Abstract

A closed, gravity-fed burette for intravenous (IV) fluid delivery and flush system supporting multiple input combinations for simplicity and standardization. Able to handle both hazardous and non-hazardous drugs, this system may incorporate plastic and elastomeric materials that are resistant to the effects of antineoplastic materials in conjunction with a hazardous air filter module while still integration compatible with electronic peristaltic pumps for finer control of flow rate and when the IV infusion recipient's physical position is not compatible with a gravity-fed flow. The buoyant-activated shuttle valve enables the AutoStart function providing steady flush of the IV line to the patient for optimized vein patency from the Primary IV fluid feed. This Primary line works in conjunction with a Secondary IV fluid feed and a needleless connector Drug Port for multiple feed and flush conditions directed by way of a monoblock design supporting combinations of rotary, toggle, and check valves.

Claims17

Dependent claims

A gravity-fed burette system, comprising:

a hollow body providing a generally upright longitudinal axis which encloses a chamber to receive a liquid, wherein the chamber has a chamber outlet for delivering liquid from the chamber, a vent port from the chamber, a Primary IV bag inlet into the chamber, and a directed flow inlet into the chamber from a chamber valve;
a Primary IV bag inlet control valve operatively associated with the Primary IV bag inlet to restrict flow from the Primary IV bag inlet into the chamber;
a Primary IV bag branch into the chamber valve;
a Primary IV bag branch control valve operatively associated with the Primary IV bag branch to allow liquid to flow from the Primary IV bag branch through the chamber valve into the chamber;
a Secondary IV bag inlet into the chamber valve;
a Secondary IV bag inlet control valve operatively associated with the Secondary IV bag inlet to allow liquid to flow from the Secondary IV bag inlet through the chamber valve into the chamber;
and
a drug port inlet into the chamber valve;
wherein the chamber valve allows liquid to flow through the drug port inlet into the chamber in a first configuration and allows liquid to flow from the drug port inlet through the chamber valve into the Secondary IV bag inlet in a second configuration.

6 more elements

A gravity-fed burette system, comprising:

a primary IV bag;
a secondary IV bag:
a hollow body configured with a longitudinal slot providing a generally upright longitudinal axis which encloses a chamber to receive a liquid, wherein the chamber has a chamber outlet for delivering liquid from the chamber, a vent port from the chamber, a Primary IV bag inlet into the chamber, and a directed flow inlet into the chamber from a chamber valve;
a Primary IV bag inlet control valve operatively associated with the Primary IV bag inlet and the primary IV bag to restrict flow from the Primary IV bag inlet into the chamber;
a Primary IV bag branch into the chamber valve;
a Primary IV bag branch control valve operatively associated with the Primary IV bag branch to allow liquid to flow from the Primary IV bag branch through the chamber valve into the chamber;
a Secondary IV bag inlet into the chamber valve;
a Secondary IV bag inlet control valve operatively associated with the Secondary IV bag inlet and the secondary IV bag to allow liquid to flow from the Secondary IV bag inlet through the chamber valve into the chamber;
and
a drug port inlet into the chamber valve;
one or more first documentation labels bearing a first visual designation associated with the primary IV bag;
one or more second documentation labels bearing a second visual designation associated with the secondary IV bag;
and
one or more third documentation labels bearing a third visual designation associated with the drug port inlet;
wherein the chamber valve allows liquid to flow through the drug port inlet into the chamber in a first configuration and allows liquid to flow from the drug port inlet through the chamber valve into the Secondary IV bag inlet in a second configuration;
wherein each of the one or more first documentation labels, each of the one or more second documentation labels and each of the one or more third documentation labels are visually distinctive from one another;
and
wherein said one or more first, second and third labels are configured to be received by the longitudinal slot so as to provide a visual identification of the types and the priority of liquids infused through the gravity-fed burette system.
