Description

Technical Field

[0001] This invention relates to the field of disinfection device technology, and in particular to a closed-type intensive care unit disinfection device for human bodies. Background Technology

[0002] Intensive care refers to the centralized and intensive treatment and nursing care of various critically ill patients using advanced medical technologies and modern monitoring and rescue equipment. As patients in intensive care have weaker immune systems, it is necessary to disinfect the isolation gowns or clothing worn by medical staff to prevent infection of the patients when they enter and leave the intensive care unit with germs.

[0003] Existing technologies, such as the invention with publication number CN106075709B, disclose a closed-loop intensive care unit disinfection device, including a vertical rectangular frame. A moving mechanism is located on the lower surface of the vertical rectangular frame, a closed disinfection mechanism is located on the inner surface of the vertical rectangular frame, a display mechanism is located on the upper inner surface of the vertical rectangular frame, a foot disinfection mechanism is located on the lower inner surface of the vertical rectangular frame, and a controller is located on the side surface of the vertical rectangular frame. The controller is electrically connected to the closed disinfection mechanism, the display mechanism, the foot disinfection mechanism, and the hand disinfection mechanism. The advantages of this invention are its simple structure and strong practicality.

[0004] The inventors discovered during daily use that during the disinfection process, because medical staff directly step into the foot-shaped groove of the rectangular weighing plate, it is difficult to clean and disinfect foreign objects attached to the soles of the medical staff's shoes, thus making it difficult to fully disinfect the medical staff and reducing the practicality of the disinfection device.

[0005] This application provides another technical solution to this technical problem, aiming to provide medical professionals in the field with a variety of solutions to the problem. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies that require cleaning and disinfecting foreign objects attached to the soles of medical personnel's shoes, making it difficult to fully disinfect medical personnel. Therefore, this invention proposes a closed-loop intensive care unit disinfection device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a closed intensive care unit human body disinfection device, comprising a disinfection chamber, a door hinged to the surface of the disinfection chamber, an observation window fixedly connected inside the door, and an isolation plate fixedly connected inside the disinfection chamber; further comprising: a disinfection structure disposed on the surface of the disinfection chamber and the isolation plate for thoroughly disinfecting the protective clothing or garments of medical personnel, the disinfection structure comprising a first disinfection component for disinfecting the torso of medical personnel, a support component for supporting medical personnel, a second disinfection component for disinfecting the soles of medical personnel's shoes, and a third disinfection component for disinfecting the medical personnel's clothing. The system includes a cleaning component for cleaning the soles of medical staff's shoes, a waste discharge pipe for discharging waste liquid, and a support component including a roller for supporting medical staff. An auxiliary structure, located on the upper surface of the isolation plate, is used to fix the legs of medical staff. This auxiliary structure includes a fixing rod fixedly installed on the upper surface of the isolation plate, a mounting frame for limiting the movement of the medical staff's legs, and a sponge block for evenly discharging disinfectant. A braking structure, also located on the upper surface of the isolation plate, is used to quickly stop the roller's rotation. This braking structure includes a square frame fixedly installed on the upper surface of the isolation plate, protrusions and strips for braking, and a pedal for moving the protrusions.

[0008] The aforementioned components achieve the following effects: By operating the disinfection structure and utilizing the cooperation of the first disinfection component, the second disinfection component, the support component, and the cleaning component, the device can thoroughly disinfect the torso of medical personnel and clean and disinfect foreign objects from the soles of their shoes. This ensures that the disinfection device effectively disinfects the isolation gowns or clothing of medical personnel, greatly improving its practicality. The auxiliary structure restricts the position of the medical personnel's legs during disinfection, preventing situations where the soles of their shoes are not adequately disinfected due to the rotation of the rollers. This further ensures the normal operation of the disinfection structure. The braking structure allows for quick stopping of the rollers by stepping on a pedal if the medical personnel experience discomfort due to their feet during disinfection, ensuring their safety and improving the overall safety of the disinfection device.

[0009] Preferably, the first disinfection component includes a booster pump, which is fixedly installed on the outer wall of the disinfection chamber. The outlet end of the booster pump is connected to an outlet pipe, which penetrates the disinfection chamber. One end of the outlet pipe is connected to six first spray nozzles, the vertical central axes of the six first spray nozzles are located on the same circle, and the inlet end of the booster pump is connected to an inlet pipe.

