Description

A smart sitz bath device that automatically adapts to body shape Technical Field

[0001] This invention relates to the field of medical and health care equipment technology, specifically to an intelligent sitz bath device that automatically adapts to body posture. Background Technology

[0002] Sitz baths, generally basin-shaped, are currently used in homes and hospitals for cleaning, sterilizing, and hydrotherapy of the buttocks, anus, and genitals. For hemorrhoid treatment, smart toilets and simple medicated bath basins are the mainstream options; there are no products specifically designed for specialized hospital treatment and rehabilitation. Because the treatment process is very cumbersome and easily affected by temperature, it's difficult to achieve the full efficacy of the medication. This causes considerable inconvenience for patients before, after, and during the recovery process.

[0003] For example, the intelligent sitz bath device CN110037909A is an intelligent sitz bath basin that integrates fumigation, washing, soaking, physiotherapy, sterilization, and drying. It is characterized by its ease of use, intelligence, and hygiene, allowing the medicinal solution to exert its effects more fully and directly on the affected area. While it avoids cross-infection between patients, due to the limitations of the sitz bath basin itself, it is difficult to make local adjustments for different users. This means that for different users, the perineum and anus are not fully exposed due to structural limitations, affecting the flushing and sterilization effect on the perineum and anus, and thus impacting the treatment outcome.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the present invention provides an intelligent sitz bath device that automatically matches body posture, which has the following beneficial effects:

[0027] 1. This type of intelligent sitz bath device automatically matches body posture. The posture adjustment mechanism supports the patient's posture while seated on the sitz bath chair. Based on the pressure range exerted by the patient's weight on the posture adjustment mechanism, it detects and analyzes the patient's body shape and whether their posture is correct. This assists in adjusting the posture of patients with different body shapes, allowing the device to simultaneously meet the needs of different patients' body shapes and postures. Then, through the movement of the movable parts of the posture adjustment mechanism, it assists the patient in adjusting their posture to the correct position, exposing the affected area. The affected area can then be rinsed by the spray mechanism or fumigated with medication through the atomizing mechanism. By adjusting the posture, the affected area is fully exposed, allowing the spray mechanism to thoroughly rinse the area, and the atomizing mechanism to effectively deliver the medication to the affected area, ensuring the effectiveness of both rinsing and fumigation.

[0028] 2. This type of intelligent sitz bath device that automatically matches body posture uses a posture judgment processor to summarize and compare the pressure areas of two pressure detection plates at the same time, indirectly judging the pressure on the two cushions. First, the patient's body shape is judged based on the total size of the two pressure areas, and then the two pressure areas are compared. When the area and position of the two pressure areas are similar, the patient's sitting posture is judged to be correct. Otherwise, the patient's sitting posture is judged to be incorrect. The posture detection mechanism adjusts the height and angle of the cushion according to the position of the two pressure areas to help the patient adjust to the correct sitting posture, ensuring the effectiveness of the subsequent medicated bath treatment.

[0029] 3. This type of intelligent sitz bath device, which automatically matches body posture, controls the raising and lowering of the seat cushion connected to the larger pressure-bearing area. It tilts the cushion towards the axis of symmetry between the two cushions to assist the patient in initially adjusting their posture. This ensures that the patient's weight is evenly distributed across the two cushions, so that after the initial adjustment, the affected area is directly above the axis of symmetry between the two cushions. Then, based on the larger offset reference point, the cushion is tilted in the opposite direction to assist the patient in readjusting their posture. This ensures that after the initial adjustment, the affected area is directly above the reference point, completing the assisted posture adjustment. It also raises the patient's feet, assisting in moving the affected area into the sitz bath basin, fully exposing the affected area to the center of the spray and atomization mechanisms for rinsing or fumigation. Thus, this intelligent sitz bath device, which automatically matches body posture, accurately matches different body shapes and postures, ensuring effective subsequent medicated bath treatment.

Detailed Implementation

[0042] 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, and 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.

[0043] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an intelligent sitz bath device that automatically matches body posture.

[0044] Please refer to the figure. An intelligent sitz bath device that automatically matches body shape includes a sitz bath chair 1 and a water tank 2, as well as a posture adjustment mechanism 3, a spray mechanism 4, an atomizing mechanism 5, and a steam sterilization mechanism 6. Before use, the steam sterilization mechanism 6 sterilizes the areas the patient will come into contact with. After the patient sits on the sitz bath chair 1, the posture adjustment mechanism 3 detects the patient's body shape, determines the patient's posture based on the body shape, and assists the patient in adjusting their posture to the correct position. After the patient's posture is adjusted to the correct position, the spray mechanism 4 rinses the affected area, and the atomizing mechanism 5 atomizes the medicinal solution for fumigation and washing of the affected area.

