Infusion site interfaces and insertion devices for infusion site interfaces

摘要

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.

主权项

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; 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; and wherein a spring element that in a first configuration is not functional and in a second configuration actuates the needle cover toward the second position, wherein the spring element irreversibly changes from its first configuration to its second configuration when the needle cover arrives at the second position for the first time.
