I think this project you can to design it by your self
Ok this is my idea
1- you need transducer to convert blood pressure to frequency "this freq change with blood pressure change"
2- you can measure this freq by using microcontroller
3- convert this measuring freq to equaled pressure
4- display the out by LCD
Circuit Cellar magazine and TI sponsor's the msp430 design contest, look the following link and send e-mail for the author, he will send the files for You...
