[0020] Example 1

[0021] like Figs. 1-4As shown, the dual-chamber pre-filled syringe barrel 7 loading device with independent locking positions 10 of this utility model includes a loading base 1 and a base cover 2. The loading base 1 and base cover 2 are provided with matching fixing components. The loading base 1 has a loading cavity 8, and several locking positions 10 are evenly arranged within the loading cavity 8. The base cover 2 has a notch. After the base cover 2 and the loading base 1 are assembled, a sterilization channel 3 is formed. There are eight sterilization channels 3 in total, respectively located at the top corner and the center of the edge of the base cover 2. The top corner is triangular, and the center of the edge is semi-circular. The fixing components include several snap-fit ​​protrusions 5 on the loading base 1 and snap-fit ​​protrusions on the base cover 2. The corresponding snap-fit ​​grooves 4 securely connect the loading base 1 and the base cover 2 via snap-fits. The base cover 2 provides limiting protection for the dual-chamber pre-filled syringe syringe 7 inside the loading base 1. The loading cavity 8 has staggered limiting blocks 9 on both sides, corresponding to the locking positions 10. Each locking position 10 has a limiting block 9 on one side, and the limiting blocks 9 corresponding to adjacent locking positions 10 are located on different sides. This allows the dual-chamber pre-filled syringe syringe 7 to be placed alternately from left to right during loading, fully utilizing the storage space. The limiting blocks 9 minimize movement of the dual-chamber pre-filled syringe syringe 7 on the locking positions 10. The top of the base cover 2 has a gripping and positioning block 11 for gripping and positioning. Block 11 consists of four blocks, symmetrically placed on both sides of the center of the base cover 2. It has a cuboid structure, 44mm wide, 61mm long, and 12mm high, facilitating positioning and gripping of the base cover 2 during automated production. The loading base 1 is equipped with a sealing skirt 6, which heat-seals breathable paper. The special properties of the breathable paper prevent bacteria and dust from entering, but allow ethylene oxide to pass through. Therefore, during sterilization, ethylene oxide vapor can penetrate the sealed packaging through the breathable paper to kill bacteria and spores inside. Throughout the entire transportation and storage process from sterilization to final use, the breathable paper ensures that the inside of the packaging is not invaded by bacteria and dust, thus achieving sterilization of the pharmaceutical packaging material. A breathable paper sealing platform is provided on the loading base 1 for heat sealing connection of the breathable paper; the base cover 2 is provided with a bypass protrusion groove 12 corresponding to the loading cavity 8. Since the dual-cavity pre-filled syringe assembly is designed to achieve the effect of powder-liquid mixing, a bypass passage is provided at the dual-cavity pre-filled syringe syringe 7, specifically manifested as a protrusion structure on the dual-cavity pre-filled syringe syringe 7. With the bypass protrusion groove 12 provided, the bypass protrusion groove 12 on the base cover 2 will not rub against the bypass passage on the dual-cavity pre-filled syringe syringe 7, thereby avoiding damage to the product. The bypass protrusion groove 12 is 32mm wide, 202mm long, and 1.8mm high, and its position is consistent with the placement position of the base syringe.

[0022] Working process or working principle:

[0023] In use, place the dual-chamber pre-filled syringe syringe 7 in the corresponding slot 10, with the bypass passage protrusion of the dual-chamber pre-filled syringe syringe 7 facing upwards. Then, cover the bottom cover 2 on the loading base 1, so that the buckle protrusion 5 is engaged in the buckle groove 4 to connect the loading base 1 and the bottom cover 2. Then, cover the sealing skirt 6 with breathable paper and tighten it so that the breathable paper does not contact the top of the bottom cover 2. Connect the breathable paper to the sealing skirt 6 by heat sealing. Then, sterilize the dual-chamber pre-filled syringe syringe 7 by ethylene oxide (EO) sterilization. The sterilization channel 3 formed by the assembly of the bottom cover 2 and the loading base 1 can effectively accelerate the gas exchange efficiency and ensure the effect of EO sterilization.

[0024] This invention secures the double-lumen pre-filled syringe syringe 7 within the locking position 10, preventing the product from falling out during transportation due to shaking and vibration. The base cover 2 has ethylene oxide channels at its four corners to reduce ethylene oxide residue and ensure the sterilization effect of the double-lumen pre-filled syringe syringe 7. The overall structural design adopts a symmetrical design, which can effectively reduce human error and ensure the accuracy of mechanical positioning and the efficiency of mechanical suction. The independent locking position 10 structure makes the positioning of the syringe in the loading base 1 more precise, which is conducive to improving mechanical efficiency. The sealed skirt heat-sealed breathable paper forms an overall sealed packaging to prevent the intrusion of dust and bacteria, ensuring long-term storage effect and strong practicality.
