Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dual-purpose treatment device for knee joint hot and cold compresses. Background Technology

[0002] A dual-purpose knee joint hot and cold compress therapy device is a medical device that combines the two treatment methods of hot and cold compress. By stimulating different temperatures, it aims to relieve knee pain, promote the dissipation of inflammation, and improve joint function. Currently, a common method is to use the device to cool or heat the circulating fluid in the water blanket tied to the knee, thereby achieving the effect of hot or cold compress.

[0003] Most existing water blankets are simply tied to the legs with elastic bands or other components. However, their effectiveness is limited. There is a need for a method that can stabilize the knee and leg, thereby appropriately restricting the range of motion of the knee joint during knee injuries or inflammation, preventing further damage or aggravation of inflammation, and preventing displacement of the treatment area due to movement or activity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that primarily involve binding water blankets to the legs with elastic bands or other components, resulting in limited effectiveness. This invention proposes a dual-purpose treatment device for knee joint hot and cold compresses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-purpose heat and cold compress therapy device for the knee joint, comprising a main body for both heat and cold compresses and a water blanket;

[0007] An external support frame is used to fix the water blanket to the knee. The external support frame includes a first semi-ring frame, a knee pad, and a second semi-ring frame. A first connecting frame is fixedly installed on both sides of the outer wall of the first semi-ring frame. A first circular plate is fixedly installed at one end of the first connecting frame. A second connecting frame is fixedly installed on both sides of the outer wall of the second semi-ring frame. A second circular plate is fixedly installed at one end of the second connecting frame. The second circular plate is rotatably mounted with the first circular plate on the same side. Side frames are fixedly installed on both sides of the outer wall of the knee pad. The other ends of the two side frames are respectively fixed to the outer walls of the two first circular plates. The water blanket is installed on the inner walls of the first semi-ring frame, the knee pad, and the second semi-ring frame.

[0008] In one possible design, the water blanket is provided with two connecting pipes, both of which are used to connect to the main body of the hot and cold compress device.

[0009] In one possible design, the outer support also includes a locking element for locking the first circular plate and the second circular plate. The locking element includes a threaded rod and a threaded cylinder. The threaded rod is fixedly disposed on one side of the first circular plate, and the second circular plate is rotatably sleeved on the outer wall of the threaded rod. The threaded cylinder is threadedly sleeved on the outer wall of the threaded rod, and one end of the threaded cylinder is engaged with the second circular plate.

[0010] In one possible design, the locking element further includes a slide cylinder that is slidably fitted onto the outer wall of the threaded cylinder. A polygonal block is fixedly provided on the inner wall of the slide cylinder, and a polygonal groove is provided at one end of the threaded rod, with the polygonal block cooperating with the polygonal groove.

[0011] In one possible design, a limiting strip is fixedly provided on the outer wall of the threaded cylinder, and a limiting groove is provided on the inner wall of the sliding cylinder, with the limiting strip slidably disposed inside the limiting groove.

[0012] In one possible design, a fixing ring is fixedly sleeved on the outer wall of the threaded cylinder, and a tension spring is sleeved on the outer wall of the threaded cylinder, with the two ends of the tension spring respectively fixedly disposed on one side of the fixing ring and one side of the slide cylinder.

[0013] In one possible design, elastic bands are provided at both ends of the first and second semi-ring frames.

[0014] In this application, during actual use, the external support is strapped to the leg with an elastic band, and the knee brace is positioned at the knee. Then, the main body of the hot and cold compress device is activated to cool or heat the internal circulating fluid, thereby applying cold or hot compresses through the water blanket strapped to the knee. During treatment, the patient can either fix the external support to ensure the water blanket is securely attached to the knee or release it to allow for movement. Specifically, the slide cylinder is moved outward, causing the polygonal block on the inner wall of the slide cylinder to disengage from the polygonal groove. The slide cylinder can then be rotated, causing the threaded cylinder to rotate, so that the end of the threaded cylinder abuts against or disengages from the side of the second circular plate, thus adjusting the effect. Afterward, the slide cylinder is reset by a tension spring, causing the polygonal block to re-lock into the polygonal groove, preventing the slide cylinder from rotating.

[0015] In this utility model, the knee joint hot and cold compress dual-purpose therapy device can achieve the effect of applying a water blanket to the knee joint through an external bracket, thereby enabling both hot and cold compresses.

[0016] In this utility model, the knee joint hot and cold compress dual-purpose treatment device can fix the external support through the locking component, so as to prevent the treatment area from shifting and the range of motion of the knee joint from being restricted due to movement or activity.

