High polymer material pre-filled syringe with needle and forming process of high polymer material pre-filled syringe

Abstract

The invention belongs to the technical field of medical packaging, and particularly relates to a high polymer material pre-filled syringe with a needle and a forming process thereof.The high polymer material pre-filled syringe with the needle comprises a needle cylinder, an injection needle and an injection needle protective cap, the needle cylinder is made of cycloolefin polymer, the injection needle is embedded in the upper portion of the needle cylinder, and the injection needle protective cap is arranged on the lower portion of the needle cylinder. And the needle cylinder is integrally formed with the needle cylinder. The technological process comprises the steps of raw material dehumidification, injection molding, needle silicification, protective cap installation, needle cylinder spraying silicone oil, paper sealing and bag sealing, boxing, sterilization and analysis and assembly warehousing. The high polymer material pre-filled syringe with the needle is small in specific gravity, light in weight, high in non-breaking strength, suitable for 27G or 31G needle heads, very suitable for hyaluronic acid and other high-viscosity medical beauty products, attractive and high-grade in product, free of explosion risk, deeply loved by medical beauty pharmaceutical enterprises and suitable for the medical packaging fields of vaccines, biology, medical beauty and the like.

Description

technical field [0001] The invention belongs to the technical field of medical packaging, and in particular relates to a polymer material prefilled syringe with a needle and a molding process thereof. Background technique [0002] It has been 20 years since the birth of prefilled drug syringes, mainly made of glass. Glass prefilled syringes are mainly divided into prefilled syringes with needles and prefilled syringes without needles. Prefilled syringes with needles have lower drug residues, no need to install needles for injecting drugs, and can be used immediately after unpacking, which is safer, faster and more convenient. It is widely used in emergency rescue, field medical care, and expensive drug packaging. Glass prefilled syringes have defects such as glass peeling, heavy metal tungsten residue, unstable pH value, protein adsorption, silicone oil accumulation contaminating drugs, high specificity and easy breakage, high viscosity and high pressure injection with risk...
