Abstract

Devices and methods for withdrawing bodily fluid from a subject are disclosed herein. In some embodiments, a handheld device can include a housing having an opening, a skin-piercing assembly, and an actuator coupled to the skin-piercing assembly. The skin-piercing assembly can include a casing, a drive member pivotably mounted within the casing and carrying a blade, and a biasing member coupling the drive member to the casing. The actuator can be movable relative to the housing from a first position to a second position. In the first position, the drive member can engage the casing to maintain the biasing member in a biased configuration. Movement of the actuator from the first position to the second position can disengage the drive member from the casing to permit the biasing member to drive the blade at least partially through and/or across the opening in the base.
