Description

Technical Field

[0001] This invention relates to the field of physiotherapy and health care technology, and in particular to a fumigation structure and a health care knee brace. Background Technology

[0002] Fumigation therapy is one of the important methods of external treatment in traditional Chinese medicine. It uses heat to make the effective components of the medicine volatilize and act on the human body surface or affected area to achieve the effects of warming the meridians and promoting blood circulation, relieving pain, and dispelling wind and cold. It is widely used in the rehabilitation treatment of chronic diseases such as knee arthritis and sports injuries.

[0003] However, currently available fumigation therapy devices still have many limitations, restricting their full efficacy and ease of use. Firstly, existing devices are functionally limited, only capable of using a single form of medication: either solid fumigation (such as medicated cakes or ointments) or liquid fumigation (such as liquid vaporization). When patients require the combined or alternating use of different forms or formulations of medication depending on changes in their condition or complex symptoms, multiple devices must be replaced or equipped, leading to a cumbersome treatment process and hindering the implementation of personalized comprehensive treatment plans. Secondly, traditional heating methods often use solid heat sources such as heating wires or thermistors to directly heat the medication or carrier. These methods have large temperature gradients and limited control precision, easily causing skin burns or destruction of the active ingredients due to localized overheating, making it difficult to guarantee the safety and stability of the treatment. Summary of the Invention

[0004] One of the objectives of this invention is to provide a fumigation structure that enables the convenient and safe alternation of multiple drugs through the rotation of a rotating cylinder, and, in conjunction with a fumigation liquid supply module, solves the problems of existing devices having limited functionality, complex operation, and potential safety hazards.

[0005] The objective of this invention is achieved through the following technical solution: a fumigation structure, comprising a knee brace module, an integrated fumigation assembly, and a fumigation liquid supply module; the knee brace module comprises a solid cylinder and an annular airbag; the integrated fumigation assembly comprises a rotary cylinder, a rotary cylinder seat, a solid fumigation chamber, a liquid fumigation chamber, a water heating pipe, and a steam pipe; and the fumigation liquid supply module comprises a liquid supply module and a fastener.

[0006] The fixed cylinder is fixed to the outside of the knee pad module, the annular airbag is fixed to the inside of the knee pad module, the rotating cylinder is screwed to one end of the inner cavity of the fixed cylinder through the rotating cylinder seat, and the fastener is fixed to the outside of one end of the fixed cylinder. The inner cavity of the rotating cylinder is divided into a liquid fumigation chamber and multiple solid fumigation chambers. The water heating pipe is located in the inner cavity of the solid fumigation chamber, and the steam pipe is located in the inner cavity of the liquid fumigation chamber. The inlet and outlet ends of the water heating pipe and the steam pipe are both inserted into the main body of the rotating cylinder seat, and the outlet end of the steam pipe is sealed with a plug.

[0007] The rotary cylinder seat and the buckle seat are sealed and screwed together. The main body of the buckle seat is connected to the liquid outlet pipe and the liquid return pipe. Both the liquid outlet pipe and the liquid return pipe are connected to the liquid supply module.

[0008] The liquid supply module is an integrated liquid management and supply unit, including a liquid container, heater, pump body, and solenoid valve. The side wall of the liquid container is connected to a normally closed drain pipe, which can discharge clean wastewater.

[0009] The technical solution of this invention is used as follows:

[0010] The knee brace module can softly and snugly wrap around the knee using a ring-shaped airbag;

[0011] The liquid supply module can hold both the pure water used to heat the solid fumigation chamber and the medicinal liquid used for fumigation.

[0012] Both the solid fumigation chamber and the liquid fumigation chamber have through holes on their side walls;

[0013] That is, it can form the following two modes:

[0014] Mode 1: The fumigation agent is in the form of granules or paste. Different types of fumigation agents can be placed into different solid fumigation chambers and squeezed into contact with the water heating pipes. In this mode, it is possible to wear the product once and rotate it multiple times, allowing for the combined fumigation of the affected area with different types of solid agents.

[0015] At this time, enough pure water is added to the liquid supply module. By rotating the rotary drum, the inlet and outlet ends of the water heating pipes of different groups can be directly connected to the outlet pipe and return pipe respectively, and the solid fumigation chamber of the current group is directly opposite the annular airbag.

