  • Patent number: 10758669
    Abstract: An infusion pump includes a housing. The housing includes a tube port adapted to receive an intravenous (“IV”) tube. The tube port includes a tube channel and a rib. The tube channel has an inlet and an outlet end. The rib is positioned along the channel adjacent the outlet end. The rib is formed to extend towards the tube when the tube is passed through the tube port thereby indenting the tube and tending to prevent full occlusion of the tube. The tube port may also include a plurality of ribs positioned around a perimeter of the tube port on the exterior side of the housing. The plurality of ribs are configured to prevent an occlusion in the tube when the tube is bent on the exterior side of the housing.

  • Patent number: 10736523
    Abstract: A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a ‘fiducial’ marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.

  • Patent number: 10729375
    Abstract: The invention provides a sensor for measuring both impedance and ECG waveforms that is configured to be worn around a patient's neck. The sensor features 1) an ECG system that includes an analog ECG circuit, in electrical contact with at least two ECG electrodes, that generates an analog ECG waveform; and 2) an impedance system that includes an analog impedance circuit, in electrical contact with at least two (and typically four) impedance electrodes, that generates an analog impedance waveform. Also included in the neck-worn system are a digital processing system featuring a microprocessor, and an analog-to-digital converter. During a measurement, the digital processing system receives and processes the analog ECG and impedance waveforms to measure physiological information from the patient. Finally, a cable that drapes around the patient's neck connects the ECG system, impedance system, and digital processing system.
