Abstract

A strain gauge (), a pressure sensor (), and an interventional medical catheter. The strain gauge () comprises a substrate () and at least two sensitive gages () provided on the substrate (), the at least two sensitive gages () being arranged along two mutually perpendicular directions and sharing one ground port (). The pressure sensor () comprises an elastic body () and the strain gauge () provided on the elastic body (). The interventional medical catheter comprises a catheter distal end and the pressure sensor () provided at the catheter distal end. The present application not only saves the trace space for mounting and using the strain gauge () on the interventional medical catheter, facilitating the successful mounting and use of the strain gauge () on the interventional medical catheter, improving the adaptability of the strain gauge (), but also reduces the size of the strain gauge (), thereby shortening the length of the elastic body () of the pressure sensor () and reducing the size of the interventional medical catheter.
