Infusion device having offset flow path
First Claim
Patent Images
1. An infusion device, comprising:
- a housing configured to be applied to tissue;
an infusion cannula extending downwardly away from the housing and capable of receiving an insertion needle;
a septum disposed in the housing;
a passageway under said septum and in fluid communication with said cannula and;
an infusion needle insertable through the septum, the infusion needle capable of penetrating the septum and entering said passageway thereby forming a flow path between the infusion needle and the infusion cannula and wherein the infusion cannula and the infusion needle are aligned on separate non identical axes with the insertion needle being substantially perpendicular to the tissue so that it needle is axially rotatable with respect to thereto.

16. A method of infusing fluid into a patient, comprising:
- positioning an infusion housing, having a passageway, against a patient'"'"'s skin, such that an infusion cannula extends downwardly away from the infusion housing penetrates the patient'"'"'s skin along a first axis, thereby providing a pathway for infusate into the patient; and
inserting an infusion needle into the housing along a second axis adjacent, making said infusion need rotatable along said second access, said second axis being not identical with said first axis; and
causing infusate to pass through said insertion needle, into said passageway and then into said infusion cannula. - View Dependent Claims (17)

18. An infusion device, comprising:
a housing;
a connecting hub rotatable on said housing;
stops configured to limit the rotation of the hub;
an infusion cannula extending downwardly away from the housing and capable of receiving an insertion needle;
a septum disposed in the housing;
a passageway under said septum and in fluid communication with said cannula and;
an infusion needle insertable through the rotatable hub and the septum, the infusion needle capable of penetrating the septum and entering said passageway thereby forming a flow path between the infusion needle and the infusion cannula and wherein the infusion cannula and the infusion needle are aligned on separate non identical generally axes and where the connecting hub is rotatable between said stops.
