Description

Technical Field

[0001] This invention relates to the field of sitz bath technology, specifically to a postoperative fumigation sitz bath device with a double-cavity separation structure for anorectal surgery. Background Technology

[0002] Postoperative recovery after surgery for anorectal diseases (such as hemorrhoids, fistulas, and anal fissures) is a crucial part of the treatment process. Traditional Chinese medicine fumigation and sitz baths are widely used and effective external treatment methods. Fumigation utilizes the heat and medicinal properties of the herbal steam to promote local blood circulation, relieve spasms, reduce swelling, and alleviate pain. Sitz baths involve directly immersing the affected area in the herbal solution, which cleanses the wound, has antibacterial and anti-inflammatory effects, and promotes healing. Currently, postoperative fumigation in clinical settings and at home mainly relies on the following two methods:

[0003] 1. Traditional Basin Method: Patients use ordinary plastic basins, sitz bath basins, or other containers to decoct or prepare traditional Chinese medicine solutions for fumigation or sitz baths. This method has significant drawbacks:

[0004] Separation of functions and cumbersome operation: Fumigation and sitz baths usually require the use of different tools or multiple adjustments, which interrupts the process and makes the experience inconsistent.

[0005] Temperature is difficult to control precisely: It mainly relies on manual sensing and adding hot water for adjustment, which can easily cause the water temperature to be too high, resulting in scalding, or too low, affecting the therapeutic effect, posing safety hazards and unstable results.

[0006] Inappropriate posture poses risks: basins of fixed height cannot accommodate patients of different heights and body types. Maintaining a squatting or sitting posture for a long time can easily lead to fatigue, which is especially difficult for patients who are weak, have difficulty moving, or are elderly after surgery. Furthermore, getting up can easily cause dizziness, falls, or other secondary injuries.

[0007] 2. Existing Electric Sitz Baths: Some electric sitz bath products have appeared on the market, typically featuring heating, temperature control, and showering functions, which to some extent improve upon the shortcomings of traditional bathtubs. However, these products still have the following limitations:

[0008] Limited functionality and fixed modes: Most products focus only on sitz baths or rinsing, failing to achieve a true "fumigation before bathing" or "fumigation and bathing in one" TCM treatment process. Steam generation functions are often rudimentary or absent, making it difficult to produce sufficient, continuous, and appropriately heated medicinal steam.

[0009] Low levels of automation and intelligence: Liquid level control and mode switching largely rely on manual operation, lacking integrated control. Height adjustment functions are rare, making it impossible to personalize the system for individual users.

[0010] Therefore, this invention proposes a postoperative fumigation and sitz bath device with a double-lumen separation structure for anorectal surgery to solve the above problems. Summary of the Invention

[0011] To overcome the shortcomings of the prior art, the purpose of this invention is to provide a postoperative fumigation and sitz bath device for anorectal surgery with a double-lumen separation structure.

[0012] To achieve the aforementioned objective, the technical solution of the present invention is implemented as follows: a postoperative fumigation and sitz bath device with a dual-cavity separation structure for anorectal surgery includes a sitz bath tub. A partition is fixedly installed inside the sitz bath tub, dividing the tub into a fumigation chamber and a collection chamber, which are arranged one above the other. A liquid-lifting plate is provided at the bottom of the tub, and a stud is provided at the center of the tub. The stud is threaded through the center of the liquid-lifting plate. A rotary drive is installed at the center of the bottom of the tub, and the stud is connected to the bottom end of the stud.

[0013] Preferably, the partition has a number of ventilation holes evenly distributed on it.

[0014] Preferably, an inlet valve pipe is installed at the top rear of the sitz bath tub, and a drain valve pipe is installed at the bottom rear of the sitz bath tub.

[0015] Preferably, a drain valve is installed on the liquid lifting plate, and the drain end of the drain valve is located below the liquid lifting plate.

[0016] Preferably, an electric heating tube is embedded inside the liquid lifting plate, a battery is installed at the rear end of the top of the liquid lifting plate, a charging base is installed at the bottom of the rear end of the partition, the electric heating tube is electrically connected to the battery, and a temperature sensor is also installed on the top of the liquid lifting plate.

