Abstract: A fluid path connector assembly for a medical fluid delivery system includes a connector element having a body, a lumen extending through the body, and a pair of flexible legs connected to the body, each of the flexible legs having a flange. The connector assembly further includes a dust cap removably connected to the connector element. The dust cap includes a dust cap body positioned between the flexible legs to enclose the lumen, and an engagement element at a distal end of the dust cap body. The engagement element is in contact with the flanges of the flexible legs to prevent disengagement of the dust cap from the connector element while allowing ready removal of the dust cap by medical personnel. A removable/disconnectable tamper resistant and/or tamper-evident and/or tamper resistant feature connecting the dust cap to the connector element is also disclosed.

Abstract: A body fluid sampling device (100) provides a user with the ability to sample and/or analyze a fluid in the body (body fluid) such as blood, puss or venom. The device (100) includes at least: a body fluid reservoir for containing the sampled body fluid and a fluid extraction mechanism including at least one conduit or needle connected to a conduit injection and retraction mechanism and a vacuum reservoir. After connecting the body fluid reservoir to the sampling device, a vacuum seal of the body fluid reservoir is adapted to be broken so as to cause the sucking of the body fluid into the body fluid reservoir. The sampling device (100) aids in executing a method (200) of the invention consisting of collecting body fluid such as capillary blood samples without the intervention of medically trained personnel.
