Abstract
A multiple syringe pump, comprising a pump housing, two or more seating recesses therein to receive two or more syringes for delivering two or more different substances to a patient intravenously, such as nutritional elements in one and medication substances in another, and a corresponding plurality of drive mechanisms in said pump housing powered by an electrical source for connection to each of the two or more syringes seated in said pump housing to move the syringe plungers at a controlled rate in the direction to discharge the contents of the syringe cylinder. The discharge ports of the syringes are connected to respective discharge tubes which in turn lead to a Y-connector which has its common outlet port connected to a single tube leading to a patient for intravenous infusion of the respective substances. The seating recesses of the pump housing are of different sizes to accept different sized syringes. The drive mechanisms are operable and controllable separately, for operation at different rates of speed and to independently control rates of discharge of the contents of each of the syringes.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
