Weighing Hood——Large Volume Injection Production

Weighing Hood——Large Volume Injection Production

Large volume injections (LV), commonly known as infusions, refer to liquid sterilized preparations with a volume of 250ml that are directly injected into the vein, and are widely used in clinical practice. It is a branch of injections, usually packaged in glass bottles or plastic bottles or soft bags, without preservatives or bacteriostatic agents. When used, it is continuously instilled into the vein through an infusion set to rapidly infuse drugs or supplement nutrition into the patient's body. , to maintain the body's water, electrolyte and acid-base balance. It plays an irreplaceable role in clinical medicine, especially in the rescue of critically ill patients.

Large-volume injections have stricter quality requirements due to their large dosage and direct entry into the bloodstream. The requirements for certain qualities such as pyrogen, sterility, visible foreign bodies, insoluble particles, pH, osmotic pressure, etc. are stricter than those for small volume injections. It is required that the preparation to sterilization should be controlled within 4 hours. The production process of large-volume injection (infusion) generally includes the preparation of raw and auxiliary materials, processing of concentrated and diluted packaging materials, potting, sterilization, light inspection, packaging and other processes. The cleanliness of the production environment is required to be higher.

Since large-volume injections have high requirements on the production environment, in addition to clean rooms, pharmaceutical factories are also equipped with weighing hoods and laminar flow hoods to meet higher cleanliness requirements.

Therefore, the weighing hood plays a very important role in the production process of large-volume injection, mainly used in the weighing section of raw materials, and also used for the weighing of activated carbon. The weighing hood ensures a sterile environment in the production process of large-volume injections and ensures the quality of the product. Our company has been serving major well-known pharmaceutical factories for many years, with rich experience, professional technology, and trustworthy.
