The supply of fluids is a major consideration in modern medicine. When fluid is needed, flow regulators are extensively used. But no research or study of flow regulators has yet been performed in Korea. We researched the accuracy of flow regulators that are commonly used in domestic medicine.
We collected and studied the fluid pumped for an hour through four kinds of flow regulators that are used domestic ally. Infusion rates were 10, 20, 30, 40, 60, 80, 100, 150, and 200 ml/hr. For each rate, the height of the fluid between the point of infusion and the outlet was evaluated in 10 cm increments within the range 30 cm to 120 cm.
Among the four products tested, one product injected the fluid three times at the standard height of 80~100 cm, an error of <10%. Two other products injected within the standard range once each, and the fourth product failed to inject within range even once.
The accuracy of flow regulators in the domestic market was exceedingly low.
