Abstract
En innretning for måling av trykket i en infusjonsslange (12) omfatter en trykksensor (20), et hus (14) med minst et kammer (16) begrenset på en side av en deformerbar mem- bran i kontakt med veggen til infusjonsslan- gen og i hvilken sensoren er anordnet. Et fluid (24) er anordnet mellom membranen (18) og sensoren (20) . Fluidet er en ikke-væske og har et poissontall som er større eller likt 0,49 og en momentan elastisitetsmodul mindre enn 10 MPa slik at responskurven til den nevnte sensor blir lineær. Anvendelse på infusjonsapparater, spesielt bærbare.
