Abstract: A sealed bag for containing liquids. Typically made by a blowmolding process from a tube of molten thermoplastic resin. The bag comprises a tubular body of flexible plastic, sealed at one end, and narrowing to an integral tubular neck portion at the other end. A head portion, integral with the neck portion, seals the bag. A tubular recess is formed, typically in the head portion of the bag, for receiving a needle or the like for puncturing the bag to obtain the liquid contents. Generally, the cross section of the bag is oval, and a hanger at one end of the bag is attached thereto at a single station to facilitate collapse of the bag as liquid is withdrawn.

Abstract: A rotary seal for a centrifuge particularly usable in the process of cell washing for transferring fluid between a rotary member and a stationary member of an apparatus adapted to contain fluids. The rotary seal member comprises a hollow first housing, and a second housing disposed in the first housing in spaced relation therewith to define an annular chamber. One of the housings is rotatable in concentric relation relative to the other housing. A plurality of sealing means are transversely mounted between the first and second housings to divide the annular chamber into several separate sealed portions, and conduits lead from the exterior of both the first and second housings to separate sealed portions of the annular chamber.

Abstract: A catheter emplacement set comprises a hollow needle which carries a pair of cooperating, gripping flanges in pinching relation. A flexible cover is held in position relative the needle by the gripping flanges. A flexible catheter is slidably mounted in the bore of the needle, and the distal end of the catheter carries means for attaching it to a source of parenteral administration fluid. The needle is breakable into separate pieces for removal from the catheter upon manual pulling apart of the gripping flanges. A lanyard is attached to the distal end of the catheter and passes out of the cover adjacent the needle to facilitate rapid and smooth advancement of the catheter through the needle after emplacement of the needle in a blood vessel or the like.

Abstract translation: 导管插入组件包括中空针，其以夹持关系承载一对协作的夹紧凸缘。 柔性盖通过夹紧凸缘保持在针上。 柔性导管可滑动地安装在针的孔中，并且导管的远端携带用于将其附接到肠胃外给药流体源的装置。 当手动拉动夹紧凸缘时，该针可破碎成分开的部件以从导管中移除。 挂绳连接到导管的远端，并且在靠近针的位置上离开盖子，以便在将针放置在血管等中之后使导管快速平稳地前进穿过针头。
