[0002] Fumigation therapy is a branch of external treatment for diseases. Fumigation therapy, also known as steaming therapy, is commonly used in Traditional Chinese Medicine (TCM) treatments and primarily includes steam bath therapy, drug penetration therapy, and hot mist therapy. Fumigation is a combination of chemical and physical therapies that uses hot drug vapor as a therapeutic agent. Fumigation includes both whole-body and local fumigation. This method of fumigation has been documented in clinical practice since ancient times. Since the founding of the People's Republic of China, with the rapid advancement of science and technology, fumigation has developed significantly in both theory and practice, gradually gaining widespread application in leisure and health care, rehabilitation, and clinical treatment of various diseases. Among the existing publicly available methods of fumigation therapy, the traditional method involves placing the drug in a container (made of stainless steel, porcelain, or porcelain sand), then adding water and boiling it. The boiling steam is then applied to the treatment area for approximately 20 to 30 minutes. Modern, optimized and improved fumigation methods utilize fumigation beds, fumigation chairs, and other fumigation devices of varying structures.

[0033] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0034] It should also be understood that, while the terms "first," "second," and the like are used herein to describe various types of information, such information should not be limited to these terms; these terms are merely used to distinguish information of the same type from one another. For example, "first" information could also be referred to as "second" information, and similarly, "second" information could also be referred to as "first" information without departing from the scope of this application.

[0035] like Figures 1 to 4As shown, the present invention provides a drug fumigation device for use in traditional Chinese medicine rehabilitation fumigation, which includes a heating cylinder 1, a conduit 2 and a fumigator 3; the fumigator 3 includes a fumigation base 31, a placement component 32, multiple spray heads 33 and multiple drive components 34. The top of the fumigation base 31 is formed with an arc-shaped working groove 311 to adapt to the shape of a human body part (such as an arm), and a flow channel with multiple liquid outlets is provided in the fumigation base 31. The heating cylinder 1 is used to heat the drug liquid to a suitable temperature so that it evaporates into steam. It is connected to the liquid inlet of the flow channel through the conduit 2 to guide the drug liquid steam into the flow channel. The spray head 33 is connected to the corresponding liquid outlet so that the heated drug liquid steam can be distributed to each spray head 33 through the liquid outlet; the placement component 32 is mounted on the working groove 311 for the patient to place his arm, and the spray head 33 is located in the working groove 311 to release the drug liquid steam directly to the patient's skin. The placement component 32 has a breathable structure so that the drug liquid steam sprayed by the spray head 33 can fumigate the arm to be fumigated.

[0036] Each driving assembly 34 includes a rotating seat 341 and a rotating structure 342. The rotating seat 341 is arranged in the working groove 311. The corresponding spray head 33 is installed on the rotating seat 341. One end of the rotating structure 342 passes through the fumigation base 31 and the rotating seat 341 and is connected to the spray head 33 to drive the spray head 33 to rotate horizontally, guide the direction and angle of the spraying of the liquid medicine vapor, and improve the treatment efficiency.

[0037] Based on the above structure, this embodiment drives the rotation of the spray head 33 by rotating the rotating structure 342, and then adjusts the tilt angle of the spray head 33 to achieve the effect of controlling the spray head 33 to spray in one direction, thereby ensuring that the spray head 33 can output in a directional manner, improving the targeted treatment and the utilization rate of the medicinal liquid vapor. At the same time, since the adjustment angle of the spray head 33 is controllable, it is easy to meet personalized treatment needs. For example, the patient's arm can be fumigated at multiple points, and the spray angle of the spray head 33 can be adjusted as needed so that the steam is sprayed in one direction to avoid directly fumigating the patient's arm vertically, and the overflowed medicinal liquid vapor is used for fumigation. In addition, the steam can also be sprayed in one direction as needed so that the medicinal liquid vapor is directly fumigated toward the position on the patient's arm that needs to be fumigated. The spray head 33 of this embodiment can be connected to the liquid outlet by a liquid guide hose.

