[The design of a multi-parameter patient monitor]

This paper describes the software and hardware design of a multi-parameter patient monitor which is able to measure ECG, heart rate, blood pressure, breath rate, body temperature and oxygen saturation non-invasively. The instrument uses embedded industry control module as its main controller and 9" CRT as its display. Several OEM modules are utilized in the design, such as ECG module, blood pressure module and oximeter module. This design strategy has the features of reliable performance, easy maintenance, and short developing period.
