Patent number: 11831705Abstract: A system, method, and apparatus for transferring blood donation files are disclosed. An example system includes a collection device located at a blood donation site and a collection server located in a remote location. The example collection device is configured to store blood donation information from blood donors within a blood donation batch file located at a designated directory of a memory, and store metadata related to the blood donation information to the blood donation batch file. The example collection device also transmits the blood donation batch file to a registered user device. The example collection server is configured to determine the registered user device is available via a network connection. Responsive to determining the user device is connected, the collection server acquires the blood donation batch file from the user device and aggregates the blood donation batch file with blood donation batch files received from other registered user devices.Type: GrantFiled: July 11, 2022Date of Patent: November 28, 2023Assignee: New York Blood Center, Inc.Inventor: Sabyasachi Sarkar