[0045] This type of intelligent sitz bath device that automatically adapts to body posture is also equipped with a sitz bath basin that matches the sitz bath chair 1. The sitz bath chair 1 is also equipped with a cover that can cover the posture adjustment mechanism 3. Each patient uses an independent sitz bath basin to avoid cross-infection. Before use, the patient first places the sitz bath basin in the corresponding position on the sitz bath chair 1, then closes the cover of the sitz bath chair 1. Through the controller on one side of the sitz bath chair 1, the steam sterilization mechanism 6 is activated. The steam sterilization mechanism 6 generates steam to sterilize the sitz bath basin and the posture adjustment mechanism 3. After sterilization, the patient sits on the sitz bath chair 1 at the support position of the posture adjustment mechanism 3. Based on the pressure range of the patient's weight on the posture adjustment mechanism 3, the patient's body shape and whether the patient's sitting posture is correct are detected. Then, through the movement of the movable parts of the posture adjustment mechanism 3, the patient is assisted in adjusting their sitting posture to the correct position, exposing the patient's affected area (perineum and anus) so that the affected area can be rinsed by the spray mechanism 4, or the affected area can be fumigated by the atomizing mechanism 5. By adjusting the sitting posture, the patient's affected area is fully exposed, so that the spray mechanism 4 can thoroughly rinse the affected area, and the atomizing mechanism 5 can fully act on the affected area after atomizing the medicine, ensuring the rinsing and fumigation effect on the patient.

[0046] The posture adjustment mechanism 3 can detect and analyze the patient's body shape according to the pressure range of the posture adjustment mechanism 3, and detect the patient's sitting posture according to the patient's body shape, so as to assist the patient's sitting posture adjustment for different body shapes. This makes the intelligent sitz bath device that automatically matches body shape can simultaneously meet the matching of different patient body shapes and sitting postures (postures), so that it can be widely used for medicated bath treatment for patients of different body shapes.

[0047] Furthermore, the posture adjustment mechanism 3 includes two seat cushions 31, a posture detection mechanism 32, and a posture correction mechanism 33; the posture detection mechanism 32 includes a pressure detection plate 321 and a posture judgment processor, with the pressure detection plate 321 embedded inside the two seat cushions 31 respectively; the pressure detection plate 321 is used to detect the pressure area transmitted from the patient's body weight through the seat cushion 31 to the pressure detection plate 321 when the patient sits on the seat cushion 311; the posture judgment processor is used to compare the pressure areas detected by the two pressure detection plates 321 to determine whether the patient's posture is correct.

[0048] When the patient sits on the cushion 31, the pressure generated by the patient's weight on the cushion 31 is transmitted to the pressure detection plate 321 of the posture detection mechanism 32. The pressure detection plate 321 can detect the pressure area of ​​the patient. After the posture judgment processor summarizes the pressure areas of the two pressure detection plates 321 at the same time, it compares them to indirectly judge the pressure situation of the two cushions 31. First, the patient's body shape is judged based on the total size of the two pressure areas. Then, the two pressure areas are compared. When the area and position of the two pressure areas are similar (similar means the difference is within 2% of the maximum value), the patient's sitting posture is judged to be correct. Otherwise, the patient's sitting posture is judged to be incorrect. The posture detection mechanism 33 adjusts the height and angle of the cushion 31 according to the position of the two pressure areas to help the patient adjust to the correct sitting posture and ensure the effectiveness of the subsequent medicated bath treatment for the patient.

[0049] Furthermore, the pressure detection plate 321 includes a mounting plate 3211, a plurality of pressure sensors 3212, and a pressure data processor; the plurality of pressure sensors 3212 are evenly distributed on the surface of the mounting plate 3211, and the detection data of each pressure sensor 3212 is transmitted to the pressure data processor for processing. The pressure data processor analyzes and processes the detection data to obtain the stress area of ​​the mounting plate 3211.

[0050] Among them, by detecting multiple pressure sensors 3212, when the pressure detection plate 321 is locally compressed, the pressure sensor 3212 at the local compression location can detect the force. By the number and location of these pressure sensors 3212, the force-bearing area of ​​the mounting plate 3211 can be obtained.

[0051] The posture determination processor records the force-bearing areas detected by the two pressure detection plates 321 as M and N, respectively; the posture determination processor calculates the total area S of the force-bearing areas M and N. m and S n And obtain the coordinates x of the centroids of the force-bearing regions M and N about the reference point o. m y m and x n yn The reference point o is any point on the axis of symmetry between the two seat cushions 31; the posture judgment processor's S m and S n The numerical relationship, and x m y m and x n y n The relationship between the patient's current sitting posture and the position can be used to determine whether the patient's current sitting posture is correct.

