Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a medical disinfection and cleanroom door, which is suitable for places with extremely high requirements for environmental cleanliness and disinfection, such as hospital operating rooms, ICU wards, and sterile laboratories. It aims to achieve efficient automatic disinfection, strict sealing and isolation, and convenient passage by optimizing the mechanical structure, effectively preventing cross-infection of germs and improving the safety of the medical environment. Background Technology
[0002] In medical environments, medical doors serve as isolation barriers between different functional areas, and their disinfection and cleaning performance is crucial for controlling the spread of pathogens and ensuring medical safety. Currently, traditional medical doors have several problems:
[0003] First, the disinfection methods are outdated. Most medical doors rely on manual, periodic spraying or wiping with disinfectant, which is not only inefficient but also creates blind spots in disinfection, making it difficult to ensure thorough disinfection of the door surface, especially corners and crevices. During periods of high incidence of infectious diseases, the lag in manual disinfection may lead to the rapid spread of germs, increasing the risk of infection for both medical staff and patients.
[0004] Secondly, the sealing performance is poor. Traditional medical doors have a simple sealing structure, relying solely on ordinary rubber sealing strips. After long-term use, the sealing strips are prone to aging and deformation, resulting in poor sealing. Air can easily flow between the door and the door frame, causing air pollution in the clean area and failing to meet the stringent air cleanliness requirements of operating rooms, sterile laboratories, and other similar locations.
[0005] Third, the accessibility is insufficient. In emergencies, the traditional opening method of medical doors is cumbersome and time-consuming, potentially delaying treatment. Furthermore, some medical doors lack automatic sensor functionality, making it difficult for medical staff to open them conveniently when carrying medical instruments, thus reducing work efficiency.
[0006] Therefore, we have made improvements to this and proposed a medical disinfection and cleanroom door. Utility Model Content
[0007] The purpose of this invention is to provide a medical disinfection and cleanroom door, and the device thereof.
[0008] In order to achieve the above-mentioned objectives, this utility model provides a medical disinfection and cleanroom door to solve the above problems.
[0009] This utility model specifically includes:
[0010] The door body adopts a double-layer hollow structure. The outer layer is a high-strength stainless steel plate, and the inner layer is an antibacterial engineering plastic plate. The space between the two layers is filled with heat insulation and sound insulation material. The door body edge is set with stepped sealing grooves, and multiple sealing strips are installed in the sealing grooves. The door body surface is provided with disinfection nozzle installation holes.
[0011] The disinfection system includes a storage tank, a pressurizing pump, pipelines, and disinfection nozzles. The storage tank is installed above the door frame. The pressurizing pump is connected to the storage tank and delivers disinfectant to the disinfection nozzles on the door surface through the pipelines. The disinfection nozzles are fan-shaped spray nozzles. Ultraviolet disinfection lamps are also installed inside the door.
[0012] The drive and control mechanism includes a motor, a transmission belt, a guide rail, pulleys, an infrared sensor, a controller, and an operation panel. The motor is installed in a motor box at the top of the door frame and is connected to the pulleys on the door body via the transmission belt, driving the door body to move horizontally on the guide rail. The infrared sensor is installed on both sides of the door body and above the door frame to detect people or objects approaching. The controller receives the infrared sensor signal and controls the motor to run. The operation panel is installed on one side wall of the door body for manually controlling the door's opening, closing, disinfection, and other functions.
[0013] The auxiliary structure includes an exhaust device above the door frame and anti-collision strips on both sides of the door. The exhaust device includes an exhaust fan and an air filter. The anti-collision strips are made of rubber and have anti-slip textures on the surface.
[0014] Preferably, the sealing strip includes a main sealing strip, an auxiliary sealing strip, and a dustproof strip. The main sealing strip is made of silicone rubber, and the auxiliary sealing strip is made of EPDM rubber.
[0015] Preferably, the disinfection nozzles are evenly distributed on the surface of the door, enabling 360-degree disinfection without dead angles. The spray angle and flow rate of the nozzles can be controlled by adjusting the pressure of the booster pump and the valves on the pipeline.
[0016] Preferably, the ultraviolet disinfection lamp is installed in the interlayer of the door and has a timer switch function, which can be turned on automatically after the door is closed.
[0017] Preferably, the guide rail is made of high-strength aluminum alloy and the surface is anodized, and the pulley is made of nylon and fits tightly with the guide rail.
[0018] Preferably, the anti-pinch device uses a combination of a pressure sensor and an infrared beam sensor. When the door encounters an obstacle during the closing process, the pressure sensor detects a change in pressure, and the infrared beam sensor detects that the obstacle is blocking the light. The two work together to cause the controller to reverse the motor and the door to open automatically.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. The automatic disinfection system achieves comprehensive and efficient disinfection of the door surface through 360-degree spraying without dead angles and deep irradiation by ultraviolet disinfection lamps.

[0033] Door 101 Structure
[0034] The door body 101 of this medical disinfection and cleanroom door adopts a double-layer hollow structure. The outer layer is made of high-strength stainless steel plate, which is corrosion-resistant and easy to clean, facilitating daily disinfection and wiping. The inner layer is made of antibacterial engineering plastic plate, which can inhibit the growth of bacteria. The space between the two layers is filled with high-efficiency heat and sound insulation materials, such as rock wool or polyurethane foam, which can not only improve the heat and sound insulation performance of the door body 101, but also enhance the structural strength of the door body 101.
