The core of this patent isAn Intelligent Disinfection Device Adapted for Hospital Ward Scenarios, its greatest technological innovation lies inThree-axis rotatable force arm unit integrated with a mobile chassis, enabling close-range, scanning-style disinfection of both planar and three-dimensional obstacles within hospital wards. This approach overcomes the common drawbacks of traditional ultraviolet (UV) disinfection, such as numerous blind spots, low efficiency, and high radiation risks. Furthermore, by integrating functions like obstacle recognition, prioritized disinfection, and human infrared detection, it makes hospital ward disinfection more intelligent, precise, and safe.
Nosocomial InfectionHospital-acquired infections (HAIs) represent a critical medical safety issue requiring urgent prevention and control in clinical practice. HAIs refer to infections acquired by patients during diagnosis and treatment within a healthcare facility, as well as infections contracted by healthcare workers during their occupational duties. Microorganisms such as bacteria and fungi in ward environments can spread through various routes, including air, aerosols, and direct contact, serving as the primary drivers of HAIs. These infections not only prolong hospital stays and increase treatment costs but may also exacerbate patients’ conditions and lead to severe complications, thereby significantly adversely affecting patient prognosis and the quality of medical care. Consequently, efficient and comprehensive disinfection of hospital wards is a key measure in preventing and controlling HAIs.
Current clinical UV disinfection protocols for hospital wards are predominantlyUltraviolet light with wavelengths of 200 to 280 nm is emitted using a mercury lamp., thereby achieving disinfection by destroying microbial cell structures and causing cell death. Meanwhile, some technologies have attempted to apply high-energy pulsed UV lamps in the field of sterilization and disinfection, such as mobile pulsed UV disinfection robots and airborne disinfection systems.
However, all existing disinfection protocols exhibit significant technical limitations and fail to meet the clinical demand for precision disinfection. Traditional mercury lamp disinfection suffers from inherent drawbacks such as mercury content and fragility, posing potential risks of chemical contamination. Furthermore, it is characterized by prolonged disinfection cycles and unstable ultraviolet (UV) intensity in practical applications. The sole reliance on long-distance irradiation readily creates disinfection blind spots, leading to microbial residue. Conversely, while disinfection systems equipped with high-energy pulsed UV lamps can achieve rapid and efficient area-wide disinfection, they pose substantial radiation safety risks due to the intense ionizing radiation emitted by the lamps and their high operational complexity. Consequently, these systems are unsuitable for the unique clinical scenarios of hospital wards, which feature frequent personnel movement and complex environments.
Against this backdrop, there is an urgent clinical need to upgrade ward disinfection technologies, necessitating a novel disinfection device tailored to hospital ward settings. Such a device must overcome the limitations of traditional disinfection methods—including numerous blind spots, low efficiency, and contamination risks—while avoiding the radiation hazards associated with high-energy pulsed ultraviolet light. By enabling intelligent and precise disinfection processes, it aims to comprehensively enhance the efficacy and safety of ward disinfection, reduce the incidence of healthcare-associated infections at the source, and establish a robust medical safety barrier for clinical diagnosis, treatment, and patient recovery.
This close-range scanning high-energy pulsed UV disinfection device achieves hospital ward disinfection through multi-dimensional technological innovations.Intelligent, Precise, and Efficient, demonstrating comprehensive technical advantages over traditional disinfection solutions, with core innovations and benefits reflected inStructural Design, Sterilization Method, Safety Protection, Intelligent Controland other aspects.
In terms of structural design,, the device innovatively adoptsTriaxial Rotatable Force Arm Unit AssemblyThe first, second, and third linkage arm units can rotate to predetermined angles in the vertical plane, horizontal plane, and vertical plane, respectively. Coupled with a mobile chassis structure, the device allows flexible adjustment of disinfection angles and positions, overcoming the spatial limitations of traditional disinfection equipment. It enables blind-spot-free scanning of all surfaces of both planar and three-dimensional obstacles, such as hospital beds and cabinets, within patient rooms. Meanwhile, storage compartments on both sides of the fuselage house the linkage arms and UV lamp tubes, achieving multifunctional switching and a compact design.
In terms of disinfection methods, the device innovatively adoptsShort-Range Targeted Disinfection Mode, controlling the distance between the high-energy pulsed UV lamp tube and the surface of obstacles to ≤20 cm, with the lamp tube directionally emitting high-energy pulsed ultraviolet rays, which not only significantly improves disinfection efficiency but also avoids indiscriminate scattering of ultraviolet light; meanwhile, the high-energy pulsed UV lamp tubes equipped in the device are filled with xenon and argon gases, combined with a cooling channel design, eliminating the mercury-containing structure of traditional mercury lamps, thereby eradicating the risk of chemical pollution at its source. The device also integrates three modes—fixed scanning, three-dimensional scanning, and conventional disinfection—to meet the disinfection needs of different scenarios within hospital wards.
At the Level of Intelligent Control, the device integrates multiple intelligent modules, including obstacle type recognition, priority setting, and path planning, throughConstruction of 3D Maps of Ward Environments Using Multi-Sensor Fusion and SLAM Technologies, combined with convolutional neural networks to achieve precise identification and matching of obstacles. It can assign scanning weights ranging from 0.5 to 1.0 based on patient contact frequency, prioritizing high-contact items such as hospital beds to enable disinfection in order of risk level, thereby making the disinfection process more targeted. Meanwhile, the path planning module automatically plans the movement trajectory of the device and the operational path of the robotic arm, adjusting the arm’s actions according to the three-dimensional structure of different obstacles to achieve fully automated scanning disinfection, significantly reducing manual operation costs.
In terms of safety protection, Innovative Device ConfigurationInfrared Detection Unit, enabling real-time detection of human presence, orientation, and distance to promptly avoid exposure during force arm adjustment and disinfection processes. Combined with the design of directional ultraviolet (UV) emission, this dual approach significantly reduces the radiation risks associated with high-energy pulsed UV light, thereby addressing safety challenges in the application of high-energy pulsed UV lamps in hospital wards. Furthermore, the device marks and provides feedback on disinfection points that are inaccessible, ensuring that the completion of disinfection tasks is traceable and verifiable.
Overall, the device willMechanical Structure Innovation, Intelligent Algorithm Application, and High-Energy Sterilization TechnologyDeep integration not only addresses the pain points of traditional ultraviolet disinfection—such as numerous blind spots, low efficiency, and secondary pollution—but also avoids the radiation risks associated with existing high-energy pulse sterilization technologies. This approach achieves a triple enhancement in disinfection efficacy, operational efficiency, and usage safety, providing a novel technical solution for the prevention and control of nosocomial infections in hospital wards.
