DETECTING SCAN AREA WITHIN HEMATOLOGY SLIDES IN DIGITAL MICROSCOPY
20230377144 · 2023-11-23 · ·

A microscope system for detecting a scan area within hematology slides in digital microscopy may include a scanning apparatus to scan a hematology sample, and a processor coupled to the scanning apparatus and a memory. The processor may be configured to execute instructions which may cause the system to receive a first image of the sample at a first resolution and determine a scan area of the sample to scan in response to the first image. The instructions may further cause the system to scan the scan area to generate an image of the scan area at a second resolution greater than the first resolution and classify a plurality of cells from the image of the scan area into cell data comprising a plurality of cell parameters. The instructions may also cause the microscope system to output the cell data. Various other systems and methods are provided.

Blood indicator panel
11493501 · 2022-11-08 · ·

Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices include the use of a RBC flocculant, such as polyDADMAC, and an approximate blood hematocrit for the type of animal, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal type hematocrit, and a calculated RBC packing ratio “η” value for the collection device. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.

Method and apparatus for buffy coat imaging

A blood sample processor for imaging a centrifuged blood sample is provided including a transparent container with the centrifuged blood sample therein. An illumination source is positioned to illuminate the centrifuged blood sample at a non-right angle to the transparent container. A digital camera disposed opposite the transparent container images the centrifuged blood sample and the image is processed to determine the relative locations of component layers of the centrifuged blood sample.

Multiple laminar flow-based particle and cellular separation with laser steering

The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.
