Disclosed are systems and methods for use of an inductive link for a communication channel in a transcutaneous energy transfer system. An example system may include a resonant circuit associated with an external primary, a power transistor connected to the resonant circuit and configured to drive the resonant circuit with a first time-varying electrical signal having a frequency, and a power driver connected to the power transistor that is configured to set the frequency of the first time-varying electrical signal to a resonant frequency to enable power transfer from the external primary to an implanted secondary. The example system may further include a communication driver operatively connected to the power transistor and configured to encode the first time-varying electrical signal with a data signal by modulating an attribute of the time-varying electrical signal as electrical power is transferred from the external primary to the implanted secondary.

Data communication in a transcutaneous energy transfer system

A test cartridge for evaluating biological fluids can have a sensor flow cell defining a flow path for selectively passing a test fluid or biological fluid across a sensor to evaluate the sensor or the biological fluid. The test cartridge can include a sample port and at least one deformable reservoir, both formed as part of the test cartridge and fluidly connected to the flow path upstream of the sensor. A biological fluid can be manually fed into the flow path through the sample port for evaluation by the sensor. Before the biological fluid is fed through the sample port, the deformable reservoir can be manually ruptured to pass the test fluid contained within the reservoir across the sensor to first evaluate the sensor. In an example, the deformable reservoir can include a first reservoir containing a liquid quality control (LQC) fluid and a second reservoir containing a calibration fluid.

Point of care device

Disclosed are systems and methods for use of an inductive link for a communication channel in a transcutaneous energy transfer system.

A point-of-care system that can include a contact pad on a printed circuit board and a connector assembly for retaining a lead and positioning the lead in contact with the pad on the printed circuit board and with interfaces of a cuvette. The connector assembly can include a base component and a clamp component, where the base component can define at least one recessed track for receiving each lead. The clamp component can be secured to the base component to clamp the at least one lead between the base component and the clamp component without flux or solder. The connector assembly can be secured to the printed circuit board without flux or solder.

Solderless edge connector

A system for operating at least first and second amperometric sensors includes a cartridge and a control device. The cartridge includes a first amperometric sensor and a second amperometric sensor. The first amperometric sensor is in fluid flow communication with a liquid sample inlet and includes a first electrode. The second amperometric sensor is in fluid flow communication with a liquid sample and includes a second electrode. The control device sets the first and second electrodes to about the same potential such that the first and second amperometric sensors can be operated simultaneously.

Apparatus and method for analytical determinations using amperometric techniques

A portable device that includes a plurality of test modules for analyzing preselected concentrations of various body fluids of a patient. The portable diagnostic device interfaces and utilizes disposable cartridges and reagent diagnostic test strips and other fluid sample diagnostic devices to determine the amounts of preselected parameters in a patient's blood through either electrochemical, electrical, optical, or mechanical analysis. The disposable fluid sample diagnostic devices may include sample chambers with inlet ports, electrical, physical, or chemical sensors, in situ calibration media, a plurality of electrical interface terminals, and temperature control elements. An electrical interface interconnects the various test modules with one or more corresponding integrated circuits which in turn are electrically coupled to a common interactive display, printer, power supply, and communication ports.

Portable immediate response medical analyzer having multiple testing modules

A portable system for analysis of blood or other bodily fluids removable from a patient is disclosed. The system includes a temperature sensing device and a temperature control circuit. The temperature sensing device senses a temperature of a surface of a sensor substrate of a cartridge having an electrical heater device without direct contact with the cartridge or direct exposure to the heating device. The temperature sensing device also generates an electrical signal related to the sensed temperature. The temperature control circuit controls an electrical input to the heater device based on the sensed temperature and a designed control temperature.
