An acoustic line tracing system for tracing a fluid transfer system tubing line includes an acoustic receiver operably connectable to the tubing line and configured to receive the vibratory signal. The acoustic receiver includes a vibration sensor disposed to contact the tubing line and configured for detecting vibration of the surface of the tubing line caused by the vibratory signal, and an indicator producing at least one of an audio and a visual cue when the vibration sensor detects the vibratory signal.

Acoustic line tracing system and method for fluid transfer system

A disposable set () includes a tube; and a sensing member () press-fittingly insertable into the tube, the sensing member including: a first end () having a first diameter and including at least one through hole () positioned along a perimeter of the first end; a second end () having a second diameter and including at least one through hole positioned along a perimeter of the second end, the first diameter and the second diameter being substantially equal to an interior diameter of the tube; and a middle portion () located between the first end and the second end having a diameter that is less than the first diameter, the middle portion including at least one SERS sensing element (), wherein the through holes in the first and second ends enable fluid to pass through the sensing member.

Disposable sets including raman sensors

A dialysis fluid heating system includes a plurality of conductive tubes; first and second end caps located at first and second ends of the tubes, respectively, the first end cap including a dialysis fluid inlet and a dialysis fluid outlet, the end caps and the tubes configured such that dialysis fluid can flow from the fluid inlet of the first end cap, through at least one first tube to the second end cap, and through at least one second tube back to the first end cap; a conductive wire wound around an outside of the conductive tubes; and electronics configured to supply power to the conductive wire, the wire forming a primary coil of a transformer, the tubes forming a secondary coil of the transformer.

Dialysis fluid heating systems

A fluid delivery system having a closed-loop control process for delivering a medical fluid to a patient. A fluid infusion system includes a pump for delivering a fluid to a patient via an administration tube. A flow sensor associated with the administration tube provides an indication of the actual flow rate of fluid in the administration tube. Such a flow sensor may comprise a positive displacement flow sensor constructed using micro-fabrication and/or micro-molding techniques. A reader reads the actual flow rate signal and provides an indication to a controller for controlling the pump. The flow rate information can also be used for providing status information, such as the existence of a blockage in the fluid delivery system.

Fluid delivery system and flow control therefor

A medical fluid delivery system includes a medical fluid delivery machine including a light source configured to generate a light beam; a polarizer configured to receive the light beam and to allow a portion of the light beam within the medical fluid to be transmitted through the polarizer, a photodetector to provide a measurement of an intensity of the light beam transmitted through a medical fluid and the polarizer; a medical fluid cassette operating with the medical fluid machine to pump the medical fluid, the medical fluid cassette loaded onto the medical fluid delivery machine such that the light source resides on a first side of the cassette and the photodetector resides on a second side of the cassette; and a computer configured to use the measurement of the intensity to determine whether the medical fluid can be delivered to a patient.

Cassette-based method and apparatus for measuring the presence and concentration of pharmaceutical substances in a medical fluid

A dialysis system instrument includes a dialysis instrument, a disposable pumping and valving cassette apparatus operable with pumping and valving actuators of the dialysis instrument, the disposable cassette including an electronic cell and electronics associated with the electronic cell, the electronics configured to determine an electrical property of a solution flowing through the electronic cell of the disposable apparatus.

Dialysis fluid measurement systems using conductive contacts

An optical access disconnect system is useful for detecting the presence of blood. The optical access disconnect system includes one or more optical sensors placed near an access site of a patient, the optical sensors suitable for detecting the presence of blood, especially by detecting a difference in light reflected or absorbed by blood. The optical access disconnect system may also be used as an interlock to assure compliance. A detector may be placed adjacent the access site to detect the access needle, or an object or mark on the access needle or fluid line. A therapy machine, such as a dialysis machine, may be programmed not to start or continue operation unless the needle or fluid line is detected. The detector may be one of the optical sensors, calibrated or adjusted to detect a mark on the needle or access line, or may be another type of detector.

Access disconnect system with optical and other sensors

Test equipment determines the contents of medical fluids to be delivered to a patient by a medication delivery system by measuring optical properties of the fluids. One system provides a non-invasive test that uses optical rotation caused by optically active pharmaceutical substances to determine the presence or absence of the pharmaceutical substances within a medical fluid. Another system provides a non-invasive test that uses refractive index properties to determine the concentration of a pharmaceutical substance within the fluid. A method for use is also disclosed.

A reconstitution device is disclosed and includes a first container receiver having a first component cannula disposed therein, the first component cannula having a withdrawal port and a first transfer port formed thereon, a second container receiver having a second component cannula disposed thereon, the second component cannula having a vent port and a second transfer port formed thereon, a device body coupling the first container receiver to the second container receiver and having a transfer lumen formed therein, the transfer lumen in fluid communication with the first and second transfer ports, a selectively sealing interface secured to the device body and in fluid communication with the withdrawal port, and a venting member in communication with the vent port through a vent lumen.

Reconstitution device and method of use

This invention provides a medical device for delivering volumetric quantities of a first and a second biochemically reactive fluid in which separate MBUs atomize the fluids. The device of the present invention includes a fluid delivery device for laparoscopically delivering fluids having two feed conduits for delivering fluid to feed ports of the mechanical breakup units, the mechanical breakup units having two feed ports for receiving fluid from the feed conduits and directing such fluid into spin chambers and funneling portions having a sloped sidewall for directing fluid from the spin chambers through an exit port. The device is suitably dimensioned for creating a spray of two fluids with different viscosities such as fibrinogen and thrombin in such a manner that the thrombin spray cone encompasses the fibrinogen spray cone at a distance of about one inch from the exit port with a 0.5 cc/second flow rate to avoid depositing unreacted fibrinogen on a surface. Other instruments such as optical fibers may be incorporated within the device.
