Thrombus suction sheath for dialysis access

Abstract

The invention discloses a thrombus suction sheath for a dialysis pathway, and relates to the technical field of medical instruments. Comprising a sheath tube and a sheath core, a second pressure plate is fixedly arranged on one side of the sheath tube, a first pressure plate is movably arranged on one side of the second pressure plate, fixing devices are movably arranged on the outer wall of the first pressure plate and the outer wall of the second pressure plate, and the first pressure plate and the second pressure plate are fixedly arranged on the sheath tube. Clamping rods are movably arranged in grooves of the first pressing disc and the second pressing disc, a fixing plate is fixedly arranged at one end of each clamping rod, a sliding block is fixedly arranged on one side of each fixing plate, and a rolling wheel is movably arranged on one side of each sliding block. By arranging the clamping grooves and the clamping rods on the first pressing disc and the second pressing disc, the first pressing disc and the second pressing disc are rapidly mounted and dismounted through clamping connection of the clamping rods and the clamping grooves of the pressing discs, the sheath tube and the sheath core are integrated, the clamping connection structure is stable, time consumed for dismounting and mounting is short, and dismounting and mounting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus suction sheath for dialysis access. Background technique [0002] A thrombus is a small piece of blood that forms on the surface of a vessel in the cardiovascular system where the lining has been peeled off or repaired. In the variable fluid-dependent form, the thrombus consists of insoluble fibrin, deposited platelets, accumulated leukocytes, and trapped erythrocytes. [0003] In the prior art, in the process of thrombus suction, if only the suction tube is used, it is easy to damage the intima of the blood vessel, and the sheath core is generally used. The connection between the existing sheath core and the suction tube is not stable enough, which is prone to Out of the situation, the existing suction structure lacks a supporting frame for placement, which is inconvenient to use. Contents of the invention [0004] The invention provides a thrombus suction...
