The invention provides a negative pressure wound treatment device which comprises a wound dressing, a liquid storage assembly and a driving assembly which are connected in sequence, and the driving assembly is configured to provide negative pressure for the wound dressing and the liquid storage assembly; wherein the liquid storage assembly can comprise at least one first acting piece, the first end of the first acting piece is communicated with the wound dressing, and the second end of the first acting piece is communicated with the driving assembly; and the at least one second acting piece is in fluid communication with the first acting piece, and the second acting piece is configured to store fluid flowing out of the wound dressing. Therefore, through the arrangement, effective conduction of negative pressure can be improved to a certain extent, and the wound healing effect can be improved.

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.

The invention relates to a diabetes medical instrument, and provides an intelligent negative pressure flushing closed-loop regulation and control system, which comprises a sensing module used for collecting physiological and environmental parameters reflecting the state of a wound surface in real time; the negative pressure module is used for applying controllable negative pressure to the wound surface; the flushing module is used for conveying a flushing medium to the wound surface; the control module is electrically connected with the sensing module, the negative pressure module and the flushing module and is configured to dynamically adjust negative pressure parameters and / or flushing strategies according to the parameters and trigger a response mechanism when an abnormal state is detected; the power supply and interaction module is used for providing power support and realizing man-machine information interaction; wherein the system is integrated in the same shell to form a wound surface treatment platform with an autonomous closed-loop regulation and control capability. The problems that an existing negative pressure wound therapy device is single in function, lagged in response, lack of active intervention ability and difficult to be suitable for families or grassroots scenes in diabetic foot ulcer treatment are solved.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein and a stabilizing structure that may aid in wound closure.
