Description

Technical Field

[0001] This utility model relates to the field of biomedical technology, and in particular to an integrated irradiation device for drying and sterilizing biomedical membrane raw materials. Background Technology

[0002] In the biomedical field, biomedical membranes play an indispensable role, widely used in wound dressings, drug delivery systems, and other critical applications. The performance of biomedical membranes directly impacts medical outcomes and patient recovery, making the drying and sterilization of their raw materials crucial. Integrated irradiation equipment for drying and sterilizing biomedical membrane raw materials has emerged to address this need. This equipment combines drying and sterilization processes within a single unit, significantly improving production efficiency while reducing the risk of secondary contamination during transport, thus laying a solid foundation for ensuring the high quality and safety of biomedical membranes. With the continuous advancement of biomedicine, the performance and functional requirements of such integrated irradiation equipment are constantly increasing, necessitating technological innovation and optimization.

[0003] Existing equipment for drying and sterilizing biomedical membrane raw materials is relatively traditional in its technical principles and mechanical structure. For drying, hot air drying uses hot air blown by a hot air blower to evaporate the moisture in the raw material; the hot air circulates within the equipment, carrying away the moisture. Vacuum drying uses a vacuum pump to create a vacuum environment, lowering the boiling point of water and allowing the moisture in the raw material to vaporize rapidly at a lower temperature. In the sterilization process, ethylene oxide sterilization utilizes the strong oxidizing properties of ethylene oxide gas to penetrate the cell walls of microorganisms, destroying their protein and nucleic acid structures, thus achieving sterilization. High-temperature, high-pressure sterilization relies on the high temperature generated by high-pressure steam to coagulate and denature the proteins of microorganisms. Irradiation sterilization utilizes the high energy of radiation to destroy the DNA structure of microorganisms. In terms of equipment construction, the drying and sterilization zones are mostly separated, with raw materials moved using simple mechanical devices such as tracks and pulleys, combined with manual operation.

[0004] However, existing equipment has a significant drawback: the placement of raw materials is extremely inconvenient. When placing biomedical membrane raw materials, workers must venture deep into the equipment. The internal layout is compact, with a complex interplay of pipes, heating elements, sterilization devices, and other components, limiting operating space and making movement extremely difficult. Furthermore, the equipment's interior presents hazardous environments with high temperatures and pressures, posing safety risks to workers entering. Each placement requires extreme care, wasting considerable time and making it difficult to ensure accurate and consistent placement. This negatively impacts the uniformity of subsequent drying and sterilization, ultimately affecting product quality. Therefore, an integrated irradiation equipment for drying and sterilizing biomedical membrane raw materials is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated irradiation device for drying and sterilizing biomedical membrane raw materials, aiming to improve the problem in the prior art that the raw materials need to be inserted into the device for convenient placement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The displacement component includes a transmission belt, the outer wall of which is disposed inside the processing box. A sliding groove is provided inside the processing box, and a limiting block is provided inside the processing box. A connecting block is fixedly connected to the outer wall of the transmission belt, and the outer wall of the connecting block is slidably connected to the sliding groove. A placement plate is fixedly connected to the top of the connecting block, and a limiting block is disposed at the bottom of the placement plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the placement plate moves by activating the transmission belt.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an integrated irradiation device for drying and sterilizing biomedical membrane raw materials, comprising a processing chamber 1. The processing chamber 1 is constructed entirely of thick and sturdy stainless steel. This material not only possesses excellent corrosion resistance, effectively resisting the erosion of various chemicals and ensuring long-term stable operation of the equipment in complex environments, but also provides excellent shielding against radiation generated by the electron beam emitter 4, greatly ensuring the safety of operators and the surrounding environment. A control panel 3 is provided on the surface of the processing chamber 1. This panel employs advanced touch-sensing technology, ensuring sensitive response. Operators can easily set the drying temperature, duration, and irradiant required for sterilization with a simple touch. The system controls key parameters such as quantity and time, and features a simple and intuitive interface that greatly improves work efficiency. The outer wall of the processing chamber 1 is rotatably connected to a sealed door 5. An electron beam emitter 4 is installed on the top of the processing chamber 1, utilizing advanced electron acceleration technology to stably emit high-energy-density electron beams. These electron beams have strong penetrating power, reaching deep into the biomedical membrane raw materials to precisely destroy the DNA structure of microorganisms, thereby achieving efficient and thorough sterilization. The processing chamber 1 has a limiting groove 7 inside, and a vacuum heater 6 is fixedly connected to the side wall of the processing chamber 1. Its outer shell is made of lightweight aluminum alloy with good heat dissipation, and it is equipped with a high-efficiency vacuum pump and high-performance nickel-chromium alloy heating wire. The vacuum pump can quickly create a high vacuum inside the processing chamber 1, lowering the boiling point of water and causing the moisture in the raw materials to evaporate rapidly. The nickel-chromium alloy heating wire can precisely heat according to the set temperature, ensuring that the raw materials are heated evenly in a vacuum environment, achieving rapid and efficient drying. A displacement component is installed inside the processing chamber 1, and a sealing component is installed on the other side of the processing chamber 1.

[0034] The displacement assembly includes a transmission belt 11, which is made of high-strength, wear-resistant high-quality rubber and has multiple layers of high-strength aramid fiber reinforcement embedded inside. This allows the transmission belt 11 to maintain good mechanical properties even when subjected to huge tensile forces and long-term high-speed operation, and it will not easily break or deform. The outer wall of the transmission belt 11 is set inside the processing box 1. The processing box 1 has a sliding groove 12 and a limiting block 9 inside. The limiting block 9 is made of polyurethane material with excellent wear resistance. A connecting block 10 is fixedly connected to the outer wall of the transmission belt 11. The outer wall of the connecting block 10 is slidably connected inside the sliding groove 12. A placement plate 8 is fixedly connected to the top of the connecting block 10. A limiting block 9 is set at the bottom of the placement plate 8. The outer wall of the limiting block 9 is slidably connected inside the limiting groove 7.

