Therapuetic Diffusion Hydrocolloid Wound Dressings with Methods of Oxygen Level Indication

摘要: A wound dressing has a reservoir between not-permeable upper layer, and lower permeable an adhesion layer facing in the direction of to be pressed skin patient around wound, sealing patient, one or other oxygen-level indicator containing material exhibiting color change with varying concentration oxygen, placed visible person viewing through interface not open oxygen second intimate contact reservoir, self-sealing opening which hollow tube may pass without allowing escape, useful for charging at pressure, sampling by external probe.
