US 5,019,056 A · Bowel care apparatus

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 drain line over a second predetermined time interval.

Dependent claims

Colonic lavage apparatus comprising:

a spectrum insertable into the rectum of a patient for lavaging the patient's colon and extracting waste matter therefrom;
a source of liquid under pressure including fill line means communicating with said speculum for delivering liquid under pressure through said speculum into the colon;
drain line means communicating with said speculum for drawing said liquid and extracted waste matter from the colon;
and
valve means interposed between said speculum and said drain line means including means communicating with said liquid pressure source whereby said valve means is directly responsive to the pressure of said liquid in said fill line means exceeding the pressure of said liquid in said speculum to move to a closed position in order to prevent the flow of said liquid therethrough and is directly responsive to the pressure of said liquid in said speculum exceeding the pressure of said liquid in said fill line means to move to an open position for draining said liquid and extracted waste matter from the colon of the patient.

Colonic lavage apparatus comprising:

a speculum insertable into the rectum of a patient for lavaging the patient's colon and extracting waste matter therefrom;
water fill line means communicating with said speculum for delivering water under pressure through said speculum into the colon;
pump means associated with said water fill line means for pumping water under pressure through said speculum into the colon;
drain line means communicating with said speculum for draining said water and extracted waste matter from the colon;
valve means connected in end-to-end relation between said speculum and said drain line means including means communicating with said liquid pressure source whereby said valve means is directly responsive to the pressure of said water in said fill line means exceeding the pressure of said water in said speculum to move to a closed position in order to prevent the flow of said water therethrough and is directly responsive to the pressure of said water in said speculum exceeding the pressure of said water in said fill line means to move to an open position for draining said water and extracted waste matter from the colon of the patient;
and
adjustable timer means for sequentially activating and deactivating said pump means over predetermined time intervals whereby water is supplied under pressure via said water fill line means over a first predetermined time interval and the water and waste matter are removed via said drain line over a second predetermined time interval.
