The humble suction cup, otherwise known as a sucker, was in use as early as 300 BC, when it is believed to have been used as a medical implement. Gourds were used as suction devices to pull “bad blood” out of patients who were suffering from illness or disease. While the medical efficacy of this may be in doubt, the fact that these were functioning suction cups is not. Over the years, suction cups have evolved and the Convum suction cups available today are the result of this evolution. Moreover, the principle behind suction cups has been adapted and turned from being a passive implement that creates a partial vacuum to Convum vacuum pads that use active air compressors to create a continuous vacuum. Suction cups should not be unfamiliar to most people, as they are present in most households in one form or another. The simplest example of modern suction cups are the round rubberized suckers that can be stuck onto windows and other glossy surfaces, and usually feature hooks to facilitate the storage of items by hanging them off the suction cups. Another form that suction cups have taken that should be familiar to most people is the toilet plunger, which is essentially a stick with a big suction cup at the end that can be used to unstick simple clogs in toilet plumbing. Vacuum pads, on the other hand, are much more complex pieces of equipment that also have a greater variety of uses than suction cups. Unlike suction cups, which can be used simply by pressing them firmly to a surface and pushing air out the side so that a partial vacuum is formed, vacuum pads actively create that vacuum by continuously pumping air out. This is useful for a few reasons, the first of which is the absence of a need to press down on the pad in order for it to adhere to a surface, and the second is that this allows the vacuum pad to adhere to a greater variety of surfaces and not be limited only to glossy surfaces. Of course, in order to create the continuous flow of air resulting in the vacuum, an air compressor is required that pumps air through the vacuum pad. This requires energy and vacuum pads are usually only found in factories and manufacturing plants where they are part of the production process and where this energy usage is outweighed by the profits generated from the products. One of the more innovative uses of vacuum pads has been the adoption of vacuum pads by a confectionary as a means of handling fragile breads without having to apply any pressure to the breads. There are a great many uses for Convum suction cups and Convum vacuum pads, which is an elegant illustration of just how far a simple concept such as using gourds to suck bad blood out of people can come. Today, many industries worldwide would have a difficult time coping without some form of suction cup or vacuum pad to work with.
