Abstract:
Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a source of negative pressure, a coupling circuit, a driving circuit, and a controller. The driving circuit supplies a driving signal to the source of negative pressure via the coupling circuit to cause the source of negative pressure to provide negative pressure to a wound dressing. The coupling circuit includes an inductive reactance that limits a rate of change over time of the driving signal. The controller controls the driving signal supplied by the driving circuit.
Abstract:
The present invention relates to a method for re-synchronizing a breathing pattern of a patient (16) suffering from ataxic breathing, the method including the steps of monitoring the breathing pattern of the patient (16) during sleep; detecting whether the monitored breathing pattern includes an ataxic breathing episode; and if an ataxic breathing episode is detected, ventilating the patient (16) and eliminating a spontaneous breathing of the patient (16) for a predetermined first period of time (Δt 1 ) by providing a flow of breathing gas (14) to an airway of the patient (16) with a volume of the breathing gas (14) provided per minute being above an individual-related threshold value of the patient (16).
Abstract:
A medical device with a self-sustaining power source is disclosed herein. The medical device includes e.g. a medical skin-patch type infusion pump having at least one mechanical and manual activation mechanism, e.g. comprising buttons (16, 18), for engaging the pump to cause a dose event. An energy generator, e.g. energy harvesting system based on a piezo crystal (402) mechanically coupled to a fixed portion (24) of the medical pump, coupled to the activation mechanism generates energy each time the activation mechanism is actuated. The generated energy is supplied to a dose counter of the infusion device.
Abstract:
Introduced are methods and systems for: gathering human biological signals, such as heart rate, respiration rate, or temperature; analyzing the gathered human biological signals; and controlling a vibrating pillow strip based on the analysis.
Abstract:
A wearable apparatus capable of altering a physiological parameter such as the heart rate of a user to provide a relaxing or stimulating effect on the user is provided. The apparatus comprises a device (10) capable of engaging the patient's skin to provide a rhythmic tactile (10)stimulus to the user that can alter the user's heart rate and an arrangement (12) for securing the device to the user such that the device can apply the stimulus to the user. The apparatus may be part of a system enabling the device (10) to be controlled remotely. The apparatus may also be configured to provide additional tactile stimuli.
Abstract:
Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, breathing rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.
Abstract:
A method for assessing fluid flow in a conduit includes sensing the fluid flow with a sensor and generating data from the sensor that relates to the sensed fluid flow. The data is output from the sensor and filtered so that it may be interpreted to characterize the fluid flow. The conduit may be a prosthesis such as stent, a stent-graft or a prosthetic vascular graft and the flow may be any body fluid such as blood, bile, or cerebrospinal fluid.

Abstract:
Systems and methods for delivering therapy and/or medicament to a subject use one or more sensors to generate signals that represent characteristics of ultrasonic energy emitted during the use of respiratory medicament delivery devices. Parameters based on these signals indicate energy amplitude in one or more frequency ranges. Such parameters can be used to characterize the emitted ultrasonic energy and control and/or monitor device operation and/or patient adherence.
Abstract:
A pen-type drug injection device in which the absolute position of a movable control member (10), such as a dose setting member (32) is determined by at least one transducer responsive to movement of said control member to convert mechanical energy into electrical energy to output an electrical signal, a drive circuit (26) for receiving said electrical signal and for outputting an output drive signal, and a display device (58/62) for receiving said output drive signal and displaying a variable image representing a parameter that varies consequent on said movement. The transducer includes piezoelectric elements (16) which operate switches and the display is a bistable display (14), e.g. an electronic paper display so that the display function is self-powered without a requirement for a battery or the like. The parameter displayed may be for example a dose volume, a count of doses delivered, progress and/or completion of a dose, etc. The drive circuit is an absolute position encoder and detects the actual position of the control member and does not deduce the position by counting pulses.
