Vascular needle for connection of blood vessel with source of fluid i.e. physiological saline solution, has distal capsule-shaped connecting section inserted into container, and expansion element provided for radial expansion of section

摘要

The needle (1) has a distal capsule-shaped connecting section inserted into a container. A proximal connecting part (3) i.e. luer lock, is provided for a source of fluid and a flow channel i.e. oblong pipe, penetrating the needle. An expansion element (6) i.e. screw sleeve, is provided for radial expansion of a connecting section (5), where the connecting section consists of a flexibly expandable material at an end. The expansion element partly surrounds the flow channel and relocatable in a longitudinal direction.
