Abstract
A gravimetric verification system, method, and computer program product for automated detection and correction of reference density information based. An expected density of a fluid drug can be determined from the measured mass of a fluid drug and the intended volume of the fluid drug to be delivered to a medication container. The expected density can be compared to previously calculated densities for the fluid to verify the accuracy of a reference density value, verify the measurements and functional status of the measuring device for the fluid drug, and, in some instances, provide control or configuration commands to adjust one or more devices.
Claims22
A system comprising:
- a central repository system including one or more processors programmed and/or configured to:
- receive, from a gravimetric verification system, an identifier for a fluid, an intended volume of a first portion of the fluid to be delivered to a medication container, and a mass of the first portion of the fluid delivered to the medication container;
- determine an expected density of the first portion of the fluid based on the intended volume of the first portion of the fluid and the mass of the first portion of the fluid;
- determine a statistical parameter of a density of the fluid based at least in part on a relationship between the expected density and a set of densities of a plurality of portions of the fluid from respective gravimetric verification systems;
- and
- based at least in part on the statistical parameter, provide the expected density of the fluid to the gravimetric verification system.
A computer-implemented method comprising:
- receiving, with at least one processor, from a gravimetric verification system, an identifier for a fluid, an intended volume of a first portion of the fluid to be delivered to a medication container, and a mass of the first portion of the fluid delivered to the medication container;
- determining, with at least one processor, an expected density of the first portion of the fluid based on the intended volume of the first portion of the fluid and the mass of the first portion of the fluid;
- determining, with at least one processor, a statistical parameter of a density of the fluid based at least in part on a relationship between the expected density and a set of densities of a plurality of portions of the fluid from respective gravimetric verification systems;
- and
- based at least in part on the statistical parameter, providing, with at least one processor, the expected density of the fluid to the gravimetric verification system.
20-28. (canceled)
A computer program product comprising at least one non-transitory computer-readable medium including program instructions that, when executed by at least one processor, cause the at least one processor to:
- receive, from a gravimetric verification system, an identifier for a fluid, an intended volume of a first portion of the fluid to be delivered to a medication container, and a mass of the first portion of the fluid delivered to the medication container;
- determine an expected density of the first portion of the fluid based on the intended volume of the first portion of the fluid and the mass of the first portion of the fluid;
- determine a statistical parameter of a density of the fluid based at least in part on a relationship between the expected density and a set of densities of a plurality of portions of the fluid from respective gravimetric verification systems;
- and
- based at least in part on the statistical parameter, provide the expected density of the fluid to the gravimetric verification system.