[0016] The pure water is heated to a set temperature by the liquid dispenser in the liquid supply module and pumped to the outlet pipe. The heated pure water then enters the water heating pipe and flows back to the liquid supply module through the return pipe for reheating and pumping. This cycle forms a water heating system for the water heating pipe. The heat generated can act on the solid agent, thereby achieving the fumigation effect of the solid agent.

[0017] In Mode 2, the fumigant is a liquid and needs to be added to the liquid supply module. In this mode, fumigation can only be achieved through the steam pipeline. At this time, a diffusion carrier formed by non-woven fabric filler needs to be placed in the inner cavity of the liquid fumigation chamber.

[0018] By rotating the cylinder, the inlet end of the steam pipe is connected to the outlet pipe, and at this time, the fumigation chamber of the medicine solution is directly opposite the annular airbag.

[0019] After the liquid medicine in the supply module is added to the set temperature, it is pumped into the steam pipeline through the liquid outlet pipe. The wall of the steam pipeline has capillary micropores, which allows the liquid medicine to act on the non-woven fabric filler in the form of steam atomization in the liquid medicine fumigation chamber. Through the transfer and buffering of the non-woven fabric filler, a liquid medicine steam fumigation operation can be formed.

[0020] Another object of the present invention is to provide a health care knee brace, which further includes a pre-strap assembly and an outer strap assembly. The pre-strap assembly is provided on both the upper and lower sides of the knee brace module. The pre-strap assembly includes a support part and an elastic strap. The outer strap assembly includes an outer fixing sleeve, an outer connecting strap and a zipper.

[0021] One end of the support is connected to an adjustment buckle, and the other end is connected to an elastic strap. The other end of the elastic strap is fastened to the adjustment buckle. By adjusting the fastening position of the elastic strap and the adjustment buckle, the tightness of the support and the elastic strap can be adjusted.

[0022] Connecting buckles are arranged and fixed on the end face of the support part, and fixed buckles are arranged and fixed on both ends of the main body of the knee pad module. An elastic Velcro strap connects the connecting buckle and the fixed buckle on the same side. By adjusting the sticking position of the elastic Velcro strap, the position of the pre-strap component relative to the knee pad module can be adjusted.

[0023] The outer retaining sleeve overlaps the main body of the knee brace module and does not interfere with the connection between the elastic Velcro strap and the retaining buckle. The two sides of the outer connecting strap are connected to the two sides of the outer retaining sleeve by zippers, which can strengthen the stable connection of the knee brace module to the knee area.

[0024] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0025] (1) This invention integrates multiple independent solid fumigation chambers with one liquid fumigation chamber into a rotatable cylinder, creating a highly modular treatment platform. Users can freely choose to fill in different formulas of solid drugs or use liquid drugs according to the specific recovery stage or symptom type. They can also complete the alternating application of multiple solid drugs through simple rotation operation within a treatment cycle. This design gives users unprecedented freedom in treatment combinations, enabling a single device to cover different treatment needs, achieving true multi-effect of one machine, and significantly improving the application value of the device and the convenience of users managing their condition independently.

[0026] (2) The core structure of the present invention adopts the design concept of rotational alignment and connection. Users only need to rotate the cylinder to switch the treatment mode and drug type. All complex fluid channel docking is completed automatically inside without any manual connection of pipelines, which greatly reduces the operation threshold and the risk of misoperation.

[0027] (3) By centralizing heat source management to an independently set liquid supply module, the present invention achieves precise control of fumigation energy source; the system can strictly set and maintain different working temperatures according to the form of the medicine, ensuring that the solid medicine can be heated evenly to volatilize active ingredients, while the liquid medicine can be converted into steam mist at a suitable temperature; the fumigation heating method formed by heating the liquid avoids the risk of direct contact burns between traditional high-temperature components and the skin, forming a controlled heat release mode, which not only ensures the stable output of treatment dosage and intensity, but also fundamentally builds a safety barrier, so that efficient fumigation and user safety can be taken into account.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] like Figures 1-12 As shown, a fumigation structure and health care knee brace are provided, with a fixed cylinder 102 fixed on the outside of the knee brace module 1, an annular airbag 105 fixed on the inside of the knee brace module 1, a rotating cylinder 301 screwed to one end of the inner cavity of the fixed cylinder 102 through a rotating cylinder seat 302, and a buckle 404 fixed to the outside of one end of the fixed cylinder 102.

