Abstract: The invention relates to an applicator for a nasal cannula, comprising a body (11) enclosing a hollow space (22). The applicator further comprises tube connections (20, 21) for supplying a respirable gas into the hollow space (22). The applicator further comprises prongs (18, 19) for administering the respirable gas into the nostrils of a person. A valve (15, 16, 17, 38, 42) is located in a wall of the body (11) so that respirable gas can flow from the outside through the valve into the hollow space (22), but not in the reverse direction. The invention further relates to an applicator having a top of sealing cones (23, 24), wherein the sealing cones (23, 24) may be provided with rim-shaped sealing lips on their side facing away from the body (11), which produce a tight seal with the inner wall of the respective nostril.

Abstract: This invention pertains to a hose system for an injector for injecting contrast agents and saline solution into the human body. The hose system comprises a contrast agent conduit (106, 126; 206, 226; 306, 326; 401, 402, 403, 404, 405, 421, 422, 423, 424, 425; 501, 502, 503, 504, 521, 522, 523, 524), a saline solution conduit (116, 216, 316, 411, 412, 413, 414, 415; 511, 512, 513, 515) a pump hose (132; 232; 332; 432; 532) and a frame (135; 235; 335; 435, 436; 535, 536, 537). The contrast agent and saline solution conduits are mechanically fixed at a least one position to the frame. The pump hose is fixed to the frame at least two positions. The invention further pertains to a squeeze valve and a pressure measuring interface.
