SURGICAL FLUID AND BLOOD LOSS MONITOR

摘要

A monitor to provide substantially real-time estimates of fluid absorbed by a patient during an endoscopic surgical procedure. The monitor comprises means for weighing fluid administered to the patient intravenously, as well as that introduced through the endoscope for irrigation purposes. In addition, means are provided for weighing fluid recovered from the patient, the endoscope, and the surgical drapes. The total weight of fluid administered, reduced by subtracting the total weight of fluid recovered, comprises the calculated fluid absorbed. Through manual entries and/or switch settings, computing means maintain totals of fluid administered and fluid collected even as fluid sources are replaced and the fluid collector is emptied. Optional verticality compensation means and anti-rotation devices are included.
