Technical Field
[0001] This utility model relates to the field of infusion bottle sterilization technology, and in particular to a dry heat low-pressure continuous sterilization device for infusion bottles. Background Technology
[0002] As widely used packaging containers in the medical industry, the sterilization of infusion bottles is crucial to ensuring drug safety and patient health. Currently, the sterilization of infusion bottles mainly relies on methods such as high-temperature autoclaving, ultraviolet irradiation, or ethylene oxide gas sterilization. Among these, dry heat sterilization has become an important method for sterilizing infusion bottles because it can effectively remove microorganisms and pyrogens without introducing moisture or chemical residues. However, in order to improve production efficiency and meet the needs of large-scale production, how to achieve continuous and automated sterilization of infusion bottles while ensuring sterilization effectiveness has become a key focus of the industry.
[0003] Existing sterilization technologies for infusion bottles typically employ high-temperature, high-pressure (HTHP) sterilization equipment. The main principle is to use steam or hot air to sterilize the infusion bottles under high pressure. This equipment usually includes a sealed sterilization chamber, a heating device, and a high-pressure control system. The infusion bottle enters the sterilization chamber via a transfer device and is maintained at a set temperature and pressure for a specific time to achieve sterilization. However, these traditional sterilization methods have limitations. For example, high temperature and pressure can cause deformation or damage to the infusion bottle material, affecting the quality of the final product. Furthermore, some sterilization methods rely on manual loading and unloading, which not only increases labor costs but also easily leads to instability in the sterilization process.
[0004] Current technologies for sterilizing infusion bottles still present certain challenges. For example, in traditional sterilization processes, misalignment or instability of the infusion bottle within the sterilization chamber can lead to uneven heating, affecting the sterilization effect. Furthermore, the numerous manual steps involved increase the risk of human error, reducing production continuity and automation. Therefore, achieving precise positioning and stable fixation of infusion bottles during sterilization to ensure uniform sterilization while simultaneously improving production efficiency remains a pressing issue for the industry.

[0028] 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.
[0029] Reference Figure 1 - Figure 6 An embodiment of this utility model provides: a dry heat low pressure continuous sterilization device for infusion bottles, including an outer shell 1, a low pressure chamber 3 fixedly connected inside the outer shell 1, a heater 4 provided on the top of the low pressure chamber 3, an electric slide rail 5 fixedly connected inside the low pressure chamber 3, a shelf 6 slidably connected to the inner wall of the electric slide rail 5, and a drive component and a limiting component provided inside the shelf 6.
[0030] The limiting assembly includes a limiting plate 11 and a limiting plate 2 1101. The outer walls of the limiting plate 11 and the limiting plate 2 1101 are slidably connected to the inside of the shelf 6. The driving assembly includes a sliding plate 1 8 and a sliding plate 2 801. The outer walls of the sliding plate 1 8 and the sliding plate 2 801 are slidably connected to the inside of the shelf 6. The outer wall of the sliding plate 1 8 is fixedly connected to one end of the limiting plate 11, and the outer wall of the sliding plate 2 801 is fixedly connected to one end of the limiting plate 2 1101. A threaded rod 7 is threadedly connected inside the shelf 6. One end of the threaded rod 7 is rotatably connected to one end of the sliding plate 1 8. A rack 1 9 is fixedly connected to the outer wall of the sliding plate 1 8, and a rack 2 901 is fixedly connected to the outer wall of the sliding plate 2 801. A gear 1 10 is rotatably connected inside the shelf 6. The rack 1 9 is meshed with the upper side of the outer wall of the gear 1 10, and the rack 2 901 is meshed with the lower side of the outer wall of the gear 1 10.
[0031] Specifically, the low-pressure chamber 3 effectively reduces the pressure of the sterilization environment, decreasing the tolerance of microorganisms and thus improving sterilization efficiency. The heater 4 provides continuous high temperature to further eliminate microorganisms inside and outside the bottle, ensuring thorough sterilization. To ensure the infusion bottle is stably placed during sterilization, it must be correctly placed inside the placement plate 6. At this time, the threaded rod 7 begins to function. By driving the threaded relationship between the threaded rod 7 and the placement plate 6, one end of the threaded rod 7 drives the sliding plate 8 to slide smoothly inside the placement plate 6. The movement of the sliding plate 8 causes the rack 9 to move as well. With the precise meshing between the rack 9 and the gear 10, the rack 9 drives the gear 10 to rotate. The rotation of the gear 10... The movement further drives the rack 2 901 below to move synchronously in the opposite direction to the rack 1 9. This mutual movement of the rack 1 9 and the rack 2 901 causes the limiting plate 1 11 and the limiting plate 2 1101 to move in the opposite direction, thereby enabling the limiting rubber pad 19 to accurately clamp and fix the infusion bottle. Then, the placement plate 6 is placed inside the electric slide rail 5, and the placement plate 6 and the infusion bottle are driven forward by the electric slide rail 5. As this series of actions are carried out, the low-pressure chamber 3 is activated to reduce the pressure and complete the creation of a low-pressure environment. Finally, the heater 4 is activated to sterilize the infusion bottle by heating at low temperature. After sterilization, the placement plate 6 is sent to the cooling chamber behind by the electric slide rail 5 to ensure the continuity of the entire sterilization process.
