ABSTRACT:
A colonic lavage apparatus including a speculum (12) in which the speculum (12) takes the form of an elongated tubular body (29) having a tapered leading end (30) provided with a pair of diametrically opposed apertures (36). The major length of the body (29) tapers rearwardly from the leading end (30) into a trailing end (45) which is coupled to a liquid delivery line (L) from a source of liquid under pressure. A control line (L') is coupled to a valve assembly (16) at an opposite end of the speculum (12) to that of the delivery line (L), the valve assembly (16) including an elastic tubular liner (28) and a pressure port (24) positioned on an external surface of the valve (16) which is in communication with the source of liquid under pressure, the valve (16) being opened and closed in response to the differential pressure between the liquid in the pressure port (24) and the speculum (12). The speculum (12) may be provided with an inflatable cuff (72) and means for inflating the cuff (72) in order to hold the speculum (12) in the anal canal of a patient.
