[0001] This invention relates to the field of medical device technology, specifically to a hand disinfection device for intensive care nursing. Background Technology
[0002] As the core area for treating critically ill patients in hospitals, the intensive care unit (ICU) is where patients generally have low immunity and undergo frequent invasive procedures. Hands are the most direct medium of contact between medical staff and patients, and the effectiveness of hand disinfection directly determines the success or failure of infection control in the ICU. Before and after nursing or medical procedures, medical staff often need to thoroughly clean and disinfect their hands to prevent cross-infection. Traditional hand disinfection is often done manually, which is not only cumbersome but also prone to leaving blind spots and resulting in bacteria residue on the hands. Summary of the Invention
[0003] This invention opens the pores of the palms by preheating with hot air. At this time, the atomized disinfectant can penetrate into the superficial tissue of the skin through the open pores, preventing blind spots in disinfection and killing pathogens hidden on the surface and in the superficial layer, reducing the risk of bacterial residue. At the same time, the atomized disinfectant can evenly cover all parts of the hands, promoting the killing of bacteria or viruses on the skin surface and in the pores.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a hand disinfection device for intensive care nursing, comprising a cleaning tank, a transparent plate installed on one side of the cleaning tank, two sets of rubber rings opened inside the transparent plate, a partition installed inside the cleaning tank, two sets of hand-locking devices sliding on the upper end of the partition, a limit plate sliding on one side of the two sets of hand-locking devices, two sets of electric push rods sliding on the lower end of the partition, and the output ends of the two sets of electric push rods extending to the upper end of the partition and connecting with the hand-locking devices through two sets of guide grooves opened on the surface of the partition; The cleaning tank is equipped with a three-way connecting valve. One end of the three-way connecting valve is connected to a hot air blower, and a stopcock valve is installed inside the three-way connecting valve. The other end of the three-way connecting valve is connected to two sets of first nozzles. A branch end of the three-way connecting valve is connected to a storage tank. A conveying pipe is connected to one side of the storage tank, and two sets of second nozzles are connected to the other end of the conveying pipe. The outer side of the conveying pipe is connected to two sets of clamping devices, and the interior of the two sets of clamping devices is hollow, with multiple sets of through holes on the outer side of each set of clamping devices.
[0005] Preferably, one end of the three-way connecting valve is fixedly connected to an air supply pipe, the other end of the air supply pipe extends through the cleaning tank to the outside of the cleaning tank and is connected to the hot air, and the other end of the three-way connecting valve is fixedly connected to a connecting pipe A.
[0006] Preferably, a first bracket is installed at the upper end of the cleaning tank, and two sets of first nozzles are installed inside the first bracket. The other end of the connecting pipe A extends through the cleaning tank and into the cleaning tank to connect with the two sets of first nozzles.
[0007] Preferably, one end of the limiting plate is fixedly connected to two sets of springs, the other end of the two sets of springs is fixedly connected to the inner wall of the cleaning tank, and the limiting plate is slidably connected to the inner wall of the cleaning tank. A rack is fixedly connected to one side of the limiting plate.
[0008] Preferably, one end of the plug valve is fixedly connected to a valve stem, the other end of the valve stem extends outward through the three-way connecting valve, and the other end of the valve stem is fixedly connected to a gear, which meshes with a rack.
[0009] Preferably, a connecting pipe B is fixedly connected to one branch end of the three-way connecting valve, and the other end of the connecting pipe B is connected to the storage tank. A second bracket is connected to one side of the first bracket, and two sets of second nozzles are installed inside the second bracket.
[0010] Preferably, a rotating shaft is rotatable between the two sets of electric push rods, one end of which extends through the cleaning tank to the outside and is connected to a motor, and the rotating shaft is threaded.
[0011] Preferably, a connecting plate is threadedly connected to the threaded part of the rotating shaft, and the two ends of the connecting plate are connected to two sets of electric actuators.
[0012] Preferably, a branch pipe is fixedly connected to the outside of the conveying pipe, and two sets of flexible hoses are connected to the other end of the branch pipe. The other ends of the two sets of flexible hoses are respectively connected to two sets of clamping devices.
