Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of radiotherapy beds, in particular to a radiotherapy bed. BACKGROUND

[0002] Cancer patients often need to undergo radiotherapy, and during radiotherapy, the accurate positioning of patients is the key to ensuring treatment effectiveness and reducing side effects. Patients need to lie on a radiotherapy bed and move into a radiotherapy room. In the process of patient positioning, the traditional radiotherapy bed usually relies on manual operation or a complex sensor system, which not only increases the complexity and time-consuming nature of the operation, but also may affect the positioning accuracy due to sensor failure or calibration problems. In addition, patients stay on the treatment bed for a long time, and the hygiene of the pillow pad in direct contact with the skin is increasingly prominent, especially in the context of the normalization of influenza. How to achieve rapid, efficient and automated cleaning and disinfection to prevent cross-infection is a problem that needs to be solved in the current field of radiotherapy.

[0003] The existing radiotherapy bed often uses complex mechanical structures and a large number of sensors for position feedback and control when achieving multi-dimensional accurate positioning. Although this design meets the accuracy requirements to some extent, it also brings problems such as high cost, high failure rate and maintenance difficulty. For example, when fine adjustments of the X, Y, Z axes and the rotation angle of the patient are needed, multiple independent transmission mechanisms and sensor systems make the entire device large and complex, increasing the difficulty of manufacturing and maintenance. At the same time, the current cleaning of the pillow pad is mostly done by manual wiping or replacing disposable consumables, which is inefficient and cannot guarantee disinfection, posing a risk of cross-infection. Especially in a high-frequency medical environment, this cleaning method cannot meet the requirements of rapid turnover and high hygiene standards.

[0004] Therefore, it is of great significance to develop a radiotherapy bed that can simplify the mechanical structure, improve the load capacity, reduce the dependence on sensors, and at the same time have an automated cleaning and disinfection function, in order to improve the efficiency of radiotherapy, reduce operating costs, and ensure patient safety. SUMMARY

[0020] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0021] like Figures 1 to 13 As shown, an embodiment of the present invention provides a radiotherapy bed, including a ground rail 1 and a support frame 3 slidably mounted on the ground rail 1. A bracket 7 is symmetrically fixed on the support frame 3, and a second rack 9 is fixed on the support frame 3. A sliding plate 10 is slidably mounted on the support frame 7 along the Y-axis. A second motor 11 is disposed through the sliding plate 10, and the drive end of the second motor 11 is meshed with the second rack 9. A cross-arm lifter 14 is disposed on the sliding plate 10, a rotating platform 13 is connected to the cross-arm lifter 14, a tray 15 is connected to the rotating platform 13, and a bed board 21 is slidably mounted on the tray 15 along the X and Y axes. The invention also includes: Pillow support 24 is fixed to bed board 21; Pillow cushion 38 is positioned above pillow support 24; The wiping part is disposed inside the pillow support 24 and extends through the pillow support 24 and is connected to the pillow pad 38, so that the pillow pad 38 can be triggered by the pillow pad 38 to wipe and clean the pillow pad 38; the wiping part includes a trigger member disposed on the bottom wall inside the pillow support 24 and a pushing and wiping member disposed inside the pillow support 24, and the pushing and wiping member extends through the pillow pad 38, and the trigger member and the pushing and wiping member are electrically connected. The disinfection spray unit is located inside the pillow support 24 and is connected to the rubbing part and the pillow pad 38 to assist in cleaning the pillow pad 38 by spraying alcohol in conjunction with the rubbing part. The disinfection spray unit includes a storage component located on the top wall inside the pillow support 24 and a spray guide component that penetrates the pillow pad 38, and the spray guide component is connected to the storage component. The cleaning unit is disposed inside the pillow support 24 and extends through one end of the pillow support 24, and contacts the wiping surface of the wiping unit to cooperate with the spraying unit to clean the wiping surface of the wiping unit; the cleaning unit includes a receiving component fixed to the inner wall of the pillow support 24 and extending through one end of the pillow support 24, and a wiping component disposed inside the receiving component, and the wiping component contacts the wiping surface of the wiping component.

