  • Patent number: 8057670
    Abstract: A biological fluid processing or fluid filtration system is provided having novel open and closed loop processing systems wherein the gases transferred into and out of the system during processing pass through a porous medium in upstream and/or downstream gas inlet or outlet housings or vents in a manner which precludes the fluid being processed or filtered from ever contacting the housings or vents. Each housing or vent is separated from the fluid by a column of gas in its respective transfer line. The upstream gas inlet housing or vent is in communication with the unfiltered biological fluid, and the downstream gas inlet housing or vent is in communication with the filtered biological fluid.

  • Patent number: 7897038
    Abstract: A novel surface treatment is provided for portions of filter media coming in contact with the filter media holder, such as filter housing. In certain applications, the treatment is also applied to the filter media holder, depending on the application. Filter media having at least two distinct surface property modifications are provided in liquid filtration applications to enhance the performance of a filtration system, reduce the cost of the system, provided a visual means of detecting fluid bypass, and minimize fluid holdup volume within the filter media, all with substantially no loss of performance performances parameters, even in steam sterilization applications.

  • Publication number: 20100108592
    Abstract: An improved biological fluid filtration system is shown having, seriatim, a blood container, a biological fluid filtration device downstream of the blood container, and a blood receiving container downstream of the biological fluid filtration device; a bypass line is provided to allow fluid communication between the blood container and the blood receiving container, the bypass line includes a loop, the loop of the bypass line being configured to be disposed above the blood container at a sufficient height to prevent the passage of fluid around the leukocyte depletion device; the loop of the bypass line being disposed in a tube support device, the tube support device being configured to support substantially the entire weight of the biological fluid filtration system without substantially crimping said bypass line.

  • Publication number: 20090270837
    Abstract: An improved tubing device, preferably for use in the medical industry is provided. The tubing device provides a seamless transport path by using the tubing itself as the transport means without any other internally wetted parts, or connections, to provide a substantial reduction in the number of fluid contact components, and eliminate the need for cutting tubes into segments to be later bonded via tubing connectors. This can reduce the risk of contamination of the transported materials and can also reduce the use of chemicals such as adhesives and bonding agents.

  • Publication number: 20090226391
    Abstract: A method of making a wound dressing comprises dissolving at least one hemostatic agent in at least one solvent to form a solution. The method continues by freeze drying the solution to form a sponge. The method further comprises compressing the sponge, wherein the sponge is subjected to a vapor above ambient temperature prior to or during the compression.

  • Patent number: 7476212
    Abstract: An apparatus and method for on-the-go humidifying an insufflation gas through water vapor transfer from a liquid to the insufflation gas through a barrier separating the gas from the liquid to enable the gas in a normally trauma inducing state to be brought to a conditioned state. If the gas is at an improper insufflation temperature the temperature of the gas can be brought to the proper insufflation temperature at the same time the gas is humidified through heat transfer through the barrier.

  • Patent number: 7303605
    Abstract: A fluid filter is provided with a snap-together housing for the filter media. The housing is designed with two main parts that are easily snapped together to encapsulate the filter media. The filter housing is substantially cylindrical, and contains an inlet on one end of the filter and an outlet on the opposing end. The filter can be designed so as to be opened for the replacement of the filter media.