[0010] The effect achieved by the above components is as follows: the booster pump draws in the disinfectant through the inlet pipe and delivers the disinfectant to the outlet pipe. The disinfectant flows through the outlet pipe and is discharged by the first spray nozzle. Since the vertical central axis of the six first spray nozzles is located on the same circle, the disinfectant will be sprayed out crosswise, thereby enabling thorough disinfection of the isolation gowns or clothing of medical personnel.

[0011] Preferably, the support assembly further includes a rotating ring, which is rotatably connected to the isolation plate and the roller. One end of the roller is rotatably connected to a connecting plate. A stepper motor is fixedly connected to the inner wall of the disinfection chamber, and a gear is fixedly connected to the output end of the stepper motor. A gear ring is fixedly connected to the lower surface of the rotating ring, and the gear ring meshes with the gear. A collection hopper is fixedly connected to the inner wall of the disinfection chamber, and a support ring is rotatably connected to the inner wall of the collection hopper. The support ring is fixedly connected to the rotating ring. The waste discharge pipe is connected to the lower end of the collection hopper and penetrates the disinfection chamber.

[0012] The effect achieved by the above components is as follows: when medical staff stand on the arc surface of the roller, the roller will support the medical staff. The output end of the stepper motor will rotate, which will drive the gear to rotate. The gear will drive the gear ring to rotate, which will drive the rotating ring to rotate. The rotating ring will drive the roller to roll along the sole of the medical staff's shoe, thereby preventing the roller from generating too much friction with the sole of the medical staff's shoe and causing discomfort to the medical staff.

[0013] Preferably, the second disinfection component includes a bracket, which is fixedly installed on the inner wall of the collection hopper. A rotating pipe is rotatably connected to the inner wall of the bracket. A branch pipe is rotatably connected to the arc surface of the rotating pipe. The branch pipe is connected to the discharge end of the booster pump and passes through the waste discharge pipe and the disinfection chamber. A hollow plate is connected to the upper end of the rotating pipe. A second spray pipe is connected to the arc surface of the hollow plate. A torsion spring is fitted on the arc surface of the rotating pipe. The two ends of the torsion spring are fixedly connected to the rotating pipe and the bracket, respectively. A transmission rod is fixedly connected to the arc surface of the rotating pipe. Three friction blocks are fixedly connected to the lower surface of the connecting plate. A friction rod is fixedly connected to the upper surface of the hollow plate.

[0014] The aforementioned components achieve the following effects: the disinfectant flows through the branch pipe into the hollow plate and is finally sprayed upwards by the second nozzle, thus rinsing and disinfecting the sole of the shoe. The rotation of the connecting plate drives the friction block to rotate. When the friction block contacts the friction rod, the friction block drives the friction rod to move. The movement of the friction rod drives the hollow plate to move. The movement of the hollow plate drives the rotating pipe and the second nozzle to rotate, allowing the second nozzle to spray disinfectant onto different parts of the sole for disinfection. The rotation of the rotating pipe twists the torsion spring and drives the transmission rod to rotate. When the transmission rod contacts the bracket, the bracket prevents the transmission rod from continuing to rotate, while the friction block continues to move with the connecting plate. Therefore, the friction block will disengage from the friction rod. At this time, the torsion spring will use its own torque to drive the hollow plate to rotate in the opposite direction, thus causing the second nozzle to rotate in the opposite direction, thereby preventing the disinfectant sprayed from the second nozzle from being blocked by the roller and the round pipe.

[0015] Preferably, the frictional force between the friction block and the friction rod is greater than the torque of the torsion spring.

[0016] The effect achieved by the above components is that by making the friction force between the friction block and the friction rod greater than the torque of the torsion spring, it can be ensured that the friction block can normally drive the friction rod to move a certain distance.

[0017] Preferably, the cleaning assembly includes a mounting rod rotatably connected to a rotating ring. A circular tube is fitted onto the arc surface of the mounting rod. Two grooves are formed on the arc surface of the circular tube. Several bristles are fixedly connected to the inner wall of the grooves on the circular tube. A support arm is fixedly connected to the lower surface of the connecting plate. Two slots are formed on the arc surface of the circular tube. The size of the slots is adapted to the size of the support arm.

