The mask body defines an inlet opening and a plurality of leak openings. The blowing assembly is positioned in fluid communication with the inlet opening of the mask body and configured to direct air to the inlet opening of the mask body. The processor is positioned in operative communication with the blowing assembly and the pressure sensor of the mask. The processor is configured to selectively control the blowing assembly based upon at least the measured pressure within the mask.

Disclosed is a manually operable volume-adjustable ventilation device. The device includes a reservoir with an inlet mechanism, an outlet mechanism, and a volume adjuster configured to move a volume adjustment limit of the reservoir and change an expressed maximum volume of the reservoir. The reservoir has a body having a plurality of movable walls defining an enclosed volume. The reservoir has an uncompressed state and a compressed state. The walls of the reservoir are movable with respect to each other, such that moving the walls expresses the volume adjustment limit of the reservoir. The walls can be operably connected by movable structures configured such that two adjacent walls are configured to rotate around substantially orthogonal axes with respect to each other when the reservoir moves from an uncompressed to a compressed state. In some embodiments, the movable structures can be hinges, such as snap-fit assembly hinges. Methods of ventilating a patient that involve the device are also disclosed.

A nasal ventilation mask supplies breathing gas to an airway of a patient. The mask has a housing defining an internal cavity and having a peripheral end defining an end opening. The end opening is in fluid communication with the internal cavity. The end opening is configured to be positioned over an airway on a face of the patient. A sealing member is connected to the housing proximate the end opening. The sealing member extends towards the internal cavity and is configured to abut the face of the patient and deflect towards the internal cavity. The housing further defines a connector assembly having an opening in fluid communication with the internal cavity. The connector assembly is configured to be operably connected to a supply of breathing gas.

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 comprises an insufflated air inlet (2a), an outlet (3a) for said insufflated air provided at the lower end of an air conveying tube (3) designed to penetrate the throat of the victim through the mouth, at least a first one-way valve (4) interposed between said air inlet (2a) and air outlet (3a) to allow the flow of air from said inlet (2a) to said outlet (3a) and prevent the flow of a fluid exhaled by the victim in the opposite direction, the body of said valve (4) including an outlet aperture (4a) for the exit of the fluid exhaled by the victim, and characterized in that the upper end of said insufflated air conveying tube (3) comprises a portion (3b) of tube (3) which is configured for internally receiving the body of said valve (4), the wall of said tube (3) including at least one outer hole (6) communicating with the aperture (4a) of the body of the valve (4) to allow discharging the fluid exhaled by the victim to the outside.

A manual resuscitator regulating system for regulating the rate and volume of ventilation during manual resuscitation. The manual resuscitator regulating system may include an intake assembly configured to permit a selected volume of gas to flow into a chamber over a predetermined amount of time and/or an outtake assembly configured to permit a selected volume of gas flow out of the chamber over a predetermined amount of time. The intake assembly and/or the outtake assembly may include one or more adjustment mechanisms configured to allow a user to selectively adjust volume. The intake assembly and the outtake assembly may be configured to coordinate with one another to deliver a selected tidal volume and/or volume of gas. The manual resuscitator regulating system may include a placement indicator configured to indicate or guide a user where to squeeze or compress the chamber.

A delivery device for use in administering a dry powder to a biological subject's airway is provided. The device comprises (a) a housing having an inlet in fluid communication with an outlet for delivering a flow of gas to the subject's airway; and (b) one or more cantilever structures located within the housing. Vibration of the one or more cantilever structures facilitates entry of the dry powder into the flow of gas, such that the dry powder can be delivered by the flow of gas through the outlet to the subject's airway. Also provided is a container for releasably storing a particulate composition, the container comprising a shell sealed by a seal in which the particulate composition is stored, wherein a puncturing device for rupturing the seal to release the particulate composition is housed within the shell. Further provided are associated methods for administering dry powder using the delivery device and/or container.

The present invention is a mechanical ventilation device which delivers intermittent positive pressure ventilation by compressing AMBU. As the device uses existing AMBU for the ventilation, it is intended to automate the process of hand ventilation and will hence keep the costs and skill requirement low. Due to usage of the AMBU and simple mechanics, it is easy to manufacture and maintain the device.

A feedback device for an acute care provider includes: at least one motion sensor; a haptic output component for providing feedback having a varying haptic pattern to the acute care provider regarding performance of a resuscitation activity; and a controller. The controller can be configured to receive and process a signal representative of performance of the resuscitation activity from the at least one motion sensor, compare the acute care provider's performance of the resuscitation activity to a target performance of the resuscitation activity, and cause the haptic output component to provide haptic feedback to the acute care provider by changing the haptic pattern based, at least in part, on the signal from the at least one motion sensor and the comparison of the acute care provider's performance to the target performance of the resuscitation activity. The device can be adapted to be wrist-worn by the acute care provider.
