Abstract: Systems and method may be used for interfacing with a patient. Systems may include a plurality of electrodes in electrical communication with a processor. The processor may be configured to receive sense signals from electrodes and to determine the reliability of the received signal. A test tone signal comprising a test tone frequency may be applied, and the magnitude of the test tone frequency may be analyzed in the received signal. If it is determined that the magnitude of the test tone frequency is below a threshold, the system may take action, such as lowering the gain on an amplifier. Stimulation signals may be applied to the patient at a stimulation frequency simultaneously with one or both of receiving sense signals and providing the test tone signal.

Abstract: Bodily fluid indicator devices and methods are provided. Such devices and methods can effectively indicate whether the amount of bodily fluid being produced is within a measurable range. In an exemplary embodiment, a bodily fluid indicator device includes a substrate having a surface. Some portions of the surface are covered with a region of absorbent material and other portions of the surface are devoid of the absorbent material. A graduated scale or a reactive feature is printed on the absorbent material. The device is configured to indicate an amount and/or a composition a bodily fluid present on an area of a patient or subject.

Abstract: An apparatus for determining a respiratory condition, including: a signal acquiring section which is configured to acquire a signal corresponding to a respiratory flow of a subject; a first index producing section which is configured to produce a first index related to the respiratory flow of the subject obtained from the signal; a second index producing section which is configured to produce a second index related to a respiratory demand of the subject predicted from the first index; a third index producing section which is configured to produce a third index related to a respiratory effort of the subject based on the first index and the second index; and an outputting section which is configured to output the third index.

Abstract: A blood pressure measurement cuff wrapped a direction along circumferential direction around a measurement site, the blood pressure measurement cuff containing fluid bladder between belt-shaped body composed of inner cloth to be in contact with the measurement site and outer cloth opposing the inner cloth. Ring attachment member attached to a region on inner circumferential end-side of the outer cloth and hook-and-loop fastener provided in a region on outer circumferential end-side of the inner cloth are included. The ring has a temporary fastening structure that allows a region continuous with outer circumferential end of the belt-shaped body to be pulled through ring with arm strength in a direction away from measurement site during attachment and suppresses a case in which the region continuous with the outer circumferential end of the belt-shaped body pulled by the arm strength is pulled back through the ring by elastic force of the measurement site.

Abstract: Embodiments of the present invention relate to a method for analyzing pulse data. In one embodiment, the method comprises receiving a signal containing data representing a plurality of pulses, the signal generated in response to detecting light scattered from blood perfused tissue. Further, one embodiment includes performing a pulse identification or qualification algorithm on at least a portion of the data, the pulse identification or qualification algorithm comprising at least one constant, and modifying the at least one constant based on results obtained from performing the pulse identification or qualification algorithm, wherein the results indicate that a designated number of rejected pulses has been reached.

Abstract: A blood pressure measurement device includes a cuff and a control unit. The cuff includes a first securing portion, provided on one surface of the cuff, for securing the cuff to the measurement area in a wrapped state, and a second securing portion, provided on another surface of the cuff, for securing the cuff to the measurement area in a wrapped state. At least one of the first securing portion and the second securing portion includes an electromagnet portion. The control unit secures the cuff to the measurement area by controlling a magnetic force emitted from the electromagnet portion and causing the second securing portion to be attracted to the first securing portion.

Abstract: Disclosed herein is a system for monitoring a patient that includes a cuff configured to inflate to at least partially occlude an artery of the patient and a cuff controller configured to inflate the cuff during a dynamic phase and generally maintain inflation of the cuff at about a target pressure during a static phase. The system also includes a sensor configured to receive a signal associated with the at least partially occluded artery and generate an output signal based on the received signal, and a cuff control module configured to determine the target pressure during the dynamic phase and based on the output signal, and control the cuff controller during the dynamic phase and the static phase.

Abstract: In a method for intermittently occluding the coronary sinus, in which the coronary sinus is occluded using an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and stored, the fluid pressure curve is determined as a function of time, and the occlusion of the coronary sinus is triggered and/or released as a function of at least one characteristic value derived from the measured pressure values. The pressure increase and/or pressure decrease per time unit each occurring at a heart beat are used as characteristic values.
