Qosina (Edgewood, NY) has introduced a needle hub sample kit as a prototyping tool set for designers and engineers. The combination of hub connector, bushing, and cap allows for the creation of a fluid delivery or withdrawal system. The kit contains 24 polycarbonate hubs in round, rectangular, octagonal, and anatomic body styles. Each hub comes in 14 G, 15 G, 16 G, and Universal size. Pre-drilled caps to match different body types are color-coded for each size. Spin lock collars can be added to the four hubs featuring a male luer slip connector for conversion to a rotating male luer lock.