[0018] The aforementioned components achieve the following effects: the rotation of the rotating ring drives the mounting rod to rotate, which in turn drives the round tube to rotate. The rotation of the round tube causes the bristles to slide along the soles of the medical staff's shoes, thereby brushing the soles and effectively removing foreign objects attached to them. After the bristles have been working for a certain period of time, foreign objects tend to accumulate on their surface. At this point, rotating the mounting rod causes the round tube to rotate from a horizontal to a vertical position. Then, the round tube rotates 180 degrees along the arc surface of the mounting rod. After the mounting rod is returned to its original position, the support arm engages with the slot, providing support for the round tube. This reduces the gap between the rollers, preventing the medical staff's feet from getting stuck in the gaps when walking. Furthermore, it also prevents the rotation of the round tube from affecting the normal operation of the bristles.

[0019] Preferably, a slider is slidably connected to the surface of the fixed rod, a connecting rod is fixedly connected to the surface of the slider, the connecting rod is fixedly connected to the mounting frame, the sponge block is engaged with the mounting frame, a telescopic tube is connected to the surface of the mounting frame, the telescopic tube is connected to the branch pipe, and a screw is threadedly connected to the surface of the slider, the screw passing through the slider and abutting against the surface of the fixed rod.

[0020] The aforementioned components achieve the following effects: During the disinfection process, the disinfectant flowing through the branch pipe can also flow into the telescopic pipe. The disinfectant then flows out of the mounting frame and is absorbed by the sponge block. As the disinfectant accumulates, some will seep out from the sponge block, thus disinfecting the clothing worn by medical personnel's legs. This prevents disinfection blind spots caused by the mounting frame obstructing the view. The sponge block also prevents the mounting frame from pressing against the legs of medical personnel. When the height of the mounting frame needs to be adjusted, the screw is rotated to disengage from the fixed rod. Then, the mounting frame is pulled, and the connecting rod, moving with the frame, causes the slider to slide. The fixed rod restricts the slider's sliding path. Once the mounting frame reaches the appropriate height, the screw is rotated in the opposite direction. When the screw again presses against the surface of the fixed rod, it restricts the slider's position, thus limiting the mounting frame's position. Adjusting the position of the mounting frame allows for adjustment of the sponge block's position, making it convenient to set the mounting frame's position according to the height of medical personnel and improving the flexibility of using the auxiliary structure.

[0021] Preferably, the connecting rod has a cylindrical structure, and a retaining plate is engaged with the arc surface of the connecting rod. The retaining plate is slidably connected to the mounting frame, and a cloth strip is fixedly connected to the surface of the retaining plate. The cloth strip is slidably connected to the mounting frame.

[0022] The effect achieved by the above components is as follows: the plate slides along the surface of the mounting frame until it is locked onto the arc surface of the connecting rod. At this point, the plate restricts the position of the fabric strip, thereby improving the restriction effect on the legs of medical staff.

[0023] Preferably, the inner wall of the frame is slidably connected to the pedal, the protrusion is fixedly installed on the lower surface of the pedal, the upper surface of the connecting plate is fixedly connected to the protruding strip, an insert plate is slidably connected inside the frame, the vertical cross-section of the insert plate is "L" shaped, the long arm of the insert plate and the surface of the pedal are both provided with inclined surfaces, a leaf spring is fixedly connected to the surface of the short arm of the insert plate, the other end of the leaf spring is fixedly connected to the frame, a guide rod is slidably passed through the surface of the pedal, and the two ends of the guide rod are fixedly connected to the isolation plate and the frame respectively.

[0024] The aforementioned components achieve the following effect: During the disinfection process, when medical staff experience discomfort in their feet due to the rotation of the roller, they can step on the pedal. The pedal causes the protrusion to slide downwards. When the protrusion is engaged between adjacent convex strips, it restricts the position of the convex strips, thus preventing the connecting plate from continuing to rotate, and consequently, preventing the roller from continuing to rotate. At this point, the pedal contacts the isolation plate. As the pedal slides downwards, the inclined surface of the sliding plate presses against the inclined surface of the insert plate. The insert plate then slides along the frame and stretches the leaf spring. The leaf spring is in a stretched state. When the pedal contacts the isolation plate, the inclined surface of the pedal disengages from the inclined surface of the insert plate. The leaf spring then contracts, and the lower surface of the insert plate contacts the pedal. At this point, the insert plate prevents the pedal from sliding upwards, thus ensuring the protrusion's limiting effect on the convex strips.

