Description

Technology Field

[0001] The present invention relates to a knee massager, and more specifically, to a knee massager that includes a massage body that tightly wraps around the knee area according to body shape, a massage means for pneumatic kneading massage, a heating means, an infrared emission means, and a controller capable of wired or wireless use, thereby improving comfort and stability without slipping down during use, making portability and use simple, enabling pneumatic massage, and simultaneously implementing a heating function, a near-infrared emission function, and a far-infrared emission function, thereby allowing one to feel a refreshing sensation from kneading the knee muscles, and simply implementing various complex therapeutic effects such as pain relief around the knee, muscle relaxation, improved blood circulation, enhanced immunity, inflammation relief, and waste removal. Background Technology

[0003] Generally, when muscle pain or arthritis occurs, pain is relieved by applying adhesive pain relievers in the form of patches, and in severe cases, treatment is performed at a hospital using heat therapy or low-frequency therapy devices. However, low-frequency therapy devices used in hospitals have complex structures and are expensive, so they could not be used in ordinary households.

[0004] Meanwhile, looking at the increasing prevalence of knee pain patients, representative diseases include degenerative arthritis, knee osteoarthritis, and patellar tendinitis. An analysis of the number of arthritis patients in Korea from 2006 to 2015 shows that the number has steadily increased from 4.38 million in 2006 to 6.11 million in 2015, meaning that approximately one in eight Koreans suffers from arthritis.

[0005] In particular, the number of arthritis patients in their 20s and 30s is increasing significantly, by 32% and 22% respectively, and among arthritis, the most common disease is analyzed to be osteoarthritis.

[0006] Once joint degeneration progresses, there is no way to completely stop it, so the best approach is to minimize pain when symptoms appear.

[0007] In addition, trauma from sports (hiking, long-distance walking, running, aerobics, soccer, tennis, etc.), increased obesity, excessive dieting, and repetitive stress are causes of the rising incidence of arthritis among modern people.

[0008] As of 2019, among the approximately 3 million patients with knee arthritis, women account for a high proportion of 70%, and while knee pain can occur in anyone, it is commonly mistaken for an age-related disease because it is typically attributed to degenerative arthritis.

[0009] However, the knee is an important part that supports the body weight, and pain can occur due to continuous joint use. In particular, Koreans tend to accelerate knee degeneration by frequently adopting postures that are bad for the knees, such as sitting cross-legged, kneeling, crossing legs, and sitting with knees together, due to their sitting culture.

[0010] In addition, myofascial pain syndrome can occur if the load on the knee is severe due to overweight or obesity, or if the muscles are strained due to a lack of activity recently. Myofascial pain syndrome is a representative cause of knee pain and is a major factor in the increase of young knee patients.

[0011] In addition, looking at the trend of patients with patellar tendinitis, the number increased by about 16% from 104,555 in 2015 to 121,765 in 2019, and the number of patients in their 20s and 30s is increasing at a high rate.

[0012] Therefore, the demand for home / personal combination medical devices is expanding for patients with knee pain who find it difficult to visit hospitals for treatment, and there is a need to apply small combination treatment modules to enable complex yet simplified treatment rather than individual unit treatments for knee pain.

[0013] However, conventional knee massage and treatment devices are not complex in function, such as heat, EMS, and vibration, and consist of simple EMS devices and heat devices, failing to satisfy the needs of patients requiring complex treatment. Consequently, due to the increase in patients with knee pain, there is a growing demand for knee pain treatment devices that are simple yet capable of complex treatment for personal / home use.

[0014] Furthermore, conventional devices for knee massage and treatment had the problem of being cumbersome and inconvenient to carry and use, such as requiring a separate switch box connected by wires.

[0015] In addition, conventional devices for knee massage and treatment had the problem of reduced comfort and stability because they would slip down from the knee due to vibrations during operation after being worn.

[0016] Therefore, there is a need for research and development on a knee massager that improves comfort and stability, allows for simple portability and use, enables pneumatic massage, and simultaneously implements heating, near-infrared, and far-infrared emission functions, thereby allowing the user to feel a refreshing sensation from kneading the knee muscles, as well as easily achieve various complex therapeutic effects such as pain relief, muscle relaxation, improved blood circulation, increased immunity, reduced inflammation, and elimination of waste products around the knee.