[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention uses hot air preheating to open the pores of the palms. At this time, the atomized disinfectant can penetrate into the superficial tissue of the skin through the open pores, preventing blind spots in disinfection and killing pathogens hidden on the surface and in the superficial layers, reducing the risk of bacterial residue. At the same time, the atomized disinfectant can evenly cover all parts of the hands. In conjunction with the open pores, the disinfectant not only stays on the skin surface but also penetrates to a deeper layer, promoting the killing of bacteria or viruses on the skin surface and in the pores, resulting in better disinfection effect.
[0014] This invention utilizes multiple sets of through-holes on the outside of the hand-clamping device to continuously exude disinfectant, ensuring precise replenishment of disinfectant during the rubbing and washing process between the fingers. This guarantees that the finger gaps are always covered with sufficient disinfectant during the rubbing process, preventing incomplete disinfection caused by the reciprocating movement of the two sets of hand-clamping devices. At the same time, the disinfectant can penetrate into the superficial layer of the skin through the open pores between the fingers, killing not only pathogenic microorganisms on the surface of the finger gaps but also eliminating deep-seated bacteria and viruses hidden in the pores between the fingers, significantly improving the thoroughness of disinfection.
[0015] This invention prevents the cold or sticky feeling caused by damp hands after disinfection through automatic drying, and the warm drying can reduce skin irritation, thereby protecting the skin barrier of medical staff's hands. At the same time, it prevents residual wet disinfectant from affecting subsequent operations such as wearing gloves or holding instruments. The hot air dries the hands quickly, preventing residual liquid from creating a damp environment that breeds bacteria and leads to the risk of secondary contamination. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0019] Reference Figures 1-11 The present invention provides a hand disinfection device for intensive care nursing, including a cleaning tank 1, a transparent plate 2 installed on one side of the cleaning tank 1, two sets of rubber rings 3 opened inside the transparent plate 2, a partition 19 installed inside the cleaning tank 1, two sets of hand-holding devices 4 sliding on the upper end of the partition 19, a limit plate 5 sliding on one side of the two sets of hand-holding devices 4, and two sets of electric push rods 21 sliding on the lower end of the partition 19. The output ends of the two sets of electric push rods 21 extend to the upper end of the partition 19 and are connected to the hand-holding devices 4 through two sets of guide grooves 20 opened on the surface of the partition 19. The cleaning tank 1 is equipped with a three-way connecting valve 8. One end of the three-way connecting valve 8 is connected to a hot air blower, and a stop valve is installed inside the three-way connecting valve 8. The other end of the three-way connecting valve 8 is connected to two sets of first nozzles 12. The branch end of the three-way connecting valve 8 is connected to a storage tank 16. One side of the storage tank 16 is connected to a conveying pipe 17, and the other end of the conveying pipe 17 is connected to two sets of second nozzles 14. The outside of the conveying pipe 17 is connected to two sets of clamping devices 4, and the inside of the two sets of clamping devices 4 is hollow, with multiple sets of through holes 28 on the outside of the two sets of clamping devices 4.
[0020] In an optional embodiment, one end of the three-way connecting valve 8 is fixedly connected to an air supply pipe 9, and the other end of the air supply pipe 9 extends through the cleaning tank 1 to the outside of the cleaning tank 1 and is connected to the hot air. The other end of the three-way connecting valve 8 is fixedly connected to a connecting pipe A10. When using the device, medical staff insert their hands into the cleaning tank 1 through two sets of rubber rings 3. After the user inserts their hands into the cleaning tank 1, they contact their fingers with two sets of hand-holding devices 4. The hand-holding devices 4 are made of elastic material. After the user contacts their fingers with the two sets of hand-holding devices 4, the two sets of hand-holding devices 4 will fix the user's fingers. Before using the device, medical staff turn on the hot air blower in advance. After the hot air blower is turned on, it will deliver hot air through the air supply pipe 9 to the inside of the three-way connecting valve 8. After the hot air enters the inside of the three-way connecting valve 8, the initial state of the stopcock valve inside the three-way connecting valve 8 connects the three-way connecting valve 8 with the connecting pipe A10, and then the hot air that entered the three-way connecting valve 8 will enter the inside of the connecting pipe A10.