[0038] See also Figure 5The drive assembly 34 also includes a rack 343, a gear portion 344, and a push plate 345. A first slide groove 312 is provided on one side wall of the fumigation base 31 along the length of the working groove 311. The push plate 345 is located outside the fumigation base 31, and one side of the push plate 345 is slidably mounted on the first slide groove 312. The rack 343 is mounted on the push plate 345. The movement of the push plate 345 can drive the rack 343 to move linearly. The gear portion 344 is mounted on the end of the rotating structure 342 located outside the working groove 311 and meshes with the rack 343, allowing the operator to indirectly control the direction and angle of the spray head 33 by controlling the position of the push plate 345. When the rack 343 moves, the rotation of the gear portion 344 drives the rotating base 341 (and the spray head 33 thereon) to rotate horizontally, which can achieve angle adjustment of the spray head 33 and ensure that the liquid vapor can be fumigated toward the area to be fumigated.

[0039] It should be noted that the drive assembly 34 of this embodiment also includes a drive member, which is mounted on the fumigation base 31 and connected to the push plate 345. The drive member can be manually controlled (such as a knob or handle) or electrically driven, and is used to push the push plate 345 to move along the first slide 312. In this embodiment, the position of the push plate 345 is adjusted manually or automatically, and the meshing relationship between the rack 343 and the gear portion 344 is utilized to enable the rotating structure 342 to drive the spray head 33 to rotate in the horizontal direction, thereby achieving control of the fumigation angle. This not only improves the treatment effect, but also adapts to the individual differences of different patients, increasing the applicability of the device.

[0040] Furthermore, the fumigator 3 also includes a limiting assembly 35, which includes a limiting plate 351, a first spring member 352, a first connecting rod 353, and a limiting block 354. The limiting plate 351 is mounted on one side of the fumigation base 31 and serves as a fixed support structure for the entire limiting assembly 35, providing a guide and limiting reference for the first connecting rod 353. One end of the first connecting rod 353 is connected to the push plate 345, and the other end of the first connecting rod 353 passes through the limiting plate 351 and is connected to the limiting block 354. The limiting block 354 acts as a physical limit. When the push plate 345 moves to a certain extreme position, the limiting block 354 will abut against the limiting plate 351, thereby preventing the push plate 345 from further movement and preventing the first connecting rod 353 from detaching from the limiting plate 351. The first spring member 352 is sleeved on both ends of the first connecting rod 353, and the two ends of the first spring member 352 are respectively in contact with the push plate 345 and the limit plate 351. When the external force (such as the push of the driving member) is removed, the first spring member 352 can restore the push plate 345 to its original position. In addition, when adjusting the angle of the spray head 33, the first spring member 352 can also absorb vibration or impact during the movement, thereby improving the operation stability.

[0041] Based on the above structure, the push plate 345 of this embodiment is pushed by the driving member, causing the spray head 33 to rotate. When the desired angle is reached, the push stops (if the limit position is reached, the limit block 354 hits the limit structure and stops moving forward). At this time, the first spring member 352 maintains a certain tension to prevent the spray head 33 from deviating from the target position due to vibration or external interference. If the original position needs to be restored, after releasing the push plate 345, the first spring member 352 automatically rebounds and pushes the push plate 345, thereby causing the spray head 33 to return to its original position.

[0042] It should be noted that in this embodiment, if the push plate 345 is pushed manually, it is necessary to limit the push plate 345 by manually and continuously resisting it or setting a resisting structure to prevent it from resetting during operation due to the elastic force of the first spring member 352.

[0043] like Figure 2 and Figure 6 As shown, the placement component 32 includes a curved placement plate 321, an adhesive layer 322 and a breathable towel 323. The curved placement plate 321 is mounted on the working groove 311. The curved placement plate 321 is curved in shape to better fit human body parts (such as arms) to improve comfort and fumigation effect. The curved placement plate 321 is provided with a breathable mesh 3211, so that the medicinal liquid vapor can rise from the working groove 311 below through the breathable mesh 3211 and contact the part to be fumigated. The adhesive layer 322 is disposed on the inner wall of the curved placement plate 321 and on both sides of the breathable mesh 3211. It is used to secure the subsequently installed breathable towel 323, firmly attaching the breathable towel 323 to the curved placement plate 321. That is, the breathable towel 323 is attached to the curved placement plate 321 via the adhesive layer 322 and covers the breathable mesh 3211, preventing the patient from directly contacting the hot curved placement plate 321 while increasing its softness against the skin and improving user comfort. It is understood that the breathable towel 323 of this embodiment is secured by the adhesive layer 322, making it easy to remove, clean, or replace.

