MST Medical Compression Stocking Tester

I. Product Overview

The MST Medical Compression Stocking Tester is a specialized instrument designed to evaluate the compression performance, elasticity, and durability of medical-grade compression stockings. It ensures compliance with healthcare standards by quantifying pressure distribution, hysteresis loss, and fabric resilience under repeated stress cycles.

• Type: Automated textile testing system for medical compression wear
• Key Metrics:
  • Compression Pressure Range: 15–50 mmHg (adjustable)
  • Pressure Accuracy: ±1 mmHg (ISO 13994 standard)
  • Elastic Recovery Rate (%): 95% min (AATCC 139)
• Sample Size: 30×300mm (calf segment simulation)
• Applications: Garment manufacturing, clinical research, quality assurance

II. Technical Specifications

III. Key Features

• Dual Test Modes:
  • Static Mode: Measures initial compression pressure
  • Dynamic Mode: Simulates walking motion (5–120 steps/min)
• Advanced Analysis:
  • Pressure gradient mapping (ankle to knee)
  • Hysteresis loss calculation (ΔP vs cycles)
  • Real-time fabric strain visualization
• Compliance:
  • ISO 13994 (Medical compression garments)
  • AATCC 139 (Textile elasticity)
  • YY/T 0561 (Chinese medical hosiery standard)

IV. Applications

1. Quality Control: Batch testing of graduated compression stockings
2. R&D: Developing pressure-mapping hosiery for lymphedema
3. Clinical Research: Validating therapeutic compression levels
4. Forensic Analysis: Evaluating garment failure in patient care

Standard Operation Workflow:

1. Sample Preparation: Cut 30×300mm specimens from sock/tube
2. Clamping: Secure sample in vacuum chuck with 20 N force
3. Parameter Setup: Select test mode (static/dynamic) and cycle count
4. Testing: Run pressure cycle (10–100x) with real-time monitoring
5. Analysis: Generate pressure distribution heatmaps

Safety Precautions:

• Avoid contact with sharp clamps during loading
• Use medical-grade gloves when handling used samples
• Calibrate sensors monthly per ISO 17025
