  • Plunger rod for arterial blood collection syringes
    Patent number: 7351228
    Abstract: An arterial blood collection device is provided having a one-piece plunger rod for use with a blood collection syringe. The plunger rod is hollow, with a closed front end. A self-sealing filter is provided within the closed front end of the plunger rod. Vents are spaced radially about the front end of the plunger rod for fluid communication into the hollow interior thereof. The plunger rod is intended for use in slidable communication within a syringe barrel. In use, the plunger can be retracted within the syringe barrel to form a cavity therein. Upon arterial blood contact, the cavity fills with blood and air can be expelled from the cavity through the vents and the filter and out to ambient air. The plunger rod is a one-piece assembly, eliminating the need for a separate rubber plunger seal.

  • Syringe tip cap
    Patent number: 6491667
    Abstract: The present invention is a syringe tip cap comprising a bottom portion, a top portion, an annular skirt extending therebetween and a plug that projects proximally from the bottom portion so as to be telescoped into the passage of a syringe tip. The plug provides means to allow air to be vented from the syringe with contacting the user. The syringe tip cap of the present invention also provides the user with an indication by tactile and visual feedback that the syringe has been vented.
