DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0028] Figure 1 This is the first embodiment of the present invention, a rheumatic joint care device, including a tubular elastic band 1. In one embodiment, the aperture of the upper end of the elastic band 1 is larger than the aperture of the lower end, so that the elastic band 1 can adapt to the joints of the human leg and arm. The elastic band 1 is provided with an annular hot compress ring 2, and the hot compress ring 2 is made of elastic material, specifically rubber. A first hot compress cavity 3 is formed in the hot compress ring 2 and stores a liquid / gas medium. In this embodiment, the medium is specifically liquid to obtain better thermal conductivity. Hot compress strips 4 are formed on both sides of the elastic band 1 corresponding to the hot compress ring 2. The hot compress strips 4 extend along the length direction of the elastic band 1. The hot compress strips 4 are made of non-elastic material. A second hot compress cavity 5 is formed in the hot compress strip 4 and is connected to the first hot compress cavity 3. The medium elastically enters the second hot compress cavity 5 through the hot compress ring 2.

[0029] Preferably, a heating unit 6 is also included, which is connected to the first hot compress cavity 3 and is used to heat the medium in the hot compress ring 2.

[0030] During use, the medium can be preheated by the heating unit 6, and after the preheating is completed, the elastic band 1 is worn on the human body so that the heat compress ring 2 corresponds to the joint position of the human body, that is, the heat compress ring 2 is wrapped around the front end of the joint, and the heat compress strips 4 on both sides are respectively arranged on both sides of the joint, and the heating unit 6 continues to heat and maintain the medium at a constant temperature, thereby completing the heat therapy of the patient's joints. At the same time, during the patient's activities, the joints will naturally squeeze the heat compress strips 4, so that the medium in the second heat compress cavity 5 flows out into the first heat compress cavity 3 after squeezing, and after the joint is straightened again, the elasticity of the heat compress ring 2 drives the medium back to the second heat compress cavity 5, so as to complete the exchange of the medium in the second heat compress cavity 5, thereby maintaining the medium temperature in the second heat compress cavity 5 during long-term use.

[0031] Preferably, the heating unit 6 includes a control unit 7 and an arc-shaped electric heating plate 8, the electric heating plate 8 is arranged in the first hot compress cavity 3, and the control unit 7 is electrically connected to the electric heating plate 8 and is used to supply power to the electric heating plate 8.

[0032] Specifically, the number of the electric heating plates 8 is two and they are symmetrically arranged in the first hot compress cavity 3 .

[0033] Figure 2-6 This is the second embodiment of the present invention. It is different from the above embodiments in that, due to the heating method using the electric heating plate 8, when the joints are bent for a period of time due to the patient's posture, the distance between the electric heating plate 8 and the joints will be too close or even in contact due to the bending of the joints, causing discomfort or even the risk of burns caused by excessive temperature. Therefore, a protective layer 9 is provided on the inner side of the elastic band 1 corresponding to the hot compress ring 2, and a protective cavity 10 is formed in the protective layer 9. A squeezing bag 11 is provided on the side of the elastic band 1 away from the hot compress ring 2. The squeezing bag 11 is connected to the protective cavity 10. When the squeezing bag 11 is squeezed, the protective cavity 10 is propped up to isolate the human body from the hot compress ring 2.

[0034] During use, when the joint is bent, the extrusion bag 11 can be naturally squeezed, so that the protective cavity 10 can be slightly propped up, thereby isolating the hot compress circle 2 and the human body, thereby avoiding direct contact between the heating plate 8 and the human body, so as to achieve a protective effect and avoid the risk of burns. At the same time, after the joint is straightened again, the elastic force of the elastic band 1 is used to compress the protective cavity 10 to complete the re-collapse of the protective cavity 10 and the re-propping of the extrusion bag 11.

[0035] Preferably, the protective cavity 10 includes a connecting chamber 12 and a plurality of expanded chambers 13, and the plurality of expanded chambers 13 are evenly arranged along the circumference of the hot compress ring 2. The connecting chamber 12 is sleeved on the outside of the plurality of expanded chambers 13 and is connected with the outer ends of the plurality of expanded chambers 13 in sequence. The squeezing bag 11 is connected with the connecting chamber 12. Specifically, the squeezing bag 11 is connected with the connecting chamber 12 through a pipe built into the elastic band 1.

[0036] The provision of the connecting chamber 12 and the plurality of expansion chambers 13 can reduce the gas demand for expansion, so that the volume of the squeezing bag 11 is smaller, thereby further reducing the adverse effects of the squeezing bag 11 on joint movement.

[0037] Preferably, the elastic band 1 is provided with ventilation holes 14 on both the inner and outer sides corresponding to the hot compress ring 2 .

[0038] The provision of the air holes 14 can cooperate with the expansion and contraction of the protection cavity 10 to achieve gas circulation in the inner area of ​​the elastic band 1, thereby keeping the area dry and avoiding moisture, thereby improving the thermal therapy effect.

[0039] When the elastic band 1 is located at the knee position, the natural movement of the knee will cause the hot compress ring 2 to move downward during walking, thereby causing the hot compress ring 2 to be offset from the joint. Therefore, a traction component is provided at one end of the elastic band 1, and the traction component is connected to the elastic band 1 and provides traction. The traction component includes an elastic strip 15 and a restraint belt 16. One end of the restraint belt 16 is connected to the end of the elastic band 1, and the other end is fixed by Velcro. One end of the elastic strip 15 is connected to the restraint belt 16, and the other end is connected to the area of ​​the hot compress ring 2 corresponding to the elastic band 1.

[0040] The setting of the traction component can provide a traction effect to the hot compress ring 2 during the movement, thereby avoiding the position displacement of the hot compress ring 2 and ensuring stability during long-term wearing.

[0041] Preferably, anti-slip protrusions 17 are arranged on the inner side of the elastic band 1 .

[0042] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
