  • Patent number: 5611782
    Abstract: A method of delivering blood to an evacuated receptacle having a pierceable stopper and a cavity at a subatmospheric pressure, comprising the steps of:a) providing a syringe comprising a barrel having an open proximal end, a distal end and a chamber, a needle cannula having a sharp distal end and a lumen therethrough connected to the distal end, a shield having an open distal end slidably mounted over the barrel for telescoping movement from a proximal position where the needle cannula projects through the open distal end of the shield to a distal position where the shield surround the needle cannula, a piston inside the barrel;b) providing a catheter having a distal end and a passageway therethrough and a housing having a port in fluid communication with the passageway, a pierceable septum sealing the port;c) placing the distal end of the catheter in a blood vessel;d) piercing the pierceable septum with the needle and drawing blood from the vessel through the catheter, and into the chamber by manipulating th

  • Patent number: 5439450
    Abstract: A method of delivering a blood sample to an evacuated receptacle having a pierceable stopper and a cavity at a subatmospheric pressure, comprising the steps of:a) providing a syringe comprising a barrel having an open proximal end, a distal end and a chamber for retaining fluid, a needle cannula having a sharp distal end and a lumen therethrough connected to the distal end, a safety shield having an open distal end and a cap having an aperture removably connected thereto, the shield slidably mounted over the barrel for telescoping movement from a proximal position where the needle cannula projects through the aperture to a distal position where the shield protectively surrounds the needle cannula, a piston inside the barrel connected to a rigid elongate plunger rod;b) piercing a blood vessel with the needle and drawing blood from the vessel into the chamber by manipulating the plunger rod,c) withdrawing the needle from the vessel;d) moving the shield to the distal needle protecting position;e) removing the ca