[0021] In an optional embodiment, a first bracket 11 is installed at the upper end of the cleaning tank 1. Two sets of first nozzles 12 are installed inside the first bracket 11. The other end of the connecting pipe A10 extends through the cleaning tank 1 and into the cleaning tank 1, connecting with the two sets of first nozzles 12. As described above, after hot air enters the connecting pipe A10, the hot air will be sprayed downward through the two sets of first nozzles 12. Thus, when the user's palms are not inserted into the cleaning tank 1, the hot air will preheat the inside of the cleaning tank 1. When the user inserts both hands into the cleaning tank 1, the hot air sprayed downward through the two sets of first nozzles 12, combined with the preheating inside the cleaning tank 1, will preheat the user's palms, thereby causing the pores of the user's palms to open.
[0022] In an optional embodiment, two sets of springs 6 are fixedly connected to one end of the limiting plate 5, and the other ends of the two sets of springs 6 are fixedly connected to the inner wall of the cleaning tank 1. The limiting plate 5 is slidably connected to the inner wall of the cleaning tank 1. A rack 7 is fixedly connected to one side of the limiting plate 5. As the user inserts both hands, one end of the user's fingers will contact the limiting plate 5. As the user's hands continue to be inserted, the user's fingers will push the limiting plate 5 to slide to one side. When the limiting plate 5 slides, it will drive the rack 7 to move synchronously. When the 5 moves to the point where it can no longer move, it means that the palm has moved to the appropriate position, so that medical staff can accurately position their palms without the need for other means when using the equipment.
[0023] In an optional embodiment, a valve stem 26 is fixedly connected to one end of the plug valve, and the other end of the valve stem 26 extends outward through the three-way connecting valve 8. A gear 25 is fixedly connected to the other end of the valve stem 26, and the gear 25 meshes with the rack 7. As described above, when the rack 7 slides, it will synchronously drive the gear 25 to rotate. When the gear 25 rotates, it will synchronously drive the valve stem 26 to rotate. When the valve stem 26 rotates, it will drive the plug valve inside the three-way connecting valve 8 to rotate. When the plug valve rotates, the three-way connecting valve 8 will change from being connected to the connecting pipe A10 in the initial state to being connected to the connecting pipe B15.
[0024] In an optional embodiment, a connecting pipe B15 is fixedly connected to one branch of the three-way connecting valve 8, and the other end of the connecting pipe B15 is connected to the storage tank 16. A second support 13 is connected to one side of the first support 11, and two sets of second nozzles 14 are installed inside the second support 13. As described above, after the stopcock valve inside the three-way connecting valve 8 is rotated, the hot air entering the three-way connecting valve 8 will enter the connecting pipe B15. After the hot air enters the connecting pipe B15, the connecting pipe B15 will transport the hot air to the storage tank 16, which stores disinfectant. After the gas enters the storage tank 16, it will squeeze the disinfectant in the storage tank 16 into the delivery pipe 17. The disinfectant entering the delivery pipe 17 will be atomized through the two sets of second nozzles 14 and directed towards the storage tank 16. The disinfectant is sprayed downwards, covering the back of the user's hands. During use, the user can turn their palm over so the disinfectant is sprayed onto the palm itself. This, combined with the preheating effect of the hot air, allows the disinfectant to penetrate deeper into the hands. The hot air opens the pores of the palms, allowing the atomized disinfectant to penetrate into the superficial layers of the skin, preventing blind spots in disinfection and killing pathogens hidden on the surface and in the superficial layers, reducing the risk of bacterial residue. Simultaneously, the atomized disinfectant evenly covers all parts of the hands, and in conjunction with the open pores, the disinfectant not only remains on the skin surface but also penetrates deeper, promoting the killing of bacteria or viruses on the skin surface and within the pores, resulting in better disinfection effects.
[0025] In an optional embodiment, a rotating shaft 23 rotates between the two sets of electric push rods 21. One end of the rotating shaft 23 extends through the cleaning tank 1 to the outside and is connected to a motor 24. The rotating shaft 23 is threaded. Both sets of hand-holding devices 4 are equipped with a sensing effect. After sensing that the user's fingers are in contact with the hand-holding device 4, the two sets of electric push rods 21 and the motor 24 will start synchronously. After the two sets of electric push rods 21 are started, they will push the two sets of hand-holding devices 4 to rise and fall repeatedly, thereby generating a scrubbing effect to clean between the user's fingers.
