Embodiment Construction

[0194] Figures 1A to 1C An exemplary embodiment of a portion of the medical device 108 is shown in different perspective views. The medical device 108 also includes at least one patch, which will be further detailed by way of example in the following embodiments. The medical device 108 includes at least one pre-curved insertion sleeve 110 and at least one insertable element 112 . Figure 1A The pre-bent insertion cannula 110 in is shown in a flat shape, which is pre-bent, for example, due to an external force applied to the insertion cannula 110, as will be described in further detail below.

[0195] The insertion cannula 110 may particularly have an elongated shape. Furthermore, the insertion sleeve 110 can at least partially have a substantially rectangular shape, in particular a rectangular cross section. Specifically, the insertion sleeve 110 may be a slotted sleeve 114 . An end 116 of the insertion cannula 110 may include a slot 118 configured to facilitate insertion ...

Abstract

A medical device (108) for percutaneously inserting an insertable element (112) into body tissue (140) is disclosed. The medical device (108) comprises: at least one insertable element (112), wherein said insertable element (112) comprises at least one distal end (142) for subcutaneous insertion and at least one proximal end ( 144); · at least one insertion cannula (110) for subcutaneous insertion of said insertable element (112), said insertion cannula (110) having a wall fully or partially covered by said insertion cannula (110) (124) enclosing lumen (122), wherein said insertable element (112) is accommodated in lumen (122), wherein said insertion cannula (110) is a pre-bent insertion cannula (110) . The medical device (108) also includes at least one patch (172) configured to be mounted on the skin of the user (236). The patch (172) includes a patch base (174). Patch (172) includes an integrated insertion mechanism (182) for driving insertion cannula (110) from a stored position within patch (172) into an inserted position within body tissue (140) on a curved insertion path .

Description

technical field [0001] The present invention relates to a medical device for the percutaneous insertion of an insertable element into body tissue, an analyte measuring device for detecting at least one analyte in a body fluid, a device for delivering at least one drug to A medical device for a user and a method for percutaneously inserting an insertable element into body tissue. Devices and methods according to the present invention may primarily be used for long-term monitoring of analyte concentrations in bodily fluids, such as for long-term monitoring of blood glucose levels or one or more other types of analyte concentrations in bodily fluids. The invention can be applied both in the field of home care and in the field of professional care, such as in hospitals. Other applications are also possible. Background technique [0002] Monitoring certain bodily functions, and more specifically the concentration or concentrations of certain analytes, plays an important role in...
