Abstract: A tufted air mattress including a first printed sheet and a second sheet. The first printed sheet is printed over a selected area with an ink containing a fluoropolymer. The portion of the printed sheet with the ink defines a coated area. The first printed sheet attached to the second sheet where the printed sheet is not coated with the ink. The coated area of the printed sheet inhibits heat welding of the first sheet to the second sheet. The coated area also lubricates the first and second sheets to aid in inflating the air mattress without flaking and contaminating the air inflating the air mattress. In one embodiment of such a mattress, three sheets define two air volumes that are alternatingly inflated and deflated through an alternating air supply valve.

Abstract: A portable cooling system providing a controlled rate of cooling. The system includes a cool water device, a remote switching unit, and a thermal pad. The cool water device includes a coolant storage chamber separated from a pumping chamber by a baffle. The pumping chamber includes a pump and a discharge line with a flow restrictor for the fluid being returned from the thermal pad. In one embodiment, the remote switching unit actuates the portable cooling system and includes a timer feature for shutting down the system after a predetermined time. In another embodiment, the switching unit actuates a controller that sends a pulse stream to the pump to control the cooling water flow rate. The thermal pad includes fluid conduits that distribute the cooling water over the surface of the pad. In various embodiments, the thermal pad is a flat pad, a bonnet-shaped pad, and a cap-shaped pad.

Abstract: A sterile drape and agitator fused together, without an adhesive or solvent, for making surgical slush and an apparatus for manufacturing such a combination. A die, at a specified temperature, is forced against a drape and an agitator with a specified force for a specified time to form a fused area that has a shear strength that is not substantially reduced from the tensile strength of the drape itself. Additionally, the drape adjacent the fused area is not substantially weakened by the fusing of the drape to the agitator. In one embodiment, a machine for fusing the drape and agitator together is disclosed, the machine having a cylinder with a piston for forcing a die against the drape and the agitator, which is mounted on a fixed base.

Abstract: A therapy device for providing heated air to the upper body of a patient and a method of making and using the therapy device have been provided. The therapy device is an inflatable tube mounted on a base sheet and having a cover sheet. The patient is placed on the base sheet with the patient's head located between the legs of the tube. The cover sheet is placed over the patient's face. A heated air supply tube is connected to the tube and the heated air inflates the tube and heated air is forced out of the exhaust ports of the tube, thereby providing an environment in which a portion of the patient's body is heated. One method of fabricating the therapy device includes forming the individual pieces, attaching the tube sheets to form a tube, lancing the tube to form exhaust ports, and attaching the remaining pieces.

Abstract: An apparatus for pneumatic therapy blanket with sterile access. In one embodiment, an inflatable therapy blanket, which is sterilized, has an opening in the patient's chest area. In another embodiment, a perforated seam is positioned along the longitudinal axis of the blanket between the patient's neck and the access opening. By breaking the perforation, a slit is formed, allowing access to the patient's body from outside the blanket. In another embodiment, the blanket covers only the lower portion of the patient's body and the blanket has a tape edge for attaching the blanket to the patient's body.

Abstract: A therapy device for providing heated air to the body of a patient through a plurality of V-shaped slits. The therapy device is an inflatable tube. A heated air supply is connected to the tube and the heated air inflates the tube and is forced out of the exhaust ports. The exhaust ports are V-shaped slits. The method of fabricating the therapy device includes forming the individual pieces, attaching the tube sheets to form a tube, lancing the tube to form exhaust ports, and attaching the remaining pieces.

Abstract: A package for a sterilizable item is provided. The package includes a tubular member having an open end and a closed end. A reinforcing panel encompassing the closed end is secured to the tubular member proximate the closed end such that the reinforcing panel includes an open end. A cuff portion is attached to the tubular member proximate the open end of the tubular member. The cuff portion includes a first edge secured to the tubular member and a second edge in spaced relation from the first edge, wherein in the cuff portion extends from the open end of the tubular member and substantially overlaps the open end of said reinforcing panel. A portion of the inside surface of the tubular member is thus exposed and defines the width of the cuff portion. In the preferred embodiment, the cuff portion is integral with the tubular member.

Abstract: A disposable applicator has a frangible housing which prior to rupture can effectively maintain a sterile field for storage of antiseptic or the like. Preselected fluid matter is impregnated in an absorbent pad received within the frangible housing. During use, the housing is initially ruptured by peeling away a sealing layer from a supporting member so as to expose the absorbent pad. Then, upright members extending from the housing may be squeezed together for purposes of both handling the applicator and for flexing the remaining housing portion so as to push the absorbent pad away from the housing and towards the target surface. The absorbent pad is received within a concavity of the housing, which concavity tends to be flattened out by squeezing together the upright members which extend from the housing.

Abstract: A disposable or reusable "crawl resistant" flexible mattress formed of panels sealed together to define alternately inflatable passages between the panels for sequentially supporting structure for a long term bed patient to reduce decubitus ulcers, bed sores, etc. The mattress has vent holes in its top for ventilating the patient with inflation gas and a crawl resistant layer bonded to a bottom of the mattress to prevent the mattress from "crawling" relative to the bed and patient during use. In one form of the mattress, crawling is reduced by a separation between the inflation passages so individual sections of the mattress can more readily conform to a patient's body contour.

Abstract: A flexible pad with interconnecting internal passages for circulating a hot or cold liquid for treating a patient. The pad has an improved internal flow pattern that includes a set of partitions that separate the pad into a plurality of major fields that are connected in series to insure that liquid flows to all areas, i.e. fields, of the pad even when such pad is in folded condition. Within each field is a series of passages forming a crisscross waffle grid pattern for random liquid flow in many directions within each field to reduce the chance of blocking liquid circulation through the pad when it is in folded condition.
