| 20090133853 | Thermal Transfer Device with Restriction-Resistant Tubing - An apparatus for selectively heating and cooling a body via a garment and attached heat transfer tubing. Operation of the garment is unaffected by external loads applied to the garment, such as backpack straps or harnesses. The garment includes restriction-resistant heat transfer tubing. The tubing is made of flexible, resilient material and has a lumen through which temperature-controlled fluid flows. In one embodiment, the lumen includes three internal protrusions or ribs extending radially from the inner wall and rounded at the tip. When an external load is applied to the tubing the internal ribs prevent complete closure of the lumen because the ribs provide support that separates the opposite sides of the tubing. The ribs, therefore, resist restriction of the flow of the heat transfer fluid. In various embodiments, the tubing and ribs take on different shapes while maintaining an open lumen through which temperature-controlled fluid may flow. | 05-28-2009 |
| 20090218812 | Safety Release Adapter - A safety release adapter for making a sealed fluid connection with a male connector that is disconnected when a pulling force is applied between the adapter and the connector. The safety release adapter includes a base and a socket. The base receives and secures a first male connector. The socket includes a cavity with a lip at the distal end of the socket. The socket releasably secures a second male connector with the lip inside the socket opening engaging a neck of the second male connector. The first male connector extends into the socket in a sealed interface with the socket such that when the second male connector is secured in the socket with a sealed interface with the socket, the valve buttons of each connector are mutually depressed so the two connectors are in sealed fluid communication. | 09-03-2009 |
| 20090264969 | Multi-mode cooling garment - Apparatus for cooling a person in extreme environments. The apparatus includes a garment having a vest with attached tubing. The vest includes an evaporative cooling device and the tubing is configured to circulate chilled water. The vest includes a material that is able to receive and absorb an amount of liquid water with a mass greater than the material. When liquid water is applied to the vest, the vest absorbs the water for later evaporation. The tubing enables the garment to have a lower differential temperature between the inside surface and the outside surface, thereby reducing the rate of evaporation, which enables the passive cooling to be operable for an extended period of time. When the heat load does not permit the differential temperature to be reduced, the tubing removes additional heat, thereby providing additional heat removing capacity beyond the passive cooling. | 10-22-2009 |
| 20100106229 | Thermal skull pads for coolant system - A bonnet-shaped pad configured to fit a skull is formed from a rectangular thermal pad. A rectangular pad has creases that allow the pad to conform to the shape of a human skull. The pad defines a cavity. The pad proximate the cavity includes a serpentine conduit configured to allow conditioned fluid to flow from an inlet to an outlet. The pad is configured such that fluid flow is not unduly restricted proximate the creases in the pad, thereby allowing the fluid to flow through the portion of the pad configured to be proximate the skull. The pad is connected to a cool water supply that pumps wool water through the pad at preselected intervals. In one configuration a remote, tethered switching unit controls the duty cycle of the pump, enabling cool water to flow through the pad after a selected time. | 04-29-2010 |
| 20110042942 | Pull release connectors - An apparatus for connecting two devices with a quick disconnect feature. A male plug is insertable into a female receiver and latched into position with a latch. The male plug is disconnected from the receiver by pulling the male plug out of the receiver with a force greater than an operating force. The male plug has a groove that engages a latch in the female receiver. The interface of the groove and the latch includes a bevel engaging a corner joining a surface perpendicular to a longitudinal axis and a surface parallel to the longitudinal axis. | 02-24-2011 |
| 20110192115 | Packaging system for a sterilizable item - Apparatus and a method for using a packaging system for a sterilizable item. The packaging system includes a first sleeve that is elongated and a second sleeve that encloses one end of the first sleeve. The first sleeve is an elongated open ended tube or pouch. The second sleeve is an open ended tube or pocket. The sides of the first sleeve and the sides of the second sleeve are proximate each other with the closed end of the first sleeve proximate a closed end of the second sleeve. The open end of the first sleeve is folded into a cuff that covers the open end of the second sleeve. In one embodiment, the apparatus includes a sterilization indicator affixed to the outside of the packaging system. | 08-11-2011 |
| 20120020182 | Sterile drape and agitator for slush solution - A method of fusing a sterile drape and an agitator together for containing a slush solution in a medical device. 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, the drape is a polyurethane material and the agitator is a polycarbonate material. | 01-26-2012 |