[0052] The posture determination processor performs the following steps to determine whether the patient's current sitting posture is correct:

[0053] S1, First compare S m and S n The size, take S m and S n The larger one is S 大 The smaller one is S 小 Calculate S 大 -S 小 / S 大 The value;

[0054] When S 大 -S 小 / S 大 When the value is ≥0.02, the patient's current sitting posture is considered incorrect.

[0055] S2, when S 大 -S 小 / S 大 When <0.02, compare y m and y n The size, take y m and y n The larger one is y 大 The smaller one is y 小 Calculate y 大 -y 小 / y 大 The value;

[0056] When y 大 -y 小 / y 大 When the value is ≥0.02, the patient's current sitting posture is considered incorrect.

[0057] S3, when S 大 -S 小 / S 大 When <0.02, and when y 大 -y 小 / y 大 When < 0.02, compare |x m | and |x nThe size of | is taken as |x m | and |x n The larger one is x. 大 The smaller one is x, calculate x. 大 -x 小 / x 大 The value;

[0058] When x 大 -x 小 / x 大 When the value is ≥0.02, the patient's current sitting posture is considered incorrect.

[0059] S4, when S 大 -S 小 / S 大 When <0.02, and when y 大 -y 小 / y 大 When < 0.02, and when x 大 -x 小 / x 大 When the value is <0.02, the patient's current sitting posture is considered to be correct.

[0060] Furthermore, the posture correction mechanism 33 includes two angle adjustment components 331. Each angle adjustment component 331 includes several electric telescopic rods 3311. The fixed end of the electric telescopic rod 3311 is fixed to the sitz bath chair 1, and the movable end of the electric telescopic rod 3311 is rotatably connected to the seat cushion 31. The multiple electric telescopic rods 3311 of each angle adjustment component 331 cooperate to drive the seat cushion 31 to move, adjust the angle of the plane on which the seat cushion 31 is located, and thus assist the patient in adjusting their sitting posture.

[0061] The posture correction mechanism 33 also includes a support foot pad 332, which is fixed to the movable part of the electric slide rail 333. The electric slide rail 333 can drive the support foot pad 332 to move. The support foot pad 332 rises from the lowest point, which can raise the patient's foot position and help the patient move the affected area into the sitz bath.

[0062] When a patient's sitting posture is determined to be incorrect, by comparing S... m and S n The size of the force, for the S with the larger force-bearing area 大 The angle adjustment components 331 connected to the corresponding seat cushion 31 are adjusted, and the reference point o is preferably the projection point of the center position of the rinsing or fumigation of the spray mechanism 4 and the atomizing mechanism 5 on the axis of symmetry between the two seat cushions 31. The cooperation between the multiple electric telescopic rods 3311 of the angle adjustment component 331 to drive the seat cushion 31 to move is a conventional means of adjusting the angle of the plane in the prior art, which will not be described in detail here.

[0063] Firstly, by analyzing S大 The angle adjustment component 331 connected to the corresponding seat cushion 31 controls the height adjustment, tilting the seat cushion 31 towards the axis of symmetry between the two seat cushions 31 to assist the patient in adjusting their sitting posture for the first time. This allows the patient's sitting posture to evenly distribute their weight on the two seat cushions 31, ensuring that after the initial posture adjustment, the patient's affected area is exactly above the axis of symmetry between the two seat cushions 31. Furthermore, after the initial posture adjustment, S... 大 -S 小 / S 大 <0.02, and x 大 -x 小 / x 大 <0.02;

[0064] Then according to y m and y n y in 大 Direction, position cushion 31 towards y 大 The device tilts in the opposite direction to assist the patient in readjusting their sitting posture, ensuring that the affected area is directly above the reference point o after the initial adjustment. This assists in adjusting the patient's posture. Then, the support foot pad 332 rises from its lowest point, raising the patient's feet and helping them move the affected area into the sitz bath. This allows the affected area to be fully exposed in the center of the spray mechanism 4 and the atomizing mechanism 5 for rinsing or fumigation. This intelligent sitz bath device, which automatically matches body shape, accurately matches different body shapes and postures, ensuring the effectiveness of subsequent medicated bath treatment.

