Fluid management / distension pump system
A dual-circuit infusion/aspiration pump that distends the cavity with a liquid medium (saline in arthroscopy; glycine, sorbitol-mannitol or saline in hysteroscopy) at controlled pressure and flow, monitoring inflow versus outflow volume in real time; distinct from the already-catalogued CO2 insufflator, which uses gas, not liquid.
How it is used
Distends the uterine cavity or the joint to allow endoscopic visualization during hysteroscopy or arthroscopy.
Clinical tip
Glycine is the most commonly used distension medium in hysteroscopy for its low viscosity and compatibility with monopolar electrosurgery, but excessive intravascular absorption can cause severe hyponatremia and acute pulmonary edema, hence the critical importance of this pump's pressure and fluid-balance control.
