Device for continuously detecting blood parameters

A device for continuously detecting blood parameters, comprising:

• a catheter adapted to be introduced, with a free end thereof, into an artery of a patient;
• a sensor arranged on said catheter for detecting blood parameters;
• a tube adapted to be coupled to a vein of the patient;
• and
• a device for controllably maintaining a bloodstream from the artery via said sensor and said tube into the vein, said device for controllably maintaining a bloodstream from the artery via said sensor and said tube into the vein comprising:
• a first branching member, a first arm of which extends to the catheter, through a second arm of which a sensor cable connected to the sensor extends, and a third arm of which is connected to a rinsing device used for supplying a rinsing solution;
• and
• a second branching member, a first arm of which extends to said first branching member, through a second arm of which the sensor cable extends to a monitor for blood parameter values, and a third arm of which serves to drain blood from the blood vessel.

A device for continuously detecting blood parameters, comprising:

• a catheter adapted to be introduced, with a free end thereof, into an artery of a patient, wherein the catheter, which is adapted to have its free end introduced into an artery of a patient, is a double-lumen catheter comprising two lumina;
• a sensor arranged on said catheter, wherein the sensor is arranged in one lumen of said double-lumen catheter;
• a tube adapted to be coupled to a vein of the patient;
• and
• a device for controllably maintaining a bloodstream from the artery via said sensor and said tube into the vein;
• wherein
• a first lumen of said double-lumen catheter is connected to a pressure transducer and a device for supplying a rinsing solution;
• and
• a sensor cable, which is connected to the sensor, extends through a second lumen of said double-lumen catheter;
• and
• said device further comprises a branching member comprising a first arm which extends to the second lumen of the double-lumen catheter, a second arm through which the sensor cable extends to a monitor for blood parameter values, and a third arm which serves to drain blood from the artery.

• a sensor arranged on said catheter for detecting blood parameters;
• a tube adapted to be coupled to a vein of the patient;
• and
• a device for controllably maintaining a bloodstream from the artery via said sensor and said tube into the vein;
• wherein the device for controllably maintaining a bloodstream has Luer-lock connection ends and wherein these Luer-lock connection ends are provided with special transition adapters, which, when connected to a Luer-lock connection, will fill an enlarged lumen located in an area of the Luer-lock connection in such a way that, in the connected condition, a homogeneous free interior lumen will be obtained in a connection area of the Luer-lock connection, said interior lumen having a free cross-section which is reduced to the interior diameter of a shunt connection.

A device for continuously detecting blood parameters, comprising:

• a catheter adapted to be introduced, with a free end thereof, into an artery of a patient;
• a sensor arranged on said catheter for detecting blood parameters;
• a tube adapted to be coupled to a vein of the patient;
• and
• a device for controllably maintaining a bloodstream from the artery via said sensor and said tube into the vein;
• wherein the device for controllably maintaining a bloodstream has, without including the arterial and any venous catheters, a uniform interior diameter throughout a whole shunt path even across all connecting an branching members, deviations of the diameter of individual connecting and branching members from the uniform interior diameter which do not exceed 30% being still regarded as uniform interior diameter;
• wherein the interior surface of the device for controllably maintaining a bloodstream is coated with an antithrombotic coating;
• and
• wherein branching members in a shunt are non-releasably connected to hose elements of the shunt.
