Differential air pressure systems
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.
1. A differential air pressure system, comprising:
a positive pressure chamber with a seal interface configured to receive a portion of a user's body and form a seal between the user's body and the chamber;
a height adjustment assembly attached to the chamber adjacent to the seal interface; and a control panel attached to the height adjustment assembly.
2. The system of claim l, wherein said positive pressure chamber comprises at least one transparent panel.
3. The system of claim 2 , wherein said positive pressure chamber comprises a plurality of transparent panels.
4. The system of claim 1 , wherein said positive pressure chamber comprises a slip resistant panel.
5. The system of claim 4 , wherein said slip resistant panel is adjacent to the seal interface.
6. The system of claim 2 , wherein the height adjustment assembly comprises a horizontally actuated locking mechanism.
7. The system of claim 2 , wherein said height adjustment assembly comprises two movable ends located within two corresponding adjustment posts.
8. The system of claim 7 , wherein each movable end comprises at least two rollers.
9. The system of claim 8 , further comprising a first roller that is orthogonally oriented with respect to a second roller.
10. The system of claim 8 , wherein each movable end comprises at least one movable braking pad.
11. The system of claim 10 , wherein at least one movable braking pad may be actuated by tilting the height adjustment assembly.
12. The system of claim 11 , wherein said height adjustment mechanism further comprises a counterbalancing system configured to at least partially offset the weight of said movable assembly.
13. The system of claim 12 , wherein said counterbalancing system comprises a weight located at least one adjustment post.
14. The system of claim 1 , further comprising a platform attached to the chamber using a seal mechanism.
15. The system of claim 14 , wherein the seal mechanism is configured to increase sealing to the platform with increased pressure within chamber.
16. The system of claim 14 , wherein the sealable mechanism further comprises a foam member.
17. The system of claim 2 , further comprising a pin latch locking mechanism configured to lock the present position of said user seal.
18. A differential air pressure system, comprising:
a pressure chamber; and
a vertically adjustable cantilevered frame having a first movable configuration and a second locked configuration wherein the second locked configuration is actuated by the pressure chamber.
