• AUTOMATIC LIQUID STOPPING • DOUBLE-CHAMBER DRIP CHAMBER OF PC AND PVC PRODUCT PARAMETERS ACCESSORIES DESCRIPTION UNDER THE ACTION OF ATMOSPHERIC PRESSURE, THE LIQUID IN THE BOTTLEFLOWS INTO THE THINNER INFUSION HOSE TO FORM HYDROSTATIC PRESSURE.WHEN THE HYDROSTATIC PRESSURE IS GREATER THAN THE VENOUSPRESSURE, THE LIQUID IN THE BOTTLE FLOWS INTO THE VEIN. WHEN THELIQUID MEDICINE IS NEARLY EXHAUSTED DURING INFUSION, UNDER THEEFFECT OF THE SURFACE TENSION OF THE FILTER MEMBRANE IN THEAUTOMATIC FLUID STOPPAGE DEVICE, THE VENOUS PRESSURE ANDGRAVITATIONAL PRESSURE FORCES WITHIN THE INFUSION TUBE WALL AREBALANCED WITH THE TENSION OF THE FILTER MEMBRANE. THAT IS, UND ERTHE COMBINED FORCE OF ATMOSPHERIC PRESSURE, HYDROSTATIC PRESSURE AND HUMAN VEINS, THE LIQUID MEDICINE REMAINS STILL INTHE INFUSION SET, ACHIEVING THE FUNCTION OF AUTOMATIC FLUIDSTOPPAGE.
