Abstract

Described herein are various embodiments of differential air pressure systems and methods of using such systems. The differential air pressure system may comprise a chamber configured to receive a portion of a user's lower body and to create an air pressure differential upon the user's body. The differential air pressure system may further comprise a user seal that seal the pressure chamber to the user's body. The height of the user seal may be adjusted to accommodate users with various body heights.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A differential air pressure system comprising:
 an inflatable chamber comprising a flexible user seal configured to releasably seal a portion of a user's body inside the chamber;   a frame assembly having a base, wherein the inflatable chamber is attached to the base; and   a movable assembly comprising a seal frame attached to the chamber, wherein the movable assembly is configured to adjust the height of the user seal by vertically moving the seal frame.
