The manual aneroid sphygmomanometer is a traditional manual blood pressure measurement device that uses a mechanical aneroid gauge instead of a mercury column. Blood pressure is measured manually by inflation and auscultation with a stethoscope. Versions containing Latex (natural rubber latex) components typically refer to a latex inflation system (bladder/inflation ball) that offers excellent elasticity and durability.
This sphygmomanometer features an aluminum alloy gauge head, a measurement range of 0 to 300 mmHg, an accuracy of ±3 mmHg, and a 2 mmHg scale division, ensuring clear and consistent blood pressure measurements. The soft cotton cuff is comfortable to wear, and the latex bulb and air bladder are durable and operate smoothly.
This blood pressure monitor features a lightweight and compact design for easy daily carrying and field use. It comes with a durable leather carrying case for secure storage and transport, making it ideal for mobile healthcare and various daily health monitoring scenarios.

Product Components
1. Liquid-free pressure gauge: Circular mechanical dial with a white background and black graduations; pointer indicates pressure value.
2. Latex inflation ball: Olive-shaped or handheld, with an adjustable metal deflation valve at the bottom.
3. Latex air bladder: Located inside the cuff, used to compress the artery.
4. Cuff: Reusable nylon/cotton sleeve with a scale (for indicating arm circumference).
5. Carrying pouch: Typically includes a zippered carrying pouch (usually made of nylon or synthetic leather).
Advantages
Stable Performance: It uses a high-quality aluminum alloy gauge that guarantees stable measurement and long service life.
Comfortable Wearing: The soft cotton cuff offers a comfortable fit during long periods of use.
Certified Quality: With CE and ISO certifications, it complies with international medical standards and is reliable for both clinical and home use.
Flexible Adjustment: The optional D-ring on the cuff allows flexible fitting for different arm sizes, enhancing overall usability.
Excellent Portability: Light and compact structure with a durable leather bag makes it easy to store and carry, ideal for on-site healthcare and outdoor applications.
Usage Precautions
1. Latex Allergy Risk: Products containing latex components are not suitable for people with latex sensitivities. Latex-Free alternatives (made of PVC) are available on the market.
2. Regular Calibration: Professional calibration is recommended every 1-2 years to ensure ±3 mmHg accuracy.
3. Deflator Control: The deflation rate is precisely controlled via a screw valve; excessive deflation will lead to inaccurate readings.
4. Cuff Position: The center of the cuff should be aligned with the brachial artery, and the lower edge of the cuff should be 2-3 cm from the elbow crease.