[0017] Preferably, a controller is embedded inside the rear wall of the sitz bath tub.

[0018] Preferably, three electrically retractable columns are installed at the center of the front end and on both sides of the rear end of the sitz bath tub.

[0019] Preferably, a guide post is provided at both the front and rear ends of the sitz bath tub, and the front and rear guide posts are slidably connected to the front and rear ends of the liquid lifting plate.

[0020] Preferably, it further includes a control module, which is configured to:

[0021] Receive user instructions or preset programs to control the operation of the rotary drive component to drive the stud to rotate, thereby causing the liquid lifting plate to rise and fall along the guide column;

[0022] When fumigation is required in the fumigation chamber, control the liquid lifting plate to descend to the bottom or low position of the collection chamber so that the liquid level is lower than the partition. When sitz bath is required, control the liquid lifting plate to rise and push the liquid at the top upwards until the liquid level overflows the partition and reaches the preset sitz bath depth.

[0023] Preferably, the control module is further configured as an integrated control unit, which is electrically connected to the rotary drive, heating element, temperature sensor, valve of the inlet valve pipe, valve of the outlet valve pipe, and electric telescopic column; the control module coordinates and controls one or more of the following functions according to the operating mode:

[0024] The medicine is injected into the collection chamber through the inlet valve pipe;

[0025] The overall height of the sitz bath tub can be adjusted by controlling the extension and retraction of the electric telescopic column;

[0026] The medicine liquid is heated by an electric heating element, and the temperature of the medicine liquid is maintained in a first preset temperature range or a second preset temperature range based on the feedback from the temperature sensor. The first preset temperature range is suitable for fumigation mode, and the second preset temperature range is suitable for sitz bath mode.

[0027] After performing a sitz bath, the used medicine solution is discharged by controlling the descent of the liquid lifting plate and opening the valve of the drain valve pipe; or the drainage process is optimized by controlling the coordinated operation of the drain valve and the drain valve pipe.

[0028] The beneficial effects of this invention are reflected in:

[0029] Integrated Functions and Intelligent Mode Switching: Through an innovative dual-chamber design (fumigation chamber and liquid collection chamber) and a height-adjustable liquid lifting plate structure, this device perfectly integrates the traditionally separate fumigation and sitz bath functions into one unit. Under the coordination of the integrated control module, it can automatically and accurately switch between "fumigation mode" and "sitz bath mode." During fumigation, the liquid lifting plate descends, and the medicinal liquid is heated below to generate steam that rises; during sitz bath, the liquid lifting plate rises, pushing the medicinal liquid up to immerse the affected area. This eliminates the inconvenience of changing equipment or manual adjustment required in traditional methods, achieving "two uses in one device" and greatly improving the continuity and convenience of the treatment process.

[0030] Enhanced comfort and personalization of the treatment experience:

[0031] Height self-adaptive: Through the synchronous adjustment of three electric telescopic columns, the overall height of the sitz bath can be smoothly adjusted according to the user's height, body shape or usage habits to find the most comfortable sitting position. It is especially convenient for postoperative patients with limited mobility, reducing discomfort when bending over and getting up, as well as the risk of accidental falls and injuries.

[0032] Precise and intelligent temperature control: Integrating a temperature sensor and intelligent temperature control algorithm (such as PID control), it can automatically heat the medicinal solution and maintain it stably within the optimal temperature range according to the needs of different modes (higher steam generation temperature during fumigation, and a suitable therapeutic temperature for skin contact during sitz baths). This avoids the problems of difficult water temperature control, easy scalding, or poor effects in traditional methods, ensuring the safety and effectiveness of treatment.

[0033] Operational automation and process optimization:

[0034] Simplified operation steps: After the user selects the mode through a simple interface (buttons, touch screen, etc.), the device can automatically complete a series of actions such as injection, heating, lifting, heat preservation, and drainage, which greatly reduces the complexity of operation for the user and is especially suitable for patients whose self-care ability is temporarily limited after surgery.

