A sampling apparatus for sampling body fluid includes a sampler having an external geometry selected to mate with an internal geometry of a testing apparatus such that the sampler may be inserted within the testing apparatus in a predetermined alignment&#x2014;and with a sampling location positioned accurately within a light path for detecting an amount of a desired constituent within fluid collected by the sampler.

A sampling apparatus for interstitial fluid includes a pressure ring surrounding a collection needle. The pressure ring and needle are movable relative to one another for the ring to first engage a patient's skin surface prior to insertion of the needle.

An asymmetrical, microporous, hollow fiber membrane is made from a polymeric dope mixture of polysulfone and polyvinyl pyrrolidone dissolved in an aprotic solvent. The physical morphology of the hollow fiber membrane, i.e., the asymmetric microporous wall, is rapidly formed by passing the polymeric dope mixture through an outer annular orifice of a tube-in-orifice spinneret while simultaneously passing a precipitating solution through the central tube of the spinneret. The emerging hollow fiber travels substantially downward for about 0.01-10 m before submersion into a quenching bath. The asymmetrical, microporous, hollow fiber membrane is biocompatible and suitable for use in, for example, dialysis, hemodialysis, ultrafiltration, and water filtration applications.

Hollow fiber membranes and method of manufacture

A low prime, high heat exchange efficiency oxygenator is provided which includes an oxygenation portion and a heat exchanger portion. Disposed within the heat exchanger portion is a hollow tube heat exchanger wound bundle which includes a plurality of hollow tubes knitted into a mat, the mat wound under tension into a bundle which includes from 16 to 24 layers of the mat. The oxygenator provided permits prime volumes of 180 to 240 mLs.

Interstitial fluid sampler

A unique hollow fiber filter cartridge that allows repeated autoclaving without any deleterious breaks in sealing integrity between the potted fiber bundle and the filter module is disclosed. The unique filter cartridge braodly includes a casing that has at least one open end with an inner lip in the casing proximal to the open end; and a porous collar that has first and second peripheral edges, at least one of which is coupled to the casing along the inner ledge.