[0065] Furthermore, the water storage tank 2 includes a pure water tank 21 and a medicine tank 22; the pure water tank 21 is connected to the spray mechanism 4, the atomizing mechanism 5 and the steam sterilization mechanism 6 respectively to supply pure water; the medicine tank 22 is connected to the spray mechanism 4 and the atomizing mechanism 5 to supply medicine; both the pure water tank 21 and the medicine tank 22 are equipped with a low-temperature heating mechanism, which is used to preheat the water in the pure water tank 21 and the medicine tank 22, thereby heating the water in the pure water tank 21 and the medicine tank 22 to a temperature suitable for medicinal bath through the heating of the low-temperature heating mechanism.

[0066] Among them, the pure water tank 21 is connected to the spray mechanism 4, the atomizing mechanism 5 and the steam sterilization mechanism 6 respectively to supply pure water for cleaning the patient's affected area and disinfecting the sitz bath when not taking a medicated bath; the medicine tank 22 is connected to the spray mechanism 4 and the atomizing mechanism 5 to supply medicine for the patient's needs for rinsing and fumigation.

[0067] The medicine tank 22 is also connected to a dosing tank 23, and the medicine tank 22 and the dosing tank 23 are connected. The dosing tank 23 is equipped with a hook 231, which can hang a medicated bath bag. The ingredients in the medicated bath bag first dissolve in the water in the dosing tank 23, and then disperse in the medicine tank 22 and the dosing tank 23 through the water connection between the medicine tank 22 and the dosing tank 23.

[0068] In this embodiment, a water circulation structure is provided between the medicine tank 22 and the dosing tank 23. Preferably, the water circulation structure consists of two stirring fans with opposite rotation directions. The stirring fans are located at the connection between the medicine tank 22 and the dosing tank 23 to form two water flow directions at the connection, so as to fully mix the medicine solution in the medicine tank 22 and the dosing tank 23. In this embodiment, the dosing tank 23 is provided with a cover to prevent bacteria and other pathogens from entering the medicine tank 22 through the dosing tank 23.

[0069] Before the medicated bath, the medicated bath bag is hung on the hook 231 set in the medicine box 23. Through the water circulation between the medicine tank 22 and the medicine box 23, the medicinal components in the medicated bath bag are fully dispersed in the medicine tank 22 and the medicine box 23.

[0070] Furthermore, the outlets of the spray mechanism 4, the atomizing mechanism 5, and the steam sterilization mechanism 6 are all located on the integrated nozzle 7, which can be moved from the sitz bath chair 1 into the sitz bath basin. The spray mechanism 4 provides water flow to the integrated nozzle 7 to rinse the patient's affected area. The atomizing mechanism 5 provides and atomizes the medicinal solution to the integrated nozzle 7 to fumigate the affected area. The steam sterilization mechanism 6 is also equipped with a high-temperature steam generator, which reheats the water heated by the low-temperature heating mechanism to generate high-temperature steam. The steam sterilization mechanism 6 provides high-temperature steam to the integrated nozzle 7 to sterilize the sitz bath chair 1, the sitz bath basin, and the integrated nozzle 7.

[0071] In this embodiment, the integrated nozzle 7 is preferably a retractable structure. When in use, the integrated nozzle 7 extends into the sitz bath basin and retracts into the sitz bath chair 1 when not in use, so as to reduce the entry of germs due to exposure and ensure the therapeutic effect of the medicated bath.

[0072] Working principle:

[0073] This type of intelligent sitz bath device that automatically matches body posture is also equipped with a sitz bath basin that matches the sitz bath chair 1. The sitz bath chair 1 is also equipped with a cover that can cover the posture adjustment mechanism 3. Each patient uses an independent sitz bath basin to avoid cross-infection. Before use, the patient first places the sitz bath basin in the corresponding position of the sitz bath chair 1, then closes the cover of the sitz bath chair 1, and starts the steam sterilization mechanism 6 through the controller on one side of the sitz bath chair 1. The steam sterilization mechanism 6 generates steam to sterilize the sitz bath basin and the posture adjustment mechanism 3.

[0074] After disinfection, the patient sits on the sitz bath chair 1 in the support position of the posture adjustment mechanism 3. The posture adjustment mechanism 3 detects the patient's body shape and whether the patient's sitting posture is correct based on the pressure range of the patient's weight on the posture adjustment mechanism 3. Then, through the movement of the movable parts of the posture adjustment mechanism 3, it assists the patient to adjust the sitting posture to the correct posture, thus exposing the patient's affected area (perineum and anus).

[0075] The posture adjustment mechanism 3 can detect and analyze the patient's body shape according to the pressure range of the posture adjustment mechanism 3, and detect the patient's sitting posture according to the patient's body shape, so as to assist the patient's sitting posture adjustment for different body shapes. This makes the intelligent sitz bath device that automatically matches body shape can simultaneously meet the matching of different patient body shapes and sitting postures (postures), so that it can be widely used for medicated bath treatment for patients of different body shapes.

