At the end of the 20th century, another method of suction was developed in which a valve was constructed at the top of the jar and a small hand-operated pump is attached so that the practitioner could suction out air without relying on fire (thus avoiding some hazards and having greater control over the amount of suction). Both glass and plastic cups were developed, though the plastic ones are not very well suited to moving along the skin once in place, as the edges are not entirely smooth and the strength of the cups is limited. The modern name for cupping is baguanfa (suction cup therapy).
