AI Technical Summary

Technical Problem

Existing sheath introducers face issues with blood stagnation, inadequate blood flow rate, and air ingress during dialysis due to structural limitations and incomplete sealing at the connection points.

Method used

A sheath adapter with a cylindrical tubular portion that passes through the sheath hub's valve, ensuring a direct blood flow path and sealing to prevent air ingress, featuring a uniform lumen cross-section and a stopcock for controlling blood flow.

Benefits of technology

Prevents blood stagnation and ensures a smooth, high-flow rate blood suction by creating a direct flow path and sealing the sheath hub, thereby maintaining blood purity during dialysis.

Abstract

To provide a sheath adapter capable of preventing stagnation of blood, securing a flow rate of the blood, and preventing air from being mixed with the blood.SOLUTION: A sheath adapter 100 is used for blood suction and includes a sheath connecting part 210 being connectable to a sheath hub proximal end 42 of a sheath introducer 10, a cylindrical part 220 capable of passing through a valve element 43 provided at the sheath hub proximal end 42, and a tube 300 attached to a proximal end 222 of the cylindrical part 220, where when the sheath connecting part 210 is connected to the sheath hub proximal end 42, a distal end 221 of the cylindrical part 220 penetrates the valve element 43 provided at the sheath hub proximal end 42 and is disposed inside a sheath hub 40, thereby communicating a lumen of the tube 300 disposed outside the sheath hub proximal end 42 with a sheath hub lumen 40s.SELECTED DRAWING: Figure 7
