Adaptor for use with point-of-care testing cartridge

摘要

An adaptor (10) is provided to facilitate delivery of a fluid specimen from a syringe to a point-of-care testing cartridge. The adaptor (10) includes opposed proximal (70) and distal ends (72) and a passage (74) extending between the ends. The proximal (70) end of the adaptor (10) defines a Luer fitting (75) configured for mating with a Luer tip of a syringe. The distal end (72) of the adaptor defines a small diameter nose (84) configured for insertion into the entry port of a testing cartridge. An outlet passage (82) extends through the nose (84) and is dimensioned to create small droplets of liquid that can be delivered easily to the testing cartridge. Radially aligned fins (92) are disposed proximally of the nose (84) and define channels between the fins for enabling venting of air from the testing cartridge.
