Portable Aneroid Sphygmomanometer For Children

The Portable Aneroid Sphygmomanometer for Children is a blood pressure measurement device specifically designed for pediatric patients. It employs a mechanical pressure measurement system (liquid-free/dial type) and measures children's blood pressure via auscultation (Korotkoff sound method). This device represents the gold standard for pediatric blood pressure measurement, offering portability, no power requirement, and low cost, making it suitable for clinics, homes, and outdoor medical settings.

This device mainly consists of the following components:

1. Liquid-free pressure gauge: Contains a metal diaphragm capsule (Bourdon tube) and a precision gear transmission mechanism, converting pressure changes into pointer rotation. The dial is usually clearly marked with graduations.

2. Child-specific cuff: Designed for children's smaller arms, the circumference typically ranges from 12 cm to 29 cm, depending on the model (e.g., toddler or older size).

3. Inflation system: Includes a rubber inflation ball, a control knob with a precision deflation valve, and connecting tubing.

4. Portable accessories: Usually includes a zippered carrying case or nylon bag for storing the device and protecting it from impacts.

1. Stable Performance: It adopts a high-quality zinc alloy gauge, which ensures stable performance and long service life.

2. Comfortable Cuff: The soft cotton cuff is specially designed for children, providing comfortable wearing experience.

3. Certified Reliable: With CE/ISO certifications, it meets international medical standards, making it reliable for clinical and home use.

4. Flexible Fit: The optional cuff D ring allows flexible adjustment to fit different arm sizes of children, improving the applicability of the product.

5. Easy Portability: It comes with a durable leather bag for easy storage and portability, suitable for on-site healthcare and outdoor use.

1. Preparation: Have the child sit quietly for 3-5 minutes with back support and feet flat on the ground.

2. Applying the Cuff: Apply the cuff to the right upper arm, with the lower edge 2-3 cm from the elbow crease. The cuff should be tight enough to allow 1-2 fingers to be inserted.

3. Placing the Stethoscope: Place the chest piece of the stethoscope over the brachial artery (inner elbow crease), without pressing firmly.

4. Inflating: Inflate the balloon until the radial artery pulse disappears, then increase the pressure by 20-30 mmHg.

5. Deflating and Measurement: Deflat the balloon slowly (2-3 mmHg/second) and listen for Korotkoff sounds:

Phase I (K1): The first clear pulsation sound heard is the systolic blood pressure.

Phase IV (K4): Standard diastolic blood pressure for preschool children (the sound becomes duller).

Phase V (K5): Adult standard for adolescents (the sound disappears).

6. Recording: Measure 3 times, 1-2 minutes apart, and take the average of the last two measurements.
