    摘要： A fluid vessel insertion device (10), typically for medical use, comprises a puncture member (18) arranged for location within a sleeve (20), and a retraction mechanism (44, 48, 60) for retracting the puncture member relative to the sleeve. The puncture member (18) is retractable in use between a first condition in which an end (18A) of the puncture member protrudes beyond an end (24) of the sleeve and a second condition in which the end of the puncture member is within the sleeve (20). The retraction mechanism (44, 48, 60) actuates the puncture member between the first and second conditions in response to fluid pressure at the end (18A) of the puncture member. The device may be used during positioning of the sleeve in a desired fluid vessel, such as, for example, during intravenous cannulation.

    摘要： A hollow fiber microfiltration (MF) membrane is provided. The casting solution used to make this membrane includes a fiber-forming polymer having a degree of polymerization greater than about 1000, a water-soluble polymer, an anhydride with about 2 to 12 carbon atoms, and a solvent. The membrane is formed by mixing and heating these components to form a viscous dope and then extruding the dope through an annular orifice to form a hollow fiber MF membrane. The hollow fiber membrane is then fed through a coagulation bath and two leaching baths. The membrane is especially useful for filtering liquids, such as wine and juice, so as to remove bacteria, gel, and solid particles from the liquids.
