A system for measuring the vital parameters of low care patients is described. The system includes a connecting element for a nasal cannula or breathing mask for providing a fluidic connection with the patient and a flow and/or pressure sensor in fluidic connection with the nasal cannula or breathing mask, for sensing, when the nasal cannula or breathing mask is connected to the system, at least a negative pressure signal. The system also includes a processor configured for deriving, directly based on said at least a negative pressure signal, information related to the breathing cycle, and an output means configured for outputting at least one vital parameter of the patient, the outputting comprising outputting information related to the breathing cycle.

A mechanical ventilation system comprises a mechanical ventilator configured to deliver ventilation to a patient. An electronic controller is programmed to control the mechanical ventilator to perform a mechanical insufflation-exsufflation (MI-E) therapy method including performing a MI-E cycle including: (i) during an insufflation cycle, delivering pressure to the patient at a positive insufflation gauge pressure; (ii) during an exsufflation cycle following step (i), delivering pressure to the patient at a negative exsufflation gauge pressure and detecting whether an upper airway collapse occurs; and (iii) reducing a magnitude of the negative exsufflation gauge pressure if an upper airway collapse is detected in step (ii).

A nasal adaptor includes: an oral expiration guiding portion which has an opposing portion that is to be opposed to the mouth of a living body, and in which a mouth-side guide path that guides expiration that is expired from the mouth to the opposing portion is formed; and an attaching portion which is placed above the oral expiration guiding portion with respect to the living body, and to which a holding member that holds a sensor for measuring the expiration guided by the oral expiration guiding portion is attached. The oral expiration guiding portion is integrally connected to the attaching portion, and has positioning changing portions that change the distances between connecting portions connected to the attaching portion, and the opposing portion, thereby changing the positioning of the opposing portion.

A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly, an exhaled air assembly, and a control system operatively coupled to the inhaled air assembly and the exhaled air assembly. The inhaled air assembly is coupled to a patient respiratory circuit and configured to channel a volume of inhalation air to the patient's lungs to assist in patient inhalation. The exhaled air assembly is coupled to the patient respiratory circuit and configured to remove air from the patent's lungs to assist in a patient exhalation. The control system is configured to operate the respiratory ventilator system in an inhalation mode and an exhalation mode.

An active breathing assistance apparatus is disclosed. A simple apparatus includes first, second and third sets of balloons in a base compartment; a compression component on or over the balloons, configured to expel air from the balloons; a tubing network connected to the balloons; a wearable breathing compartment at an outlet of the tubing network; first and second check valves in the tubing network, between the breathing compartment and (i) the third set of balloons and (ii) the first and/or second balloons, respectively; third and fourth check valves between atmospheric air and the first and second balloons, respectively; a cover securing the compression component to the base compartment; and a motion restricting component controlling movement of the compression component. The first and second sets of balloons are between the compression component and the base compartment, and the third set of balloons is between the compression component and the cover.

The present invention discloses a non-hysteretic oxygen supply respirator system, comprising a respiratory mask, an inhaling pipe, an exhaling pipe, an oxygen supply chamber, an auxiliary oxygen supply pipeline, and a start-stop cylinder for opening and closing the auxiliary oxygen supply pipeline. The non-hysteretic oxygen supply respirator system in the present invention supplies a small amount of oxygen during the second half of exhaling by providing the auxiliary oxygen supply pipeline, so as to compensate for the amount of oxygen required by a user during the hysteretic time after the respirator senses the inhaling airflow, avoid the situation that the user inhales laboriously due to the hysteresis of inhaling oxygen supply, and give the user a better respiratory experience. The start and stop of the auxiliary oxygen supply pipeline are controlled by the airflow of the exhaling pipe, making the control simple and convenient and the exhaling smoother.

The present disclosure pertains to a method and system configured to in-exsufflate a subject by controlling the in-exsufflation pressure waveform. In some embodiments, the system comprises a pressure generator, a subject interface, one or more sensors, one or more processors, electronic storage, a user interface, and/or other components. The system is configured to assist the subject to loosen and/or expel secretions by inducing a percussive pressure waveform delivered to the subject during inhalation and/or exhalation. The system is configured to control the in-exsufflation therapy delivered to the subject without requiring regular manual setting and/or adjustment of pressures, pressure amplitudes, a frequency range, and/or other parameters of the percussive pressure waveform.

A nebulizer assembly for a respiratory device is provided having a housing defining a chamber. The housing also has a nebulizer port configured to receive a nebulizer to discharge atomized medication into the chamber. An outlet of a handle is coupled to the inlet of the housing. A hose is coupled to an inlet of the handle. A patient interface is coupled to the outlet of the housing. Air flows from the hose to the patient interface via the handle and the housing. The air mixes with the atomized medication within the chamber.

A method of providing a breath to a human patient. The patient has a patient connection connected, by a patient circuit, to a ventilator having a first ventilator connection and a different second ventilator connection. Each of the first and second ventilator connections are in fluid communication with the patient circuit. The method includes identifying, with the ventilator, initiation of an inspiratory phase of the breath, delivering a bolus of oxygen to the first ventilator connection before or during the inspiratory phase, and delivering breathing gases comprising air to the second ventilator connection during the inspiratory phase. The ventilator isolates the bolus of oxygen delivered to the first ventilator connection from the breathing gases delivered to the second ventilator connection.

A ventilator apparatus is disclosed that provides various improvements with regard to features and practicality and overall benefits to patients suffering from respiratory and other conditions. The apparatus is constructed in an efficient and reliable way including a single motor and drivetrain assembly that operates a plurality of fluid pumps to achieve the present ventilator functions as described and shown.
