Abstract: A system for detecting leaks in mattresses. The system allows for the detection of small holes in a mattress by applying pressurized gas or fluid to the mattress and observing the escape of gas or fluid through tears and incisions in the mattress cover in the formation of bubbles in a layer of solution covering the mattress cover. In an alternate embodiment, the escape of gas or fluid through the small holes produces ultrasonic vibrations, which an ultrasonic listening device detects, allowing an operator to determine the location of the holes.

Abstract: This invention involves a new and unique inflatable bathtub for bedridden patients. More particularly, the bathtub includes a thin pliable sheet such as vinyl, which may be disposed of after one or more uses. The pliable sheet has a multiplicity of the first portion of attaching members located around the peripheral of the pliable sheet. In a preferred embodiment, these first portions of the attaching members are simply apertures around the peripheral of the pliable sheet. The pliable sheet is placed under the patient in the well-known manner of changing bed sheets while the patient remains in the bed. An inflatable rim member made of heavy-duty material and having the cooperating second portion of the attaching members is then placed around the patient. The second portion of the attaching members may simply be hooks which cooperate with the multiplicity of apertures.
