Abstract
A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The flow regulator allows for the infusion pump to infuse at a rate that may be varied during use by the user. Additionally, the flow regulator is made from a material selected to operate under a wide range of pressures, from 5-40 PSI, making the flow regulator compatible with pressurized devices, such as, a non-electric pump.
Claims5
A flow rate control device configured for connection in a flow path between a non-electric infusion pump and a patient, the flow rate control device comprising:
- an inlet handle;
- an outlet handle;
- a fluid path disposed between said inlet handle and said outlet handle, said fluid path having manually adjustable dimensions;
- and said inlet handle and said outlet handle composed of materials that can withstand pressures of from 5 PSI-40 PSI.
