Abstract
The present disclosure relates to a functional joint assist apparatus including an air bladder having a cut hole and divided into a plurality of air cells so that air is injected into at least one of the air cells; and a fixing unit coupled to a front surface or a rear surface of the air bladder to attach or detach the air bladder to/from the joint.
Claims12
A functional joint assist apparatus disposed inside a joint assister for assisting the joint assister, comprising:
- an air bladder comprising:
- a front surface;
- a rear surface;
- a cut hole passing through a thickness of the air bladder from the front surface to the rear surface, and
- a plurality of air cells partitioned so that air does not communicate between the air cells, wherein air is injected into at least one of the plurality of air cells, the plurality of air cells comprising:
- a first air cell formed at an upper side based on the cut hole and configured to surround and compress an upper side of a user's joint;
- a second air cell formed at a lower side based on the cut hole and configured to surround and compress at least a portion of a lower side of the user's joint;
- and
- a third air cell formed at a lower side based on the cut hole and configured to surround and compress at least a portion of the lower side of the patient's joint different from the portion that the second air cell is configured to surround and compress,
- wherein at least one air cell is divided into a left portion and a right portion,
- wherein a flow path connects the left portion and the right portion;
- and
- a fixing unit coupled to either the front surface or the rear surface of the air bladder for attaching the air bladder to the joint.

- a first air cell formed at an upper side based on the cut hole and having a first air injection hole;
- a second air cell formed at a lower side based on the cut hole and having a second air injection hole and formed narrower than a width of a lower side of the first air cell;
- and
- a third air cell formed at a lower side based on the cut hole and having a third air injection hole and extending outward from both side surfaces of the second air cell and located at the rear of the joint when surrounding the joint of a user,
- wherein the second air cell compresses a front side of the joint of the user when air is injected therein,
- wherein both side surfaces of the third air cell compresses a rear side of the joint of the user when air is injected therein,
- wherein at least one air cell is divided into a left portion and a right portion,
- wherein a flow path connects the left portion and the right portion;
- and
- a fixing unit coupled to a front surface or a rear surface of the air bladder for attaching the air bladder to the joint.
