Abstract
Keep vein open (KVO) infusion flow control devices are provided. The KVO infusion flow control device couples to intravenous (IV) tubing and includes a flow controller that provides a full open fluid flow rate through an outlet portion of the IV tubing when the flow controller is in an open position, and a KVO fluid flow rate through the outlet portion of the IV tubing when the flow controller is in a KVO position. Visual indicators are disposed on the KVO infusion flow control device.
Claims20
A keep vein open (KVO) infusion flow control device, comprising:
- an inlet tube connector comprising an intravenous (IV) inlet port, a first outlet port and a second outlet port;
- an outlet tube connector comprising an IV outlet port, a first inlet port, a second inlet port and a flow control orifice disposed within the second inlet port;
- a full flow tube coupled at one end to the first outlet port of the inlet tube connector and coupled at another end to the first inlet port of the outlet tube connector;
- a KVO flow tube coupled at one end to the second outlet port of the inlet tube connector and coupled at another end to the second inlet port of the outlet tube connector;
- and
- a single flow controller coupled to the full flow tube, the single flow controller by itself configured to control fluid flow through the full flow tube and an amount of fluid flow through the KVO flow tube,
- wherein the KVO flow tube is configured to always provide some fluid flow.
A keep vein open (KVO) infusion flow control device, comprising:
- a body comprising a full open orifice disposed through the body and a separate smaller KVO orifice disposed through the body at an angle to the full open orifice;
- a control member coupled to the body;
- and
- a visual indicator,
- wherein a first position of the control member is configured to engage the full open orifice with a fluid flow path to provide full fluid flow through an intravenous (IV) tube and a second position of the control member is configured to engage the KVO orifice with the fluid flow path to provide KVO fluid flow through the same IV tube.
A keep vein open (KVO) infusion flow control device, comprising:
- a body;
- a switch movably coupled to the body between a full open flow position and a separate KVO flow position;
- and
- a visual indicator,
- wherein a first position of the switch is configured to engage a full open orifice with a fluid flow path to provide full fluid flow through intravenous (IV) tubing and a second position of the switch is configured to engage a KVO orifice with the fluid flow path to provide KVO fluid flow through the same IV tubing, the KVO orifice being smaller than the full open orifice.
