Section I: Ostomy Pouch Technical Profile

Definition & Clinical Utility
Ostomy pouches (medical containment devices) are engineered to securely collect and contain bodily waste (urine/fecal matter) for patients with excretory dysfunction caused by:
• Traumatic brain injuries (TBI)
• Spinal cord injuries (ASIA Grade A-C)
• Neurogenic bladder/bowel disorders
• Post-surgical recovery states

Material Science Specifications
Constructed from ISO 10993-certified polymers:

• Polypropylene (PP) matrices (0.5-1.2mm thickness)
• Polyester fiber reinforcement (120-200 denier)
  Key material properties:
  ✓ Biocompatibility (Class VI compliance)
  ✓ Hydrolysis resistance (85% RH, 70°C accelerated aging)
  ✓ Tensile strength >15 MPa (ASTM D882)

Customization capabilities include:
• Anatomical contouring (15°-45° curvature radii)
• Capacity gradients (200-1000 mL)
• Sterile barrier configurations
