20090007642 | DIALYSIS FLUID MEASUREMENT METHOD AND APPARATUS USING CONDUCTIVE CONTACTS - A dialysate testing method in one embodiment includes placing electrical contacts in a dialysate flow path, measuring an electrical property of the dialysate as it flows through the flow path and past the contacts, and determining whether the dialysate has been mixed properly from the detected electrical property. A dialysate testing method in another embodiment includes flowing dialysate past a pair of electrical contacts, calculating a conductivity of the dialysate using an algorithm that takes into account a geometry of the contacts, and using the calculated conductivity to determine if the dialysate has been removed properly. | 01-08-2009 |
20090009764 | METHOD AND APPARATUS FOR MEASURING THE PRESENCE AND CONCENTRATION OF PHARMACEUTICAL SUBSTANCES IN A MEDICAL FLUID ADMINISTERED BY A MEDICATION DELIVERY SYSTEM - 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. | 01-08-2009 |
20090012452 | DIALYSIS FLUID MEASUREMENT SYSTEMS USING CONDUCTIVE CONTACTS - 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. | 01-08-2009 |
20090082649 | ACCESS DISCONNECT SYSTEM WITH OPTICAL AND OTHER SENSORS - 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. | 03-26-2009 |
20120105850 | CASSETTE-BASED METHOD AND APPARATUS FOR MEASURING THE PRESENCE AND CONCENTRATION OF PHARMACEUTICAL SUBSTANCES IN A MEDICAL FLUID - 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. | 05-03-2012 |
20120296279 | ACCESS DISCONNECTION METHOD USING OPTICAL AND OTHER SENSORS - A method for detecting movement or disconnection of a needle at an access site of a patient comprising: sensing for a presence of blood at the access site while a medical procedure is performed on the patient; separately sensing for a movement of (i) the needle or (ii) tubing connected to the needle; and sending a signal indicating movement or disconnection of the needle if one of (a) the presence of blood is sensed or (b) movement is sensed under (i) or (ii). | 11-22-2012 |

20080243057 | FLUID DELIVERY SYSTEM AND FLOW CONTROL THEREFOR - 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. | 10-02-2008 |

20100275364 | Accessible Bathtub - A bathtub system, including a tub with a bather access opening in one sidewall and a door mounted on that sidewall. In the closed position, the door is adjacent the access opening, and in the open position the door is substantially clear of the access opening. The system includes a gray water reservoir under the tub of approximately the capacity of the tub and which can be connected to a sewer system. A high capacity tub drain conducts water from the tub into the reservoir by gravity alone very quickly. | 11-04-2010 |
