Method for producing non-PVC multiple chamber large transfusion bag capable of avoiding water in solid medicine chamber after sterilizing

Abstract

The production process of large non-PVC multiple chamber transfusion bag includes the steps of making bag, filling liquid medicine, sealing and sterilizing, cutting opening in the solid medicine chamber, filling solid medicine, and sealing. The present invention features that before sterilization, the solid medicine chamber is coated with composite aluminum-plastic film to avoid moisture to enter the inside. The said production process can prevent moisture from entering the solid medicine chamber through the non-PVC film of the solid medicine chamber.

Description

technical field [0001] The invention belongs to the field of medicine packaging, and in particular relates to a production method of a non-PVC multi-chamber bag infusion that can avoid water in a sterilized solid medicine chamber. Background technique [0002] The existing single-mouth tube single-chamber large transfusion bag has only one medicine charging chamber, and can only hold a kind of medicine liquid. During production, a single-chamber bag is first made by a bag-making machine, and the medicine is poured into the bag, and then the combined cover is welded. Since the large infusion is generally physiological saline or nutrient solution, it cannot be stored for a long time after being mixed with the therapeutic solid medicine, so the therapeutic solid medicine can be mixed with the large infusion only when in use. The liquid medicine is drawn out and injected into the container of solid medicine, and after it is completely dissolved, it is drawn out from the contain...

AI Technical Summary

Problems solved by technology

Due to the poor water vapor resistance of non-PVC films at high temperatures, during the sterilization process, the concentration of water vapor outside the solid drug chamber is large, while the solid drug chamber is dry gas, so water vapor can easily pass through the non-PVC material that makes up the solid drug chamber. The film enters the solid medicine chamber, and after sterilization, the water vapor condenses into water and stays in the solid medicine chamber. The shelf life of the solid medicine is very short after contact with water, which affects the quality of the medicine.
