1. A fluid delivery device comprising:
- a body having a body passageway, a top, a bottom surface, a first perimeter at the top, and a second perimeter close to the bottom surface, the first perimeter being positioned in a first plane that is perpendicular to an axis that is parallel to a portion of the body passageway, the second perimeter being positioned in a second plane that is parallel to the first plane, and the second perimeter being greater than the first perimeter, the body lacking a substantially-rectangular skin-contacting wing extending at an acute angle from an adjacent upstream body portion;
a cannula having a cannula passageway and a portion extending from the bottom surface;
a needle guide having a portion positioned within the cannula passageway and a tapered portion having a length; and
a septum having a portion in contact with the tapered portion of the needle guide for at least half of the length;
the fluid delivery device being configured to adhere to a living being'"'"'s skin.

4. A fluid delivery device comprising:
-
a body having a body passageway and an outer perimeter; a cannula having a cannula passageway and a portion extending from the body, the cannula being positioned such that any portion of the cannula that is outside a living being'"'"'s skin when the fluid delivery device is used is positioned within the outer perimeter of the body; a needle guide having a portion positioned within the cannula passageway and a tapered portion having a length; and a septum having a septum bottom surface and a portion in contact with the tapered portion of the needle guide for at least half of the length, the septum also having a greatest width and a greatest length, the greatest width being larger than the greatest length; the fluid delivery device being configured such that an injection needle that has passed through the septum to deliver medication to a living being during use of the fluid delivery device either (a) exits the septum into an open space that is within the body passageway and downstream of at least a portion of the septum bottom surface, or (b) contacts a portion of the fluid delivery device that is tapered inwardly.

5. A fluid delivery device comprising:
-
a body having a body passageway; a cannula having a portion extending from the body, a cannula passageway, and an upper tapered portion; a needle guide having a needle guide passageway and a tapered portion in contact with the upper tapered portion of the cannula; and a septum having a septum bottom surface and a portion positioned within the needle guide passageway; the fluid delivery device being configured such that an injection needle that has passed through the septum to deliver medication to a living being during use of the fluid delivery device either (a) exits the septum into an open space that is within the body passageway and downstream of at least a portion of the septum bottom surface, or (b) contacts a portion of the fluid delivery device that is tapered inwardly.

6. A fluid delivery device comprising:
-
a body having a body passageway and an outer perimeter; a cannula having a cannula passageway and a portion extending from the body, the cannula being positioned such that any portion of the cannula that is outside a living being'"'"'s skin when the fluid delivery device is used is positioned within the outer perimeter of the body, the cannula having a tapered portion; a needle guide having a portion positioned within the cannula passageway and a tapered portion having length, the tapered portion of the needle guide being in contact with the tapered portion of the cannula; and a septum having a septum bottom surface and a portion in contact with the tapered portion of the needle guide for at least half of the length; the septum bottom surface being configured and the septum being positioned such that if an injection needle that has passed through the septum to deliver medication to a living being during use of the fluid delivery device exits the septum bottom surface into an open space, the open space is within the body passageway and downstream of at least a portion of the septum bottom surface.
