Description

Technical Field

[0001] This invention relates to the field of disinfection device technology, specifically to a device for preventing bacterial infection in intensive care units. Background Technology

[0002] Medical staff frequently move in and out of the intensive care unit (ICU), which can easily introduce germs into the ward, increasing the risk of infection for patients. Therefore, ICUs are typically equipped with anti-bacterial devices to reduce the probability of infection and facilitate timely treatment of patients.

[0003] Currently, some anti-bacterial infection devices have been applied in intensive care units (ICUs). For example, Chinese Patent Publication No. CN114294754B discloses an anti-bacterial infection device for ICUs. This device purifies the air using a purifier, accelerates air circulation in the ward, reduces the time germs remain in the ward, and simultaneously sprays disinfectant through a misting tube to form a fog curtain when personnel enter or exit, blocking the flow of air containing bacteria from the outside. However, this existing anti-bacterial infection device still has some shortcomings.

[0004] First, although the existing technology devices are equipped with air purifiers, they do not take into account the potential slippery conditions caused by excessive disinfectant residue on the ground during the disinfection process, posing a certain safety hazard. Second, the existing technology devices do not have the function of high-temperature disinfection and rely solely on atomized disinfectant for disinfection, resulting in limited disinfection effectiveness and an inability to effectively kill some drug-resistant bacteria.

[0005] In summary, existing anti-bacterial infection devices have certain shortcomings in terms of the comprehensiveness of disinfection, the thoroughness of disinfection effect, and the safety of use, and cannot fully meet the high requirements of intensive care units for anti-bacterial infection. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a device for preventing bacterial infection in intensive care units, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for preventing bacterial infection in an intensive care unit, comprising: Main body of the device; A fan, installed inside the main body of the device, is used to blow outside air into the main body of the device; A flow guiding component, located inside the main body of the device, is used to guide the airflow inside the main body of the device; A heating element, installed at one end of the airflow guide assembly, is used to heat the air inside the airflow guide assembly; The bottom compartment, located below the main body of the device, is filled with disinfectant. A pressure assembly, installed on top of the bottom chamber, is used for the discharge of disinfectant from inside the bottom chamber; The atomizing nozzle is located inside the main body of the device and is connected to the interior of the bottom compartment.

[0008] Preferably, the airflow guiding assembly includes a first airflow guiding plate located outside the fan. The first airflow guiding plate is arc-shaped, and a heat exchange plate is provided on one side of the first airflow guiding plate. The heat exchange plate is connected to the interior of the device body by bolts, and baffles are provided at both ends of the heat exchange plate, which are connected to the heat exchange plate by bolts. The design of this airflow guiding assembly guides the airflow through the arc-shaped first airflow guiding plate, allowing the air to smoothly enter the interior of the device body and flow to the heat exchange plate. The heat exchange plate is connected to the interior of the device body, which can effectively absorb heat from the air and exchange heat.

[0009] Preferably, the heat exchange plate is internally connected to the first channel. A second guide plate is provided at one end of the top of the first channel, and the second guide plate is connected to the first guide plate by bolts. A second channel is provided at one end of the main body of the device, and the second channel is connected to the air outlet plate, which is installed at the bottom of the main body of the device. By connecting the heat exchange plate internally to the first channel and providing the second guide plate, the heated air can enter the groove at the top of the heat exchange plate under the guidance of the second guide plate, achieving further heat transfer and utilization. At the same time, the air enters the second channel after being cooled by heat exchange and is discharged downward through the air outlet plate, forming an air curtain. This process not only improves the heat utilization efficiency and reduces energy waste, but also ensures the stability and uniformity of the air curtain, allowing the air curtain mixed with disinfectant to more effectively disinfect personnel passing by, block external bacteria, and avoid the slippery problem caused by excessive disinfectant residue on the ground, thus enhancing the anti-bacterial infection effect and safety of the device.

