Patent Images
1. A fluid delivery system comprising:
- a collapsible container including a bio-compatible fluid,a flow path leading from the container to a patient,a pressurizing assembly surrounding all or a portion of the container, anda pressurization assembly, where the pressurization assembly pressurizes the pressurizing assembly in a controlled manner resulting in a force exerted on the container and a fluid flow rate from the container through the flow path to the patient and where the pressurization assembly depressurizes the pressurizing assembly in either a rapid manner to rapidly reduce the force on the container and the fluid flow rate from the container or to reduce the force on the container and the fluid flow rate from the container in a controlled manner.

Abstract
Novel fluid delivery systems are disclosed to improve the delivery of bio-compatible fluids to a patient. The systems can include a housing having a bladder pressurized by a pressurization unit so that fluid flow rate can be controlled, changed and/or monitored. The systems can also include a scale and/or a flow control unit.

15. A fluid delivery system comprising:
-
a collapsible container including a bio-compatible fluid, a flow path leading to a patient, a pressurizing assembly surrounding all or a portion of the container, and a pressurization assembly includes an air pump, a tube connecting the pump to the pressurizing assembly, a pump control unit and a battery unit, where the pressurization assembly changes an internal pressure of the pressurizing assembly, where the pressurization assembly sets the force exerted on the container by increasing an internal pressure of the pressurizing assembly to a set point pressure, intermittently sets the internal pressure to at least one desired pressure, periodically, semi-continuously and/or continuously varies the pressure according to a pressure change protocol and where increasing or decreasing the pressure, increases or decreases the fluid flow rate, and a weighing assembly includes a connector for detachably connecting the pressurizing assembly to the weighing assembly and a weight measuring unit for measuring the weight of the pressurizing assembly, where the weighing assembly monitors and/or measures a volume of fluid delivered from the container to the patient and where the weighing assembly weighs the pressurizing assembly on an intermittent basis, periodic basis, semi-continuous basis, continuous basis or any combination of intermittent, periodic, semi-continuous, or continuous basis. - View Dependent Claims (16, 17, 18, 19, 20)
