The fourth week has been wonderful, having different ideas for BP monitor for the villages after brainstorming. As a group it wasn’t easy just to pick one from the rest because most of them seemed nice to us,but through Pugh screening and scoring; we came up with one solution that we have started working on.

Below is some of the suggested solution after brainstorming.

and the detailed diagram for the selected solution after Pugh scoring different views ;

It’s a solution that really meets the design criteria for the project. As the highest criteria is ease of use, the selected solution will allow users to interpret the leading depending on the color of LED which will correspond to the reading (mean arterial pressure) on the display. Despite people will be told the condition of their blood pressure it is also important for them to have the written mean leading (figures) for doctor’s reference in cases of those who will be referred to seek hospitals for medication.

The switch will help users to select option depending on the category of the person they are monitoring, since same reading for either systolic/diastolic can have different interpretation depending on the person being monitored. Some of those considered include children, pregnant women and those with diabetes.

We have managed to understand how the pressure sensor works in conjunction with the instrumentation amplifier.

Finishing the week with the power point presentation on Friday from which we found new ideas from people’s comments such as; rearranging the label for LED’s (from high to low) on interface and using digital display instead of LCD display.