[0010] Preferably, the heat exchange plate is multi-folded, the top surface of the heat exchange plate is in close contact with the bottom surface of the second guide plate, the two ends of the second guide plate are inclined, the heat exchange plate is made of copper-aluminum composite material, and the surface of the baffle has grooves distributed at equal intervals, the grooves on the surface of the baffle are aligned with one end of the heat exchange plate. By setting the heat exchange plate as a multi-folded copper-aluminum composite material structure, ensuring that its top surface is in close contact with the second guide plate, and that the two ends of the second guide plate are inclined, this structural design greatly increases the contact area and contact time between the air and the heat exchange plate, enabling more efficient heat exchange, allowing the air to heat up quickly and be fully heated when passing through the heat exchange plate. Meanwhile, the equally spaced grooves on the baffle surface are aligned with one end of the heat exchange plate, further optimizing the airflow path and ensuring that the air can be heated evenly through the heat exchange plate, avoiding local overheating or underheating, improving the heating efficiency and uniformity of the entire device, and thus better achieving the high-temperature sterilization effect on the air; the electrical components mentioned in this article are all connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0011] Preferably, the heating assembly includes multiple sets of electric heating tubes, with inclined plates between each set to guide airflow in a meandering pattern. The electric heating tubes are multi-bent, and fins are mounted on their exterior. Multiple fins are distributed in a straight, evenly spaced pattern, and the fins are connected to the main body of the device via a support. The design of the heating assembly, with its multiple sets of multi-bent electric heating tubes and equally spaced fins, combined with the inclined plates guiding airflow in a meandering pattern, greatly increases the contact area and contact time between the air and the electric heating tubes. This allows the air to be fully heated and rapidly heated within the heating assembly, achieving efficient high-temperature sterilization of the air. Simultaneously, the fins improve heat transfer efficiency, while the support ensures the stability and reliability of the entire heating assembly, further ensuring the uniformity and stability of the heating process. An air purifier can be added to the fan inlet to further enhance air purification.

[0012] Preferably, the pressure assembly includes a first spring installed inside the base chamber. A lifting groove is placed on top of the first spring, and a first one-way valve is installed on the surface of the lifting groove. A connecting rod is embedded in the top of the lifting groove, with one end of the connecting rod fixedly connected to a pedal. One side of the base chamber is connected to a lifting pipe, and the other end of the lifting pipe is connected to an atomizing nozzle. A one-way valve is installed inside the bottom end of the lifting pipe. This pressure assembly design, by installing a first spring inside the base chamber and placing a lifting groove on top of it, and utilizing the first one-way valve on the surface of the lifting groove and the connecting rod at the top connected to the pedal, allows pressure to be applied to the pedal when a person passes by. This causes the lifting groove to press down on the first spring, squeezing the disinfectant in the base chamber and discharging it through the lifting pipe and the one-way valve from the atomizing nozzle. This structure not only enables automatic discharge of disinfectant, saving disinfectant, but also allows control of the amount of disinfectant discharged through the pressure of the pedal, ensuring the rational use of disinfectant. Simultaneously, the one-way valve at the bottom of the lifting pipe prevents disinfectant backflow, ensuring stable operation of the device.

[0013] Preferably, the surface of the pedal is evenly distributed with grooves, and movable plates are provided on both sides of the pedal. The movable plates are rotatably connected to the pedal via hinges. The surface of the lifting groove is provided with grooves for collecting disinfectant. The side of the lifting groove is in close contact with the inner wall of the bottom compartment, and the side of the lifting groove is in sliding contact with the inner wall of the bottom compartment. By evenly distributing grooves on the surface of the pedal, the disinfectant can be evenly distributed on the surface of the pedal, effectively disinfecting the soles of pedestrians' shoes. The movable plates on both sides of the pedal are rotatably connected to the pedal via hinges, increasing the flexibility and stability of the pedal. In addition, the grooves on the surface of the lifting groove can collect disinfectant, avoiding the risk of slippery ground.

