Bulb pump for impotence therapy and other purposes

A manually operated pump in combination with apparatus for aiding a male to obtain an erection, said apparatus comprising a chamber in which there is an opening having a rim for being pressed in releasable and sealable fashion against the body circumjacent the base of the penis while the penis is disposed in the chamber,

• said pump comprising a bulb having a wall composed of elastic material,
• a first protuberance composed of said elastic material projecting from said wall inwardly of the bulb and having an air intake passageway, said protuberance having an air intake slit for communicating the interior of the bulb with said air intake passageway,
• a second protuberance composed of said elastic material and having an air exhaust passageway, said second protuberance having an air exhaust slit for communicating the interior of the bulb with said exhaust passageway,
• squeezing said bulb to deform it causing air pressure to increase in said bulb for forcing said air exhaust slit to open and said air intake slit to close, and
• relieving said bulb after deforming it restoring said bulb to undeformed condition to create vacuum in said bulb that results in said air exhaust slit closing and said air intake slit opening for drawing air into said bulb,
• a connector on said chamber for connecting one end of a flexible tube to said chamber and a connector on said bulb for connecting the opposite end of said tube to said bulb in communication with said air intake passageway, such that said chamber becomes evacuated in response to alternatingly squeezing and relieving said bulb.
