Abstract
Devices and methods for encapsulating a portion of a wound dressing with a coating are disclosed. In some embodiments, a method can comprise positioning a substantially flexible wound contact layer of the wound dressing on a perforated plate. The wound contact layer can include a first side supporting a plurality of electronic components protruding from a surface of the first side and a second side opposite the first side. The second side can be substantially smooth. The method can further comprise applying a vacuum to the wound contact layer through perforations in the perforated plate to hold the wound contact layer against the perforated plate and coating the wound contact layer with a coating.
Claims22
A method of coating a wound dressing, the method comprising:
- applying a vacuum to a substantially flexible wound contact layer to hold the wound contact layer on a perforated plate, wherein the vacuum is applied through one or more perforations in the perforated plate, the wound contact layer including a first side supporting a plurality of electronic components protruding from a surface of the first side and a second side opposite the first side, the second side being substantially smooth;
- and
- coating the wound contact layer with a coating.
A device for coating a wound dressing, the device comprising:
- a jig configured to support a substantially flexible wound contact layer of the wound dressing, the wound contact layer including a first side supporting a plurality of electronic components protruding from a surface of the first side and a second side opposite the first side, the second side being substantially smooth;
- a stencil configured to be positioned over the wound contact layer, the stencil comprising an opening configured to permit a biocompatible coating to be applied to at least one of the first or second sides of the wound contact layer positioned below the opening in the stencil, the stencil further comprising an unbroken surface adjacent to the opening and configured to prevent the biocompatible coating from being applied to at least one of the first or second sides of the wound contact layer positioned below the unbroken surface.
(canceled)
A method of coating a wound dressing, the method comprising:
- positioning a substantially flexible wound contact layer of the wound dressing on a jig, a first side of the wound contact layer supporting a plurality of electronic components protruding from a surface of the first side, a second side of the wound contact layer being positioned opposite the first side and being substantially smooth, the wound contact layer including a first registration mark, the positioning comprising aligning the first registration mark of the wound contact layer with a corresponding second registration mark on the jig;
- and
- causing coating to be applied to the wound contact layer.