[0014] Preferably, a telescopic tube is fixedly installed inside the lifting trough. Multiple telescopic tubes are distributed in a straight line at equal intervals. One top end of each telescopic tube serves as a nozzle. A second spring is fitted around the outside of each telescopic tube. Liquid inlet holes are distributed in a ring-shaped pattern on the bottom outer wall of each telescopic tube. By fixing multiple telescopic tubes inside the lifting trough, with nozzles at the top and liquid inlet holes on the bottom outer wall, and fitted with a second spring, this structure allows the lifting trough to depress when a pedestrian steps on the pedal. The telescopic tubes draw disinfectant from the bottom chamber and spray it out through the nozzles, disinfecting the soles of the pedestrian's feet. The second spring ensures that the telescopic tubes quickly return to their original position after pressure is released, ensuring the continuity and stability of the device. This design not only improves the comprehensiveness of disinfection but also ensures that the soles of the pedestrian's feet are effectively disinfected.

[0015] This invention provides a device for preventing bacterial infection in intensive care units. It has the following beneficial effects: This intensive care unit (ICU) anti-bacterial infection device is installed above the ICU entrance and its base embedded in the ground. A fan draws outside air into the device. The air, propelled by the fan, passes beneath a heat exchange plate and, upon exiting from the other end, comes into contact with electric heating elements and fins. This vertical circulation between the heating elements allows for rapid heating and high-temperature sterilization. The heated air exits through a first channel and, aided by a second guide plate, enters a groove at the top of the heat exchange plate. The heat exchange plate preheats the initial unheated air entering the device, ensuring rapid heating when heated by the heating elements. The air at the top of the second guide plate, cooled by heat exchange, enters the second channel and exits downwards through an exhaust plate, forming an air curtain. Disinfectant sprayed from the atomizing nozzles is also expelled from the device via the airflow in the second channel, creating a disinfectant-laden air curtain that disinfects personnel passing through. Simultaneously, the air curtain helps to block external bacteria, thus preventing infection. In addition, the pressure components installed on the ground can collect residual disinfectant, and the residual heat from the air curtain can help dry the ground, effectively preventing the ground from becoming slippery due to excessive disinfectant residue and eliminating safety hazards.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] Please see Figure 1-9 This invention provides a technical solution: a bacterial infection prevention device for intensive care units, comprising: a device body 1; a fan 2 installed inside the device body 1 for blowing external air into the device body 1; a flow guiding component 3 located inside the device body 1 for guiding air circulation inside the device body 1; a heating component 4 installed at one end of the flow guiding component 3 for heating the air inside the flow guiding component 3; a bottom chamber 5 located below the device body 1 and filled with disinfectant; a pressure component 6 installed at the top of the bottom chamber 5 for discharging the disinfectant from the bottom chamber 5; and an atomizing nozzle 7 located inside the device body 1 and communicating with the bottom chamber 5. This embodiment of the intensive care unit anti-bacterial infection device uses a fan 2 to blow outside air into the main body 1 of the device. The airflow is guided by a guide component 3, and then heated by a heating component 4 to achieve high-temperature sterilization. This effectively solves the problems of limited disinfection effect and inability to kill drug-resistant bacteria in existing technologies. Simultaneously, the bottom chamber 5 of the device is filled with disinfectant. Combined with a pressure component 6 and atomizing nozzles 7, the disinfectant is automatically discharged when personnel pass through, forming an air curtain mixed with disinfectant to disinfect those passing by and block external bacteria. This solves the problems of incomplete disinfection and safety hazards in existing technologies. Furthermore, the residual heat from the air curtain helps dry any remaining disinfectant on the floor, preventing slippery surfaces and improving safety during use. Example 2

