Negative pressure device for intra-abdominal pressure reduction

Abstract

A device that generates negative extraabdominal pressure (ABDOPRE) for treatment of patients with high intraabdominal pressure was developed. It includes pressure sensors for transducing intraabdominal pressure through an intravesical catheter and negative pressure in the vacuum bell which is placed over the abdomen. By means of a control system, a pattern for reducing IAP is set, according to a clinical protocol. The external negative pressure is generated using a vacuum pump connected to the bell. The system registers the values of interest for the medical history. The system is being tested over ICU patients, registering a satisfactory IAP reduction.
