Blood Glucose Meter

Blood Glucose Meters (BGM) are battery powered portable medical devices which are used to measure the glucose levels within a blood sample. The majority of these meters operate by measuring a current (typically in the  range of nA’s) which varies based on a reaction between the blood sample and an enzyme which is present on the test strip.  The current is then converted to a voltage using a trans-impedance amplifier which is then amplified to a level which may be measured using an analog-to-digital converter. This voltage is then processed to provide the user with a reading which is displayed on the meter and may also stored for retrieval at a later time.

Blood Pressure Monitor

The health benefits and early warning signs attainable through regular blood-pressure monitoring are well known. These portable pieces of equipment require precision analog measurements along with precise control functions to ensure the system operates correctly and with maximum efficiency.  Oscillometric blood-pressure monitoring systems operate by carefully inflating an arm cuff until the blood flow is restricted and then deflated allowing the blood to flow again, by monitoring oscillations within the artery it is possible to extrapolate systolic, diastolic and mean arterial pressures.  The pressure cuff is controlled using a small electric air pump, electronically operated air valve and a pressure sensor.
