  • Patent number: 9017717
    Abstract: A bandage includes a reservoir filled with a perfluorochemical fluid, saturated with oxygen. Oxygen passes through a permeable membrane to the skin or wound to promote healing, and carbon dioxide travels from the skin or wound to the reservoir.

  • Patent number: 5741248
    Abstract: A method for cryogenic treatment of a lesion which includes the steps of delivering a fluorochemical liquid to the lesion, placing at least one cryoprobe into the lesion, and circulating cryogenic fluid through the cryoprobe, the cryogenic fluid causing an ice ball to form in a vicinity around the cryoprobe, wherein the ice ball obliterates at least a portion of the lesion. The fluorochemical liquid is utilized to augment the cryosurgical procedure and is perfused or injected into and/or around the lesioned site prior and/or during the application of a cryoprobe to the site. In one embodiment of the invention, the fluorochemical liquid acts as a contrast agent to enhance real-time medical imaging of the lesioned area and modifies the environment in and around the lesioned area. In another embodiment of the invention, the fluorochemical liquid augments cryosurgical procedures by controlling the size and shape of ice balls formed during the cryosurgical procedures.

  • Patent number: 4163639
    Abstract: A snowball maker has opposed inner and outer cup-like shells which interfit to compact snow into a ball. The inner shell deforms, within outer shell, upon full insertion substantially to encircle the snow within the two shells. Upon separating the shells, the inner shell resiliently opens to its original shape for ready release of the compacted ball of snow.

  • Patent number: 4062075
    Abstract: A bed having a torque-compensated parallelogram lifting arm arrangement. The bed has a subframe vertically adjustable by the parallelogram lifting arm arrangement and thereby retains a level relationship at all height adjustment levels.An articulated mattress support surface is provided, which is formed by articulated pivotally interconnected head or back, seat, thigh and leg sections mounted on the level vertically adjustable subframe. The seat section is double-pivoted, and enables simple and effective Trendelenburg and Reverse Trendelenburg positioning independent of any position of the height-adjustable supporting subframe. The seat, thigh, and head sections are articulated by cam and cam follower drive arrangements. Selective pivot defeat means are provided to enable selective pivotal lowering of the thigh and head or back sections without pivoting the seat section, and independent of the supporting subframe position, enabling simple and effective hyperextension positioning.
