  • Patent number: 11964117
    Abstract: An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.

  • Patent number: 4001197
    Abstract: A magnetic separation method for recovering single cell protein from single cell organisms including dispersing magnetic seed in a fluid medium containing single cell organisms, to allow the attachment of the seed to the single cell organisms in the mixture to occur; submitting the resulting mixture to a magnetic separator to attract and hold by magnetic forces the seed and attached single cell organisms to concentrate the single cell organisms in the magnetic separator; lysing the entrapped single cell organisms to break the cell walls of the single cell organisms and release protein from the single cell organisms into the fluid medium; and recovering the released protein by discharging the fluid medium from the magnetic separator while the seed and remaining portions of the cells attached to the magnetic seed are held by the magnetic forces.
