AI Technical Summary

Technical Problem

Existing injection filling equipment lacks a dedicated receiving structure, resulting in dripping medication from the filling head when it is not in use contaminating critical areas of the equipment and increasing the risk of microbial contamination of the drug.

Method used

A filling device including a lifting column and a receiving mechanism was designed. The lifting column is driven by a cylinder to descend, allowing the filling mechanism to extend into the container for filling. After filling is completed, the rotating rod drives the right-angle frame to flip and form a sealed receiving tray to collect the dripping droplets and avoid contamination.

Benefits of technology

It effectively prevents liquid from dripping when the filling head is idle, maintains a sterile environment for the equipment, and reduces the risk of microbial contamination of the medicine.

Abstract

This utility model provides a quantitative filling device for injection solutions, relating to the field of injection solution filling technology. It includes a base, with a storage tank fixedly installed on the upper surface of the base. An impeller pump is installed on one side of the storage tank, and a diverter valve is installed at one end of the impeller pump. In this utility model, when the lifting column descends, the mounting frame drives two rotating rods to move downwards synchronously. By controlling the rotation of the rotating rods, the two right-angle frames flip outwards and open, creating a vertical channel for the dispensing nozzle. After filling is completed, the cylinder lifts the lifting column, and the dispensing nozzle rises and leaves the container. At this time, the rotating rods rotate in the opposite direction, driving the right-angle frames on both sides to flip inwards and close, forming a sealed receiving tray directly below the dispensing nozzle. Finally, the droplets flow through the water outlet holes opened on the side wall of the second inclined groove into the water pipe fixed to the side of the right-angle frame, and are guided to the designated collection point of the equipment, thus solving the problem of drip contamination when the dispensing nozzle is idle.
