Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a sterilization device for a pre-filled syringe production line. Background Technology

[0002] Pre-filled syringes, also known as pre-sealed syringes or pre-filled needles, are syringes in which medications are pre-filled into polymer or glass tubes in a sterile environment. Before filling with medication, the syringe barrel must be sterilized. In the prior art, a utility model patent with patent application number 201920635969.4 discloses a sterilization cabinet for easy syringe sterilization, mainly composed of a cabinet body, cabinet door, and sterilization chamber. In use, the syringes to be sterilized are placed in the sterilization chamber for sterilization. However, this design has the following problems: because it includes a device for classifying and fixing syringes within the sterilization chamber, it is inconvenient to categorize different types of syringes, making it inconvenient to use and impractical. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sterilization device for a pre-filled syringe production line that allows different types of syringes to be fixed on different fixing mechanisms during sterilization, facilitating the classification and summarization of different types of syringes, and is easy to use and highly practical.

[0004] This utility model discloses a sterilization device for a pre-filled syringe production line, comprising a base plate, a support, a sterilization chamber, and a sealing door. The sterilization chamber is fixedly mounted on the upper end of the base plate via the support. The sterilization chamber contains a chamber, and a loading / unloading port communicating with the chamber is located at the front end of the sterilization chamber. The sealing door is installed outside the loading / unloading port. The device also includes an air inlet mechanism, multiple fixing mechanisms, a rotating mechanism, and a connecting mechanism. The air inlet mechanism is mounted on the base plate, and its output end communicates with the chamber of the sterilization chamber. The air inlet mechanism is used to supply steam into the chamber of the sterilization chamber. The rotating mechanism is mounted on the base plate and the sterilization chamber. Multiple fixing mechanisms are mounted on the rotating mechanism via connecting mechanisms. The rotating mechanism is used to rotate the connecting mechanisms. The fixing mechanisms... It features a fixed mechanism located within the sterilization chamber. When sterilizing pre-filled syringe cartridges, different types of cartridges are first placed on their respective fixed mechanisms. The sealed door is then closed, and hot steam is introduced into the sterilization chamber via the air intake mechanism. This hot steam sterilizes the cartridges within the chamber at high temperatures. After sterilization, the sealed door is opened, and the different types of cartridges are removed from their respective fixed mechanisms and stored separately. This design facilitates the classification and organization of different types of cartridges, making it convenient and highly practical.

[0005] Preferably, the air intake mechanism includes a steam generator, a gas supply pipe, and multiple sets of exhaust pipes. The steam generator is mounted on the base plate, and the output end of the steam generator is connected to the multiple sets of exhaust pipes through the gas supply pipe. All sets of exhaust pipes are mounted on the sterilization chamber, and the output ends of all sets of exhaust pipes are located inside the sterilization chamber. When sterilizing the syringes inside the sterilization chamber, the steam generator is turned on, allowing hot steam to enter the multiple sets of exhaust pipes through the gas supply pipe. Then, the hot steam enters the sterilization chamber through the multiple sets of exhaust pipes to sterilize and disinfect the syringes. This facilitates the sterilization of the syringes.

[0006] Preferably, the rotating mechanism includes an electric turntable and a rotating shaft. The electric turntable is mounted on the base plate, and the rotating shaft is mounted on the rotating end of the upper part of the electric turntable. The rotating shaft is rotatably mounted on the sterilization chamber, and the upper end of the rotating shaft is located inside the chamber of the sterilization chamber. A connecting mechanism is mounted on the upper end of the rotating shaft. When sterilizing the syringes inside the chamber of the sterilization chamber, the electric turntable is turned on, and the electric turntable drives the rotating shaft to rotate, which in turn causes the connecting mechanism to drive multiple fixed mechanisms to rotate, causing the syringes on the multiple fixed mechanisms to rotate, so that the multiple syringes are evenly contacted with hot steam, and the syringes are evenly sterilized; this improves convenience.

[0007] Preferably, the connecting mechanism includes a base plate, a sliding rod, a top plate, and a lead screw. The base plate is fixedly installed on the upper end of the rotating shaft, the lower end of the sliding rod is fixedly installed on the base plate, the top plate is fixedly installed on the upper end of the sliding rod, and the lower and upper ends of the lead screw are respectively fixedly installed on the base plate and the top plate. Multiple fixing mechanisms are installed on the lead screw and the sliding rod. The above arrangement facilitates the fixing of the fixing mechanisms.

[0008] Preferably, the fixing mechanism includes a ring and a locking mechanism. The ring has multiple positioning grooves evenly distributed around its circumference. The ring is mounted on a sliding rod and a lead screw via the locking mechanism, which locks the ring securely to the sliding rod and the lead screw. When sterilizing syringes, multiple syringes of the same type can be placed in the multiple positioning grooves of the same ring, facilitating the fixing of the syringes.

[0009] Preferably, the locking mechanism includes a connecting frame, a sliding plate, bolts, and a threaded tube. The ring is fixedly mounted on the sliding plate via the connecting frame. The sliding plate is slidably mounted on the sliding rod. The sliding plate has a threaded hole, and the bolt is screwed into the threaded hole and tightened against the sliding rod. The threaded tube is screwed into the lead screw. A bearing is provided on the outer wall of the threaded tube, and the threaded tube is rotatably mounted on the bearing, which is fixedly mounted on the sliding plate. When adjusting the height of the ring, first rotate the bolt to disengage it from the sliding rod, then rotate the threaded tube to adjust the height of the sliding plate. The sliding plate adjusts the height of the ring via the connecting frame until the ring is adjusted to a suitable height. Then rotate the bolt to tighten it against the sliding rod, thus fixing the height of the ring. Since the heights of multiple rings can be adjusted, the spacing between multiple rings can also be adjusted. Therefore, the height of multiple rings can be adjusted according to the different heights of the syringes placed on them, making it convenient to use and highly practical.

[0010] Preferably, the sterilization chamber is equipped with a thermometer; this facilitates the monitoring of the temperature inside the sterilization chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when sterilizing syringes, different types of syringes can be placed on different fixing mechanisms, which facilitates the classification and summarization of different types of syringes, making it convenient to use and highly practical.
