Description

Knee pad with percutaneous nerve electrical stimulation performance

Technical Field

The utility model relates to a knee-pad device field especially relates to a knee-pad with percutaneous nerve electricity stimulation performance.

Background

In sports and rehabilitation therapy, knee protection products are generally used to safely support and protect the knee joint, particularly for patients with knee osteoarthritis. Knee Osteoarthritis (KOA) is a disease in which cartilage degeneration in articular surfaces and reactive bone loss in subchondral bone plates occur due to local damage and inflammation and chronic strain of the knee joint, resulting in a series of symptoms and signs in the knee joint. The prevalence rate of knee osteoarthritis is related to the age, sex, ethnic group and geographical factors of patients, and modern medicine considers that osteoarthritis is the result of the comprehensive action of multiple factors, wherein the main factors include cartilage matrix synthesis and catabolism disorder, cartilage loss of buffer effect due to subchondral bone plate damage, intra-articular localized inflammation and the like. The prevalence rate of knee joint symptomatic osteoarthritis in China reaches 8.1%, and the prevalence rate of groups over 65 years old reaches 50.0%.

Chinese patent CN201521089985.6 describes a physiotherapy kneepad, wherein two sides of the kneepad body are respectively provided with a long strap symmetrical to the diagonal of the kneepad body, the two long straps can respectively bind the upper part and the lower part of the knee, and can be tightened in a segmented manner, and because the kneepad body is divided into two segments, the interference to the bending movement of the knee is small, the kneepad is compliant, the movement is convenient, and the supporting effect is good, however, the person skilled in the art finds in the actual operation: at present, the known knee pad products are mostly made of self-adhesive composite materials (commonly called diving materials), and are strip-shaped materials which can be bound and tightened around the knee. Except for the shape of some differences, the principle is basically the same, plays the effect of tightening, binding, fixing and supporting, has no other treatment functions, and when in use, needs external power supply, thus the moving range and the action amplitude of the user are limited by the length of the electric wire, the user is difficult to use in moving, the function of percutaneous nerve electric stimulation is reduced, and the health care treatment requirements of partial knee discomfort people can not be met. CN202021446493.9 discloses a heatable conductive pulse knee pad, which is provided with massage electrodes, and can stimulate related acupuncture points on the knee through the massage electrodes, so as to relieve the diseases of the knee part, and can supply power to an electric heating wire by inserting a power cord on a mobile power supply, and by this way, the heating effect of the electric heating wire can be achieved when the temperature is low, and the structure requiring the power cord is very inconvenient to move and carry, and the effect is not necessarily significant.

KOA pain relief is also clinically achieved using buried needles (TEA) and electric needles (EA) as a supplement and replacement therapy. The application of TEA and EA in combination with acupuncture stimulation and electrical stimulation is to embed a thread into the needle to enter the acupuncture point, and on the basis of the traditional acupuncture stimulation, the thread embedding generates continuous stimulation to relieve musculoskeletal pain. However, there is no definitive evidence that TEA and EA have improved KOA efficacy as evidenced by the presence or absence of acupuncture points. TEA and EA therapies do not have general applicability, and their disadvantages include: 1. the patient needs to be treated in a professional diagnosis and treatment institution by using special diagnosis and treatment equipment; 2. the technical requirements on the practitioners are high, and the selection and the depth of a proper acupuncture position and the selection of a proper electrical stimulation condition are required to be identified; 3. not all patients can adapt to the pain of acupuncture, and the safety of acupuncture is still under scrutiny. Other physical therapy methods such as massage, cold and hot compress and the like have no clear evidence for effectiveness; the above means are high in economic cost and inconvenient to use, the related methods are not unified, the individual tolerance of the patients is different, regular and effective health management cannot be completed, and sometimes even the condition of the patients is aggravated.

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive treatment method for stimulating nerves to relieve pain by inputting a specific low-frequency pulse current into a human body through the skin, and is also called as peripheral Nerve coarse fiber Electrical Stimulation therapy. TENS is different from TEA and EA, and is a non-invasive and effective adjuvant therapy means. TENS can affect the nerves of sensory afferent pathways by adjusting the stimulation intensity, frequency and time, and has analgesic effect. At present, TENS in basic research is mainly applied to relieving pain and has a good analgesic effect. Through retrieval, the prior art has not yet applied percutaneous nerve electrostimulation in the treatment of knee joint, and no device applying percutaneous nerve electrostimulation in the body surface nerve projection of knee joint has yet, and no structure that can produce weak and small electric current and store and discharge avoids often changing the battery or charging, and is very inconvenient to use. People do not want to pay attention to the electric quantity of a battery all the time when wearable equipment is used, meanwhile, a large number of wireless sensors used in the internet of things also need to be powered by the battery, the electric quantity needed by the equipment is small, for example, the wireless sensors need to work at the milliwatt level. Therefore, researchers begin to consider that various ambient energy sources, such as tiny vibrations, light, heat, electromagnetic waves and the like around people, can be collected and converted into electric energy to replace the essential batteries of the equipment, so that the system can run for a longer time without replacing the batteries, and a large amount of batteries can be saved for the equipment, thereby the system is more environment-friendly.
