Abstract
Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound dressing. The wound dressing can comprise an absorbent material, an electronics unit comprising a negative pressure source, the electronics unit integrated within the wound dressing and at least partially encapsulated by a flexible film. The electronics unit can include translucent or transparent components that allow light to travel through to reach adhesives or coatings on the electronic components that would otherwise be obscured.

A method of inspection of an electronics unit for use in a negative pressure wound dressing apparatus, the method comprising:
- applying a coating material to a portion of the electronics unit, wherein the coating material comprises a material that will fluoresce when exposed to UV light and the electronics unit comprises:
- a negative pressure source;
- an exhaust mechanism comprising a casing comprising an elongate portion comprising a first surface and an opposite second surface, wherein the first surface of the elongate portion is configured to extend at least partially across a surface of the negative pressure source;
- and
- a flexible circuit board, wherein the second surface of the elongate portion of the casing is configured to extend at least partially across a surface of the flexible circuit board;
- wherein the exhaust mechanism comprises a translucent or transparent material or a material that allows transmission of UV light;
- and
- wherein the coating material is positioned between the translucent or transparent material or the material that allows transmission of UV light and the flexible circuit board;
- and
- positioning the coated electronics unit under UV light to cause the coating material to fluoresce.
A method of manufacturing an electronics unit for use in a negative pressure wound dressing apparatus, comprising:
- providing an electronics unit, the electronics unit comprising:
- a negative pressure source;
- an exhaust mechanism comprising a casing comprising an elongate portion comprising a first surface and an opposite second surface, wherein the first surface of the elongate portion is configured to extend at least partially across a surface of the negative pressure source;
- and
- a flexible circuit board, wherein the second surface of the elongate portion of the casing is configured to extend at least partially across a surface of the flexible circuit board;
- wherein the exhaust mechanism comprises a translucent or transparent material or a material that allows transmission of UV light;
- applying an adhesive to the flexible circuit board to secure components of the electronics unit to the flexible circuit board, wherein the adhesive is configured to cure with exposure to light and the adhesive is positioned between the translucent or transparent material or the material that allows transmission of UV light of the exhaust mechanism and the flexible circuit board;
- and
- positioning the electronics unit under light to cause the adhesive to cure.
A negative pressure apparatus comprising:
- a negative pressure source;
- a casing comprising an elongate portion comprising a first surface and an opposite second surface, wherein the first surface of the elongate portion is configured to extend at least partially across a surface of the negative pressure source;
- and
- a flexible circuit board, the second surface of the elongate portion of the casing is configured to extend at least partially across a surface of the flexible circuit board;
- wherein the casing is configured to be positioned between the negative pressure source and the flexible circuit board;
- and
- wherein the casing is at least partially formed of a transparent or translucent material or a material that allows transmission of UV light, the transparent or translucent material or the material that allows transmission of UV light is configured to be positioned between the negative pressure source and the flexible circuit board.