[0022] Specifically, a first rack 2 is fixed to the inner wall of the ground rail 1, a first motor 4 is fixed to the inner side of the support frame 3, a first gear 5 is connected to the drive end of the first motor 4, and the first gear 5 meshes with the first rack 2, a guard frame 6 is fixed on the ground rail 1, and the guard frame 6 is located between the first motor 4 and the support frame 3, a support seat 8 is fixed on the support frame 3, and the support seat 8 is located below the second rack 9 to support the second rack 9, the drive end of the second motor 11 is connected to the second rack 9, and the second gear 12 meshes with the second rack 9.

[0023] The ground rail 1 provides stable support for its top components and guides the support frame 3 to slide along the X-axis. The support frame 3 can move all the components above it together, and it also provides stable support for the first motor 4. The first motor 4 drives the first gear 5 to rotate, causing the first gear 5 to push the support frame 3 to slide along the X-axis of the first rack 2 and the ground rail 1 using its meshing with the first rack 2 and rotational power. The guard frame 6 provides protection for the first rack 2, the first motor 4, and the first gear 5. The support frame 3 also provides stable support for the bracket 7 and the support base 8. The support base 8 provides stable support for the second rack 9. The support bracket 7 provides a guiding support for the slide plate 10 to slide along the Y-axis, and the slide plate 10 provides support for the second motor 11. The second motor 11 can drive the second gear 12 to rotate, and use the rotational power of the second gear 12 and its meshing with the second rack 9 to push the slide plate 10 to slide along the Y-axis of the second rack 9. The slide plate 10 can also move the components set on its top together. The cross arm lifter 14 can provide support for the rotating platform 13 under the support of the slide plate 10, and can push the rotating platform 13 to lift and adjust its height. The rotating platform 13 can provide support for the pallet 15, and can drive the pallet 15 to rotate.

[0024] In practical application, the patient can step onto the bed board 21 by stepping on the protective frame 6, support 7, and sliding plate 10 in sequence, and lie flat on the bed board 21 while ensuring that the head is resting on the pillow 38 for head and neck positioning. Then, the staff can control the first motor 4 as needed, causing the first motor 4 to drive the first gear 5 to rotate. Utilizing the rotational power of the first gear 5 and its meshing with the first rack 2, the patient moves along the first rack 2 in the X-axis direction. Simultaneously, the first motor 4 will drive the support frame 3 and all components above it, along with the patient, to move and adjust their position along the first rack 2 in the X-axis direction. This facilitates the patient's movement within the treatment room towards the radiotherapy equipment in the X-axis direction. Subsequently, the second motor 11 can be controlled as needed, causing the second motor 11 to drive the second gear 12 to rotate. Utilizing rotational power and meshing with the second rack 9, the device moves along the second rack 9 in the Y-axis direction under the support of the support 8. This allows the second motor 11 to drive the slide plate 10 and all components above it, along with the patient, to move and adjust their position in the Y-axis direction under the support of the bracket 7. Furthermore, the operator can control the crossarm lift 14 to adjust its height as needed, allowing the crossarm lift 14 to drive the rotating platform 13 and all components above it, along with the patient, to adjust its height under the support of the slide plate 10. Simultaneously, the operator can control the rotating platform 13 to rotate and adjust its position under the support of the crossarm lift 14, allowing the patient to move to the radiotherapy station for radiotherapy.

[0025] In a preferred embodiment of the present invention, a chassis 16 is slidably mounted on the Y-axis of the support plate 15, and a support plate 17 is slidably mounted on the X-axis of the chassis 16. A third rack 18 is fixed to the side of the support plate 17 near the chassis 16, and a third motor 19 is fixed below the chassis 16. The drive end of the third motor 19 is connected to a third gear 22, and the third gear 22 movably passes through the chassis 16 and meshes with the third rack 18. A fourth rack 20 is fixed to the side of the chassis 16 near the support plate 15, and a fourth motor 23 is fixed to the side of the support plate 15 near the cross lifter. The drive end of the fourth motor 23 movably passes through the support plate 15 and is connected to a fourth gear 62, and the fourth gear 62 meshes with the fourth rack 20. The bed board 21 is fixed on the support plate 17.

