  • Publication number: 20210113800
    Abstract: A patient interface assembly includes a cushion and frame assembly with a cushion portion and a frame portion that together form a breathing chamber. The frame portion includes an anterior aperture configured to receive the flow of breathable gas. Headgear includes a back portion, a pair of upper headgear straps extending from the back portion, and a pair of lower headgear straps. The patient interface assembly also includes a shroud in the form of a contoured plate. The shroud is removably mounted on the frame portion by way of a snap-fit connection and includes a pair of lower headgear connectors. The patient interface assembly also includes a forehead support extending from the shroud and having a free end with an upper headgear connector. The forehead support has a first curvature that curves in a first direction around an axis that is offset from the patient interface assembly and extends along a length of the forehead support.

  • Patent number: 10856802
    Abstract: Methods and apparatus for assessing the condition of and treating patients for heart failure by the delivery of continuous positive airway pressure are disclosed. Treatment of obstruction due to reflex vocal cord closure often experienced by heart failure patients is distinguished from treatment of upper airway obstruction typically associated with Obstructive Sleep Disorder. Treatment may also be implemented by delivering synchronized cardiac pressure oscillations superimposed on a respiratory pressure level to provide assistance for the heart. Heart treatment pressure dose indicator may be calculated for prescribing and monitoring the delivery of treatment. The apparatus may also generate data to track heart failure condition that may be indicative of the degree of severity of heart failure based upon breathing patterns to assist in the diagnosis and management of heart failure patients.

  • Patent number: 10046127
    Abstract: A methodology and apparatus for determining ventilator settings including an end expiratory pressure setting, pressure swing, resistive unloading and target ventilation for delivering ventilatory support based upon generalized patient ventilation characteristics and/or disease classifications. An apparatus may be programmed with the instructions to accomplish the methodology interactively by prompting the user/physician during setup and calculating settings based upon measurements or input responses. Pre-assigned values associated with ventilation characteristics or disease classifications may be combined with a base pressure value or measured values to provide patient customized settings or adjustments to determine pressure levels for the delivery of ventilatory support.

  • Patent number: 9974911
    Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11). The microprocessor (16) controls a servo (19), that in turn controls the fan motor (20) and thus the pressure of air delivered by the blower (10). The blower (10) is coupled to a subject's mask (ii) by a conduit (12). The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

  • Publication number: 20170143928
    Abstract: A headgear for a respiratory mask of a ventilator or CPAP device is provided. The headgear includes a strap portion formed of a substantially inextensible material. The strap portion has formed on one end thereof a connecting structure configured to connect to a mask of the ventilator or CPAP device. One advantage is that the mask will not or at least will be less inclined to lift off the face as mask pressure is increased.

  • Patent number: 9566406
    Abstract: A mask assembly includes a mask with an inflatable bladder. The internal pressure of the inflatable bladder can be set to be higher than the delivered therapeutic pressure. The pressure offset may be constant, or it may vary over the range of therapeutic pressures. Thus, the force necessary to maintain a contact seal between the mask and the patient can be reduced, thereby providing a system that is more comfortable to the patient, which increases patient compliance.

  • Patent number: 9526855
    Abstract: CPAP treatment apparatus is disclosed having a controllable flow generator (34, 38, 40) operable to produce breathable gas at a treatment pressure elevated above atmosphere to a patient by a delivery tube (32) coupled to a mask (30) having connection with a patient's airway. A sensor (44, 50, 56, 58) generates a signal representative of patient respiratory flow, that is provided to a controller (54, 62, 64). The controller (54, 62, 64) is operable to determine the occurrence of an apnea from a reduction in respiratory airflow below a threshold, and if an apnea has occurred, to determine the duration of the apnea and to cause the flow generator (34, 38) to increase the treatment pressure. In one preferred form the increase in pressure is zero if the treatment pressure before the apnea exceeds a pressure threshold.

  • Patent number: 9440038
    Abstract: A method and apparatus for determining suitable settings for a servo-ventilator to be used during a treatment period. Respiratory characteristics of a patient are measured during a learning period preceding the treatment period. With these measured characteristics, a target ventilation setting may be calculated by alternative methods. The calculated setting may then be used for enforcing a minimum ventilation during the treatment period where ventilatory support is provided with a servo-controlled ventilator.

  • Publication number: 20150013679
    Abstract: Method and apparatus for the treatment of cardiac failure, Cheyne Stokes breathing or central sleep apnea are disclosed. A subject is provided with ventilatory support. Respiratory airflow is determined. From the respiratory airflow are derived a measure of instantaneous ventilation (for example half the absolute value of the respiratory airflow) and a measure of longterm average ventilation. A target ventilation is taken as 95% of the longterm average ventilation. The instantaneous ventilation is fed as the input signal to a clipped integral controller, with the target ventilation as the reference signal. The output of the controller determines the degree of ventilatory support. A third measure of ventilation, for example instantaneous ventilation low pass filtered with a time constant of 5 seconds, is calculated. Ventilatory support is in phase with the subject's respiratory airflow to the fuzzy extent that this ventilation is above target, and at a preset rate conversely.
