Abstract
Description
Technical Field
[0001] This utility model relates to the field of disinfection equipment technology, specifically to a sterilization cabinet for lead aprons in radiology departments with sterilization effects. Background Technology
[0002] Lead aprons are a special type of clothing, particularly common in hospital radiology departments. Medical staff and patients can use lead aprons to shield themselves from radiation, minimizing the harm caused by radiological examinations. However, under current technology, the disinfection, cleaning, storage, and maintenance of lead aprons present the following problems:
[0003] 1) Relies on manual operation, which is inefficient and labor-intensive:
[0004] Current technologies mostly involve manually spraying disinfectant and then wiping the aprons, a process that is cumbersome and time-consuming. Lead aprons can weigh up to 15 kilograms, and female medical staff experience significant physical exertion during operation, which can easily lead to fatigue and improper operation. In addition, traditional methods require wiping each apron individually, and the aprons are exposed and stored after disinfection, making them susceptible to secondary contamination and further increasing the workload of repeated disinfection.
[0005] 2) The disinfection methods are limited and cannot cope with complex contamination scenarios:
[0006] Most devices only support a single disinfection mode (such as spray only or ultraviolet only) and cannot adjust the disinfection intensity according to the degree of lead apron contamination (such as routine surgery versus infectious disease surgery). For example, a regular spray mode may not be sufficient to kill stubborn pathogens such as hepatitis B virus, while the use of ultraviolet light has disinfection limitations and may cause harm to the human body when handling the device.
[0007] 3) Risk of secondary pollution caused by material and process defects
[0008] Inferior disinfection cabinets may use non-food grade silicone or cheap steel, which may release harmful substances (such as formaldehyde and volatile organic compounds) during high-temperature or chemical disinfection processes, contaminating the surface of lead aprons.
[0009] Inferior disinfection cabinets, due to unreasonable design, may have blind spots that are not thoroughly disinfected, thus affecting the sterilization effect.
[0010] 4) Inadequate storage and maintenance management
[0011] If the storage environment for disinfected lead aprons is not completely sealed, it is susceptible to contamination by environmental microorganisms, leading to the need for repeated disinfection. In addition, improper equipment maintenance (such as failure to replace filters regularly) may breed bacteria and reduce disinfection efficiency.
[0012] Therefore, this application is submitted to resolve the aforementioned issues. Summary of the Invention
[0013] The purpose of this invention is to provide a radiology lead apron sterilization cabinet with sterilization and storage effects. This cabinet integrates sterilization, storage and drying functions, fundamentally solving problems such as incomplete sterilization of lead aprons, complicated operation, secondary pollution and material damage.
[0014] To achieve the above objectives, this utility model provides the following technical solution:
[0015] A sterilization cabinet for radiology lead aprons with sterilization effect includes a sterilization cabinet body, characterized in that the sterilization cabinet body is provided with a sealed door, a fresh air inlet and a PLC controller are provided on the top of the sterilization cabinet body, and casters are provided on the bottom of the sterilization cabinet body;
[0016] The sterilizer cabinet body has a plasma electrode air outlet and a negative ion hot air drying module connected to the fresh air inlet pipe on its internal top wall. A plasma generator is installed above the plasma electrode air outlet. A return air inlet for air circulation is installed below the fresh air inlet. An ozone generator is connected to one side of the return air inlet.
[0017] The sterilization cabinet is equipped with a temperature and humidity sensor and several hanging racks inside. The hanging racks are equipped with hooks for hanging lead aprons.
[0018] The negative ion hot air drying module, plasma generator, and ozone generator are all electrically connected to the PLC controller.
[0019] Furthermore, the sealed door is characterized by having an observation window.
[0020] Furthermore, the sterilization cabinet is characterized in that its main body is a double-layer stainless steel structure, with a lead shielding layer on the inner layer and 304 stainless steel on the outer layer, and the thickness of the lead shielding layer is 0.5-1mm.
[0021] Furthermore, the plasma generator is characterized by the following parameters: voltage 10-20KV; frequency 13.56MHz; and processing air volume 1000m3 / h.
[0022] Furthermore, the sealing door is characterized by having a silicone sealing ring on its edge surface and an access control linkage protection mechanism electrically connected to the PLC controller.
[0023] Furthermore, the sterilization cabinet body is characterized by having a circuit overload protection device and a fault alarm electrically connected to the PLC controller.
[0024] The beneficial effects of this utility model are as follows:
[0025] 1. Highly efficient sterilization: The synergistic effect of ozone and plasma achieves a sterilization rate of over 99.9%, which is 50% more efficient than traditional single sterilization methods;
[0026] 2. Continuous antibacterial effect: The plasma module can maintain a sterile environment inside the cabinet for a long time, and no re-sterilization is required during the storage of the lead apron;
[0027] 3. Intelligent and convenient: Automated programs reduce manual intervention, the touch interface is easy to operate, and the historical data function facilitates quality control;
[0028] 4. Safe and reliable: The sealed structure and ozone concentration monitoring prevent leakage, protecting the health of medical staff.