[0026] Specifically, the support plate 15 provides sliding support and guidance for the chassis 16 along the Y-axis, while the chassis 16 provides sliding support and guidance for the support plate 17 along the X-axis. The support plate 15 and chassis 16 provide space for the third gear 22 to pass through and rotate, and provide a passage for the third rack 18. The chassis 16 provides stable support for the third motor 19. The third motor 19 drives the third gear 22 to rotate using its drive end. The third gear 22, through meshing with the third rack 18, pushes the support plate 17 to move the bed board 21 along the X-axis under the support of the chassis 16. The support plate 15 provides stable support for the fourth motor 23. The fourth motor 23 drives the fourth gear 62 to rotate using its drive end. The fourth gear 62, through meshing, pushes the fourth rack 20 to move the chassis 16 along the Y-axis under the support of the support plate 15. Thus, the chassis 16 can move all the components and the patient on it together along the Y-axis to adjust their position.

[0027] In practical application, after the patient lies on the bed board 21, the operator can control the third motor 19 to rotate. The third motor 19 drives the third gear 22 to rotate, and the third gear 22, through meshing with the third rack 18, pushes the support plate 17 to move and adjust its position along the X-axis. At the same time, the operator can control the fourth motor 23 to rotate, and the fourth motor 23 drives the fourth gear 62 to rotate. The fourth gear 62, through rotational power and meshing with the fourth rack 20, pushes the chassis 16 to move and adjust its position along the Y-axis. This, in turn, adjusts the position of all components above it, including the bed board 21 and the patient, ultimately achieving high-precision alignment between the radiation port and the patient's target area. This achieves a simple and direct mechanical transmission structure, which improves the load capacity of the new treatment bed, eliminates the limitation of precision by a large number of sensors, enables rapid response to the patient's positioning needs, shortens positioning time, improves treatment efficiency, and realizes cost reduction and efficiency improvement of the treatment bed, reducing failure rate and operation training time.

[0028] In a preferred embodiment of the present invention, the trigger includes: A pillow board 37 is fixed to the side of the pillow cushion 38 near the pillow support 24; The opening 25 runs through the top of the pillow support 24; The first corrugated cylinder 26 is fixed at one end to the inner bottom wall of the pillow support 24, and at the other end is fixed to the pillow plate 37. The pressure contact part is located on the outside of the first corrugated cylinder 26 and is connected to the pillow support 24.

[0029] Specifically, the pillow board 37 is located above the opening 25. The pillow board 37 can provide support for the pillow pad 38. The pillow pad 38 is relatively soft and can improve the comfort of the patient's head and neck. The pillow pad 38 and the pillow board 37 are curved to conform to the curve of the human head and neck. The pillow support 24 can provide opening space for the opening 25. The opening 25 can provide passage and expansion space for the first corrugated cylinder 26 and the first spring 27. The first corrugated cylinder 26 can be squeezed, folded and contracted under the action of external force, and will rebound and return to its original position after the external force is removed.

[0030] The pressure contact components include: The first spring 27 is located on the outside of the first corrugated cylinder 26, with one end fixedly connected to the pillow support 24 and the other end fixedly connected to the pillow board 37; L-plate 28, one end of which is fixed to the outer side of the upper end of the first corrugated cylinder 26; The switch 29 is embedded and fixed in the inner bottom wall of the pillow support 24 and is located below the L plate 28.

[0031] Specifically, the first spring 27 can be compressed and stored under external force, and can cooperate with the first corrugated cylinder 26 to provide support for the pillow board 37. The pillow board 37 can be compressed and contracted by the external force applied by the patient's head, and the first corrugated cylinder 26 can drive the L-plate 28 to move together. The pillow support 24 can stably support the switch 29. The switch 29 will energize the multi-stage electric rod 30 after each press and release. The multi-stage electric rod 30 is reciprocating. After the switch 29 is pressed, the circuit controls the multi-stage electric rod 30 to reciprocate through relay logic, so that it can retract and reset after being fully extended. After the switch 29 is pressed, the circuit needs to detect a continuous pressing signal (such as 4-5 seconds) before it will perform the action. Short-term touch (accidental touch) will not respond.