[0044] In addition, the provision of the breathable towel 323 not only allows the medicinal liquid vapor to pass through the breathable mesh 3211 and the breathable towel 323 for cooling and then directly adhere to the patient's area to be fumigated, thereby increasing the residence time of the medicinal liquid vapor on the surface of the patient's area to be fumigated and improving the quality and effect of Chinese medicine fumigation, but also can absorb water droplets or excess moisture after the condensation of the medicinal liquid vapor to keep the arms dry.

[0045] It should be noted that the arc-shaped placement plate 321 of this embodiment is provided with an opening, and the air-permeable mesh 3211 is a 316L stainless steel air-permeable mesh, which is installed in the opening. In some embodiments, the air-permeable mesh 3211 can be a mesh opened on the arc-shaped placement plate 321.

[0046] Furthermore, the placement component 32 also includes an inflatable airbag 324 and an air pump 325. The two inflatable airbags 324 are relatively arranged on both sides of the inner wall surface of the arc-shaped placement plate 321. The air pump 325 is installed on the outer surface of the arc-shaped placement plate 321 and is connected to the inflatable airbag 324 to inflate the inflatable airbag 324 to fix the arm.

[0047] The air pump 325 of this embodiment can be controlled manually or electrically to provide gas to the inflatable airbag 324. When fumigating the hands or forearms, if the arms move at will, it will affect the effective coverage of the steam. When inflated, it will expand, and gentle pressure can be applied to the arm to fix it in an ideal position, thereby fixing the arm and preventing it from sliding or shaking, so that the steam can act more evenly on the target area, thereby improving the stability of the contact between the arm and the steam and enhancing the fumigation effect. It is understandable that because the airbag is soft and elastic after inflation, it will not cause discomfort due to excessive pressure like hard materials. The airbag pressure can also be adjusted according to the user's body shape to meet the needs of different groups of people and avoid burns or other accidents caused by arm slipping.

[0048] Furthermore, the fumigator 3 further includes a controller 39 , which is mounted on the rear end of the right upper surface of the fumigation base 31 and is electrically connected to the air pump 325 to achieve controllable inflation of the airbag 324 .

[0049] like Figure 3 、 Figure 7 and Figure 8 As shown, the fumigator 3 also includes a baffle assembly 36, and a second slide groove 313 is opened on the side wall of the working groove 311. The two second slide grooves 313 are relatively arranged on the two side walls of the working groove 311, providing a sliding installation path for the baffle assembly 36, so that the baffle assembly 36 can move along the second slide groove 313 to achieve flexible adjustment of its position.

[0050] The baffle assembly 36 includes an arc-shaped baffle 361 and a guide plate 362. The arc-shaped baffle 361 has an arc-shaped structure to adapt to the shape of the working groove 311. One side of the guide plate 362 passes through a second slide groove 313 to be connected to the arc-shaped baffle 361, and the guide plate 362 is slidably installed in the second slide groove 313 to drive the arc-shaped baffle 361 to slide along the length direction of the second slide groove 313. The arc-shaped baffle 361 is installed in the working groove 311, and the side of the arc-shaped baffle 361 away from the guide plate 362 is slidably connected to the other second slide groove 313 to form a structure of sliding supports at both ends, ensuring that the baffle is stably installed in the working groove 311. At the same time, the sliding of the guide plate 362 can drive the overall sliding adjustment position to avoid its displacement during the movement.

[0051] In this embodiment, the sliding of the guide plate 362 drives the arc-shaped baffle 361 to move, thereby adjusting the position of the baffle in the working groove 311. The baffle position can be flexibly adjusted according to different usage requirements (such as steam volume and fumigation area size) to block the steam nozzle in the designated area. The steam nozzle can be blocked at the patient's discomfort area to prevent the liquid medicine vapor from directly fumigating the patient's discomfort area and causing an impact.

[0052] The upper surface of the arc-shaped baffle 361 is provided with a push groove for allowing the liquid medicine vapor to overflow from the push groove to prevent the liquid medicine vapor from directly fumigating the patient's uncomfortable area. It is understandable that the arc-shaped baffle 361 of this embodiment may also be provided with a push groove, which is not particularly limited here.

