Abstract
An injury treatment system includes a negative pressure source and a dressing pneumatically communicable with the negative pressure source. The dressing includes a negative pressure therapy component configured to expose an anatomical structure to a negative pressure when the negative pressure therapy component is applied to the anatomical structure and in response to operation of the negative pressure source. The dressing also includes an immobilization component coupled to the negative pressure therapy system, wherein the immobilization component is configured to transition from a flexible state to an inflexible state in response to the operation of the negative pressure source.
Claims14
An injury treatment system, comprising:
- a negative pressure source;
- and
- a dressing pneumatically communicable with the negative pressure source, the dressing comprising:
- a negative pressure therapy component configured to expose an anatomical structure to a negative pressure when the negative pressure therapy component is applied to the anatomical structure and in response to operation of the negative pressure source, and
- an immobilization component coupled to the negative pressure therapy component, wherein the immobilization component is configured to transition from a flexible state to an inflexible state in response to the operation of the negative pressure source.
An injury treatment device, comprising:
- a manifold layer having a patient-facing side and a non-patient-facing side;
- a first airtight chamber positioned along at least a portion of the non-patient-facing side of the manifold layer;
- locking sheets positioned in the first airtight chamber, the locking sheets configured to transition from a flexible state to an inflexible state;
- a sealable layer coupled to the manifold layer and configured to be sealed to a patient to define a second airtight chamber that contains the manifold layer;
- and
- a valve configured to selectively place the first airtight chamber in fluid communication with the second airtight chamber.
A method of treating an injury to a joint, comprising:
- applying a treatment device around the joint;
- sealing one or more edges of the treatment device to the joint to define a first airtight chamber containing a manifold layer;
- providing negative pressure therapy by pumping air out of the first airtight chamber to communicate a negative pressure to the joint;
- and
- providing immobilization therapy by pumping air out of a second airtight chamber, the second airtight chamber containing locking sheets configured to immobilize the joint in response to the second airtight chamber reaching at least a threshold negative pressure.
