A speculum assembly includes a tubular shaped housing having a first open end, a second end open and a peripheral wall extending between the first and second ends. A tubular shaped bladder has an open forward end, an open rear end and a perimeter wall extending between the forward and rear ends. The rear end is attached to and is coextensive with the second end so that the bladder extends forward of the second end of the housing. The bladder is inflatable and flares outwardly from the rear end to the forward end when the bladder is inflate. A pump apparatus is fluidly coupled to the bladder. The pump apparatus is adapted for inflating the bladder so that the bladder extends outwardly away from the housing. A sleeve is mounted to the housing and covers the bladder when the bladder is deflated. |
