Wearable injector with sterile adhesive patch
An adhesive patch for a drug delivery device with a bacteria impermeable sterility margin surrounding an edge surface of the adhesive patch is disclosed, as well as a drug delivery device fixed to such an adhesive patch and a method of assembling a drug delivery device with such an adhesive patch. In some arrangements, the sterility margin is attached to or integral with a lower liner on a lower surface of the adhesive patch. In other arrangements, the sterility margin is attached to or integral with an upper liner on an upper surface of the adhesive patch.
1. A drug delivery device comprising:
a housing having a bottom wall;
an adhesive patch adhered to the bottom wall and having an area contained within an outer perimeter, the area having an upper surface, a lower surface, and an edge surface at the outer perimeter between the upper surface and the lower surface;
a bacteria impermeable lower liner on the lower surface; and
a bacteria impermeable sterility margin surrounding and abutting the edge surface of the adhesive patch,
wherein the outer perimeter of the adhesive patch is pre-cut to separate from the sterility margin.
2. The drug delivery device of claim 1 , wherein the bacteria impermeable sterility margin is attached to or integral with the adhesive patch or the lower liner.
3. The drug delivery device of claim 1 , further comprising a bacteria impermeable upper liner on the upper surface, wherein the sterility margin is optionally attached to or integral with the upper liner.
4. The drug delivery device of claim 1 , wherein the outer perimeter of the adhesive patch is pre-cut in a perforated manner to separate from the sterility margin.
5. The drug delivery device of claim 1 , wherein the housing includes an interior space and a top wall, a container is disposed within the interior space, and the top wall includes a window positioned to allow viewing of the container, the window including a polarized filter that filters out up to and including 50% of light in the visible range.
6. An adhesive system for use with a wearable drug delivery device, the system comprising:
an adhesive patch having an outer perimeter, an upper surface, a lower surface, and an edge surface at the outer perimeter and extending between the upper surface and the lower surface;
a bacteria impermeable lower liner on the lower surface; and
a bacteria impermeable sterility margin surrounding and abutting the edge surface of the adhesive patch,
wherein the outer perimeter of the adhesive patch is pre-cut to separate from the sterility margin.
7. The adhesive system of claim 6 , wherein the bacteria impermeable sterility margin is attached to or integral with the adhesive patch or the lower liner.
8. The adhesive system of claim 6 , further comprising a bacteria impermeable upper liner on the upper surface, wherein the sterility margin is optionally attached to or integral with the upper liner.
9. The adhesive system of claim 8 , wherein the upper liner includes a pre-cut first perimeter surrounding a portion of an area of the adhesive patch that is configured to be adhered to a drug delivery device.
10. The adhesive system of claim 6 , further comprising a hole provided in the area to allow passage of a delivery member of the drug delivery device.
11. The adhesive system of claim 6 , wherein the outer perimeter is pre-cut in a perforated manner to separate from the sterility margin.
12. The adhesive system of claim 6 , wherein the sterility margin has a width of at least two millimeters.