[0053] Furthermore, the baffle assembly 36 also includes a placement rack 363, a pull ring 364, a second connecting rod 365, a second spring member 366 and a first magnetic member 367. The placement rack 363 of this embodiment is used to install a bracket for other parts. It is installed on the side of the guide plate 362 away from the arc-shaped baffle 361. One end of the second connecting rod 365 is connected to the first magnetic member 367, and the other end of the second connecting rod 365 passes through the placement rack 363 and is connected to the pull ring 364. The second connecting rod 365 is pulled by the pull ring 364, driving the first magnetic member 367 to move, thereby changing the magnetic state. The second spring member 366 is sleeved on the outer peripheral side of the second connecting rod 365, and the two ends of the second spring member 366 are respectively in contact with the first magnetic member 367 and the placement frame 363. When the pull ring 364 is pulled out and released, the second spring member 366 can automatically push the first magnetic member 367 back to its original position, so that the second magnetic member 373 automatically returns to the adsorption state after the pull ring 364 is released.

[0054] A through hole is provided on the guide plate 362 of this embodiment, and the first magnetic component 367 can be magnetically connected to the fumigation base 31 through the through hole to achieve fixation between the baffle assembly 36 and the fumigation base 31. The pull ring 364 can pull the first magnetic component 367 along the length direction of the second connecting rod 365 to release the magnetic connection with the fumigation base 31, thereby achieving rapid disassembly or position adjustment of the baffle assembly 36.

[0055] Based on the above structure, this embodiment uses the first magnetic component 367 to achieve rapid adsorption and fixation of the baffle assembly 36 and the fumigation base 31. The magnetic attraction can be released by pulling the pull ring 364, which facilitates the adjustment or removal of the arc baffle 361. The second spring component 366 ensures that the second magnetic component 373 automatically resets and re-adsorbs after the pull ring 364 is released. The first magnetic component 367 is adsorbed on the surface of the fumigation base 31 through magnetic attraction to prevent the arc baffle 361 from shaking during use.

[0056] like Figure 9As shown, the fumigator 3 also includes a water collection component 37 for collecting condensed water or residual liquid that has not evaporated after spraying to prevent dripping or polluting the environment. The fumigation base 31 has a water collection tank 314 and a receiving tank connected to the water collection tank 314. The water collection tank 314 is opened on the bottom wall of the working tank 311. The water collection tank 314 can guide and collect the water droplets condensed from the liquid vapor produced by the spray head 33. The spray head 33 is located above the water collection tank 314, so that the liquid after the sprayed liquid vapor is condensed will fall into the working tank 311 and be collected by the water collection tank 314. The receiving tank is formed from one side of the fumigation base 31 along the length direction of the fumigation base 31 and is located below the water collection tank 314 to serve as the installation space for the water collection component 37, so that the condensed liquid can accurately fall into the interior of the water collection component 37.

[0057] The water collection assembly 37 includes a water collection box 371, a pull plate 372, and a second magnetic component 373. The water collection box 371 is used to finally collect the liquid and prevent it from overflowing. The pull plate 372 is installed at one end of the water collection box 371, and the other end of the water collection box 371 is slidably installed in the receiving groove. The design of the pull ring 364 makes it easy for the user to pull out or push the water collection box 371. The second magnetic component 373 is installed on both sides of the water collection box 371 and can be magnetically connected to the fumigation base 31 to play a fixing role. One end of the water collection box 371 of this embodiment (not the pull plate 372 end) is slidably installed in the receiving groove, and the pull plate 372 end is fixed to the fumigation base 31 by adsorption through the second magnetic component 373, which not only ensures the stability of the water collection box 371 during use, avoids the water collection box 371 from shaking during use and causing leakage of fumigated sewage, but also makes it easy for the user to pull it out for cleaning.

[0058] Furthermore, the fumigator 3 includes a lifting assembly 38, which connects the fumigation base 31 to the placement assembly 32. This allows the height of the placement assembly 32 to be adjusted vertically to control the steam temperature and ensure comfortable use. Furthermore, the height of the placement assembly 32 can be adjusted to accommodate different heights or sitting heights of users, enhancing user comfort. The lifting assembly 38 can be an electric lift lever, driven by a motor to raise and lower the telescopic rod.

