Abstract
A pressure sensor for a dialysis machine, the sensor having a body and a sensing surface, the sensor surface configured to detect the pressure of a fluid across an elastic membrane, the sensor in use generating a vacuum between the sensing surface and the membrane so as to draw the membrane into contact with the sensing surface, wherein the elastic membrane is further retained in use between a sealing surface on the dialysis machine and a membrane engaging surface on the body of the sensor.
