Contribution of a winged phlebotomy device design to blood splatter.

Background: Despite a proliferation of phlebotomy devices with engineered sharps injury protection (ESIP), the impact of various winged device designs on blood splatter occurring during venipuncture procedures has not been explored.

Objectives: To evaluate the potential for blood splatter of 6 designs of winged phlebotomy devices.

Design: A laboratory-based device evaluation without human subjects, using a simulated patient venous system.
