Manually-operated negative pressure wound therapy (NPWT) bandage with improved pump efficiency, automatic pressure indicator and automatic pressure limiter

摘要

A new and improved NPWT bandage which is simple, inexpensive, easy-to-use, small in size (including having a low profile), is atraumatic to the wound during use, has improved pump efficiency, incorporates an automatic pressure indicator for indicating the level of negative pressure created, and provides an automatic pressure limiter for limiting the level of negative pressure created.
