Medical device comprising a multipart housing

A method of using a medical device having an insertable element and a functional component that is connectable to the insertable element, the method comprising:

• connecting the insertable element to the functional component;
• connecting a protective component to the functional component and at least partially surrounding the functional component with the protective component;
• inserting the insertable element at least partially into the skin of a user at an insertion site;
• adhering the protective component directly to the skin surface and adhering the functional component directly to the skin surface of the user;
• providing a free space with the housing for access to the insertion site from above;
• and
• carrying out at least one medical function on the user with the medical device.

A medical device for carrying out at least one medical function, comprising:

• an insertable element that can be at least partially inserted into a body tissue of a user;
• and
• a housing adapted for placement on a skin surface of the user, the housing comprising:
• a functional component comprising an electronic module for the insertable element, the functional component being connectable to the insertable element;
• and
• a protective component configured to at least partially enclose the functional component, wherein the protective component is connectable to the functional component and wherein the functional component and the protective component each have a self-adhesive surface adapted to contact the skin surface;
• wherein, the functional component is operable for analysis of a body fluid when the functional component is disconnected from the protective component.
