Drug delivery system including a drug-container holder and a pump assembly

摘要

A first drug delivery system includes first and second drug-container holders and first and second pump assemblies. The first (second) holder is adapted to receive a first (second) drug container having a first (a different second) dimensioned shape but not a second (first) drug container having a different second (a first) dimensioned shape. A second drug delivery system includes first and second bar code scanners, first and second drug-container holders, and first and second pump assemblies. The first (second) holder is adapted to receive a first (second) drug container having a dimensioned shape and to orient a positioned first (second) bar code of the first (second) drug container to face the first (second) bar code scanner because of the dimensioned shape. In one application, the first drug is a sedative drug, the second drug is an analgesic drug, and the drugs are used during a conscious sedation medical procedure.

主权项

1. A drug delivery system comprising:
a) a first bar code scanner; b) a first drug-container holder adapted to receive a first drug container having a first dimensioned shape and to orient a positioned first bar code of the first drug container to face the first bar code scanner because of the first dimensioned shape, wherein the first drug container contains a first drug, and wherein the first drug-container holder is adapted to access the first drug of the received first drug container; c) a second bar code scanner; d) a second drug-container holder adapted to receive a second drug container having a second dimensioned shape and to orient a positioned second bar code of the second drug container to face the second bar code scanner because of the second dimensioned shape that may be the same or different than the first dimensioned shape, wherein the second drug container contains a second drug, wherein the second drug-container holder is adapted to access the second drug of the received second drug container; e) a first pump assembly operatively connected to the first drug-container holder to access the first drug and adapted to deliver the first drug to a patient; and f) a second pump assembly operatively connected to the second drug-container holder to access the second drug and adapted to deliver the second drug to the patient, wherein the first drug container has a first central longitudinal axis and a rotationally-asymmetric, coaxially-aligned first perimeter surface portion, wherein the first dimensioned shape at least includes the first perimeter surface portion, and wherein the first drug container holder includes a rotationally-asymmetric first inner surface portion conformingly corresponding in shape to the first perimeter surface portion of the first dimensioned shape, the rotationally-asymmetric first inner surface portion linearly receiving the rotationally-asymmetric, coaxially-aligned first perimeter surface portion over final insertion of the first drug container into the first drug-container holder.
