摘要： A trocar containing a universal seal for sealing against surgical instruments of varying diameter to maintain insufflation in the body cavity is disclosed. The universal seal has an elastomeric sealing component with a centrally located interior region containing an aperture, and a concentrically located sealing region. The sealing region is composed of an integral laminate having an overlaying layer co-molded with an underlying layer. The overlaying layer has a hardness between about 40 Shore A Durometer Scale and about 80 Shore D Durometer Scale. The underlying layer has a hardness between about 5 Shore A Durometer Scale and about 40 Shore A Durometer Scale. The co-molded laminate balances the properties of tear resistance and elasticity which are necessary for a working universal seal, and does so without the need for resilient legs or protectors to facilitate the opening of the aperture of the seal or to prevent tearing when instruments are inserted.
摘要翻译：公开了一种套管针，其包含用于密封不同直径的外科器械的通用密封件，以维持体腔内的吹气。通用密封件具有弹性体密封部件，其具有位于中心的内部区域，该内部区域包含孔和同心位置的密封区域。密封区域由具有与下层共同模制的覆盖层的整体层压体组成。覆盖层具有在约40肖氏硬度计量度和约80肖氏硬度计量度之间的硬度。下层具有在约5肖氏硬度计量度和约40肖氏硬度计量度之间的硬度。共同成型的层压板平衡了工作通用密封件所必需的抗撕裂性和弹性的性质，并且不需要弹性腿或保护件来促进密封件的孔的打开，或者当仪器是插入。

摘要： A uniaxially oriented, polyolefin film is prepared by melt blending a mixture of a polyolefin, an inert filler, a processing aid such as calcium stearate, and optionally a stabilizer, maintaining the moisture level in the melt blend below 700 ppm, casting a film, and uniaxially stretching the film at least about 2 times its original casting dimensions in one direction until the film has a sufficient number of elongated, narrow shaped, microporous voids in order to create a CO.sub.2 and O.sub.2 permeance in the range of 5,000 to 10,000,000 cc/100.sup.2 -atm-day. Such a film is used in a controlled atmosphere packaging container as a panel in a window for a controlled flow or flux of CO.sub.2 and O.sub.2 through its wall in an otherwise gas impermeable container.

摘要： A container for storage of fruits or vegetables wherein the optimum environment, i.e., the optimum carbon dioxide to oxygen ratio, for the storage of said fruits or vegetable can be attained and maintained, thereby retarding maturation and spoilage thereof. The environment is controlled by providing a resin-coated nonwoven panel of limited carbon dioxide and oxygen permeability on an otherwise substantially impermeable container. The size of this panel is a function of its permeability, the amount and respiration rate of the contents, and the ratio of carbon dioxide of oxygen desired.

摘要： A container providing controlled atmospheric storage of produce (i.e., fresh fruits, vegetables and flowers) to improve retention of product freshness by adjusting the carbon dioxide to oxygen ratio, for the storage of said produce, can be attained and maintained, thereby retarding premature maturation and spoilage. The environment is controlled by providing a microporous membrane panel of a uniaxially or biaxially oriented microporous polyolefin coated with a cured silicone elastomer, said panel being of limited carbon dioxide and oxygen permeance on an otherwise substantially impermeable container. The size of the area of the panel is a function of its permeance, the amount and respiration rate of the contents, and the ratio of carbon dioxide to oxygen desired.

摘要： A soft, flexible, microporous film is provided having high tensile strength and good air and water vapor transmission rates therethrough while being substantially impenetrable to liquid water. This film is prepared by stretching a casting of a composition of a polyolefin and high levels of CaCO.sub.3 or glass beads and calcium stearate in two directions from 1.5-7 times in each direction to produce a film having a Gurley porosity of from 0.1 to 85 seconds. This film is especially useful for disposable items such as feminine panty liners, diapers, bed sheets, and hospital gowns. When glass beads are substituted for the CaCO.sub.3, the film is useful for battery separators.

摘要： A container capable of creating within it preselected CO.sub.2, O.sub.2, and moisture concentrations in the presence of respiring fresh fruit, vegetables, or flowers is constructed of a substantially gas-impermeable material having a gas-permeable panel that is substantially impermeable to moisture in one or more of its walls to provide a controlled flow of CO.sub.2 and O.sub.2 through its walls and a cellophane panel that is substantially impermeable to the flow of CO.sub.2 and O.sub.2 in one or more of its walls to provide a controlled flow of moisture through its walls. The gas-permeable panel is a uniaxially or biaxially oriented film where the size of the area it covers is a function of its permeance, the amount and respiration rate of the contents, and the desired steady-state oxygen concentration. The size of the cellophane panel is a function of its permeance to water vapor and the desired rate of removal of water vapor from the package.
