A method for using an automated blood collection system to collect blood components from a subject includes separating plasma from whole blood as received from the subject; initiating an alert when a predicted accumulated volume loss is greater than a configured removal level, the predicted accumulated volume loss depending on an accumulated volume that includes the separated volume of plasma and the configured removal level being defined by a hypovolemic level or the pre-selected maximum for the subject; and in response to the alert and feedback from an operator of the automated blood collection system, ending the collection process, continuing the collection, or initiating platelet and red blood cell separation.

A blood collection tube holder having a retractable single needle and a body comprising substantially parallel and laterally spaced apart barrel and needle retraction cavities separated by a partial wall that facilitates lateral movement of the single needle from the barrel cavity into alignment with the needle retraction cavity to initiate needle retraction. The barrel and a frontal attachment to the barrel are cooperatively configured to facilitate relative sliding movement between in a direction that is transverse to the longitudinal axis through the retractable single needle to initiate needle retraction.

A device for communicating a driving ability level of a user, the device comprising at least a processor, a memory, and a wireless transceiver. The device is configured to: receive a communication from a medical device, wherein the communication comprises information relating to a condition of the medical device; and send a communication to a vehicle. The information relating to a condition of the medical device is processed in order to determine a driving ability level of the user by the assignment of a category selected from a group comprising a first category and a second category.