[0025] Preferably, a spring is fixedly connected to the inner wall of the frame, and the other end of the spring is fixedly connected to the pedal.

[0026] The effect achieved by the above components is as follows: when the spring contracts, it will cause the pedal to slide upward, thereby causing the convex strip to disengage from the convex block, and then the roller can rotate normally, and the spring will achieve the function of automatically resetting the pedal.

[0027] In summary, the beneficial effects of the present invention are as follows:

[0028] 1. In this invention, by operating the disinfection structure and with the cooperation of the first disinfection component, the second disinfection component, the support component, and the cleaning component, it is possible to not only thoroughly disinfect the torso of medical personnel, but also clean and disinfect foreign objects on the soles of their shoes, thus enabling the disinfection device to thoroughly disinfect the isolation gowns or clothing of medical personnel, greatly improving the practicality of the disinfection device.

[0029] 2. In this invention, by operating the auxiliary structure, the position of the medical staff's legs can be restricted during the disinfection process, thereby preventing the medical staff from being unable to be fully disinfected due to the rotation of the roller during the disinfection process, and further ensuring that the disinfection structure can work normally.

[0030] 3. In this invention, by operating the braking structure, when medical staff experience discomfort in their feet due to the rotation of the roller during the disinfection process, they can quickly stop the roller from rotating by stepping on the pedal, thereby ensuring the safety of medical staff and improving the safety of the disinfection device.

[0045] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0046] Reference Figure 1As shown, the present invention provides a technical solution: a closed intensive care unit human body disinfection device, including a disinfection chamber 1, a door 2 hinged to the surface of the disinfection chamber 1, an observation window 3 fixedly connected inside the door 2, and an isolation plate 7 fixedly connected inside the disinfection chamber 1. It also includes: a disinfection structure 4 disposed on the surfaces of the disinfection chamber 1 and the isolation plate 7 for thoroughly disinfecting the isolation gowns or clothing of medical personnel. The disinfection structure 4 includes a first disinfection component 41 for disinfecting the torso of medical personnel, a support component 42 for supporting medical personnel, a second disinfection component 43 for disinfecting the soles of medical personnel's shoes, and a cleaning component for cleaning the soles of medical personnel's shoes. 44. A waste discharge pipe 45 for discharging waste liquid; a support assembly 42 including a roller 427 for supporting medical personnel; an auxiliary structure 5 disposed on the upper surface of the isolation plate 7 for fixing the legs of medical personnel, the auxiliary structure 5 including a fixing rod 51 fixedly installed on the upper surface of the isolation plate 7, a mounting frame 54 for limiting the legs of medical personnel, and a sponge block 55 for evenly discharging disinfectant; a braking structure 6 disposed on the upper surface of the isolation plate 7 for quickly stopping the rotation of the roller 427, the braking structure 6 including a square frame 61 fixedly installed on the upper surface of the isolation plate 7, a protrusion 63 and a protrusion 64 for braking, and a pedal 62 for moving the protrusion 63.

[0047] The following section will explain the specific configuration and function of its disinfection structure 4, auxiliary structure 5, and braking structure 6.

[0048] Reference Figure 2-6As shown in this embodiment: the first disinfection component 41 includes a booster pump 411, which is fixedly installed on the outer wall of the disinfection chamber 1. The outlet end of the booster pump 411 is connected to an outlet pipe 412, which penetrates the disinfection chamber 1. One end of the outlet pipe 412 is connected to six first spray pipes 413, whose vertical central axes are located on the same circle. The inlet end of the booster pump 411 is connected to an inlet pipe 414. The booster pump 411 draws disinfectant through the inlet pipe 414 and delivers the disinfectant to the outlet pipe 412. The disinfectant flows through the outlet pipe 412 and is discharged by the first spray pipes 413. Since the vertical central axes of the six first spray pipes 413 are located on the same circle, the disinfectant is sprayed out crosswise, thereby fully disinfecting the isolation gowns or clothing of medical personnel. The support assembly 42 also includes a rotating ring 421, which is rotatably connected to the isolation plate 7 and the roller 427. A connecting plate 428 is rotatably connected to one end of the roller 427. A stepper motor 422 is fixedly connected to the inner wall of the disinfection chamber 1, and a gear 423 is fixedly connected to the output end of the stepper motor 422. A gear ring 424 is fixedly connected to the lower surface of the rotating ring 421, and the gear ring 424 meshes with the gear 423. A collection hopper 425 is fixedly connected to the inner wall of the disinfection chamber 1, and a support ring 426 is rotatably connected to the inner wall of the collection hopper 425. The support ring 426 and the rotating ring 421 are connected to each other. 1. Fixed connection: The waste discharge pipe 45 is connected to the lower end of the collection hopper 425. The waste discharge pipe 45 passes through the disinfection chamber 1. Medical staff stand on the arc surface of the roller 427. At this time, the roller 427 will support the medical staff. The output end of the stepper motor 422 rotates, which drives the gear 423 to rotate. The gear 423 rotates, which drives the gear ring 424 to rotate. The gear ring 424 rotates, which drives the rotating ring 421 to rotate. The rotating ring 421 rotates, which drives the roller 427 to roll along the sole of the medical staff's shoes, thereby preventing the roller 427 from generating too much friction with the sole of the medical staff's shoes and causing discomfort to the medical staff.