[0076] When the patient sits on the cushion 31, the pressure generated by the patient's weight on the cushion 31 is transmitted to the pressure detection plate 321 of the posture detection mechanism 32. The pressure detection plate 321 can detect the pressure area of ​​the patient. After the posture judgment processor summarizes the pressure areas of the two pressure detection plates 321 at the same time, it compares them to indirectly judge the pressure situation of the two cushions 31. First, the patient's body shape is judged based on the total size of the two pressure areas. Then, the two pressure areas are compared. When the area and position of the two pressure areas are similar (similar means the difference is within 2% of the maximum value), the patient's sitting posture is judged to be correct. Otherwise, the patient's sitting posture is judged to be incorrect. The posture detection mechanism 33 adjusts the height and angle of the cushion 31 according to the position of the two pressure areas to help the patient adjust to the correct sitting posture and ensure the effectiveness of the subsequent medicated bath treatment for the patient.

[0077] The posture correction mechanism 33 also includes a support foot pad 332, which is fixed to the movable part of the electric slide rail 333. The electric slide rail 333 can drive the support foot pad 332 to move. The support foot pad 332 rises from the lowest point, which can raise the patient's foot position and help the patient move the affected area into the sitz bath.

[0078] When it is determined that the patient's sitting posture is incorrect, by comparing the sizes of Sm and Sn, the angle adjustment components 331 connected to the seat cushion 31 corresponding to the larger force-bearing area S are adjusted. The reference point o is preferably the projection point of the center position of the rinsing or fumigation of the spray mechanism 4 and the atomizing mechanism 5 on the axis of symmetry between the two seat cushions 31. The cooperation between the multiple electric telescopic rods 3311 of the angle adjustment component 331 to drive the seat cushion 31 to move is a conventional means of adjusting the angle of the plane in the prior art, which will not be described in detail here.

[0079] First, by controlling the height adjustment of the angle adjustment component 331 connected to the seat cushion 31 corresponding to S, the seat cushion 31 is tilted towards the axis of symmetry between the two seat cushions 31 to assist the patient in adjusting their sitting posture for the first time. This allows the patient's sitting posture to evenly distribute their weight on the two seat cushions 31, ensuring that after the initial posture adjustment, the patient's affected area is exactly above the axis of symmetry between the two seat cushions 31. Furthermore, after the initial posture adjustment, S... 大 -S 小 / S 大 <0.02, and x 大 -x 小 / x 大 <0.02;

[0080] Then according to y m and y n y in 大 Direction, position cushion 31 towards y 大 The device tilts in the opposite direction to assist the patient in readjusting their sitting posture, ensuring that the affected area is directly above the reference point o after the initial adjustment. This assists in adjusting the patient's posture. Then, the support foot pad 332 rises from its lowest point, raising the patient's feet and helping them move the affected area into the sitz bath. This allows the affected area to be fully exposed in the center of the spray mechanism 4 and the atomizing mechanism 5 for rinsing or fumigation. This intelligent sitz bath device, which automatically matches body shape, accurately matches different body shapes and postures, ensuring the effectiveness of subsequent medicated bath treatment.

[0081] Before the medicated bath, the medicated bath bag is hung on the hook 231 inside the medicine dispensing box 23. Through the water circulation between the medicine tank 22 and the medicine dispensing box 23, the medicinal components in the medicated bath bag are fully dispersed in the medicine tank 22 and the medicine dispensing box 23. After the patient adjusts his sitting position, the patient's affected area is rinsed by the spray mechanism 4, or the affected area is fumigated by the atomizing mechanism 5. By adjusting the sitting position, the patient's affected area is fully exposed, so that the spray mechanism 4 can fully rinse the affected area, and the atomizing mechanism 5 can fully act on the affected area after atomizing the medicinal solution, ensuring the rinsing and fumigation effect on the patient.

[0082] Example 2:

[0083] Unlike Embodiment 1, in this embodiment, the opening and closing time between the cover and the sitz bath chair 1 can be counted in the control device, and the cover can be closed under the control of the control device, and the cover and the sitz bath chair 1 can be locked in place under the action of the control device.

[0084] Furthermore, a mechanism is installed below the sitz bath to detect its removal. This mechanism detects whether the sitz bath is installed. If the sitz bath is not detected for 1 minute, the cover is lowered under the action of the control device, closing and locking the opening of the sitz bath chair 1. The steam sterilization mechanism 6 then disinfects the structure of the sitz bath chair 1, ensuring a sterile internal environment for each use of the smart sitz bath and preventing infection.

[0085] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
