摘要:
The invention is a self-venting blood collection needle assembly for the extraction of at least one fluid sample into an evacuated container for laboratory testing, this blood collection needle assembly providing a clear or translucent flashback chamber for blood to flow into, for visualization by the user to confirm successful vein entry. The self-venting mechanism permits escape of air during use, and which, typically, also prevents an outflow of fluid, such as blood. Thus, air under venous pressure will be allowed to escape from the blood collection needle assembly until blood reaches the venting mechanism.

The blood collection set includes an IV needle assembly, a length of flexible plastic tubing extending from the IV needle assembly and a non-patient needle assembly. The set is formed with a venting mechanism that permits an outflow of air, while blocking an outflow of blood or other fluids. Thus, the venting mechanism enables air that had existed in interior portions of the blood collection set to be vented allowing for greater flash visualization on venous entry, and avoids the need to employ a discard tube.

A substrate having an anti-adhesive coating thereon. The coating is made from a coating composition comprising solid particles of a release agent different from boron nitride and a binder comprising surface-modified nanoscale solid particles.
摘要:
A method for producing a ceramic coating of metallic and/or ceramic surfaces and products in reactors, process plants and combustion plants includes applying a mixture of fine-particle boron nitride, at least one inorganic binding agent of medium particle size in the nanometer range, containing substantially Al2O3, AlO(OH), ZrO2, Y—ZrO2, TiO2, Fe2O3 and/or SnO2 or an associated precursor compound and at least one solvent and/or water onto a metallic and/or ceramic surfaces or product, and burning the applied mixture into a coating through heating.