[0029] 5. Space optimization: The multi-layer hanging rack design can sterilize and store multiple lead aprons at the same time, which is suitable for high-frequency use scenarios in radiology departments.

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0035] Unless otherwise specified, the technical solutions described in this utility model are all conventional solutions in the field; unless otherwise specified, the reagents or materials described are all from commercial channels.
[0036] Please see Figure 1 This utility model provides a sterilization cabinet for radiology lead aprons with sterilization effect, including a sterilization cabinet body, a pair of sealed doors 1 on the sterilization cabinet body, a fresh air inlet 3 and a PLC controller 5 on the top of the sterilization cabinet body, and multiple sets of casters 12 at the bottom of the sterilization body, the casters 12 being equipped with a braking mechanism.
[0037] Specifically, the sterilizer has a plasma electrode outlet 6 and a negative ion hot air drying module 7 connected to the fresh air inlet 3 pipe on the top wall inside the main body. Above the plasma electrode outlet 6 is a corresponding plasma generator 4. Below the fresh air inlet 3 is a return air inlet 10 for air circulation. One side of the return air inlet 10 is connected to an ozone generator 11.
[0038] Furthermore, the sterilization cabinet is also equipped with a temperature and humidity sensor 8 and multiple hanging racks, with multiple hooks 9 for hanging lead aprons.
[0039] Preferably, the sealed door 1 is provided with an observation window 2.
[0040] Specifically, the parameters of the sterilizer shown in this application are as follows:
[0041] The main body of the sterilizer is a double-layer stainless steel structure, with a lead shielding layer on the inner layer and 304 stainless steel on the outer layer. Preferably, the thickness of the lead shielding layer is 0.5-1mm.
[0042] The core sterilization system, consisting of 4 plasma generators, 11 ozone generators, and 7 negative ion hot air drying modules, is the most cost-effective component.
[0043] Plasma generator 4: Radio frequency plasma, voltage 10-20KV; frequency 13.56MHz; processing air volume 1000m3 / h;
[0044] Ozone generator 11: Concentration 10-30ppm, with air pump circulation system;
[0045] Negative ion sterilization can neutralize residual ozone, while PTC ceramic heating is used to assist in maintaining a constant temperature of 40-50℃ inside the sterilizer.
[0046] The edge surface of the sealed door 1 is equipped with a silicone sealing ring, and is intelligently controlled by the access control linkage protection mechanism, which can automatically cut off the power supply of the sterilization system when the door is opened.
[0047] Furthermore, the PLC controller 5, temperature and humidity sensor 8, and safety protection module form an intelligent control system. The PLC controller 5 presets sterilization programs, such as daily mode, deep mode, and emergency mode. At the same time, the temperature and humidity sensor 8 monitors the internal environment of the sterilization cabinet in real time and controls the sterilization system to keep the internal temperature ≤40℃ and humidity ≤30%RH.
[0048] In addition, the safety protection module includes circuit overload protection devices, fault alarms, and access control linkage protection to ensure the safe operation of the equipment.
[0049] Working principle:
[0050] After the lead apron is hung on the hook, the sealed door is closed. The intelligent control system controls the internal environment of the sterilization cabinet, sterilizes and disinfects the lead apron through an ozone generator and a plasma generator, and neutralizes residual ozone through negative ion sterilization. During this process, a safety protection module ensures stable operation of the equipment.
[0051] In summary, this invention, based on in-depth research and optimization of key parameters for plasma electrode air purification, innovatively employs dielectric barrier discharge (DBD) technology. By precisely controlling the 10kV high-frequency voltage and optimizing the electrode structure, it achieves a power density of up to 5kW / m³ per unit volume, effectively improving the yield of active particles. Simultaneously, combined with a unique gas flow design, the residence time of air in the plasma region is extended to over 0.3 seconds. Coupled with a 30%-70% humidity adaptive adjustment module, the logarithmic removal rates for common bacteria and viruses reach 6log and 5log respectively, far exceeding the industry average.
[0052] Furthermore, this invention integrates an ozone catalytic decomposition device, strictly controlling the ozone concentration generated during operation to 10-30 mg / m³, ensuring efficient sterilization while fully meeting indoor air quality safety standards. Compared to traditional air purification equipment, this invention not only achieves a dual breakthrough in sterilization efficiency and safety but also reduces maintenance costs through modular design. It possesses significant market application value and technological leadership, and is expected to provide a brand-new solution for air purification in medical, household, and other fields.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
