What's the deal with down-the-dropper tubing?

A down-the-dropper is a medical device that is used for the infusion of fluids or the administration of medications. An under-drip tube works by delivering liquid from a container to the patient's blood vessels by gravity or pump force. The infusion bag or medication container is usually suspended higher than the patient's position, and gravity is used to make the liquid flow. Lower dropper is commonly used in medical institutions, hospitals and home care for infusion, blood transfusion, drug administration and other therapeutic processes. Medical staff will set the appropriate number of drops and location of the drip chamber according to the patient's condition and therapeutic needs to ensure accurate delivery of fluids and patient safety.
