Method and apparatus for preparing a diluted medicinal substance

Abstract

Provided are a system and method for presenting information related to a drug dilution. A computer memory stores a drug database with a plurality of drug entries, each of which includes an identification and concentration of a drug stored in an originating container. A reader is operable to read a barcode associated with the drug identifier of the originating drug container and the concentration and / or dose and volume of the drug in the container. A user selects or enters a desired drug preparation that may include one or more preparations of the originating drug requested for administration to a patient. A computer processor interprets the concentrate signal, identifies the concentration of the originating drug based on content included in the drug database, and determines a recipe to be presented to the user for preparing the drug including any required dilutions.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 798,798, filed Mar. 15, 2013, which is incorporated in its entirety herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This application relates generally to a method and apparatus for preparing a drug or medicinal substance and, more specifically, to method and apparatus for selecting a specific preparation that may include reconstituting, diluting, measuring and mixing a drug or medicinal substance, and displaying preparation instructions and preparing a label including content related to the preparation and optionally encoding relevant preparation information as a machine-readable code.[0004]2. Description of Related Art[0005]It is common for drugs or other medicinal substances to require one or more preparation steps prior to being administered to patients at a healthcare facility.

AI Technical Summary

Benefits of technology

The patent text describes a system and method for preparing drugs by reconstituting, diluting, measuring, and mixing them. The system includes a computer memory with a drug database and a reader to read a barcode on the drug container. The system can identify the drug and its concentration based on the database. An input device allows the user to select or enter a desired drug preparation, which includes options for dilution. The computer processor determines a recipe for preparing the drug based on the concentration information and the desired dilution. The system also includes a computer-readable memory to store the drug database and a computer-readable code to label the final prepared drug with a computer-readable code. The label includes information about the dilution, the diluent used, and the total dose and volume of the desired dilution. The technical effect of this patent is to provide a system and method for preparing drugs with improved efficiency and accuracy.

Problems solved by technology

Drugs are typically expensive, and are often administered in many different doses and volumes at a given healthcare facility depending on the specific needs of each patient.

It is impractical to inventory, in a pharmacy, originating drug containers storing each of the different concentration variants that may be required.

However, the dilution procedure described above for preparing a dilution is complex and time consuming.

Additionally, the calculations of the drug volume and diluent volume to be combined to fulfill the prescription are prone to human error, thereby raising the possibility that a dilution with the improper dose and volume may be prepared.
