Blood Glucose Monitoring Systems—Special Requirements for Visually Impaired or Blind Patients.

• Sufficiently large device with good handling and good haptics

• Sufficiently large display and good display quality (good contrast, antiglare display)

• Sufficiently large test strips with good tangibility

• A large port for the test strips or a suitable alternative (some devices have a drum with test strips, that is, the test strips do not have to be individually inserted into the BGM system)

• A sufficiently large and tactile area on the test strips for applying a drop of blood

An audible alarm when the volume of blood is too small or an erroneous measurement is made

• Acoustically well audible output of the measurement result in the form of speech or tone sequences

• Acoustic output of the last saved readings

• Transfer and analysis of the measured data with a computer-aided documentation and analysis program together with an acoustic output

• Support the handling of the device by voice messages; for error messages additional instructions for problem solving should be provided

• Acoustic support of control measurements

• Acoustic warnings at too low/high readings

• Acoustic trend analysis of measured values
