Claims (13)
- 負圧で創傷を治療する装置であって、
前記装置は、創傷カバー(1)と、創傷(5)に前記負圧を提供するための第1のポンプ(9)と、キャニスタ(6)と、前記創傷カバー(1)と前記キャニスタとの間の第1の導管(8)であって、前記創傷(5)を前記キャニスタと接続する第1の導管(8)と、前記キャニスタ(6)内で圧力を測定するための手段と、前記キャニスタを前記第1のポンプと接続する第2の導管(1)と、を含む装置において、
循環ポンプ(12)は、気体を前記キャニスタ(6)から創傷領域へ第3の導管(13)を介して移送させるように、且つ前記第1の導管(8)から前記キャニスタ(6)へ可能な液柱を押し出すために前記キャニスタ(6)へ前記第1の導管(8)を介して戻すように配置されることを特徴とする装置。 - 前記循環ポンプ(12)は、断続的に作動するように配置されることを特徴とする請求項1に記載の装置。
- 前記循環ポンプ(12)は、該循環ポンプ(12)が止まる期間中に、前記第1の導管(8)内に構築されることができる可能な液柱の最大限の高さを制御するために、時間制御されることを特徴とする請求項2に記載の装置。
- 前記キャニスタ内で圧力を測定するための前記手段は、圧力センサー(11)であることを特徴とする請求項1〜3のいずれか一項に記載の装置。
- 逆止弁(14)は、前記循環ポンプ(12)によって送り出された気体が、少なくとも前記逆止弁(14)と前記創傷(5)との間の空間に進入することを阻止するように配置されることを特徴とする請求項1〜4のいずれか一項に記載の装置。
- 前記逆止弁(14)は、前記創傷カバーの接続ブランチ内に配置されることを特徴とする請求項5に記載の装置。
- 前記創傷カバー(1)は、創傷充填剤(2)及びシールフィルム(3)を含むことを特徴とする請求項1〜6のいずれか一項に記載の装置。
