Custom Machine Vision Inspection Systems for Medical Devices
Automated Inline Inspection for Medical Device, Diagnostic and Life Science Manufacturing
Medical devices and diagnostic components vary considerably in geometry, material, surface properties and manufacturing process. Their inspection requirements are equally diverse: components must be assembled completely, meet defined geometrical requirements, be free from relevant visible defects and match the intended product configuration.
OCTUM develops custom machine vision and automated optical inspection systems for products that are not covered by a standard inspection solution. Examples include blood collection tubes, eye-drop bottles, dialysis filters, medical containers, tubs, trays, cleanroom bags, calibrators and other components used in medical device manufacturing, diagnostics and life science applications.
Each inspection solution is engineered around the product, relevant quality characteristics, known defect types, material and surface properties, product variants, target throughput and conditions within the assembly, production or packaging line.
Depending on the application, defective units can be detected within the available process window and rejected automatically. Inspection results can be documented, linked to product, lot, work-order or process data and made available for quality assurance, traceability and process analysis.
OCTUM USA provides regional coordination, technical support and service for customers across the United States, Central America and South America, backed by OCTUM's machine vision, software and application expertise in Germany.

OCTUM transfers proven machine vision concepts to new products and manufacturing processes. Cameras, lenses, lighting, software, product handling, machine communication and reject handling are designed as one coordinated inspection system.
Inspecting Blood Collection Tubes
Blood collection tubes can be inspected without contact for geometrical characteristics and visible quality defects. Depending on the product and process, inspection tasks can include:
- Inner and outer diameters
- Roundness and concentricity
- Radial flash
- Under- and over-molding
- Short shots and incompletely molded areas
- Contour deviations
- Visible damage
The achievable inspection performance depends on factors including material, transparency, color, defect size, product handling, target throughput and required image resolution.
Inspecting Eye-Drop Bottles and Dropper Inserts
For eye-drop bottles, the machine vision system can verify whether the dropper insert and cap are present, whether the correct variants have been used and whether the components have been assembled correctly.
Possible inspection characteristics include:
- Presence of the dropper insert
- Correct dropper variant
- Insertion depth and complete seating
- Angular misalignment of the dropper relative to the bottle
- Correct cap assembly
- Position and orientation of components
- Visible assembly and surface defects
The inspection station can be positioned immediately after the relevant assembly or closing step so that defective units are identified early in the manufacturing process.
Inspecting Dialysis Filters
Dialysis filters and associated components can be inspected for geometrical characteristics, assembly conditions and visible surface features.
Depending on the filter design, possible inspection tasks include:
- Position, contour, length and diameter
- Geometry and shape deviations
- Visible surface defects
- Presence and position of the fiber bundle
- Component completeness
- Correct assembly and orientation
The areas that can be made reliably visible are evaluated using the actual filter, materials and component handling conditions.
Inspecting Medical Containers and Bottles
OCTUM develops application-specific inspection systems for medical and pharmaceutical containers made from glass, plastic or metal.
Typical inspection tasks include:
- Product and variant verification
- Presence and assembly of caps, tabs, closures and other components
- Component position and orientation
- Detection of visible scratches, cracks, breakage and stains
- Detection of mechanical defects such as damaged clips
- Contour, geometry and dimensional inspection
- Print, human-readable text and code verification
Reflective, transparent or structured surfaces place particular demands on lighting, lenses and image acquisition. These factors are considered during the feasibility assessment.
Inspecting Tubs, Trays and Syringe Nests
Tubs, trays and syringe nests can be inspected for completeness, component loading and visible packaging characteristics before subsequent processing or packaging steps.
Possible inspection tasks include:
- Completeness within the syringe nest or tray
- Correct number and arrangement of components
- Product position and orientation
- Presence and position of a Tyvek cover
- Visible seal characteristics
- Print on the tub, tray or nest
- Variable text and 1D and 2D codes
Optical inspection evaluates visible sealing characteristics. It does not replace physical leak testing, seal-integrity testing or seal-strength testing.
Other Medical and Diagnostic Applications
Additional custom inspection solutions can be developed for products including:
- Cleanroom bags
- Pharmaceutical and medical films
- Calibrators
- Filter cartridges and filter components
- Web materials and film products
- Closures and assembly components
- Diagnostic consumables
- Medical containers and packaging components
The decisive factor is not the product designation alone, but the specific inspection requirement. OCTUM works with the manufacturer to evaluate which quality characteristics can be detected optically and how the inspection can be integrated reliably into the production process.
Surface, Defect and Contamination Inspection
Depending on the material, contrast and defect characteristics, the camera system can detect scratches, cracks, breakage, flash, deformation, foreign particles, deposits, stains and other visible deviations. The achievable detection limit is evaluated for the specific application.
Print, OCR, OCV and Code Verification
Printed information, lot numbers, serial numbers, manufacturing dates and expiration dates can be read or compared with defined reference data. 1D and 2D codes can also be decoded and checked for content, readability and association with the intended product configuration.
Engineered Around the Product, Defect Characteristics and Manufacturing Process
A reliable inspection solution results from the coordinated interaction of image acquisition, product handling, inspection software, machine communication and reject handling.
During system design, OCTUM considers factors including:
- Product geometry and accessible inspection surfaces
- Material, color, transparency and reflectivity
- Relevant defect characteristics and required detection limits
- Tolerances and measurement requirements
- Product variants and format changes
- Target throughput and available inspection window
- Installation space and environmental conditions
- Triggers, encoders and other process signals
- Interfaces to the PLC, machine and higher-level systems
- Pass/fail decisions and reject handling
- Operator interface, recipe and format management
- Storage and transfer of inspection data
- Maintainability, serviceability and future expansion
Different camera technologies, lenses, lighting methods and evaluation algorithms are used depending on the application. The selection is based on the actual product and the defect characteristics that need to be detected.

