Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a sealing device and a physiotherapy system. Background Art

[0002] Ozone has strong oxidizing property. When it encounters tissue fluid, plasma, lymph fluid, or urine, the following reaction will occur immediately: O 3 + biological macromolecule → O 2 + O. A single oxygen atom has strong activity and has extremely strong killing effects on pathogenic microorganisms such as bacteria, fungi, and viruses. In recent years, due to frequent mutation and enhanced drug resistance of pathogenic bacteria, although new anti-inflammatory drugs have been continuously introduced and the dosage of antibiotics has doubled, the treatment effect is not ideal; secondly, the number of cases of mixed infection with multiple pathogenic bacteria is increasing day by day. Facing a wide variety of antibiotics, attending doctors often have difficulty in choosing. Even when using combined medication, the treatment effect is mostly not ideal. Ozone has the characteristics of no damage to the liver and kidneys, no drug resistance, few allergic reactions, no need for drug sensitivity tests, non-toxic, harmless, and pollution-free, which has incomparable superiority compared with the irreversible pollution consequences caused by using chemical drugs to the environment.

[0003] However, the leg diameters of different users are different, and the current physiotherapy system cannot well adapt to the legs of different users. For the convenience of use, the current physiotherapy system generally directly places the user's leg into the box body of the physiotherapy system. When the seal between the user's leg and the box body is insufficient, it is easy to cause ozone emission and pollution. Summary of the Invention

[0004] The purpose of the present invention is to provide a sealing device, aiming to solve the problems of how to make the sealing device adapt to legs of different diameters and improve the sealing performance of the sealing device.

[0005] The present invention provides a sealing device for sealing a human leg, and the sealing device includes:

[0006] A housing structure, including a box body having a physiotherapy cavity and an end cover with an accommodation cavity formed therein. The physiotherapy cavity has an opening, and the end cover seals the opening.

[0010] In one embodiment, the cover plate is rotatably connected to the cover body, and a damping strip is convexly provided on the plate surface of the cover plate that abuts against the airbag ring. The cover plate rotates a predetermined angle relative to the cover body to drive the airbag ring to tighten around the human leg.

[0011] In one embodiment, fixing holes are formed at the edge of the cover body, threaded holes are formed at the positions of the box body corresponding to the fixing holes, and the housing structure further includes positioning bolts. One end of the positioning bolts passes through the fixing holes and is locked to the threaded holes.

[0012] In one embodiment, the sealing device further includes a footrest disposed in the physiotherapy cavity and used for supporting the human leg.

[0029] Please refer to Figures 1 to 3 , an embodiment of the present invention provides a sealing device 100, which can cooperate with a disinfection gas to disinfect and physiotherapize the human leg. Optionally, the gas is ozone. In this embodiment, ozone physiotherapy is performed on the human leg 42. In other embodiments, ozone physiotherapy can also be performed on the human palm or other parts. The sealing device 100 includes a housing structure 10 and a sealing structure 50. The housing structure 10 includes a box body 12 and an end cover 11. Optionally, both the box body 12 and the end cover 11 are made of hard materials, and the box body 12 has a physiotherapy cavity 121, and the physiotherapy cavity 121 has an opening 122. The material of the box body 12 can be a plastic material with a certain hardness or a metal material. The plastic material can be PVC material and is formed by an injection molding process. The end cover 11 is covered at the opening 122 and is hermetically connected to the box body 12 through a sealing ring. An accommodation cavity 111 is formed inside the end cover 11, and a through hole 15 communicating with the physiotherapy cavity 121 and for the human leg 42 to extend into the physiotherapy cavity 121 is also formed on the surface of the end cover 11. Optionally, the through hole 15 penetrates through the accommodation cavity 111, that is, through both side cover surfaces of the end cover 11. The human leg 42 extends into the physiotherapy cavity 121 through the through hole 15. The sealing structure 50 includes a sealing member made of a flexible and elastic material and filled in the accommodation cavity 111. Optionally, the sealing member has a sealing property and is arranged around the circumference of the human leg 42 to seal the human leg 42 and the cavity wall of the accommodation cavity 111 at the edge of the hole opening of the through hole 15, that is, the sealing member seals the human leg 42 around the circumference of the human leg 42, and at the same time seals the cavity bottom and the cavity top of the accommodation cavity 111 around the through hole 15, thereby preventing the gas in the physiotherapy cavity 121 from leaking. It can be understood that the aperture of the through hole 15 is larger than the diameter at any position of the human leg 42.

[0030] Please refer to Figures 1 to 3, by opening a through hole 15 in the end cap 11, the human leg 42 extends into the physiotherapy cavity 121 through the through hole 15. At the same time, the seal in the accommodation cavity is made of a flexible and elastic material with sealing properties. It adapts to human legs 42 of different diameters through elastic contraction and can well wrap and seal the human leg 42, which not only improves the application range of the sealing device but also improves the safety of the sealing device.

