About Us
Sterile mucus specimen traps are single‐use, aseptic devices engineered to collect and transport respiratory secretions—such as sputum, tracheal aspirates, or bronchoalveolar lavage fluid—in clinical and laboratory settings. Designed for compatibility with suction or catheter systems, these traps safeguard specimen integrity by preventing backflow and environmental contamination. Their transparent housings enable immediate visual assessment of sample volume and quality before laboratory processing.
| Feature | Description | Typical Specification |
|---|---|---|
| Volume Capacity | Maximum fluid volume the collection chamber can hold | 30 mL, 60 mL, 100 mL |
| Material | Biocompatible, medical‐grade plastics with high chemical resistance | Polypropylene; PP–PE blends |
| Closure System | Secure, leakproof cap or flange to seal the specimen | Screw‐cap with O‐ring gasket |
| Connection Port | Inlet and outlet fittings for seamless attachment to suction tubing | 6 mm barbed inlet; Luer‐lock outlet |
| Filter Element | Integrated hydrophobic or HEPA filter to prevent aerosol backflow | 0.2 µm hydrophobic membrane |
| Sterilization | Terminal sterilization method to ensure sterility | Ethylene oxide (EO) or gamma irradiation |
| Stand‐alone Base | Built‐in stand or bracket for upright positioning on flat surfaces | Fold‐out feet or molded base |
Key Advantages:
Aseptic Integrity: One‐way valves and hydrophobic filters block contamination of suction lines and environment.
Visual Monitoring: Transparent walls and graduated markings allow precise measurement of mucus volume prior to dispatch.
Ease of Use: Quick‐attach fittings and ergonomic shape enable rapid setup and disposal without specimen loss.
Laboratory Compatibility: Standardized outlet fittings ensure direct transfer into specimen cups or vacutainers.
Clinical Applications:
Ideal for bronchial hygiene management in critical care units, respiratory therapy departments, and operating rooms, these traps collect sputum or aspirates for microbiological culture, cytology, viral PCR assays, and biochemical analyses. They are indispensable during tracheal suctioning of ventilated patients, bronchoscopy procedures, and emergency airway clearance.
By combining leakproof design, integrated filtration, and clear volume marking, sterile mucus specimen traps provide a reliable bridge between the patient bedside and the diagnostic laboratory—streamlining sample collection while maintaining the highest standards of safety and specimen quality.
