であり、特許請求の範囲に記載した趣旨の範囲内であれば、この変形例を含めて、これ以外の種々の手順、順番、選択、動作方法等により、実現可能であることは勿論である。なお、図29~図31のフローチャートでは、図面上の枠の大きさの制限から「被測定機器」を被測定機器3の一例であるSCDと略記し、「流体経路検査装置」をIPCDと略記して簡略化表現を用いて説明しているが、単なる便宜上の表記であり、「SCD]や「IPCD」が特定の意味を有するものではない。
上記のように、本発明は第1の実施の形態によって記載したが、この開示の一部をなす論述及び図面は本発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなろう。特に、第1の実施の形態の説明では「流体」が「空気」である場合について例示的に説明したが、本発明の「流体」は「空気」に限定されるものではなく、「流体」は酸素(O2)、窒素(N2)、ヘリウム(He)等の他のガスでもかまわない。また「流体」は水や油等の液体や水銀等の液体金属であっても構わない。したがって、本発明はここでは記載していない様々な実施の形態等を含むことは勿論である。よって、本発明の技術的範囲は上記の説明から妥当な特許請求の範囲に係る発明特定事項によってのみ定められるものである。
