摘要： A biological specimen collection instrument configured for collecting a biological specimen to be analyzed includes: (a) a handle; (b) an elongate flexible or elastomeric stem extending from said handle, said stem having a distal portion terminating at a tip; and (c) a flexible or elastomeric lattice collection element connected to said stem distal portion, said lattice collection element having a body portion and a distal end portion, with at least said body portion, and optionally said distal end portion, having openings therein in a configuration that forms at least one biological specimen collection space.

摘要： A method of making a plurality of polymer dental appliances, including the steps of: (a) additively manufacturing a plurality of hollow molds from a polymerizable resin, each mold having an external surface portion configured in the shape of a dental arch and a bottom portion having a hollow cavity therein, and with the additively manufacturing step carried out with the plurality of hollow molds formed on a build platform; (b) centrifugally separating residual resin from both the external surface portion and the bottom portion (including the hollow cavity) of each mold; (c) further curing, concurrently or sequentially, the external surface portion and the bottom portion of each mold with ultraviolet light; then (d) thermoforming a thermoplastic polymer sheet on each hollow mold external surface portion to produce the plurality of polymer dental appliances; and (e) separating the plurality of polymer dental appliances from the plurality of hollow molds.
