Biological fluid collection device and biological fluid collection system

A biological fluid collection device, comprising:

• a housing having a sidewall, a top wall, a bottom wall, a receiving port extending in a radial direction of the housing and defined between the top wall and the bottom wall, a housing flow channel, and an inlet port, the housing flow channel in fluid communication with the inlet port;
• a puncturing element at least partially disposed within the housing and transitionable between a pre-actuated position wherein the puncturing element is retained within the housing and a puncturing position wherein at least a portion of the puncturing element extends through the inlet port of the housing for establishing fluid communication with the housing flow channel;
• and
• a cartridge removably connectable to the receiving port of the housing between the top wall and the bottom wall, the cartridge defining a cartridge flow channel therein,
• wherein the cartridge comprises a pair of resiliently deflectable arms releasably engagable with and removable from the receiving port of the housing for securing the cartridge to the housing,
• wherein each of the pair of arms includes a base that engages an interference surface disposed within the receiving port and a free end extending away from the receiving port,
• wherein, upon deflection of the free end of the arms, the engagement between the base and the interference surface is released and the cartridge is disconnected and removable from the housing,
• wherein, with the cartridge connected to the housing, the cartridge flow channel is in fluid communication with the housing flow channel, and
• wherein, with the cartridge disconnected from the housing, the cartridge flow channel is sealed.
