Abstract
Devices and methods for wound treatment are disclosed. A chamber may define a treatment space having an interior engineered surface including a plurality of structures configured to provide pathways for the distribution of negative pressure and to exert mechanical stress on a wound. In some specific embodiments, the devices and methods may treat wounds on the head, neck, and face. One or more tubes may be in fluid communication with the treatment space to facilitate the application of negative pressure, the introduction of therapeutic agents, and the removal of wound material.
Claims20
A device for wound treatment, comprising:
- a chamber that includes an inner surface and a sealing portion that defines an isolated treatment space;
- a plurality of embossed structures arranged in a pattern on the inner surface of the chamber, the structures having a height of about 0.2 mm to about 5 mm and spaced about 0.2 mm to about 10 mm from one another, the structures configured to directly contact a wound and to create pathways for distributing negative pressure between the inner surface of the chamber and the wound;
- and
- at least one tube having a first end connected to the chamber, the at least one tube being in fluid communication with the isolated treatment space so as to enable at least one selected from the group of applying negative pressure to the isolated treatment space and applying a therapeutic agent to the wound.
A wound treatment device, comprising:
- a chamber configured to enclose a head and neck region of a patient, the chamber being made of an impermeable material that is sufficiently thin to conform to the head and neck of the patient, the chamber having a sealing portion at a base and an interior surface defining an isolated treatment space;
- a plurality of embossed structures on the interior surface of the chamber, the structures being configured to directly contact a wound and to create pathways for distributing negative pressure between the inner surface of the chamber and the wound;
- and
- at least one tube connected to the chamber and in fluid communication with the isolated treatment space so as to enable at least one selected from the group of applying negative pressure to the treatment space and applying a therapeutic agent to the wound.
The device of claim 17, wherein the plurality of the embossed structures are positioned in a uniform pattern on the inner surface.
