A ventilator includes a ventilation drive configured to drive ventilation gas from a gas source to a patient and a patient interface section configured to guide inspiratory gas from the ventilation drive to a patient connection, receive expiratory gas from the patient connection, and expel the expiratory gas out of the ventilator. The ventilation drive and patient interface section are configured to removably connect to at least one host comprising a ventilation path portion so as to divert the inspiratory gas through the ventilation path portion of the host when connected thereto.

A CPAP device includes a flow generator, a humidifier, and a connector between the flow generator and the humidifier. The connector includes a connector having an attaching portion and a flexible sealing portion configured to sealingly engage a flat, external surface around a first hole when the humidifier is removably received by a cradle, and the connector forming a passage for pressurized air to flow from the flow generator to the humidifier.

A choking intervention device for clearing a foreign object obstructing a breathing passage of a choking victim includes an assembly of one or more hollow vessels and a facemask configured to enclose a person's mouth and nose. The assembly includes a plurality of vessels configured to create a low-pressure environment within the assembly. The assembly contains a bottom opening which provides access to the low-pressure interior. The facemask is coupled to the bottom of the assembly and is configured to enclose the choking victim's mouth and nose. The body of the assembly is further of proper size and shape to allow an ordinary individual the ability to hold and use the assembly with one hand. Operation of this device has the unique advantage of pressing toward the victim which facilitates the creation of an airtight seal between the facemask and the victim's face.

A patient interface for sealed delivery of a flow of air to ameliorate sleep disordered breathing may include: a seal-forming structure to form a pneumatic seal with the entrance to the patient's airways; a positioning and stabilising structure to maintain the seal-forming structure in sealing contact with an area surrounding the entrance to the patient's airways; a plenum chamber pressurised at a pressure above ambient pressure in use; a connection port for the delivery of the flow of breathable gas into the patient interface; and a device positioned within a breathing chamber defined, at least in part, by the seal-forming structure and the plenum chamber, wherein the device divides the breathing chamber into a posterior chamber and an anterior chamber, and wherein the device comprises a plurality of apertures such that turbulence of the air in the posterior chamber is less than turbulence in the air in the anterior chamber.

A portable digital rectosigmoidoscope single-handed, digital intestinal endoscope, used by suitably trained healthcare workers to digitally view the anus, rectum and distal sigmoid colon in people with anorectal symptoms at point of care.

Methods for using a manually actuated, self-inflating resuscitator device provides users with a positive pressure ventilation device that reliably provides a proper tidal volume to the patient and controls the rate of ventilation of the patient. The resuscitator device is lightweight, compact, durable, and quickly deployable in the field. The resuscitator device is preferably operable with one hand and can be configured for use in low-light environments.

The invention belongs to the field of medical sciences and respiratory masks. It is a cardiopulmonary resuscitation device that delivers assisted ventilation via a foot- or compressor-controlled bellows mechanism. This device frees the use of the hand used to compress the conventional self-inflating Airway Mask Bag Unit (AMBU), so that the free hand can be used to fit the mask over the patient's face and reduce the mechanical fatigue generated by the manual compression of current mechanisms. The unit attaches to ventilation masks, can have a frequency meter and is compatible with accessories comprising conventional cardiopulmonary resuscitation devices; inside it has a valve that controls the filling of the oxygen reservoir and the time at which oxygen is released to be supplied to the patient.

Methods and systems are provided for a ventilation system. In one example, a method includes obtaining one or more patient ventilation parameter images of a patient with the ventilation system while the patient is undergoing mechanical ventilation; obtaining one or more reference ventilation parameter images; processing, with at least one comparison model, each patient ventilation parameter image and each reference ventilation parameter image to characterize at least one feature in each patient ventilation parameter image and each reference ventilation parameter image, including converting each patient ventilation parameter image and each reference ventilation parameter image to a binary mask; identifying, based on of the at least one feature, a deviation between a patient ventilation parameter image and a corresponding reference ventilation parameter image; and in response to the identifying, outputting a notification that indicates the deviation.

A patient interface comprising a cushion having a nasal plenum chamber, an oral plenum chamber, and a passage formed between the nasal and oral plenum chambers. The passage is configured to allow airflow to pass between the nasal and oral plenum chambers. The cushion also includes a valve including valve body and an adjustment structure that is positioned between the nasal chamber and the oral chamber and is movable relative to the valve body. The adjustment structure is movable between an open position that is configured to allow airflow between the nasal plenum chamber and the oral plenum chamber, and a closed position configured to limit airflow between the nasal plenum chamber and the oral plenum chamber. The adjustment structure is configured to allow airflow through a nasal vent in the closed position and is configured to limit airflow through the nasal vent in the open position.

A mechanical ventilator includes an oscillating flow controller, a respiratory interface, and an accumulator having a first variable volume chamber fluidly coupled to a bi-directional fluid port of the flow control valve, a second variable volume chamber fluidly coupled to the respiratory interface, a displaceable diaphragm fluidly separating the first variable volume chamber from the second variable volume chamber, and a biasing element configured to bias the diaphragm in the direction of the first variable volume chamber. In use, the oscillating flow controller provides an oscillating fluid output to the accumulator, thereby causing the accumulator to oscillate between first and second states, wherein the accumulator draws breathing air into the second variable volume chamber when transitioning from the second state to the first state, and wherein the accumulator forces breathing air from the second variable volume chamber to the respiratory interface when transitioning from the first state to the second state.
