Pre-filled syringe packaging box and pre-filled syringe

Abstract

The invention provides a pre-filled syringe, which comprises a syringe cylinder made of plastic and a protective cap covering a conical head of the syringe cylinder, a syringe handle extending out ofthe two radial ends of the syringe cylinder is arranged on the syringe cylinder, and the syringe handle is of a trapezoidal structure and extends outwards in the radial direction of the syringe cylinder. The syringe made of the plastic material can realize the preparation of the large-size pre-filled syringe; the syringe handle arranged on the syringe cylinder comprises two parts located in the radial direction of the syringe cylinder. The syringe handle is provided with the trapezoidal structure, and when the syringe is loaded through the packaging box, the trapezoidal end faces of the trapezoidal-structure syringe handle avoid each other and abut against each other for limiting, so that the internal space of the packaging box is fully utilized, and a maximum space utilization of the packaging box is realized. The invention further provides a pre-filled syringe packaging box.

Description

Technical field [0001] The present invention relates to the technical field of syringes, and more specifically, to a prefilled syringe packaging box and a prefilled syringe. Background technique [0002] At present, the commonly used prefilled syringes are glass prefilled syringes with different specifications such as 0.5ml-20ml, which are used for filling drugs. [0003] Due to the limitation of its material, glass pre-filled syringes can generally only fill 20ml, which cannot meet the filling needs of all drugs, especially large-sized drugs. In addition, during the manufacturing process of glass pre-filled syringes, due to the complicated glass molding process, they are generally difficult to fill. There are processes such as cutting, firing and molding, stress relief, etc., resulting in very high product manufacturing costs, and there have been problems such as glass shavings and tungsten residues that affect the quality of medicines.

Problems solved by technology

[0003] Due to the limitation of its material, glass prefilled syringes can generally only be 20ml, which cannot meet the filling of all drugs, especially large-scale drugs; There are processes such as cutting, firing molding, and stress relief, which lead to very high manufacturing costs, and there have been problems such as glass chips and tungsten residues that affect the quality of medicines

[0004] The handle design of conventional prefilled syringes is generally based on the design points of ISO11040-6, and is designed into a shape such as a circle or a circle with trimmed edges. 100 pieces, but for large-scale syringes, such as 50ml, if the above two designs are still followed, the utilization rate of the packaging box and the packaging honeycomb will be greatly reduced, causing a great waste of packaging materials and reducing the production process. efficiency