[0031] Please refer to Figures 1 to 3 , in one embodiment, the seal is an airbag ring 51 made of an elastic material. The airbag ring 51 is sleeved on the human leg 42, and the airbag ring 51 seals the human leg 42 in the inflated state. Optionally, the airbag ring 51 is made of a rubber material, and the volume of the airbag ring 51 increases with the increase of the internal air pressure until the two side ring surfaces of the airbag ring 51 respectively abut against the two side cavity walls of the accommodation cavity 111. It can be understood that, according to the predetermined pressure of ozone in the physiotherapy cavity 121, the internal pressure of the airbag ring 51 is set to balance the sealing performance of the airbag ring 51 and the comfort of wrapping the human leg 42. That is, when the ozone pressure and concentration in the physiotherapy cavity 121 are relatively high, the pressure of the airbag ring 51 can be appropriately increased, and vice versa. Thus, the sealing device 100 can not only adapt to human legs 42 of different diameters but also effectively seal the human leg 42 and the through hole 15, improving safety.

[0032] Optionally, the box body 12 is arranged in a sandwich structure with a vacuum area in the middle, which is beneficial to the heat preservation of the physiotherapy cavity 121.

The cover body 118 and the cover plate 119 jointly form the accommodation cavity 111, and the cover plate 119 presses the airbag ring 51 against the box body 12. Optionally, the cover body 118 has an inner cavity, and the cover plate 119 is detachably connected to the cover body 118 and presses the airbag ring 51, facilitating the installation and maintenance of the airbag.

[0035] Please refer to Figure 6, in one embodiment, the cover plate 119 is rotatably connected to the cover body 118, and a damping strip 191 is convexly provided on the plate surface of the cover plate 119 that abuts against the airbag ring 51. The cover plate 119 rotates relative to the cover body 118 by a predetermined angle to drive the airbag ring 51 to wind tightly around the human leg 42. Optionally, after the airbag ring 51 is inflated, the airbag ring 51 initially seals the human leg 42 and the through hole 15. Then, the cover plate 119 is rotated, and the damping strip 191 drives the airbag ring 51 to be twisted and deformed, so that the airbag ring 51 further winds tightly around the human leg 42, improving the sealing performance of the airbag ring 51. Optionally, a plurality of damping strips 191 are provided, and the extending paths of the damping strips 191 are arranged in an arc shape.

[0036] Please refer to Figures 4 to 6 , optionally, a positioning convex ring 153 is convexly provided on the plate edge of the cover plate 119, and a positioning ring groove 152 is opened on the cavity wall of the accommodating cavity 111 on the cover body 118. Through the cooperation of the positioning convex ring 153 and the positioning ring groove 152, the initial fixation of the cover plate 119 and the cover body 118 can be achieved, and the cooperation of the positioning ring groove 152 and the positioning convex ring 153 can guide the cover plate 119 to rotate smoothly.

[0037] Optionally, a positioning hole 117 is opened on the plate edge of the cover plate 119, and a threaded hole is opened on the cover body 118 corresponding to the position of the positioning hole 117. After the cover plate 119 rotates in place, the cover plate 119 and the cover body 118 can be further fixed by bolts.

[0038] Please refer to Figures 1 to 3 , in one embodiment, the sealing device 100 further includes a footrest provided in the physiotherapy cavity 121 and used for supporting the human leg 42. The footrest can place the human leg 42 in the physiotherapy cavity 121 for a long time, and a massage structure can also be provided on the footrest to activate the blood vessels in the sole of the foot and reduce the burden on the human body at the same time.

[0039] In one embodiment, fixing holes 116 are opened on the edge of the end cover 11, threaded holes are opened on the box body 12 corresponding to the positions of the fixing holes 116, and the housing structure 10 further includes positioning bolts. One end of the positioning bolt passes through the fixing hole 116 and is locked to the threaded hole.

[0042] Please refer to Figures 1 to 3 , optionally, an exhaust structure 20 is further provided on the box body 12. One end of the exhaust structure 20 is connected to the box body 12 and is used to discharge the gas in the physiotherapy cavity 121 out of the physiotherapy cavity 121. Before the human leg 42 enters the physiotherapy cavity 121, the exhaust structure 20 extracts the air in the physiotherapy cavity 121 out of the physiotherapy cavity 121, so that the ozone concentration in the physiotherapy cavity 121 is maintained at a predetermined value for effective physiotherapy of the human leg 42.

[0043] Please refer to Figures 1 to 3 , in one embodiment, both the exhaust structure 20 and the physiotherapy structure 30 are connected to the box body 12. Optionally, the box body 12 is in the shape of a cuboid or a cylinder, the cross-sectional shape of the physiotherapy cavity 121 is rectangular or circular, and both the exhaust structure 20 and the physiotherapy structure 30 are connected to the side surface of the box body 12.
