ABSTRACT:
An open loop system for delivering fluid during hysteroscopic surgery. The system includes first and second fluid conduits in fluid communication with the uterine cavity of a patient. First and second measuring devices are provided for measuring the amount of fluid flowing into and out of the uterus. The measuring devices produce electronic signals which are communicated to a controller which uses them to calculate a value reflecting the difference in in-flow and out-flow. This difference is then compared with a preset value; if the preset value is exceeded, the surgeon knows the patient is absorbing too much fluid, and the procedure may be terminated.
