Adjustable lancet and test cartridge for automated medical sample collection and testing

An automated method of massaging a finger after a lancet of a sample collection and testing device pricks the finger, the sample collection and testing device comprising a lancet housing encompassing the lancet, a massager wheel, a first shaft connected to the massager wheel, a pressure bar, and a second shaft connected to the pressure bar, the method comprising:

• by a processor of the sample collection and testing device:
• moving the lancet housing by an incremental distance;
• determining that the lancet housing has not touched the finger of the person;
• repeating the moving of the lancet housing by the incremental distance until determining that the lancet housing has touched the finger;
• moving the lancet housing away from the finger by a predetermined distance to relieve pressure on the finger;
• triggering the lancet to prick a finger of a person;
• after triggering the lancet, swinging the first shaft in a pendulum like movement to make one or more contacts between the massager wheel and the finger at a location close to an area on the finger that is pricked by the lancet;
• and
• moving the second shaft toward and away from the finger one or more times to apply pressure to a side of the finger.