[0032] Reference Figure 1 , Figure 7 and Figure 8 A protective door 2 is rotatably connected to one side of the outer wall of the outer casing 1. An arc-shaped connecting plate 12 is rotatably connected to one side of the outer wall of the low-pressure chamber 3. A sealed chamber door 13 is rotatably connected to one end of the arc-shaped connecting plate 12. A control component is installed inside the arc-shaped connecting plate 12. A limit buckle 17 is provided on the other side of the outer wall of the low-pressure chamber 3. A sealing ring 18 is provided at the opening of the low-pressure chamber 3. The control component includes a rotating shaft 14, which is rotatably connected to the outer wall of the arc-shaped connecting plate 12. A gear is fixedly connected to one end of the rotating shaft 14. 15. An arc-shaped toothed plate 16 is fixedly connected to the outer wall of the sealed chamber door 13. Gear 2 15 meshes with the arc-shaped toothed plate 16. Rack 1 9 and rack 2 901 are slidably connected inside the storage plate 6. One side of the outer wall of the sealed chamber door 13 is rotatably connected to the inner wall of the low-pressure chamber 3. A sealing rubber ring is provided on the side wall of the sealed chamber door 13 facing the low-pressure chamber 3. One side of the outer wall of the limiting buckle 17 is slidably connected to the inside of the sealed chamber door 13. One side of the outer wall of the sealed chamber door 13 is attached to the outer wall of the sealing ring 18.
[0033] Specifically, the automatic rotation and opening / closing of the sealing chamber door 13 is achieved by driving the rotating shaft 14 to rotate the gear 15, and then by the meshing relationship between the arc-shaped toothed plate 16 and the gear 15. When the sealing chamber door 13 rotates to a certain angle, one side of it can disengage from the outer wall of the limiting buckle 17, thereby releasing or fixing the door, making the operation more convenient. In addition, the device is equipped with a sealing ring 18, which can tightly seal the interface between the low-pressure chamber 3 and the arc-shaped connecting plate 12 when the sealing chamber door 13 is closed, effectively preventing gas leakage during sterilization and ensuring the stability of the low-pressure environment. This not only improves the safety of the sterilization process but also avoids the decrease in sterilization effect due to poor sealing. At the same time, the automatic opening and closing design of the sealing chamber door 13 reduces the complexity of manual operation, improves the overall operability of the equipment, and makes the sterilization device more efficient, stable, and easy to maintain during use.
[0034] Working principle: When the dry heat low-pressure continuous sterilization device for infusion bottles is needed, the infusion bottle is first placed inside the placement plate 6. Then, the threaded rod 7 is driven, and the threaded relationship between the threaded rod 7 and the placement plate 6 causes one end of the threaded rod 7 to drive the sliding plate 8 to slide inside the placement plate 6, thereby driving the rack 9 to move. The meshing relationship between the rack 9 and the gear 10 causes the rack 9 to drive the gear 10 to rotate. This, in turn, causes the rack 901 below to move synchronously in the opposite direction to the rack 9. The movement of rack 1 9 and rack 2 901 drives the limit plate 1 11 and limit plate 2 1101 to move in opposite directions, thereby cooperating with the limit rubber pad 19 to clamp and fix the infusion bottle. Then, the placement plate 6 is placed inside the electric slide rail 5, and the electric slide rail 5 drives the placement plate 6 and the infusion bottle above it to move. Then, the low pressure chamber 3 inside the outer shell 1 is activated to reduce the pressure. Finally, the heater 4 is activated to perform low pressure sterilization. After sterilization, the placement plate 6 is transported to the cooling chamber behind through the electric slide rail 5 to achieve continuous sterilization.
[0035] In addition, the drive shaft 14 drives the gear 15 to rotate, and then the meshing relationship between the gear 15 and the arc-shaped toothed plate 16 causes the arc-shaped toothed plate 16 to drive the sealing door 13 to rotate with the rotation of the gear 15. When the sealing door 13 rotates to a certain extent, one side of the sealing door 13 can be rotated out of the outer wall of the limit buckle 17, thereby fixing or releasing the sealing door 13. During this process, the sealing ring 18 can be used to seal the low-pressure chamber 3 and the arc-shaped connecting plate 12 to prevent air leakage and facilitate opening and closing.
[0036] 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.