[0049] Reference Figure 7 , Figure 8 and Figure 9As shown in this embodiment: the second disinfection component 43 includes a bracket 431, which is fixedly installed on the inner wall of the collection hopper 425. A rotating pipe 432 is rotatably connected to the inner wall of the bracket 431. A branch pipe 433 is rotatably connected to the arc surface of the rotating pipe 432. The branch pipe 433 is connected to the discharge end of the booster pump 411 and passes through the waste discharge pipe 45 and the disinfection chamber 1. A hollow plate 434 is connected to the upper end of the rotating pipe 432. A second spray pipe 435 is connected to the arc surface of the hollow plate 434. A torsion spring 437 is fitted onto the arc surface of the rotating pipe 432. The two ends of the torsion spring 437 are fixedly connected to the rotating pipe 432 and the bracket 431, respectively. A transmission rod 436 is fixedly connected to the arc surface of the rotating pipe 432. Three friction blocks 439 are fixedly connected to the lower surface of the connecting plate 428. A friction rod 438 is fixedly connected to the upper surface of the hollow plate 434. The disinfectant flows through the branch pipe 433 into the hollow plate 434 and is finally sprayed upwards by the second spray pipe 435, thus rinsing and disinfecting the shoe soles. The rotating connecting plate 428 causes the friction block 439 to rotate. When the friction block 439 contacts the friction rod 438, it moves the friction rod 438. The movement of the friction rod 438 moves the hollow plate 434, which in turn moves the rotating pipe 432 and the second spray pipe 435. This allows the second spray pipe 435 to spray disinfectant onto different parts of the shoe sole. The rotation of the rotating pipe 432 twists the torsion spring 437 and drives the transmission rod 436 to rotate. When the transmission rod 436 contacts the bracket 431, the bracket 431 will prevent the transmission rod 436 from continuing to rotate, while the friction block 439 will continue to move with the connecting plate 428. Therefore, the friction block 439 will disengage from the friction rod 438. At this time, the torsion spring 437 will use its own torque to drive the hollow plate 434 to rotate in the opposite direction, thereby causing the second nozzle 435 to rotate in the opposite direction, thus preventing the disinfectant sprayed from the second nozzle 435 from being blocked by the roller 427 and the round tube 442. The frictional force between the friction block 439 and the friction rod 438 is greater than the torque of the torsion spring 437. By making the frictional force between the friction block 439 and the friction rod 438 greater than the torque of the torsion spring 437, it can be ensured that the friction block 439 can normally drive the friction rod 438 to move a certain distance.

[0050] Reference Figure 9 and Figure 10As shown in this embodiment: the cleaning component 44 includes a mounting rod 441, which is rotatably connected to a rotating ring 421. A circular tube 442 is fitted onto the arc surface of the mounting rod 441. Two grooves are formed on the arc surface of the circular tube 442. Several bristles 443 are fixedly connected to the inner wall of the grooves on the circular tube 442. A support arm 444 is fixedly connected to the lower surface of the connecting plate 428. Two slots 445 are formed on the arc surface of the circular tube 442. The size of the slots 445 is adapted to the size of the support arm 444. The rotation of the rotating ring 421 causes the mounting rod 441 to rotate, which in turn causes the round tube 442 to rotate. The rotation of the round tube 442 causes the bristles 443 to slide along the soles of the medical staff's shoes, thus brushing the soles and effectively removing foreign matter. After the bristles 443 have been working for a certain period, foreign matter may accumulate on their surface. At this point, rotating the mounting rod 441 causes the round tube 442 to rotate from a horizontal to a vertical position. Rotate the round tube 442 180 degrees along the arc surface of the mounting rod 441, and then rotate the mounting rod 441 back to its original position. At this time, the support arm 444 will engage with the slot 445, and the support arm 444 will support the round tube 442, thereby reducing the gap between the rollers 427 and preventing the feet of medical staff from getting stuck in the gap between the rollers 427 when walking. In addition, it can also prevent the rotation of the round tube 442 from affecting the normal operation of the bristles 443.

