1. A body-attachable medicament-dispensing system comprising:

  • an infusion-site interface to provide fluid communication between a medicament interface external to a patient'"'"'s body and a subcutaneous location on the patient'"'"'s body, the infusion site interface comprising;

    an infusion-site frame member configured to adhesively attach to a skin surface of the patient'"'"'s body at an infusion-site location; and

    ,a hub coupled to the infusion-site frame member, the hub comprising;

    (i) the medicament interface substantially perpendicular to the skin surface when the infusion-site frame member is adhesively attached to the skin surface; and

    ,(ii) a soft cannula to provide fluid communication between the medicament interface and a subcutaneous end of the soft cannula; and

    ,a pump-body frame member configured to adhesively attach to a skin surface of the patient'"'"'s body at a pump-body location adjacent to the infusion-site location; and

    ,an infusion-pump body configured to connect, detach and reconnect both to the pump-body frame member and to the hub, the infusion-pump body comprising;

    a medicament reservoir to contain a medicament;

    a hub engagement member configured to engage the medicament interface, wherein, when the hub engagement member engages the medicament interface, a fluid path is established from the medicament reservoir to the subcutaneous end of the cannula and traversing the medicament interface; and

    ,a medicament pump configured to pump medicament along the fluid path,wherein the fluid path is broken upon detaching of the infusion-pump body from the hub, and the fluid path is re-established upon reconnecting of the infusion-pump body to the body-pump interface,wherein the hub-engagement member is in continuous fluid communication with the medicament reservoir.
