![]() The container can be a glass bottle or a plastic bag. The tubing is attached to a container that holds the fluids or medication. It includes plastic tubing with a small needle at the end which can be inserted into the patient’s vein. What is a Micro Drip Set and How Does It Work?Ī micro drip set is a medical device that delivers small amounts of medication or fluids into a patient’s bloodstream. Read on to learn more about micro drip sets, how they work, their various uses in healthcare settings, and the top micro-infusion sets from renowned manufacturers in India. These useful products are designed to deliver small volumes of fluid over an extended period. They are used to administer medication and fluids in small and precise amounts. These findings support the use of mechanical pumps instead of gravity-driven micro-drips to enhance the precision and safety of IV infusions, especially for vasoactive drugs.Micro drip sets, also known as micro-infusion sets, are an essential tool in medical practice. The variable resistance implies nonlaminar flow in the micro-drip model that cannot be easily predicted mathematically. Laboratory simulation of clinical situations with gravity-driven micro-drip infusion sets under wide-open flow conditions revealed that infusion rate (drug and/or volume delivery) can vary widely depending on extrinsic factors including catheter size, fluid column height, and carrier flow. Delivery characteristics of the micro-drip infusion sets from 3 different manufacturers were similar. Volume delivered by the piggybacked micro-drip decreased up to 29.7% ± 0.8% (mean ± SE) as the carrier flow increased from 0 to 1998 mL/min. ![]() Total model resistance of the micro-drip with stopcock and catheter varied with flow rate. The volume of fluid delivered by gravity-driven infusion under wide-open conditions (continuous fluid column in drip chamber) varied 2.9-fold (95% confidence interval, 2.84-2.96) depending on catheter size and fluid column height. To model resistive effects of carrier flow, volumetric infusion pumps were used to deliver various flow rates of normal saline through a carrier IV set into which a micro-drip infusion was "piggybacked." We also compared delivery by micro-drip infusion sets from 3 manufacturers. Fluid volume delivered in 1 minute was measured 4 times with each condition. The roller clamp on the infusion set was in fully open position for all experiments resulting in a continuous column of fluid in the drip chamber. The fluid meniscus height in the bag was fixed (60-120 cm) above the outflow point. ![]() Vertically oriented IV catheters (gauges 14-22) were connected to the stopcock. We conducted laboratory experiments to characterize volume delivery under various clinically relevant conditions of wide-open flow in an in vitro laboratory model.Ī micro-drip infusion set, plugged into a bag of normal saline, was connected to a high-flow stopcock at the distal end. We hypothesized that during this "wide-open" state, drug delivery becomes dependent on factors extrinsic to the micro-drip set and is therefore difficult to predict. When the roller clamp is fully open, flow in the drip chamber can be a continuous fluid column rather than discrete, countable, drops. ![]() Gravity-driven micro-drip infusion sets allow control of medication dose delivery by adjusting drops per minute. ![]()
