Abstract
In some embodiments, a tube portion can be configured to be fluidically coupled to a patient access component. A source of pressurized fluid can be coupled to the tube portion and can be configured to deliver fluid to the tube portion at a source pressure. A fluid pressure regulating device can include an expandable reservoir and can be coupled to the tube portion such that the expandable reservoir is in fluidic communication with the tube portion. The fluid pressure regulating device can be configured such that, when fluid is delivered from the source of pressurized fluid to the lumen of the tube portion at the source pressure, the expandable reservoir of the fluid pressure regulating device can receive fluid such that the expandable reservoir of the fluid pressure regulating device expands and fluid is delivered from the lumen of the tube portion to the patient via the patient access component.
