Embodiment Construction

[0038] overview

[0039]Referring generally to the drawings, a wound treatment system with fluid instillation and removal and components thereof are shown, according to various exemplary embodiments. The wound treatment system may include a treatment device and a wound dressing. The therapy device may include an infusion fluid tank, a removal fluid tank, valves, pneumatic pumps, infusion pumps, and a controller. Wound dressings may be applied to the skin surrounding a wound of a patient. The therapy device may be configured to deliver instillation fluid to the wound and provide negative pressure wound therapy (NPWT) by maintaining the wound at negative pressure. Components of the wound treatment device, the wound dressing and / or the wound form a negative pressure circuit.

[0040] The controller may estimate the volume of the wound based on the leak rate of the wound dressing and the amount of time it takes for the pneumatic pump to achieve the predetermined negative pres...

Abstract

A wound therapy system includes a negative pressure circuit, a pump, a pressure sensor, and a controller. The negative pressure circuit applies negative pressure to a wound. The pump is fluidly coupled to the negative pressure circuit and produces a negative pressure at the wound or within the negative pressure circuit. The pressure sensor measures the negative pressure within the negative pressure circuit or the wound. The controller performs a testing procedure including a first drawdown period, a leak rate determination period, a vent period, and a second drawdown period. The controller is configured to receive one or more pressure measurements of the pressure sensor over the leak rate determination period to determine a leak rate parameter, monitor an amount of elapsed time over the second drawdown period to determine a drawdown parameter, and estimate a volume of the wound based on the leak rate parameter and the drawdown parameter.

Description

Background technique [0001] The present disclosure relates generally to a wound treatment system, and more particularly to a wound treatment system configured to estimate a volume of a wound. [0002] Negative pressure wound therapy (NPWT) is a type of wound treatment that involves applying negative pressure to the treatment site to promote wound healing. Some wound management systems use pneumatic pumps to apply negative pressure to the wound to create the desired negative pressure and flow. Recent advances in the use of NPWT for wound healing involve the application of topical fluids to wounds to work in combination with NPWT. However, it can be difficult to determine the appropriate volume of instillation fluid to deliver to the wound. Additionally, it can be difficult to accurately monitor and track healing progress over time. Contents of the invention [0003] One embodiment of the present disclosure is a wound treatment system according to some embodiments. In some...