[0032] The elastic force of the first spring 27 is less than the weight of an adult's head. When an adult with a lighter head may be unable to smoothly lower the L-plate 28 to trigger the switch, the patient can apply pressure by pushing the head with their neck as needed, thereby pushing the L-plate 28 to successfully trigger the switch 29. During radiotherapy, the patient usually lies flat or on their side on the treatment bed, with their head placed on the pillow pad 38 (the curvature of the pillow board 37 and the pillow pad 38 can conform to the curvature of the head and neck). Ensure that the back of the head and neck are in contact with the pillow pad 38 and are kept above the passage 39, with the face facing upward and the eyes naturally closed. This allows the pillow pad 38 to use its own curve to position the patient's head in conjunction with the passage 39, avoiding the problem of the patient's head being in different positions on the pillow pad 38.

[0033] The push-rub component includes: The tray 15 and the pad have a through passage 39 and a through groove 40 inside, and the through groove 40 is located at one end of the through passage 39 and is connected to the through passage 39. The multi-stage electric rod 30 has its fixed end connected to the inner wall of one end of the pillow support 24; Support rod 31 is connected to the telescopic end of multi-stage electric rod 30, has an internal cavity, and passes through opening 25; The second spring 32 is movably disposed in the internal cavity of the support rod 31, and one end is fixedly connected to the support rod 31. Link 33 is connected to the other end of the second spring 32, passes through the channel 39, and extends above the pillow cushion 38; Connecting plate 34 is fixed to one end of connecting rod 33; Sponge 36 is symmetrically fixed below connecting plate 34 by fixing components and is located in through groove 40; The multi-stage telescopic rod 63 is fixed inside the support rod 31, and its telescopic end is connected to the connecting rod 33 and located at the center of the second spring 32.

[0034] Specifically, the pillow board 37 extends through the pillow pad 38 to the top of the connecting plate 34, so that the connecting plate 34 can be pressed down by external force. Workers can disassemble the fixing components and remove the sponge 36 for cleaning and replacement as needed. The front of the pillow support 24 has a through-hole 61, which communicates with the through-hole 25 and corresponds to the position of the support rod 31, providing a passage for the extension and retraction ends of the support rod 31 and the multi-stage electric rod 30. The multi-stage electric rod 30 will extend and retract to its original position each time it is powered on, and will be de-energized after retraction to await the next power cycle. Electrically operated, the passageway 39 provides movement space for the connecting rod 33, the support rod 31, and the second spring 32. The multi-stage electric rod 30, supported by the pillow support 24, uses its telescopic end to support the support rod 31, allowing the support rod 31 to support the second spring 32 and the multi-stage telescopic rod 63, and providing space for the second spring 32 to extend and retract. The second spring 32 is in a stretched state, and the multi-stage telescopic rod 63 is in an extended state (stretched by the pillow cushion 38 and the connecting rod 33 using the rebound force of the first spring 27). The sponge 36 can be deformed under pressure, and... Figure 5 and Figure 10 As shown, the end of the sponge 36 near the connecting rod 33 can extend above the pillow cushion 38, allowing the sponge 36 to be moved above the pillow cushion 38 by the multi-stage electric rod 30 via the connecting plate 34, connecting rod 33, multi-stage telescopic rod 63 and support rod 31. The sponge 36 is absorbent and relatively soft, and can be deformed arbitrarily under the action of external force, and will recover when the external force is removed. The multi-stage telescopic rod 63 can extend and retract synchronously with the second spring 32 under the action of external force, and can prevent the second spring 32 from bending.

