  • ATP-dependent mechanics of red blood cells
    Red blood cells are amazingly deformable structures able to recover their initial shape even after large deformations as when passing through tight blood capillaries. The reason for this exceptional property is found in the composition of the membrane and the membrane-cytoskeleton interaction. We
  • Can a Fluid Sensor Make Kidney Dialysis Pleasant?
    hemodialysis. Hemodialysis uses external equipment that allows the patient's blood to be pumped through a medical device (dialysis machine) equipped with a hemodialysis membrane-the artificial kidney.
  • Medical Device Link .
    Described as an alternative to traditional peristaltic technology, a haemodialysis pump applies positive and negative pressure to a flexible membrane within each pumping chamber to achieve blood flow. Renal Solutions Inc. (Warrendale, PA, USA; ) initially fabricated the pump from a conventional

  • Medical Device Link . Design Solutions Using Microporous Hydrophobic Membranes
    ). Microporous hydrophobic membrane--shown in roll at top--is used in products such as (clockwise from left) a vented blood warmer, an in-line suction filter, a vented suction container, and a transducer protector.

  • Medical Device Link .
    glucose monitors. The key component of such monitors is a flat, membrane-covered unit called a planar sensor (see Figure 1). Over the past few years, planar sensors have been brought into use for measuring blood gases and electrolytes, and have also been introduced in portable cartridge-based
  • Prions Come Under Closer Scrutiny
    In plasma manufacturing, Martin says, charge-depth and viral filtration can be used to remove prions, as can membrane chromatography. However, viral filtration can only remove prions that have aggregated. Ion-exchange column chromatography can be used to remove individual prions, but the columns
  • Medical Device Link . Technology news
    A multifunction switch module that uses laminated glass in lieu of a plastic overlay remains transparent over time, is scratch resistant, and withstands exposure to aggressive fluids such as acids, dyes, and blood. In addition, the keyboard layout, labelling, and pin assignments can be configured