Machine Vision for FDA-Regulated Medical Device Manufacturing
In regulated medical device manufacturing, it may not be sufficient simply to classify products as acceptable or defective. Depending on the intended use and the manufacturer's quality processes, inspection results, system changes, user actions and relevant production data may also need to be documented in a traceable manner.
For manufacturers subject to U.S. medical device requirements, the FDA Quality Management System Regulation under 21 CFR Part 820 is particularly relevant. The QMSR incorporates ISO 13485:2016 by reference as the foundational quality management system standard for medical devices.
When an inspection system creates or manages quality-relevant electronic records or electronic signatures required by applicable FDA regulations, requirements arising from 21 CFR Part 11 may also apply, depending on the intended use and the manufacturer's recordkeeping processes.
For products distributed internationally, additional requirements such as the European Medical Device Regulation, the In Vitro Diagnostic Medical Devices Regulation or other national regulations may also need to be considered.
These requirements apply to the manufacturer and its quality management system. An inspection system alone does not establish FDA or regulatory compliance. However, OCTUM can provide technical functions and documentation that support the manufacturer's quality, qualification and validation processes.
Depending on the project, possible system functions include:
- Role-based user and access management
- Audit trail
- Controlled recipe and product configuration management
- Version and change history
- Storage of inspection and event data
- Product, lot and work-order assignment
- Data integrity and traceability
- Interfaces to PLCs, MES and higher-level systems
- Documentation supporting qualification and validation
The specific system configuration depends on the intended use, product risk, operational processes, quality management system and validation strategy of the manufacturer.
2. Evaluate Technical Feasibility
For new or demanding applications, OCTUM examines known-good parts, known-defect parts and, where applicable, limit samples under realistic conditions. Image quality, feature contrast, defect detectability, camera technology, lenses, lighting and evaluation methods are assessed.
The results provide a technical basis for the inspection concept and help define achievable performance for the relevant defect characteristics.
3. Design and Integrate the Inspection System
Based on the results, OCTUM develops a coordinated concept for image acquisition, inspection software, mechanics, product handling, operator interaction, reject handling, interfaces and data flow.
The inspection system is engineered for integration into the intended machine or production line.
4. Commissioning and Long-Term Support
Following installation and integration, OCTUM supports commissioning, system optimization, operator training, new product configurations, additional inspection characteristics, maintenance and long-term operation.

Technical feasibility is evaluated for the specific product and the relevant defect characteristics.
Does Every Medical Device Require a Completely New Inspection System?
Not necessarily. Proven camera technology, software modules and system concepts can be reused and configured for specific products, depending on the application. However, product handling, lighting, lenses, inspection programs, interfaces and documentation functions are adapted to the individual inspection requirement.
Is 100% Inline Inspection Possible?
Depending on the product, inspection characteristics, target throughput and machine design, the system can be engineered to inspect every unit produced. The detectability of each defect characteristic and the achievable inspection performance must be demonstrated for the specific project.
Can Transparent or Reflective Medical Devices Be Inspected?
Yes. Transparent and reflective products can generally be inspected optically. However, these surfaces require a specially adapted lighting, lens and image-acquisition concept. Whether the relevant defect characteristic can be made visible with sufficient contrast should be evaluated using actual samples.
Can Dimensions and Geometrical Characteristics Be Inspected?
Yes. Diameters, lengths, distances, contours, angles, roundness and other geometrical characteristics can be measured without contact. Resolution, tolerances, part presentation, calibration and measurement system capability are considered for the specific application.
Can Visible Contamination and Surface Defects Be Detected?
Depending on the material, contrast, defect size and image-acquisition conditions, the system can detect foreign particles, stains, scratches, cracks, flash, breakage and other visible deviations. The achievable detection limit is determined for the specific project.
Can the Inspection System Be Integrated into an Existing Production Line?
Yes. OCTUM integrates machine vision and AOI systems into both new equipment and existing production lines. Available installation space, part handling, line speed, control interfaces, operator interaction, data requirements and reject handling are considered during system design.
When Is a Feasibility Study Recommended?
A feasibility study is particularly useful for new products, small or low-contrast defect characteristics, transparent or reflective materials, tight tolerances, demanding production speeds or limited installation space. It provides a reliable technical basis for decision-making before implementation.