[0035] In practical application, when the patient lies on the bed board 21, the curved pillow with the head and neck in contact with the pillow pad 38 needs to be placed on the pillow pad 38. Under the action of external force, the pillow pad 38 will move the pillow board 37 downward together and squeeze the first spring 27 and the first corrugated cylinder 26 to retract and fold. At the same time, the pillow board 37 will press down the connecting plate 34 and the connecting rod 33 under the action of external force, so that the connecting plate 34 and the connecting rod 33 will move the sponge 36 downward together. At the same time, the second spring 32 will move downward and retract under the action of pressure and rebound force. When the first corrugated cylinder 26 retracts, it will move the L plate 28 downward together, so that the L plate 28 can contact the switch 29 and press down the switch 29, thereby preparing the trigger. When the patient's radiotherapy is completed and their head and neck are removed from the pillow 38 and the bed board 21 is lowered, the external force on the pillow 38 disappears. The first spring 27 then uses its rebound force to push the pillow board 37 back to its original position. The pillow board 37 then drives the first corrugated cylinder 26 to extend and return to its original position. Under the action of external force, the pillow 38 will stretch the second spring 32 upward through the connecting rod 33, and move the sponge 36 upward as well. At the same time, the first corrugated cylinder 26 will move the L-plate 28 upward and separate it from the switch 29, thereby triggering the switch 29 to supply power to the multi-stage electric rod 30. After the multi-stage electric rod 30 is energized, it will use its telescopic end to push the support rod 31, the second spring 32, and the multi-stage... The telescopic rod 63 moves horizontally together, and at the same time, the second spring 32 cooperates with the multi-stage telescopic rod 63 to use the thrust to pull the connecting rod 33 to move along the passage 39. Simultaneously, the connecting rod 33 will drive the sponge 36 to move together through the connecting plate 34, so that the sponge 36 can move onto the pillow 38. During the movement, the second spring 32 will use the rebound force to continuously pull the connecting rod 33, the connecting plate 34 and the sponge 36 downward. At the same time, the multi-stage telescopic rod 63 will retract synchronously, so that the sponge 36 can continuously contact the pillow surface of the pillow 38 under the push of the multi-stage electric rod 30. In this way, the sponge 36 can wipe and clean the pillow 38 in time after the patient uses it, so that it can be used by the next patient in a timely manner, thus solving the hygiene problem in a timely manner.

[0036] In a preferred embodiment of the present invention, the storage component includes: The first one-way valve 41 is disposed through the first bellows 26; The second corrugated cylinder 43 is fixed to the inner top wall of the pillow support 24 by a fixing component, and its lower end is connected to the other end of the L plate 28. Injection tube 44, one end of which passes through the first corrugated cylinder 26; The second one-way valve 45 is connected to the other end of the injection pipe 44 and to the lower end of the second bellows 43.

[0037] Specifically, the first corrugated cylinder 26 provides stable support for the first one-way valve 41. The first corrugated cylinder 26 is made of transparent material, allowing staff to observe the internal liquid level through the opening 25. The first one-way valve 41 only provides a channel for liquid to enter the first corrugated cylinder 26 and can be connected to a pipeline for conveying disinfectant, allowing disinfectant to be conveyed to the first corrugated cylinder 26 for storage through the first one-way valve 41. The upper end of the second corrugated cylinder 43 is fixed with a fixed plate 42, which is fixedly connected to the inner top wall of the pillow support 24 to stably support the second corrugated cylinder 43. The second corrugated cylinder 43 can be stretched and contracted under external force and can provide storage space for liquid. The injection pipe 44 provides a channel for disinfectant in the first corrugated cylinder 26 to enter the second one-way valve 45. The second one-way valve 45 only provides a channel for liquid in the injection pipe 44 to enter the second corrugated cylinder 43.

[0038] The nozzle guide includes: Pipe 46 has one end that passes through the lower end of the second corrugated cylinder 43 and is adjacent to the second one-way valve 45, and the other end that passes through the passage 39, the pillow plate 37 and the pillow pad 38 and extends into the through groove 40. The first nozzle 47 is fixed to the inner wall of the through groove 40 and connected to the other end of the pipe 46, and is located diagonally above the connecting plate 34. The first nozzle 47 has uniformly opened nozzle holes on the side away from the other end of the pipe 46; Multiple conical holes 35 are evenly distributed through the connecting plate 34.

