Adjustable automated CPR positioning apparatus

An apparatus for selectively positioning a therapeutic device against a patient's body part, comprising:

• a support structure comprising a plurality of elements, each such element having a telescopic variable length, and said plurality of elements being connected one to another at respective ends thereof in the form of a chain;
• wherein the respective ends of each set of two adjacent elements are connected to each other by a hinge;
• and
• wherein the support structure is configured to selectively have a compact configuration, in which the plurality of elements are folded and arranged one against another, and an operable configuration, in which the plurality of elements are unfolded and arranged end-to-end completely around a body part of the patient;
• wherein an unconnected end of each of two most remote elements of the support structure may be selectively connected to each other by a connectable hinge, whereby the connectable hinge allows the unconnected ends of the two most remote elements to be selectively connected to each other to lock the support structure in the operable configuration;
• and
• wherein a first of the plurality of elements is configured to allow a therapeutic device to be movably mounted thereto and to be moved therealong, such that, when the support structure is in the operable configuration, the therapeutic device can be positioned precisely in a desired position against the patient's body part.
