Abstract: A back support (1) for a pedal driven device or other device including a saddle which provides a seat for a user of the device, includes a mount (2) which may be releasably engageable with the device. A contact part (4) which is configured to contact the back of the user of the device, is movably mounted in operative connection with the mount in an articulated manner. The exemplary contact part includes a bracket (7, 20) that is rotatable relative to the mount about a bracket axis (14). The bracket operatively connects the mount and contact bodies (6, 23, 24, 26, 27, 31, 32). The contact bodies are movably mounted in rotatable operative connection with the bracket about respective contact body axes (9, 28, 30) which extend parallel to the bracket axis.

Abstract: A carrying device for a portable gas exchange device has at least one first holding strap which is designed to be worn around a torso of a patient, thereby allowing the carrying device to be supported on the patient. The carrying device further includes a fastener which is designed to fasten a portable gas exchange device. Also provided is a carrying system which consists of a carrying device and a gas exchange device.

Abstract: A device for treating a biological liquid has a housing with a first chamber defining a cavity and which is adapted to receive a liquid to be treated. At least one gas exchanger is at least partly disposed in the first chamber. An inlet portion is formed in a first surface of the housing for the inlet of the liquid to be treated into the chamber. The inlet portion is formed at an acute angle relative to the surface of the housing. Such a device allows a gas exchange in a lung assist method for example.
