Infusion Device Having Offset Flow Path
An infusion device, including: a housing; 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.
1 . An infusion device, comprising:
a housing;
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.
2 . The device of claim 1 , wherein the infusion cannula and the infusion needle are positioned parallel to one another.
3 . The device of claim 1 , wherein the infusion cannula and the infusion needle are positioned parallel to one another.
4 . The device of claim 1 , wherein the infusion cannula and the infusion needle are in different planes relative to each other.
5 . The device of claim 1 , wherein the infusion cannula and the infusion needle are at oblique angles relative to each other.
6 . The device of claim 1 , wherein the infusion needle is disposed in the center of the connecting hub and the infusion cannula is disposed off-center to the housing.
7 . The device of claim 1 , wherein the infusion cannula and the infusion needle have different diameters.
8 . The device of claim 1 , wherein the connecting hub is rotatable with respect to the housing.
9 . The device of claim 8 , wherein the connecting hub is rotatable 360 degrees with respect to the housing.
10 . The device of claim 8 , wherein the connecting hub is rotatable less than 360 degrees with respect to the housing.
11 . The device of claim 1 , wherein the connecting hub is attachable to the housing at different rotational positions.
12 . The device of claim 1 , wherein the connecting hub further comprises:
at least one flexible handle configured to attach the connecting hub onto the housing.
13 . The device of claim 1 , wherein the housing further comprises:
an adhesive bandage extending therefrom for holding the housing against the patient's skin.
14 . The device of claim 1 , wherein the connecting hub further comprises:
a fluid infusion tube extending from the connecting hub, the fluid infusion tube being in fluid communication with the infusion needle.
15 . The device of claim 1 , wherein the septum is pre-slit and wherein the infusion needle is a plastic tube.
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 an axis adjacent, but not identitical with said first axis; and
causing infusate to pass through said insertion needle, into said passageway and then into said infusion cannula
17 . The method of claim 16 , wherein the passageway in he infusion housing is a lateral passageway.
