Embodiment Construction

[0018] Embodiments of the present invention address issues related to fluid parameter measurement, in part, by providing an infusion system having a disposable portion and a reusable portion configured to communicate wirelessly with each other. In one aspect, the disposable part is configured without active electronics (power source) and is configured to receive operating energy wirelessly from the reusable part. In one aspect, the infusion sensor is disposed on the disposable portion.

[0019] figure 1 An infusion system 100 is shown in a particular configuration in accordance with the present invention. Disposable portion 102 includes fluid measurement system 200 and reusable portion 104 includes fluid monitoring system 256 . Disposable portion 102 and reusable portion 104 are communicatively coupled by wireless communication link 110 . Additionally, the disposable portion 102 and the reusable portion 104 are configured to be fluidly isolated from each other, thereby prev...

Abstract

A fluid delivery system includes a disposable portion and a non-disposable portion configured to communicate with each other wirelessly. The disposable portion includes electrical elements such as one or more sensors configured to be in sensing proximity of fluid, a processor, a memory and a transceiver. The transceiver is configured to receive radio frequency energy from a transmitter located on the non-disposable portion and power the electrical elements on the disposable portion. The non-disposable portion wirelessly controls the disposable portion during a fluid delivery session by programming operational parameters and monitoring fluid delivery measurements over the wireless communication link.

Description

technical field [0001] The present invention relates generally to infusion systems, and more particularly to an infusion system for wireless communication of sensor data. Background technique [0002] Intravenous (IV) infusion systems are used to infuse or withdraw fluids from a patient. Typical infusion systems include a disposable part attached to a non-disposable part. In operation, the fluid being delivered is usually in contact with the disposable part but isolated from the reusable part. The disposable portion is usually discarded after use due to sterility and contamination concerns. On the other hand, since the reusable portion is generally isolated from the fluid delivered through the system, the reusable portion can be reused over multiple infusion procedures. During an infusion operation, one or more sensors such as an air in line (AIL) sensor, a hydraulic pressure sensor, a liquid temperature sensor, etc. may be used to monitor infusion parameters.
