  • PATHOLOGY SLIDE AUTOMATION SYSTEM AND METHOD
    Publication number: 20240085442
    Abstract: A slide carrier includes: a base support; and a slide platform having a surface that is parallel to a first plane defined by a first vector and a second vector, wherein a vector extending in a direction opposite to the direction of gravity is normal with respect to a second plane defined by a third vector and a fourth vector, an angle between the first vector and the third vector is greater than zero degrees and less than 90 degrees, and an angle between the second vector and the fourth vector is greater than zero degrees and less than 90 degrees.
    Type: Application
    Filed: August 17, 2023

  • Plasma separation card
    Patent number: 11353382
    Abstract: A multi-layer plasma separation card comprising (a) a first layer including a sample receiving member comprising (i) a top planar surface for applying or receiving a blood sample, said sample receiving portion being adapted to permit contact of said blood sample with a separating member; and (ii) a bottom planar surface being adapted to contact said separating member, (b) a second layer including at least three separating members, each separating member being adapted to permit the passage of plasma to an absorptive member and comprising (i) a top planar surface for receiving said blood sample; and (ii) a bottom planar shield-shaped surface being adapted to contact said absorptive member, and (c) a third layer including at least two absorptive members for absorbing plasma from the bottom planar surface of each corresponding separating member and a backing member arranged in a manner to support said absorptive members, each absorptive member comprising a removable absorptive element having a top planar surface
    Type: Grant
