The presence of microplastics in the human body and their potential health risks have drawn widespread attention recent years. Microplastics been detected blood, though pathways entry remain unclear. This study employed Raman spectroscopy energy dispersive to evaluate microplastic release characteristics intravenous medical devices, aiming investigate influencing factors risk entering bloodstream. results showed that were found three widely-used with abundances ranging from 0.44 2.00 items/n. Polyethylene, polypropylene (46.2 %), fragments (96.7 white (86.8 %) predominant characteristics. Factors such as brand, specifications, usage scenarios influence release, leading differences detection rates among different devices (0-100%). Repeated use significantly increases (p < 0.05). Notably, built-in filtration membranes do not completely retain may pose a shedding fibers themselves. Using exposure assessment model, estimated per person year was 3.75 items for syringe, 6.22 infusion set, 0.35 vein detained needle. Overall, although amount through injection is lower than dietary other pathways, direct into bloodstream remains concern. research provides critical evidence understanding blood plastic offering significant scientific value assessing safety device use.
