Patent number: 5588167Abstract: An apparatus and method for managing waste from patient care, maintenance, and/or treatment includes an inflatable bladder member disposed to support at least a first portion of the body of the patient. A flexible basin member is fitted over the bladder and receives waste materials, and a filter sheet is disposed atop the basin member. The basin member is connected to a liquid/gas separator and a vacuum blower. A liquid waste pump is connected to the separator to transfer liquid waste to a holding jug. A vacuum wand provides both suction and rinsing liquid via an on-demand pumping supply configuration that enables the rinsing liquid supplied from a rinse jug to be heated. Liquid levels in the rinse liquid jug, the holding jug, and the separator's holding reservoir are sensed by capacitive level sensing devices which supply signals to a microprocessor which controls various functions of the apparatus. Special inflatable sacks are provided to assist turning the patient to facilitate cleansing of the patient.Type: GrantFiled: May 11, 1995Date of Patent: December 31, 1996Assignee: SSI Medical Services, Inc.Inventors: Demetrios A.

Patent number: 5355537Abstract: An environmentally controlled portable toilet designed to neutralize and confine contaminating agents such as bacteria, odors, vapors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the bowl-structure. A circular shaped bowl-structure (170) with a circular air-trapping cavity created inside the bowl-structure (170) by a seat-skirt (188), confines the contaminating agents during toilet use and improves the efficiency of the air circulation. A removable air-cooling tray 134, and sanitizer and odor conditioner cartridges (131) are employed to cool the air moving inside the air-trapping cavity, and respectively, to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (170). A toilet seat (182) having an ergonomic design has a seat-skirt (188). The invention is applicable to portable toilet systems including children's training toilets.Type: GrantFiled: May 10, 1993Date of Patent: October 18, 1994Inventor: Daniel S. Redford

Patent number: 4942632Abstract: A method and apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect fecal matter, scrub the waste collector area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation.Type: GrantFiled: August 10, 1989Date of Patent: July 24, 1990Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: William E.
