ALPK2 Aneroid Sphygmomanometer

ALPK2 Aneroid Sphygmomanometer (China)

The ALPK2 generally refers to budget-friendly, Chinese-manufactured aneroid sphygmomanometers built on the widely recognized ALPK2 design standard (originally engineered in Japan). These sets serve as accessible entry-level options for students, home users, and general clinical triage.

Key Technical Specifications

• Measurement Range: 0 to 300 mmHg
• Accuracy Standard: Standard tolerance within ±3 mmHg under routine test conditions
• Manometer Gauge: 50 mm dial with high-contrast scale markings and rear clip for cuff attachment
• Tubing System: Standard 2-tube inflation system
• Cuff & Bladder: Washable nylon or cotton cuff featuring Velcro fasteners and index marking for standard adult arms (22–32 cm)
• Air Valve: Standard chrome-plated brass air deflation valve with screw-type micro-release

Operational Considerations

• High Cost-Efficiency: Provides a functional manual BP apparatus at a lower price point than Japanese-manufactured units, making it ideal for high-volume commercial supply and medical student practice kits.
• Pre-Use Verification: Requires standard zero-point verification before measurements to ensure the needle rests accurately within the zero box on the dial face.
• Maintenance & Storage: Best maintained by regularly checking rubber components for dry rot, ensuring valves remain free of debris, and storing in a protective zip pouch when not in use.

Calibration Protocol

Aneroid blood pressure monitors should undergo formal calibration testing every 6 to 12 months, or immediately after being dropped.

• Connect to Reference: Link the aneroid gauge in parallel with a certified reference manometer (such as a master gauge or mercury standard) using a Y-connector (T-tube).
• Pressurize: Inflate the system slowly to 300 mmHg.
