  • Rectal insertion device and control valve means therefor
    Patent number: 5176630
    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).

  • Bowel care apparatus
    Patent number: 5019056
    Abstract: A bowel care system is made up of a wheeled cart unit so as to be readily transportable between a patient and bathroom for removal of waste matter from the patient by means of colonic lavage apparatus mounted on the unit, the apparatus including a fill container and waste reservoir with a fill line extending from the fill container into communication with a speculum which is insertable into the anal canal of the patient, a pump for pumping water under pressure through the speculum, a drain line also communicating with the speculum at a location downstream of the fill line with a valve between the speculum and drain line which is movable between open and closed positions in response to differential pressure between the pump and speculum, and a timer is provided for sequentially activating and deactivating the pump over predetermined time intervals so that water is supplied under pressure over a first predetermined time interval through the speculum followed by remobal of the water and waste matter via the drai
