Abstract:
The present invention provides an improved coextruded medical grade port tubing. The medical grade port tubing provides characteristics that are desirable in the medical industry and therefore can be used as a medical port tubing in, for example, renal therapy or blood donor tubes. To this end, the present invention provides a non-PVC coextruded medical grade port tubing including: an outer layer comprising a blend of polypropylene copolymer and styrene-ethylene-butylene-styrene copolymer; a tie layer; and a core layer including a blend of polyamide and ethylene vinyl acetate.
Abstract:
The apparatus described includes a fixed plate and a movable plate mounted to vibrate relative to the fixed plate in a plane parallel to the plane of the fixed plate. The plates are spaced apart so that fluid can be placed therebetween. A drive system maintains the movable plate vibrating at its resonant frequency. The drive system uses a sinusoidal drive with a linear transducer to facilitate determination of viscosity simply by measuring the peak driving force.
