摘要： 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.

摘要： An access disconnection method includes supporting a transmitter including a wireless communication apparatus, a receiver, a portion of an arterial line, a portion of a venous line and electronic circuitry by a member separate from a blood treatment machine. The method further includes operably communicating the electronic circuitry with the transmitter and the receiver, enabling transmission of a wave from the transmitter in one of the arterial and venous lines, enabling receipt of the wave by the receiver in the other of the arterial and venous lines, and enabling a disconnection output to be sent to the blood treatment machine via the electronic circuitry. The disconnection output is indicative of a change in the wave received by the receiver from the transmitter sufficient to expect that an access site disconnection of one of the arterial and venous lines has occurred.

摘要： An extracorporeal therapy machine removes blood from a patient in order to treat the blood and then return the blood to the patient. If the removal needle or the return needle is dislodged and blood is not returned, the patient may suffer a great blood loss. A new technique for detecting dislodgement uses the normal, initial values of a plurality of parameters of the patient and the therapy machine to set criteria or limits for an alarm, and then adjusts those criteria based on the later values of those parameters as they change during one therapy or over several therapies experienced by the patient.

摘要： A blood detection system is used to detect blood in a patient undergoing an extracorporeal blood therapy, such as hemodialysis or apheresis. The blood detection system uses a digital video device, which may be a camera, such as a standard digital video camera, a low light camera, an infrared camera, or a night vision camera. The digital image is sent to a computer with image processing and pattern recognition software. The software is used to detect whether a pool of blood is forming at the access site. The system is able to detect a pool of blood atop the access site, such as when a leak or a dislodgement of a needle occurs. The system is also able to detect pooling of blood under the skin, as a result, for instance, infiltration of an arteriovenous fistula.
