Method and apparatus for preparing a medicinal substance
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.
1. A system for presenting information related to a drug dilution, the system comprising:
a non-transitory, computer-readable memory storing a drug database comprising a plurality of drug entries, each of the plurality of drug entries comprising: (i) a drug identification that identifies a drug stored in a drug container, (ii) a concentration of the drug stored in the drug container; and (iii) a plurality of pre-defined dilution options that are selectable by a user to specify a desired dilution of a concentrated drug to be labeled, the pre-defined dilution options comprising at least one of a first option having a pre-defined total dose and/or a pre-defined total volume different from a corresponding value on the drug container, and a second option that is selectable to generate a label for a custom dilution that is not pre-defined;
a reader that is operable to read a first computer-readable code associated with the concentrated drug to be diluted and transmit a concentrate signal;
an input device that presents the user with a user interface for entering the desired dilution of the concentrated drug requested for administration to a patient;
a computer processor adapted to interpret the concentrate signal and identify the concentrated drug based on content included in the drug database; and
a printer for printing label content onto a label to be applied to a delivery container for administering the desired dilution to the patient, wherein at least one of the plurality of pre-defined dilution options is designated in the drug database as a non-standard dilution and the printer generates a label indicating the label is for the non-standard dilution.
2. The system of claim 1 further comprising a printer for printing label content onto a label to be applied to a delivery container storing the desired dilution to be administered to the patient, wherein the computer processor is further adapted to transmit a print signal instructing the printer to print a second computer-readable code encoding information identifying the concentrated drug, a diluent used to dilute the concentrated drug, and a total dose and total volume of the desired dilution as label content onto the label.
3. The system of claim 1 , wherein the reader comprises a barcode reader.
4. The system of claim 1 , wherein each of the plurality of drug entries comprises a total dose and a total volume of the drug in the drug container.
5. The system of claim 1 , wherein the printer does not print the visible marking as part of the label content when another of the plurality of pre-defined dilutions, other than the non-standard dilution, is input as the desired dilution.
6. The system of claim 1 , wherein each of the plurality of drug entries further comprises at least one pre-defined diluent that is selectable by the user via the user interface as a diluent to be used to dilute the concentrated drug to the desired dilution.
7. The system of claim 1 , wherein the computer-readable memory stores, for each of the plurality of drug entries, a permission entry indicating whether dilution of the drug is permissible or required.
8. The system of claim 1 , wherein the computer processor is further adapted to determine whether the desired dilution input by the user exceeds the concentration of the concentrated drug to be diluted, and transmit a warning signal warning the user that the desired dilution of the concentrated drug can not be achieved.
9. The system of claim 1 , wherein the recipe comprises a volume of the concentrated drug and a volume of the diluent to be combined to achieve a total dose and total volume of the desired dilution.
10. A system for presenting information related to a drug dilution, the system comprising:
a non-transitory, computer-readable memory storing a drug database comprising a plurality of drug entries, each of the plurality of drug entries comprising: (i) a drug identification that identifies a drug stored in a drug container, (ii) a concentration of the drug stored in the drug container; and (iii) a plurality of pre-defined dilution options that are selectable by a user to enter a desired dilution of a concentrated drug to be labeled, the pre-defined dilution options comprising at least one of a first option having a pre-defined total dose and/or a pre-defined total volume different from a corresponding value on the drug container, and a second option that is selectable to generate a label for a custom dilution that is not pre-defined;
a reader that reads a first computer-readable code associated with the concentrated drug to be diluted and transmits a concentrate signal;
an input device that presents the user with a user interface for entering the desired dilution of the concentrated drug requested for administration to a patient;
a computer processor that is adapted to interpret the concentrate signal, identify the concentrated drug based on content included in the drug database and determine label content to be printed onto a label that is to be applied to a delivery container for administering the desired dilution to the patient, wherein the label content comprises a second computer-readable code encoding information identifying the desired dilution and a total dose and total volume of the desired dilution; and
a printer that prints label content onto a label for a delivery container for administering the desired dilution to the patient, wherein at least one of the plurality of pre-defined dilution options is designated in the drug database as a non-standard dilution and the printer generates a label indicating the label is for the non-standard dilution.
11. The system of claim 10 , wherein the printer does not print the visible marking as part of the label content when another of the plurality of pre-defined dilutions, other than the non-standard dilution, is input as the desired dilution.
12. The system of claim 10 , wherein the computer-readable memory stores, for each of the plurality of drug entries, at least one pre-defined diluent that is selectable by the user via the user interface as a diluent to be used to dilute the concentrated drug to the desired dilution.
13. The system of claim 10 , wherein the computer-readable memory stores, for each of the plurality of drug entries, a permission entry indicating whether dilution of the drug is permissible or required.
