Needle assembly having the following modes of operation; a first mode wherein the safety shield can move to a first retracted position allowing injection of the piercing portion of needle from a position at least partially covering the piercing portion of the needle and a second mode wherein the safety shield moves to a position protecting the piercing portion of the needle after the first mode and is prevented from moving back to a position exposing the piercing portion of the needle.

A specimen collection assembly including a flow control member for adjustably altering a flow path is disclosed. In one configuration, the flow control member defines a regulation channel in fluid communication with a lumen of a cannula, wherein the flow control member is configured to adjustably alter an effective flow distance between the lumen of the cannula and an interior of an evacuated collection container. In another configuration, the flow control member is positioned to vary an effective cross-sectional area of at least one of an inlet port and an outlet port adapted to be in fluid communication with the lumen and the evacuated collection container.

A needle adapter may include a body, which may include a distal end and proximal end. The needle adapter may include a needle extending through the body. The needle may include a distal tip and a proximal tip. The distal tip may extend distal to the distal end of the body. The proximal tip may extend proximal to the proximal end of the body. The needle assembly may include a sheath coupled to the body and extending over the proximal tip. The needle assembly may include a hydrophobic vent element surrounding the body. The needle assembly may include a septum coupled to the distal end of the body.

An analysis unit formed by an analysis body housing an analysis chamber and having a sample inlet and a supply channel configured to fluidically connect the sample inlet to the analysis chamber. Dried assay reagents are arranged in the analysis chamber and are contained in an alveolar mass. For instance, the alveolar mass is a lyophilized mass formed by excipients and by assay-specific reagents.

An apparatus for performing phlebotomy through a peripheral intravenous line. The apparatus includes an introducer and a catheter configured to advance the catheter through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the catheter and place in fluid communication with the peripheral intravenous line. When advanced the catheter is configured to transport a bodily fluid (i.e. blood) to a volume outside of the body.

A system and method for preparing a diagnostic fluid sample for use with a fluid assay system. The method comprises the steps of: amplifying the fluid sample to increase the number of cells subject to being tested; drawing a first volume of the fluid sample into a first syringe of a dual-barrel syringe and dispensing the first volume of the fluid sample through a media filter. The method further comprises the steps of placing the bacteria-laced filter into a lysis module; dispensing a first portion of a lysis buffer into the lysis module from the second syringe of the dual-barrel syringe; and dispensing a second portion of the lysis buffer through the media filter into a disposable cartridge of a fluid assay system.

A biological fluid collection device that receives a sample and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection device of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection device of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications.

A shieldable needle device (12) with a needle cannula (28), a hub (44) supporting the needle cannula, and a tip guard (24) axially movable along the needle cannula where, upon transition, the tip guard protectively surrounds the distal end (42) of the needle cannula. The needle device includes a pair of wings (60) extending laterally from opposing sides of the tip guard and connected to the hub. The pair of wings are transitionable between a first position and a second position, wherein transition of the pair of wings advances the tip guard from a proximal position to a shielding distal position. The wings include protrusions (66) which cause the longitudinal axis of the needle cannula to become offset from the opening (52) of the tip guard during advancement of the tip guard preventing the needle cannula from being reinserted through the tip guard after the tip guard has been transitioned to the distal position.

A medical needle holder (10) having a generally hollow body (18) which extends in the direction of an axis (62) from a first end (20) to a second end (22). The first end is shaped for reception of a needle (50) therein and the second end is open to allow for insertion of a fluid receptacle (16). The first axis is substantially aligned in use with a needle positioned in the first end of the body. The needle holder comprises a grip portion (28) which extends outwardly from the body in a direction which is angularly offset from the first axis. The grip portion may be actuable between an in-use condition and a disposal condition in which the grip portion covers a needle in the needle holder. The body (18) may comprise control formations on its inner surface to allow for control over the insertion of a fluid receptacle (16) into the body.

Systems and methods for autonomous intravenous needle insertion are disclosed herein. In an embodiment, a system for autonomous intravenous insertion include a robot arm, one or more sensors pivotally attached to the robot arm for gathering information about potential insertion sites in a subject arm, a medical device pivotally attached to the robot arm, and a controller in communication with the sensors and the robot arm, wherein the controller receives the information from the sensors about potential insertion sites, and the controller selects a target insertion site and directs the robot arm to insert the medical device into the target insertion site.
