Aneroid Sphygmomanometer with Stethoscope, Japanese, Model SA-501
A manual device for measuring systolic and diastolic blood pressure by inflating a cuff around the upper arm and assessing blood flow through the brachial artery by auscultation.
Components
- Cuff for placement around the arm.
- Inflation bulb (pump) to inflate the cuff.
- Analog gauge (manometer) to display readings.
- Stethoscope for listening to pulse sounds during measurement.
How it works
The device determines blood pressure by occluding the brachial artery with an inflated cuff and then slowly releasing air while listening for pulse sounds to identify systolic and diastolic pressures.
- Seat the patient upright and comfortably.
- Position the cuff with its upper edge about 1 inch above the antecubital crease.
- Secure the cuff snugly using the attached strap.
- Inflate the cuff to a level above the patient’s systolic pressure.
- Release air slowly while listening with the stethoscope.
- Record the first audible beats as the systolic pressure.
- Continue deflation until the sounds are no longer heard; record this as the diastolic pressure.
Benefits
- Accurate measurement of blood pressure.
- Simple operation, suitable even for new users.
- Cost-effective option.
Safety and care
- Use only for its intended medical purpose.
- Do not use if damaged or soiled.
- Store in a clean, dry environment.
Disposal
Follow safe medical waste procedures when discarding the device and place it in a closed container to prevent contamination.