[0051] Reference Figure 11As shown in this embodiment: a slider 52 is slidably connected to the surface of the fixed rod 51, a connecting rod 53 is fixedly connected to the surface of the slider 52, the connecting rod 53 is fixedly connected to the mounting frame 54, a sponge block 55 is snapped into the mounting frame 54, a telescopic tube 56 is connected to the surface of the mounting frame 54, the telescopic tube 56 is connected to the branch pipe 433, and a screw 59 is threadedly connected to the surface of the slider 52. The screw 59 passes through the slider 52 and abuts against the surface of the fixed rod 51. During the disinfection process, the disinfectant flowing through the branch pipe 433 can also flow into the telescopic tube 56. Afterwards, the disinfectant will flow out from the mounting frame 54 and be absorbed by the sponge block 55. As the disinfectant accumulates, some disinfectant will seep out from the sponge block 55. At this time, the disinfectant can disinfect the clothing on the legs of medical staff, thereby preventing leakage caused by the mounting frame 54 blocking the flow. In the absence of disinfection dead corners, the sponge block 55 can also prevent the mounting frame 54 from pressing against the legs of medical staff. When it is necessary to adjust the height of the mounting frame 54, rotate the screw 59 to disengage the screw 59 from the fixing rod 51, and then pull the mounting frame 54. The connecting rod 53 will move the slider 52 with the help of the mounting frame 54. The fixing rod 51 will limit the sliding path of the slider 52. When the mounting frame 54 slides to the appropriate height, rotate the screw 59 in the opposite direction. When the screw 59 abuts against the surface of the fixing rod 51 again, the screw 59 will limit the position of the slider 52, thereby limiting the position of the mounting frame 54. By adjusting the position of the mounting frame 54, the position of the sponge block 55 can be adjusted, which makes it convenient to set the position of the mounting frame 54 according to the height of medical staff, thus improving the flexibility when using the auxiliary structure 5. The connecting rod 53 has a cylindrical structure. The arc surface of the connecting rod 53 is engaged with a clamping plate 57. The clamping plate 57 is slidably connected to the mounting frame 54. A cloth strip 58 is fixedly connected to the surface of the clamping plate 57. The cloth strip 58 is slidably connected to the mounting frame 54. The clamping plate 57 slides along the surface of the mounting frame 54 until the clamping plate 57 is engaged with the arc surface of the connecting rod 53. At this time, the clamping plate 57 achieves the function of restricting the position of the cloth strip 58, thereby improving the restriction effect on the legs of medical staff.

[0052] Reference Figure 12 and Figure 13As shown in this embodiment: the inner wall of the frame 61 is slidably connected to the pedal 62; the protrusion 63 is fixedly installed on the lower surface of the pedal 62; the upper surface of the connecting plate 428 is fixedly connected to the protrusion 64; an insert plate 65 is slidably connected inside the frame 61; the vertical cross-section of the insert plate 65 is "L"-shaped; both the long arm of the insert plate 65 and the surface of the pedal 62 are provided with inclined surfaces; a leaf spring 66 is fixedly connected to the surface of the short arm of the insert plate 65; the other end of the leaf spring 66 is fixedly connected to the frame 61; a guide rod 68 slides through the surface of the pedal 62; both ends of the guide rod 68 are fixedly connected to the isolation plate 7 and the frame 61, respectively. During the disinfection process, when medical staff experience discomfort in their feet due to the rotation of the roller 427, they can step on the pedal 62. At this time, the pedal 62 will drive the protrusion 63 to move towards... As the pedal slides downwards, when the protrusion 63 is engaged between adjacent protrusions 64, the protrusion 63 restricts the position of the protrusions 64, thereby preventing the connecting plate 428 from continuing to rotate, and consequently preventing the roller 427 from continuing to rotate. At this time, the pedal 62 will contact the isolation plate 7. When the pedal 62 slides downwards, the inclined surface of the slide plate will press against the inclined surface of the insert plate 65. At this time, the insert plate 65 will slide along the inside of the frame 61 and stretch the leaf spring 66. At this time, the leaf spring 66 is in a stretched state. When the pedal 62 contacts the isolation plate 7, the inclined surface of the pedal 62 will disengage from the inclined surface of the insert plate 65. At this time, the leaf spring 66 begins to contract, and the lower surface of the insert plate 65 will contact the pedal 62. At this time, the insert plate 65 prevents the pedal 62 from sliding upwards, thereby ensuring the limiting effect of the protrusion 63 on the protrusions 64. A spring 67 is fixedly connected to the inner wall of the frame 61. The other end of the spring 67 is fixedly connected to the pedal 62. When the spring 67 contracts, it will drive the pedal 62 to slide upward, thereby causing the protrusion 64 to disengage from the protrusion 63. Then the roller 427 can rotate normally, and the spring 67 achieves the function of automatically resetting the pedal 62.

