How to use the medical double-chamber vacuum sterilization bag sealing machine

Usage of Medical Double-Chamber Vacuum Sterilization Bag Sealing Machines
The operation of a medical double-chamber vacuum sterilization bag sealer involves five key steps: pre-operation preparation, parameter setting, packaging operation, alternating cycles, and finalization with maintenance. The detailed procedure is as follows:

I. Pre-Operation Preparation

1. Equipment Check:
   • Ensure the double-chamber vacuum sealer is placed on a stable surface with at least 1 meter of clearance around it.
   • Check the vacuum pump oil level, integrity of sealing strips, and control panel functionality. Clean dust and debris.
2. Bag Selection:
   • Choose specialized vacuum bags based on medical device characteristics. Ensure bags are dry, undamaged, and match the sealer’s sealing bar dimensions (e.g., 400mm, 600mm).

II. Parameter Setting

1. Time Parameters:
   • Vacuum Time: Dry items: 10–25 seconds; moist items: 25–40 seconds; pure liquids: reduce time (e.g., 10–15 seconds).
   • Sealing Time: Adjust based on bag thickness (1.8–3.8 seconds). Use lower settings for thin bags (e.g., 2 seconds) and higher for thick or foil bags (e.g., 3–4 seconds).
2. Temperature Setting:
   • Use the knob to select low (thin bags), medium (standard bags), or high temperature (thick/foil bags).

III. Packaging Operation (Using the Left Chamber as Example)

1. Placing the Bag:
   • Open the left chamber door, place the bag containing the medical device inside, and ensure the bag opening lies flat on the sealing bar without overlapping the door gap.
   • Press down the bag clamp to secure the opening.
2. Initiating Vacuum Sealing:
   • Close and lock the left chamber door, then press the start button.
   • The vacuum pump begins extracting air. Monitor the vacuum gauge until it reaches the rated level (controlled by a time relay).
   • After air evacuation, the heat-sealing chamber inflates, the heating press frame descends to compress the bag opening, and the heating bar activates for sealing.
   • Once sealing is complete, the vent valve opens, and the door automatically releases.
3. Checking Seal Quality:
   • Remove the bag and firmly pull both sides of the sealed opening to confirm it is secure and airtight.

IV. Alternating Cycle Operation

1. Right Chamber Preprocessing:
   • While the left chamber is sealing, prepare the next batch of medical devices in the right chamber by placing bags and securing openings as described above.
2. Right Chamber Operation:
   • After the left chamber finishes, shift the pressure rod to the right chamber and repeat the vacuum sealing process. Alternate between chambers for continuous operation.

V. Finalization and Maintenance

1. Equipment Cleaning:
   • Power off the machine, clean surface stains and residues, and avoid using sharp tools that may cause scratches.
2. Filter and Seal Replacement:
   • Regularly clean or replace internal filters. Inspect sealing strips for wear and replace them promptly.

Precautions

• Safety: Avoid contact with moving parts (e.g., heating bar, vacuum pump) to prevent burns or pinching.
• Parameter Adjustment: Conduct test runs when using the machine for the first time or with new packaging materials to determine optimal settings (e.g., vacuum time, sealing temperature).
• Troubleshooting: If sealing is inadequate, check for misaligned bag openings, damaged bags, or contact professional maintenance.