[0059] like Figure 1 As shown, a sealing cover 11 is installed on the upper surface of the heating cartridge 1, creating a closed structure within the cartridge 1 to prevent contamination of the medication and allow moisture from the heated medication to flow toward the conduit 2 mounted at the upper edge of the sealing cover 11. A control panel 12 is installed on the sealing cover 11 for setting heating parameters. Furthermore, an intelligent temperature control module is installed within the heating cartridge 1 for heating the medication solution within the cartridge 1. This intelligent temperature control module is electrically connected to the control panel 12.

[0060] The method of use is as follows: Before starting fumigation treatment, medical staff inject traditional Chinese medicine concentrate and purified water in proportion through the medicine inlet located above the sealing cover 11 on the top of the heating cylinder 1. After setting the initial heating parameters through the control panel 12, the system will activate the intelligent temperature control module to accurately control the temperature rise rate of the liquid medicine in the heating cylinder.

[0061] During the patient preparation phase, the nurse first smoothly adheres a breathable towel 323 (medical-grade) to the inner wall of the curved placement plate 321 via an adhesive layer 322 (medical-grade silicone adhesive). After the patient places the arm to be fumigated in the appropriate position, the controller 39 triggers the air pump 325 to inflate the airbag 324, achieving a stepped pressure adjustment. This ensures that the ergonomically fitting pressure of 2.5 kPa is reached within 30 seconds, ensuring stable exposure of the treatment area while avoiding any discomfort caused by compression.

[0062] When the medicinal liquid is heated to a set temperature, typically 85-95°C, the saturated medicinal liquid vapor is transported to the fumigation base 31 through the conduit 2. The array of spray nozzles 33 distributed within the fumigation base 31 sprays the medicinal liquid vapor. The medicinal liquid vapor penetrates the air-permeable mesh 3211 of the curved placement plate 321, then diffuses through the breathable towel 323, ultimately acting on the treatment area at an appropriate temperature.

[0063] During fumigation, if the angle of the spray head 33 needs to be adjusted for targeted spraying, the operator can push the push rod forward or backward to drive the rack 343 to slide along the first slot 312. This causes the rack 343 to rotate the gear portion 344 on the rotating structure 342, thereby rotating the spray head 33 along the rotating base 341. When the spray head 33 rotates to a certain angle, targeted fumigation is performed on the patient's affected area. After spraying is completed, the push rod can be released, and its first spring member 352 will reset the rack 343 through its reset property, returning the spray head 33 to its initial position. To address a restricted area, the operator first pulls the pull ring 364 to slide the first magnetic member 367 along the length of the second connecting rod 365, releasing the magnetic connection between the first magnetic member 367 and the fumigation base 31. The operator then slides the curved baffle 361 along the second slot 313 into the designated position, thereby precisely shielding the specific spray head 33 and ensuring precise control of the treatment area.

[0064] The condensed water generated during the treatment process is guided by gravity, guided by the water collection tank 314 and finally falls into the water collection box 371 for collection; after the water collection box 371 is full, the pull plate 372 can be pulled to release the adsorption of the second magnetic component 373 and the surface of the fumigation base 31, and then the water collection box 371 can be pulled out from the bottom of the fumigation base 31 to clear the accumulated water.

[0065] The drug fumigation device realizes the precision, intelligence and humanity of traditional Chinese medicine fumigation treatment through the collaborative work of multiple modules. While ensuring the treatment effect, it greatly improves the operation convenience of medical staff and the comfort of patients.

[0066] In summary, an embodiment of the present invention provides a drug fumigation device, which drives the rotation of the spray head 33 by rotating the rotating structure 342, and then adjusts the tilt angle of the spray head 33 to achieve the effect of controlling the spray head 33 to spray in one direction, thereby ensuring that the spray head 33 can output in a directional manner, improving the targeted treatment and the utilization rate of the medicinal liquid vapor. At the same time, since the adjustment angle of the spray head 33 is controllable, it is easy to meet personalized treatment needs. For example, the patient's arm can be fumigated at multiple points, and the spray angle of the spray head 33 can be adjusted as needed to make the steam spray in one direction, avoiding direct vertical fumigation of the patient's arm, and using the overflowed medicinal liquid vapor for fumigation. In addition, the steam can also be sprayed in one direction as needed, so that the medicinal liquid vapor is directly fumigated toward the position on the patient's arm that needs to be fumigated.

[0067] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
