Knee Electrical Stimulation Device

The present invention relates to a device for electric stimulation of the knee at a low frequency, and in more detail, it is easy to install and detach a pad that applies electric stimulation to the knee area according to the wearing area of the knee joint, and when power is applied, the electric stimulation is applied to the knee. The present invention relates to a knee electric stimulation device capable of increasing adhesion to the knee by a tube that is inflated when an applied pad is supplied with air.

In general, a joint means a place where the bones forming a skeleton are connected by two or more bones, and all movements of the human body are performed on the joint. Joints that perform these movements are also referred to as movable joints, and most skeletons of the human body are connected to these joints.

Among the various joints of the body, the knee joint, in particular, is a hinge-shaped joint that forms between the knee bones as the middle part of the leg. These knee joints are involved in extension and bending exercises.

In addition, the knee joint is an unstable joint in the structure of the bone, and tissues other than the joint such as muscles, ligaments, and articular membranes contribute to the stability of the knee joint.

However, damage to the cartilage protecting the knee joint or degenerative change may cause damage to the bones and ligaments constituting the joint, resulting in inflammation and pain.

This is called arthritis, and if these symptoms persist, deformity of the joint is caused. In particular, degenerative arthritis of the knee is the biggest cause of chronic physical disability.

Methods of treating fatigue, a disease that occurs in the knee joint including degenerative arthritis, include a combination of proper rest and exercise, administration of cartilage regeneration agents and pain relievers, injection of joint injections, use of anti-inflammatory drugs, marginal resection, osteotomy, joint Surgery using a mirror, total knee arthroplasty, etc. are mainly performed.

On the other hand, in recent years, by applying ultrasonic waves to the joints, the ultrasonic vibrations are transmitted to the cartilage cells in the cartilage tissue, which directly affects the activation of the cartilage cells. Known for this, various types of ultrasonic treatment devices have been developed.
