Abstract:
A closed specimen collection system for urine includes a port tube with a one-way valve adapted to fit a shaped nozzle that is attached to tubing ofto an indwelling urinary catheter A collection tube has a shaped nozzle at the proximal end adapted to fit sealably into the port tube adjacent the one-way valve. A specimen collection system for blood samples includes a collection tube that has a shaped nozzle adapted to fit sealably into a port connected to a centrally inserted venal catheter. Both versions use a specimen container with a hollow body, a front end with a sealable aperture that attaches to the end of the collection tube A piston fits closely within the hollow body and is attached to an actuating rod. When the actuating rod is retracted, urine or blood will flow into the specimen container through the collection tube in a sterile condition.
Abstract:
A sensor system for use with an infusion system may include at least one sensor disposed within a catheter, the at least one sensor comprising at least one of an optical sensor, an electrical sensor or a chemical/biochemical sensor. The sensor system may instead include a sample cell that is in fluid communication with the infusion system, which sample cell may be used with an analyzer to determine a patient's condition. The sensor system may be integrated with a control system for an infusion pump to control operation of the pump.
Abstract:
A portable sampling or testing device for pharmacokinetics and physiology studies and a method for using the device in conducting tests on stationary or moving animals, or human test subjects, is disclosed. The device includes an apparatus for conducting a test on a freely moving subject, or a device which may be moved by a technician to be positioned over an immobile subject, such as a premature infant or unconscious human subject in an intensive care ward. The device is designed and sized to be mobile. The device may include an uninterruptible power supply. The method provides for sampling bodily fluids or acquiring physiological readings from the test subject. The method provides for removal of body fluids with or without reintroduction of the withdrawn bodily fluids back into the freely moving subject.
Abstract:
The present invention is directed to the parenteral procurement of bodily-fluid samples. The present invention is also directed to systems and methods for parenterally procuring bodily-fluid samples with reduced contamination from dermally-residing microbes. In some embodiments, a bodily-fluid withdrawing system is used to withdraw bodily fluid from a patient for incubation in culture media in one or more sample vessels. Prior to withdrawing bodily fluid into the one or more sample vessels for incubation, an initial volume of withdrawn bodily fluid is placed in one or more pre-sample reservoirs and is not used for the incubation in culture media.
Abstract:
The present invention relates generally to systems, apparatuses, and methods for obtaining a fluid sample from a patient. In particular, the present invention relates to a various types of fluid access interfaces for enabling contact between a patient blood sample and blood parameter sensors for the measurement of physiological parameters and blood constituents.

Abstract:
A device for determining a value of a physiological parameter of a body fluid of a body under investigation, the device comprising a fluid reservoir for containing a perfusate fluid, a body interface insertable into the body under investigation for a fluid communication between the fluid reservoir and the body fluid, a fluid conduit between the fluid reservoir and the body interface, a bidirectional fluid transport unit for transporting the perfusate fluid from the fluid reservoir through the fluid conduit and the body interface into the body under investigation and for subsequently transporting a mixture of the perfusate fluid and the body fluid from the body under investigation through the body interface into the fluid conduit, and a sensor for sensing the value of the physiological parameter based on an analysis of the mixture of the perfusate fluid and the body fluid.
Abstract:
A system for continuous measurement of a blood characteristic comprising: an arterial venal shunt, at least a portion of which appears externally to a subject, the arterial venal shunt arranged to carry blood of the subject; at least one of a spectral measurer and a contact measurer operable on the blood within the externally appearing portion; a computing device receiving an output of the at least one of a spectral measurement means and a contact measurement means; and an injection device responsive to an output of the computing device, the injection device being operable to inject a pharmaceutical from a pharmaceutical reservoir, wherein the computing device responsive to the output of the at least one of a spectral measurer and a contact measurer is operable to output a signal to the injection device, the injection device being operable to inject a measured amount of pharmaceutical responsive to the signal.
Abstract:
A substantially automatic blood parameter testing apparatus for obtaining a blood sample and determining the concentration of at least one analyte is connected to a venous or arterial access line and further comprises a pump fixedly attached to a tube originating from the vascular access point; a valve fixedly attached to the tube and located above the pump mechanism; at least one measurement element; a needleless port; and an electronic meter. In addition, the automated blood parameter testing apparatus may be integrated into a complete system, further including a monitor and a central monitoring station.
Abstract:
A catheter for insertion into a blood vessel, the catheter having a sampling part (6) arranged to capture a blood sample at a plurality of locations along a length of the blood vessel and an apparatus arranged to analyse blood taken from a plurality of locations along the length of the blood vessel and to provide a profile of concentration levels along the length of the blood vessel.