[0035] Integrated cleaning function: The unique liquid-lifting plate and drain valve design, combined with the programmed control of the control module, enables an efficient internal cleaning process. The slight raising and lowering of the liquid-lifting plate agitates the water flow, and the coordinated operation of the two drain valves effectively removes residual medication, maintains the hygiene of the cavity, reduces the difficulty and workload of manual cleaning, and helps prevent cross-infection.

[0036] In summary, the postoperative fumigation and sitz bath device provided by this invention not only achieves the organic integration and one-button switching of fumigation and sitz bath functions through a clever mechanical structure and intelligent control system, but also makes significant progress in terms of treatment comfort, ease of operation, safety and hygiene, and ease of maintenance. It effectively solves the pain points of traditional postoperative fumigation and sitz baths, such as equipment separation, difficulty in water temperature control, cumbersome operation, and uncomfortable positioning, providing postoperative patients with an efficient, comfortable, intelligent, and humanized rehabilitation and physiotherapy tool, and has good clinical promotion value and application prospects.

[0054] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.

[0055] Implementation Method 1

[0056] like Figure 1-8 As shown, the present invention provides a postoperative fumigation and sitz bath device with a dual-cavity separation structure for anorectal surgery. Its core structure includes a sitz bath tub 1. A partition 2 is fixedly installed inside the sitz bath tub 1, which vertically divides the inner cavity of the tub 1 into two independent spaces: an upper fumigation chamber and a lower collection chamber. The partition 2 has several evenly spaced ventilation holes 21 to ensure that steam can smoothly rise from the lower collection chamber to the upper fumigation chamber.

[0057] A liftable liquid-lifting plate 3 is installed at the bottom inner side of the sitz bath tub 1. A stud 4 is vertically installed at the center of the interior of the sitz bath tub 1, with its bottom end extending to the outside of the tub bottom. A threaded hole is opened at the center of the liquid-lifting plate 3, and the stud 4 is threaded through this hole. A rotary drive 5 is installed at the center of the outer bottom of the sitz bath tub 1, and its output shaft is connected to the bottom end of the stud 4. When the rotary drive 5 is working, it drives the stud 4 to rotate. Since the liquid-lifting plate 3 is connected to the stud 4 by threads, it can achieve precise lifting and lowering movement of the liquid-lifting plate 3 within the liquid collection chamber. The bottom of the partition plate 2 is rotatably connected to the top of the stud 4 by a detachable bearing, and a sealing ring is provided at the connection between the partition plate 2 and the outer ring of the bearing. A nut with a sealing structure is detachably installed on the upper side of the liquid-lifting plate 3. The nut is threadedly connected to the stud 4, and the outer periphery of the nut is connected to the outer periphery of the bearing through a bellows to achieve a waterproof effect at the stud position. At the same time, a sealing ring is sandwiched between the liquid-lifting plate 3 and the nut to achieve a tight seal.

[0058] To facilitate the injection and discharge of the medicine solution, an inlet valve pipe 11 is installed at the top rear of the sitz bath tub 1, and a drain valve pipe 12 is installed at the bottom rear of the sitz bath tub 1. The inlet valve pipe 11 is usually connected to an external water source or medicine solution source and is used to inject liquid into the collection chamber; the drain valve pipe 12 is used to discharge the waste liquid after use.

[0059] A drain valve 31 is installed on the liquid lifting plate 3, with its drain end opening located below the liquid lifting plate 3. This design allows a small amount of liquid or cleaning fluid temporarily stored above the liquid lifting plate 3 to be directly drained into the bottom of the collection chamber below during specific operations (such as draining or cleaning), and then discharged uniformly through the drain valve tube 12, which helps to keep the instrument clean.

[0060] To achieve heating and temperature control of the medicinal liquid, an electric heating element 34 is embedded inside the lifting plate 3. A battery 32, which powers the electric heating element 34, is installed at the rear end of the top of the lifting plate 3. A charging base 9, connected to an external power source, is installed at the bottom of the rear end of the partition 2. When the sitz bath 1 is not in use or in standby mode, the battery 32 can be charged through the charging base 9. The electric heating element 34 is electrically connected to the battery 32. Additionally, a temperature sensor 33 is installed on the top of the lifting plate 3 to monitor the temperature of the medicinal liquid in real time.