[0026] In an optional embodiment, a connecting plate 22 is threadedly connected to the threaded part of the rotating shaft 23. The two ends of the connecting plate 22 are connected to two sets of electric push rods 21. After the motor 24 starts, it drives the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it drives the connecting plate 22 to move through the threaded part of the rotating shaft 23. When the motor 24 drives the rotating shaft 23 to reverse, it drives the connecting plate 22 to move in the opposite direction, thereby causing the connecting plate 22 to move back and forth. When the connecting plate 22 moves back and forth, it drives the two sets of electric push rods 21 to move back and forth synchronously, thereby driving the two sets of hand clamping devices 4 to move synchronously, so as to thoroughly scrub the finger gaps of the user.
[0027] In an optional embodiment, a branch pipe 18 is fixedly connected to the outside of the delivery pipe 17. Two sets of flexible hoses 27 are connected to the other end of the branch pipe 18, and the other ends of the two sets of flexible hoses 27 are respectively connected to two sets of hand-holding devices 4. When the disinfectant enters the delivery pipe 17, some disinfectant is delivered to the two sets of flexible hoses 27 through the branch pipe 18. As the disinfectant enters the two sets of flexible hoses 27, the two sets of flexible hoses 27 deliver the disinfectant to the two sets of hand-holding devices 4. After entering the two sets of hand-holding devices 4, the disinfectant seeps out through multiple through holes 28 on the outside of the two sets of hand-holding devices 4, thus preventing the rapid up-and-down movement of the two sets of hand-holding devices 4 during the process of washing the user's fingers. This causes the two sets of hand-clamping devices 4 to carry away the disinfectant from between the user's fingers, resulting in incomplete cleaning. In addition, the preheating mentioned above opens the pores, which further enhances the disinfection effect between the fingers. Disinfectant continuously seeps out through the multiple sets of through holes 28 on the outside of the hand-clamping devices 4, prompting precise replenishment of disinfectant during the scrubbing process. This ensures that there is always sufficient disinfectant covering the finger gaps during the scrubbing process, preventing incomplete disinfection caused by the reciprocating movement of the two sets of hand-clamping devices 4. At the same time, the disinfectant can penetrate into the superficial layer of the skin through the open pores between the fingers, not only killing pathogenic microorganisms on the surface of the finger gaps, but also removing deep bacteria and viruses hidden in the pores of the finger gaps, greatly improving the thoroughness of disinfection. After disinfection, the user gradually withdraws their hand. When the user's fingers no longer exert force on the limiting plate 5, the limiting plate 5 resets due to the elasticity of the two sets of springs 6. During this reset, the rack 7 drives the gear 25 to rotate, causing the stopcock valve inside the three-way connecting valve 8 to rotate and reset. After the stopcock valve resets, hot air is sprayed downwards through the two sets of first nozzles 12. As the hot air sprays downwards, the user can use it to dry the disinfectant solution. The hot air preheats the user's hands before disinfection and dries them after disinfection. This automatic drying prevents the cold or sticky feeling caused by damp hands after disinfection. Warm drying also reduces skin irritation, protecting the skin barrier of medical personnel's hands. It also prevents residual wet disinfectant from affecting subsequent operations such as wearing gloves or holding instruments. Furthermore, the hot air quickly dries the hands, preventing residual liquid from creating a damp environment that breeds bacteria and poses a risk of secondary contamination.
