Abstract
An oximetry probe assembly includes fluid seal assembly taking the form of a manually actuated plunger which moves relative to a barrel having a seal placed therein. Depression of the plunger causes the seal to be deformed so as to permit insertion of an oximetry probe through the seal and advancement towards a central venous catheter. When the plunger is released, the seal is compressed against the barrel and the sheath of the oximetry probe to thereby form a fluid-tight seal. The plunger and barrel are preferably configured as a one-handed grasping assembly whereby the user may hold the plunger and barrel with one hand, press the plunger with the thumb, and advance the oximetry probe through the fluid seal assembly with the other hand.
