Abstract
Recently, interest that intra-abdominal pressure has been increased as change of pathophysiology to critical patients. The intra-abdominal pressure is measured by cystometry what can be available for non-inclusively. However, conventional methods have some problems such as low SNR, weakness of environment temperature, and unsuitable size of sensor. In this paper, a new subminiature pressure sensor module and sensing system are proposed using a sensor of semiconductor type and FPCB. The module is more stable, flexible, and smaller than the conventional catheter. The performance of the developed module is evaluated by various quantitative analysis indexes. The proposed sensor has the high sensitivity and suitable size for measurement of cystometry more than the conventional method. In order to prove efficiency between conventional and proposed method, proposed method compared for sensitivity, fixable, and size. The proposed method will be help measurement of intra-abdominal pressure of patients due to high accuracy and comfortableness.
