A recently granted patent (Publication Number: US11877848B2) discloses a system designed for efficient and minimally invasive physiological sample collection. The system comprises a dermal patch with a housing that attaches to a subject's skin, featuring an opening for access to the skin. A lancet with a movable needle is included to puncture the skin for sample collection. Additionally, a fluid pouch storing processing fluid, made of a frangible membrane, and a slider to compress the pouch for rupture are integrated into the housing for streamlined sample processing.

Furthermore, the system includes a moveable pin within the housing to create a vacuum proportional to its movement, aiding in sample collection. This pin, housed in a receptacle, also serves to seal the receptacle for secure sample containment. The housing further incorporates a chamber to receive the sample and a channel in communication with the chamber and receptacle. The pin's vacuum generation within the channel facilitates the transfer of the collected sample to the chamber, enhancing the overall efficiency of the sample collection process.