[0039] Specifically, the drain pipe 46 provides a channel for the liquid in the second corrugated cylinder 43 to be discharged into the first nozzle 47. The cushion 38 and the pillow support 24 provide stable support for the first nozzle 47. The first nozzle 47 provides storage space for the liquid and provides opening space for the nozzle. The nozzle provides space for the liquid to be sprayed onto the connecting plate 34. The liquid sprayed onto the connecting plate 34 will flow into the conical hole 35 and penetrate through the conical hole 35 into the sponge 36, where it will be absorbed by the sponge 36.

[0040] In practical application, when the first corrugated cylinder 26 is squeezed and contracted, the disinfectant stored in the first corrugated cylinder 26 will be squeezed out to the inside of the injection tube 44. At the same time, the first corrugated cylinder 26 will pull down the lower end of the second corrugated cylinder 43 through the L plate 28, so that the second corrugated cylinder 43 will extend under the support of the fixed plate 42, and at the same time, the suction force will be generated to draw the disinfectant in the injection tube 44 into the second corrugated cylinder 43 for storage through the second one-way valve 45. When the first corrugated cylinder 26 extends and resets, it will move the lower end of the second corrugated cylinder 43 upwards through the L-plate 28. Under the support of the fixed plate 42, the second corrugated cylinder 43 will be squeezed and folded by external force. During the squeezing and folding process, the disinfectant stored inside will be squeezed out into the drain pipe 46. The disinfectant can pass through the drain pipe 46 into the first spray pipe 47 and fill the first spray pipe 47. It will then be discharged through the spray hole onto the connecting plate 34. The disinfectant can flow into the cone hole 35 and pass through the cone hole 35 to contact the sponge 36. The disinfectant can penetrate into the sponge 36 and be absorbed by the sponge 36. As the sponge 36 moves along the pillow surface of the pillow pad 38, it can work with the disinfectant to clean and disinfect the pillow pad 38, preventing cross-infection.

[0041] In a preferred embodiment of the present invention, the accommodating member includes: Storage cylinder 48 is fixed to the inner top wall of pillow support 24 and located below sponge 36 and first nozzle 47; Branch pipe 49, one end of which is installed through the second corrugated cylinder 43, and the other end of which is installed in the storage cylinder 48; The second nozzle 50 is fixed to the inner wall of the storage tank 48 and connected to the branch pipe 49. A nozzle hole is opened on the side away from the branch pipe 49.

[0042] Specifically, the storage tank 48 can provide support for the branch pipe 49 and the second spray pipe 50 under the support of the pillow support 24. The branch pipe 49 can provide a channel for the disinfectant in the second corrugated tank 43 to enter the second spray pipe 50, and the second spray pipe 50 can use the spray holes opened on it to provide a channel for the disinfectant to enter the storage tank 48 and be sprayed onto the wiping plate 57.

[0043] The rubbing element includes: Two toughness rods 53 are symmetrically fixed to the inner walls of both ends of the storage tank 48, and their shape is inclined wave-shaped. The bushing 54 is fixed to the end of the toughening rod 53 away from the storage tank 48; The swivel rod 55 is rotatably connected to the bushing 54 via a bearing and is located between the two flexible rods 53; The rotating roller 56 is fixed to the outside of the rotating rod 55; The wiping plate 57 is symmetrically fixed on the outside of the rotating roller 56, and the outside is evenly provided with semi-circular protrusions to cooperate with the rotating roller 56 and the tough rod 53 to support the wiping sponge 36 and keep the second spring 32 in a stretched state. The fixed-rotation component is located on the bottom wall inside the storage cylinder 48 and is connected to the rotating rod 55.

[0044] Specifically, a diagonal pressure rod 64 is fixed above the bushing 54. The upper end of the diagonal pressure rod 64 is connected to the pillow plate 37. When the pillow plate 37 moves downward, it will drive the diagonal pressure rod 64 to move downward together, so that the diagonal pressure rod 64 can push the bushing 54 downward under the action of external force. This allows the bushing 54 to push the toughness rod 53 downward and bend it. In turn, the bushing 54 can drive the rotating roller 56 and the wiping plate 57 to move downward together through the rotating rod 55. The bushing 54 can move up and down with the pillow plate 37 through the diagonal pressure rod 64. The toughness rod 53 has toughness and elasticity, and can bend and deform under the action of external force. It will rebound when the external force is removed, and it can provide support for the bushing 54. The bushing 54 can provide rotational support for the rotating rod 55. The rotating rod 55 can provide stable support for the rotating roller 56. The rotating roller 56 can stably support the wiping plate 57. The wiping plate 57 can cooperate with the semi-circular protrusion to scrape and clean the wiping surface of the sponge 36 under the action of external force.

