1. A collector for collecting fluid from a subject, the collector comprising:
- a housing having a base and an elongate guide, wherein the housing defines a lumen, and wherein a distal surface of the base is configured to be positioned against a skin surface of the subject;
an actuator positioned at least partially within the lumen and having an actuator arm, wherein a distal portion of the elongate guide and a distal portion of the actuator arm together define a locking feature, and wherein the actuator is configured to be moved through the lumen toward the base;
a platform positioned at least partially within the lumen between the actuator and the base, wherein the platform includes a platform projection configured to engage the locking feature;
anda plunger operably coupled to the platform and having a lancet,wherein the actuator is movable from (a) a first position relative to the base in which the lancet extends past the distal surface of the base and (b) a second position nearer to the base than the first position in which the lancet is withdrawn into the lumen of the housing, andwherein movement of the actuator from the first position to the second position moves the platform projection out of engagement with the locking feature to permit the platform to move through the lumen relative to the actuator in a direction away from the base.
