Description
本出願は、2017年3月8日出願の米国仮特許出願第62/468,796号の利益を主張するものであり、その開示は参照によりその全体が本明細書に組み込まれる。
一部のTNP装置のユーザインタフェースは、それを介してユーザがユーザ入力を提供できる限定的な要素を持ちうる。一部の実例では、特定のユーザインタフェースは、ユーザによって使用可能な単一要素を含んで、陰圧の送達を停止および開始をすることができ、ユーザは単一要素を別の要素と交換またはやり取りすることができない場合がある。これらの特定のユーザインタフェースは、多数の要素を有するより複雑なユーザインタフェースより構築して操作することがより簡単であることが望ましい場合がある。しかし、特定のユーザインタフェースは、単一要素がフォルト(例えば、故障など)を経験し、ユーザ入力を受信するように機能できなくなる場合に問題を呈しうる。特定のユーザインタフェースのユーザは、陰圧がまだ提供されていない場合、陰圧の送達を不所望に開始できない場合があり、陰圧が提供されている場合に陰圧の送達を不所望に停止できない場合がある。
図1はTNP装置11および創傷14を含む陰圧療法システム100を示す。TNP装置11は創傷14を治療するために使用され得る。TNP装置11には、相互に電気的に通信するように構成された、制御回路12Aと、メモリ12Bと、陰圧源12Cと、ユーザインタフェース12Dと、電源12Eと、第一の圧力センサ12Fと、第二の圧力センサ12Gと、皮膚検出器12Hとが含まれ得る。さらに、TNP装置11には創傷被覆材13が含まれ得る。電源12Eは、TNP装置11の一つ以上の構成要素に電力を供給することができる。
本明細書で提供される閾値、限界値、期間などの値は、絶対的なものであることを意図するものではなく、したがっておおよそのものでありうる。さらに、本明細書で提供される任意の閾値、限界値、期間などは、自動的にまたはユーザによって、固定されるかまたは変えられうる。さらに、本明細書で使用される場合、参照値に関連した、超える、超、未満などの相対的な程度を表す用語は、参照値と等しい場合も包含することが意図される。例えば、正の参照値を超えることは、参照値以上であることを包含することができる。その上、本明細書で使用される場合、参照値に関連した、超える、超、未満などの相対的な程度を表す用語は、参照値に関連した、下にある、未満、超などの開示された関係とは逆のものも包含することが意図される。また、種々のプロセスのブロックは、ある値が特定の閾値に達するかまたは達しないかを判定することに関して説明されうるが、ブロックは、例えば、ある値が(i)閾値未満であるかもしくは閾値を超えているか、または(ii)閾値を満たすかもしくは満たしていないかに関しても同様に解釈されうる。
特定の開示によって制限されることを意図するものではなく、本節においてまたは本明細書の他の箇所において提示されているか、またはこの後に提示される特許請求の範囲によって定義されうる。本特許請求の範囲の言い回しは、本特許請求の範囲で用いられている言い回しに基づいて広い意味で解釈されるべきであり、本明細書で説明されている例または本出願の手続きの間に説明される例に限定されるものではなく、それらの例は非排他的なものとして解釈されるべきである。
