摘要： A filter is disclosed having a layer of electret filter media or triboelectric filter media immediately adjacent or in intimate contact with one, or both sides, of a layer of hydrophobic media. Such filter is placed in communication with the upstream and/or downstream side of a mechanical electronic or electrostatic filter to solve problems present in the prior art. Additionally, a medical ventilator filter and system using such a filter is disclosed.

摘要： A combination filter/dehydrator is disclosed which first filters a stream of oil or fluid of low volatility to remove particulate contaminants, and then passes the stream through a dehydrator 38 to remove free, emulsified, or dissolved entrained water. A pressure control valve 46 is provided to enable a portion of the oil stream to bypass the dehydrator in order to maintain a predetermined pressure differential across the dehydrator membrane. A discharge chamber (FIG. 5) is provided at an outlet of the dehydrator to prevent the loss of oil that has permeated the dehydrator membrane. A sweep gas stream 70 for removing water from the permeate side of the dehydrator membrane can include a coalescer 72 (FIG. 4) for removing liquids entrained in the sweep gas before entering device.

摘要： A method and apparatus for the removal of free, emulsified, or dissolved water from liquids of low volatility, such as oil, is shown. The liquid of low volatility is removed by contacting the fluid stream of concern with one side of a semi-permeable membrane. The membrane divides a separation chamber into a feed side into which the stream of fluid is fed, and a permeate side from which the water is removed. The permeate side of the chamber is maintained at a low partial pressure of water through presence of vacuum, or by use of a sweep gas.

摘要： A membrane air drier utilizes an orifice to serve as the sweep air inlet with a sweep diffuser placed a short distance from the orifice. Preferably, an open channel extends from the product end of the membrane module on the shell side of the fibers with a porous diffuser at one end of the open channel and an orifice at the other end of the channel.

摘要： A method and means effectively evacuates smoke plumes, vapors, aerosol release, mists, tissue and small particles produced from an operative nasal cavity and any other gas- or air-borne materials provided in or produced in the surgical environment. To this end, an evacuator tube is placed in the contralateral (suction) nasal cavity surrounded by a sealing member which blocks the space between the evacuator tube and nares and/or nasal vestibule.

摘要： A method and apparatus deliver dry, flowable hemostatic powder into a gas flow stream by gravity delivery within a body of the apparatus. The hemostatic powder is then carried with the gas out of the apparatus into an elongated delivery tube inserted into a patient. Delivery of the powder into the gas flow stream creates a bolus of powder and air which becomes more uniformly distributed as it passes through the elongated delivery tube.

摘要： 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.
