  • Method of using bilumen peripheral venous catheter with adapter
    Patent number: 4960409
    Abstract: Bilumen catheters of the present invention have tow lumens to supply two non-miscible liquids simultaneously and a method for their use. The two lumens are enclosed within a single catheter and have different cross-sections, the lumen of larger cross-section being adapted to infuse or remove higher viscosity fluids, such as blood, and the lumen of smaller cross-section designed to infuse or remove lower viscosity fluids. Catheters of this invention are more narrow than prior art catheters so that they need not be employed in the vicinity of the heart or other vital organs and may be used in peripheral portions of a patient's body, such as the patient's limbs. This invention reduces the likelihood of blood clots, dysarythmias and infection. They do not need highly trained individuals, such as doctors, for injection purposes, but may be used by any paramedic or nurse in an emergency.

  • Bilumen peripheral venous catheter with adapter
    Patent number: 4776841
    Abstract: Bilumen catheters of the present invention have two lumens to supply two non-miscible liquids simultaneously and a method for their use. The two lumens are enclosed within a single catheter and have different cross-sections, the lumen of larger cross-section not exceeding 18 gauge to infuse or remove higher viscosity fluids, such as blood, and the lumen of smaller cross-section designed to infuse or remove lower viscosity fluids. Catheters of this invention are more narrow than prior art catheters so that they need not be employed in the vicinity of the heart or other vital organs and may be used in peripheral portions of a patient's body, such as the patient's limbs.