[0053] Detailed Instructions for Use: When disinfecting medical personnel, first connect the inlet pipe 414 to the external disinfectant container, then close the hatch 2 and remove the clamping plate 57 from the arc surface of the connecting rod 53. The medical personnel then stand on the arc surface of the roller 427, which will support them. The medical personnel's legs should then contact the sponge block 55. Next, slide the clamping plate 57 along the surface of the mounting frame 54 again until it is locked onto the arc surface of the connecting rod 53. At this point, the clamping plate 57 restricts the position of the fabric tape 58, thus limiting the position of the medical personnel's legs. Because the connecting rod 53 has a cylindrical structure, the clamping plate 57 can more easily lock onto its arc surface. Then, start the booster pump 411 and the stepper motor 42. 2. The booster pump 411 draws disinfectant through the inlet pipe 414 and delivers it to the outlet pipe 412 and branch pipe 433. The disinfectant flows through the outlet pipe 412 and is discharged by the first spray pipe 413. Since the vertical central axes of the six first spray pipes 413 are on the same circle, the disinfectant is sprayed crosswise, thus thoroughly disinfecting the isolation gowns or clothing of medical personnel. At the same time, the disinfectant flows through the branch pipe 433 into the hollow plate 434 and is finally sprayed upward by the second spray pipe 435, rinsing and disinfecting the soles of shoes. The output of the stepper motor 422 rotates, which drives the gear 423 to rotate. The gear 423 rotates, which drives the gear ring 424 to rotate. The gear ring 424 rotates, which drives the rotating ring 421 to rotate. The movement of the roller 427 causes it to rotate. Since the medical staff's legs are restricted, the roller 427 rolls along the sole of their shoe, preventing excessive friction and discomfort. The rotation of the roller 427 causes the connecting plate 428 to rotate, which in turn causes the friction block 439 to rotate. When the friction block 439 contacts the friction rod 438, the friction between them exceeds the torque of the torsion spring 437, causing the friction block 439 to move the friction rod 438. This movement of the friction rod 438 then moves the hollow plate 434, which in turn rotates the rotating pipe 432 and the second nozzle 435, thus causing the second nozzle 435 to rotate. The device 35 can spray disinfectant onto different parts of the shoe sole for disinfection. The rotation of the rotating tube 432 will twist the torsion spring 437 and drive the transmission rod 436 to rotate. When the transmission rod 436 contacts the bracket 431, the bracket 431 will prevent the transmission rod 436 from continuing to rotate, while the friction block 439 will continue to move with the connecting plate 428. Therefore, the friction block 439 will disengage from the friction rod 438. At this time, the torsion spring 437 will use its own torque to drive the hollow plate 434 to rotate in the opposite direction, thereby causing the second spray tube 435 to rotate in the opposite direction. This prevents the disinfectant sprayed from the second spray tube 435 from being blocked by the roller 427 and the round tube 442. Simultaneously, the rotation of the rotating ring 421 will drive the mounting rod 441 to rotate, and the rotation of the mounting rod 441 will drive the round tube 442 to rotate.The rotation of the round tube 442 causes the bristles 443 to slide along the soles of the medical staff's shoes, thus brushing the soles and better removing foreign objects attached to them. After the bristles 443 have been working for a certain period of time, foreign objects may accumulate on their surface. At this time, rotating the mounting rod 441 will cause the round tube 442 to rotate from a horizontal position to a vertical position. Then, the round tube 442 will rotate 180 degrees along the arc surface of the mounting rod 441. After that, the mounting rod 441 will be rotated back to its original position. At this time, the support arm 444 will engage with the slot 445, and the support arm 444 will support the round tube 442, thereby reducing the gap between the rollers 427 and preventing the medical staff's feet from getting stuck in the gap between the rollers 427 when walking. Furthermore, it prevents the rotation of the round tube 442 from affecting the normal operation of the brush bristles 443. Waste liquid generated during disinfection flows into the support ring 426 through the gap between the roller 427 and the round tube 442. The waste liquid is then discharged through the collection hopper 425 and the waste discharge pipe 45. When the brush bristles 443 at the lower end of the round tube 442 are aligned with the second spray pipe 435, the disinfectant sprayed from the second spray pipe 435 can rinse the brush bristles 443, thus cleaning the foreign matter accumulated on the surface of the brush bristles 443. Since the brush bristles 443 are located in the groove on the arc surface of the round tube 442, the disinfectant rinsing the brush bristles 443 bounces downwards and drips after impacting the inner wall of the groove, thus preventing secondary contamination of the medical staff's shoes by the disinfectant rinsing the brush bristles 443.

