Portable Blood Count Monitor
First Claim
1. A system for determining the number and type of blood cells in a sample, the system comprising:
- a slide for collecting and holding a blood sample of less than or equal to 5 uL, wherein the slide comprises a blood inlet and at least two sampling chambers; and
a slide analyzer for receiving and analyzing the slide, the slide analyzer comprising a light source configured to project light onto the slide, a slide receiver for receiving the slide, an optics assembly, an image receiver for capturing one or more images from the at least two sampling chambers, and an image analyzer for analyzing the captured images to determine the number and type of blood cells in the sample.

Abstract
Devices, systems, and methods are disclosed for determining the number and type of blood cells in a blood sample. The blood sample is collected and held in a slide. In the slide, the blood sample is separated and channeled into at least two sampling chambers, one for red blood cells, another for white blood cells, and optionally yet another for platelets. The sampling chambers have wetting agents, lysing agents, staining agents, or the like therein to mix with the blood and facilitate cell count. The slide is placed in a portable slide analyzer where the sampling chambers are illuminated and images of the sampling chambers are taken. These images are converted into electronic form and sent by a communications module of the slide analyzer to a remote external location where the images are analyzed to determine the number and type of blood cells in the blood sample.

22. A method for determining the number and type of blood cells in a sample, the method comprising:
-
collecting a blood sample of less than or equal to 5 uL through an inlet of a slide; channeling the blood sample into a first sampling chamber and a second sampling chamber; receiving the slide in a slide analyzer; acquiring an image of the first sampling chamber of the slide analyzer; acquiring an image of the second sampling chamber of the slide analyzer; analyzing the image of the first sampling chamber to determine at least one of the number and size of red blood cells in the blood sample; and analyzing the image of the second sampling chamber to determine the number or type of white blood cells in the blood sample. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