[0017] In this invention, the water blanket is tied to the knee with an external support during use, thereby achieving the effect of cold or hot compress by cooling or heating the circulating fluid. The external support can also be fixed as needed to allow for movement or reduce the range of motion of the knee. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-2A dual-purpose hot and cold compress therapy device for the knee joint includes: a main body 1 for hot and cold compresses, a water blanket 4, and an external support 2 for fixing the water blanket 4 to the knee. The main body 1 is an existing device, such as the Sanhong Medical Hot and Cold Compress Therapy Device. The external support 2 consists of a first semi-ring frame 3, a knee brace 5, and a second semi-ring frame 7. A first connecting frame 11 is fixedly installed on both sides of the outer wall of the first semi-ring frame 3, and a first circular plate 13 is fixedly connected to one end of the first connecting frame 11. Similarly, a second connecting frame 8 is fixedly installed on both sides of the outer wall of the second semi-ring frame 7, and a second circular plate 10 is fixedly connected to one end of the second connecting frame 8. The second circular plate 10 is rotatably connected to the first circular plate 13 on the same side, allowing the first semi-ring frame 3 and the second semi-ring frame 7 to rotate relative to each other, thereby enabling the external support 2 to bend according to the knee. Side frames 9 are fixedly installed on both sides of the outer wall of the knee brace 5, and the other ends of the two side frames 9 are fixedly connected to the outer walls of the two first circular plates 13. The water blanket 4 is installed on the inner walls of the first semi-circular frame 3, the knee brace 5 and the second semi-circular frame 7, and is used for hot or cold compress treatment of the knee.

[0026] Furthermore, the water blanket 4 is provided with two connecting pipes 6, both of which are used to connect to the main body 1 of the hot and cold compress equipment to achieve heating or cooling of the fluid inside the water blanket 4.

[0027] Example 2

[0028] refer to Figure 3-4 An improvement upon Embodiment 1 is made as follows: To lock the first circular plate 13 and the second circular plate 10, the outer support 2 further includes a locking component. The locking component includes a threaded rod 14 and a threaded cylinder 17. The threaded rod 14 is fixedly disposed on one side of the first circular plate 13, and the second circular plate 10 is rotatably sleeved on the outer wall of the threaded rod 14. The threaded cylinder 17 is threadedly sleeved on the outer wall of the threaded rod 14, and one end of the threaded cylinder 17 engages with the second circular plate 10. By rotating the threaded cylinder 17, one end abuts against the side of the circular plate, achieving fixation.

[0029] The locking component also includes a slide cylinder 18. The slide cylinder 18 is slidably sleeved on the outer wall of the threaded cylinder 17, and a polygonal block 19 is fixedly provided on the inner wall of the slide cylinder 18. A polygonal groove 21 is provided at one end of the threaded rod 14, and the polygonal block 19 cooperates with the polygonal groove 21.

[0030] To limit the axial movement of the slide cylinder 18, a limiting strip 16 is fixedly provided on the outer wall of the threaded cylinder 17, and a limiting groove 22 is formed on the inner wall of the slide cylinder 18, with the limiting strip 16 slidably disposed inside the limiting groove 22. In addition, a retaining ring 15 is fixedly sleeved on the outer wall of the threaded cylinder 17, and a tension spring 20 is also sleeved on the outer wall of the threaded cylinder 17, with both ends of the tension spring 20 fixedly disposed on one side of the retaining ring 15 and one side of the slide cylinder 18, respectively. The tension spring 20 ensures that the slide cylinder 18 automatically resets when no external force is applied, thus facilitating user operation.

[0031] Elastic bands 12 are provided at both ends of the first semi-ring frame 3 and the second semi-ring frame 7, and the outer support 2 is tied to the knees by the elastic bands 12.

[0032] Specifically, the outer support 2 is tied to the leg with elastic band 12, and the knee brace 5 is placed at the knee. Then, the main body 1 of the hot and cold compress device is activated to cool or heat the internal circulating fluid, thereby applying cold or hot compresses through the water blanket 4 tied to the knee. During treatment, the patient can fix the outer support 2 as needed to ensure that the water blanket 4 is firmly attached to the knee, or release the fixation to allow the patient to move freely. Specifically, the slide cylinder 18 is moved outward, causing the polygonal block 19 on the inner wall of the slide cylinder 18 to disengage from the interior of the polygonal groove 21. At this time, the slide cylinder 18 can be turned to drive the threaded cylinder 17 to rotate, so that the end of the threaded cylinder 17 abuts against or disengages from the side of the second circular plate 10, thereby adjusting the effect. Afterward, the slide cylinder 18 is reset by the tension spring 20, so that the polygonal block 19 is re-locked into the interior of the polygonal groove 21, thus preventing the slide cylinder 18 from rotating.

[0033] However, as is well known to those skilled in the art, the working principle and wiring method of the main body 1 of the hot and cold compress device are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
