  • Patent number: 10349880
    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.

  • Patent number: 9687843
    Abstract: A container for storing a biological sample for molecular diagnostic testing and/or histological testing is provided. The container includes a first chamber for receiving a sample holder therein, a second chamber, and a closure for enclosing the container. A breakable membrane, such as a piercable foil, extends within the container and separates the two chambers. When the breakable membrane is broken, fluid can pass between the first and second chambers. The membrane may be broken through an activator on the closure, such as a depressible member or a rotatable carrier, causing the sample holder to break through the membrane.

  • Patent number: 9295416
    Abstract: A container assembly is disclosed including an outer container, a hollow inner member, and a closure. The outer container has a closed bottom, an open top, and a sidewall extending therebetween. The hollow inner member is disposed within the outer container and has an inner surface defining at least one capillary channel. The inner member includes a first end adjacent to the open top of the outer container and has an outer periphery seated against the sidewall of the outer container. The closure has a proximal end and a distal end. The closure proximal end is seated at least partially within the first end of the inner member to seal the outer container and inner member and define a fluid collection chamber. The closure distal end defines a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.
