Objective : Constructing Sensor Circuit

Schematic Diagram (Part1 - Sensor)

Honeywell Pressure Sensor 

 Board Mount : Low Pressure Sensors : Basic NBP 

NBPDANN015PGUNV

 The function of this circuit is to amplify and filter the analog signal received from the transducer and then send the signal to ADC to be converted.

Result: Still in progress.

Blood Pressure Cuff (Suntech Medical)


There are two types of BP Cuffs; the disposable BP cuffs and the durable BP cuff.

 

*colour-differentiate design*

•  Disposable BP cuffs
• soft
• single-patient
• to minimize cross-contamination for infection-control conscious hospitals

•  Durable BP cuffs
• long-lasting
• durable
• easy to clean
• general-use clinical applications, line includes

  The reason for this research is to understanding the applications of the BP cuffs and this will give a great example to get a good result when doing a BP measurement.
