主权项

1. An accommodating device capable of accommodating cartridges of different lengths from each other for a dispensing or infusion device, the device comprising:
a displaceable element comprising a detection element disposed thereon wherein the displaceable element is configured to be displaced within the accommodating device when one of the cartridges is inserted into the accommodating device; and at least one sensor configured to detect a position of the detection element based on the displacement of the displaceable element when the one of the cartridges is inserted into the accommodating device; wherein the at least one sensor is located at a fixed position with respect to the displaceable element which is a length-adjustable element, and the accommodating device is configured to determine the position of the length-adjustable element and determine the length of the one of the cartridges when fully inserted to detect the type of the inserted cartridge.