[0035] The door 101 has a stepped sealing groove along its edge, within which multiple sealing strips 102 of different shapes are installed, including a main sealing strip 102, an auxiliary sealing strip 102, and a dustproof strip 201. The main sealing strip 102 is made of silicone rubber, which has good elasticity and high-temperature resistance. When the door is closed, the main sealing strip 102 fits tightly against the door frame, forming the first sealing barrier. The auxiliary sealing strip 102 is located inside the main sealing strip 102 and is made of EPDM rubber, further enhancing the sealing effect. The dustproof strip 201 is used to prevent dust and debris from entering the sealing groove, extending the service life of the sealing strip 102.
[0036] The surface of the door 101 is provided with several disinfection nozzle mounting holes 103 for installing disinfection nozzles 107 to achieve automatic disinfection of the surface of the door 101.
[0037] Disinfection system
[0038] The disinfection system includes a storage tank 104, a pressure pump 105, pipes 106, and disinfection nozzles 107. The storage tank 104 is installed above the door frame and is used to store disinfectant. The capacity of the storage tank 104 can be designed according to actual usage needs, generally 5-10 liters. The pressure pump 105 is connected to the storage tank 104 and delivers the disinfectant to the disinfection nozzles 107 on the surface of the door 101 via pipes 106.
[0039] The disinfection nozzle 107 uses a fan-shaped spray nozzle, which is evenly distributed on the surface of the door 101, and can achieve 360-degree disinfection without dead angles. The spray angle and flow rate of the nozzle can be controlled by adjusting the pressure of the booster pump 105 and the valve on the pipeline 106, ensuring the disinfection effect while avoiding waste of disinfectant.
[0040] An ultraviolet disinfection lamp 108 is also installed inside the door 101. The ultraviolet disinfection lamp 108 is installed in the interlayer of the door 101 and shines on the surface of the door 101 through a transparent quartz glass window. The ultraviolet disinfection lamp 108 has a timer switch function and can be turned on automatically after the door is closed to perform deep disinfection of the door 101 and effectively kill bacteria and viruses.
[0041] Drive and control mechanism
[0042] The door 101 adopts an electrically operated sliding opening mechanism. The drive mechanism includes a motor 109, a transmission belt 110, a guide rail 111, and pulleys 112. The motor 109 is installed in a motor box 119 at the top of the door frame and is connected to the pulleys 112 on the door 101 via the transmission belt 110, driving the door 101 to slide left and right on the guide rail 111. The guide rail 111 is made of high-strength aluminum alloy with an anodized surface, providing excellent wear resistance and smoothness. The pulleys 112 are made of nylon, fitting tightly with the guide rail 111, ensuring smooth operation and low noise.
[0043] The control mechanism includes an infrared sensor 113, a controller 114, and an operation panel 115. The infrared sensor 113 is installed on both sides of the door 101 and above the door frame to detect the approach of people or objects. When the infrared sensor 113 detects a person or object approaching, it transmits a signal to the controller 114, which then starts the motor 109, automatically opening the door 101. The operation panel 115 is installed on the wall on one side of the door 101. Operators can manually control the door's opening, closing, and disinfection functions via the operation panel 115, and can also set parameters such as disinfection time and disinfection mode.
[0044] To ensure safety, the door 101 is also equipped with an anti-pinch device. The anti-pinch device uses a combination of a pressure sensor 601 and an infrared beam sensor 602. When the door encounters an obstacle during closing, the pressure sensor 601 detects a change in pressure, and the infrared beam sensor 602 detects that the obstacle is blocking the light. The two work together to transmit a signal to the controller 114. The controller 114 immediately controls the motor 109 to reverse, and the door 101 automatically opens to prevent injury to people or damage to items.
[0045] Auxiliary structure
[0046] An exhaust system is installed above the door frame, comprising an exhaust fan 117 and an air filter 118. The exhaust fan 117 uses an axial flow fan, characterized by large air volume and low noise, and can promptly remove the mist and odors generated during the disinfection process. The air filter 118 uses a high-efficiency HEPA filter, which can effectively filter out fine particles and germs in the air, ensuring that the exhausted air is clean and uncontaminated.
[0047] The door 101 is also equipped with anti-collision strips 116 on both sides. The anti-collision strips 116 are made of rubber and have anti-slip texture on the surface. They can protect the door 101 and the safety of people, and reduce the impact and noise when the door is closed.
[0048] The usage process of the medical disinfection and cleanroom door provided by this utility model is as follows:
[0049] Normal passage: When medical staff or patients carrying items approach the door 101, the infrared sensors 113 on both sides and above the door 101 detect the signal and transmit it to the controller 114. The controller 114 then starts the motor 109, and the door 101 automatically slides to one side to open. After the person or item has passed, the infrared sensors 113 detect the disappearance of the signal, the controller 114 controls the motor 109 to reverse, and the door 101 automatically closes.
[0050] Disinfection Operation: When door 101 needs to be disinfected, the operator can select a disinfection mode, such as timed disinfection or manual disinfection, via the control panel 115. In timed disinfection mode, the disinfection time interval and duration of each disinfection session can be set. In manual disinfection mode, pressing the disinfection start button activates the controller 114, which in turn activates the pressure pump 105 to deliver disinfectant through pipe 106 to the disinfection nozzle 107, spraying disinfectant onto the surface of door 101. Simultaneously, the ultraviolet disinfection lamp 108 automatically turns on for deep disinfection of door 101. After disinfection, the exhaust fan 117 automatically starts to expel the generated mist and odors.
[0051] Emergency Handling: During the closing process of door 101, if an obstacle such as a person or object is encountered, the pressure sensor 601 of the anti-pinch device detects a pressure change, and the infrared beam sensor 602 detects that the light is blocked. Both transmit signals to the controller 114, which immediately controls the motor 109 to reverse, and door 101 automatically opens to prevent injury to personnel or damage to items. After the obstacle is removed, door 101 automatically closes again.
