Abstract: A contrast therapy system. According to one aspect of the invention, the contrast therapy system includes a hot reservoir for holding a relatively hot fluid and a cold reservoir for holding a relatively cold fluid. The system also includes a mixing valve for receiving a selected ratio of the hot and cold fluids from the hot and cold reservoirs. The mixing valve is operable to deliver a therapy fluid with a therapy temperature determined by the selected ratio. The system also includes a therapy pad for receiving the therapy fluid from the mixing valve and returning the therapy fluid to at least one of the hot reservoir and the cold reservoir.

Abstract: A fluid circuit connector system includes a quick-release connector for connecting a set of tubes to an object. The quick-release connector includes a release button, a lock arm, a lock tab and a cavity configured to receive the tubes and a set of coupler housings. The connector system includes an object fitting having lock recess may be configured to receive the lock tab. The object fitting includes a cavity. The system further includes a set of male coupler housings each including a first unitary valve and a set of female coupler housings each including a second unitary valve. Each female housing is configured to receive and engage one of the male coupler housings. The system includes a set of seals configured to seal each male coupler housing and each female coupler housing when the quick-release connector is connected to the object fitting.
