AI Technical Summary

Benefits of technology

The present invention is a cost-reduced ambulatory pump that allows for increased availability and acceptability of ambulatory infusion. The pump has a relatively short operating life due to low pump recovery rates. The safety of the pump is ensured by incorporating absolute operating life limits that prevent the pump from being used beyond its design life. The pump also provides an improved IV line clamp system reducing material costs. The invention features a look-ahead lockout of programming for the pump that prevents excessive use of the pump beyond its design operating life. The technical effects of this invention are reduced costs and improved safety and reliability of the ambulatory infusion pump.

Problems solved by technology

Pumps suitable for ambulatory use can have high total operating costs driven in part by the cost of the pump itself which must meet exacting medical standards while being compact, lightweight, and ruggedized for portable use.
Failure to recover the pump can occur when pumps are used in end-of-life treatment, or are damaged or lost in the field.
High operating costs associated with ambulatory pumps necessarily limit the availability of the use of such medical devices to some individuals even though the pump could greatly improve the quality of care.

Embodiment Construction

[0048]Referring now to FIG. 1, an ambulatory pump 10 may operate in conjunction with a medicament bag 12 communicating with an IV line 14. The medicament bag 12 may be, for example, a flexible plastic bag of the type used to hold IV solutions, and the IV line 14 provides a flexible tube allowing the flow of medicament from the medicament bag 12 and a patient connector 16 that may communicate with the patient through a needle or port or the like. The IV line 14 may include a bubble filter 17 for removing included air bubbles, limiting the need for air bubble sensing.

[0049]The ambulatory pump 10 provides a two-part housing having an upper electronics portion 18 that may attach to a lower clamp portion 20 to receive the IV line 14 therebetween along a longitudinal axis 22 being generally the longest dimension of the housing of the ambulatory pump 10. As so received, the ambulatory pump 10 may pump liquid through the IV line 14 by peristaltic action.

[0050]In one embodiment, the ambulato...

Abstract

A low-cost medical pump for ambulatory use provides reduced life components combined with a pump lockout enforcing a safe operating limit and preventing reuse after that limit is exceeded. An improved IV line clamp portion minimizes unsupported clamp structure length and provides a dual lock system preventing inadvertent clamp release.

Description

CROSS-REFERENCE TO RELATED APPLICATIONBackground of the Invention[0001]The present invention relates to compact infusion pumps for ambulatory use and in particular to an infusion pump design to reduce the costs of medical care delivery.[0002]Medical pumps, such as infusion pumps, are known for computer-controlled delivery of medication (henceforth medicaments) to patients over a period of time. Recently, battery-powered compact infusion pumps have become available that permit the patient to remain active (ambulatory), for example, in a home environment away from a clinic or hospital during the treatment.[0003]Typically the medicament is provided in a flexible bag that may be connected to an IV line which in turn attaches to a needle or port communicating with the patient. A nurse or other healthcare professional ministering to the patient receives the medicament, reviews the medicament description for correctness, and enters the desired dose and rate into the pump. The IV line is th...
