Multilumen catheter
First Claim
1. A multilumen catheter comprising:
- a first tubing;
a plurality of lumens disposed within the first tubing, each lumen of the plurality of lumens having a first end and a second end, said plurality of lumens include a sensor lumen;
a plurality of second tubings;
a junction element maintaining a connection between the first end of each lumen of the plurality of lumens and a corresponding second tubing of the plurality of second tubings; and
a sensor lead having a sensing element that extends through the sensor lumen;
wherein the sensor lumen has a shape and size that provides a compression fit for the sensor lead; and
wherein the sensing element is able to exit the first tubing at an end of the first tubing and is able to extend past the end of the first tubing and is able to extend past the second end of each lumen of the plurality of lumens.

Abstract
A multilumen catheter having tubings extending into lumens within the catheter. The lumens may be used for blood, drugs or other medicants. The lumens may also be used for sensors. The junction element, external to the patient, connects the tubings to the lumens. The tubings, also external to the patient, connect to infusion members, to which one or more infusion systems may be connected to deliver blood, drugs and other medicants to the patient. A sensor having a sensing element may extend through the sensor lumen and be positioned internal to the patient for physiological parameter sensing. An external portion of the sensor may be connected to associated electronics to provide automatic monitoring of the physiological parameters and automatic delivery and control of the infusants. Also, a central line catheter for delivering fluids directly into a main artery or vein near the heart, which contains a first lumen to deliver a fluid through the central line catheter and a second lumen containing a sensor capable indicating a characteristic level in blood. The first lumen delivers the fluid downstream of the sensor to prevent any interference between the fluid delivery and the sensor readings. In other versions, the central line catheter can have additional lumens for additional purposes. In addition, the central line catheter can further include a flush sleeve to remove debris around the sensor.

25. A system in an intensive care unit, the system comprising:
-
a central line catheter, the central line catheter comprising; a sensor lead having a sensing element capable of indicating a characteristic level in blood; a first lumen for delivering fluid to a body of a patient, the first lumen having an exit site at which the fluid is able to exit into the body of the patient; and a second lumen for containing at least a portion of the sensor lead, the second lumen having an end that is adapted to be located in the body of the patient when the first lumen is delivering the fluid to the body of the patient; an infusion device for delivering the fluid through the first lumen; and a monitoring device for displaying readings obtained by the sensor; wherein the sensor is able to extend past the exit site of the first lumen and is able to extend past the end of the second lumen; and wherein the second lumen has a generally oval shape that provides a compression fit for the sensor lead. - View Dependent Claims (26, 27)
