  • Publication number: 20160081606
    Abstract: A regulator for modulation of the flow rate of blood out of a patients blood vessel during blood collection is disclosed. The regulator includes a housing having a housing inlet, a housing outlet, and a wall defining a housing interior. At least a portion of the wall includes a flexible member. A valve is associated with the flexible member and is in communication with the housing interior. The regulator is designed so that upon an application of a differential pressure within the housing interior, the flexible member and/or valve automatically move with respect to either the housing inlet or housing outlet to modulate a flow of blood moving through the housing. A manual over-ride device can be provided to enable a user to over-ride the automatic regulation and manually regulate the flow of blood through the housing.

  • Patent number: 9271668
    Abstract: A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

  • Publication number: 20120191067
    Abstract: The invention relates to an injection device (110) with a luer fitting. The injection device has a compressible syringe body (137) defining a reservoir (146). A male luer fitting (150) has a channel (152) therethrough for conducting contents of the reservoir, and a luer tip at an end of said male luer fitting opposing said base end. A first connecting structure (182) is arranged on said male luer fitting between said base end and said luer tip. A shield cap (160) is arranged on the male luer fitting. The shield cap has a second connecting structure interacting with said first connecting structure to prevent inadvertent movement of said shield cap relative to said male luer fitting when said shield cap is arranged at said first position. A first seal (170) is provided for sealing said channel at said luer tip. A second seal (180) is arranged between said shield cap and said male luer fitting for sealing the outer surface and the luer tip of said male luer fitting from outside contamination.
