The procedure to place antegrade hemodynamic support (AHS) combine currently available procedures and devices in a unique fashion to solve a significant problem for patients who need large bore hernodynarnic support. The AHS procedure involves delivering an AHS device or a catheter connected to an AHS device to a patient's aorta in an antegrade fashion, alleviating the workload on the patient's heart and supporting the patient hemodynamically to maintain normal functions of the body organs.

The invention provides a stator split moving iron core type permanent magnet linear oscillating motor, which belongs to the field of linear oscillating motors, wherein the outer stator iron cores are symmetrically distributed on both sides of the inner stator permanent magnets; the movable iron cores are symmetrically distributed at equal intervals Between the outer stator core and the inner stator permanent magnet; the resonant spring is sleeved on the movement shaft; the movement shaft is connected to the geometric center of the side end of the mover iron core support; the armature winding includes two sets of coils, which are connected by a sinusoidal AC source; the inner stator permanent magnet includes several sub-permanent magnets of equal size, and the magnetization directions are all vertical directions, and the magnetization directions of adjacent sub-permanent magnets on the horizontal side are different; when the magnetization directions of adjacent sub-permanent magnets on the vertical side are opposite When the inner stator core is added between the permanent magnets of the two poles, the two sets of coils are connected in reverse series or reverse parallel; otherwise, the two sets of coils are connected in series or parallel in the same direction; the present invention prolongs the service life of the permanent magnets, and at the same time The output thrust density is improved, and the noise and vibration of the motor operation are reduced.

A tilt sensor for signaling when the tilt sensor is not vertical. The tilt sensor includes a metallic ball that is free to move and capable of resting at a low point when the tilt sensor is vertical. A proximity sensor directed at the low point communicates when the metallic ball has deviated from its position of repose, indicating that the sensor is no longer vertical.

The invention provides a water surface tamping device for a foundation pile of civil engineering, and relates to the technical field of civil engineering. A support groove is formed on the edge of the top surface of a seat cushion table, and a plurality of vertical strips are evenly opened inside the seat cushion table and located directly below the support groove. Straight movable channel, the movable channel runs downward through the bottom surface of the working boat, and the inner wall of the movable channel is symmetrically opened with a limit channel, and the top of the movable channel is embedded with a quill, and the inner wall of the quill is embedded with an air bag; the inner wall of the movable channel is movable A movable rod is connected, and the bottom end of the outer wall of the movable rod is symmetrically opened with an inner groove. The soil is input from the input pipe to the loose soil position, and the soil is transported to the loose soil position. The soil is filled with soil, which can replenish soil in time and strengthen soil tightness. It can improve the firmness of building foundation piles, solve the problem that the underwater environment is harsh, and the soil quality is poor, and it is very difficult to compact the foundation piles. Most of the work is done by artificial launching and compaction, and the work process is low. , and the problem of poor performance.
