Pumps in wearable ultrafiltration devices: pumps in wuf devices.
The wearable artificial kidney (WAK) is a device that is supposed to operate like a real kidney, which permits prolonged, frequent, and continuous dialysis treatments for patients with end-stage renal disease (ESRD). Its functioning is mainly related to its pumping system, as well as to its dialysate-generating and alarm/shutoff ones. A pump is defined as a device that moves fluids by mechanica...
متن کاملAn acoustic streaming instability in thermoacoustic devices utilizing jet pumps.
Thermoacoustic-Stirling hybrid engines and feedback pulse tube refrigerators can utilize jet pumps to suppress streaming that would otherwise cause large heat leaks and reduced efficiency. It is desirable to use jet pumps to suppress streaming because they do not introduce moving parts such as bellows or membranes. In most cases, this form of streaming suppression works reliably. However, in so...
متن کاملInlet and outlet devices for rotary blood pumps.
The purposes of inlet and outlet devices for rotary blood pumps, including inducers and diffusers for axial pumps, inlet and exit volutes for centrifugal pumps, and inlet and outlet cannulas, are to guide the blood into the impeller, where the blood is accelerated, and to convert the high kinetic energy into pressure after the impeller discharge, respectively. The designs of the inlet and outle...
متن کاملThe path to wearable ultrafiltration and dialysis devices.
Wearable blood processing devices offer an attractive solution to problems inherent in clinic-based, intermittent end-stage renal disease therapies. What is involved in transitioning even a part of the current clinic-based population to ambulatory therapy has not been clearly enumerated. This paper addresses what a first-generation wearable device might accomplish, how issues of safety will nee...
متن کاملWearable Medical Devices
A wearable medical device can be defined as a device that is autonomous, that is noninvasive, and that performs a specific medical function such as monitoring or support over a prolonged period of time. The term ‘‘wearable’’ implies that the support environment is either the human body or a piece of clothing. Handheld and portable devices are therefore not strictly speaking wearable, but this d...
