Abstract:
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.
Abstract:
Provided is a computer-implemented system and method for monitoring printer-related data on USB cables. A USB-compatible device comprising a field programmable gate array and a microprocessor is placed in-line between a non-networked computer and a printer and monitors the line for print-related data. Once detected, the print-related data is transmitted via a radio frequency to a base station. The base station subsequently compiles the print-related data and relays the data to a printer reporting system.
Abstract:
An operating machine, such as a medical machine or a dialysis machine, includes a housing for operating components of the machine and a moveable user interface or display for viewing and entering information concerning operation of the machine. Signals concerning operating information are wirelessly transmitted between the machine and the display using one of several techniques. Power is also transmitted wirelessly from the operating machine to the screen, or from a separate power source to the display. The wireless signals may be transmitted via induction, radio, infrared or optical means.
Abstract:
A dialysis machine includes a control unit having a user interface; a heater(s) located separate from the control unit; a supervisory processor located within the control unit; a delegate control processor located with the heater(s), the delegate control processor in communication with the supervisory processor and configured to receive load cell, heater(s) plate and supply bag temperature sensor inputs; and a sub-delegate heater(s) processor in communication with the control processor and configured to control power to the heater(s). The machine can also include primary and secondary monitoring processors that perform a safety check to the control processing and monitor the load cell.

Abstract:
Temperature compensation is applied to correct for temperature mismatch between a reference chamber and a disposable chamber in a pneumatic pumping system for dialysis fluid for peritoneal dialysis. The mismatch creates an error in the calculation of pumping volume of dialysate fluid. Applying a correction for the temperature mismatch helps to more precisely control the volume of dialysate that is metered to the patient. Also disclosed are ways to keep temperatures constant and to use temperature sensors to accurately measure the temperatures of the chambers. In other aspects, the temperature of the dialysate fluid itself may be measured and used to apply a correction to the volume of fluid that is pumped to the patient.
Abstract:
This invention relates to an apparatus for monitoring a locally attached printer using the locally attached printer's Ethernet interface. A USB device is installed between a computer and a locally attached printer and additional connects to the printer via an Ethernet interface. The USB device uses SNMP (or other network protocols) to manage the printer via the Ethernet interface. The system may then report the management information to a central server.
