Self-contained systems and methods for controlled dispensing of hazardous fluid

Abstract

The present technology is directed to extraction devices, systems, and methods for controllably withdrawing and transferring fluid samples, such as blood, from a sample collection container to a testing device. For example, some embodiments of the present technology provide fluid extraction devices that include a fluid control module, a housing containing a receiving element and a suction element, and an actuator. To transfer blood from a sample collection container to a testing device, a user places the sample collection container over the receiving element and inserts the testing device into an outlet of the fluid control module. The user then pushes a lever or otherwise actuates the actuator, which automatically withdraws a predetermined volume of blood from the sample collection container and transfers it to the testing device positioned at the outlet of the fluid control module.
