摘要： A test model may include a chamber, a tissue simulation material, and a visual indicator. The chamber may include a base, a lid, and an interior volume defined between the base and the lid. The tissue simulation material may be disposed within the interior volume of the chamber. The tissue simulation material may include a first surface and a second surface. The tissue simulation material may be configured to deform when the second surface is exposed to a lower pressure than the first surface in the interior volume of the chamber. The visual indicator may be configured to provide a visual state change in response to deformation of the tissue simulation material.

摘要： A dressing for a negative wound pressure therapy system includes a patient interface layer, a first fastening layer, a second fastening layer, and an upper cover. The patient interface layer defines an opening. The first fastening layer is coupled to the patient interface layer. The second fastening layer is detachably coupled to the first fastening layer such that the second fastening layer can be separated from and reattached to the first fastening layer while still forming a substantially airtight seal with the first fastening layer. The upper cover is coupled to the second fastening layer and covers the opening.

摘要： A replaceable absorbent dressing system for a negative pressure wound therapy system includes a dressing and an absorbent pad. The dressing includes a perforated layer. The absorbent pad is detachably coupled to the dressing such that the absorbent pad can be separated from and reattached to the dressing while still forming a substantially airtight seal with the dressing. In at least one embodiment, the dressing further includes a foam material disposed on a skin facing side of the perforated layer.
