Systems and methods for managing pneumatic pathways in integrated multilayer wound dressings

Abstract

A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominalcontents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluidconduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 674,970, filed May 22, 2018, which is incorporated herein by reference in its entirety. Background technique [0003] The present disclosure relates generally to wound treatment systems, and more particularly to wound treatment systems configured to provide drip therapy and negative pressure wound therapy to fascial incisions in deep abdominal incisions. [0004] Instillation therapy is a type of wound treatment that involves the application of therapeutic fluids (such as saline solutions, prescription solutions, antibiotics, cleaning fluids, etc.) to the treatment site to promote wound healing and granulation growth, prevent wound drying, prevent wound A treatment site that has become infected with bacteria and / or treats an infection. Some instillation systems include an instillation fluid container and an infusion pump for providing...

Problems solved by technology

However, manual irrigation may result in damage requiring further surgical intervention

[0007] Drip and negative pressure systems adapted to treat open peritoneal cavities are often complex due to the need to maintain fluidly separated drip and NPWT pathways, and it can be difficult to identify fluidly separated drip pathways in wound treatment systems deployed in patients and NPWT pathway

Additionally, wound therapy systems can expand and contract during cycles of instillation and NPWT, making it difficult to maintain a fluid-tight seal over the instillation and NPWT pathways

Additionally, a stiff drip connector and / or NPWT connector may contact the patient or otherwise cause patient discomfort during connection of the drip connector and / or NPWT connector or during compression that occurs during NPWT