[0020] Please see Figure 1-9This invention provides a technical solution: the flow guiding assembly 3 includes a first flow guiding plate 301, located outside the fan 2, and is arc-shaped. A heat exchange plate 302 is provided on one side of the first flow guiding plate 301, which is connected to the interior of the device body 1 by bolts. Baffles 303 are provided at both ends of the heat exchange plate 302, and are connected to the heat exchange plate 302 by bolts. The interior of the heat exchange plate 302 is connected to the interior of a first channel 304. A second flow guiding plate 305 is provided at one end of the top of the first channel 304, and is connected to the first flow guiding plate 301 by bolts. A second channel 306 is provided at one end of the device body 1, which is connected to an air outlet plate 307. The air outlet plate 307 is installed on... The bottom of the main body 1 of the device; the heat exchange plate 302 is multi-bent, the top surface of the heat exchange plate 302 is closely attached to the bottom surface of the second guide plate 305, the two ends of the second guide plate 305 are inclined, the heat exchange plate 302 is made of copper-aluminum composite material, the surface of the baffle 303 has grooves distributed at equal intervals, and the grooves on the surface of the baffle 303 are aligned with one end of the heat exchange plate 302; the heating component 4 includes electric heating tubes 403, multiple sets of electric heating tubes 403 are provided, and an inclined plate is provided between each set of electric heating tubes 403 to guide the air to flow up and down in a meandering manner, the electric heating tubes 403 are multi-bent, and fins 402 are installed on the outside of the electric heating tubes 403, multiple fins 402 are distributed in a straight line at equal intervals, and the fins 402 are connected to the inside of the main body 1 of the device through the bracket 401; In this embodiment, the device is installed above the entrance / exit of the intensive care unit, and the base chamber 5 is embedded in the ground. External air is blown into the device body 1 by a fan 2. The air passes under the heat exchange plate 302 and exits from the other end of the heat exchange plate 302, contacting the electric heating tubes 403 and fins 402. The air circulates up and down among the multiple electric heating tubes 403, allowing for rapid heating and achieving high-temperature sterilization. The heated air exits through the first channel 304 and, under the action of the second guide plate 305, enters the top groove of the heat exchange plate 302. Heating the heat exchange plate 302 preheats the unheated air that has just entered the device body 1 from the bottom, thus preheating the air. When the air is heated by the electric heating tube 403, it can quickly rise in temperature. After the air at the top of the second guide plate 305 is cooled by heat exchange, it enters the interior of the second channel 306 and is then discharged downward through the air outlet plate 307, so that an air curtain can be formed below the main body 1 of the device. The disinfectant sprayed by the atomizing nozzle 7 can be discharged into the main body 1 of the device through the airflow inside the second channel 306. The air curtain mixed with disinfectant can disinfect the people passing by. At the same time, the presence of the air curtain can block external bacteria to a certain extent, so that the device can play a certain role in preventing bacterial infection. Meanwhile, the pressure component 6 set on the ground can collect the residual disinfectant on the ground, and the residual heat of the air curtain can help dry the ground, which can effectively avoid excessive disinfectant residue on the ground causing slippery conditions and safety hazards. Example 3

