slip-on blood pump [ME, slippen, slippery, on] , a plastic mesh device with an attached squeeze bulb, rubber tubing, and pressure gauge, used to help administer large amounts of blood quickly. The plastic mesh slips over the blood bag and exerts pressure on it when the bulb is squeezed. The pressure gauge displays a danger zone, usually marked in red, and indicates pressure limits for safe blood administration. Excessive pressure may damage the red blood cells or may disconnect the primary IV line.
