Intravenous solution producing systems and methods
First Claim
1. An injectable fluid preparation system comprising:
- an inlet configured to be coupled to a source of water;
a filtering device operable to at least partially purify water flowing from the source;
an additive supply in fluid communication with the filtering device, the supply supplying at least one additive to the at least partially purified water to form an additive solution;
at least one sensor having an output indicative of a proportion of the additive in water;
a housing supporting at least the filtering device and the sensor, the housing including a connector in fluid communication with the additive solution; and
a container connected fluidly to the connector, the container receiving an amount of the additive solution and configured to store the additive solution for later use.

Abstract
A portable system is provided in one embodiment that combines stages of water purification to produce sterile pyrogen free water for injection. It also adds NaCl to the purified water to produce sterile and pyrogen free saline for injection in a relatively compact and mobile delivery package. The solution produced is then bagged via suitable bagging equipment. Various methods are also provided to deareate the solution, ensure its stability and to disinfect the solution between uses and prior to use. The systems and methods in one embodiment produce on-line saline of less than 0 cfu and less than 0.03 EU/ml, while meeting acceptable levels of other chemical contaminants, heavy metals and organics.
