| abstract |
A method for starting an intravenous fluid line (IV) is disclosed where a combination of a syringe body with hypodermic needle, a dual ampoule with separate reservoirs for bicarbonate and an anesthetic, a trocar and a cannula are configured so that the steps of injecting a wheal of a buffered anesthetic, retracting the needle tip, lancing a vein with the trocar, and withdrawing the trocar tip so that the cannula remains in place in the vein may be accomplished in a single coordinated action by one skilled in the method, such as with one hand while the other hand performs manipulations on the vein and IV site. |
