Abstract

An infusate cassette is described for use with an IV infusion system which controls the process of administering a drug to a patient. The cassette and other aspects of the infusion system may include disposable components, external redundant volume tracking, air removal and automated purge and prime capabilities, component removal lockout mechanisms, and/or redundant automated anti-free flow devices. An IV manifold comprising an imbedded high cracking pressure anti-free flow valve is also described for use with the infusion system. The cassette, IV manifold, and other aspects of the infusion system may be provided with quality assurance mechanisms for use with integrated IV infusion.

Claims

1. A care system for alleviating patient pain, anxiety and discomfort associated with medical or surgical procedures said system comprising:

a patient health monitor device adapted so as to be coupled to a patient and generate a signal reflecting at least one physiological condition of the patient;

a drug conduit which carries a flow of the drugs from a drug container to the patient;

an infusion pump which effects the flow of drugs through the drug conduit;

a cassette removably interconnected to the infusion pump, wherein a portion of the drug conduit is placed adjacent to the cassette, such that the infusion pump operates in cooperation with the drug conduit to effect the flow of the drugs, and wherein the cassette is adapted to carry a drug container;

a drug delivery controller interconnected with the infusion pump that manages the delivery of one or more drugs from the drug container to the patient via the drug conduit;

a memory device storing a safety data set reflecting safe and undesirable parameters of at least one monitored patient physiological condition; and

an electronic controller interconnected between the patient health monitor, the drug delivery controller, and the memory device storing the safety data set;

wherein said electronic controller receives said signal and in response manages the application of the drugs in accord with the safety data set.

2. A cassette for use with an intravenous infusion apparatus including a pumping mechanism which administers an infusate to a patient, wherein said cassette is removably attachable to the intravenous infusion apparatus, and wherein said cassette comprises:

a drug container entry mechanism having an infusate flow lumen, wherein infusate may flow from the container and into the flow lumen;

a pressure plate against which the pumping mechanism may act;

a means for attaching an infusate delivery conduit to the infusate flow lumen such that infusate can flow from the flow lumen into the delivery conduit;

a means for holding the infusate delivery conduit against the pressure plate such that the conduit is acted upon by the pumping mechanism in order to generate a flow of infusate from the container, through the flow lumen, into the delivery conduit, and to the patient; and

an indexing means for aligning the cassette when the cassette is attached to the intravenous infusion apparatus in a manner that allows proper administration of infusate to the patient.

3. A method for administering infusate to a patient, said method comprising the steps of:

attaching an infusate delivery conduit to an infusate flow lumen of a cassette, and aligning the conduit against a rigid pressure plate of the cassette;

attaching the cassette to an intravenous infusion apparatus such that the pressure plate aligns with a pumping mechanism provided with the infusion apparatus;

attaching an infusate container to an infusate container entry mechanism provided with the cassette;

attaching the infusate delivery conduit to a delivery means that is attached to the patient;

purging the infusion flow lumen and the infusion delivery conduit;

initiating the pumping mechanism in order to generate a flow of infusate from the container, through the flow lumen, into the delivery conduit, and to the delivery means attached to the patient; and

modulating the operation of the pumping mechanism based on measured or inferred effects of the infusate on the patient.
