Abstract: A bed for patient care having a waste disposal system. The bed includes a back, seat and two leg sections for supporting the patient. These sections of the bed may be raised and lowered and tilted. The leg sections may be moved independently for use with patients having one leg immobilized. The seat section includes two panels which part to permit a waste canister to be raised to interface with the buttocks of the patient. An audible signal alerts the patient prior to this action. The waste canister provides a directable bidet wash, and an air drying feature. Gelling material within the canister swells during the bidet function to cover and seal the waste. The entire canister may be sealed and disposed of.

Abstract: A safety pad or mattress such as for use in a crib prevents sudden infant death syndrome by ensuring an oxygenated breathing space for the infant. Reticulated foam is made into a pad or a mattress and may be covered with a fitted open weave fabric covering. An embedded air tube is interconnected with an air pump which circulates fresh, i.e., oxygenated, air in the breathing space. The air pump may be inside or outside the mattress. The forced air circulation flushes any exhaled carbon dioxide from the breathing space, even when the infant is face down or otherwise in a prone position on the mattress, to prevent carbon dioxide poisoning. The air circulation flow rate is limited to prevent infant cooling. A pad bladder for similar function may be provided having a layer of reticulated foam sandwiched between upper and lower air impervious sheets and dispersing air introduced therebetween. The upper sheet has a pattern of air holes for release of the dispersed air.

Abstract: A pressure relief support system utilizes a self-adjusting approach to maintaining generally constant pressure in fluid support bladders. A constant force, such as from a constant force linear spring or from a counterweight system, is applied directly to a fluid support bladder or to a reservoir in fluid communication with such bladder. Plural self-adjusting arrangements may be provided in a single device for fabricating a support body with sectionalized support. Such arrangements may be incorporated into mattress support systems or into seating arrangements or other alternative uses. By appropriately selecting system components, such as the amount of the constant force applied, the original volume of fluid to which the force is applied, and the reservoir size, pressure dispersion for a patient or supported object of any type may be controlled at a predetermined generally constant point.

Abstract: A marine craft fuel alert system is operative during a given time period, to compare actual fuel capacity measurements with selected fuel tank capacity reference values, to permit timely intervention. Used with a relatively high reference value and operative during fuel loading, the system and methodology gives a warning to a fuel input agent (i.e., person controlling fuel loading) in sufficient time for the agent to terminate fuel loading and prevent environmental pollution by fuel overfill spillage. Conversely, the system and methodology, with appropriate modifications, can be used to sense and warn of predetermined low fuel level conditions. The system can be integrally incorporated into an original equipment marine craft system or retrofit thereto. Electrical interconnections may extend to marine craft ignition system interdiction during operation of the fuel loading monitoring and warning.

Abstract: A safety pad or mattress such as for use in a crib prevents sudden infant death syndrome by ensuring an oxygenated breathing space beneath the infant. Reticulated foam or other air permeable material is made into the shape of a pad or even a mattress and covered with a fitted open weave fabric covering. An air tube is embedded in the pad or mattress and interconnected with an air pump which circulates fresh, i.e., oxygenated, air in a breathing space formed beneath an infant by the air permeable mattress. The forced air circulation flushes any exhaled carbon dioxide from the breathing space, even when the infant is face down or otherwise in a prone position on the mattress, to prevent carbon dioxide poisoning. The materials of the fabric covering and air permeable mattress permit any fluids regurgitated from the infant to drain away from the infant's face.

Abstract: Method and apparatus for treating a patient by electrotherapy and fluidized bed thermal therapy. A body portion of a patient is submerged in a fluidizable bed of solid particles, and the bed is selectively fluidized and de-fluidized as desired while controlling the temperature of the bed of solid particles. Electrotherapy treatment is applied to the portion of the body of the patient submerged in the bed of solid particles through electrodes attached to the body part which are connected to an electrical generator which produces radio frequency signals in continuous or modulated modes. The electrotherapy and fluidized bed thermal therapy may be applied consecutively or concurrently to the body part for treatment thereof.

Abstract: A collection, storage and disposal system for human wastes. An externally positionable patient interface directs wastes through a conduit to a storage container. Accumulated wastes are sealed within the storage container to prevent cross-contamination. The patient interface is extendable through an aperture formed within a seat portion of a support structure which can be converted between bed and chair configurations. A mattress has a foam insert which may be selectively inflated to maintain desired supporting pressure for the patient and to provide a resilient support surface should deflation of the mattress occur.

Abstract: An oil and water separator for separating oil from water collected in a bilge of a boat prior to discharging the water overboard. A reservoir is provided for receiving the mixture of oil and water from the bilge. The oil separates from the water and floats on top of the water. When only water is positioned between a pair of spaced electrical probes carried in the reservoir, such causes a drain valve to be opened to drain the water from the reservoir. As the water is drained from the reservoir, the oil floating on top of the water will come between the probes and close the valve, stopping the draining of water from the bottom of the reservoir. A mixture of oil and water is pumped from a tank carried in the bilge at an intermittent rate so that the mixture is allowed sufficient time to separate in the reservoir.

Abstract: A marine craft includes a pollution control device for marine fuel tanks. The pollution control device includes a compartment for receiving fuel that leaves the fuel tank headed toward the vent via the vent line. The volume of the compartment desirably holds more fuel than would be contained in the volume of the length of the vent line that extends from the fuel tank to the vent. The compartment has an inlet that communicates with the fuel tank via the vent line. The compartment has an outlet that communicates with the vent via the vent line. The device includes a guide tube disposed within the compartment for preventing direct transmission of fuel to the vent. The device includes a float member disposed within the guide tube for detecting fuel in the vent line. The device includes an alarm circuit activated when the float member is located at a predetermined position within the guide tube.

Abstract: A patient's head, chest and upper torso are supported on a first surface formed by a plurality of inflatable sacks disposed on an articulatable member. The patient's lower torso, buttocks, legs and feet are supported on a second surface formed by air fluidizing a mass of fluidizable material. A blower inflates the sacks and the fluidizable material via a network including manifolds, valves, and flexible tubing. A microprocessor controls actuation of the articulatable member, the various valves, and the blower, according to signals inputted by operating personnel or supplied by various monitoring sensors. The flow of air to the fluidizable material beneath the buttocks of the patient is reduced when the articulatable member is raised, thus increasing the density of support beneath the patient's buttocks and counteracting the tendency of the shifting weight of the patient's upper body to slide the patient toward the foot of the bed.
