Multichannel coordinated infusion system
First Claim
1. An infusion system, comprising:
- a first delivery unit that delivers a first infusate to an infusion circuit;
a second delivery unit that delivers a second infusate to the infusion circuit;
a measurement device that determines an amount of undelivered first infusate remaining to be infused; and
a control system that;
controls delivery of the first infusate from the first delivery unit and delivery of the second infusate from the second delivery unit;
enables input of a predetermined volume of the first infusate to be delivered and input of a predetermined time period for infusion of the predetermined first insufate volume;
determines a time remaining in the predetermined infusion time period;
communicates with the first delivery unit, the second delivery unit, and the measurement device to determine an optimum first infusate infusion flow rate based on the predetermined first infusate volume, the predetermined infusion time period, the determined amount of undelivered first infusate remaining in the system and the determined time remaining in the predetermined infusion time period; and
controls the first delivery unit to deliver the first infusate at the determined optimum first infusate infusion flow rate.

Abstract
An infusion system comprises a first pump device that delivers a first infusate, preferably a medication, to an IV infusion line and a second pump device that delivers a second infusate, preferably a neutral carrying solution, to the IV line. The infusion system also includes a measurement device that determines an amount of undelivered first infusate remaining in a receptacle. Furthermore, the infusion system includes a control system that communicates with the first and second delivery devices and the measurement device to determine an optimum first infusate infusion flow rate based on the determined amount of undelivered first infusate remaining in the system, a predetermined volume of fluid to be infused, and a predetermined infusion time period, and for controlling the first delivery unit accordingly. The present invention also provides methods for infusing a medication into a patient.

16. An infusion system comprising:
-
a first delivery unit that delivers an infusion ultrafiltrate to a hemofilter;
a first measurement device that determines an amount of infusion ultrafiltrate in the infusion system;
a receiver unit that receives a patient'"'"'s removed ultrafiltrate from the hemofilter;
a second measurement device that determines an amount of removed ultrafiltrate in the infusion system;
a control system communicating with the delivery and receiver units and the first and second measurement units to determine optimum flow rates to and from the hemofilter, based upon the determined amounts of infusion ultrafiltrate and removed ultrafiltrate in the infusion system, and a predetermined desired pressure differential between the infusion and removed ultrafiltrates, and for controlling the delivery and receiver units accordingly. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A method of infusing a second infusate into a patient, comprising the steps of:
-
determining a total volume of first infusate is to be infused;
ascertaining a period over which the total volume of first infusate is to be infused;
detecting a remaining amount of first infusate to be infused;
calculating time remaining in the period;
delivering a second infusate into an infusion circuit;
infusing the first infusate into the infusion circuit; and
automatically adjusting the infusion based on the remaining amount of first infusate to be infused and the time remaining in the period. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