[0046] The inner cavity of the rotary cylinder 301 is divided into a liquid fumigation chamber 307 and multiple solid fumigation chambers 306. The water heating pipe 309 is located in the inner cavity of the solid fumigation chamber 306, and the steam pipe 310 is located in the inner cavity of the liquid fumigation chamber 307.

[0047] The inlet and outlet ends of the water heating pipe 309 and the steam pipe 310 are both inserted into the main body of the swivel base 302 and are located on the same circular path coaxial with the center of the swivel 301; the outlet end of the steam pipe 310 is sealed with a plug 312.

[0048] The rotary cylinder seat 302 is sealed and screwed to the buckle seat 404. The buckle seat 404 has an outlet pipe 402 and a return pipe 403 connected in its main body. Any set of water heating pipes 309 can be rotated to the position where the inlet and outlet ends are directly connected to the outlet pipe 402 and the return pipe 403, respectively. The steam pipe 310 can be rotated to the position where the inlet end is connected to the outlet pipe 402.

[0049] Both the outlet pipe 402 and the return pipe 403 are connected to the liquid supply module 401; the liquid supply module 401 is an integrated liquid management and supply unit, including a liquid container, a heater, a pump body, and a solenoid valve. A certain amount of pure water or medicine can be poured into the liquid container, and the heater and the pump body can pump the heated liquid into the water heating pipe 309 or the steam pipe 310.

[0050] When the liquid container is filled with pure water, both the outlet pipe 402 and the return pipe 403 controlled by the solenoid valve are in the open state. When the liquid container is filled with medicine, the outlet pipe 402 controlled by the solenoid valve is in the open state, and the return pipe 403 is in the closed state.

[0051] When alternating liquids, heated pure water can be used to automatically flush the internal pipes to ensure cleanliness. The side wall of the liquid container is connected to a normally closed drain pipe to discharge cleaning wastewater.

[0052] Furthermore, both the outlet tube 402 and the return tube 403 are made of flexible food-grade silicone tubing, allowing the knee to move freely; the fumigation supply module 4 is an independent external unit, connected to the buckle 404 on the knee pad module 1 only through the outlet tube 402 and the return tube 403, and uses a quick-connect connector to ensure that it is burden-free when wearing and using it.

[0053] The working principle is as follows:

[0054] The knee brace module 1 can softly fit and wrap around the knee through the ring airbag 105;

[0055] The liquid supply module 401 can hold both pure water for heating the solid fumigation chamber 306 and medicinal liquid for fumigation.

[0056] The heating power of the heater in the liquid supply module 401 is 100-300W to ensure that the liquid can be heated quickly to a temperature range of 50-70℃, and can be adjusted within this range according to the characteristics of the agent and the user's tolerance.

[0057] Both the solid fumigation chamber 306 and the liquid fumigation chamber 307 have through holes on their side walls to allow the particles of the fumigation agent to pass through and act on the affected area.

[0058] That is, it can form the following two modes:

[0059] In Mode 1, the fumigation agent is a granular or paste-like solid (e.g., different formula granules or cakes made from traditional Chinese medicines such as Artemisia argyi, safflower, Lycopodium clavatum, and Clematis chinensis; for these herbs, the volatile oil is one of the key active ingredients, and these volatile oils will accelerate their escape from the solid herbs and transform into gaseous molecules after being heated (usually above 50℃)). Different types of fumigation agents can be placed into different solid fumigation chambers 306 and squeezed into contact with the water heating pipes 309. In this mode, a single wearing and multiple rotation operations can be achieved, allowing for combined fumigation of the affected area with different types of solid agents (such as warming the meridians, promoting blood circulation, and removing dampness). At this time, the liquid supply module 401 is filled with... Sufficient purified water, through rotating the rotary drum 301, allows the inlet and outlet ends of different groups of water heating pipes 309 to be directly connected to the outlet pipe 402 and the return pipe 403 respectively, and the solid fumigation chamber 306 of the current group is directly opposite the annular airbag 105; the purified water is heated to the set temperature by the liquid adder in the liquid supply module 401 and pumped to the outlet pipe 402, so that the heated purified water enters the water heating pipes 309 and flows back to the liquid supply module 401 through the return pipe 403, is heated and pumped again, and so on, thus forming a water heating system for the water heating pipes 309. The heat generated can act on the solid agent, thereby achieving the fumigation effect of the solid agent;

[0060] After the fumigation of the current type of solid agent is completed, the rotating cylinder 301 drives the inlet and outlet ends of the subsequent group of water heating pipes 309 to be directly connected to the outlet pipe 402 and the return pipe 403 respectively, forming the fumigation operation of the subsequent type of solid agent.

