Abstract: A compression device particularly suited for DVT prophylaxis includes a disposable wrap and a re-usable controller removably mounted on the wrap to apply a tensioning force to the wrap when it is encircling the limb of a patient. The wrap includes a strap wrapped around an electric motor-driven pulley, with an encoder to determine the amount of rotation of the pulley and a current sensor to determine the current load on the motor during operation. A pretension protocol sets the pulley of the wrap at a proper frap position so that the wrap can properly execute a DVT prophylaxis protocol.

Abstract: A patient compliance monitoring system is provided for monitoring patient compliance in the use of a plurality of patient care and recovery devices in the hospital room. Sensors are associated with each of the devices to detect a usage history of the associated device and to generate usage data therefore. One device is a patient positioning device including a wedge-shaped body with at least one pressure sensor associated with the bottom surface. The wedge-shaped body is formed of a compressible viscoelastic open-cell foam composition that is adapted to compress under the weight so that the angle of the ramp surface of the wedge decreases from an initial ramp angle to a tilt angle for supporting the patient.

Abstract: A system for measuring electrical signals in a biological subject includes a variable gain amplifier with a predetermined transfer function that generates amplified signals corresponding to an input from electrical signals in the biological subject over a predetermined range of frequencies and amplification gain levels, an analog to digital converter generating digital data corresponding to the amplified signals, and a signal processing device receiving the digital data for the plurality of amplified signals. The signal processing device applies an inversion filter with another transfer function that is an inverse of the transfer function of the variable gain amplifier to remove an effect of the transfer function from the digital data, and generates an output signal corresponding to the electrical signals in the subject with reference to the filtered digital data.
