IV production line is an automated industrial equipment system used for the production of medical IV solutions (e.g., glucose injection, sodium chloride injection, etc.), which involves stringent Good Manufacturing Practices (GMPs) and quality control. The following are its key components and processes:
Main production process of IV production line
Preparation of solution
- Equipment: Liquid dispensing tanks, stirrers, weighing systems.
- Steps: Raw materials (e.g., drugs, electrolytes) are accurately weighed according to prescription, dissolved in water for injection and mixed well.
Filtration and purification
- Equipment: Multi-stage filters (e.g. microporous membrane, ultrafiltration system).
- Purpose: Remove impurities, bacteria and pyrogens (endotoxins) to ensure the sterility of the drug solution.
Filling
- Equipment: automatic filling machine (glass bottle, plastic bottle or soft bag filling).
- Key points: filling accuracy (±1% error), avoiding liquid contamination, and the environment needs to meet clean room standards (e.g., ISO Class 5).
Capping/sealing
- Mode: Aluminum cap rolling sealing (glass bottle), heat sealing (soft bag), rubber plug pressure plug.
Sterilization
- Method: Autoclave sterilization (121°C, 15-30 minutes) or water bath sterilization (soft pouch).
- Verification: Heat distribution and heat penetration tests are required to ensure the effectiveness of sterilization.
Quality control
- Items: Visible foreign object detection (light inspection machine or automatic visual inspection), sterility test, pH value, content determination, etc.
Packaging
- Equipments: labeling machine, cartoning machine, coding machine.
- Requirements: accurate labeling information (lot number, expiration date).
core equipment of IV production line
- Liquid dispensing system: stainless steel tank, equipped with CIP (on-line cleaning) and SIP (on-line sterilization) function.
- Filling line: servo motor-driven, accuracy up to 0.1mL; soft bag production line needs to be integrated bag-making-filling-sealing.
- Sterilization cabinet: double case design, distinguishing between clean and non-clean areas.
- Light inspection machine: high-speed camera + AI algorithm to detect particles, fibers and other foreign objects.
- Water treatment system: prepare water for injection (WFI) with resistivity ≥1MΩ-cm.
Key Standards and Certification
- GMP requirements: air cleanliness (filling area needs 100-level laminar flow), personnel protection, equipment verification (IQ/OQ/PQ).
- Regulations: Compliance with the Chinese Pharmacopoeia, FDA 21 CFR Part 211 (USA) or EU GMP (EU).
- Environmental control: Temperature and humidity (usually 20-25°C, 45-65% RH), differential pressure gradient to prevent cross-contamination.
Intelligent
- Data traceability: MES system records production batches, process parameters, and realizes electronic batch records.
- Robot application: AGV transferring materials, robotic arm palletizing.
- Predictive maintenance: monitoring equipment vibration and temperature through IoT to prevent failures.