[0061] In Mode 2, the fumigation agent is a liquid medicine (such as a decoction of traditional Chinese medicine compound with the effect of promoting blood circulation and removing blood stasis), which needs to be added into the liquid supply module 401. At this time, fumigation can only be achieved through the steam pipe 310. At this time, a diffusion carrier formed by non-woven fabric filler needs to be placed in the inner cavity of the liquid fumigation chamber 307.

[0062] By rotating the rotary cylinder 301, the inlet end of the steam pipe 310 is connected to the outlet pipe 402, and at this time, the fumigation chamber 307 and the annular airbag 105 are directly opposite each other.

[0063] After the liquid medicine in the liquid supply module 401 is added to the set temperature, it is pumped to the steam pipeline 310 through the liquid outlet pipe 402. The wall of the steam pipeline 310 is provided with capillary micropores, which will cause the liquid medicine to act on the non-woven fabric filler in the form of steam atomization in the liquid medicine fumigation chamber 307. Through the transfer and buffering of the non-woven fabric filler, a liquid medicine steam fumigation operation can be formed.

[0064] Furthermore, after use, the inner cavities of the solid fumigation chamber 306 and the liquid fumigation chamber 307, the connecting pipes between the liquid supply module 401 and the water heating pipe 309 and the steam pipe 310, as well as the parts that come into contact with the skin, all need to be cleaned and disinfected.

[0065] The specific structures of the knee brace module 1, the pre-strap assembly 2, and the external strap assembly 6 are as follows: Figure 2 and Figure 3 As shown, the annular airbag 105 is fixed to the inner side of the fixed base 103, the fixed housing 101 is fixed to the outer side of the fixed base 103, and the fixed cylinder 102 is fixed to the outer side of the fixed housing 101.

[0066] The ring-shaped airbag 105 is made of medical-grade thermoplastic polyurethane film. Its side wall is equipped with an inflation nozzle and is pre-filled with a certain amount of gas. The gas volume is determined by the requirement that the ring-shaped airbag 105 expands to fit the knee comfortably.

[0067] The main body of the fixed base 103 is provided with a vent hole 108, and the vent hole 108 is located within the coverage area of ​​the annular airbag 105. The bottom end of the cavity wall of the fixed cylinder 102 is provided with an alignment hole 104.

[0068] The main rotating seat 107 is fixedly installed at one end of the cavity of the fixed cylinder 102, and the rotating cylinder seat 302 is sealed and screwed to the main rotating seat 107;

[0069] Both ends of the housing 101 are fixed with fasteners 106 arranged on the lower outer part;

[0070] The knee pad module 1 has pre-strap components 2 on both the upper and lower sides. The support part 201 is made of high-density, low-elasticity anti-slip material (such as thickened nylon or composite fiber). Its function is to conform to the contour of the leg and provide stable primary fixation and pressure distribution. One end of the support part 201 is connected to an adjustment buckle 202, and the other end is connected to a high-elasticity, breathable knitted elastic strap 203. The other end of the elastic strap 203 is fastened to the adjustment buckle 202. By adjusting the fastening position of the elastic strap 203 and the adjustment buckle 202, the tightness of the support part 201 and the elastic strap 203 can be adjusted to adapt to the leg circumference of different users and ensure the comfort and firmness of the initial fixation.

[0071] The end face of the support part 201 is fixed with connecting buckles 204. On the same side, the connecting buckles 204 and the fixed buckles 106 are connected by an elastic magic band 205. The elastic magic band 205 is usually made of hook and loop adhesive fabric with unidirectional stretching characteristics. By adjusting its pasting position, the up and down position of the pre-binding band component 2 relative to the knee brace module 1 can be finely adjusted, so that the fumigation part can be accurately aligned with the knee injury area.

