The Equivalence between Row and Column Linear Regression
A pressure infusor for introduction of fluids into the human body. Two sheets of polyurethane overlie each other and are continuously sealed to form an air-inflatable bladder. A strip of polyurethane projects from one vertical margin of the bladder to wrap completely around the liquid-filled bag. A narrow elongated strap is centrally attached to one margin of the infusor and is long enough to wrap completely about the infusor with a bag enclosed. Velcro strips are secured to the strap so that it can be fastened upon itself.
