Abstract
A method for drawing a solution using a system is provided. The system includes a filter, a vacuum source, and an actuator. The filter has an input port, a first output port, a second output port, and a flow path defined in part by the input port and the second output port. The vacuum source is in fluid communication with the first output port and operative to apply a vacuum to the flow path. The actuator is operative to facilitate movement of the solution along the flow path.
Claims6
A method for drawing a solution, the method comprising:
- applying a vacuum to a first output port (22) of a filter (14);
- moving, via an actuator (18), the solution along a flow path (26) defined in part by an input port (20) of the filter and a second output port (24) of the filter;
- restricting flow of the solution from a downstream device (30) to the second output port via a one-way check valve (44);
- operating the actuator in conjunction with a flow exchanger (34) to selectively direct the solution from the downstream device to a sensor (32) for quality control checks before dispensing;
- wherein the flow exchanger comprises:
- a first port (66) in fluid communication with the one-way check valve;
- a second port (68) in fluid communication with and directly coupled to the downstream device;
- a third port (70) in fluid communication with a normally closed one-way check valve (46), wherein the normally closed one-way check valve is disposed between the sensor and the third port;
- and
- wherein the one-way check valve (44) is directly coupled to the second output port (24) and the first port (66).
