Biological sample collection, storage, and transport system and method

摘要

A cytological cell sample collection, storage, and transport device is disclosed. The device comprises a sheath, a collection assembly, a base, and a containment vial. The collection assembly is slideably coupled to the base to expose a swab head comprising the collection assembly. The containment vial may be configured to enclose the sheath and collection assembly within the internal volume defined by the containment vial and the base.

主权项

1. A system for biological sample collection comprising:
a collection assembly, a sheath, and a base; wherein the collection assembly comprises a support shaft, a swab head, and a plunger, wherein the swab head mechanically couples to a distal support shaft end and the plunger couples to a proximal support shaft end; a distal sheath end of the sheath forms an expandable opening configured to define a first circumference when the distal sheath end is in a closed position and a second circumference when the distal sheath end is in an open position, such that the first circumference is smaller than a circumferential profile of the swab head and the second circumference is larger than the circumferential profile of the swab head; and a base coupled to a proximal sheath end, the base comprising a stop channel, wherein the stop channel is shaped to match a radial profile defined by the plunger, such that a radially outward facing plunger surface contacts a radially inward facing stop channel surface when the plunger is disposed within the stop channel.
