Abstract
Embodiments of the present disclosure are directed to miniature insulin patch pump, assistance devices (e.g., for reservoir filling and/or cannula insertion), and methods related thereto. For example, in some embodiments, a substance/drug-delivery patch pump is provided and includes a reusable part (RP) including a power source, a driving mechanism, and an electronic module, and a disposable part (DP), where the disposable part can include at least a plurality of an adhesive base, a reservoir, a dosing mechanism, and a cannula.
Claims38
A patch pump assisting system comprising:
- an assisting device including a soft cannula insertion mechanism configured to at least insert a soft cannula in tissue, the device including:
- a housing;
- an first exit port septum configured within a cup opening;
- an exit port well;
- and
- an second exit port septum;
- and
- a soft cannula having a lumen, and a rigid cannula having a lumen,
- wherein:
- the soft cannula and rigid cannula each include at least one lateral opening along a length thereof;
- the housing is configured for placement on the skin of a user for cannula insertion;
- prior to insertion, the rigid cannula is positioned within the soft cannula with both cannulas initially traversing the cup septum, and the distal ends of the soft cannula and rigid cannula are positioned within the exit port well;
- immediately after insertion, the distal ends of the rigid cannula and soft cannula are positioned within and/or below the skin of a user, and corresponding lateral openings thereof are positioned within the well,
- and
- the rigid cannula is configured for removal from the soft cannula by retraction of the assistance device from the skin tissue of the user.
A method for inserting a soft cannula for a drug delivery system into the tissue of a user, comprising:
- triggering a trigger of a cannula insertion mechanism such that one or more safety catches release energy stored in an inserter spring of the inserter mechanism such that:
- an inserter hammer of the inserter mechanism is driven in a first direction,
- a cup, a cup opening, a cup septum, a rigid cannula and a soft cannula of the inserter mechanism move towards a patient's skin;
- and
- a tip of a rigid cannula punctures the skin establishing a path for a soft cannula;
- upon an end of the cup residing on an end of cup septum, the cup placed in the cup opening, and lateral openings of the rigid and the soft cannulas being in fluid communication with an exit port well, and corresponding ends of the rigid cannula and the soft cannula are under the patient's skin, the assisting device is removed while removing the rigid cannula from the lumen of the soft cannula.
