Abstract: The present disclosure discloses a storage strap winding structure for a contraction tensioner, including a ratchet strap tension apparatus, a movable strap, a strap winding shaft, etc. Mainly, the strap winding shaft internally provided with a mandrel which coaxially penetrates, and a strap outlet groove exposing the mandrel is arranged on the strap winding shaft. In this way, it is only necessary to connect a winding end of the movable strap to a mandrel through a strap outlet groove, and the winding end can be wound on the strap winding shaft layer by layer by the rotation of the strap winding shaft to form a storage strap. Obviously, due to the design of the mandrel and the strap outlet groove, the winding end of the movable strap does not need to pass before sewing and connecting, thus ensuring the simplification of the production process.

Abstract: Extract intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds) by not only reducing steady noise (such as low-frequency-range environmental sounds or noise) but also reducing unexpected noise (such as high-frequency-range cries or speaking voices). This keeps up the intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds), while reducing the unexpected noise (such as high-frequency-range cries or speaking voices), using an improved adaptive filter unit and an improved nonlinear filter unit. Here, a reduction level of the unexpected noise (such as high-frequency-range cries or speaking voices) and a level of keeping up the intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds) are quantitatively calculated.

Abstract: A flexible intestinal anastomosis stent which sucks secretions on an inner wall of an intestinal tract and at a suture site into a horn-shaped channel through a through-hole. The secretion is discharged to an inside of the stent body through a liquid-inlet hole after being squeezed by intestinal tract contents, thereby reducing a risk of infection at the suture site. A lower edge of the outlet end of the stent body has a concave polygonal structure, each reflex angle at a lower edge of the concave polygonal structure being formed with one inwardly folded wrinkle structure on a side wall of the stent body, and the wrinkle structure also able to accommodate the secretions. The lower edge is stressed and deformed by the intestinal tract contents to reduce a reflex angle, so that secretions in the wrinkle structure are discharged downwardly, such that risk of complications is reduced.
