Infusion site interfaces and insertion devices for infusion site interfaces

Abstract

A device (4) for inserting an infusion cannula (12) or a sensor into a body of a patient comprises an insertion needle (41) adapted to be removably arranged in the infusion cannula (12) or sensor, a handle structure (45) connected (451) to the insertion needle, and a needle cover (42). The needle cover (42) is pivotably mounted (424) on the handle structure (45), and is rotatably movable (51) between a first position, where a front part (413) of the insertion needle (413) is located in the needle cover (42), and a second position, where the front part of the insertion needle is exposed. An infusion site interface (1) comprises an interface body (16) mounted on a pad (15) adapted for being adhesively attached to a body of a patient; a soft infusion cannula (12) adapted for being inserted into the body of the patient, wherein the cannula (12) is connected to the interface body (16); a cavity (17) arranged within the interface body (16), fluidly connected to the cannula (12); and a single septum (13) that sealingly closes the cavity (17). The single septum (13) is adapted to be penetrable by an insertion needle (11) arranged in the infusion canula (12), and is adapted to be penetrable by a hollow needle (21) of an infusion tubing connector (21) coupled to the infusion site interface (1). The hollow needle is arranged in an angle ? to the infusion cannula.; The infusion site interface (1) comprises guiding means (14) that are adapted to guide said hollow needle (22) of the connector (21) during coupling parallel to a plane defined by the pad (15).

Description

technical field [0001] The present invention relates to injection point interfaces with flexible injection cannulas, and insertion devices for use with flexible injection cannulas, sensors, etc., and more particularly to injection point interfaces for use with syringe pump devices, for use with syringe pump devices Insertion device for injection point interface. Background technique [0002] Devices for the automatic release of liquid medicaments are typically used by patients who have a continuous but varying need for medication, which may be administered by subcutaneous injection. Specific applications are eg certain pain therapies and the management of diabetes. Syringe pump devices are particularly suitable for self-administration of liquid medicaments. In this case, a computer controlled syringe pump device is used which is carried by the patient and which contains a quantity of liquid medicament in a reservoir. The reservoir usually contains enough medicine for a si...
