  • Patent number: 11951281
    Abstract: Disclosed herein are techniques related to insertion of a fluid conduit (e.g., tubing connected to a fluid reservoir or a cannula sharing a pre-assembled fluid pathway with such tubing). In some embodiments, an insertion mechanism may include one or more springs (e.g., a torsion spring or a compression spring). The one or more springs may cause a trocar or a trocar slider to pierce tissue and insert the fluid conduit. The one or more springs may further cause the trocar or the trocar slider to be removed from the tissue.

  • Publication number: 20240033493
    Abstract: A hydraulically actuated valve device includes a valve body having an inner cavity, an inlet channel extending to the inner cavity, an outlet channel extending from the inner cavity, and an open end that opens to the inner cavity. A septum is located in the inner cavity to seal the open end of the valve body and to receive a needle through which an operating fluid may be selectively injected into or withdrawn from the inner cavity to increase or reduce a fluid pressure in the inner cavity. A valve closing member has an unactuated state to enable a first fluid to flow from the inlet channel to the outlet channel when the fluid pressure of operating fluid in the inner cavity of the valve body is below a closing pressure, and inhibits the first fluid from flowing out of the inner cavity through the outlet channel when the operating fluid in the inner cavity of the valve body is at or above the closing pressure.

  • Publication number: 20230364336
    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.

  • Publication number: 20230233755
    Abstract: Integrated sensor and infusion devices are disclosed herein. The present technology includes, for example, an integrated sensor and infusion device for sensing physiological parameter(s) and delivering a medicament to a body of a user based at least in part on the sensed parameter(s). The device can comprise an insertion assembly comprising a carrier assembly comprising a cannula carrier, a trocar assembly removably coupled to the carrier assembly, and a drive assembly comprising a torsion spring coupled to the trocar assembly such that, when actuated, the torsion spring rotates to drive the trocar assembly and the carrier assembly axially downward to insert an infusion cannula and sensor electrode into a user's skin. The drive assembly can comprise a plurality of coupled drive wheels and/or a scissor assembly with multiple interacting links.

  • Publication number: 20220133993
    Abstract: According to an aspect, a cannula insertion mechanism includes a seal and a cannula carrier. The seal is configured to surround an opening of a housing, the seal including a first seal surface and a second seal surface, the first seal surface facing toward the opening, and the second seal surface facing away from the opening. The cannula carrier is configured to drive a cannula in a first direction through the opening of the housing, the cannula carrier having a first carrier surface and a second carrier surface, the first carrier surface being configured to exert a compression force on the second seal surface when the cannula carrier drives the cannula in the first direction, thereby causing the first seal surface to expand in a second direction to engage the second carrier surface via a clamping force.
