Liquid medicine filling system for soft bag infusion products

Abstract

The invention discloses a liquid medicine filling system for a soft bag transfusion product. The system comprises a rack. A soft bag fixing unit, a filling port opening unit, a liquid medicine filling unit, a filing port clamping unit, a soft bag liquid cavity clamping unit and a filling port welding unit are arranged on the rack. By means of the liquid medicine filling system, the side wall of the filling port can be prevented from being tainted with liquid medicine during filling, and the side wall of the filling port and a filling head are prevented from being tainted with the liquid medicine during withdrawal of the filling port, so that the problem that the filling port side wall is contaminated during liquid medicine filling through the filling port is effectively solved, and the reliable heat sealing of the filling port is guaranteed.

Description

technical field [0001] The invention relates to a system for filling liquid medicine into a liquid chamber of a soft bag through a filling port on the liquid chamber. Background technique [0002] In the past, filling the liquid medicine into the liquid cavity on the soft bag packaging container is usually carried out through the mouthpiece provided on the liquid cavity. Since the mouthpiece on the liquid chamber is designed to meet the functions of drug dosing and infusion, its cross-sectional size is usually relatively small. Therefore, using the mouthpiece to fill the liquid medicine has the problems of long filling time and low production efficiency. [0003] For this reason, No. ZL200510025981.6 Chinese patent discloses a side or bottom filling sealed plastic infusion container. The plastic infusion container is provided with a filling port on the soft bag, next to the mouthpiece or next to the hanging bag hole at the tail. The mouth is filled with liquid medicine,...

Problems solved by technology

[0004] A special filling port is provided on the liquid cavity of the soft bag infusion product, although it facilitates the filling of the liquid medicine, but it is necessary to prevent the side wall at the filling port of the soft bag from being contaminated with the liquid medicine when filling the liquid medicine, otherwise it will be It affects the heat sealing effect of the filling port. Therefore, designing an appropriate filling system for filling liquid medicine through the filling port has become a problem that technical R&D personnel need to solve