[0035] Specifically, when processing biomedical membrane raw materials, the airtight door 5 is first opened, and then the transmission belt 11 is started. Once the transmission belt 11 is running, it directly drives the connecting block 10 to slide stably inside the sliding groove 12. The placement plate 8 then slowly slides out from inside the processing box 1. Simultaneously, the limiting block 9 at the bottom of the placement plate 8 slides synchronously inside the limiting groove 7. This effectively limits the placement plate 8, preventing it from shaking during sliding and ensuring the stability of its movement. After the placement plate 8 has completely slid out, its E-shaped design allows forklifts to easily pass through, enabling workers to conveniently place the raw materials on top of the placement plate 8, improving convenience. After placing the raw materials, the transmission belt 11 is started again, causing the placement plate 8 to retract back into the processing box 1. Then... With the sealed door 5 closed, the vacuum heater 6 is activated, rapidly evacuating and heating the environment inside the processing chamber 1 to dry the raw materials under vacuum. After drying, a high-energy electron beam is emitted by the electron beam emitter 4 to sterilize the raw materials. The entire process is completed seamlessly without the need to transfer the raw materials, greatly improving processing speed, ensuring product quality, and increasing production efficiency. Furthermore, it eliminates the need for frequent manual insertion of raw materials into the equipment, reducing the demand for manual labor, optimizing human resource allocation, and enabling rapid delivery of raw materials. The entire process does not require personnel to remain inside the equipment, significantly reducing radiation exposure time and further minimizing the potential harm of residual radiation to the human body.

[0036] Reference Figure 1 , Figure 3 and Figure 4The sealed assembly includes a protective housing 2, which is disposed on the outer wall of the processing box 1. An electric push rod 13 is fixedly connected to the outer wall of the processing box 1. A rack 14 is fixedly connected to the output end of the electric push rod 13. The rack 14 is made of medium carbon steel and has undergone quenching and tempering treatment, which greatly improves its hardness and wear resistance. Its tooth surface is precision milled, with accurate tooth shape, accurate meshing with the gear ring 16, and smooth transmission, effectively reducing noise and jamming during operation. A rotating disk 15 is rotatably connected to the outer wall of the processing box 1. A gear ring 16 is fixedly connected to the outer wall of the rotating disk 15, and the gear ring 16 meshes with the rack 14. The processing box 1 has a translation groove 20 and a ventilation hole 21. The rotating disc 15 has a limit groove 17 and a sealing plate 22. The sealing plate 22 is made of silicone rubber with good sealing and flexibility. Its edges are specially sealed so that it can fit tightly with the ventilation hole 21 to achieve a good sealing effect. A fixing column 18 is fixedly connected to one side of the sealing plate 22 and a limiting column 19 is fixedly connected to the other side of the sealing plate 22. The outer wall of the fixing column 18 is slidably connected to the inside of the limit groove 17, and the outer wall of the limiting column 19 is slidably connected to the inside of the translation groove 20.

[0037] Specifically, when the integrated irradiation equipment for drying and sterilizing biomedical membrane raw materials performs drying and sterilization tasks, the electric push rod 13 can be activated. After the electric push rod 13 is activated, it drives the rack 14 to move stably. Then, because the rack 14 is tightly engaged with the gear ring 16, it drives the gear ring 16 to start rotating. Due to the connection between the gear ring 16 and the rotating disk 15, the rotating disk 15 rotates synchronously, and drives the limiting groove 17 inside the rotating disk 15 to rotate. The fixed column 18 in the groove is restricted and slides, thereby pushing the connected sealing plate 22 to move. At the same time, the limiting column 19 on the other side of the sealing plate 22 slides in the translation groove 20 to ensure that the sealing plate 22 moves smoothly. Finally, the sealing plate 22 moves alternately to close the ventilation hole 21. In this way, during drying and sterilization, it can effectively isolate external dust, form a sealed space, and greatly improve drying efficiency. When the equipment is idle, the electric push rod 13 can be reversed to open the ventilation hole 21, allowing the equipment to ventilate and dissipate heat, maintain the stability of the internal environment, and prepare for the next operation.

[0038] Working principle: When processing raw materials, the airtight door 5 is opened, and then the transmission belt 11 is started. The transmission belt 11 drives the connecting block 10 to slide inside the sliding groove 12, thereby driving the placement plate 8 to slide out from inside the processing box 1. It also drives the bottom limiting block 9 to slide inside the limiting groove 7 to limit it and prevent it from shaking. Then the raw materials are placed on top of the placement plate 8. The placement plate 8 is E-shaped to allow forklifts to pass through. Then the placement plate 8 is retracted, and the airtight door 5 is closed. Then the vacuum heater 6 is started to vacuum heat and dry the raw materials. Finally, the raw materials are sterilized by the electron beam emitter 4, thus performing one-time processing without transfer, improving the processing speed.

[0039] In addition, during drying and disinfection, the electric push rod 13 can be activated, which drives the rack 14 to move. The rack 14 then drives the meshing gear ring 16 to rotate, thereby driving the rotating disk 15 to rotate. This, in turn, drives the internal limiting groove 17 to rotate, causing the internal fixed column 18 to slide and move the sealing plate 22. The limiting column 19, which is fixedly connected to the other side of the sealing plate 22, slides inside the translation groove 20 to limit it. This allows the sealing plate 22 to move alternately to close the ventilation hole 21, preventing dust from entering and forming a seal to improve drying efficiency. When not in use, it can be opened for heat dissipation and ventilation to maintain internal stability.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
