TELESCOPIC DEVICE Russian patent published in 2015 - IPC A61M25/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Telescopic urine catheter contains first telescopic part and second telescopic part. Second telescopic part is placed with possibility of travel in first telescopic part in first and second axial directions along longitudinal axis of first telescopic part. Connective device for limitation of displacement of second telescopic part with respect to first telescopic part is made with possibility to take first and second connective configurations and has connective part, external surface of which is provided with central part and first and second conical surfaces, and surrounding it laid up ring. First connective configuration limits displacement in first axial direction, making it possible for displacement in opposite second axial direction. Second connective configuration limits displacement in second axial direction, making it possible for displacement in opposite first axial direction. Connective device has possibility of selective transition from first connective configuration into second connective configuration, and vise versa, when force exceeding specified level is applied to second telescopic part in axial direction, displacement of which is limited in first or second connective configuration.

EFFECT: invention provides increased convenience of application due to reversible telescoping from compact condition.