[0028] Working principle: When using the device, medical staff insert their hands into the cleaning tank 1 through two sets of rubber rings 3. After the user inserts their hands into the cleaning tank 1, their fingers come into contact with two sets of hand-holding devices 4. The hand-holding devices 4 are made of elastic material. After the user puts their fingers into contact with the two sets of hand-holding devices 4, the two sets of hand-holding devices 4 will fix the user's fingers. Before using the device, medical staff turn on the hot air blower in advance. After the hot air blower is turned on, it will deliver hot air through the air supply pipe 9 to the inside of the three-way connecting valve 8. After the hot air enters the inside of the three-way connecting valve 8, the initial state of the stop valve inside the three-way connecting valve 8 connects the three-way connecting valve 8 with the connecting pipe A10, and then the hot air that has entered the three-way connecting valve 8 will enter the inside of the connecting pipe A10. After the hot air enters the connecting pipe A10, it will be sprayed downward through the two sets of first nozzles 12. Thus, when the user's hands are not inserted into the cleaning tank 1, the hot air will preheat the inside of the cleaning tank 1. When the user puts both hands into the cleaning tank 1, the hot air sprayed downward through the two sets of first nozzles 12, combined with the preheating inside the cleaning tank 1, will preheat the user's hands, thereby causing the pores of the user's hands to open. As the user inserts both hands, one end of the user's fingers will contact the limiting plate 5. As the user's hands continue to be inserted, the user's fingers will push the limiting plate 5 to slide to one side. When the limiting plate 5 slides, it will drive the rack 7 to move synchronously. When the rack 7 slides, it will drive the gear 25 to rotate synchronously. When the gear 25 rotates, it will drive the valve stem 26 to rotate synchronously. When the valve stem 26 rotates, it will drive the plug valve inside the three-way connecting valve 8 to rotate. When the plug valve rotates, the three-way connecting valve 8 will change from being connected to the connecting pipe A10 in the initial state to being connected to the connecting pipe B15. After the stopcock inside the three-way connecting valve 8 is rotated, the hot air entering the three-way connecting valve 8 will enter the connecting pipe B15. After the hot air enters the connecting pipe B15, the connecting pipe B15 will transport the hot air to the storage tank 16, which contains disinfectant. After the gas enters the storage tank 16, it will squeeze the disinfectant in the storage tank 16 into the delivery pipe 17. The disinfectant entering the delivery pipe 17 will be sprayed downward in an atomized state through two sets of second nozzles 14, thereby spraying the disinfectant onto the surface of the user's hands. When using it, the user can turn their palm over so that the disinfectant is sprayed onto the palm of the user's hand. At this time, combined with the preheating of the user's palm by the hot air, the disinfectant will act more deeply on the user's palm. Both sets of hand-holding devices 4 are equipped with sensing effects. After sensing that the user's fingers are in contact with the hand-holding device 4, the two sets of electric push rods 21 and motor 24 will start synchronously. After the two sets of electric push rods 21 start, they will push the two sets of hand-holding devices 4 to rise and fall repeatedly, thereby generating a scrubbing effect to clean the user's finger gaps. After the motor 24 starts, it will drive the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it will drive the connecting plate 22 to move through the thread of the rotating shaft 23. When the motor 24 drives the rotating shaft 23 to reverse, it will drive the connecting plate 22 to move in the opposite direction, thereby causing the connecting plate 22 to move back and forth. When the connecting plate 22 moves back and forth, it will synchronously drive the two sets of electric push rods 21 to move back and forth, thereby driving the two sets of hand-holding devices 4 to move synchronously, thoroughly scrubbing the user's finger gaps. When the disinfectant enters the delivery pipe 17, some of the disinfectant will be delivered to the two sets of hoses 27 through the branch pipe 18. When the disinfectant enters the two sets of hoses 27, the two sets of hoses 27 will deliver the disinfectant to the two sets of hand clamping devices 4 respectively. After the disinfectant enters the two sets of hand clamping devices 4, the disinfectant will seep out through the multiple through holes 28 on the outside of the two sets of hand clamping devices 4. This prevents the two sets of hand clamping devices 4 from carrying away the disinfectant from the user's finger gaps due to the fast up and down movement of the two sets of hand clamping devices 4 during the process of scrubbing the user's finger gaps, resulting in incomplete cleaning. In addition, the preheating mentioned above opens the pores, which will further improve the disinfection effect between the fingers. After disinfection, the user gradually withdraws their hand. At this time, after the user's fingers no longer exert any pushing force on the limiting plate 5, the limiting plate 5 will reset due to the elastic force of the two sets of springs 6. When the limiting plate 5 resets, it will drive the gear 25 to rotate through the rack 7, causing the stop valve inside the three-way connecting valve 8 to rotate and reset. After the stop valve resets, hot air will spray downward through the two sets of first nozzles 12. When the hot air sprays downward, the user can use the hot air to dry the disinfectant. Thus, the hot air will preheat the user's hands before disinfection and dry the user's hands after disinfection.
