With the acceleration of the modern life pace, knee pain has become a common health problem plaguing people of all ages. According to statistics, the number of patients with knee joint diseases in China has exceeded 100 million, among which the pain caused by sports injuries, arthritis or chronic strain accounts for as high as 70%. Although traditional treatment methods such as drugs, physical therapy and surgery can relieve symptoms, they have problems such as slow effect, strong dependence or the risk of side effects. Nowadays, VU-COT01 Hot and cold compression therapy machine——a medical device that combines cold and hot therapy with intelligent compression technology is offering patients a brand-new solution. Its scientific principles and clinical effects have attracted widespread attention from the medical community.
Dual effects of cold and heat, precisely targeting the root cause of pain
The core innovation of the cold and hot compression therapy machine lies in simulating the "contrast therapy" of professional rehabilitation institutions. By programmatically alternating the output of low-temperature and high-temperature airflows, it achieves a cycle treatment of "cold compress for pain relief - hot compress for healing". During the hypothermia treatment stage, the equipment acts on the affected area at a temperature close to the freezing point (usually 5-15℃), reducing the accumulation of local metabolic waste by instantly constricting blood vessels and rapidly inhibiting the release of inflammatory factors, thereby alleviating acute swelling and tingling. This process has been clinically verified to reduce pain perception by more than 40%, and is particularly suitable for the golden 48-hour emergency treatment period after sports injuries.
When the treatment enters the hot compress mode, the device raises the temperature to 40-45℃, dilates blood vessels to accelerate blood circulation, and promotes collagen synthesis and tissue repair. In combination with intermittent pulse compression technology, the device can act like an "intelligent masseur" to promote the return of lymph fluid and further remove metabolic waste. Li Wei, director of the Sports Medicine Center of a top-tier hospital in Beijing, said, "The 'vasomotor effect' caused by alternating hot and cold can activate cell metabolism. Compared with single temperature treatment, the rehabilitation efficiency is nearly three times higher."
Intelligent compression breaks through the limitations of traditional therapies
Traditional ice packs are prone to temperature loss due to melting, while hot packs pose a risk of scalding. However, the cold and hot compression treatment machine monitors the skin temperature in real time through sensors, keeping the error within ±0.5℃. Its dynamic compression function is a major breakthrough - the built-in airbag module of the device can simulate the techniques of professional physiotherapists and apply gradient pressure to the knee joint at a frequency of 30 to 60 times per minute. This "pressure wave" can not only prevent excessive accumulation of body fluids, but also activate proprioceptors through mechanical stimulation, helping to restore joint stability.
Despite the significant advantages of cold and hot compression technology, medical experts still emphasize the importance of standardized operation. Professor Zhang Minghua from the Rehabilitation Department of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine reminds: "During the acute injury stage, the principle of 'cold first, then hot' should be strictly followed. Each cold compress should not exceed 20 minutes, with an interval of at least one hour." Patients with chronic pain need to adjust the treatment cycle under the guidance of a doctor. In addition, the device is not suitable for people with open wounds, severe thrombosis, and sensory disorders.
With the intensification of population aging and the improvement of awareness of exercise and health, cold and hot compression treatment machines are moving from medical institutions to home Settings. According to industry reports, the global market size of rehabilitation medical devices is expected to exceed 38 billion US dollars by 2027, among which the compound annual growth rate of intelligent temperature control equipment is projected to reach 22%. This technology-driven rehabilitation revolution may redefine the future landscape of pain management.
