Abstract
Modular intravenous (IV) assemblies are provided. The modular IV assembly includes a drip chamber having a body and an inlet connector, a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port and a flow control assembly coupled directly to a first portion of the base housing. Any of a filter assembly, an anti-run dry member, a check valve and an air vent assembly may be included in the modular IV assembly. IV sets and methods of use are also provided.
Claims20
A modular intravenous (IV) assembly, comprising:
- a drip chamber having a body and an inlet connector;
- a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port, wherein the flow path cavity comprises a first flow area having a constant width and a varying depth, and a second flow area having a varying width and a constant depth;
- and
- a flow control assembly coupled directly to a first portion of the base housing, the flow control assembly comprising;
- a roller housing;
- a roller;
- and
- a flow control membrane disposed between the roller and the flow path cavity in the base housing.
An intravenous (IV) set, comprising:
- a modular IV assembly, the modular IV assembly comprising:
- a drip chamber having a body and an inlet connector;
- a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port;
- a flow control assembly coupled directly to a first portion of the base housing, the flow control assembly comprising;
- a roller housing;
- a roller;
- and
- a flow control membrane disposed between the roller and the flow path cavity in the base housing;
- a filter housing coupled directly to a second portion of the base housing;
- a fluid exit housing coupled directly to the filter housing;
- and
- a one-way check valve disposed between an exit cavity in an outer surface of the filter housing and the fluid exit housing, the check valve configured to allow fluid to flow out from the exit cavity through an exit port in the fluid exit housing while preventing fluid from flowing in an opposing direction into the exit cavity;
- a fluid container coupled to the inlet connector of the drip chamber by a first IV tube;
- and
- a fluid delivery member coupled to the modular IV assembly by a second IV tube.
A method of delivering a medical fluid, the method comprising:
- coupling a fluid container to a modular intravenous (IV) assembly with a first IV tube, the modular IV assembly including a drip chamber having a body and an inlet connector, a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port and a flow control assembly coupled directly to a first portion of the base housing, the flow control assembly including a roller housing, a roller and a flow control membrane disposed between the roller and the flow path cavity in the base housing, wherein the flow path cavity comprises a first flow area having a constant width and a varying depth, and a second flow area having a varying width and a constant depth;
- coupling a fluid delivery member to the modular IV assembly with a second IV tube;
- and
- adjusting a fluid flow rate from the modular IV assembly to the fluid delivery member by moving the roller in the flow control assembly.
