[0036] An embodiment of the present application provides a portable arthritis treatment device.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, a portable arthritis therapeutic device includes a shell 1 and a strap 11. The shell 1 is used to cover the surface of the knee. The strap 11 is connected to both sides of the shell 1 and is used to fix the shell 1 on the knee joint. An electric heating pad 2, a pulse electric generator 3, conductive massage beads 4 and a medicine drainage mechanism are fixed in the shell 1.

[0038] The shape of the electric heating pad 2 matches the shape of the inner wall of the shell 1 and is used to wrap the knee surface.

[0039] The conductive massage beads 4 are provided in plurality, and the plurality of conductive massage beads 4 are surrounded around the knee. The conductive massage beads 4 are rotatably installed in a shell 1, and a driving component 42 for driving the conductive massage beads 4 to rotate is provided in the shell 1. The electric heating pad 2 is provided with a through hole 21 for exposing the conductive massage beads 4.

[0040] The pulse electric generator 3 is installed in the shell 1, and the plurality of conductive massage beads 4 are electrically connected to the output end of the pulse electric generator 3. The pulse current generated by the pulse electric generator 3 is transmitted to the skin surface at the knee position through the massage beads.

[0041] The medicine drainage mechanism is connected to the medicine injection chamber 12 arranged outside the shell 1. The medicine drainage mechanism is used to drain the medicine in the medicine injection chamber 12 to the surface of the conductive massage beads 4, and apply the medicine to the skin at the knee position through the conductive massage beads 4.

[0042] The electric heating pad 2 of the present application can be used for hot compress on the knee, and the rotating conductive massage beads 4 can be used to massage the knee joint. During the hot compress process, the medicine can be applied to the joint skin through the medicine drainage mechanism and the rotation of the massage beads, thus realizing the process of applying medicine and hot compressing at the same time; at the same time, the present application also transmits pulse electricity to the location of medicine application through the conductive massage beads 4 through the pulse electric generator 3. The stimulation of the skin by pulse electricity greatly shortens the stagnation time of drug delivery to the skin, so that the medicine reaches the deep tissue directly to achieve the purpose of target treatment. The present application performs massage, hot compress and pulse electric stimulation while applying medicine to the treatment part, thereby accelerating the absorption of medicine by the treatment part and improving the treatment effect.

[0043] In one embodiment, the conductive massage beads 4 are metal massage beads, specifically stainless steel massage beads.

[0044] like Figure 2 , Figure 3 and Figure 5As shown, a mounting plate 5 is provided between the inner wall of the shell 1 and the electric heating pad 2, the mounting plate 5 and the shell 1 match in shape, the pulse electric generator 3 is mounted on the mounting plate 5, and conductive shafts 41 are fixed at both ends of the conductive massage beads 4. The conductive shaft 41 is mounted on the mounting plate 5 through an insulating bracket 43, and the conductive shaft 41 and the insulating bracket 43 are rotatably connected. The output end of the pulse electric generator 3 is in sliding contact with the conductive shaft 41 through a wire, and the conductive shaft 41 is located on the side of the electric heating pad 2 away from the knee, and the output shaft of the drive component 42 and the conductive shaft 41 are fixedly connected through an insulating member.

[0045] The present application specifically defines the installation of the conductive massage beads 4, so that the axis of the conductive massage beads 4 is located on the back of the electric heating pad 2, and a small portion of the conductive massage beads 4 is exposed from the electric heating pad 2, so as to avoid the need to open a large hole on the electric heating pad 2 due to the shaft of the conductive massage beads 4 being exposed, which affects the actual heating area of ​​the electric heating pad 2. The drive component 42 may be a motor.

[0046] The length direction of the conductive shaft 41 is arranged in the horizontal direction, and the conductive massage beads 4 and the through hole 21 are arranged at intervals. The length direction of the conductive shaft 41 is arranged in the horizontal direction to reduce the medicine flowing along the conductive massage beads 4 to the conductive shaft 41, reduce the medicine flowing to the drive component 42, reduce the corrosion and damage to the drive component 42, ensure the stable operation of the therapeutic device, and there is a gap between the conductive massage beads 4 and the inner wall of the through hole 21 to prevent the medicine on the conductive massage beads 4 from sticking to the electric heating pad 2. It should be noted that when the user uses the joint therapeutic device in a sitting position, keep the thigh flat and the calf vertical, wear the shell 1 correctly on the knee, and use the shell 1 in this state as a reference during the assembly of the conductive massage beads 4, so that the length direction of all conductive shafts 41 is arranged in the horizontal direction.

[0047] like Figure 7 As shown, the medicine injection cavity 12 is located on the outer surface of the housing 1 near the thigh side, and the medicine drainage mechanism includes a main delivery hose 6 and a plurality of branch hoses 61. The main delivery hose 6 is connected to the medicine injection cavity 12, and one end of the branch hose 61 is connected to the main delivery hose 6. The other end of the branch hose 61 extends above the conductive massage beads 4, and the end surface of the branch hose 61 contacts the surface of the conductive massage beads 4. In the implementation of this application, when the user wears the therapeutic device correctly, the position of the medicine injection cavity 12 is higher than all the conductive massage beads 4, and the medicine drips from the medicine injection cavity 12 through the main delivery hose 6 and the plurality of branch hoses 61 under the action of gravity, and falls on the surface of the conductive massage beads 4.

