Drug delivery programming techniques
First Claim
1. A method comprising:
- obtaining, by one or more processors, one or more first fluid delivery parameters that at least partially define delivery of a first fluid within a downstream portion of a fluid path of a fluid delivery system, wherein a medical pump and a catheter of the fluid delivery system define at least a portion of the fluid path;
obtaining, by the one or more processors, one or more second fluid delivery parameters that at least partially define delivery of a second fluid within an upstream portion of the fluid path upstream from the first fluid, wherein the second fluid comprises a therapeutic agent;
determining, by the one or more processors and based on the one or more first fluid delivery parameters and the one or more second fluid delivery parameters, one or more third fluid delivery parameters that at least partially define delivery of a third fluid located between the first fluid and the second fluid in the fluid path, wherein the third fluid comprises a mixture of the first fluid and the second fluid, and wherein at least one of the one or more third fluid delivery parameters is different than the one or more first fluid delivery parameters and the second fluid delivery parameters; and
outputting, by the one or more processors, the one or more third fluid delivery parameters for controlling the medical pump to deliver the third fluid to a patient.

Abstract
Devices, systems, and techniques for programming drug delivery are described. Such techniques may account for diffusion and mixing of drug within the fluid or allow for more flexible programming options. In one example, a method may include determining one or more fluid delivery parameters (e.g., volume, flow rate, or period of time) for a fluid that is a mixture of two other fluids. The determination may be based on one or more fluid delivery parameters of the two other fluids and/or a concentration profile representing the mixing between the two other fluids. In other examples, drug delivery programming may be facilitated by the selection of various patterns and steps of drug delivery. The system may track volume of delivered fluid to maintain desired dosing of the patient.

24. A system comprising:
-
means for obtaining one or more first fluid delivery parameters that at least partially define delivery of a first fluid within a downstream portion of a fluid path of a fluid delivery system, wherein a medical pump and a catheter of the fluid delivery system define at least a portion of the fluid path; means for obtaining one or more second fluid delivery parameters that at least partially define delivery of a second fluid within an upstream portion of the fluid path upstream from the first fluid, wherein the second fluid comprises a therapeutic agent; means for determining, based on the one or more first fluid delivery parameters and the one or more second fluid delivery parameters, one or more third fluid delivery parameters that at least partially define delivery of a third fluid located between the first fluid and the second fluid in the fluid path, wherein the third fluid comprises a mixture of the first fluid and the second fluid, and wherein at least some of the one or more third fluid delivery parameters are different than the one or more first fluid delivery parameters and the second fluid delivery parameters; and means for outputting the one or more third fluid delivery parameters for controlling the medical pump to deliver the third fluid to a patient.
