Non-stick syringe needles: Beneficial effects of thin film metallic glass coating
Scientific Reports, 2016 AbstractThis paper reports on the use of Zr-based (Zr53Cu33Al9Ta5) thin film metallic glass (TFMG) for the coating of syringe needles and compares the results with those obtained using titanium nitride and pure titanium coatings. TFMG coatings were shown to reduce insertion forces by ∼66% and retraction forces by ∼72%, when tested using polyurethane ...

Preclinical studies of non-stick thin film metallic glass-coated syringe needles [PDF]
Scientific Reports, 2020 AbstractOur objective in this study was to determine the biocompatibility and hemocompatibility of thin film metallic glass (TFMG) and its potential use in hypodermic needles for intramuscular or intravenous injection. Mouse and rabbit models were employed under approval from the Institutional Animal Care and Use Committee (n = 5/group, two groups in ...

Administration of Anesthetics Using Metal Syringes. An Ex Vivo Study [PDF]
Anesthesia Progress, 2011 Abstract The aim of the present study was to assess injection flow rates of metal syringes, with an emphasis on injection speed and the generation of flow pulsations. A cohort of 64 operators (32 practitioners and 32 students) performed 3 consecutive ex vivo simulated injections (SIs) of 1.8-mL cartridges of anesthetic solution.