[0021] Please see Figure 1-9 This invention provides a technical solution: the pressure assembly 6 includes a first spring 601, which is installed inside the base chamber 5. A lifting groove 602 is placed on top of the first spring 601, and a first one-way valve 603 is installed on the surface of the lifting groove 602. A connecting rod 605 is embedded in the top of the lifting groove 602, and one end of the top of the connecting rod 605 is fixedly connected to a pedal 606. One side of the base chamber 5 is connected to a lifting pipe 604, and the other end of the lifting pipe 604 is connected to an atomizing nozzle 7. A one-way valve is provided inside the bottom end of the lifting pipe 604. The surface of the pedal 606 has evenly distributed perforations and grooves. Movable plates 607 are provided on both sides of the pedal 606. The movable plates 607 are rotatably connected to the pedal 606 via hinges. The surface of the lifting trough 602 is provided with grooves for collecting disinfectant. The side of the lifting trough 602 is tightly fitted with the inner wall of the bottom chamber 5, and the side of the lifting trough 602 is in sliding contact with the inner wall of the bottom chamber 5. A telescopic tube 609 is fixedly installed inside the lifting trough 602. Multiple telescopic tubes 609 are distributed in a straight line at equal intervals. One end of the telescopic end is a nozzle. A second spring 610 is fitted on the outside of the telescopic tube 609. Liquid inlet holes 608 are distributed in a ring at equal intervals on the bottom outer wall of the telescopic end. In this embodiment, the base chamber 5 is filled with disinfectant. When someone passes by, pressure is applied to the surface of the pedal 606, causing the pedal 606 to press down the lifting groove 602. The lifting groove 602 then presses down the first spring 601 inside the base chamber 5, which in turn squeezes the interior of the base chamber 5. Under pressure, the disinfectant inside the base chamber 5 is discharged into the lifting pipe 604, and then the disinfectant inside the lifting pipe 604 is discharged from the atomizing nozzle 7. This allows the disinfectant to be automatically discharged when a pedestrian passes by, which helps to save disinfectant. Moreover, by storing the disinfectant in the base chamber 5, it is easier to add and replenish the liquid than to store it inside the main body 1, improving the convenience of use. In addition, as a pedestrian passes by, the disinfectant inside the base chamber 5 can be discharged upward through the top end of the telescopic pipe 609, thereby disinfecting the soles of the pedestrian's feet and improving the comprehensiveness of disinfection.

[0022] Working principle: Device installation and startup The main body 1 of the device is installed above the entrance and exit of the intensive care unit, and the base 5 is embedded in the ground to ensure that the device fits tightly to the ground.

[0023] Start the fan 2, and the fan 2 will blow outside air into the main body 1 of the device.

[0024] Air heating and sterilization The blown-in air first passes under the heat exchange plate 302 and initially absorbs the heat from the heat exchange plate 302.

[0025] As the air continues to flow, it comes into contact with the electric heating tubes 403 and fins 402 when it is discharged from the other end of the heat exchange plate 302. The air circulates up and down among the multiple electric heating tubes 403, rapidly raising the temperature and achieving a high-temperature sterilization effect.

[0026] The heated air is discharged through the first channel 304 and enters below the second guide plate 305.

[0027] Preheating and heat exchange The heated air enters the top groove of the heat exchange plate 302 under the action of the second guide plate 305, and heats the heat exchange plate 302.

[0028] The heat exchange plate 302 transfers heat to the unheated air that has just entered the main body 1 of the device at the bottom, achieving a preheating effect, so that the preheated air can be heated quickly when heated by the electric heating tube 403.

[0029] Air curtain formation and disinfectant atomization The air at the top of the second guide plate 305 is cooled by heat exchange and then enters the second channel 306, and is discharged downward through the air outlet plate 307 to form an air curtain.

[0030] The disinfectant sprayed from the atomizing nozzle 7 is discharged from the main body 1 of the device along with the airflow in the second channel 306, forming an air curtain mixed with disinfectant to disinfect the personnel passing by. At the same time, the presence of the air curtain can block external bacteria to a certain extent.

[0031] Ground disinfectant collection and drying When personnel pass by, pressure is applied to the pedal 606, which presses down the lifting groove 602. The lifting groove 602 then presses down the first spring 601 in the bottom chamber 5, squeezing the disinfectant in the bottom chamber 5.

[0032] Disinfectant is discharged under pressure through riser 604 and atomizing nozzle 7 to disinfect the soles of pedestrians' feet.

[0033] The residual disinfectant on the ground is collected by the pressure component 6, and the residual heat from the air curtain helps to dry the ground, preventing it from becoming slippery and eliminating safety hazards.

[0034] Through the above process, this device achieves efficient heating and sterilization of air, automatic spraying and collection of disinfectant, and auxiliary drying of the ground, comprehensively improving the anti-bacterial infection effect at the entrance and exit of the intensive care unit and ensuring the health and safety of medical staff and patients.
