Objective
The objective of this Design Qualification (DQ) protocol is to ensure that the Implant Mixing Vessel (Jacketed SS) is suitable for its intended use in preparing implant formulations, ensuring compliance with regulatory requirements and quality standards.
Scope
This protocol applies to the Design Qualification of the Implant Mixing Vessel utilized in the production area for the preparation of drug-eluting and biodegradable implants. It covers critical parameters and acceptance criteria as outlined in URS, Annex 11, and Annex 15.
Responsibilities
- Validation Team: Responsible for executing the DQ protocol and documenting results.
- Quality Assurance: Responsible for reviewing and approving the DQ protocol and results.
- Production Team: Responsible for providing access to the equipment and supporting validation activities.
Prerequisites
- Completion of User Requirements Specification (URS).
- Installation Qualification (IQ) must be completed prior to DQ execution.
- Training of personnel on equipment operation and safety protocols.
Equipment Description
The Implant Mixing Vessel is a jacketed stainless steel vessel designed for the mixing of implant formulations. It features temperature control, adjustable mixing speed, and a PLC for process control and data logging.
Test Plan
| Test ID | Procedure | Acceptance | Evidence |
|---|---|---|---|
| T1 | Verify temperature control functionality. | Temperature maintained within specified range. | Calibration records, temperature logs. |
| T2 | Validate mixing speed settings. | Mixing speed matches specified RPM. | RPM measurement logs. |
| T3 | Confirm hold time accuracy. | Hold time matches specified duration. | Time logs, process records. |
| T4 | Review PLC audit trail for data integrity. | Audit trail shows no discrepancies. | PLC audit trail report. |
Detailed Test Cases
Test Case T1: Temperature Control Functionality
Procedure: Set the temperature to the required specification and monitor for stability over a defined period. Record temperature readings at intervals.
Acceptance: Temperature must remain within +/- 2°C of the set point.
Evidence: Temperature log sheets and calibration certificate of temperature probe.
Test Case T2: Mixing Speed Validation
Procedure: Set the mixing speed to the designated RPM and measure actual speed using a tachometer.
Acceptance: Actual speed must match the specified RPM within a tolerance of +/- 5%.
Evidence: Tachometer readings and calibration certificates.
Test Case T3: Hold Time Confirmation
Procedure: Start the mixing process and record the time until the hold time is completed.
Acceptance: Hold time must match the specified duration within +/- 1 minute.
Evidence: Time logs and operator entries in the batch record.
Test Case T4: PLC Audit Trail Review
Procedure: Access the PLC audit trail and verify that all critical parameters are logged without gaps or errors.
Acceptance: Audit trail must show complete and accurate logging of all critical parameters.
Evidence: Extracted PLC audit trail report.
Deviations
Any deviations from the established acceptance criteria must be documented and evaluated for impact on the validation process. A root cause analysis should be performed, and appropriate corrective actions must be taken.