[0072] The function of the outer strap assembly 6 is to provide secondary reinforcement to prevent the device from shifting due to body movement during treatment. The outer fixing sleeve 601 overlaps the outer side of the fixing base 103 and does not interfere with the connection between the elastic magic band 205 and the fixing buckle 106. The outer connecting strap 602 is a wide, low-elasticity strap, and its two sides are connected to the two sides of the outer fixing sleeve 601 by zippers 603 respectively. By pulling and closing the zippers to tighten the outer connecting strap 602, the knee brace module 1 can significantly strengthen the hug and stable connection of the knee area, and improve the overall stability during treatment.

[0073] The specific structure of the integrated fumigation component 3 is as follows: Figure 4 , Figure 5 and Figure 6 As shown, a cover 303 is detachably connected to the opening at the other end of the fixed cylinder 102. A sealing sleeve 304 is fixedly fitted on the inner side of the cover 303. The sealing sleeve 304 is pressed against the opening at the other end of the rotating cylinder 301 to seal and allow the rotating cylinder 301 to rotate.

[0074] The inner cavity of the rotary cylinder 301 is divided into a liquid fumigation chamber 307 and multiple solid fumigation chambers 306 by a partition 305. The outer walls of the liquid fumigation chamber 307 and the solid fumigation chamber 306 are provided with fumigation release holes 308, and the outline of the fumigation release holes 308 is consistent with the outline of the alignment hole 104.

[0075] The main bodies of the rotary cylinder seat 302 and the rotary cylinder 301 are uniformly provided with fixing holes 311. The inlet and outlet liquid ends of the water heating pipe 309 and the steam pipe 310 are respectively inserted into the fixing holes 311 on the same side.

[0076] The water heating pipe 309 and the steam pipe 310 have the same pipe type and structure, both being U-shaped.

[0077] The specific structure of the fumigation liquid supply module 4 is as follows: Figure 8 and Figure 9 As shown, the outer end face of the buckle 404 is connected to the inlet pipe seat 405 and the return pipe seat 406. The sealing groove 407 is opened on the inner end face of the buckle 404, and both the inlet pipe seat 405 and the return pipe seat 406 are connected to the sealing groove 407. The outlet end of the outlet pipe 402 is connected to the inlet pipe seat 405, and the inlet end of the return pipe 403 is connected to the return pipe seat 406.

[0078] The perforated sealing gasket 408 is fixed in the sealing groove 407. The outer end of the rotary cylinder seat 302 is screwed into the sealing groove 407, and the end face is sealed and fitted with the perforated sealing gasket 408. The main body of the perforated sealing gasket 408 has a through hole that is directly opposite to the liquid inlet pipe seat 405 and the liquid return pipe seat 406.

[0079] Furthermore, any set of water heating pipes 309 can be rotated to a position where the inlet and outlet liquid ends are directly connected to the inlet pipe seat 405 and the return pipe seat 406, respectively, and the steam pipe 310 can be rotated to a position where the inlet end is connected to the inlet pipe seat 405.

[0080] Rotary positioning assembly 5 for positioning and rotating the rotating cylinder 301, such as Figure 10 and Figure 11 As shown, a handle 501 is fixed to the outer side of one end of the rotary cylinder 301 coaxially with the rotary cylinder seat 302. The outer circular surface of the handle 501 is evenly provided with positioning slots 502.

[0081] The irregular shell 503 is fixed to the outer end face of the buckle 404, and the shell cover 504 covers the opening at the outer end of the irregular shell 503. A sliding cavity 505 is provided on one side of the main body of the irregular shell 503. The positioning pin 507 is placed in the sliding cavity 505. Side sliding grooves 506 are provided on both sides of the sliding cavity 505. Ear seats 508 are fixed on both sides of the positioning pin 507. The ear seats 508 on the same side are slidably connected in the side sliding grooves 506. A spring piece 509 is locked between the outer end of the positioning pin 507 and the inner bottom surface of the sliding cavity 505, which allows the positioning pin 507 to naturally spring towards the side of the handle 501.

[0082] The other end of the side wall of the irregular shell 503 is provided with a toggle relief groove 510. The outer circular surface of the handle 501 passes through the toggle relief groove 510 and extends into the outside of the irregular shell 503. By rotating the handle 501, the rotating cylinder 301 can be rotated. During the rotation of the handle 501, the positioning pin 507 and the positioning groove 502 form an elastic engagement to position the rotation angle of the rotating cylinder 301, so that both the solid fumigation chamber 306 and the liquid fumigation chamber 307 can be rotated to the position directly opposite the alignment hole 104.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
