  • Patent number: 11602282
    Abstract: A non-invasive method and system is provided for determining an internal component of respiratory effort of a subject in a respiratory study. Both a thoracic signal (T) and an abdomen signal (A) are obtained, which are indicators of a thoracic component and an abdominal component of the respiratory effort, respectively. A first parameter of a respiratory model is determined from the obtained thoracic signal (T) and the abdomen signal (A). The first parameter is an estimated parameter of the respiratory model that is not directly measured during the study. The internal component of the respiratory effort is determined based at least on the determined first parameter of the respiratory model. The first model parameter is determined based on the thorax signal (T) and the obtained abdomen signal (A) without an invasive measurement.

  • Patent number: 11596318
    Abstract: A method for manufacturing a blood pressure measurement cuff includes preparing an outer cloth, preparing an inner cloth, and forming a bag-shaped portion. The bag-shaped portion has an opening on a peripheral edge of the bag-shaped portion. A curler is inserted into the bag-shaped portion through the opening, the curler being flexible and configured to curve and conform to the measurement site. An air bladder is formed by welding the opening of the bag-shaped portion such that the air bladder surrounds an inner side and an outer side of the curler thereby containing the curler. The outer cloth is attached to an outer surface on a first side of the air bladder configured to be opposite to the measurement site, and the inner cloth is attached to an outer surface on a second side of the air bladder configured to be towards the measurement site.

  • Patent number: 11589814
    Abstract: The disclosure describes a wearable, low-cost and low-power Electrical Impedance Tomography system for gesture recognition. The system measures cross-sectional bio-impedance using electrodes on wearers' skin. Using all-pairs measurements, the interior impedance distribution is recovered, which is then fed to a hand gesture classifier. This system also solves the problem of poor accuracy of gesture recognition often observed with other gesture recognition approaches.

  • Patent number: 11589797
    Abstract: Embodiments of the presently-disclosed subject matter include methods and systems for measuring a level of a neurotransmitter in a subject. Embodiments of the present methods comprise displaying a fixation point, a reward target, and a non-reward target, and measuring one or more saccade movement parameters for reward saccades and non-reward saccades. The saccade movement parameters can include velocity, amplitude, reaction time, or a combination thereof. The present methods can further include determining a reward modulation of the subject, the reward modulation being equal to a difference between the reward and the non-reward values for a respective saccade movement parameter. Some embodiments further include identifying the subject as including a deficiency of the neurotransmitter if there is a statistically measurable difference between the reward modulation of the subject and a reference reward modulation and/or if the non-reward and the reward saccade movement parameters are statistically equivalent.

  • Patent number: 11574741
    Abstract: The systems and methods described herein determine metrics of cardiac or vascular performance, such as cardiac output, and can use the metrics to determine appropriate levels of mechanical circulatory support to be provided to the patient. The systems and methods described determine cardiac performance by determining aortic pressure measurements (or other physiologic measurements) within a single heartbeat or across multiple heartbeats and using such measurements in conjunction with flow estimations or flow measurements made during the single heartbeat or multiple heartbeats to determine the cardiac performance, including determining the cardiac output. By utilizing a mechanical circulatory support system placed within the vasculature, the need to place a separate measurement device within a patient is reduced or eliminated. The system and methods described herein may characterize cardiac performance without altering the operation of the heart pump (e.g., without increasing or decreasing pump speed).

  • Patent number: 11564604
    Abstract: A shieldable needle device including a drive member is disclosed. The drive member is extendable between a biased position and an extended position for moving a tip guard from an first position to a second position in which the tip guard shields a distal end of the needle cannula. The shieldable needle device includes a pair of wings extending laterally from opposing sides of the hub that are movable between a laterally extending position and a dorsal position. With the wings in the dorsal position, the wings retain the drive member in the biased position thereby maintaining the tip guard in the first position. Movement of the wings from the dorsal position to the laterally extending position releases retainment of the drive member. A second drive member may be included.

  • Patent number: 11547316
    Abstract: A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train to the affected tissue. The impedance of the affected tissue is measured, and the measured impedance is correlated to a level of pain in the patient. The pulse train is further applied in response to the measured impedance to reduce the patient's pain. The patient treatment unit includes a probe stimulus generator that outputs the pulse train. The treatment unit also includes a pair of probes for contacting the patient's body and receiving the pulse train. The pulse has improved shaping based on isolation of high voltage from a low voltage control. The unit further includes a body impedance analysis circuit that senses voltage and current via the probes when the probes are contacting the patient and observe the impedance. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain in real-time.

  • Patent number: 11529106
    Abstract: A tool for predicting that a person is likely to be abnormally hydrated over a future time interval, and in some cases to alert the person or a medical professional to intervene. From a series of physiological measurements, a tissue electrical impedance spectrum curve, which comprises a phase spectrum curve in an embodiment, is determined and changes in the shape of the curve are ascertained. The measurements may be received using one or more sensors worn by the person. In some embodiments, current and historic spectrum curvature are applied to an evolutionary algorithm, such as particle-swarm optimization (PSO) or differential evolution (DE), to determine an inference regarding the persons future hydration status. In one embodiment, a statistical forecast for the next epoch immediately beyond the present one, is determined.
