  • Patent number: 5154703
    Abstract: A medical device which presents the backflow of fluid therethrough is particularly useful as a bloodless catheter assembly, that is, prevents the backflow of blood through the catheter by utilization of a self-closing valve carried in a hollow catheter housing to one end of which a catheter is fixed so as to provide a fluid passage through the catheter and catheter housing. The fluid passage in the catheter housing is sealed by a self-sealing valve element extending transversely across the passage upstream from the catheter. A hollow needle is held in the catheter housing downstream of and pointed at the valve element. Attachment of a fluid dispensing medical appliance to the other catheter housing end forces the valve element downstream onto the needle so as to pierce the valve element and open a fluid passage from the catheter housing upstream of the valve element through the hollow needle to the catheter.

  • Patent number: 5114400
    Abstract: A blood withdrawal apparatus and method in which a blunt cannula or needle penetrates an elastomeric septum into a pressurized flow channel such as an arterial line. After blood is withdrawn into the attached syringe, the needle tip is withdrawn into the septum until an indication is detected, for example by engagement of a detent on a shroud surrounding the cannula or needle with a detent on the housing for the septum. The nurse can then depressurize the syringe by operating the piston and thus prevent blood spurt when the needle tip is subsequently fully withdrawn from the septum.
