Abstract
【解決手段】多孔性の外傷用医薬材料1.0と、流体が流れるように外傷用医薬材料に接続されたキャニスタ8と、外傷用医薬材料とキャニスタとの間に配置された第1のバルブとを具え、第1のバルブは、開放位置と閉鎖位置とに位置決めされ、処分用の管14が、流体が流れるようにキャニスタに接続されており、開放位置と閉鎖位置とに位置決めされる第2のバルブを具え、ポンプ11が、流体が流れるようにキャニスタに接続されており、第1のバルブが開いており第2のバルブが閉じているときに、外傷用医薬材料からキャニスタに創傷の浸出液を吸引し、ポンプは、第1のバルブが閉じており第2のバルブが開いているとき、キャニスタから処分用の管に創傷の浸出液を押し出す構成とする。

Description
本出願は、参照によりここに組み込まれている、2005年12月6日に出願された米国暫定出願第60/742,755の優先権を主張する。
Claims (6)
- 創傷を閉塞および隔離する装置であって、
平均的な孔の大きさが約200ミクロンよりも小さい網状の連続気泡発泡体の外傷用医薬材料であって、創傷の近くに配置可能な発泡体の外傷用医薬材料と、
前記発泡体と前記創傷を覆うドレープと、
約125mmHgよりも低い圧力で前記創傷から創傷の浸出液を吸い出すべく、流体が流通するように前記発泡体の外傷用医薬材料に接続されたポンプであって、創傷の排水と、前記創傷の湿度制御を保守するが、組織が前記発泡体の外傷用医薬材料内に増殖するのを最小にするポンプと、を具えることを特徴とする装置。 - 請求項1に記載の装置において、前記発泡体の外傷用医薬材料の平均的な孔の大きさが、約100ミクロンよりも小さい、あるいはこれと等しいことを特徴とする装置。
- 請求項1に記載の装置において、前記発泡体の外傷用医薬材料の孔の大きさにより、組織が内側に増殖するのを最小にするが、前記創傷からの流体の排水が可能であることを特徴とする装置。
- 請求項1に記載の装置において、前記圧力が、約25乃至75mmHgの間であることを特徴とする装置。
- 請求項1に記載の装置がさらに、
前記創傷の浸出液を収集すべく、前記発泡体の外傷用医薬材料と前記ポンプとの間に配置されるキャニスタであって、排水用出口を具えるキャニスタを具え、
前記ポンプが、前記排水用出口を介して前記キャニスタから創傷の浸出液を押し出すよう選択的に作動することを特徴とする装置。 - 請求項5に記載の装置がさらに、
流体が流通するように前記排水用出口に配置可能な使い捨て容器を具え、前記キャニスタから創傷の浸出液を収集することを特徴とする装置。
