Abstract
A device in accordance with an embodiment of the present technology includes a port through which the device receives and dispenses infusion liquid (e.g., insulin solution) and a container that holds the infusion liquid. The device also includes a hub at a flowpath extending between the port and the container. The hub defines a first passage and a second passage in parallel with one another. The device further includes a conditioner and a check valve at the first and second passages, respectively. The conditioner conditions liquid moving between the container and the port by passing the liquid through an adsorbent filter and a mechanical filter. The check valve causes liquid moving between the port and the container to move preferentially via the first passage when flowing in one direction and to move preferentially via the second passage when flowing in an opposite direction.
