A system and method for exchanging fluid between a body compress and a fluid source. In the preferred embodiment, an air pump is used to compress the fluid in the container and force it into the compress. When the motor is turned off, the fluid flows back from the container to the compress. By cycling the motor between 'on' and 'off' conditions, a circulation of fluid occurs between the compress and the container.

Automatic fluid circulating system and method

A check value for controlling fluid flow comprises two sleeves connected to one another in fluid-tight engagement and a flexible membrane disposed across an interior cross-section of the engaged sleeves. The flexible membrane is secured to the sleeves along less than the membrane's full circumference, so that the unsecured portion of the membrane can flex to allow fluid to flow through the sleeves in one direction. The membrane resists fluid flow in the opposite direction.
