Inserter device with horizontal moving part
First Claim
1. An insertion device comprising:
- a stationary housing that does not move relative to an insertion site during insertion,a penetrating member comprising an inserter part provided with a holding member and a transformation member, and a subcutaneous part comprising at least one part comprising a cannula or a sensor for subcutaneous positioning in a patient in a first direction of insertion forming an angle β
to the surface in which the penetrating member is to be inserted, wherein the angle β
is about 30°

a moving part that moves in a second direction from a first position to a second position relative to the insertion site during insertion comprising a guiding member restricting the movement of the transformation member, the moving part comprises at least two guiding members comprising at least two tracks formed in the moving part, wherein the at least two guiding members are completely separated from each other and the at least two tracks are formed in the moving part each having their separate starting point displaced relative to each other in the first direction of insertion and each of the at least two tracks having their separate ending point displaced relative to each other in the first direction of insertionwherein the stationary housing comprises a guiding member restricting the movement of the moving part and guiding the moving part in the second direction which is normally linear and different from the first direction towards an injection site,wherein the second direction of the moving part during insertion is essentially parallel to the surface in which the penetrating member is to be inserted and wherein the transformation member is unreleasably connected to the penetrating member in such a way that when the transformation member is moved or forced in a certain direction, the penetrating member is moved simultaneously with same speed and direction as the transformation member, and wherein the two tracks during full insertion of at least part of the subcutaneous part of the penetrating member each are in engagement with separate parts of the transformation member during at least part of the full insertion.

Abstract
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.
