Abstract
A disposable blood pressure monitor comprising an elongated tubular structure, adapted on one end to place its interior in direct communication with a fluid system to be monitored. A flexible tube shaped membrane is received within the tubular structure, separating the tubular structure into first and second chambers and a gauge assembly engages the other end of the tubular structure, to place the interior of the other chamber of the tubular structure in a pressure transfer communication with the fluid system to be monitored. The gauge assembly comprises a plug, a pressure measuring device mounted to the plug, a sensing tube extending through the plug and communicating with the pressure measuring device and a fluid filled sack member secured to the sensing tube. The sack member communicates with the pressure measuring device through the sensing tube and engages the inner wall of the flexible tube shaped membrane to place the gauge in a pressure responsive position with the fluid system to be monitored.