[0054] During the disinfection process, the disinfectant flowing through branch pipe 433 can also flow into telescopic pipe 56. The disinfectant then flows out from mounting frame 54 and is absorbed by sponge block 55. As the disinfectant accumulates, some will seep out from sponge block 55. At this point, the disinfectant can disinfect the clothing on the legs of medical staff, thus preventing disinfection dead zones caused by mounting frame 54 obstructing the view. Sponge block 55 also prevents mounting frame 54 from pressing against the legs of medical staff. When the height of mounting frame 54 needs to be adjusted, rotate screw 59 to disengage screw 59 from fixing rod 51, then pull... The movable mounting frame 54 and the connecting rod 53 move together to drive the slider 52 to slide. The fixed rod 51 restricts the sliding path of the slider 52. When the mounting frame 54 slides to a suitable height, the screw 59 is rotated in the opposite direction. When the screw 59 abuts against the surface of the fixed rod 51 again, the screw 59 restricts the position of the slider 52, thereby restricting the position of the mounting frame 54. The position of the sponge block 55 can be adjusted by adjusting the position of the mounting frame 54, which makes it convenient to set the position of the mounting frame 54 according to the height of medical staff, thus improving the flexibility of using the auxiliary structure 5.

[0055] During the disinfection process, if medical staff experience discomfort in their feet due to the rotation of roller 427, they can step on pedal 62. Pedal 62 will cause protrusion 63 to slide downwards. When protrusion 63 is engaged between adjacent protrusions 64, it restricts the position of protrusions 64, thus preventing the connecting plate 428 from continuing to rotate, and consequently preventing the roller 427 from continuing to rotate. At this point, pedal 62 will contact the isolation plate 7. As pedal 62 slides downwards, the inclined surface of the sliding plate will press against the inclined surface of the insert plate 65. The insert plate 65 will then slide along the frame 61 and stretch the leaf spring 66. The leaf spring 66 is in a stretched state. When pedal 62 slides along the arc surface of guide rod 68, it will also stretch spring 67. After pedal 62 contacts the isolation plate 7, the inclined surface of pedal 62 will disengage from the inclined surface of insert plate 65. When leaf spring 66 retracts, the lower surface of insert plate 65 contacts pedal 62. At this time, insert plate 65 prevents pedal 62 from sliding upward, thus ensuring the limiting effect of protrusion 63 on protrusion 64. When roller 427 needs to rotate normally, pull the two insert plates 65 in the direction away from each other, so that insert plate 65 is disengaged from pedal 62 again. At this time, spring 67 retracts and drives pedal 62 to slide upward, thus disengaging protrusion 64 from protrusion 63. After that, roller 427 can rotate normally. Spring 67 will use its own elasticity to prevent pedal 62 from sliding downward due to its own weight. Therefore, spring 67 can both automatically reset pedal 62 and prevent protrusion 63 from contacting protrusion 64 when pedal 62 slides down during normal operation of roller 427.
