Social workers use practice experience to inform scientific inquiry and use research evidence to inform practice. As with the social work practitioner, social work educators also experience ethically-based challenges in relation to EBP. NASW and CSWE clearly promote an evidence-based focus in both social work practice and education.
Some drug infusion pumps are external and can be used in the hospital and at home. Others are surgically implanted into the patient. Drug infusion pumps can be used to deliver a number of drugs and fluids. Some of the more common uses include: 1  providing high-risk patients with critical fluids and nutrients. 2  delivering antibiotics (the majority of external drug infusion pumps administer antibiotics). 3  delivering pain relieving drugs -- pumps administering these types of drugs are often called pain pumps or anesthetic infusion pumps.
A drum pump, also called an oil drum pump or oil barrel pump, is used to remove liquids from barrels, drums, tanks, and intermediate bulk containers (IBCs). Drum pumps consist of an intake tube, a pumping mechanism, an outflow hose, and often a nozzle of some type. Drum pumps come in many forms from the rotary type to a variety of other styles including lever, piston, siphon, double diaphragm, electric, and air. The 55 gallon drum pump is most common, because it is a standard drum size. The intake valve of a 55 gal drum pump is inserted into a bung hole, and the pump sits atop the barrel. The siphon drum pump, lever-action, and rotary drum pump, due to their simplicity, are the most commonly used type of 55 gallon drum pumps. An electric barrel pump reduces the time required to dispense liquids.
