<p>The invention concerns an insertion device for inserting a medical device or a part of medical device into the subcutaneous or intramuscular area of a patient. Insertion devices (also called inserter or injector) are commonly used in the medical field for inserting medical devices, such as infusion sets, sensors and the like, through the skin of a patient in a more or less automated fashion. The present application relates to an insertion device comprising - a penetrating member (50) comprising an inserter part provided with holding means (52) and transformation means (51), and a subcutaneous part comprising at least one part such as a cannula or a sensor for subcutaneous positioning in a patient, - a moving part (38) comprising guiding means (39) which guiding means (39) restrict the movement of the transformation means (52) and guide the moving part (38) in a second direction which is normally linear and different from the first direction i.e. the direction of insertion, towards the injection site, and - a stationary housing (30) comprising guiding means (32) which guiding means (32) restrict the movement of the moving part (38), wherein the moving part (38) comprises at least two guiding means (39a, 39b) completely separated from each other which guiding means during full insertion of at least part of the subcutaneous part of the penetrating member (50) each are in engagement with separate parts of the transformation means (51a, 51b) during at least part of the full insertion.</p> |
