INFUSION SITE INTERFACES AND INSERTION DEVICES FOR INFUSION SITE INTERFACES
First Claim
1. A device for inserting an infusion cannula and/or a sensor into a body of a patient, the device comprising:
- an insertion needle adapted to be removably arranged in the infusion cannula and/or sensor;
a handle structure connected to the insertion needle; and
a needle cover, wherein the needle cover is pivotably mounted on the handle structure and is rotatably movable between a first position, where a front part of the insertion needle is located in the needle cover, and a second position, where the front part of the insertion needle is exposed.

Abstract
A device for inserting an infusion cannula, or sensor, into a patient is presented. The device comprises an insertion needle removable within the infusion cannula, a handle connected to the insertion needle, and a needle cover. The needle cover pivotably mounted on the handle is rotatably movable between a first position, i.e., the front of the insertion needle is in the needle cover, and a second position, i.e., the front is exposed. An infusion site interface comprises a body mounted on a pad attached to the patient; an infusion cannula for inserting into the patient that is connected to the body; a cavity within the body fluidly connected to the cannula; and a septum that seals closed the cavity. The septum is penetrable by an insertion needle in the infusion cannula and by a hollow needle of an infusion tubing connector coupled to the infusion site interface.

16. An infusion site interface, the infusion site interface comprising:
-
an interface body mounted on a pad adhesively attached to a body of a patient; a soft infusion cannula inserted into the body of the patient, wherein the cannula is connected to the interface body; a cavity within the interface body fluidly connected to the cannula; and a septum that seals closed the cavity, wherein the septum is penetrable by an insertion needle in the infusion cannula, in a first angle (β

) to its perpendicular, and is penetrable by a hollow needle of an infusion tubing connector coupled to the infusion site interface, in a second angle (ε
) to its perpendicular;
wherein the infusion site interface comprises a guide to guide the hollow needle of the connector during coupling, parallel to a plane defined by the pad. - View Dependent Claims (17, 19, 20)
