Embodiment Construction

[0019] The disclosed matrix infusion cassette embodiments used in conjunction with IV pumps configured to actuate the matrix infusion cassette provide a wide range of flow rates with precise control of flow rates at the low end of the range. Certain embodiments of the matrix infusion cassette may be configured to provide independent control of multiple fluid flow rates.

[0020] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that embodiments of the invention may be practiced without some of the specific details. In other instances, well-known structures and techniques have not been shown in detail in order not to obscure the present invention.

[0021] 1A is a diagram of an exemplary embodiment of a patient 10 utilizing an infusion pump 12 to receive medical fluid from, in this example, a flexible bag 14 via a...

Abstract

A matrix infusion cassette for use with an intravenous (IV) pump is disclosed. The matrix infusion cassette includes a body configured to attach to the IV pump, the body having one or more inlet ports, an outlet port, and a plurality of pumping chambers, and a plurality of fluid conduits connecting the inlet ports to at least one pumping chamber, interconnecting the pumping chambers, and connecting at least one pumping chamber to the outlet port.

Description

technical field [0001] The present invention relates generally to the administration of medical fluids by infusion, and in particular to systems and methods for pumping infusion fluids. More narrowly, this document presents one embodiment of a matrix infusion pump and disposable assembly. Background technique [0002] Infusion pumps have become commonplace in the medical field as a means of precisely delivering intravenous (IV) fluids. Using a pump instead of a simple roller nip with a raised fluid container to control the flow of IV fluid allows for more precise and consistent control of the rate at which fluid is delivered to the patient. [0003] One of the challenges faced by infusion pump designers is to provide precise delivery at very low flow rates while maintaining a maximum flow volume sufficient to meet the needs of most patients. Positive displacement pumps are used to deliver fluid for hydration or nutrition and are capable of delivering up to 2 liters of flui...
