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.

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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. 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; (iii) the medicament interface substantially perpendicular to the skin surface when the infusion-site frame member is adhesively attached to the skin surface; and
,(iv) 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 releasably couple both to the pump-body frame member and to the hub, the infusion-pump body comprising; a medicament reservoir to contain a medicament; an 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 releasing of the infusion-pump body from the hub, and the fluid path is re-established upon recoupling of the infusion-pump body to the body-pump interface, wherein the hub-engagement member is in continuous fluid communication with the medicament reservoir, and wherein the fluid path passes through only a single septum. - View Dependent Claims (12, 13, 14, 15, 16)
