Abstract

A characteristic of a blood product in a blood product container is determined. Using a smartphone, an image is acquired of a blood bag or tubing of the blood product container disposed in front of the smartphone. The image is processed using a processing circuit of the smartphone or a remote computer in wireless communication with the smartphone. The processing identifies a characteristic of the blood product from the image. A visual notification is generated on a display of the smartphone of the identified characteristic of the blood product.

First claim

What is claimed is:

1. A method of determining a condition of a blood component that has been separated from whole blood and collected in a blood product container, comprising:
acquiring an image of the blood product container using a camera of a handheld computing device;
processing the image to determine the condition of the blood component within the blood product container; and
generating a visual notification of the determined condition on a display of the handheld computing device, wherein a color tag having a predetermined color is attached to the blood product container, wherein the acquiring further comprises acquiring an image of the color tag, wherein the processing further comprises identifying the color tag and calibrating an image processing algorithm using the color of the color tag.

2. The method of claim 1 , wherein the color tag comprises a plurality of colors and the calibrating further comprises creating a calibration curve based on image values acquired from the image of the color tag.

3. The method of claim 1 , wherein the handheld computing device is a smartphone and the blood component that has been separated from whole blood is plasma and/or platelets.

4. The method of claim 1 , further comprising scanning a barcode on the blood product container to generate a container identifier, wherein the container identifier is stored in association with the identified condition in a memory of the handheld computing device, further comprising communicating the container identifier and identified condition over a network to a remote computer, wherein the remote computer is part of a blood establishment computer database.

5. The method of claim 1 , further comprising communicating the identified condition wirelessly to a memory tag attached to the blood product container, wherein the memory tag comprises a radio frequency identification tag.

6. A handheld computing device programmed to identify a condition of a blood component separated from whole blood and disposed in a blood product container, comprising:
a portable housing configured to be held in a hand of a user during use;
a network interface circuit configured to communicate wirelessly with a network;
a display;
a camera; and
a processing circuit configured to:
use the camera to scan a code on the blood product container;
store an identifier in memory based on the scanned code;
use the camera to acquire an image of the blood product container;
determine a condition of the blood component within the blood product container based on the acquired image, wherein the processing circuit performs image processing or sends the image over the network to a remote computer for image processing, wherein a color tag having a predetermined color is attached to the blood product container, wherein the processing circuit is configured to acquire an image of the color tag, wherein the processing circuit is configured to identify the color tag and calibrate an image processing algorithm using the color of the color tag; and
generate a notification on the display indicative of the determined condition.

7. The handheld computing device of claim 6 , wherein the processing circuit is further configured to:
download an application over the network from an application database comprising a plurality of different applications;
display an icon associated with the application on a home screen comprising icons for other applications;
receive a selection of the icon associated with the application to open the application, wherein the application programs the processing circuit to acquire the image of the blood product container, determine the condition of the blood component within the blood product container, and generate the notification on the display indicative of the determined condition.

8. The handheld computing device of claim 6 , wherein the processing circuit is further configured to communicate the identifier and determined condition over a network to a remote computer, wherein the remote computer is part of a blood center database.

9. The handheld computing device of claim 6 , wherein the processing circuit is further configured to communicate the determined condition wirelessly to a memory tag attached to the blood product container, wherein the memory tag comprises a radio frequency identification tag.
