Abstract: Multistage vaporizers, such as for use in medical treatment systems, as well as related methods are described. In one example, a multistage vaporizer includes a first reservoir configured to hold a liquid and one or more pumping transducers positioned in the first reservoir. The multistage vaporizer also includes a second reservoir and one or more vaporizing transducers positioned in the second reservoir. The one or more pumping transducers positioned in the first reservoir are configured to generate and move droplets of a liquid in the first reservoir to the second reservoir, and the one or more vaporizing transducers positioned in the second reservoir are configured to create a vapor of the liquid in the second reservoir.

Abstract: A medical liquid filling system and associated methods are provided, the system comprising a disposable and a drive system. The disposable includes a tubular member and a piston slidably disposed within the tubular member for retraction and advancement within at least a first portion of the tubular member. The disposable may include a seal member for sealing the first portion of the tubular member and may be interconnected to the piston for co-movement therewith. The drive system may include a piston drive member selectively interconnectable to the piston for driven advancement and retraction of the piston within the tubular member. The drive system may be interconnected to a controller, which may be operable to automate or semi-automate various filling operations. A user interface may be interconnected to the controller for providing input of various system operation parameters, which may be communicated to the controller to facilitate automated or semi-automated operation of the filing system.
