Abstract: The invention relates to a tube (100) with a hollow cylindrical elastic base structure (102) for insertion into a blood vessel (200) of a vascular system (202). The tube (100) comprises an outer anisotropic surface structure (104) comprising a geometrical anisotropy between a direction circumferential to the tube and a direction longitudinal to the tube (100). The anisotropic surface structure (104) is configured for establishing an anisotropic friction between the anisotropic surface structure (104) and an inner surface of the blood vessel (200). The anisotropic friction results in a surface propulsion of the tube (100), when the tube (100) is rotated around a central longitudinal body axis (106) of the tube (100). The tube (100) further comprises a magnetic material (108) distributed circumferentially around the tube (100) and configured for establishing within an external magnetic field a rotation of the tube (100) around the central longitudinal body axis (106) of the tube (100).

Abstract: Disclosed is an electronic skipping rope structure comprising two skipping rope handles (1A, 1B) and a rope (2). The skipping rope handles (1A, 1B) each comprise a fixed handle (10) for being grasped and a rotating body (11) which is movably connected with the fixed handle (10) and is connected with the rope (2). A sensing point (11A, 11B, 11C) is arranged on the rotating body (11) of one skipping rope handle (1A), and at least two detecting points (10A, 10B, 10C) corresponding to the sensing point (11A, 11B, 11C) are arranged on the fixed handle (10) of the skipping rope handle (1A), said fixed handle (1A) having arranged inside it a micro-controller (3) electrically connected with the detecting points (10A, 10B, 10C). The electronic skipping rope structure increases the accuracy of counting and features a simple structure and low costs. Also provided is an electronic skipping rope competition system.

Abstract: A wireless skipping-rope handle comprises a handle shell (1) provided with a rotating head (11). A micro-controller (2) and a counting switch (3), a button (5), a memory (6), and a wireless module (7) connected thereto are provided in the handle shell (1). The wireless module (7) is also connected with an antenna (71). A console and a skipping-rope carpet device which are wirelessly connected to the wireless skipping-rope handle are also provided.