[0048] like Figure 4 and Figure 6The insulating bracket 43 is provided with a fixing plate 51 on one side close to the mounting plate 5, and the fixing plate 51 is mounted on the mounting plate 5 via a spring 52, and the driving assembly 42 is mounted on the fixing plate 51. The setting of the spring 52 allows the conductive massage beads 4 to be retractable and flexible, and the retraction of the spring 52 allows the conductive massage beads 4 to adjust their positions adaptively according to the knee joint shapes of different users, and the springs 52 corresponding to the conductive massage beads 4 closer to the skin are subjected to greater pressure, and the springs 52 corresponding to the conductive massage beads 4 slightly farther from the skin are subjected to less pressure, so that each conductive massage bead 4 can contact the skin, thereby avoiding the situation in which some conductive massage beads 4 contact the skin, but some conductive massage beads 4 do not contact the skin during use.

[0049] like Figure 3 and Figure 4 As shown, in one embodiment, for the installation of the conductive massage beads 4 and the driving assembly 42, grooves for accommodating the conductive massage beads 4, the driving assembly 42, the fixing plate 51 and the spring 52 are provided on the side of the mounting plate 5 facing the electric heating pad 2, and the position around the groove on the side of the mounting plate 5 facing the electric heating pad 2 is in contact with the electric heating pad 2 to provide support for the electric heating pad 2.

[0050] The surface of the conductive massage beads 4 is provided with a plurality of protrusions. In the first aspect, the protrusions can be used to periodically provide different massage strengths, and can also expand the surface area of ​​the conductive massage beads 4, increase the amount of medicine attached to the conductive massage beads 4, and prevent the medicine from dripping from the conductive massage beads 4 onto the electric heating pad 2 or other parts, thereby reducing the waste of medicine and avoiding damage to other parts of the therapeutic device. The protrusions are not shown in the figure.

[0051] The electric heating pad 2 described in the present application includes a flexible pad body and a silicone electric heating wire. The flexible pad body is hollow and filled with a heat-conducting fluid medium. The silicone electric heating wire is distributed in the cavity inside the flexible pad body and directly contacts the heat-conducting fluid medium. The flexible pad body includes a first flexible pad and a second flexible pad. The first flexible pad and the second flexible pad are provided with openings corresponding to the through holes 21. The edges of the first flexible pad and the second flexible pad and the edges of the openings are sealed and connected to form a hollow structure. Among them, the specific structure of the electric heating pad 2 is not shown in the figure. The outer peripheral edges of the first flexible pad and the second flexible pad are fitted together, and the edges of the opening positions are also fitted together.

[0052] The heat transfer fluid can be used to transfer heat to the skin more evenly, avoiding local high temperature causing discomfort to the user. The heat transfer fluid can be water, and the electric heating pad 2 is filled with a fluid medium, which has the ability to deform, and can change the shape of the electric heating pad 2 according to the shape of the user's knee, so that the electric heating pad 2 fits the skin better.

[0053] The edge and center of the electric heating pad 2 are connected to the mounting plate 5 by Velcro, and the power cable of the electric heating pad 2 and the power cable for powering the electric heating pad 2 are electrically connected by a quick-plug connector. The portable arthritis therapeutic device also includes a cold compress pad, the edge and center of the cold compress pad are connected to the mounting plate 5 by Velcro, and the position where the Velcro is set on the electric heating pad 2 is the same as the position where the Velcro is set on the cold compress pad. The Velcro and the cold compress pad are not shown in the figure.

[0054] Through the detachable electric heating pad 2 and the detachable cold compress pad, the user can replace the electric heating pad 2 or the cold compress pad for hot and cold compress according to the needs. In the embodiment of the present application, the cold compress pad needs to be placed in a refrigerator in advance to cool down. When cold compress is needed, the electric heating pad 2 is removed, and a low-temperature cold compress pad is installed, and then the therapeutic device is worn on the knee joint for cold compress. The cold compress pad matches the shape of the inner wall of the shell 1 and is used to wrap the surface of the knee.

[0055] like Figure 8 As shown, a lithium battery 7 is disposed in the housing 1 , and the lithium battery 7 is used to supply power to the electric heating pad 2 , the pulse electric generator 3 and the driving component 42 .

[0056] like Figure 1 As shown, the outer surface of the housing 1 is provided with a switch 13 for respectively controlling the power on and off of the electric heating pad 2, the pulse generator 3 and the drive assembly 42. The user selectively turns on or off the rotation of the electric heating pad 2, the pulse generator 3 and the conductive massage beads 4 according to needs.

[0057] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
