Abstract: A fluid sampling device and a method is provided for collecting body fluid samples such as blood without the intervention of medically trained personnel. The body fluid sampling device having a sample containment chamber made of a material having a thermal inertia permitting the maintenance of sample temperature over a known period of time. Optionally an isolating cover or sleeve may slide in place by a mechanism triggered by thermal contraction of an element after the device has reached a sufficiently low temperature in a patients refrigerator. Associated methods are provided to ensure hermetic transport of the collected body fluid sample to an analysis lab. Also disclosed is a device and app combination for drug or vaccine injection, the app including means to allow for verification of the patient's ID and/or the particular device used.
