Abstract
An indicator, wound dressing system, and negative pressure wound treatment kit configured to provide near real-time, dynamic indication of the fluid status (e.g., fill level, fluid absorbency capacity) of an article is described according to various embodiments. The indicator for detecting a fluid status of a wound dressing may include at least (i) a top side comprising PVDF and one or more markings configured to show fluid levels (ii) a bottom side comprising a pattern-printed adhesive, and (iii) a buffer layer, wherein the buffer layer has a top side comprising a polyurethane film and a bottom side comprising a film retention adhesive. Methods of using the indicator, wound dressing system, and kit are also provided herein.
Claims17
A wound dressing system, comprising:
- an uncrosslinked silicone polymer adhesive;
- and
- an indicator comprising a top side, a bottom side, and a buffer layer, wherein the top side comprises polyvinylidene difluoride (PVDF) and one or more markings configured to show fluid levels, the bottom side comprises a pattern-printed adhesive, and the buffer layer is positioned between the silicone polymer adhesive and the top side of the indicator, wherein the buffer layer further comprises a top side comprising a polyurethane film and a bottom side comprising a film retention adhesive.
A wound treatment kit, comprising:
- (i) a negative pressure source;
- (ii) a wound dressing configured to be attached to a patient, wherein the wound dressing comprises:
- (a) an uncrosslinked silicone polymer adhesive;
- and (b) an indicator comprising a top side, a bottom side, and a buffer layer, wherein the top side comprises polyvinylidene difluoride (PVDF) and one or more markings configured to show fluid levels along a lower surface thereof, the bottom side comprises a pattern-printed adhesive, and the buffer layer is positioned between the silicone polymer adhesive and the top side of the indicator layer, wherein the buffer layer further comprises a top side comprising a polyurethane film and a bottom side comprising a film retention adhesive;
- and
- (iii) a conduit configured to fluidly couple the negative pressure source to a treatment space defined underneath the wound dressing upon application of the wound dressing to the patient.
