[0002] The cause of rheumatoid arthritis is not yet fully understood, but it is generally believed to be related to infection and autoimmunity. When various sources of infection repeatedly stimulate synovial cells, a rheumatoid factor is produced and discharged into the joint fluid, combining with the immunoglobulin G in the fluid to form an antigen-antibody complex with the participation of complement; when the complex is phagocytosed by multinuclear leukocytes, the leukocyte lysosomes rupture and release a variety of enzymes; rheumatoid arthritis can cause joint inflammation to continue to develop due to the above-mentioned autoimmune effects; according to the different sites of onset, it can be divided into peripheral type: the most common, mainly affecting the small joints of the hands and feet and the elbows and knees, with symptoms of joint pain, swelling, and spindle-shaped; laboratory tests show increased erythrocyte sedimentation rate, positive serum rheumatoid factor test, and sometimes positive antistreptococcal hemolysin test; central type: prone to sacroiliac joints, spine and hip joints, often with lower back pain, spinal stiffness, and X-ray examination shows that the spine is "bamboo-shaped"; osteitis type: often occurs in the calcaneus, navicular bone, etc., pain and swelling make walking difficult, and X-rays show bone hyperplasia in the affected areas; mixed type: symptoms of all the above types are combined.

[0003] Rheumatoid arthritis patients require warmth and protection. Because their immune systems are abnormal and susceptible to cold weather, keeping warm is crucial. Firstly, warmth helps relieve joint pain and stiffness. In cold weather, the body constricts blood vessels, slowing blood circulation and depriving the muscles and tissues around joints of oxygen, which exacerbates joint pain and stiffness. Existing joint protectors are difficult to use, making it difficult to change joint dressings and making them difficult for patients to use. Utility Model Content

[0012] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 5 It is given, including an L-shaped protective cover 1, an insulation cavity 2 is opened on the inner side of the protective cover 1, an arc-shaped leakage groove 3 is opened on the lower left end of the protective cover 1, and notches 4 are respectively opened on the upper left end of the protective cover 1 and the lower right end of the protective cover 1. The opposite sides of the two notches 4 are connected with the leakage groove 3 respectively. A zipper 5 is provided in the notch 4, and the front and rear side walls of the notch 4 can be connected by the zipper 5. The left side of the protective cover 1 is disassembled and connected with an arc-shaped blocking cover 6, and a cavity 7 is provided inside the blocking cover 6. The blocking cover 6 can block the leakage groove 3. A rectangular and elastic fixing cover 8 is fixed on the inside of the blocking cover 6, and a winding belt 9 is fixed on the upper and lower sides of the protective cover 1.

[0014] In order to facilitate the injection of hot water into the heat preservation chamber 2 , a connecting pipe 10 is fixed to the rear side of the upper end of the protective sleeve 1 , the upper end of the connecting pipe 10 is connected to the outside and the lower end is connected to the heat preservation chamber 2 .
