    Abstract: A needle assembly includes a transparent or translucent housing with a fluid inlet and outlet end, a flashback chamber, and a venting mechanism therebetween. The venting mechanism includes a blocking member to control the fluid flow in the venting mechanism so that it flows along the longest path through the vent. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle tip on withdrawal from the patient.

    Abstract: Needle support assembly for a venous blood collection device with evacuated vial, comprising a support body 10 having a coupling seat 11 for a vein needle V and coupling seat 12 for a vial needle F. The support body is provided with an inner chamber 20 having an entrance 21 and an exit 22. The support body is made at least partially in transparent or semi-transparent material to permit the visualisation of the blood flow. The inner chamber has a mean cross - section greater than the cross - sections of both the coupling seats and is divided into compartments communicating with each other which define one or more channels 41, 42 for the blood flow from the entrance to the exit. Each channel defines a path for the blood which moves away from the straight line connecting the entrance and the exit and has a smaller cross - section than the mean cross - section of the inner chamber.

    Abstract: A peripheral intravascular catheter assembly (201) comprising a tubular introducer needle (211) and an adapter (209) connected to the proximal end of the light guide (210). An introducer needle (211) comprises a connection hub (206) and a needle member (202). The needle member (202) has a lumen (212), a distal end (204) and a proximal end (205). The assembly (201) may be further provided with a cannula tubing (203) surrounding at least a portion of the needle member (202), with at least one light source (312, 312a) and with an electronic module (301), configured to power the light source. The light guide (210) has a distal end and a proximal end and extends along the lumen of the needle member (202). The adapter may be connected to the electronic module (301) to the connection hub (206) of the introducer needle (211) so that light emitted by at least one light source (312, 312a) is capable of entering the light guide (210), but blood flowing through the lumen (212) of the needle member (202) is prevented from contacting said light source (312, 312a).

    Abstract: A needle hub (36) and catheter assembly are (20) disclosed herein. The needle hub includes an introducer needle (30) having a lumen extending therethrough. A needle hub is coupled to a proximal end of the introducer needle. A flash chamber (34) is removably coupled to the needle hub or the introducer needle. An interior of the flash chamber is in fluid communication with the lumen of the introducer needle when the flash chamber is coupled to the needle hub or the introducer needle. As such, the flash chamber can collect a sample of blood that can be accessed when the flash chamber is removed. In some instances, the blood can also be dispensed from the flash chamber into a test strip (70) or other testing device.