[0045] Fixed-rotation components include: The fifth gear 58 is fixed to the outside of the rotating rod 55; The fifth rack 59 is symmetrically fixed to the inner bottom wall of the storage cylinder 48 and meshes with the fifth gear 58; The positioning rod 60 is fixed to the inner bottom wall of the storage cylinder 48 and contacts the outer side of the rotating rod 55 to limit the deformation of the tough rod 53 in the Y-axis direction.

[0046] Specifically, the container also includes: a drain pipe 51 is provided through the lower end of the storage cylinder 48, and a solenoid valve 52 is provided on the outside of the drain pipe 51 to control the flow of the drain pipe 51, and the drain pipe 51 passes through one end of the pillow support 24.

[0047] The storage cylinder 48 provides stable support for the fifth rack 59 and the positioning rod 60. The positioning rod 60, in cooperation with the fifth rack 59 and the fifth gear 58, provides a limiting function for the rotating rod 55. In turn, the rotating rod 55 provides a limiting and resisting function for the tough rod 53, preventing the tough rod 53 from bending radially. Furthermore, through the cooperation of the inclined pressure rod 64, the pillow plate 37 can only move up and down. Under the action of external force, the pillow plate 37 pushes the bushing 54 downward through the inclined pressure rod 64, so that the bushing 54 can drive the fifth gear 58 to move downward through the rotating rod 55. 5 will drive the wiping plate 57 to move downward together through the rotating roller 56. The fifth gear 58 can rotate during the lifting process by meshing with the fifth rack 59, so that the rotating rod 55, the rotating roller 56 and the wiping plate 57 can rotate together. Under the action of the pillow plate 37 and the inclined pressure rod 64, the sponge 36 and the wiping plate 57 can move downward together. The wiping plate 57 can contact and squeeze the sponge 36 during the rotation. The sponge 36 can be squeezed and deformed under the action of external force, so that the wiping plate 57 can rotate while squeezing the sponge 36.

[0048] In practical application, when the pillow board 37 is pressed downwards by the patient's head and neck, the pillow board 37 pushes the bushing 54 downwards via the inclined pressure rod 64, causing the bushing 54 to move along with the rotating rod 55. Simultaneously, the rotating rod 55 drives the rotating roller 56 and the fifth gear 58 downwards along the positioning rod 60, allowing the rotating roller 56 to move along with the wiping plate 57. During this movement, the bushing 54 pushes the flexible rod 53, causing it to bend under external force and the support of the storage cylinder 48. The rotating rod 55 then drives the fifth gear 58 downwards, causing it to roll along the fifth rack 59 during movement. This allows the fifth gear 58 to drive the rotating rod 55, rotating roller 56, and wiping plate 57 to rotate together under the support of the bushing 54. During rotation, the semi-circular protrusions intermittently scrape and clean the wiping surface of the sponge 36. When the patient separates from the pillow board 37 and the pillow board 37 moves upward and resets, the L plate 28 will squeeze the second corrugated cylinder 43 to contract and reset under the support of the fixed plate 42. This causes the second corrugated cylinder 43 to squeeze the disinfectant stored inside into the drain pipe 46 and the branch pipe 49. The disinfectant discharged into the branch pipe 49 will enter the second spray pipe 50 and be sprayed onto the wiping plate 57 through the spray holes on the second spray pipe 50. At the same time, it will fall into the storage tank 48 for storage, so that the disinfectant can be sprayed to wash the wiping plate 57, thereby providing convenience for automatically cleaning the wiping surface of the sponge 36. In addition, the staff can control the solenoid valve 52 to open according to the actual needs, so that the liquid and stains stored in the storage tank 48 can enter and be discharged to the outside through the drain pipe 51.

[0049] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
