This utility model belongs to the field of medical tools, specifically disclosing a hemostatic compression device for hemodialysis catheters, including a shawl, a compression airbag assembly fixed to the inside of the shawl, an air pump, and a pressure monitoring assembly. The compression airbag assembly includes at least two independent first and second airbags. The first airbag is a cylindrical, point-like compression airbag used to compress the internal jugular vein puncture site, and the second airbag is a long, rectangular, linear compression airbag used to comprehensively compress the subcutaneous tunnel. The two airbags are connected to the air pump connector via independent inflation tubes, and the connector contains a one-way valve. The shawl has a fixing and adjustment structure consisting of buckles and nylon hook and loop fasteners. This device achieves effective hemostasis at different bleeding sites after TCC catheter placement through a precise point-line compression method, replacing manual pressure. The hemostatic effect is clear and reliable, the operation is convenient, and the pressure is adjustable and controllable.

The invention discloses plate feeding equipment for furniture manufacturing and production, and relates to the technical field of furniture manufacturing, the plate feeding equipment comprises a frame body and supporting legs fixedly connected to the outer surface of the frame body; the discharging mechanism is arranged, the furniture plates can be placed, when the furniture plates are extruded by the pressing device, the furniture plates can still move, and the discharging mechanism is used for placing the furniture plates; the lifting device is arranged, the distance between the pressing device and the discharging mechanism can be changed, so that the pressing force on the furniture plates is adjusted, the pressing work of the furniture plates with different thicknesses is met, and the lifting device is used for adjusting the pressing force of the furniture plates and a fixing frame fixedly connected to the outer surface of the lifting device; and by arranging the pressing device, the furniture plates on the upper surface of the discharging mechanism can be extruded, and the effect of transporting and treating the plates with different thicknesses is achieved.

The invention provides a multifunctional friction mechanism with adjustable wedge gap, which solves the technical problem that the existing traction machine cannot adjust the friction force between the clamp and the formed body according to the actual production situation. The mechanism is provided with a left wedge block and a right wedge block, which are relatively arranged between a friction component fixing platform and a lower wedge block, and the left wedge block and the right wedge block are respectively slidably connected with the friction component fixing platform, the left wedge block is slidably connected to the left sliding inclined surface of the lower wedge block, the right wedge block is slidably connected to the right sliding inclined surface of the lower wedge block, and the bottom surface of the lower wedge block is connected with the friction block; the two ends of the forward and reverse lead screws are respectively adapted to be connected with the positive wire ear seat and the reverse wire ear seat, the positive wire ear seat is connected with the left wedge block, and the reverse wire ear seat is connected with the right wedge block; when the forward and reverse lead screws rotate, the left wedge block and the right wedge block slide back to back or relatively at the same time, and the lower wedge block approaches or moves away from the friction component fixing platform along a guide member, and the mechanism can be widely used in the technical field of textile equipment.