[0061] To enhance the automation and intelligence of the equipment, a controller 7 is embedded inside the tub wall at the rear of the sitz bath tub 1. This controller 7 serves as the control center for the entire equipment.

[0062] To accommodate different user heights and improve comfort, three electrically operated telescopic columns 6 are installed on both the front and rear sides of the bottom of the sitz bath tub 1. These columns 6 are synchronously extended and retracted by a controller 7, allowing for smooth adjustment of the overall height of the sitz bath tub 1.

[0063] To ensure that the lifting plate 3 remains horizontal and stable during lifting and lowering without deflection, a guide post 8 is vertically installed at both the front and rear ends inside the sitz bath tub 1. Sliding sleeves or guide holes are provided at corresponding positions inside the front and rear ends of the lifting plate 3, allowing it to slide through these two guide posts 8.

[0064] Implementation Method 2

[0065] Based on Implementation Method 1, this implementation method focuses on describing the working logic of the control module and the collaborative control method.

[0066] The sitz bath also includes an integrated control module (which can be integrated into the aforementioned controller 7). The control module is configured to receive commands from the user through an external interface (such as buttons, a touch screen, or a remote control), or to execute internally preset automatic programs, and to coordinate and control the various actuators.

[0067] Basic Lifting Control: The control module controls the rotary drive 5 to operate according to the operation mode instructions. When fumigation is required, the control module drives the rotary drive 5 to lower the liquid-lifting plate 3 to the bottom of the collection chamber or a lower position. At this time, the liquid level of the medicine injected into the collection chamber is lower than that of the partition 2, and the steam generated by heating can rise through the vent holes 21 on the partition 2 to the fumigation chamber to fumigate the affected area. When switching to a sitz bath, the control module controls the rotary drive 5 to work in the opposite direction, driving the liquid-lifting plate 3 to rise. The liquid-lifting plate 3 pushes the liquid at its top upward, and the liquid level rises until it overflows the partition 2 and reaches the preset sitz bath depth (this depth can be preset by the program or set by the user), allowing the affected area to be immersed in the liquid for a sitz bath.

[0068] Integrated Coordination Control: The control module, as an integrated control unit, is electrically connected to the rotary drive component 5, the heating element 34, the temperature sensor 33, the valves of the inlet valve pipe 11 and the outlet valve pipe 12, as well as all the electric telescopic columns 6. It can coordinate and control one or more of the following functions according to the selected operating mode (such as "fumigation mode," "sitz bath mode," "cleaning mode," etc.):

[0069] Automatic liquid injection: When liquid medicine needs to be injected, the control module can control the valve of the liquid inlet valve pipe 11 to inject a certain amount of liquid medicine into the liquid collection chamber.

[0070] Height adjustment: Users can input their height or comfortable height parameters, and the control module will automatically adjust the sitz bath tub 1 to a suitable height by controlling the synchronous extension and retraction of the electric telescopic column 6.

[0071] Intelligent temperature control: The control module controls the operation of the heating element 34 according to the current mode. In fumigation mode, based on feedback from the temperature sensor 33, the medicinal liquid is heated and maintained within a first preset temperature range (e.g., a higher temperature range for generating suitable steam, such as 50-70°C). In sitz bath mode, the medicinal liquid is heated and maintained within a second preset temperature range (e.g., a sitz bath temperature range suitable for direct skin contact, such as 38-42°C). The control module achieves precise and stable temperature control through PID algorithms or other control strategies.

[0072] Automatic drainage and cleaning: After the sitz bath, the control module can execute a drainage procedure: first, control the lifting plate 3 to descend to its lowest position, then open the valve of the drain valve pipe 12 to drain the waste liquid in the collection chamber. When internal cleaning is required, the control module can coordinate the control of the drain valve 31 and the drain valve pipe 12. For example, first, inject clean water into the area above the lifting plate 3 through the inlet valve pipe 11, then control the lifting plate 3 to slightly raise and lower to agitate the water flow, then open the drain valve 31 to drain the wastewater to the bottom of the collection chamber, and finally discharge it through the drain valve pipe 12, thereby optimizing the cleaning process.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
