Embodiment Construction

[0040] Figure 2A and 2B Examples of infusion pumps 10A and 10B (indicated more generally in this disclosure by the reference numeral 10 ), respectively, are shown which may be used to implement embodiments of the systems and methods discussed herein. In general, infusion pump 10A is a syringe-type pump that can be used to deliver a wide range of medications and treatments. The infusion pump 10A includes a drug container or syringe 12 respectively supported on a housing 14 and secured to the housing 14 by clamping means 16 . In an embodiment, the syringe 12 may be supplied separately from the pump 10A. In other embodiments, syringe 12 is an integral component of pump 10A. The syringe 12 includes a plunger 18 that forces fluid out of the syringe 12 via an infusion line 20 connected to the patient. A motor and screw arrangement inside housing 14 of pump 10A cooperates to actuate a pusher or plunger drive mechanism 22 to move plunger 18 . In an embodiment, the sensor (in i...

Abstract

An infusion pump includes a pumping mechanism having at least one sensor and a pump motor and a pump control subsystem configured to control operation of the pumping mechanism, the pump control subsystem including a processor, a memory, and a startup module configured to drive the pump motor at a first rate, receive input from the at least one sensor, and drive the pump motor at a second rate based on the input received from the at least one sensor. Startup algorithms command an infusion pump to reach a targeted delivery rate or steady state in minimal time without requiring priming of the pump line or otherwise engaging in known methods of pump startup analysis.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 61 / 938,264, filed February 11, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present subject matter relates generally to infusion pumps, and more particularly to priming algorithms for infusion pumps and related systems and methods. Background technique [0004] Infusion pumps are very useful medical devices for delivering prescribed fluids, drugs, and other treatments to patients. For example, drugs such as antibiotics, chemotherapy drugs, and pain relievers are often delivered to patients via infusion pumps as nutrients and other supplements. Infusion pumps have been used in hospitals, nursing homes, and other short- and long-term medical facilities, as well as in home care. Infusion pumps can be particularly useful for the delivery of medications that require administration over an extended period of time. There are many...
