Description

Technical Field

[0001] The utility model relates to the technical field of loading infusion medicine bottles, in particular to a mechanism for transferring an empty sterilizing tray box of infusion medicines. Background Art

[0002] Infusion is one of the most widely used and important treatment methods in clinical practice. Infusion is generally administered intravenously, and the requirements for sterility are particularly high. The sterility of infusion drugs is mostly achieved by terminal sterilization in a water bath sterilizer. In addition to the performance of the sterilizer, the loading method of infusion drugs is particularly important to achieve the sterility assurance capability of infusion products. At present, most infusion drug manufacturers use two methods to load infusion drugs. One is to put the drugs into sterilization trays, and the sterilization trays are stacked layer by layer. The stacked sterilization trays are automatically controlled by the program to enter and exit the water bath sterilizer through automatic rails. The sterilization trays of this method are large in size (commonly known as large trays), and are mostly suitable for production lines of infusion drugs with a single specification and a single packaging form. The other method is to place the drugs into sterilization trays, and then push the sterilization trays layer by layer into the drawer-type sterilization cart, and then move the sterilization cart in and out of the water bath sterilizer via tracks. The sterilization trays in this method are smaller in size than the stacked sterilization trays (commonly known as small trays), and are mostly suitable for production lines that produce a variety of specifications, complex sterilization processes, and a variety of packaging forms, and where infusion drugs need to be changed frequently.

[0003] The Chinese patent application "Fully automatic bag loading equipment for stand-up bags", application number: CN201711174167.X has solved the full process automation technology of fully automatic loading of infusion drugs, automatic stacking and splitting of sterilization trays in the water bath sterilizer mode using automatic rails to automatically enter and exit the sterilization trays.

[0004] Most of the production models that adopt the sterilization tray box pushed into the drawer-type sterilization cart still use manual labor to take the sterilization tray box out of the drawer-type sterilization cart, and then load the infusion drugs into the sterilization tray box manually or semi-manually and semi-mechanically, and then manually push the sterilization tray box loaded with infusion drugs into the drawer-type sterilization cart, which is very labor-intensive and inefficient.
